What are the maintenance precautions for hazardous area light fittings?

- Regularly eliminate dust and dirt on the hazardous area light fittings housing to improve the light efficiency and heat dissipation performance of the lamp. The cleaning method can be sprayed according to the protective ability of the lamp housing (above the sign on the lamp) or with a damp cloth. When cleaning with water spray, the industrial light fittingspower should be cut off. It is strictly forbidden to wipe the plastic housing (transparent part) of the industrial light fittings with a dry cloth to prevent static electricity.
- Check whether the industrial light fittingstransparent part has been damaged by foreign matter, and whether the protection net is loose, desoldered or corroded. If it is, stop using it and repair and replaceindustrial light fittings in time.
- If the hazardous area light fittings source is damaged, the lamp should be turned off in time to inform the replacement, so as to prevent the electrical components such as the ballast from being abnormal for a long time because the light source cannot be started.
- If there is accumulated water in the explosion proof light fittingscavity of the lamp used in the humid environment, it should be removed in time, and the sealing parts should be replaced to ensure the protective performance of the casing.
- When opening thehazardous area light fittings cover, follow the warning card requirements, and open the cover after the power is turned off.
- After opening the hazardous area light fittingscover, check whether the flameproof joint surface is intact, whether the rubber seal is hard or sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components have deformation and scorch marks. If these problems are found, they should be repaired and replaced in time.
- Apply a damp cloth (not excessively wet) before closing the cover to lightly return theexplosion proof light fittingst and transparent parts to improve the light efficiency of the lamp. A layer of 204–1 replacement rust preventive oil should be applied thinly on the flameproof joint surface. When closing the explosion proof light fittingscover, it should be noted that the seal ring is sealed at the original position.
- The sealed part of the explosion proof light fittings should not be removed and opened frequently. Patent area road sealing technology; more in line with national explosion-proof new technology.
- Do not switch the intrinsically safe led lightstoo frequently during use. Although the rated number of switches of the intrinsically safe led lights is 18 times that of the fluorescent lamp, the switch that is too frequent can still have certain adverse effects on the internal electronic components. When maintaining and cleaning intrinsically safe led lights, be careful not to modify or replace the structure and components of the lamps.
