本發明係關於一種利 且可調整亮度之LED 明燈之LED照明系統。更詳細而言 用可代替螢光燈使用之LED照明燈 照明系統。 【先前技術】 與白熾燈泡相比，螢光燈之眩光少、發光效率高且壽命 長，因此作為辦公室等之照明燈廣泛使用。螢光燈係由管内 塗佈有螢光物質U空玻璃管及安裝於兩端之電極所構 成’藉由對其兩端之電極施加電壓而產生氣體之放電，從而 發光。於真空玻璃管，封人有少量水銀蒸氣制於容易產生 放電之少量氬氣。 如此構成之螢光燈必須如上述將水銀蒸氣密閉於真空玻 璃管内’而存在有製造困難之問題。又，勞紐之壽命並不 長’當壽命接近結束時亦存在產生嗎之問H肖耗電力 之觀點而言，亦不充分。 101112438 3 201245619 因此，近年來，使用LED作為光源之LED照明燈受到矚 目。就消耗電力及壽命之觀點而言，LED照明燈明顯優於 螢光燈。尤其，只要可將維持螢光燈外觀之LED照明燈代 替螢光燈而安裝於既有之螢光燈照明用器具，則其優點較 大。 然而，既有之螢光燈照明用器具存在有輝光啟動器式、快 速啟動式及反向器式等點燈方式不同者。 輝光啟動器式之螢光燈照明用器具一般由安定器與輝光 啟動器所構成，藉由輝光啟動器之内部所產生之放電而流通 電流，對螢光燈兩端之燈絲進行預熱而點亮螢光燈。快速啟 動式之螢光燈照明用器具具有用於對螢光燈兩端之燈絲進 行預熱之附帶捲線之安定器，藉由對燈絲進行預熱而於燈絲 與啟動輔助導體之間產生微弱之放電，從而點亮螢光燈。反 向器式之螢光燈照明用器具係藉由對商用之交流電源進行 整流及平滑而轉換為20000-100000 Hz之高頻交流，從而點 亮螢光燈。 如此，即便為相同額定電壓之器具，所輸入之電壓、電流、 頻率亦因點燈方式而不同。又，即便為相同之點燈方式，電 壓、電流及頻率之特性亦因製造商而稍微不同。而且，亦存 在如下現狀，即，由位於螢光燈兩端之端子插腳對中哪一個 端子插腳與電源連接係根據螢光燈照明用器具之製造商而 不同。 101112438 4 201245619 於專利文獻1中記載有如下led照明裝置：配置於—端 部之第1及第2電極插腳連接有第1整流電路，配置於另— 端部之第3及笫4電極插腳連接有第2整流電路，且各整淀 電路之直流端子與LED連接。而且，藉由在第1電極插腳 與第2電極插腳之間連接第1電阻電路，在第3電極插腳與 第4電極插腳之間連接第2電阻電路，而可將該lEd照明 裝置安裝於既有之反向器方式之照明用器具中使用。於專利 文獻2中亦§己載有包括特定電阻元件而成之[ED照明燈。 另一方面，多數情況下於辦公室、店鋪、工廠等之天花板 上設置多個可平行絲2個螢紐之倾μ光燈照明用 器具，於其中安裝多個螢光燈而作為整個室内之照明。然 而，由於最近倡導節能，故例如當如白天基本上不太需要照 明之亮度時，大多要求將2個螢光燈中僅拆除其中丨個而進 行點燈。 然而’雙燈用螢光燈照明用器具大多為串聯式，於該情形 時’若關閉2個螢光燈中之！個，則剩餘1個營光燈亦會媳 滅，從而無法實現僅點亮丨個螢光燈之狀態。 於專利文獻3中記載有於位於雙燈用螢光燈照明用器具 中之-插口處安裝包含直流電阻成分較小之通電手段之假 燈管’於另-插π處安通螢光燈，伽亮丨個榮光燈之 螢光燈器具。 [先前技術文獻] 101112438 201245619 [專利文獻] [專利文獻1]日本專利特開2008-277188號公報 [專利文獻2]日本專利特開2〇〇9_272154號公報 [專利文獻3]日本專利特開2〇〇〇_2〇8238號公報 【發明内容】 (發明所欲解決之問題） 與其他兩種方式相比，反向器式螢光燈照明用器具之歷史 尚短，因此普及度較低，且由於反向器電路係由高頻電路所 構成，因此當製造與其相對應之LED照明燈時，需要較多 之零件而使成本提南之可能性較高。 另-方面，輝光啟動器式及快速啟動式勞光燈照明用器具 歷史悠久而以壓倒性數量大量出現於市場上，其巾快迷啟動 式之營光燈照明用H具之普及率較高i此，若能夠實現可 尤其安裝於快速啟動式之螢光燈照明用器具中之LED照明 燈，則於普及面及成本方面均為有利。 然而，由於對應於快速啟動式之螢光燈照明用器具之[ED 照明燈-般具有關控制方式之整流電路，因此存在產生導 致PSI電波干擾之高頻雜訊之問題。又，於快速啟動式之榮 光燈照明用器具之情形時，由於施加至螢光燈所包含之4 個ACXAlternating CUrrent，交流）輸入插腳之電壓稍微不 同’因此迄今為止之LED，腿減生衫穩定性缺之、 閃爍等問題。 101112438 6 201245619 又’藉由假燈管而僅點亮i個營光燈之螢光燈器具不僅外 觀不美，有時亦產生突_為—半亮度而過暗之問題。進 而’於快速啟動式之#光燈照明用器具巾安裝有假燈管之情 形時，由於假燈管亦消耗與普通螢光燈相同之電力，因此實 際上並不節能。 因此’本發明之目的在於提供一種即便不使用開關控制方 式之整流電路，尤其可衫於快速啟動式之朗用器具之 LED照明燈及具有該LED照明燈之led照明裝置。又，本 發明之目的在於提供一種使用該LED照明燈，可調整亮度 之LED照明系統。 (解決問題之手段） 本叙明之LED照明燈係可裝卸於螢光燈照明用器具之 LED照明燈，其具有： 第1及第2AC輸入插腳，其設置於一端部； 第3及弟4AC輸入插腳’其設置於另一端部； 第1〜第4橋式整流電路，其於上述第1〜第4AC輸入插 腳分別連接有一 AC端子，並使另一 AC端子分別共用共通 端子而相互連接； 第1

本發明之LED照明系統具有上述LED照明燈、點亮上述 LED照明燈之照明用器具及調整上述LED照明燈之亮度之 調光器。 (發明效果） 根據本發明’可提供一種即便不使用開關控制方式之整流 電路，尤其可安裝於快速啟動式之照明用器具之LED照明 燈及具有該LED照明燈夂LED照明裝置。又，根據本發明， 可提供一種使用該LED照明燈，並可調整亮度之lED照明 系統1 【實施方式】 < LED照明燈> 將本發明之LED照明燈之一實施形態中之電路構成示於 圖1。於該LED照明燈之一端部設置有第丨Ac輸入插腳U 及第2AC輸入插腳12,於另—端部設置有第3aC輸入插腳 13及第4AC輸入插腳14。若將LED照明燈設置於照明用 器具，則自該等AC輸入插腳輸入AC電壓。 於第1AC輸入插腳11連接有第1橋式整流電路21中之 一 AC端子。於第2AC輸入插腳12連接有第2橋式整流電 路22中之一 AC端子。於第3 AC輸入插腳13連接有第3 101112438 8 201245619 橋式整流電路23中之一 AC端子。於第4AC輸入插腳14 連接有第4橋式整流電路24中之一 AC端子。而且，第1 〜第4橋式整流電路21〜24中之另一 AC端子均共用共通 端子CO.M而相互連接。 