Abstract
A Method and System for Preventing Bum-out of Infrared Transmitter Diodes is disclosed. The preferred method and system detects when the Ir transmitter(s) are approaching or have achieved an overtemperature condition. Once an overtemperature condition is detected, the preferred system will interrupt electrical transmit power to the transmitter until such time as the overtemperature condition is dissipated. Furthermore, the system and method will send a standby signal to the Central Processing Unit or communications controller when an overtemperature condition is detected. Finally, it is yet another feature that the system emit status signals perceptible to the human senses when normal and abnormal temperature conditions are detected in the transmitter.
