The side of nearly incident light source 20 starts to be gradually increased to the side far from incident light source 20, the leaded light far from 20 side of incident light source
Dot density is greater than the light directing site density close to 20 side of incident light source, and the top surface of light guide plate 10, which is equipped with, absorbs photochromic layer 12,
One side end face of light guide plate 10 is externally provided with incident light source 20, and incident light source 20 includes visible light source 21 and UV light source 22, it is seen that light
Source 21 issues visible light and provides illuminating effect, and UV light source 22 issues UV light and adjusts the light transmittance for absorbing photochromic layer 12, in visible light
In the case that source 21 works, the working condition for adjusting UV light source 22 can adjust the illumination effect of Integral flat-plate lighting system.
The absorption photochromic layer 12 that can adjust visible-light absorptivity is arranged in the utility model, in UV light irradiation absorption photochromic layer
In the case where 12, the light transmittance for absorbing photochromic layer 12 will decline, so that stop portions visible light passes through, and absorb photochromic layer 12
Light transmittance be gradually increased along UV light direction of illumination, be capable of forming the dimming effect of gradual change；Photochromic layer 12 is absorbed after losing UV light
Original sufficiently large light transmittance can be restored to, it is seen that light can pass through unobstructedly；Leaded light need to be only arranged in light source
One end of plate 10 just can be realized the luminance dynamic adjustable function of visible light.
In the present embodiment, absorbing photochromic layer 12 is UV sensitization discoloration material layer, and UV sensitization discoloration material is absorbing UV light
Afterwards, the variation that can generate color is restored to original color after losing the irradiation of UV light.
Based on the above embodiment, absorbing photochromic layer 12 is silver halide photochromic layer, and the small silver halide of thickness is under normal circumstances
Close to clear, colorless, after the irradiation of UV light, silver halide will be decomposed into the silver-colored microparticle of many black, stops light to pass through, will lead
The light transmittance for absorbing photochromic layer 12 is caused to reduce, after losing the irradiation of UV light, silver and halogen will regroup, silver halide is generated, from
And the light transmittance for ensuring to absorb photochromic layer 12 restores normal, light, which can pass through, absorbs photochromic layer 12.