藉由形成此種電路，於第1AC輸入插腳11與第3AC輸 入插腳13之間、第2AC輸入插腳12與第3AC輸入插腳13 之間、第1AC輸入插腳11與第4AC輸入插腳14之間、第 2AC輸入插腳π與第4AC輸入插腳14之間的任一者均並 列連接有2個橋式整流電路。即，由於輸入至LED照明燈 之AC電壓被分壓而均等施加於並列連接之橋式整流電 路’因此於各橋式整流電路中可獲得特定DC電壓。再者， 本案申請人將該電路命名為超矩陣(super matrix)電路。 於第1橋式整流電路21及第2橋式整流電路22之DC端 子側連接有包含LED發光元件30之第1LED發光電路31。 又’於第3橋式整流電路23及第4橋式整流電路24之DC 端子側連接有包含LED發光元件30之第2LED發光電路 32。藉此，第1LED發光電路31所具有之LED發光元件30 可藉由自第1橋式整流電路21或第2橋式整流電路22之 DC端子所輸出之DC電流而發光，第2LED發光電路32所 具有之LED發光元件30可藉由自第3橋式整流電路23或 第4橋式整流電路24之DC端子所輸出之DC電流而發光。 即，由於如上述般採用超矩陣電路，故第1LED發光電路 101112438 9 201245619 31所具有之LED發光元件3〇與第2LED發光電路以所具 有之LED發光元件30可分別獨立地發光。 第1LED發光電路31及第2LED發光電路32雖可分別由 1個LED發光元件3G所構成’但通f具有串列及/或並列連 接之複數個LED發光元件3〇<5丨個LED發光電路所包含之 LED發光元件30之個數只要根據所需之亮度、電壓、瓦特 數等適當設定即可，但較佳為2G〜·個，更佳為4〇〜2〇() 個，進而較佳為60〜150個。 第1LED發光電路31及第2LED發光電路32所具有之 LED發光元件30可為紅色LED發光元件、橙色LED發光 元件、黃色LED發光元件、綠色LED發光元件、藍色led 發光元件及白色LED發光元件中之任一者，但若考慮安裝 使用於照明用器具’則較佳為白色LED發光元件。 於如上述之電路構成中，於在第1AC輸入插腳u與第 3AC輸入插腳13之間施加有AC電壓之情形時，第丨橋式 整流電路21與第3橋式整流電路23發揮功能，第1LED# 光電路31及第2LED發光電路32所具有之LEd發光元件 30發光。於在第1AC輸入插腳11與第4AC輪入插腳14之 間施加有AC電壓之情形時’第1橋式整流電路21與第4 橋式整流電路24發揮功能，第1LED發光電路31及第2LED 發光電路32所具有之LED發光元件30發光。於在第2AC 輸入插腳12與第3 AC輸入插腳13之間施加有ac電壓之 101112438 10 201245619 情形時，第2橋式整流電路22與第3橋式整流電路23發揮 功能’第1LED發光電路31及第2LED發光電路32所具有 之LED發光元件30發光。於在第2AC輸入插腳12與第4AC 輸入插腳14之間施加有AC電麈之情形時，第2橋式整流 電路22與第4橋式整流電路24發揮功能，第ilED發光電 路31及第2LED發光電路32所具有之LED發光元件30發 光。 即，藉由利用如上述之超矩陣電路構成LED照明燈，於 第1AC輸入插腳11與第3AC輸入插腳13之間、第2AC 輸入插腳12與第3AC輸入插腳13之間、第1AC輸入插腳 11與第4AC輸入插腳14之間、第2AC輸入插腳12與第 4AC輸入插腳14之間的任一者施加AC電壓，最終第1LED 發光電路31及第2LED發光電路32所具有之LED發光元 件30均可發光。 但是，由於自橋式整流電路之DC端子輸出之DC電流成 為具有週期性之波形之脈動流，因此若僅藉由上述構成而直 接輸入至LED發光電路，則LED發光元件30發出之光之 強度產生波動，而導致閃爍。 因此，本發明之LED照明燈較佳為包括：第1平滑電路 41，其使自第1橋式整流電路21及第2橋式整流電路22 之DC端子輸出之DC電流平滑化；及第2平滑電路42 ’其 使自第3橋式整流電路23及第4橋式整流電路24之DC端 101112438 11 201245619 子輸出之DC電流平滑化。藉由導入該等平滑電路而可防止 閃爍。平滑電路係具有利用電容器或抗流圈等之特性而使脈 動流之波形更接近平坦之功能之電路。 進而，本發明之LED照明燈較佳為包含：第i定電流電 路51，其使流通於第1LED發光電路31中之DC電流固定； 及第2定電流電路52，其使流通於第2LED發光電路32中 之DC電流固定。作為用於構成定電流電路之元件，可列舉 定電流二極體、三端調壓器、電晶體等，但較佳為使用三端 調壓器。圖2中表示有形成三端調壓器55中連接有電阻Rd 之電路作為第1定電流電路51之例。於該定電流電路中， 藉由適當調整電阻Rd之電阻偉，而可獲得大致固定之電流。 另一方面’即便關閉開關而停止施加電壓，LEd發光元 件30亦因殘留於第ilED發光電路31及第2LED發光電路 32中之電壓而不會熄滅’暫時保持發光之狀態。 因此，本發明之LED照明燈較佳為包含：第1殘餘電壓 消除電路61，其於關閉開關時去除殘留於第1LED發光電 路31中之電壓；及第2殘餘電壓消除電路62，其去除殘留 於第2LED發光電路32中之電壓。作為殘餘電壓消除電路， 例如可形成LED發光電路中並列連接有電阻之電路。圖2 中表示有形成連接有電阻RC之電路作為第1殘餘電壓消除 電路61之例。此時’於將電阻Rc之電阻值設為心，將與 該電阻並列連接之第1LED發光電路31之電阻值設為R〇 101112438 12 201245619 時，只要滿足下式（1): R〇xRi/(R〇 + Ri)> R〇 ⑴ 則可於0· 1 sec以内去除殘餘電壓。 本發明之LED照明燈形成可裝卸於螢光燈照明用器具等 照明用器具中之形狀。即，LED照明燈具有與迄今為止所 使用之螢光燈相同或實質上相同之外觀形狀，從而可代替迄 今為止所使用之螢光燈而安裝於螢光燈照明用器具中。作為 螢光燈之形狀，一般而言，已知有直管形、環形、緊湊型、 燈泡形等，LED照明燈亦可為該等形狀。但是，如上所述， 由於LED照明燈具有4個AC輸入插腳，因此通常具有與 直管形螢光燈相同或實質上相同之外觀形狀。再者，於具有 可裝卸於水銀燈等燈泡形照明用器具中之形狀之LED照明 燈之情形時，藉由2個AC輸入插腳而並非4個AC輸入插 腳來點亮LED照明燈。於該情形時，成為組合使用第1或 第2AC輸入插腳之1者與第3或第4AC輸入插腳之1者， 另一 AC輸入插腳未連接之狀態。 將本發明之直管形LED照明燈之一實施形態中之構成構 件示於圖4及圖5。