Light source lighting is required wherever people appear, and lighting sources are often divided into hot light sources and cold light sources from the principle of light emission. The current incandescent lamps, metal halide lamps, and energy-saving lamps are basically thermal light sources, and the main energy consumption is heat, not light; LED light sources are different, which belong to the principle of electronic motion lighting, and the luminous efficiency is very high, and the lower the temperature, the higher the luminous efficiency. In the environment, the better the luminous characteristics are.

The main characteristics of the cold storage are: low temperature (-45 degrees - 15 degrees), more than 98% humidity, freezing phenomenon, belonging to the special electricity and lighting places stipulated by the state, some quick-freezing cold storage, often the temperature is low and the humidity is high , has higher requirements for lighting.

Requirements for lamps used in food processing workshops

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. 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. 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 in this environment, the white light is strongly reflected and very dazzling. If you choose yellow light, the light is soft and smooth. If the penetrating power is strong, you can see it more clearly; for example, the air humidity in the workshop of seafood and noodle products is high, and the waterproofness 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 LED cold storage lamps according to different product characteristics.
