LED explosion-proof lamp is a kind of electrical equipment in special industries. The equipment is mainly used to solve lighting problems. It includes a lamp housing, a luminous body and a battery arranged inside the lamp housing, and a front end of the lamp housing. The lampshade and the switch arranged on the surface of the lamp housing. Its main feature is that: the illuminator is a high-power LED module, and a wide voltage input drive circuit is arranged between the illuminator and the battery; the wide voltage input drive circuit includes a constant current chip, and the constant current chip and the battery form a power supply module. The LED module is connected to the constant current chip, the power module and the LED module are glued together; the lampshade and the lamp housing are ultrasonically welded.
The precautions for the use of LED explosion-proof lamps are as follows:
1. Regularly eliminate dust and dirt on the shell of explosion-proof lamps to improve the light efficiency and heat dissipation performance of lamps. The cleaning method can be sprayed with water (above the mark on the lamp) or wiped with a damp cloth according to the protective ability of the lamp shell. When cleaning with water spray, the power supply should be cut off, and it is strictly forbidden to wipe the plastic shell (transparent part) of the lamp with a dry cloth to prevent the generation of static electricity.
2. 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.
3. If the light source is damaged, turn off the light in time and notify the replacement, so as not to cause the electrical components such as the ballast to be in an abnormal state for a long time due to the failure of the light source to start.
4. If there is accumulated water in the lamp cavity 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 shell.
5. When opening the lampshade, the cover should be opened after power off according to the requirements of the warning sign.
6. After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal becomes hard or sticky, whether the wire insulation layer is green and carbonized, and whether the insulating parts and electrical components have deformation and scorch marks. If these problems are found, they should be repaired and replaced in time.
7. Before closing the cover, use a damp cloth (not too wet) to gently wipe the light and transparent parts of the lamp to improve the light efficiency of the lamp. A thin layer of 204-1 replacement type anti-rust oil should be applied on the flameproof joint surface, and attention should be paid to whether the sealing ring plays a sealing role in the original position when closing the cover.
8. The sealed part of the lamp should not be disassembled and opened frequently. Patented area road sealing technology; more in line with new explosion-proof technology.
