LEDs have been widely used in freezer lighting and are increasingly being used in low temperature freezers and even for illuminating fresh food. LED lighting is currently being used in a large number of lighting for frozen foods.
If an inefficient lighting fixture is used, in addition to the energy consumed for lighting, the large amount of heat generated by it will require a refrigerator system to cool, which will result in wasted power. LED lamps and other semiconductor devices are capable of high luminous efficiency and can operate at lower temperatures for a long time.
Ireland's Nualight said the current market value of the retail food lighting market reached $1 billion. The retail food lighting market will be a promising market. According to Liam Kelly, CEO of Nualight, the market is very large and active. Nualight has grown at an annual rate of over 100% in the past few years.
Liam said: "So far, the focus is on lighting systems for refrigeration cabinets and refrigerators. I hope LEDs will replace fluorescent lamps in lighting applications in refrigeration cabinets. In recent years, including Wal-Mart, Tesco, Kroger and SUPERVALU. Large food retailers around the world have replaced fluorescent lighting with LEDs in their frozen food cabinets, saving up to 70% in energy.
