Technical field

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

Background technology

In the U.S., have every year most electric weight be used for illumination (some assessment show electric consumption on lighting up to whole electric weight 25%).Therefore, be necessary to keep punching and provide a kind of efficiency higher lighting device.As everyone knows, incandescent lamp is the very low light source of efficiency---they consumed electric nearly 90% distribute rather than convert to luminous energy as heat as heat energy.The wanting of the Energy Efficiency Ratio incandescent lamp of fluorescent lamp high (approximately being its 4 times), but than the solid-state light emitters of for example light emitting diode and so on, the efficiency of fluorescent lamp is still very low.

In addition, than the ordinary life of solid-state light emitters, the life-span of incandescent lamp is shorter relatively, just its life-span general about be 750-1000 hour.Comparatively speaking, for example, the life-span of light emitting diode generally can be in 10 years.The life-span of fluorescent lamp is than incandescent lamp long (for example, 10000-20000 hour), but the colour rendering of the light that fluorescent lamp sends will differ from.

The color rendition typical case is to use colour rendering index (CRI Ra) to measure.CRI Ra is that the colour developing of an illuminator is relative measurement value how with respect to the colour developing of a reference illumination device (light source).For being lower than 5, the colour temperature of 000K is used blackbody radiator, and for surpassing 5, the colour temperature of 000K is then used a series of by the defined frequency spectrum of CIE (International Commission on Illumination).The mean value of the deviation of the surface color and polish during by this reference light source illumination of the surface color and polish when CRI Ra is an object by a specific lamp illumination with respect to this object.If when the chromaticity coordinates of one group of test color of being thrown light on by this illuminator was identical with the coordinate of the identical test color of being shone by this reference radiation, then CRI Ra equaled 100.Daylight has high CRI (Ra approximately is 100), and wherein incandescent lamp bulb also is quite approaching (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 (for example, mercury vapor lamp or sodium vapor lamp have be low to moderate about 40 or even lower Ra).For example, sodium vapor lamp is used for the highway that throws light on, yet the reaction time of driving is significantly reduced (for any specific brightness, legibility reduces along with the CRI reduction) along with the CRI value is low more.

Another problem that conventional illuminator faces is to need the periodic lighting device (like bulb etc.) of changing.When near light fixture very occasion (like domed ceiling, bridge, pile, traffic track) and/or some of difficulty change the very high occasion of lighting device costs, it is particularly outstanding that this problem seems.The life-span of conventional illuminator general about be 20 years, corresponding luminaire uses at least 44000 hours (based on using 6 hours every day in 20 years).The luminaire life-span is generally shorter, so that needs periodic the replacing.

Therefore, owing to suchlike reason, making great efforts the method that development uses solid-state light emitters to replace incandescent lamp, fluorescent lamp and other luminaires and it is used widely always.In addition, in the place of 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 service life at those.

Light emitting diode is the well-known semiconductor equipment that can convert electric energy into luminous energy.Various light emitting diodes are owing to the application target that constantly enlarges is applied in the ever-increasing multiple field.

More particularly, light emitting diode is a semiconductor equipment, and when producing electrical potential difference between the p-n joint structure, it can luminous (like ultraviolet light, visible light, infrared light).The many famous manufacturing light emitting diodes and the method for dependency structure thereof are arranged, and the present invention can adopt any such equipment.A large amount of optical devices of describing in the 7th chapter of (second edition in 1981) and modern semiconductor devices physical characteristic (version in 1998) for example in the 12-14 chapter of " physical characteristic of semiconductor equipment "; 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 common that know and " LED " that in (for example) e-shop, sell typically refer to packaging part (packaged) equipment of forming by a large amount of elements.These packaging part equipment comprise the semiconductor based on light emitting diode, and for example (but being not limited to) is the packaging part of disclosed various terminals and the whole light emitting diode of packaging part in 4918487,5631190 and 5912477 the United States Patent (USP) in the patent No..

