る。 Next, the operation of the electric circuit will be explained. When the circuit is connected to a commercial power supply, only one half-wave of the secondary voltage taken out from the secondary side of the transformer 16 is taken out by the rectifying diode 41, smoothed by the smoothing capacitor 46, and sent to the secondary battery 42.
to charge. When the next power outage occurs, the secondary battery 42
A base current flows from the positive electrode of the control transistor 44 through the bias resistor 47 to the base of the control transistor 44, and from the emitter of the transistor 44 to the negative electrode of the secondary battery 42, turning on the control transistor 44. Therefore, the light bulb 24 is lit using the secondary battery 42 as a power source. However, when the surroundings where the ceiling fan 1 is used are bright, that is, the illuminance is high, the resistance value of the photoconductive element 27 is small and the light control transistor 48 is turned off, and as a result, the base current flows through the control transistor 44. It doesn't flow and turns off. Therefore, if the surroundings are bright, even if there is a power outage, the control transistor 44 will not turn on, the power outage light will not turn on, and the secondary battery 42 will be wasted.
can prevent the consumption of Next, when the surroundings become dark and the resistance value of the photoconductive element 27 increases, the resistor 4
Base current flows from the secondary battery 42 through 9 to turn on the light control transistor 48, and its collector current flows to the base and emitter of the control transistor 44, turning on the transistor 44.

いものである。 Therefore, when there is a power outage and the light bulb 24 of the power outage light turns on, the photoconductive element 27 that senses the surrounding brightness is installed in the same atmosphere as the light bulb 24, so that it senses the light and turns the light bulb 24 on. Lights out. However, when the light is turned off, the surroundings become dark and the light bulb 24 is turned on, and the above-mentioned turning off and lighting operations are repeated during a power outage. 2
Since the light bulb 24 is housed in the lower part of the interior of the light bulb 5 to block the light from the light bulb 24, stable lighting can be performed during a power outage without being affected by the light bulb 24. Furthermore, the photoconductive element 27 is placed close to the transparent cover 31 so that it reacts only to ambient light. Furthermore, the support rod 25 for attaching the transparent cover 31 is used as a storage part for the photoconductive element 27 and also as a light shielding body that blocks the light from the light bulb 24, and requires special structure and parts. This is not the case.
