In the production and operation of any factory or enterprise, lighting is an essential link, as it is crucial to employees’ work efficiency and production safety. However, because the connection between factory lighting and enterprise production safety is implicit, it is often easily overlooked by managers.
Take ordinary fluorescent lamps as an example. They consist of tubes, starters, ballasts, lamp holders, etc. The cause of fire in fluorescent lamps is that the ballast, composed of an iron core and coils, consumes electricity and generates a certain amount of heat. If the ballast is poorly manufactured, has poor heat dissipation, is mismatched with the tube, or works for too long, its internal temperature will rise, damaging the insulation layer of the coils and causing inter-turn short circuits. This produces high temperatures, which can ignite the dust accumulated on the ballast and surrounding combustibles.
Currently, LED explosion-proof lighting is the most widely used in factory lighting. LED explosion-proof lighting can be used in hazardous locations with flammable gases and dust, as it can prevent arcs, sparks, and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment. Its protection level is generally IP65 or higher, with good waterproof, dustproof, and explosion-proof performance. Therefore, in some flammable and explosive production sites, LED-based explosion-proof lighting fixtures are more suitable.
In addition, the following points should be noted in the installation and layout of factory lighting:
- Installed lamps should maintain an appropriate safe distance from combustibles (generally not less than 0.5 meters) and must not be close to combustible or flammable materials. (Explosion-proof anti-glare lamps)
- Lighting fixtures should be installed on non-flammable bases. It is strictly prohibited to use paper, cloth, or other combustible materials as lamp shades. JY6130 (square explosion-proof floodlight)
- When selecting wires, attention should be paid to their insulation strength and cross-sectional specifications, especially for temporary lines. Random wiring should be avoided to prevent short circuits caused by damaged wire insulation layers, which may lead to accidents. (LED industrial flying saucer lamps)
- Select safety fuses (devices) that meet specifications. The fusing current of the fuse should be greater than the rated current. It is forbidden to arbitrarily increase the fuse size or replace it with iron, aluminum, or copper wires. This prevents fire accidents caused by fuses failing to blow when wires or lamps have faults.

- When installing lamps, a certain safe distance should be maintained from combustible ceilings and other objects, ensuring good heat dissipation and ventilation conditions. Dust on ballasts, starters, and other parts should be cleaned regularly. The power must be cut off when the lamps are not in use or when no one is present. Meanwhile, the lamps should be kept dry to prevent moisture intrusion or dampness.
