Description
Technical field
The utility model belongs to technical field of semiconductor illumination, specifically refers to a kind of high aobvious finger LED lamp.
Background technology
The reducing power of light source to object color is called colour rendering, and colour rendering adopts colour rendering index (CRI) to characterize, and is the important indicator evaluating lighting source.The height of color rendition index, represents the degree of object " variable color " and " distortion " under this light source, and the light source that colour rendering index (CRI) is high is stronger to the reducing power of object color, shows closer to object color table under natural daylight.In colorimetry using black matrix (daylight) or standard illuminants D as with reference to light source, its colour rendering index is defined as 100.Such light source has more complete, even, continuous spectrum.When certain section of wavelength radiation power in light source light spectrum seldom or disappearance, illuminated object reverberation color can produce obvious gamut, and aberration can be very large, and the colour rendering index of light source will be very low.
At present, the white light LEDs major part that market uses uses blue chip to excite this traditional mode of yellow fluorescent powder to obtain, and the white light obtained is the result of blue light and green-yellow light mixed light in fact.But the spectrum obtained by blue-light excited green-yellow light, spectral component is relatively less, and the colour rendering index of mixing light is relatively low, generally can not more than 80.Simultaneously due to red color light component disappearance in spectrum, the R9 evaluated for redness in colour rendering index appraisement system can be very low.So the colour rendering index of LED entirety will be promoted, red color light component need be increased in spectrum.
Current LED factory generally adds red fluorescence powder in the led to make the aobvious LED product referred to of low colour temperature height.Red fluorescence powder is generally sulfide rouge and powder or nitride rouge and powder.But sulfide rouge and powder is because unstable chemcial property is easy and encapsulating material chemically reactive; Although the chemical property of nitride rouge and powder is stablized, because its excitation spectrum covers almost whole yellow green wave band, cause final white light efficiency to decline, be difficult to effectively meet practical application.
Summary of the invention
The utility model is solve existing LED lamp to show the not high problem of finger, proposes a kind of novel height aobvious finger LED lamp.
For solving the problem, the technical scheme that the utility model is taked is: a kind of high aobvious finger LED lamp, comprises fin, lamp plate, spring support, reflector, case ring and LED light source; Described LED light source is fixed on lamp plate, and lamp plate is mounted on fin surface, and described reflector is fixing on a heat sink, and spring support symmetry is arranged on reflector; Described case ring is connected with reflector; Described LED light source comprises white light LEDs, red-light LED and green light LED.
Preferably, the luminous flux ratio of described white light LEDs, red-light LED and green light LED is (6 ~ 8): 1:(0.8 ~ 1.4).
Preferably, high aobvious finger LED lamp also comprises blue-ray LED.
Preferably, the peak wavelength of blue-ray LED is 460nm ~ 485nm, adds the long-wave band blue light ingredient that long-wave band blue light can supplement the disappearance in LED lamp spectrum, greatly improves the colour rendering index of light fixture.
Preferably, the height adding blue-ray LED shows and refers to that the colour rendering index of LED lamp is up to more than 95.
Preferably, described height is aobvious refers to that LED lamp also comprises optical mixing cover, is mixed by LED modules with different colors light source, makes light fixture bright dipping more even.
The beneficial effect that the utility model obtains is: the height that the utility model provides is aobvious refers to that LED lamp uses conventional LED, by the luminous flux proportioning of LED modules with different colors, greatly improves the colour rendering index of LED lamp, reduces production cost; Only need LED common on market just can make high aobvious finger LED lamp, decrease and make the high aobvious restriction referred in LED lamp chip, packaging technology, can realize at lamp applications end.Make LED downstream and LED lamp application end exploitation height aobvious finger light fixture have more independence, do not need to depend on upstream chip and encapsulation, greatly reduce high aobvious finger light fixture development cost simultaneously; High aobvious finger LED lamp colour rendering index is up to more than 95, and structure is simple, easy to make, with low cost, is convenient to promote.
