Plastic Manufacturing
27/12/2022Workshop lighting is composed of general lighting, regional lighting, local lighting and special task lighting. The quality of workshop lighting has an important impact on production efficiency and production safety. Workshop lighting makes it easy for people to identify objects and reduces visual fatigue.
The lighting in the workshop is not good, which reduces the visual function, causes discomfort, blurs the eyes of the staff, makes it difficult to recognize the relative position of the object, causes work errors, and causes safety accidents.

The installation height of explosion-proof lights in the factory workshop is different according to the actual production situation, so the design height is also different. The distance between the base of the general explosion-proof lamp and the ground is not less than the following values (except when the safety voltage is used): outdoor: 2.5m (installed on the outdoor wall); factory building: 2.5m; indoor: 2m.
The actual installation height of explosion-proof lights depends on the height of the factory building but is not equal to the height of the factory building. For example, if the actual design height of a factory building is 8 meters, then the height between the top of the factory building and the installation lamps must be calculated, such as the distance between the top of the factory building and the installation lamps. If the height of the lamp is 2 meters, then the installation height of the lamp is 6 meters, so when purchasing explosion-proof lamps, it must be noted that the installation height of the lamp is not necessarily the design height of the factory building.
Explosion-proof lamp power used at the installation height of factory workshop explosion-proof lamps:
1. 40W~50W explosion-proof lights are used in the factory workshop of 3 meters to 5 meters
2. 50W~100W explosion-proof lamps are used in the factory workshop of 5m~7m
3. -100W~150W explosion-proof lights are used in the factory workshop of 7 meters to 9 meters
Four, 9 meters ~ 15 meters factory workshop adopts 150W ~ 200W explosion-proof lights