該直管形LED照明燈係形成為半圓筒 狀之基座1與形成為半圓筒狀之遮罩3以彼此之開口部相對 之方式結合’其兩端部由設置有2個AC輸入插腳之封蓋4 及5所覆蓋，由此形成與直管形螢光燈相同或實質上相同之 外觀形狀。 101112438 13 201245619 於基座1上以覆蓋其開口部之方式設置平板，且於該平板 之遮罩3侧配置LED發光元件。基座1與平板可裝卸，亦 可黏著。例如，於圖4所示之直管形LED照明燈中，於基 座1上以覆蓋其開口部之方式設置附帶LED發光元件之平 板2 ’ LED發光元件30配置於附帶LED發光元件之平板2 之遮罩3側之表面。另一方面’於圖5所示之直管形led 照明燈中’基座1與覆蓋其開口部之平板2a為一體，包含 LED發光元件3〇之LED發光元件基板2b設置於平板2a 之遮罩3側之表面。 為提高散熱性，基座1通常由鋁等所形成。進而，較佳為 於基座1之内部表面設置有用於散發自LED發光元件30產 生之熱之散熱片（未圖示）。藉由散熱片，可有效散發自led 發光兀件30產生之熱，從而防止因過熱而導致之led照明 燈之損傷°為提高散熱性，附帶LEd發光元件之平板2及 平板2a通常亦由鋁等所形成。 遮罩3只要具有使來自LED發光元件30之光透過之性質 即可’可為玻璃’但通常由矽樹脂、丙烯酸樹脂、聚碳酸酯 樹脂等具有透光性之樹脂所形成。而且，較佳為對遮罩3 之内部表面進行磨砂加工（加工為磨砂玻璃狀）。來自LED 發光元件30之光之指向性雖強，但藉由對遮罩3之内部表 面進行磨砂加工，來自LED發光元件30之光產生漫反射， 整體發出類似螢光燈之光。 101112438 14 201245619 於此種構成之直官形LED照明燈中，以設置於—封蓋之 2個AC輸人插腳成為第丨及第輸人插腳，m於另一 封蓋之2個AC輪人插腳成為第3及第4AC輸人插腳之方 式形成上述電路。而且，藉由將第2及第几印發光電路<未

本發明之LED照明系統包括上述照明 及、上述照明用器 101112438 15 201245619 具及調整亮度之調光器。若為此一構成，則即便LED照明 燈未使用開關控制方式之整流電路，不僅可特別安裝於快速 啟動式之螢光燈照明用器具，亦可藉由調光器調整LED照 明燈之亮度。例如當如白天般基本不需要照明之亮度時’可 藉由調光器簡便地控制LED照明燈之亮度，使電力消耗量 相應減少，故而節能。 於本發明之LED照明系統中，使用調整上述LED照明燈 之亮度之調光器。由於上述LED照明燈採用超級矩陣電 路，因此其亮度相對於輸入電壓之變化而連續變化。即，本 發明之LED照明系統例如可藉由使用由可調變壓器調整電 壓之輸入自由導通（input free 〇N)方式之調光器而簡便地進 行調光。 此處，一般而言’廣泛採用使用稱為三端雙向可控矽開關 之電子元件之相位控制方式之調光器，而非輸入自由導通方 式之調光器。因此’只要可使用相位控制方式之調光器，則 於有效利用已有設備方面優點較大。然而，若直接使用相位 控制方式之調光器’則LED照明燈中可觀察到斷續之閃爍。 使用圖6對其不同點進行說明。由輸入自由導通方式之調 光器控制之電壓波形1〇1成為AC電壓波形100維持著正弦 波形狀而振幅較小之波形（圖6(a))。與此相對，由相位控制 方式之調光器控制之電壓波形1〇2成為AC電壓波形100之

brightness. More specifically, an LED lighting system that can be used in place of a fluorescent lamp. [Prior Art] Fluorescent lamps are widely used as illumination lamps for offices, etc., because they have less glare, higher luminous efficiency, and longer life than incandescent bulbs. The fluorescent lamp is formed by a fluorescent material U-coated glass tube and electrodes attached to both ends of the tube, and a gas is generated by applying a voltage to electrodes on both ends thereof to emit light. In the vacuum glass tube, a small amount of mercury vapor is sealed to make a small amount of argon which is easy to generate discharge. The fluorescent lamp thus constructed must have a problem in that it is difficult to manufacture by sealing the mercury vapor in the vacuum glass tube as described above. Moreover, the life of the labor is not long. 'When the life expectancy is nearing the end, there is also a problem that the power consumption is not sufficient. 101112438 3 201245619 Therefore, in recent years, LED illumination lamps using LEDs as light sources have been attracting attention. In terms of power consumption and longevity, LED lighting is clearly superior to fluorescent lamps. In particular, as long as the LED lighting lamp that maintains the appearance of the fluorescent lamp can be installed in an existing fluorescent lamp lighting device instead of the fluorescent lamp, the advantage is