Abstract

The invention discloses a control method of an LED emergency lamp. The control method is used for a specific LED emergency lamp. The main process of the control method comprises the following operation steps: 0, starting; 1, executing a mains supply input detection process; 2, judging whether the commercial power input returned by the commercial power input detection process is commercial power input stop, if so, executing a step 3, and if not, executing a step 4; and 3, executing a lighting process, and then executing the step 2. The method is low in cost, simple in structure and long in service life, faults can be found in time, the problems of battery bulging and the like can be found in time, and a new thought is created.

Description

Technical field [0001] The invention relates to a lamp, in particular to a control method of an LED emergency lamp. Background technique [0002] The lighting activated due to the power failure of the normal lighting is called emergency lighting. Emergency lighting is different from ordinary lighting. It includes three types: standby lighting, evacuation lighting, and safety lighting. The conversion time is determined according to the actual project and relevant regulations. Emergency lighting is an important safety facility for modern public buildings and industrial buildings. It is closely related to personal safety and building safety. When a fire or other disaster occurs in a building, and the power supply is interrupted, emergency lighting plays an important role in the evacuation of personnel, the fire and rescue work, the continued operation of important production and work, or the necessary operation and disposal. [0003] The prior art LED emergency lights have problems...
