Due to the low temperature and high humidity environment, the cold storage requires certain characteristics of the lamps used in it, and the LED special cold storage lamp came into being. There are also special requirements for lighting in food processing, refrigeration, cold chain logistics, fresh supermarkets and other fields. Among them, the requirements for lighting in food processing workshops that colleagues in the industry are more concerned about.

What is certain is that high temperature light sources such as explosion-proof lamps, energy-saving lamps, and incandescent lamps are not suitable for use in food processing workshops. Especially not suitable for refrigerated food.

On the other hand, in the food processing workshop, the hygiene requirements of raw and finished food are very high. "It is not allowed to corrode the lamps, or the bulbs burst, etc., to prevent dust, glass fragments, etc. from falling into the food, causing pollution and endangering food safety." In fact, after years of product promotion and market guidance, now food factories generally use LEDs Lamp lighting, but the vast majority of food factories are unaware of the different needs of the environment for lighting lamps.

"At present, few food manufacturers have proposed that we have found in practice that the composition of the air is different, the actual environment of using the lamp is different, and the requirements for the lamp are also different. We found this problem from a customer of a food factory. He is making dumpling fillings and pickles. The air in the workshop is very salty. Almost all metal products will be corroded and rusted, and lamps are no exception. We have specially developed a three-proof lamp for this purpose. All are plastic materials.” There are also some food factories with a lot of steam, so the humidity is very heavy, even if the high-power white light is used, it is still difficult to see, because the white light is strongly reflected in this environment, which is very dazzling. If you choose yellow light, the light is soft and the penetrating power is strong, and you can see it more clearly; for example, the air humidity in the workshop of seafood and noodle products is high, and the water resistance is very high. Fresh supermarkets also have different requirements for the color of lamps, and the color of lamps will be set according to the different colors of food.

All in all, before the selection of lamps and lanterns was only based on the size, height, old and new, and material of the cold storage. In the future, it may be necessary to choose suitable lamps and lanterns according to different product characteristics. It is not too difficult to solve the technical problems of various types of lamps, mainly because of the experience accumulated for a long time, different lighting solutions can be proposed for different food production environments.