As everyone knows, light emitting diode be through excitation electron pass semi-conductive active layer (both luminescent layers) conduction band and the band gap between valence band produce light.The light wavelength that electron transition produces depends on the band gap energy level.Therefore, the color of the light that sends of light emitting diode depends on the semi-conducting material of the active layer of light emitting diode.

Although the development of light emitting diode illumination industry aspect is much reformed, some characteristics of light emitting diode still are faced with challenge, and wherein partly characteristic is not also developed fully.For example; The light wavelength that any specific light emitting diode sends normally single wavelength (it depends on the composition and the structure of light emitting diode; This single wavelength is fit to some application; But be not suitable for other application; (for example; When being applied in illumination, such luminescent spectrum has low-down CRI)).

Mix because be perceived as the light of white light and must be the light of two kinds or more colors (or wavelength), do not have single light emitting diode can send white light.Produced " in vain " the optical diode lamp that has by the light-emitting diode pixel that each is red, green and blue light diode forms at present.The generation of other " in vain " light emitting diode is the luminescent material (like phosphor) that sends gold-tinted through the light emitting diode (2) that comprises (1) generation blue light; Said gold-tinted is to be produced by the optical excitation luminescent phosphor that said light emitting diode sends; Then, blue light and yellow light mix have just obtained the white light of institute's perception.

In addition, know all that the former mixture of colours obtains the mixing principle of non-primary colors in this area and other field.Generally; The XYZ chromaticity diagram of version in the 1931 (XYZ chromaticity diagram of (international standard that is used for primary colors of being set up in 1931) and version in 1976 (similar with version in 1931; But revise, make that similar distance has been represented the difference of similar color-aware on figure) a kind of useful reference of distinguishing the mixed color of primitive color that is used for defining is provided.

Light emitting diode can be single or the using of combination, also can select to mix the color that one or more luminescent materials (like phosphor or scintillator and/or filter) produce any required perception.Therefore, people are making great efforts to replace conventional lighting sources with light emitting diode as light source, thereby improve for example its efficiency, colour rendering index (CRI), light efficiency (lm/w) and/or service life, and are not limited to the color of any certain color or mixed light.

The person skilled in art knows and can access a large amount of various luminescent materials and (also is luminescent phosphor (lumiphor) or luminous media (luminophoric media); As the patent No. is that 6600175 United States Patent (USP) is announced, quotes in full with for referencial use at this).For example, phosphor is a kind of luminescent material that when receiving excitation light source excites, will send corresponding radiation (like visible light).In a lot of examples, the wavelength of corresponding radiation is different with the wavelength of said excitation source.Other luminescent material comprises scintillator, dayglow light belt and the printing ink that under UV-irradiation, sends visible light.

Luminescent material can be categorized into frequency reducing (down-converting), just photon transport be arrived than low-lying level (longer wavelength), or raising frequency (up-converting), just photon transport is arrived higher energy level (shorter wavelength).

As stated; Luminescent material in the LED equipment be through luminescent material is joined transparent enclosure part material discussed above (as; With epoxy resin be main, be main with silica gel or be main material with glass) lining obtains, for example, through mixing or spraying method.

For example; The patent No. is that U.S. (Yano ' 166) of 6963166 has announced 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 lead of light-emitting diode chip for backlight unit power supply, the light that light-emitting diode chip for backlight unit is sent reflexes to unidirectional reflector, wherein; Adopt first resin portion to divide packaging part said light-emitting diode chip for backlight unit, adopt the further packaging part of second resin component again.According to Yano ' 166; Said first resin partly is through filling reflector with resin material; Then light-emitting diode chip for backlight unit is installed on the bottom of reflector, again the negative electrode of light emitting diode and anode are electrically connected with said lead with electric wire and obtaining of solidifying.According to Yano ' 166; Phosphor is dispersed in the first resin part; So that the light A that is sent by light-emitting diode chip for backlight unit excites; The phosphor that is excited will produce the light longer than light A wavelength (light B); The part of light A is passed first resin part that comprises phosphor; Then, light A mix with light B the light C that obtains just can be used to the illumination.

