Need to keep the food fresh and warm while preserving its safety and nutritional value.

In general, when food is displayed at high-end restaurants, buffets, and fast food restaurants, IR lamp is used not only for keeping food warm, but also for the effect of making food look more appetizing through the light. As the surrounding temperature gradually decreases, the fat hardens and the food becomes hard. Infrared bulbs are used to prevent this and preserve the texture of the food.
