Movable emergency lamp

Abstract

A movable emergency lamp comprises a front shell and a rear shell which are matched with each other. The front shell is matched with a transparent cover, a light source, a power source electrically connected with the light source, and a control circuit board are arranged in a cavity where the front shell is matched with the rear shell, a light-sensitive switch circuit is arranged on the control circuit board, the light source is electrically connected with the power source through the light-sensitive switch circuit, and a light sensor electrically connected with the control circuit board is arranged outside the front shell or the rear shell. When the control circuit board detects that a main lighting circuit supplies power, the light sensor does not work; when the control circuit board detects that the main lighting circuit does not supply power, the light sensor starts to work, and when the light sensor senses light, the control circuit board disconnects the light-sensitive switch circuit, and the light source is extinguished; when the light sensor does not sense light, the control circuit board connects the light-sensitive switch circuit, and the light source lights. Whether the emergency lamp is started for lighting or not is determined by detecting whether the light exists or not through the light sensor, so that electric energy is saved.

Description

technical field [0001] The invention belongs to the field of lamps, in particular to a mobile emergency lamp. Background technique [0002] At present, the working principle of the existing emergency lamps is as follows: when the main lighting circuit is unexpectedly powered off, the control module immediately activates the emergency circuit after detection, and the emergency circuit supplies power to the lamps. This kind of emergency lighting will have the following problems: during the day, the lighting is not needed for lighting, and the lighting is turned off. However, if the main lighting circuit is unexpectedly powered off, the control module will also start the emergency circuit after detection, and the emergency circuit will supply power to the lighting. , so that the lamps and lanterns are illuminated, and lighting is not needed during the day, thus causing a waste of electric energy. [0003] In addition, the existing emergency lighting fixtures are generally fixe...

Problems solved by technology

This kind of emergency lighting will have the following problems: during the day, the lighting is not needed for lighting, and the lighting is turned off. However, if the main lighting circuit is unexpectedly powered off, the control module will also start the emergency circuit after detection, and the emergency circuit will supply power to the lighting. , so that the lamps are illuminated, and the lighting is not needed during the day, thus causing a waste of electric energy

[0003] In addition, the existing emergency lamps are generally fixed in a certain area and cannot or are not convenient to move