As stated, research shows that " white LED lamp " (just, 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 chip of packaging part, and it can be processed by the gallium nitride that is coated with phosphor (GaN), such as yttrium-aluminium-garnet.In this LED lamp, the light wavelength that blue led chips produces is approximately 450nm, and the peak wavelength of the gold-tinted that phosphor produces after receiving this excitation line approximately is 550nm.For example, in partly designing, white light LEDs is to form through the method for coating ceramic fluorescence coating at the semi-conductive outer surface of blue-ray LED.The part of the blue light that sends from light emitting diode is passed phosphor, and the part blue light absorbed by phosphor, and said phosphor is excited and sends gold-tinted.Pass the yellow light mix that phosphor and unabsorbed that part of 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.

Still as stated, in another kind of LED lamp, the led chip that sends ultraviolet light combines with the phosphor material that sends red (R), green (G), blue (B) light.In this " RGB LED lamp " lining, the ultraviolet excitation phosphor that sends in the light-emitting diode chip for backlight unit makes phosphor send red, green and blue light, and after these light mixed, the mixed light that human eye is seen was exactly a white light.Therefore, can obtain white light as the mixed light of three kinds of light.

Have now LED packaging part and other electronic component are assembled in a design in the light fixture.In this design, the LED packaging part is positioned on the circuit board or is directly installed on the fin, and this circuit board is mounted on the fin, again this fin is installed to light fixture with required driving electronic component.Under multiple situation, also need additional optics (being only second to package element).

The light source that replaces other with LED (for example; Incandescent lamp) time; The LED that packaging part is good has been used in traditional light-emitting device; For example; Include the device of hollow lens and the substrate that links to each other with hollow lens; Said substrate contains traditional Socket casing (socket housing), and said Socket casing has one or more contacts that are electrically connected with power supply.For example, can make up the LED bulb like this, make it comprise a circuit board, be assemblied in a plurality of packaging part LED and the joint pin that links to each other with said circuit board and be fit to link to each other on the said circuit board with the Socket casing of light fixture.Therefore said a large amount of LED can be 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 improve the for example use of the solid-state light emitters of light emitting diode.

For the effect (lm/W) that obtains higher energy efficiency, the colour rendering index of improvement (CRI), improvement, low-cost and/or longer life-span, utilize solid-state light emitters (being light emitting diode) in more diversified application, to provide the mode of white light that continual demand is arranged.

Summary of the invention

Existing white LED light source is efficient relatively but have lower colour rendering index, and Ra generally is lower than 75, and is poor especially to the demonstration of redness, and especially poor to the demonstration of green.This means with adopting incandescent lamp or natural lighting and compare that many things comprise that the general human colour of skin, food, label, drawing, placard, symbol, dress ornament, home decoration, plant, flower, automobile etc. will demonstrate variegated or wrong color.Usually, the colour temperature of such white light LEDs is about 5000K, though this illumination to commodity production or advertisement and printing material is comparatively desirable, for general lighting, such temperature is unaccommodated.

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

The color body that RGB LED lamp illuminates does not appear with its realistic colour sometimes.For example, object of reflect yellow only, and therefore with white light the time, present yellow, and, possibly appear unsaturated and grizzly when having ruddiness and green light LED were produced the tangible gold-tinted irradiation of a RGB LED light fixture.Therefore, this lamp is considered to the colour rendering that can not provide splendid, during especially when illumination different set (for example, in general illumination) and in particular to natural scene.In addition, the efficient of present available green light LED is on duty mutually, has therefore limited the efficient of this lamp.

The LED that employing has the tone of many types also can need use the LED with various efficient similarly; It comprises some inefficient LED; Thereby reduced the efficient of this system, and increased circuit complexity and the cost of controlling many dissimilar LED and keeping the color balance of lamp significantly.
