When the light used in cold storage like cooler, freezer warehouses etc, ordinary lights have many defects such as high power consumption, low illuminance, short life, and poor sealing, which will lead to air leakage and water freezing in the cold storage light. Once a large amount of water accumulates Freezing will lead to short circuits and cause food safety hazards. In addition, ordinary lighting is prone to cracking and damage when used in a low temperature environment. Before the appearance of cold storage lamps, ordinary incandescent lamps, energy-saving lights and a moisture-proof lampshade were used for cold storage lighting, or explosion-proof lamps were used instead. Using ordinary incandescent lamps and energy-saving lamps with a moisture-proof lampshade, this configuration is very frequently damaged in low-temperature cold storage! Even one broke in a few days. There are also some large cold storages with a height of more than ten meters. Incandescent lamps and energy-saving lamps are not enough. Because the brightness is not enough, ordinary lamps cannot replace the special lamps for cold storage. LED cold storage lamp solves these problems. The cold storage lamp can be used for a long time in the environment below -50 °C, and has a long life. Good efficiency and so on. It can be said that the LED cold storage lamp is a typical environmentally friendly, healthy and promising cold storage lighting source product, and it is one of the preferred light sources at present.

The main characteristics of the cold storage place are under low temperature, high humidity and freezing phenomenon, so the cold storage lights must  be used according to the standard protection level. Whether it is an old cold room or new, incandescent lamps or energy-saving lamps with low luminous efficiency and short life are used as lighting fixtures in the warehouse. The "Refrigeration Storage Design Specification GB50072-2010" issued by the state has clear regulations on the electrical lighting system of the cold storage, and the contents are as follows: The lighting fixtures in the cold room should be moisture-proof incandescent lamps with an enclosure protection level of IP54 and a protective cover. The illuminance of lighting in cooling rooms, cold junction rooms, refrigerated rooms, freezers and halls should be over 20 lx; ​​the illuminance of lighting in processing rooms, packaging rooms should not be lower than 50 lx. The arrangement of lighting fixtures in the cold room should avoid ceiling-type air coolers (cooling fans) and top-row pipes. Lights should be placed on the aisles in the warehouse, and they can be evenly arranged in the cargo space.

As ammonia is used as refrigerant in the refrigeration system, and ammonia is toxic and explosive, according to the "Code for Design and Installation of Explosion and Cold Storage)) (GB50058--92), the ammonia compressor room and equipment room belongs to the explosion hazard area. Ammonia gas is lighter than air. In the event of an ammonia leakage accident, ammonia gas will accumulate in the upper space of the ammonia compressor room. Therefore, the selection and wiring requirements of lighting fixtures should be designed in accordance with the relevant regulations for explosion-hazardous areas. In addition, the cold storage lamp has a good waterproof level, and must reach to IP65 waterproof level (that is, it can completely prevent dust from entering, and at the same time, it has no effect on the low-pressure spray of rainwater at any angle). According to the requirements of electronic components, belong to industrial-grade products, cold storage lights must resist the interference in the power grid.

So, how to choose the right LED lights for your cold storage facilities like Cooler/Freezer Warehouses.

The selection of cold storage lamps is usually based on the wattage, the irradiation area, the voltage, the material, the waterproof level, the working environment temperature, the working environment humidity, the applicable height, the cooling method and other parameters. The common usage scenarios of cold storage lights are as follows:

1. Air-cooled ceiling cold storage lamps Ceiling cold storage lamps are suitable for use in air-cooled cold storages. Generally, a small cold storage can be installed with 10-20W. The common shapes are round, oval, rectangle, square, etc.

2. Aluminum row boom cold storage light The boom cold storage lamp is suitable for the aluminum row storage cold storage lamp. This kind of aluminum row boom, the boom standard is 20cm, and can be customized according to requirements.

3. The ceiling-mounted high-penetration cold storage lamp transparent cover cold storage lamp has strong penetrating power and is suitable for cold storage with high fog and high humidity, especially cold storage with medium temperature and low temperature, but its disadvantage is that it is dazzling, for example, when lifting goods It is dazzling, and it is not suitable for personnel to work in the cold storage for a long time.

4. The cold storage light in the cold storage production room The cold storage lamp for the workbench in the cold storage production room generally has two kinds of milky white cover and transparent cover. The milky white cover is not dazzling, but the penetration is not as good as that of the transparent cover cold storage lamp. Although the transparent cover cold storage lamp is dazzling, the penetration is very good. For this kind of situation, we recommend the led high bay light for cold room which is from LONG SUN optoelectronics.

The power range is from 100-250W, which is enough for some large cold room. Also, the linear high bay is required for cold storage.

5. Other cold storage lights require other cold storage lights, such as floodlights, etc. At present, the above 4 kinds are mostly used in the market, and we can choose according to requirements. But no matter what you choose, the cold storage lamp must be resistant to low temperature, waterproof, dustproof, and explosion-proof, otherwise the service life is very short. It is reported that in order to further expand the market, the cold storage light from LONGSUN is under production. Their high-end cold storage lamp beads and electrical components are all imported, which can greatly improve the service life of the cold storage lamps. The housing is guaranteed by integrated flame retardant materials. It is safe to use, and the gaps of the cold storage lights are sealed with imported silicone, which ensures that the cold storage lights can also play a "waterproof, dustproof and explosion-proof" effect in an ultra-low temperature environment of minus 50 degrees.