large. However, there are different types of lighting devices such as a glow starter type, a quick start type, and an inverter type. A glow starter type fluorescent lamp illumination device generally consists of a ballast and a glow starter, and a current is passed through a discharge generated inside the glow starter to preheat the filaments at both ends of the fluorescent lamp. Bright fluorescent light. The quick-start fluorescent lamp illumination device has a ballast with an auxiliary winding for preheating the filaments at both ends of the fluorescent lamp, and the filament is preheated to create a weak relationship between the filament and the auxiliary auxiliary conductor. Discharge, thus lighting the fluorescent lamp. The reflector type fluorescent lamp illumination device converts the high frequency AC of 20000-100000 Hz by rectifying and smoothing the commercial AC power source, thereby illuminating the fluorescent lamp. Thus, even for appliances of the same rated voltage, the input voltage, current, and frequency are different depending on the lighting method. Moreover, even with the same lighting method, the characteristics of voltage, current and frequency are slightly different depending on the manufacturer. Further, there is also a situation in which which of the terminal pin pairs located at both ends of the fluorescent lamp is connected to the power source differs depending on the manufacturer of the fluorescent lamp lighting device. Patent Document 1 discloses a LED illumination device in which a first rectifier circuit is connected to first and second electrode pins disposed at an end portion, and third and fourth electrode pins are disposed at another end portion. There is a second rectifier circuit, and the DC terminals of the respective precipitation circuits are connected to the LEDs. Further, by connecting the first resistance circuit between the first electrode pin and the second electrode pin, the second resistance circuit is connected between the third electrode pin and the fourth electrode pin, and the lEd illumination device can be attached to both It is used in lighting appliances with reverser type. Also in Patent Document 2, there is a [ED illumination lamp including a specific resistance element. On the other hand, in many cases, a plurality of tilting-light lamps for two parallel-connected filaments are installed on the ceiling of an office, a shop, a factory, etc., and a plurality of fluorescent lamps are installed therein as illumination for the entire room. . However, since energy conservation has recently been advocated, for example, when there is substantially no need for illumination in the daytime, it is often required to remove only one of the two fluorescent lamps and turn on the light. However, most of the lamps for dual-lamp fluorescent