Abstract
A LED device includes a LED having a light-emitting surface and adapted for emitting light through the light-emitting surface, and a reflector formed of three or more than three reflecting layers having the peripheral surfaces thereof sloping at different angles and arranged in a stack on the light-emitting surface of the LED for letting the light emitted by the LED pass and/or reflecting and/or refracting the light to enhance luminous uniformity and luminous brightness and to avoid light concentration at the center or the formation of a corona.
Claims11
A high-brightness LED device, comprising:
