BULB TYPE DETECTOR FOR DIMMER CIRCUIT AND INVENTIVE RESISTANCE AND SHORT CIRCUIT DETECTION |
摘要 |
A bulb detection circuit is associated with a dimmer circuit for a lighting system. The bulb detection circuit is operable to detect whether an incandescent or a fluorescent bulb is received in an electric light socket. The socket may be hardwired to the circuit, or could be plugged into an electrical outlet. The bulb detection circuit may utilize a separately inventive method of measuring the resistance by looking at an RC circuit time constant. Further, the bulb detection circuit may utilize a separately inventive method of identifying a short circuit by again looking at the RC circuit time constant.
