(54)	Casing structure with yellow light passing surface and its manufacture method

(57) A casing structure with yellow light passing surface includes a transparent casing (10) and a yellow preparation (11) uniformly sprayed on a surface of the transparent casing (10), thereby to absorb the light under 500 nm wavelength, so that it can completely cut off the ultraviolet radiation, and also can provide some additional effects, such as environmental protection, the power saving and the mosquito repelling. The invention also provides a manufacture method of a casing structure with a yellow light passing surface.
