Functional description Light emitting diodes are modern semicon- ductor devices. duced, sandwiched between positive and a negative substrate inside the LED. Their very long service life over 10000 hours demands optimised thermal management order prevent overheating. Actual coloured light produced, depending on which materials are chosen. The smallest LED chips have side length approx. 250 micrometre = 1 one thousandth millimetre). They are completely superseding traditional light sources many applications. mix- ture RGB (red, green, blue) also produces white.95 The Lighting Handbook Light emitting diodes (LEDs) – Very efficient light production – Wide selection standard ranges – Can switched and dimmed required – Very long service life – Good very good colour rendering – Very good production coloured light – Use: LEDs can used for both functional and decorative lighting indoor and outdoor locations. Today, LEDs are already some the most efficient light sources for general lighting. . rule, they are powered via appropriate convert- ers. Nowadays, high- quality white light produced blue LEDs with yellow luminescent substances. Their characteristics are determin­ ed their materials, mechanical design and operating mode.
