In addition to being used as street lights under normal circumstances, led street lights also have applications in some unique aspects, mainly including normal maintenance and emergency, indoor equipment areas such as pump rooms, and petrochemical equipment areas.

It is mainly for patrol inspections of pipelines and equipment, emergency situations, etc., which require mobile explosion-proof led lamps. In the past, dry battery portable lamps with halogen bulbs were used as the light source. They not only have low explosion-proof performance, short bulb life, high dry battery consumption, but also low brightness and short working time. Led explosion-proof flashlights and led explosion-proof searchlights have become the new favorites of petrochemical workers due to their high brightness, long working hours, and maintenance-free, and have gradually eliminated those traditional emergency lights. The application of indoor equipment such as pump rooms is mainly indoor equipment such as pumps. The lighting area is equipment and instruments. The equipment height of the lamps is usually 4-6 meters, and the illumination requirement is about 30LUX.

The application in the petrochemical plant area is mainly outdoor or indoor equipment such as towers, tanks, pipelines, etc. The local lighting area is instrumentation equipment or pedestrian passages, etc. The equipment height of the lamps is usually 2-4 meters, and the illumination usually needs to be about 20 LUX. Because most areas are zone 1 or even zone 0, the requirements for the explosion-proof performance of the lamps are extremely strict. The basic requirements are explosion-proof or above. Most of them are outdoor areas. The lamps are required to have good waterproof and corrosion resistance. At the same time, most areas are a few meters or even higher. It is extremely difficult to replace and maintain lamps in the high-altitude area of 100 meters, high temperature and high pressure.
