Abstract
This invention is suitable for optical technology field. A lens, LED back light module and display device are provided. The lens receives light emitted by the light source through a light incident surface, the light emitted by the light source enters in the lens, a part of the light is refracted from one light exiting surface, a part of the light is reflected from one light exiting surface to another light exiting surface or bottom surface, then is reflected from the another light exiting surface or bottom surface to further another light exiting surface and finally is refracted from the further another light exiting surface, therefore the light emitted by the light source is separated in the lens, and then each light is refracted from different light exiting surface of the lens thereby increasing the light exiting area and the uniformity. The lens of the present invention is suitable for the LED back light modules and display devices.
