LED explosion-proof lights must be regularly maintained
Although manufacturers give LED explosion-proof lamps five-year warranty, but in the use of the process, we must always check the use of LED explosion-proof lights, not to the problem, and then to solve, often to clean up the dust on the heat sink fins, a long time More dust covers the LED's explosion-proof lamp's heat-dissipation performance, which in turn increases the light attenuation and service life of the lamp.
1 Maintenance personnel need to be trained on the job to understand the performance of the lamps and use requirements clearly. Maintenance personnel must have professional knowledge and be familiar with the structure of the lighting products.
2 Regularly eliminate dust and dirt on the explosion-proof lamp housing to improve the light efficiency and heat dissipation of the lamp. The cleaning method can be based on the protection capability of the lamp housing, using water spray (over the shade on the lamp) or using a damp cloth. When cleaning with water spray, the power should be cut off. Never use a dry cloth to scrub the plastic housing (transparent parts) of the lamp to prevent static electricity.
3 Check whether the plastic casing (transparent parts) of the lamp has serious discoloration, such as severe discoloration, indicating that the plastic has deteriorated. Check whether the transparent parts have been affected by foreign material, whether the protection network has loosened, soldered, and corroded. If so, use should be stopped and repaired and replaced in time.
4 The light source should be turned off in a timely manner to notify the replacement of the light source so as to prevent the ballast and other electrical components from being in an abnormal state for a long time because the light source cannot be started.
5 If there is accumulated water in the cavity of the lamp used in the humid environment, it should be promptly removed. Replace the sealing parts to ensure the protective performance of the housing.
6 When you open the lamp cover, you should press the warning label to open the cover after the power is turned off.
7 After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal is hardened or sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components are deformed and burned. If these problems are found, they should be promptly repaired and replaced.
8 Maintenance The replacement lamp, parts and electrical components should be of the same type, size, size, and performance as the light source, components, and electrical components prior to service replacement.
9 Apply a damp cloth (not too wet) before closing the cover to light the light return and transparent parts of the lamp to improve the efficacy of the lamp. A layer of 204-1 displacement rust preventive oil should be applied thinly on the flameproof joint surface. When the lid is closed, attention should be paid to whether the sealing ring plays a sealing role in the original position.
10 The sealed part of the lamp should not be frequently disassembled and opened.
