Technical Notes What is an LED? LED stands for Light Emitting Diode, short luminous diode. In contrast to conventional lamps like incandescent, Epoxy halogen or discharge lamps, the light of LEDs is generated in tiny electronic chips. These chips are made of semiconductor crystals embedded in a plastic case. This plastic case ensures protection from environmental influences as well as improves the photometric properties. LEDs are regarded as extremely long-life and efficient, due to many different Cathode Chip types and light colours they are suitable for a great variety of applications. Bond Wire Cooling surface Reflector Anode The light of an LED In the p-n-junction or depletion layer (an area within the chip) the light is generated. The process is called electro-luminescence. Depending on the semiconductor material the colour appears, there are LEDs in red, yellow, green, orange and blue. White light For the generation of white light with LEDs, there are two different possibilities. First, the blue light of an LED is transformed to white light by luminescence conversion like in fluorescent lamps. For this process a very thin film of yellow phosphor material is applied to a blue LED chip. The second method, however, generates white light by additive colour mixing. There, a minimum of three LED chips is needed, at least red, green and blue (RGB). Service Life Luminous diodes distinguish themselves by an extremely long service life. But be careful: when the temperatures are too high this service life can be shortened dramatically. So, for a long life optimal thermo management must be applied. Service life of LEDs is mainly defined by loss of light (degradation) during the burning hours. Due to material fatigue and other influence factors an LED looses light during its life cycle. In most cases, the time when light is down to 70% is quoted as service life. Failures, however, cannot be ruled out as impossible. rel. luminous flux 100% 90% 80% 70% 60% 50% 1 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 400 nm 450 nm 500 nm 550 nm 600 nm 650 nm 700 nm 750 nm Spectrum LED (warmwhite/ 3 000K) 40% 0 50 000 hours of operation Luminous Efficiency Thermo Management Light Distribution How efficient a light source might be can be described by the luminous efficacy (lm/w). Highly efficient LEDs achieve luminous efficacies of more than 100 lm/w even today and so belong to the most efficient light sources. Luminous efficacy depends on many factors: design and generation of LED, optics (lens and reflector), ambient temperature, ballast, driver and many more. The main focus must be put to the temperature of the chip. Similar to the span of service life, luminous efficacy goes down with rising temperatures. For their efficiency and longevity LEDs need to get the generated heat out of the chip and release it to the environment. How good this process works is determined by thermo management. The LED itself is referred to a cold light source. This means, that there is no IR radiation in the light bundle. And not, like many people would think, that it would not generate any heat, on the contrary. How much heat it produces depends on power and efficiency. LEDs originally offer directional light due to the casing design. This property makes luminous diodes interesting products for all kinds of applications where things depend on precise illumination. 2
