Description
Technical field
The present invention relates to lighting devices, more specifically, it relates to a kind of area source.
Background technique
With the development of science and technology, people's illuminator used in everyday is developed based on incandescent lamp as three primary colours fluorescence
Lamp and LED illuminator, in which:
Incandescent lamp: because incandescent lamp utilizes metal tungsten wire electrified light emitting, linear light source shines, (low color temperature) based on yellow light, light
Spectrum group is combined into RGB composition composition.When luminous flux reaches certain value, because linear light source light-emitting area is small, will cause more serious
Glare phenomenon.
Three-color fluorescent lamp: by exciting fluorescent tube mercury vapor body to excite painting 220v alternating current rectifier ultraviolet light high pressure
The three primary colors fluorescent powder (red, green, blue) of tube inner wall is overlayed on, white light source is formed, spectral combination is RGB composition composition, but
Its light radiation harm is big, and dazzle is severe, and photobio logical hazard is larger, and blue ray radiation is higher.
LED illumination lamp excites blue chip to issue blue light and recycles the painting of this blue light deexcitation by constant-current driving power supply
The LED yellow fluorescent powder overlayed on blue chip issues yellow light, and blue yellow excitation forms white light source, and spectral combination is RGB
Composition, but because of its blue light excitation principle, therefore it is also easy to produce rich blue light phenomenon and the smaller generation point light source light-emitting of LED chip area, therefore
Its glare phenomenon is more serious.
By the understanding to above-mentioned incandescent lamp, three-color fluorescent lamp, LED illumination lamp principle of luminosity, exist obviously not
Foot place is glare phenomenon, the excessively high phenomenon of photobio logical hazard value.
Summary of the invention
In view of the deficienciess of the prior art, the invention reside in a kind of area source is provided, the area source photobio logical hazard value
Low (blue ray radiation intensity is low, the hot harm value of retina is low), dazzle value is low, and visual comfort is good.
To achieve the above object, it the present invention provides the following technical scheme that a kind of area source, including pedestal, lampshade and sets
The white emitter in lampshade is set, the inside of the lampshade is equipped with yellow fluorescence film, yellow described in component in parts by weight
Fluorescent film include 0.1% ~ 1.5% yellow fluorescent powder, 10% ~ 20% diffusion master batch and 78.5% ~ 89.9% transparent engineering plastic
Grain, partial size≤4um of the yellow fluorescent powder.
By using above-mentioned technical proposal, when white light source passes through yellow fluorescence film, the blue light components in white light swash
Nanoscale yellow fluorescent powder, which issues some blue light in yellow light and white light source and combines, in jaundice color fluorescent film forms white light, then and
White light source forms recombined white light, by exciting to blue light in white light, to effectively change energy balance in former white light, effectively drops
Low photobio logical hazard index value is formed simultaneously yellow fluorescence film and shines, as the illuminator of surface source luminescence, effectively increases lamp
The luminous optical density of tool, is greatly reduced dazzle value, effectively increases visual comfort.
