Abstract

The invention discloses a mains supply detection method for a specific LED emergency lamp. The mains supply detection method is used for the specific LED emergency lamp, and comprises: 3.0, starting alighting process, and executing a step 3.1; 3.1, turning off a first switch, a second switch, a third switch and a discharge switch, and executing a step 3.2; 3.2, opening conducting channels of LEDswitches in all LED modules, and executing a step 3.3; 3.3, obtaining the current flowing through the LED of each LED module through an LED current sampling module in each LED module, and executing astep 3.4; 3.4, setting the conducting channel of the LED switch in the LED module of which the value of the current flowing through the LED is not within a preset range to be completely closed, and executing a step 3.5; 3.5, setting the conducting channel of a PMOS in the LED module of which the current value of the LED flowing through is within a preset range to be completely opened, and executing a step 3.6; and 3.6, finishing the lighting process (the normal lamp is in the on state). 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 method for controlling an LED module and an emergency lamp. Background technique [0002] The lighting activated due to the failure of the power supply for normal lighting is called emergency lighting. Emergency lighting is different from general lighting, it includes: standby lighting, evacuation lighting, safety lighting three. The conversion time is determined according to the actual project and relevant specifications. Emergency lighting is an important safety facility in 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, continuous operation of work, or necessary operation and disposal. [0003] The LED emergency lights in the prior art ...
