LED ( light-emitting diode ) = light diode, is a luminous object which is integrated into light bulbs and various other light fixtures = lamps. LED lamps have a lifespan and energy efficiency which are several times higher than those of incandescent light bulbs, and considerably higher than in most fluorescent lamps.
The main advantages of LED lamps are:
- Energy-efficient – LED lamps can emit more than 135 lumens / W;
- Long lifespan – 50,000 work hours or more;
- Initial ignition without warm-up – an LED is lit immediately – in a nanosecond;
- Works at low temperatures, even below zero;
- Excellent colour rendering – LED does not cause discoloration, like other light sources, such as fluorescent lamps;
- Environmentally-friendly – LED does not contain mercury or other dangerous substances, and does not emit IR and UV radiation;
- With LED lighting one can control light intensity and colour.
LED lighting has numerous outdoor and indoor applications. It is used as one of the solutions in illuminating:
- Restaurants and hotels;
- Residential lighting;
- Stores, supermarkets;
- Public lighting, playgrounds, parking lots;
- Industry and warehouses;
- Roads and highways;
- Public, educational, health care institutions,
