Recently, the renovation of the lighting of a boiler factory in Sichuan was successfully completed. The lamps were bright, and the workshop became bright and bright, sweeping away the darkness of the past.

There is a problem before the transformation

The workshop lighting used in the factory originally used 280 sets of 400W traditional metal halide lamps. Metal halide lamps have high energy consumption, uneven illumination, and dim light in the workshop, which seriously affects workers' work efficiency and enthusiasm. Not only that, the light decay of the luminaire is more serious, the life of the light source is short, the luminaire is easy to damage, and the maintenance is large.

The person in charge of the workshop lighting hopes to increase the illumination by more than one time through a complete set of lighting solutions, providing workers with a good lighting environment and saving electricity.

Lighting renovation program

In response to customer requirements, Grand Technology (overclocking three customers) proposed a system lighting renovation program. After comprehensive consideration, Grand Technology replaced the original 400W metal halide lamp with a 200W LED high bay light. The installation height was 11 meters and the number of lamps remained unchanged at 280 sets. Grand Technology uses the overclocked three GK200C high bay light kit, which has excellent heat dissipation performance, reasonable optical design and high quality to meet the customer's lamp requirements.

Overclocking three GK200C high bay light kit

The overclocking three GK200C high-altitude lamp kit uses heat pipe riveting technology to transfer the heat generated by the light source to the modular heat sink through the high-efficiency heat pipe, which quickly reduces the temperature of the light source and prolongs the service life of the light source.

The pure copper heat pipe and the heat source are zero-distingly bonded, and the heat generated by the light source is quickly transmitted to the modular heat sink, which greatly improves the heat conduction effect.

Analysis of the effect of lighting renovation

After the renovation of the luminaire, the average illuminance of the workshop increased from 98lx to 425lx, and the illuminance increased by 3.33 times. The illuminance uniformity increased from less than 0.2 to 0.46. The visual comfort of workers has a large Improve; the color rendering index is raised from below 30 to over 70, the color is highly consistent, and the color is more realistic.

Not only that, the annual light decay rate of metal halide lamps is above 10%, and the life of lamps is short (about 3000 hours). The annual light decay rate of LED industrial and mining lamps after renovation is less than 1%, the service life is more than 10,000 hours, and the service life is improved. More than 3 times, the lamp replacement cost and labor cost are greatly reduced.

Energy saving analysis

Through a complete set of lighting renovation solutions, the lamp power was reduced from 400W to 200W, and the total power of the workshop was reduced from 112KW to 56KW, a reduction of 56KW.

According to the calculation of 20 hours per day, it can save 480,800 kWh per year and save 50%. It is understood that the local electricity bill is 0.82 yuan / kWh, which can save about 335,000 electricity bills per year, greatly reducing the electricity bill.
