Applying polar bear fur to refrigerators!?

The fur of a polar bear, also known as a white bear, is actually not white, but colorless and transparent with a hollow center like a straw. When light hits the fur, it reflects in various directions inside the hair, making it appear white.

This structure of polar bear fur is applied to the LED lamp cover inside refrigerators. By making the center of the lamp cover concave, the direct LED light is scattered in various directions. This is designed to brighten the back of the refrigerator while ensuring it is not dazzling to the human eye.