lighting are in series. In this case, turn off the two fluorescent lamps! The remaining one of the camplights will also be extinguished, making it impossible to illuminate only one fluorescent light. Patent Document 3 discloses that a fluorescent tube that includes an energizing means having a small DC resistance component is attached to a socket for a dual-lamp fluorescent lamp illumination device, and a fluorescent lamp is installed in another π-intersection. Glittering a fluorescent lamp with a glory lamp. [Prior Art Document] 101112438 201245619 [Patent Document 1] Japanese Patent Laid-Open Publication No. 2008-277188 (Patent Document 2) Japanese Patent Laid-Open Publication No. Hei No. Hei. 〇〇〇_2〇8238(Summary of the Invention) (Problems to be Solved by the Invention) Compared with the other two methods, the history of instruments for inverter-type fluorescent lamps is short, and thus the popularity is low. Moreover, since the inverter circuit is composed of a high-frequency circuit, when the LED lighting lamp corresponding thereto is manufactured, more parts are required, and the possibility of raising the cost is high. On the other hand, the glow starter and quick-start type of worklights have a long history and are widely available in the market in an overwhelming number. In this case, it is advantageous in terms of both the popularization surface and the cost, if an LED illumination lamp that can be particularly mounted in a quick-start type fluorescent lamp illumination device can be realized. However, since the [ED illumination lamp of the quick-start type fluorescent lamp illumination device has a rectification circuit having a control mode, there is a problem that high frequency noise is generated which causes PSI radio wave interference. Moreover, in the case of the fast-starting glory lighting device, the voltage of the AC input pin is slightly different due to the application of the four ACX Alternating CUrrents included in the fluorescent lamp. Sexual deficiency, flickering and other issues. 101112438 6 201245619 In addition, the fluorescent lamp device that illuminates only i camplights with a false lamp is not only unsightly, but sometimes has a problem of half brightness and too dark. Further, when the flashlight tube is mounted on the quick-start type of light-emitting instrument wiper, since the dummy tube consumes the same electric power as the ordinary fluorescent lamp, it is practically not energy-saving. Accordingly, it is an object of the present invention to provide an LED illumination lamp and a LED illumination device having the LED illumination lamp, even if the rectifier control circuit is not used. Further, it is an object of the present invention to provide an LED illumination system which can adjust brightness using the LED illumination lamp.

