In food lighting, it is particularly important to emphasize the quality and freshness of the product, the correct lighting design should be through accurate design, fully show the inherent color of the item, so that they look more delicious. This is an "honest" use of light, not a "touch up".

Food is displayed in the grocery store, and the freshness of all products must be emphasized. Light as an important promotional tool, should be able to perfectly highlight the characteristic color of the food. The light source with high color rendering and the "right" light color can make the color of the displayed food show without distorting it. Another crucial consideration is the properties of the food itself, their sensitivity to heat, infrared (IR) and ultraviolet (UV) rays, etc.

For example, light sources with more blue light components emit higher energy than those with more red light in the spectrum. In addition to using filters, adjusting illumination and exposure time can also help with food safety management.

Consumers want an "honest" light environment, and people are willing to come back and shop happily, not only because of the quality and freshness of the product, but also because the light environment here is right. Making the product look better than it is will only give you short-term profits.

But LED, as a new light source solution, has made rapid progress in the field of food lighting. Its advantage is that the light basically does not contain infrared and ultraviolet rays, and the color of the light can be customized according to different food types. In addition, it has the advantages of excellent low temperature starting performance, long life, low light pass attenuation, and diversity. In addition, the frequent switching of the LED does not affect the life span, and can be activated instantly - which makes it useful for emergency lighting.

It is because of these characteristics that LED has won itself a place in the field of food lighting. As well as being used in freezers for milk, pre-packaged meat and cheese, they can also make fruit and vegetables and baked goods look more palatable. In these places, the characteristic light color shows its unique potential. The red color of meat and sausage is emphasized while the white color containing fat is still visible; The bread and rolls looked freshly baked in the golden light; The fresh fish placed on the ice bed became the shining star under the cold white light.
