Description
Technical field
The utility model relates to field of LED illumination, relates to a kind of LED light source and LED specifically.
Background technology
LED or in general LED illumination device are well known in the art, and are nowadays usually used in diversified illumination application.Except size aspect is very small-sized, so-called high-capacity LED also provides high light flux and very energy-conservation.
Along with the permeability of LED illumination product in people's daily life strengthens, range of application is more and more extensive, and people are for illumination, and particularly the light source of room lighting there has also been new requirement.For indoor illumination light fitting, not only will obtain good illuminating effect, also to the comfort level of illumination, color rendering has had further requirement, thus on light-source encapsulation, just needs the colour rendering index promoting light source.LED has that volume is little, power consumption is low, long service life, environmental advantages, is more and more widely used in the illumination in each place.The white light that existing blue light wafer collocation fluorescent material is made, colour rendering index is at 65-80, and the white-light illuminating product colour rendering index that such as place such as museum, the Art Museum needs is greater than 90.In the white-light spectrum that blue light wafer collocation fluorescent material is made, red spectrum is fewer, and colour rendering index is at 65-80.
The method being produced white light by normal LED chip mainly contains following three kinds:
(1) blue-light LED chip+YAG yellow fluorescent powder.Utilize GaN base blue-light LED chip to excite YAG fluorescent powder to send gold-tinted, produce white light with remaining blue light.By regulating and controlling the intensity of blue light and gold-tinted, the white light of different-colour can be produced.This scheme realizing white light, product and manufacture craft are relatively simple, and technology is tending towards ripe, and achieving commercialization, is the mainstream technology manufacturing white light LEDs at present.But the white light that this scheme produces can only be fixing colour temperature, and general colour rendering index Ra only has 60 ~ 80 usually, and special colour rendering index R9 is also very low, meeting that R9 is on the low side makes the color of object become dim.
(2) near ultraviolet LED chip+RGB fluorescent material.The ultraviolet utilizing near ultraviolet LED chip to send excites RGB fluorescent material synthesize white light.Change photochromic by the proportioning adjusting fluorescent material, obtain required white light, and good colour temperature and development index can be obtained, but near ultraviolet LED chip applicatory not yet forms ripe application.
(3) R, G, B three primary colours synthesize white light.By R, G, B three-primary color LED chip package in individual devices, by regulating the drive current of three kinds of color chips to change the proportioning of three kinds of coloured light respectively, the light of shades of colour can be obtained, the white light of broad band can also be obtained.But under this method, the more difficult light distribution scheme determining LED chip, is particularly difficult to the light distribution scheme determining to obtain having excellent fit light effect.So-called good light distribution effect, refers in wide scope, to realize adjustable color in (2700 ~ 6500K), and can keep high colour rendering index within the scope of this.
Therefore, how solving the problem is technical problem urgently to be resolved hurrily in the industry.