The LED lighting device of the present invention includes the above-described LED lighting lamp and an illumination device capable of attaching and detaching the LED lighting lamp. The LED lighting system of the present invention includes the above-described LED illumination lamp, an illumination device for lighting the LED illumination lamp, and a dimmer for adjusting the brightness of the LED illumination lamp. (Effect of the Invention) According to the present invention, it is possible to provide an LED illumination lamp which can be attached to a quick-start type lighting fixture and a LED illumination device having the same, even if the rectifier control circuit is not used. Moreover, according to the present invention, it is possible to provide a lED illumination system 1 that uses the LED illumination lamp and can adjust the brightness. [Embodiment] <LED illumination lamp> The circuit configuration of one embodiment of the LED illumination lamp of the present invention Shown in Figure 1. The second input pin U and the second AC input pin 12 are provided at one end of the LED illumination lamp, and the third aC input pin 13 and the fourth AC input pin 14 are provided at the other end. When the LED illumination lamp is installed in the illumination device, the AC voltage is input from the AC input pins. One of the first bridge rectifier circuits 21 is connected to the first AC input pin 11. An AC terminal of the second bridge rectifier circuit 22 is connected to the second AC input pin 12. One of the AC terminals of the third 101112438 8 201245619 bridge rectifier circuit 23 is connected to the third AC input pin 13. One of the AC terminals of the fourth bridge rectifier circuit 24 is connected to the fourth AC input pin 14. Further, the other AC terminals of the first to fourth bridge rectifier circuits 21 to 24 share the common terminal CO.M and are connected to each other. By forming such a circuit, between the first AC input pin 11 and the third AC input pin 13, between the second AC input pin 12 and the third AC input pin 13, between the first AC input pin 11 and the fourth AC input pin 14, Two bridge rectifier circuits are connected in parallel to any of the second AC input pin π and the fourth AC input pin 14. That is, since the AC voltage input to the LED illumination lamp is divided and equally applied to the bridge rectifier circuit which is connected in parallel, a specific DC voltage can be obtained in each bridge rectifier circuit. Furthermore, the applicant of the case named the circuit a super matrix circuit. A first LED light-emitting circuit 31 including an LED light-emitting element 30 is connected to the DC terminal side of the first bridge rectifier circuit 21 and the second bridge rectifier circuit 22. Further, a second LED light-emitting circuit 32 including the LED light-emitting element 30 is connected to the DC terminal side of the third bridge rectifier circuit 23 and the fourth bridge rectifier circuit 24. Thereby, the LED light-emitting element 30 included in the first LED light-emitting circuit 31 can emit light by the DC current output from the DC terminal of the first bridge rectifier circuit 21 or the second bridge rectifier circuit 22, and the second LED light-emitting circuit 32 can emit light. The LED light-emitting element 30 can emit light by a DC current output from the DC terminal of the third bridge rectifier circuit 23 or the fourth bridge rectifier circuit 24. That is, since the super-matrix circuit is used as described above, the LED light-emitting elements 3A and the second LED light-emitting circuits of the first LED light-emitting circuit 101112438 9 201245619 31 can independently emit light independently of the LED light-emitting elements 30. The first LED light-emitting circuit 31 and the second LED light-emitting circuit 32 may each be composed of one LED light-emitting element 3G. However, the plurality of LED light-emitting elements are connected in series and/or in parallel. 3 〇 LED illumination The number of the LED light-emitting elements 30 included in the circuit may be appropriately set according to the required brightness, voltage, wattage, etc., but is preferably 2 G to ·, more preferably 4 to 2 (), and further It is preferably 60 to 150. The LED light-emitting elements 30 included in the first LED light-emitting circuit 31 and the second LED light-emitting circuit 32 may be red LED light-emitting elements, orange LED light-emitting elements, yellow LED light-emitting elements, green LED light-emitting elements, blue led light-emitting elements, and white LED light-emitting elements. Any of them is preferably a white LED light-emitting element if it is considered to be mounted for use in a lighting fixture. In the above-described circuit configuration, when the AC voltage is applied between the first AC input pin u and the third AC input pin 13, the second bridge rectifier circuit 21 and the third bridge rectifier circuit 23 function. The LEd light-emitting elements 30 included in the 1 LED# optical circuit 31 and the second LED light-emitting circuit 32 emit light. When the AC voltage is applied between the first AC input pin 11 and the fourth AC wheel pin 14, the first bridge rectifier circuit 21 and the fourth bridge rectifier circuit 24 function, and the first LED light-emitting circuit 31 and the second LED are provided. The LED light-emitting element 30 included in the light-emitting circuit 32 emits light. When the ac voltage is applied between the second AC input pin 12 and the third AC input pin 13, 101112438 10 201245619, the second bridge rectifier circuit 22 and the third bridge rectifier circuit 23 function as the first LED light-emitting circuit 31. The LED light-emitting element 30 included in the second LED light-emitting circuit 32 emits light. When the AC power is applied between the second AC input pin 12 and the fourth AC input pin 14, the second bridge rectifier circuit 22 and the fourth bridge rectifier circuit 24 function, and the il ED circuit 31 and the second LED are provided. The LED light-emitting element 30 included in the light-emitting circuit 32 emits light. That is, the LED illumination lamp is configured by the above-described super-matrix circuit between the first AC input pin 11 and the third AC input pin 13, between the second AC input pin 12 and the third AC input pin 13, and the first AC input pin 11 An AC voltage is applied between the fourth AC input pin 14 and the second AC input pin 12 and the fourth AC input pin 