Many people have such questions: What kind of lights are used in cold room? Will ordinary lights be frozen?
People usually use cold room to store food or other materials to prevent spoilage. The temperature inside the cold room is relatively low and can be frozen, and the humidity inside is relatively high.
The inside temperature of the cold room is too low compared to the normal temperature. If use ordinary lighting lamps, incandescent lamps, their lifespan will be greatly shortened in the severe cold environment. Meanwhile, the light of ordinary lamps appears a little soft in the cold room and is not bright enough.
What is Cold Room Light?
Cold room light is one kind of light named by the purpose, which is used in places such as freezing and refrigeration where the ambient is low temperature, high humidity, and should pay more attention to electrical safety and environmental protection.
Cold room light has two main components: protective cover and light source. The protective cover is made of PP (Polypropylene), PC (Polycarbonate), cast aluminum, glass, ABS and other materials; the light source normally is LED.
Why Need Cold Room Light?
Ordinary lighting has many defects when used in cold room, such as: high power consumption, low illumination, short life, poor sealing, which will lead to air leakage and water accumulation finally freezing in the light. Once a large amount of accumulated water freezes, it will cause short circuit, and safety hazards. In addition, ordinary lighting is prone to cracking and damage when used in low temperature environments.
LED cold room light solved these problems. Cold room light can be used for a long time in an environment below -50℃, and have a long life. They are “moisture-proof”, “dust-proof”, “explosion-proof” and “low-temperature resistant”. They also have uniform illumination and good luminous efficiency at low temperatures.
Cold Room Light Selection
The selection of cold room lights usually depends on the lamp power, irradiation area, voltage, material, waterproof level, temperature and humidity, etc.
Based on these, in order to extend lifetime of the cold room light, you also necessarily choose lights which are resistant to low temperature, dust-proof, and crack-proof.
Cold Room Light Parameter
Voltage: 220V~50/60Hz
Power: 20W/24W/30/35W
Water-proof Grade: IP65
lumen: 2000/2400/3000/3500
Set Temperature: -50°C ~ 40°C
Cold Room Light Classification
1. Air-cooled ceiling cold room light
Ceiling cold room light is suitable for air-cooled cold room. Generally, small cold room can install 10~30W light. Common shapes include round, oval, rectangular, square, etc.
2. Aluminum hanging rod cold room light
Rod standard length is 20cm. Length can be customized according to customer requirements. These lights have three shapes: rectangular, square and round, all are 30W.
3. Ceiling high penetration cold room light
The transparent cover cold room light has strong penetration and is suitable for cold room with heavy fog and high humidity, especially medium and low temperature cold room.
4. Production workshop cold room light
The workshop and workbench used cold room light, which generally use milky white cover or transparent cover. The milky white cover is not dazzling, but the penetration is not as good as the transparent cover light. This kind of lamp is bright enough, illuminates a wide range, full-circle light, covers multiple corners, low light decay, and has a long life.
5. Cold room floodlight
This light has extra-thick glass masks that aren’t easily damaged, is high light transmittance, uniform light emission, and soft light. They are made of high-quality die-cast aluminum forging, not easy to deform, corrosion resistance, and has adjustable brackets to adjust the lighting angle according to needs.
Conclusion
When choosing cold room light, you must choose professional, regular and qualified light. Don’t select unqualified cold room lighting fixtures because of cheap pricing, which will leave hidden dangers for the safety lighting of the cold room in the future.
