Description

technical field [0001] The invention relates to lamps, in particular to a supercapacitor testing method for specific LED emergency lamps. Background technique [0002] Lighting that is activated due to the failure of the power supply for normal lighting is called emergency lighting. Emergency lighting is different from ordinary lighting. It includes three types: backup 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, and 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 personnel evacuation, fire rescue work, important production, continued operation of work or necessary operation and disposal. [0003] The LED emergency lights of t...
