The history of LED lighting (LED = Light Emitting Diode) began with the discovery of the physical effects of electroluminescence by the Englishman Henry Joseph Round in 1907, but it was not until 1962 that the first industrially manufactured LED lights came onto the market. At the beginning of the 1970s LED lights were available in a variety of colours (red, yellow, green, orange). White LED lights first became available in 1997.
LED lights last approximately 35,000 hours and use very little energy, which makes them one of the most economical light sources available today.
LED lights are used for a wide range of applications, including the automotive industry, effect lighting, and signalling systems. Due to the cost savings over the life of the lamps, LEDs are an exciting option for use in private residences.
Advantages of LED Technology
- Low energy consumption: LED lights save up to 80% energy
- Very long service life: up to 35,000 hours
- Very bright: LED lights available with > 1,000 lumen output, an alternative to 75W light bulbs
- Appealing colours available: e.g., 2,700 Kelvin (warm white)
- Instant on: emits full brightness immediately after being switched on
- Contamination-free: no infrared or UV radiation, no mercury
- Cutting-edge design: new design possibilities due to compact dimensions
- Robust: vibration and shock resistant
- Cool operation: When switched on, LED lights do not emit any heat
