LED lighting guide: How to light your factories with LED lighting


By BizLED Bureau

Nowadays, industrial divisions such as factories are opting for LED lighting as it offers a number of benefits over traditional form of lighting. However, before making the switch to LED lighting, there are a couple of factors that need to be taken into consideration in order to experience better and quick results.

Some common industrial lighting concerns

Factories typically house huge machineries and big highbay lights used to light the entire place. But, it was a difficulty to get access to such lights that were placed at a great height and thus, it was quiet complicated to maintain them. Furthermore, replacing the lights at height was an issue.

Majority of the highbays employed HID lamps. High pressure sodium consisted of good lamp life, maybe 25,000 hours. However, the color interpretation was quiet poor and below par.

Why LEDs emerge as the clear winner?

LED lights have simply changed the face of industrial lighting. Since they have long life, cost of maintenance gets reduced significantly.

There are additional savings in factories that operate 24/7; you don’t have to bear the massive cost of stopping a production line only to replace a lamp.

One portion of industrial lighting that is frequently forgotten is that the ambient air temperature about a highbay might be significantly higher than at a “normal” ceiling height. It is indeed sensible to check the temperature at the height the luminaires are to be set up. In industrial areas, one can employ a light source with a lesser CRI than normal, relying on the use of the room.

For higher roofs, 180W circular highbay unit will be more appropriate. It resembles the appearance of a traditional HID highbay but a lot shallower. It is planned to be a direct substitute for a 250W metal halide luminaire hence offering longer life and around 30% energy saving.

Sometimes you require light from floor to ceiling however, for this specific application, you may use reflector which tapers the beam from the regular 110° to just 60°.

One of the ideal ways to conserve energy in a factory is to use controls. It is suggested that you can use a simple occupancy sensor for places that are not used frequently. This only switches On/off. Nevertheless, for active areas, the sensor makes use of step dimming. When there is no movement, the sensor detects it at once and thus, goes on to dim the luminaires to 10% – 50% of total output. This helps in retaining a low level of lighting for safe movement. You can use the sensor up to 15m heights..
