Patent ID: 8233803

Claim:
An infrared light emitting device for controlling at least one infrared receiving device, the infrared light emitting device comprising: a base plane and a longitudinal axis substantially perpendicular to the base plane; a radio frequency receiver to receive and demodulate a radio frequency control signal to provide a demodulated control signal; a processor functionally coupled to the radio frequency receiver to receive the demodulated control signal and to generate a corresponding drive signal; a plurality of infrared light sources functionally coupled to the processor and responsive to the drive signal to generate a plurality of modulated infrared light emissions to control the at least one infrared receiving device, each of the plurality of infrared light sources having an optical axis, a first group of the plurality of infrared light, sources being disposed on the infrared light emitting device such that the optical axis of each of the plurality of infrared light sources in the first group is at a different angle with respect to the longitudinal axis, the modulated infrared light emissions controlling the at least one infrared receiving device; and a power supply to provide operating power to at least one of the radio frequency receiver, the processor, or the plurality of infrared light sources, wherein the total infrared power emitted by the plurality of infrared light sources whose optical axis is at an angle of greater than a predetermined angle with respect to the longitudinal axis is greater than the total infrared power emitted by the plurality of infrared light sources whose optical axis is at an angle of less than the predetermined angle with respect to the longitudinal axis, the total infrared power emitted by the plurality of infrared light sources whose optical axis is at an angle of less than the predetermined angle with respect to the longitudinal axis being greater than zero.