14, and finally the LED light-emitting elements 30 included in the first LED light-emitting circuit 31 and the second LED light-emitting circuit 32 are both Can be illuminated. However, since the DC current outputted from the DC terminal of the self-bridge rectifier circuit becomes a pulsating flow having a periodic waveform, if the LED light-emitting circuit is directly input only by the above configuration, the intensity of the light emitted from the LED light-emitting element 30 is obtained. Fluctuations occur, causing flicker. Therefore, the LED illumination lamp of the present invention preferably includes a first smoothing circuit 41 that smoothes the DC current output from the DC terminals of the first bridge rectifier circuit 21 and the second bridge rectifier circuit 22; The smoothing circuit 42' smoothes the DC current output from the DC terminals 101112438 11 201245619 of the third bridge rectifier circuit 23 and the fourth bridge rectifier circuit 24. Flicker can be prevented by introducing these smoothing circuits. The smoothing circuit has a function of making the waveform of the pulsating flow closer to flat by utilizing characteristics such as a capacitor or a choke coil. Further, the LED illumination lamp of the present invention preferably includes an i-th constant current circuit 51 that fixes a DC current flowing through the first LED light-emitting circuit 31, and a second constant current circuit 52 that emits light through the second LED. The DC current in circuit 32 is fixed. Examples of the element for constituting the constant current circuit include a constant current diode, a three-terminal voltage regulator, a transistor, and the like, but a three-terminal voltage regulator is preferably used. Fig. 2 shows an example in which a circuit in which a resistor Rd is connected to the three-terminal regulator 55 is formed as the first constant current circuit 51. In the constant current circuit, a substantially constant current can be obtained by appropriately adjusting the resistance of the resistor Rd. On the other hand, even if the voltage is stopped and the voltage is stopped, the LEd light-emitting element 30 does not extinguish due to the voltage remaining in the il ED light-emitting circuit 31 and the second LED light-emitting circuit 32. Therefore, the LED illumination lamp of the present invention preferably includes a first residual voltage eliminating circuit 61 that removes a voltage remaining in the first LED lighting circuit 31 when the switch is turned off, and a second residual voltage eliminating circuit 62 that removes the residual The voltage in the second LED lighting circuit 32. As the residual voltage eliminating circuit, for example, a circuit in which a resistor is connected in parallel in the LED lighting circuit can be formed. Fig. 2 shows an example in which a circuit in which a resistor RC is connected is formed as the first residual voltage canceling circuit 61. In this case, when the resistance value of the resistor Rc is set to the center and the resistance value of the first LED lighting circuit 31 connected in parallel with the resistor is R〇101112438 12 201245619, the following formula (1) is satisfied: R〇xRi/ (R〇+ Ri)> R〇(1) removes the residual voltage within 0·1 sec. The LED illuminating lamp of the present invention has a shape that can be detachably attached to an illuminating device such as a fluorescent lamp lighting device. In other words, the LED illuminating lamp has the same or substantially the same external shape as the fluorescent lamp used so far, and can be attached to the fluorescent lamp illuminating device instead of the fluorescent lamp used so far. As the shape of the fluorescent lamp, generally, a straight tube shape, a ring shape, a compact shape, a bulb shape, and the like are known, and the LED illumination lamp may have such a shape. However, as described above, since the LED illumination lamp has four AC input pins, it generally has the same or substantially the same appearance shape as the straight tubular fluorescent lamp. Further, in the case of an LED illumination lamp having a shape that can be attached to a light bulb-shaped illumination device such as a mercury lamp, the LED illumination lamp is illuminated by two AC input pins instead of four AC input pins. In this case, one of the first or second AC input pins is used in combination with one of the third or fourth AC input pins, and the other AC input pin is not connected. The constituent members of one embodiment of the straight tubular LED illumination lamp of the present invention are shown in Figs. 4 and 5. The straight tubular LED lighting lamp is formed in a semi-cylindrical base 1 and the semi-cylindrical mask 3 is coupled to each other in an opening portion. The two end portions are provided with two AC input pins. The covers 4 and 5 are covered, thereby forming the same or substantially the same appearance shape as the straight tubular fluorescent lamp. 101112438 13 201245619 A flat plate is provided on the susceptor 1 so as to cover the opening thereof, and an LED light-emitting element is disposed on the side of the mask 3 of the flat plate. The base 1 and the flat plate are detachable and can be attached. For example, in the straight tube type LED illumination lamp shown in FIG. 4, the flat plate 2 with the LED light emitting element is disposed on the susceptor 1 so as to cover the opening portion thereof. The LED light emitting element 30 is disposed on the flat plate 2 with the LED light emitting element. The surface of the mask 3 side. On the other hand, in the straight tubular LED illumination lamp shown in FIG. 5, the susceptor 1 is integrated with the flat plate 2a covering the opening portion thereof, and the LED light-emitting element substrate 2b including the LED light-emitting element 3 is disposed on the flat plate 2a. The surface on the side of the cover 3. In order to improve heat dissipation, the susceptor 1 is usually formed of aluminum or the like. Further, it is preferable that a heat sink (not shown) for dissipating heat generated from the LED light-emitting element 30 is provided on the inner surface of the susceptor 1. The heat generated by the LED light-emitting element 30 can be effectively dissipated by the heat sink, thereby preventing damage of the led light caused by overheating. To improve heat dissipation, the flat plate 2 and the flat plate 2a with LEd light-emitting elements are usually also made of aluminum. Waiting for it to form. The mask 3 may be made of a resin that transmits light from the LED light-emitting element 30, but may be glass, but is usually made of a light-transmitting resin such as a enamel resin, an acrylic resin, or a polycarbonate resin. Further, it is preferable that the inner surface of the mask 3 is subjected to a sanding process (processed into a frosted glass shape). Although the directivity of the light from the LED light-emitting element 30 is strong, by performing the sanding process on the inner surface of the mask 3, the light from the LED light-emitting element 30 is diffusely reflected, and a light similar to a fluorescent lamp is emitted as a whole. 