Title:
INTEGRATED LAMP WITH FEEDBACK AND WIRELESS CONTROL
Document Type and Number:
WIPO Patent Application WO2005024898
Kind Code:
A3
Abstract:
A lamp assembly (50) employs a reflector (52) defining a light reflecting area (53), and a heat sink (54) defining a circuit housing area (55). A LED assembly (51) is disposed within the light reflecting area (53) and 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. 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 witth the LED(s).
