Problems solved by technology

However, the common emergency lighting can only be used when the user turns on the power switch of the emergency lighting when the lighting fails.
However, the failure of the lighting usually occurs instantaneously. At this time, if the location of the emergency lighting is relatively hidden, it cannot be illuminated in time, which will have a certain impact on life, and there will be safety hazards

Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0011] An emergency lighting device, its electrical connection diagram is as follows figure 1 shown. It includes a power supply, a rectifier bridge, a normal lighting branch and a backup lighting branch. After the AC power is rectified by the rectification bridge, it outputs a DC voltage to supply power for the normal lighting branch and the backup lighting branch. The normal lighting branch includes a current-limiting resistor R1 and a general lighting lamp L1, which are connected in series and connected in parallel at the output end of the rectifier bridge.

[0012] The backup lighting branch includes a backup lighting lamp L2, a thyristor KP, a triode T1, a second resistor R2, a third resistor R3 and a fourth resistor R4. Wherein the branch connected in series by the thyristor KP and the standby lighting lamp L2 is arranged in parall...

Abstract

The invention discloses an emergency lighting device, which comprises a power supply, a rectifier bridge, a normal lighting branch and a standby lighting branch. An alternate current power supply outputs direct current voltage after rectifying by the rectifier bridge and supplies power for the normal lighting branch and the standby lighting branch; the standby lighting branch comprises a standby lighting lamp, a silicon-controlled rectifier, a triode, a second resistor, a third resistor and a fourth resistor; and a control circuit of the standby lighting branch consists of the triode, the fourth resistor and the silicon-controlled rectifier. Through a controllable triggering principle of the triode and the silicon-controlled rectifier, a standby emergency lamp is lightened; and emergency lighting is provided for a user, so that an instant automatic switching function of the emergency lighting lamp is realized, the requirements of the user are met, and the life and work are not affected.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to an emergency lighting device. Background technique [0002] With the gradual improvement of people's requirements for working and living environments, more and more people pay attention to intelligent buildings. A series of intelligent designs make buildings safe, convenient, efficient and energy-saving. The lighting system is an indispensable part of an intelligent building. When the lighting fails, the emergency lighting is usually used to replace the original lighting to provide lighting for the corridors and stairwells. Of course, the same is true for indoor lighting. When the normal lighting fails, because the flashlight can only be used as temporary lighting, its light is dim, and long-term use is not good for eyesight. Candles are gradually eliminated because they are not environmentally friendly. Therefore, indoor emergency lighting It is also usually done with emergen...
