  • Patent number: 9634208
    Abstract: An LED die (26) conformally coated with phosphor (28) is mounted at the base (24) of a shallow, square reflector cup (16). The cup has flat reflective walls (20) that slope upward from its base to its rim at a shallow angle of approximately 33 degrees. A clear encapsulant (30) completely fills the cup to form a smooth flat top surface. Any emissions from the LED die or phosphor at a low angle (48, 50) are totally internally reflected at the flat air-encapsulant interface toward the cup walls. This combined LED/phosphor light is then reflected upward by the walls (20) and out of the package. Since a large percentage of the light emitted by the LED and phosphor is mixed by the TIR and the walls prior to exiting the package, the color and brightness of the reflected light is fairly uniform across the beam. The encapsulant is intentionally designed to enhance TIR to help mix the light.

  • Patent number: 9080743
    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.
