フィードバック及びワイヤレス制御を有する統合型のランプ
Document Type and Number:
Japanese Patent JP4685016
Kind Code:
B2
Abstract:
A lamp assembly (50) employs a heat sink (54) defining a circuit housing area (55). A LED assembly (51) is disposed within the lamp assembly (50) and the heat sink (54) dissipates heat away from LED assembly (51). One or more LEDs of LED assembly (51) emit a light in response to a flow of a LED current through the LEDs. The lamp assembly (50) may further include a reflector (52) defining a light reflecting area (53). One or more optical power sensors of LED assembly (51) sense an emission of the light by LED(s). A LED driver circuit (30) is disposed within the circuit housing area (55) to control the flow of the LED current through the LED(s) as a function of a sensing of the emission of the light by the optical power sensor(s) and a desired level of one or more lighting variables associated with the LED(s).
