Abstract
A light emitting device, including an LED semiconductor die, a photoluminescent structure and a reflector, is disclosed. The photoluminescent structure with a beveled edge surface is disposed on top of the LED semiconductor die, wherein a lower surface of the photoluminescent structure adheres to an upper surface of the LED semiconductor die. A reflective resin material is disposed surrounding edge surfaces of the LED semiconductor die and the photoluminescent structure forming a beveled reflector. A method to manufacture the above light emitting device is also disclosed. Advantages of this light emitting device with beveled reflector include increasing the light extraction efficiency, making the viewing angle tunable, improving spatial color uniformity and reducing the light source etendue realized in a compact form-factor size.
