Title: Preventing circuit for erroneous lighting
Inventor: TAKAGI KENICHI
IPC: H04B1/16
Filed: 1981-07-20
Abstract: PURPOSE:To prevent a pilot lamp from turning on erroneously by detecting a DC voltage proportional to the electric field intensity of a received signal and operating a switch by utilizing the detected voltage, and thus controlling the pilot lamp. CONSTITUTION:A DC voltage proportional to the electric field intensity of a received signal is outputted from the output terminal A of an IC3 for RF amplification of FM or AM. A pilot lamp LED3 is connected to the output of an IC4 for FM or AM stereos or traffic information SK, and the pilot lamp LED3 is capable of turning on and off by itself. A transistor switch SW is normally turned off, but when a high DC voltage is outputted from the terminal A of the IC3, the SW turns on to ground the cathode K of the LED3, which is biased forward to turn on. Consequently, only when the voltage is high, the LED3 is turned on securely to prevent its erroneous lighting, confirming that a desired signal is received.
