車燈之LED發光模組LED light module

本創作係為一種應用在車輛大燈上的LED發光模組,尤指一種在無需更改車輛原有燈殼的情況下,可以直接取代傳統燈泡裝設在燈殼內的LED發光模組。The present invention is an LED lighting module applied to a vehicle headlight, especially an LED lighting module that can directly replace a conventional light bulb installed in a lamp housing without changing the original lamp housing of the vehicle.

LED燈因具有具有高亮度、體積小、使用壽命長、低耗電量等優點,被廣泛應用在照明領域中,例如使用在警示燈、交通號誌燈、大型廣告看板上,一般燈具主要是控制LED光源的明滅而產生方向燈或警示的效果,或是將LED燈陣列後以電路板進行時序控制而產生閃爍的廣告效果。LED lamps are widely used in the field of lighting because of their high brightness, small size, long service life and low power consumption. For example, they are used in warning lights, traffic lights, and large advertising billboards. Controlling the LED light source to produce a directional light or warning effect, or the LED light array is followed by a circuit board for timing control to produce a flickering advertising effect.

雖然LED燈取代傳統燈泡已成為趨勢,但車輛大燈仍以傳統的鹵素燈泡、氙氣燈泡為主,主要原因是車輛大燈的燈泡必須由內而外安裝在防水燈殼內,其功能需具備不同發光位置的遠燈及近燈,又高亮度LED燈容易因過熱而降低LED的亮度甚至損壞,相較於一般燈具在使用上仍有安全性的疑慮,使LED取代傳統燈泡仍有相當的困難度。Although LED lights have become a trend to replace traditional light bulbs, the main headlights of the vehicle are still traditional halogen bulbs and xenon bulbs. The main reason is that the bulbs of the headlights must be installed inside the waterproof lamp housing from the inside out. High-brightness LED lights with different illumination positions are easy to reduce the brightness or even damage of LEDs due to overheating. Compared with the general lamps, there are still some doubts about the safety of LEDs. Difficulty.

如第一圖所示,係為一車輛大燈所使用的傳統燈泡,其前端為一內部具有可切換遠燈及近燈不同發光位置的發光單元1,在發光單元1後方設有一用來固定在燈殼上的固定片2,固定片2後方則設有一可與車輛電源插頭插接的連接器3;其中,固定片2及連接器3的形狀會因為車輛廠牌而有不同規格,非僅侷限於圖中所示。As shown in the first figure, the conventional light bulb used in a vehicle headlight has a front end of the light-emitting unit 1 having a different light-emitting position for switching between the high-beam and the near-light, and a fixing unit is disposed behind the light-emitting unit 1 for fixing. The fixing piece 2 on the lamp housing is provided with a connector 3 which can be inserted into the power plug of the vehicle behind the fixing piece 2; wherein the shape of the fixing piece 2 and the connector 3 may have different specifications due to the vehicle label, It is limited to the one shown in the figure.

上述習知防水燈殼在殼內設有一具有聚光凹部的反射罩,該反射罩底部有容置孔,傳統燈泡從容置孔背面向前穿入反射罩中,使發光單元位在反射罩中心;當傳統燈泡發亮時,藉著聚光凹部進行聚光,再利用反射罩將光源投射而出,故發光單元上不同的發光位置會影響反射罩投 射出光線的角度,讓車輛大燈產生遠燈和近燈的功能。In the above-mentioned conventional waterproof lamp housing, a reflector having a condensing concave portion is disposed in the casing, and a bottom of the reflector has a receiving hole. The conventional bulb penetrates into the reflector from the back of the accommodating hole, so that the illuminating unit is located at the center of the reflector. When the conventional light bulb is bright, the light is concentrated by the condensing concave portion, and then the light source is projected by the reflector, so that different light-emitting positions on the light-emitting unit may affect the reflector The angle of the light is emitted, so that the headlights of the vehicle produce the functions of the high and low lights.

此外,如第二圖所示,為一市售使用在車輛大燈的LED發光模組,該發光模組背部具有可供散熱的散熱鰭片組4,在散熱鰭片組4前側為一焊接有LED陣列的片狀電路板5,片狀電路板5前方則設有一片用來導引光源的導光板6。In addition, as shown in the second figure, there is an LED lighting module commercially available for use in a vehicle headlight, the heat-emitting fin group 4 having heat dissipation on the back of the light-emitting module, and a welding on the front side of the heat-dissipating fin group 4 A chip circuit board 5 having an LED array, and a light guide plate 6 for guiding a light source is disposed in front of the chip board 5.

雖然上述LED發光模組在使用上能滿足基本的照明功能,但從圖示中可知,散熱鰭片組4佔據很大的體積,無法與原有燈殼相互配合,欲安裝在車輛大燈的燈殼時,需要技術人員修改整個防水燈殼的設計,相當耗時費工。再加上LED發光模組必須另外經驅動器驅動才能進行發光,因此還必須再預留空間供驅動器進行架設,使配合的燈殼必須另外生產製造;又車輛大燈的空間配置有限,裝設位置也接近引擎室,行車時容易造成LED發光模組散熱不易以及受引擎室高熱影響而增加故障機率。Although the above LED lighting module can meet the basic lighting function in use, it can be seen from the figure that the heat dissipation fin group 4 occupies a large volume and cannot cooperate with the original lamp housing, and is intended to be installed in the vehicle headlight. When the lamp housing is used, the technician needs to modify the design of the entire waterproof lamp housing, which is quite time-consuming and labor-intensive. In addition, the LED lighting module must be additionally driven by the driver to emit light, so it is necessary to reserve space for the driver to be erected, so that the matching lamp housing must be separately manufactured; and the space configuration of the vehicle headlight is limited, and the installation position is limited. It is also close to the engine room. It is easy to cause the LED light-emitting module to dissipate heat when driving, and it is affected by the high heat of the engine room to increase the probability of failure.

除了上述習知LED發光模組安裝上困難的問題以外,車輛大燈屬於耗材,若使用了特殊規格LED發光模組,下次欲更換時,就會造成相當大的困擾,致使消費者、技術人員甚至是車廠,採用該LED發光模組的意願皆因此而大為降低,使其使用對象只侷限在車輛重度改裝的消費者,顯然無法取代傳統燈泡供一般大眾使用,實屬可惜。In addition to the above-mentioned difficulties in the installation of conventional LED lighting modules, vehicle headlights are consumables. If a special specification LED lighting module is used, the next time you want to replace it, it will cause considerable trouble, causing consumers and technology. The personnel and even the car manufacturer, the willingness to adopt the LED lighting module is greatly reduced, so that the object of use is limited to the consumers of heavy modification of the vehicle, and it is obviously a pity that it cannot replace the traditional light bulb for the general public.

有鑑於此,本創作人乃累積多年相關領域的研究以及實務經驗,特創作出一種LED車燈構造,能有效將LED燈運作時所產生的廢熱釋放排出,並解決習知LED發光模組無法直接裝設在車輛原有燈殼上的缺失。In view of this, the creator has accumulated many years of research and practical experience in related fields, and created a LED lamp structure, which can effectively release the waste heat generated when the LED lamp is operated, and solve the problem that the conventional LED lighting module cannot be solved.
