Technical field

The present invention relates to a kind of lighting device, especially relate to the device that one comprises one or more solid-state light emitters and one or more luminescent phosphors (such as, one or more phosphors).The invention still further relates to a kind of means of illumination.

Background technology

In the U.S., there is the electricity of most every year for illumination (some assessment shows that electric consumption on lighting is up to 25% of whole electricity).Therefore, the lighting device keeping punching to provide a kind of efficiency higher is necessary.As everyone knows, incandescent lamp is the light source that efficiency is very low---the distributing as heat as heat energy instead of convert luminous energy to of the electricity that they consume nearly 90%.Wanting high (being approximately its 4 times) of the Energy Efficiency Ratio incandescent lamp of fluorescent light, but compared to the solid-state light emitters of such as light emitting diode and so on, the efficiency of fluorescent light is still very low.

In addition, compared to the ordinary life of solid-state light emitters, the life-span of incandescent lamp is relatively short, and namely its life-span is generally about is 750-1000 hour.Comparatively speaking, such as, the life-span of light emitting diode generally can in 10 years.The life-span of fluorescent light is longer than incandescent lamp (such as, 10000-20000 hour), but the colour rendering of light that fluorescent light sends will differ from.

Color rendition typical case uses colour rendering index (CRI Ra) to measure.CRI Ra is the colour developing of an illuminator is relative measurement how relative to the colour developing of a reference illumination device (light source).For the colour temperature lower than 5,000K, use blackbody radiator, and for more than 5, the colour temperature of 000K, then use a series of frequency spectrum defined by CIE (International Commission on Illumination).The mean value of the deviation of the surface color and polish of CRI Ra when to be an object thrown light on by this reference light source relative to this object by surface color and polish during a specific lamp illumination.If the chromaticity coordinates of thrown light on by this illuminator one group of test color with by this reference radiation the coordinate of identical test color that irradiates identical time, then CRI Ra equals 100.Daylight has high CRI (Ra is approximately 100), and wherein incandescent lamp bulb is also quite close to (Ra is greater than 95), and the illumination of fluorescence more inaccurate (being typically the Ra of 70-80).The dedicated illumination of some type have low-down CRI (such as, mercury vapor lamp or sodium vapor lamp have be low to moderate about 40 or even lower Ra).Such as, sodium vapor lamp is used for the highway that throws light on, but, reaction time of driving along with CRI value lower, significantly reduce (for any specific brightness, legibility reduces along with CRI reduction).

Another problem that conventional illuminator faces needs periodically to change lighting device (as bulb etc.).When changing the very high occasion of lighting device costs close to the very difficult occasion (as domed ceiling, bridge, pile, traffic track) of light fixture and/or some, this problem is seeming particularly outstanding.The life-span of conventional illuminator is generally about is 20 years, and corresponding luminaire uses at least 44000 hours (using 6 hours based on every day in 20 years).Light-producing device lifetime is general shorter, so that needs periodically to change.

Therefore, due to like this, making great efforts development always and using solid-state light emitters to replace incandescent lamp, fluorescent light and other luminaires and the method making it be used widely.In addition, at those in the place using solid-state light emitters (light emitting diode), people are making great efforts to improve its efficiency, colour rendering (CRI), light efficiency (lm/w) and/or serviceable life.

Light emitting diode is the well-known semiconductor equipment that electric energy can be converted to luminous energy.Various light emitting diode is applied in due to the application target constantly expanded in ever-increasing multiple fields.

More particularly, light emitting diode is semiconductor equipment, and when producing electric potential difference between p-n joint structure, it can luminescence (as ultraviolet light, visible ray, infrared light).There is the method for many famous manufacture light emitting diodes and dependency structure thereof, the equipment that the present invention can adopt any one such.Such as, in the 12-14 chapter of " physical characteristics of semiconductor equipment " (second edition in 1981) and modern semiconductor devices physical characteristics the 7th chapter (version in 1998) in a large amount of optical devices of describing, comprise light emitting diode (Chapters 12-14of Sze, Physics of Semiconductor Devices, (2d Ed.1981) and Chapter 7of Sze, Modern Semiconductor Device Physics (1998)).

Those are usually known and " LED " that sell in (such as) e-shop typically refers to packaging part (packaged) equipment be made up of a large amount of element.These packaging part equipment comprise the semiconductor based on light emitting diode, such as (but being not limited to) the patent No. be 4918487, the packaging part of various terminal disclosed in the United States Patent (USP) of 5631190 and 5912477 and the whole light emitting diode of packaging part.

