So what are the advantages of cold storage lamps compared with traditional lamps? Regarding this issue, I have to talk about the lighting principle of cold storage.

1. The principle of library lighting

After inputting a certain range of power supply voltage, the high-frequency generator generates a high-frequency constant voltage and sends it to the power coupler, and the power coupler establishes an electrostatic strong magnetic field in the discharge space of the glass bulb.

It ionizes the atmosphere in the discharge space and produces strong ultraviolet light, and the three-color phosphors on the inner wall of the glass bulb are excited by the strong ultraviolet light to emit light. After understanding the principle, then look at the application specifications of LED cold storage lights in specific scenarios.

2. The specifications of lighting lamps are as follows:

Take the large LED cold storage lamp as an example: the lighting adopts aluminum alloy shell, and the low temperature LED cold storage lamp shell has high explosion-proof performance. The 30W LED cold storage lamp can replace the 300W incandescent lamp or the 150W metal halide lamp. Scope of application: low temperature warehouse for petroleum products, large logistics storage cold storage, chemical cold storage;

Generally, the LED cold storage light is divided into two parts, one part is the protective cover, and the other part is the light source. Now the protective cover is divided into material, there are cast aluminum + glass, iron + glass, all plastic. For example: LED cold storage lighting, some small cold storage can use LED lighting, LED lighting has a longer service life than traditional, safe and environmentally friendly.

The lamp housing is made of low-shrinkage unsaturated polyester glass fiber reinforced molded plastic, and has a moisture-proof and explosion-proof design, which is very suitable for low temperature in cold storage.

LED cold storage light sources include traditional incandescent lamps, traditional energy-saving lamps (fluorescent lamps), metal halide lamps, etc. It is recommended that you can buy them from relatively standardized manufacturers, and after-sales are guaranteed.

3. Other specifications:

Emergency lighting should be arranged in the high and low voltage power distribution room. When the power distribution room is equipped with a DC power supply panel, the emergency lighting power supply can be taken from the power supply panel, otherwise the emergency lighting fixture with its own battery pack should be used. The duration of emergency lighting should not be less than 30min.

The lighting method of the ammonia compressor room should be general lighting, and the illuminance design should be 50~75lx. Explosion-proof fluorescent lamps should be used, and explosion-proof incandescent lamps should also be used in the operating platform part of the equipment room. The lighting circuit should use copper core insulated wires with a cross-section of not less than 1.5mm2 to pass through the steel pipe and lay it openly. 

Ammonia compressor room should be equipped with emergency lighting, and explosion-proof emergency lighting lamps with battery packs can be used. The duration of emergency lighting should not be less than 30min

The arrangement of lighting fixtures in the cold room should avoid ceiling-type air coolers (cooling fans) and top row pipes, and focus on the lighting in the aisles in the warehouse, which can be evenly arranged in the cargo space.

The lighting switch in the cold room should be a moisture-proof switch or an airtight switch. The lighting switch of each warehouse should be centrally installed outside the door of the warehouse, and should be arranged away from the door.
