LED explosion-proof light is a kind of electrical equipment used in a special industry. It mainly solves the problem of lighting. Its main structure includes the lamp shell, the lampshade set in front of the lamp shell, the illuminating body and the battery set inside the lamp shell and the switch set on the outer surface of the lamp shell. Its general characteristics are: the emitter is a high-power LED module, a wide voltage input drive circuit is arranged between the emitter and the battery; The wide voltage input drive circuit includes a constant current chip, the constant current chip and the battery form a power module, the LED module is connected to the constant current chip, the power module and the LED module are glued together; Ultrasonic welding is used between the lampshade and the lamp shell.
Maintenance method of LED explosion-proof light:
1. When the fixture is found to be repaired in time, it must also be repaired in a safe environment;
2. In order to prolong the service life, do not install the LED explosion-proof light in a humid environment, because the humid environment has a great destructive effect on the lamp;
3. Regularly clean the LED explosion-proof light to eliminate the dust and dirt on the shell of the explosion-proof lamp. The way of cleaning can be according to the protection ability of the lamp shell, choose to spray water or wipe with a wet cloth. The use of water cleaning, should be cut off the power supply, do not use dry cloth to scrub the plastic shell of lamps and lanterns, to avoid static electricity;
4. Maintenance and repair personnel need to be trained on the job, understand the application function of lamps and lanterns, and know the application requirements. Repair personnel must have professional knowledge, understand the product structure of lamps;
5. When the light source is damaged, the light should be turned off in time and replaced to avoid the abnormal condition of the ballast and other electrical components for a long time due to the failure of the light source to start;
6. Check the plastic shell of the lamp (clear) whether there is serious discoloration, such as severe discoloration, clarify the plastic has been aging. Check whether the clear parts have been impacted by foreign bodies, whether the protective net is loose, welding, corrosion, etc. If any, it should be stopped and repaired and replaced in time.
7. If there is water in the lamp chamber of the LED explosion-proof light running in a humid environment, it should be removed in time, and the sealing parts should be replaced to ensure the protective function of the shell.
8. When a fault occurs, the power must be cut off immediately, and the operation cannot continue to prevent the occurrence of safety accidents.
