Description

Technical Field

[0001] The utility model relates to the technical field of alarm lamps, in particular to a lighting induction alarm lamp for fire protection engineering. Background Art

[0002] Most of the existing lighting induction alarm lights first install a base, and then install the lighting induction alarm light on the base. The back of the lighting induction alarm light is connected to an external power supply, and the lighting induction alarm light and the base are usually threaded. This way of installing the lighting induction alarm light will cause the lighting induction alarm light to be mixed up during installation. During the later maintenance process, the lighting induction alarm light needs to be rotated, thereby driving the wiring to rotate, which makes the wiring twisted and easy to bend and damage, making replacement inconvenient. In order to avoid twisting and damage of the wiring, each disassembly requires a line connection, which is not only inconvenient to operate but also unsafe. In addition, the size of the lighting area cannot be adjusted, and the use is not flexible enough. Utility Model Content
