Light emitting diodes, LEDs, have extremely long life, impact resistance and low energy consumption. When dimmed, the light color remains constant. When connected to the mains, they require control gear to ensure the correct operating current. The point light source provides for precise light control while the plastic encapsulation of the diode acts as protection and lens. The output of the LED decreases with increasing temperature. Consequently, good heat dissipation is important for smooth operation. Direct solar radiation should be avoided so too installation near other sources of heat. With an average rated life of 50,000 hours, LEDs are suitable for long operating times. As they start instantly and react directly to control, they are ideal for quick, dynamic light scenes. The development of LEDs currently focuses on more compact shapes, a higher luminous flux, and better luminous efficacy as well as a more economical production process. A further goal is the reduction of production-related color deviations. Manufacturers sort LEDs by luminous flux and dominant wavelength and give them a bin code and a rating. This sorting of LEDs is called binning.
