LED LED LED LED LENS AND LED LIGHT SOURCE COMPRISING LED LENS

摘要

LED light source including LED lens and LED lens. The LED lens comprises a central curved surface 1 and a bottom surface 2 located in the plane of incidence and a side surface 3, a first upper curved surface 4 and a second upper curved surface 5 all located on the exposed surface, (6) located on the first upper curved surface (4) and on the second upper curved surface (5). The position of the dispersed micro-structure 6 corresponds to the position of the bright ring in the LED light intensity distribution. Since the dispersed micro-structure 6 disperses light emitted to the outside of the first upper curved surface 4 and the second upper curved surface 5 to form a bright ring, light at a position where the bright ring is formed is emitted The light intensity at the position where the bright ring is formed can be reduced and the light intensity at the position where the dark ring of the LED light source is located can be improved And the uniformity of the light intensity distribution of the LED light source can be improved.