As everyone knows, light emitting diode produces light by excitation electron through the band gap between the conduction band of active layer (both luminescent layer) of semiconductor and valence band.The wavelength of the light that electronic transition produces depends on band gap energy level.Therefore, the color of light that light emitting diode sends depends on the semiconductor material of the active layer of light emitting diode.

Although the development of light emitting diode is reformed illuminating industry in a lot, some characteristics still Challenge of light emitting diode, wherein part characteristic is also not fully developed.Such as, the wavelength of the light that any specific light emitting diode sends normally single wavelength (it depends on the composition and structure of light emitting diode, this single wavelength is applicable to some application, but be not suitable for other application, (such as, when being applied in illumination, such luminescent spectrum has low-down CRI)).

Because the light of the light being perceived as white light necessarily two or more colors (or wavelength) mixes, single light emitting diode is not had to send white light.Now produce " in vain " the optical diode lamp with the light-emitting diode pixel formed by each red, green and blue optical diode.The generation of other " in vain " light emitting diode is the luminescent material (as phosphor) that the light emitting diode (2) producing blue light by comprising (1) sends gold-tinted, described gold-tinted is that the optical excitation luminescent phosphor sent by described light emitting diode produces, then, blue light and yellow light mix just obtain the white light of institute's perception.

In addition, all know in this area and other field, primary colors is mixed to get the mixing principle of non-primary colors.Generally, the CIE chromaticity diagram of version in the 1931 (CIE chromaticity diagram of (international standard for primary colors set up for 1931) and version in 1976 (similar with version in 1931, but revise, make distance similar on figure represent similar color-aware difference) provide a kind of useful reference being used for defining the mixed color of differentiation primitive color.

Light emitting diode can be single or the carrying out of combination apply, also can select to mix the color that one or more luminescent materials (as phosphor or scintillator and/or light filter) produce any required perception.Therefore, people are making great efforts to replace existing light source with light emitting diode as light source, thus carry out modification as its efficiency, colour rendering index (CRI), light efficiency (lm/w) and/or serviceable life, and be not limited to the color of certain color any or mixed light.

Person skilled in art knows and can obtain a large amount of various luminescent materials and (is also luminescent phosphor (lumiphor) or luminous medium (luminophoric media), announce as the patent No. United States Patent (USP) that is 6600175, quote in full with for referencial use at this).Such as, phosphor is a kind of luminescent material that will send corresponding radiation (as visible ray) when being subject to excitation light source excites.In a lot of example, the wavelength of corresponding radiation is different from the wavelength of described excitation source.Other luminescent material comprises scintillator, dayglow light belt and send the ink of visible ray under UV-irradiation.

Luminescent material can be categorized into frequency reducing (down-converting), namely by photon transport to lower level (longer wavelength), or raising frequency (up-converting), namely by photon transport to higher energy level (shorter wavelength).

As mentioned above, luminescent material in LED device be by luminescent material is joined clear encapsulant material discussed above (as, material based on epoxy resin, based on silica gel or based on glass) innerly to obtain, such as, by mixing or spraying method.

Such as, the patent No. be 6963166 the U.S. (Yano ' 166) disclose a kind of traditional light emitting diode bulb, it comprises light-emitting diode chip for backlight unit, the bullet-headed transparent shell of covering luminousing diode chip, to the wire that light-emitting diode chip for backlight unit is powered, the light sent by light-emitting diode chip for backlight unit reflexes to unidirectional reflector, wherein, adopt light-emitting diode chip for backlight unit described in the first resin portion packaging part, then adopt the further packaging part of the second resin component.According to Yano ' 166, described first resin portion is by filling reflector with resin material, on the bottom of then light-emitting diode chip for backlight unit being installed reflector, then the negative electrode of light emitting diode and anode electric wire are carried out being electrically connected with described wire and obtaining of solidifying.According to Yano ' 166, phosphor is dispersed in the first resin portion, so that excited by the light A that light-emitting diode chip for backlight unit sends, the phosphor be excited will produce the light (light B) longer than light A wavelength, a part of light A is through the first resin part comprising phosphor, then, the light C that light A and light B is mixed to get just can be used to throw light on.

As mentioned above, research shows that " white LED lamp " (namely, be perceived as white light or be approximately the light of white light) can be used as the potential substitute of white incandescent lamp.Typical white LED lamp comprises the blue LED die of packaging part, and it can be made up of the gallium nitride (GaN) being coated with phosphor, such as yttrium aluminum garnet.In this LED, the wavelength of the light that blue led chips produces is approximately 450nm, and the peak wavelength of the gold-tinted that phosphor produces is approximately 550nm after receiving this excitation line.Such as, in part design, white light LEDs is that the method by coating ceramic fluorescent layer at the outside surface of blue-ray LED semiconductor is formed.A part for the blue light sent from light emitting diode is through phosphor, and some blue light is absorbed by phosphor, and described phosphor is excited and sends gold-tinted.Through the yellow light mix that phosphor and unabsorbed part blue light and phosphor inspire in the blue light that light emitting diode sends, the light of this blue light of people's perception and yellow light mix is white light.