101112438 14 201245619 In the direct-shaped LED lighting lamp of this type, the two AC input pins disposed on the cover are the first and the second input pins, and the two AC wheels on the other cover. The above-mentioned circuit is formed in such a manner that the pins become the third and fourth AC input pins. Further, the second and the plurality of printed light-emitting circuits <not shown are formed on the side of the mask 3 of the flat plate, and the coffee-emitting element % is disposed so as to face the mask 3 side of the flat plate. The bridge circuit, the smoothing circuit, the constant current circuit, and the residual f (four) dividing circuit may be formed on the base i side of the flat plate, or may be formed on the wire plate in a space formed by the self-sewing and the flat plate. <LED Illumination Device> An LED illumination device is formed by attaching the LED illumination lamp of the present invention to a lighting fixture that can be attached and detached. Furthermore, it is assumed that the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ , Tian as a lighting method for lighting fixtures, ... know that there are glow starter type, quick connect start type, reverse type, etc., the hair 仏 red ^ LED lighting can be installed in any One type of device for fluorescent lighting. A led illuminator is mounted on a quick-start fluorescent lamp. As a general rule, it will be operated. However, the LED illuminator of the present invention must be installed in the fast-starting fluorescent lamp up to now. In any operation, the side lighting system can be used. The LED lighting system of the present invention includes the above illumination and the above-mentioned illumination device 101112438 15 201245619 and a dimmer for adjusting brightness. According to this configuration, even if the LED lighting lamp does not use the switching control type rectifier circuit, it can be specially installed not only in the quick-start type fluorescent lamp lighting device but also in adjusting the brightness of the LED lighting lamp by the dimmer. For example, when the brightness of the illumination is substantially unnecessary as in the daytime, the brightness of the LED illumination lamp can be easily controlled by the dimmer, so that the power consumption is reduced correspondingly, thereby saving energy. In the LED lighting system of the present invention, a dimmer for adjusting the brightness of the above LED lighting lamp is used. Since the above LED lighting lamp uses a super-matrix circuit, its brightness continuously changes with respect to changes in the input voltage. That is, the LED illumination system of the present invention can be easily dimmed, for example, by using a dimmer of an input free 〇N type that is adjustable by a variable transformer. Here, in general, a dimmer using a phase control method of an electronic component called a three-terminal bidirectional controllable switch is widely used instead of a dimmer that inputs a free conduction mode. Therefore, as long as a phase control type dimmer can be used, there is a great advantage in effectively utilizing existing equipment. However, if the phase control mode dimmer is used directly, intermittent flashing can be observed in the LED illumination. The differences will be described using FIG. 6. The voltage waveform 1〇1 controlled by the dimmer input to the free conduction mode becomes a waveform in which the AC voltage waveform 100 maintains a sine wave shape and has a small amplitude (Fig. 6(a)). On the other hand, the voltage waveform 1〇2 controlled by the phase control type dimmer becomes a waveform in which a part of the AC voltage waveform 100 is OFF (open) and is deformed (Fig. 6(b)). The above flash 101112438 16 201245619 is caused by the voltage waveform of the deformation of the self-phased red material. Therefore, in the case of using a phase control type dimmer, it is preferable to arrange a control transformer between the dimmer and the LED illumination lamp. Thereby, the electric (four) shape of the deformed wire output from the phase control mode is corrected, thereby preventing the intermittent flashing of the LED illumination lamp. Also, you can use the wall money type dimmer switch as a dimmer. In this case, the brightness of all the lamps connected to the wall-embedded dimmer switch can be adjusted at the same time. Fig. 7 shows the appearance of an embodiment of a wall-embedded dimmer switch. Fig. 7(4) shows that the sliding type '11 7(b) is a rotary type. In the dimming switches, the main power supply 〇n/〇ff' can be switched by the power switch 75 and the output voltage can be adjusted by the slide type dimming button 71 or the rotary type dimming button 72. The dimming button can be of a type capable of continuously adjusting the output voltage, or a type capable of intermittently adjusting the output voltage in the range of 2 to 6 stages. Furthermore, the power switch of the wall-mounted dimmer switch shown in Fig. 7 is separately provided from the dimming button, but it can also be a dual-purpose type in which the adjusting button has the function of a power switch. Also, it can be a remote-mounted wall-mounted dimmer switch.

If the LED illuminator has a built-in dimmer, the brightness of the LED illuminator can be adjusted independently even when a plurality of LED illuminators are provided, so that the entire room can be adjusted to a fixed brightness. The output voltage from the dimmer can be adjusted by setting an adjustment button on the LED 101112438 17 201245619 illumination, or can be adjusted by remote control, or automatically according to the illumination measured by the illuminance sensor as follows. Adjustment. When a dimmer is built in the LED illuminator, dimming can be performed without using a wall-mounted dimmer switch, or both can be used together.
