In addition to the streetlights used in general conditions, led streetlights are also used in some unique aspects, including the general maintenance and emergency, pump room and other indoor equipment areas and petrochemical equipment areas, the application of led street lights in these areas.
Mainly pipelines, equipment inspection, emergency response, etc. need to move class explosion-proof LED lamps. Previously used dry battery portable lamps with halogen bulbs as light sources, they not only have low explosion-proof performance, short lamp life, large dry battery consumption, low brightness, and short working time. Led explosion-proof flashlights and led explosion-proof searchlights have become the new favorite of petrochemical workers with their high brightness, long working hours and maintenance-free, and gradually eliminated those traditional emergency lights. In the pump room and other indoor equipment applications, mainly for indoor equipment such as pumps, lighting areas for equipment and instruments, etc., the equipment height of the lamps is usually 4-6 meters, the illumination demand is about 30 LUX.
The application in the petrochemical plant area is mainly outdoor or indoor equipment such as towers, tanks, pipelines, etc. The local lighting area is instrument equipment or pedestrian passage, etc. The equipment height of the lamps is usually 2-4 meters, and the illumination usually requires about 20 LUX. Because most areas are Zone 1 or Zone 0, the requirements for explosion-proof performance of lamps are extremely strict. The basic requirements are above the explosion-proof grade, mostly for outdoor areas. The required lamps have good waterproof and corrosion resistance, and most areas are several meters or even High-altitude areas of 100 meters, high temperature and high pressure, and the replacement and maintenance of lamps are extremely difficult.
