When replacing the bulb (tube) of the explosion-proof LED lamp, the explosion-proof joint surface of the explosion-proof lamp should be properly protected and not damaged; the explosion-proof surface after cleaning should be coated with phosphating paste or 204-1 anti-rust oil to prevent other paints from being painted. ; There shall be no rust layer on the explosion-proof surface. If there is slight rust, there should be no pockmark after cleaning. It is very important for the increased safety lamps to ensure that the sealing ring used for dustproof and waterproof must be intact. Assuming that the sealing ring is seriously damaged, replace it with a sealing ring of the same standard and material, and replace the entire luminaire if necessary. When overhauling, pay attention to whether the lampshade is intact. If it is split, replace it immediately.
Protection and repair personnel need to undergo on-the-job training to understand the performance of lamps and lanterns, and clarify the application requirements. Repair personnel must have professional knowledge and understand the product structure of lamps.

Check whether the transparent parts have been impacted by foreign objects, and whether the protective net is loose, desoldered, corroded, etc. If so, stop using it and repair and replace it in time.
1. Light transmittance: The light transmittance of PC board is comparable to that of glass. The UV-coated board will not turn yellow, fog, and poor light transmission when exposed to sunlight.
2. Impact resistance: The impact strength of the PC board is 250-300 times that of ordinary glass, 30 times that of acrylic plates of the same thickness, and 2-20 times that of tempered glass. There is no crack when dropped from two meters below a 3kg hammer. Broken Glass" and "Sound Steel".
3. Light weight: the specific gravity is only half of that of glass, saving the cost of transportation, handling, installation and supporting the frame.
4. Flame retardant: confirmed by the national standard GB50222-95. The ignition point of the PC board itself is 580 degrees Celsius, and it will self-extinguish after leaving the fire. No toxic gas will be generated when burning, and it will not contribute to the extension of the fire.
