Described transparent diffuser is hyaloplasmic sphere bubble lampshade or transparent light distributing cap.

The utility model compared with prior art has the following advantages:

1, simple in structure, reasonable in design.This free from glare white light LEDs light fixture by aluminium base, be fixed on blue-ray LED light source on the aluminium base, the lamp heat-radiating device that joins with aluminium base and realize free from glare and white light conversion double-deck lamp casing constitute, simple in structure, reasonable in design.

2, illumination is even, colour rendering good.The double-deck lamp casing internal layer of this free from glare white light LEDs light fixture is a yellow phosphor coating, the skin of double-deck lamp casing is transparent diffuser, the blue-ray LED light source can be converted to white light effectively, and make the some shaped laser spot of LED lamp zoom into scattered light, make the illumination in the effective lighting scope more even, colour rendering is better.

3, cost is low, and result of use is good.The utility model mainly is to be yellow phosphor coating by internal layer, outer realize free from glare and white light conversion for the double-deck lamp casing of transparent diffuser, compare with coating fluorescent material realization white light on led chip, technique process is simple, and cost of manufacture is low, and makes the emergent ray of LED more reasonable, eliminated dazzle, energy-saving and cost-reducing, make light soft not dazzling, result of use is good.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.
