Embodiment Construction

[0011] figure 1 It is the circuit schematic diagram of the present invention, the power supply of the illuminating lamp L is provided by the primary stage of the switch QF, R1, D, C provide the trigger current for the thyristor VT, DZ can limit the voltage of the trigger terminal of the thyristor VT, and has a certain effect on the thyristor VT Protective function, the LED D is also used as a power indicator light. When the switch is turned on normally, the secondary of the switch supplies power to the LED in the optocoupler IC through the current limiting resistor R2 to make it glow, and the triode inside the optocoupler is turned on. Through the switch K, the trigger current of the thyristor is discharged, the thyristor is cut off, and the lighting lamp does not emit light. When the secondary of the switch loses the electrical signal due to tripping, the light-emitting diode in the optocoupler does not emit light due to power loss, and the internal triode At the end, the thy...

Abstract

This invention relates to an automatic tripping lamp, which comprises a supply circuit, a control circuit and a signal circuit, wherein the control circuit comprises a silicon controlled rectifier (SCR) and some other elements, and the signal circuit comprises a current-limiting resistance and a photocoupler. The power of the lamp is supplied by a primary electric brake, and is controlled by the SCR; the electric signal sent from a secondary electric brake is transmitted to the SCR after being isolated by the photocoupler, and disconnects the SCR, then the lamp is off; when the secondary electric brake is losing electric signal caused by tripping, the SCR breaks over and the lamp lights up automatically, then users can switch on the electric brake conveniently, and after the electric brake is switched on, the SCR disconnects the control of electric signal and the lamp lights off automatically.

Description

Technical field: [0001] The invention relates to an automatic lighting lamp for tripping, which is an intelligent control electric appliance for safe use of electricity, which is suitable for being installed next to an electric switch, and can automatically illuminate when the electric switch trips, bringing safety and convenience to the operation of the electric switch. Background technique: [0002] In people's life, often encounter the situation of tripping suddenly due to various reasons at night. At this time, lighting is urgently needed, and people generally look for flashlights in the dark, which is very inconvenient. Invention content: [0003] In order to solve the lighting problem after tripping, the invention provides a tripping automatic lighting lamp, which is installed next to the switch and can automatically illuminate when the switch is tripped, bringing safety and convenience to the operation of the switch. [0004] The technical solution adopted by the pr...
