As mentioned above, in normal times, the power supply e is applied, so the power supply e is step-down rectified by the rectifier circuit 2, smoothed by the smoothing capacitor 8, and charged to the battery via the current-limiting resistor 7 and the diode 46. There is. Note that the Cds 41 and the resistor 45 are set in advance so that when the surroundings are bright, such as when the surroundings are bright, the resistance value of the Cd 541 is small and the transistor 42 is not conductive, but when the surroundings are dark, the transistor 42 is conductive. Therefore, when the surroundings are bright, the transistor 42 is non-conductive, so the transistor 43 is also non-conductive, and no current flows to the emergency lamp 47, so it does not light up. Further, since no voltage is generated at the collector of the transistor 42, no gate voltage is applied to the N-gate thyristor 31.
The N-gate thyristor 31 can generate a trigger pulse voltage, so it does not trigger the triac 1 and the service lamp L, which is the load of the triac 1, does not light up.

Next, when the surroundings become dark and the resistance value of Cds 41 increases, a base current flows to the transistor 42, a collector current flows to the transistor 42, and a base current also flows to the transistor 43, but when the commercial AC power supply e When the voltage is normally applied, the rectifier/current circuit 2
The battery 5 is charged via the. Therefore, since the charging current flows through the diode path 46, the transistor 43 is biased to l and becomes non-conductive. Therefore, in this state, no current flows to the emergency lamp 47 and it does not turn on, but as the collector current of the transistor 42 flows,
A DC voltage is applied to the gate of the N-gate thyremeter 31, and the N-gate thyremeter 31 generates a trigger pulse voltage, which is applied to the gate of the triac 1 through the pulse trannu 36, the triac 1 is turned on, and the load lamp I7 is turned on. Light. If a power outage occurs for some reason in this state, the regular lamp L that was lit by the AC power supply will go out, and the transistor 43 will be reverse biased while charging the battery 5 through the rectifier circuit 2 described above. The current that was flowing disappears, and a base current flows through the transistor 43.
The transistor 43 becomes conductive, and the emergency lamp serving as the load receives energy from the battery 5 and lights up.

As mentioned above, the 3-terminal sirinuta connected in series with the load and the primary winding of the charging transformer are connected in parallel.
It has a circuit and a battery that rectifies and charges the secondary winding output of the mJ charging tranne, and the output of this rectifier circuit generates a trigger signal for the 3-terminal cyrisk during darkness, lights up the load, and when it is dark due to a power outage. This is a security light that has an emergency lamp that is supplied with battery power and turns on at night, and neither the normal lamp L nor the emergency lamp 47 turns on at night (when it is dark), regardless of the presence or absence of commercial AC power. When the commercial power supply is available, the regular lamp L is lit by the power supply, and in the event of a power outage, the emergency lamp 47 is lit by the secondary battery 5 power supply.
