Brightness improving structure of light-emitting module with an optical film surface layer
Abstract:
A brightness improving structure of a light-emitting module with an optical film surface layer 12, wherein a light-emitting part 20 is provided inside a transparent envelop 10 and may emit ultraviolet or blue light, the said transparent envelop 10 has first wall and second wall, first inside wall 101 and second inside wall 103 are oppositely formed inside thereof, first outside wall 102 and second outside wall 104 are oppositely formed outside thereof. The first wall is partly or entirely provided with the optical film coating 12, the optical film coating 12 may at least reflect the ultraviolet or blue light exciting fluorescent/phosphorescent light, and may pass light rays comprising visible light. A visible light layer or both the visible light layer and a reflective layer are provided on the second wall, and the said light-emitting part 20 is placed at a setting location from the envelop 10.
