1, LED lamps should pay attention to regularly clean the dust and dirt on the lamp shell, keep the shell clean, can improve the lighting effect and heat dissipation performance of the lamp, cleaning method according to the lamp shell protection ability and change. For example, the protection level of lamps and lanterns is IP65, then we know that 6 is the dust-proof level, meaning that dust is completely prevented from entering; 5 indicates the waterproof level, which means that there is no harm in rinsing with water. Therefore, when we clean with water jet, we should cut off the power supply. It is strictly prohibited to scrub the plastic shell of the lamp with dry cloth (transparent) to prevent static electricity.

2. Check whether the transparent parts have been impacted by foreign bodies, and whether the protective net is loose, welding off, corrosion, etc. If so, stop using, timely maintenance and replacement.

3. If there is water in the lamp chamber used in humid environment, it should be removed in time and replaced with sealing parts to ensure the protective performance of the shell. After the lamp leaves the factory, in the process of final installation of the lamp, the lamp may also produce water phenomenon because of improper installation, resulting in the lamp seepage can not be used normally. Therefore, the installation method should also be appropriate to ensure the life of the lamp.

4. In the maintenance of lamps, the following points should be checked after opening the cover: 1. Whether the flameproof joint surface is in good condition 2. Whether the rubber seal becomes hard or sticky 3. Whether the insulation layer of the wire is green and carbonized 4. Whether the insulation parts and electrical components have deformation and coke marks. If the above problems occur, they should be repaired and replaced in time.

5, LED explosion-proof lamp before installation, to check from the nameplate and product manual: explosion-proof type, category, level, group; The protection level of the enclosure; Installation method and fastener requirements for installation, etc. The installation of the explosion-proof lamp shall ensure that it is fixed firmly, the fastening bolt shall not be replaced arbitrarily, and the spring washer shall be complete.

6, dustproof, waterproof sealing ring installation should be placed as is; At the cable inlet, the cable should be closely matched with the sealing gasket. The section of the cable should be circular, and there should be no concave and convex defects on the surface of the sheath. The excess inlet shall be sealed according to the explosion-proof type, and the compression nut shall be tightened to seal the inlet.

7. Check whether the transparent parts have been impacted by foreign bodies, and whether the protective net is loose, unwelded, corroded, etc. If so, stop using, timely maintenance and replacement.

8, open the lampshade, should be according to the warning sign requirements, off the power after the cover.