Or as mentioned above, in another kind of LED, the LED chip sending ultraviolet light with send red (R), green (G), the phosphor material of indigo plant (B) light combines.Inner in this " RGB LED ", the ultraviolet excitation phosphor sent from light-emitting diode chip for backlight unit, makes phosphor send red, green and blue light, and when after the mixing of these light, the mixed light that human eye is seen is exactly white light.Therefore, the white light of the mixed light as three kinds of light can be obtained.

There is now design LED encapsulation piece and other electronic component are assembled in a light fixture.In this design, LED encapsulation piece is placed on circuit boards or is directly installed on heat radiator, and this circuit board is mounted on a heat radiator, then this heat radiator is installed to light fixture together with required driving electronic component.In several cases, additional optics (being only second to package element) is also needed.

The light source replacing other with LED (such as, incandescent lamp) time, the LED that packaging part is good has been used in traditional light-emitting device, such as, the device of the substrate including hollow lens and be connected with hollow lens, described substrate contains traditional Socket casing (socket housing), and described Socket casing has one or more contact be connected with power electric.Such as, LED bulb can be built like this, make it comprise a circuit board, be assemblied in the multiple packaging part LED on described circuit board and be connected with described circuit board and be applicable to the joint pin that is connected with the Socket casing of light fixture.Therefore described a large amount of LED can by power drives.

Nowadays, in various application widely, in order to obtain white light, and in order to possess higher efficiency, higher colour rendering index (CRI), better contrast, better light efficiency and longer life-span, still need modification as the use of the solid-state light emitters of light emitting diode.

In order to obtain higher energy efficiency, the colour rendering index (CRI) of improvement, the effect (lm/W) improved, low cost and/or longer life-span, utilize solid-state light emitters (i.e. light emitting diode) in more diversified application, provide the mode of white light to have continual demand.

Part so-called " warm white " LED has for more suitably temperature (being generally 2700-3500K) the use of indoor, and in some embodiments, there is good CRI (Ra is up to 95 in the example that yellow and red-emitting phosphor mix), but its light efficiency is at half than the white light LEDs of standard above.

The color body that RGB LED illuminates does not present with its realistic colour sometimes.Such as, the object of an only reflect yellow, and therefore presenting yellow with during white light, and when the obvious yellow light produced with the ruddiness and green light LED with a RGB LED lamp, may present unsaturated and grizzly.Therefore, this lamp is considered to provide splendid colour rendering, time especially when illumination different set (such as, in general illumination) and in particular to natural scene.In addition, the efficiency of current available green light LED is on duty mutually, because which limit the efficiency of this lamp.

Adopt the LED with the tone of many types also can need to use the LED with various efficiency similarly, it comprises the LED of some poor efficiency, thus reduce the efficiency of this system, and add circuit complexity and the cost of the color balance controlling many dissimilar LED and maintain lamp significantly.

Chromaticity coordinate (that is, color dot) along black body locus follows planck formula: E (λ)=A λ ^-5/ (e ^(B/T)-1), wherein E is radiation intensity, and λ is radiation wavelength, and T is black body color temperature, and A and B is constant.The chromaticity coordinates be positioned on black body locus or near black body locus produces white light comparatively comfortable for human viewer.This 1976CIE figure comprises the temperature tabular along black body locus.These temperature tabulars show one makes its color pathway being increased to the blackbody radiator of this temperature.Object after heating when one becomes white heat, then first it send ruddiness, then gold-tinted, then white light, and be finally blue light.Why this is shorten gradually because of increasing along with temperature with the wavelength be associated of the peak of radiation of blackbody radiator, and this is consistent with Wien (Wien) displacement law.Therefore, the luminophor produced on black body locus or near the light of black body locus can be described by its colour temperature.

Being depicted in equally, 1976CIE figure is label A, B, C, D and E, and these labels are the corresponding light of luminophor generation of several standards being indicated as being luminophor A, B, C, D and E respectively.

The amended mean value of CRI Ra to be the colour developing of the colour developing of illuminator when penetrating with eight reference color color pictures relative to a reference radiation be relative measurement how.If when the chromaticity coordinates of irradiated by this illuminator one group of test color is with by the coordinate of this blackbody radiator radiation same test look identical, then this CRIRa equals 100.
