Abstract
An auto shutoff mechanism that automatically turns off power to a compact fluorescent lamp (CFL) in the presence of an improper use, or an excessive temperature condition, is disclosed. The auto shutoff includes a temperature transducer, a temperature monitoring circuit, or a microprocessor with memory, and a supporting control circuit. The temperature monitoring circuit, or a predetermined algorithm stored in memory, monitors the ambient temperature for an excessive temperature condition. Upon detection of an excessive temperature condition, the temperature monitoring circuit instructs the control circuit to turn off power to the CFL. Once the detected temperature falls below a predetermined level, power is restored to the CFL.
