Embodiment 1

[0024] The invention provides a time-delay lighting switch, such as figure 1 As shown, it includes a normal lighting switch circuit 1, a voltage divider circuit 2, a power storage unit 3, an auxiliary lamp driving circuit 4 and an auxiliary lamp L2, wherein the normal lighting switch circuit is used to control the normal lighting or extinguishing of the lighting lamp L1 , consisting of a lighting switch K, a fuse G, and a lighting lamp L1 connected in series at both ends of the AC power supply in sequence; During lighting, that is, when the switch K is turned on, part of the voltage is taken and charged to the power storage unit 3. One end of the auxiliary lamp drive circuit 4 is connected to the output end of the power storage unit 3, and the other end is connected to the auxiliary lamp L2 for controlling the power storage unit. The electric unit 3 supplies power to the auxiliary lamp after the illuminating lamp is extinguished to delay lighting or extinguishing.

Embodiment 2

[0030] Such as Figure 4 As shown, the present embodiment is basically the same as Embodiment 1, and its difference only lies in:

[0031] The power storage unit 3 is composed of a diode D1, a battery charging circuit 31, a rechargeable battery E and a filter capacitor C2. Among them, the diode D1 is used to control the unidirectional flow of current, the battery charging circuit 31 is used to control the voltage divider circuit 2 to charge the rechargeable battery E, and the filter capacitor C2 is used to stabilize the voltage across the rechargeable battery E and prevent its fluctuation. In practical applications, when the voltage across the rechargeable battery E is not strictly required, the filter capacitor C2 can also be omitted as needed.

[0032] The voltage divider circuit 2 is formed by a zener diode D4 connected in parallel with a reversely connected diode D2, wherein the zener diode D4 is used to stabilize the voltage at the input end of the power storage unit 3, ...

Embodiment 3

[0036] Such as Figure 7As shown, the difference between this embodiment and Embodiment 2 is only that: the voltage divider circuit 2 includes a diode D2, a Zener diode D5, current limiting resistors R1, R2 and a transistor Q. Among them, the transistor Q is used to stabilize the voltage at the input terminal of the power storage unit 3, the voltage regulator diode D5 is used to provide the reference voltage for the transistor Q, the diode D2 is used to bypass the reverse current in the voltage dividing circuit 2, the current limiting resistor R1, R2 and transistor Q make the current that can pass in the normal lighting circuit larger, which is suitable for the lighting lamp L1 of higher power.

Abstract

The present invention provides a delay illumination switch. The delay illumination switch comprises a normal illumination switch circuit, a voltage division circuit, an electricity-storage unit, an auxiliary light driving circuit and an auxiliary light. The normal illumination switch circuit is configured to control an illuminating lamp to normally light up or go out; the voltage division circuit is connected in series with the normal illumination switch circuit, is connected with the input end of the electricity-storage unit and takes part of voltage when normal illumination and performs charging of the electricity-storage unit; and one end of the auxiliary light driving circuit is connected with the output end of a charging circuit, and the other end of the auxiliary light driving circuit is connected with the auxiliary light to drive the electricity-storage unit to supply power to the auxiliary light after the illuminating lamp goes out to allow the auxiliary light to light up for a while. The delay illumination switch can start using the electric quantity stored in the electricity-storage unit to supply power to the auxiliary light to allow the auxiliary light to light up when the illuminating lamp goes out, and can reach the safer effect than a transmission delay switch according to the brightness of the auxiliary light required being controlled and the lighting time.

Description

technical field [0001] The invention relates to a time-delay lighting switch. Background technique [0002] After the traditional light switch is disconnected, the light goes out immediately, therefore, it will cause inconvenience for the user to move in the dark for a short time at night. To solve this problem, time-delay lighting fixtures have been widely used, but the lighting fixtures in the prior art generally operate on the principle that after the main switch is disconnected, another circuit continues to supply power to the lighting lamp for a period of time, so that the lighting lamp can Continue to light up for a while after turning off the switch. Although this design solves the problem of being in the dark after turning off the light, due to the existence of the delay circuit, when the user disconnects the switch to change the lamp or repair the circuit of the lamp holder, although it is safe for the lamp holder to be powered off subjectively, But in fact the la...
