The invention discloses a novel crystal clear lamp optical structure which comprises a decoration ring, a front light guide column arranged in the middle of the decoration ring, a light adjusting film arranged on the rear side of the front light guide column, a rear light guide column aligned with the front light guide column and arranged on the rear side of the light adjusting film, and a plurality of LED light sources arranged on the light inlet face of the rear side of the rear light guide column. The rear light guide column is sleeved with the dark grating; when the LED light source is not lightened and the dimming film is electrified, the dimming film is in a surface transparent state under the action of ordered arrangement of internal material molecules; when the LED light source is lightened and the dimming film is powered off, the dimming film has the surface semitransparent light uniformizing characteristic under the action of disordered arrangement of internal material molecules, and light rays emitted by the LED light source can enter the dimming film through the rear light guide column and then enter the dimming film to be subjected to diffuse reflection. The scheme that the dimming film is clamped between the double-layer thick-wall light guide columns is adopted, and the glittering and translucent effect when the lamp is not turned on and the uniform light-emitting effect at a larger angle when the lamp is turned on are achieved through power-on and power-off of the dimming film.
本发明公开了一种新型晶莹剔透灯具光学结构,它包括饰圈,设置于饰圈中间的前导光柱,设置于前导光柱后侧的调光膜,与前导光柱相对齐并设置于调光膜后侧的后导光柱,设置在后导光柱后侧入光面处的若干LED光源,以及套设在后导光柱外侧的深色格栅;当LED光源不点亮且调光膜通电时,调光膜在内部材料分子有序排列的作用下呈表面透明状态;当LED光源点亮且调光膜断电时,调光膜在内部材料分子无序排列的作用下呈表面半透明均光特性,所述LED光源发出的光线能够经后导光柱入射再进入调光膜内发生漫反射。本发明采用双层厚壁导光柱间夹贴调光膜的方案,通过调光膜的通断电来实现不点灯时的晶莹剔透效果以及点灯时更大角度的均匀发光效果。
