How are factory lamps configured?

(1) Factory lighting must meet the needs of production and inspection. The lighting system of the plant is generally divided into two categories: for tall plants with a height of more than 15 meters, gas discharge lamps are generally used as roof light sources, and lamps with narrow beams are hoisted at the bottom chord of the roof truss. Floodlight fluorescent lamps can be set on the wall and column, and the combination of the two can ensure the required illuminance on the working face. In general plants, high-power fluorescent lamps should be used as the main light source. The arrangement of lamps can be vertical or parallel to the beam.

(2) The following principles shall be followed when selecting enterprise lighting fixtures:

① Convenient maintenance and safe use shall be considered.

② In the workshop with explosive gas or dust, dust-proof, waterproof or explosion-proof lamps shall be selected. Control switches shall not be installed in the same place. If they need to be installed in the same place, explosion-proof switches shall be used

③ In damp indoor and outdoor places, closed lamps with crystal water outlet or open lamps with waterproof opening shall be selected.

④ Floodlights shall be used in hot and dusty places.

⑤ Sealed lamps shall be used in the room with corrosive gas and especially damp. All parts of the lamps shall be subject to anti-corrosion treatment, and the switchgear shall be equipped with protective devices.

⑥ For rooms with dust, fully enclosed lamps shall be used according to the amount of dust discharged and its nature.

⑦ Lamps with protective net shall be used in the workshop where the lamps may be mechanically damaged; Lamps with shockproof devices shall be used in vibration places (such as places with forged bell, air compressor and bridge crane).

⑧ Bakelite lamp caps shall not be used in sealed lamps and bulbs larger than 150 watts, but porcelain lamp caps shall be used.
