摘要:
A light-emitting device capable of generating omnidirectional light utilizing a reflector is disclosed. The light-emitting device, in one aspect, includes a light emitting diode (“LED”) package, a light reflector, and a shell. The LED package, which is mounted on a plate, generates a forward light cone by converting electrical energy to optical energy. The light reflector can be formed with various different shapes that can be placed adjacent to the LED package. A function of the light reflector is to redistribute at least a portion of the forward light cone whereby the overall light illuminated by the light-emitting device complies with LM79 specifications. The shell is used to enclose the LED package and the light reflector and configured to illuminate light in omnidirectional radiation in response to the forward light cone.
