Red led material

WebDie Kurzbezeichnung LED ist die Abkürzung für "Light Emitting Diode", was auf Deutsch "Licht emittierende Diode" bedeutet. Sie werden als Signal- und Lichtgeber in unterschiedlichen Bereichen eingesetzt. Leuchtdioden gibt es in verschiedenen Farben, Größen und Bauformen. Die gebräuchlichsten Bauformen haben einen 3 mm oder 5 mm großen ... WebAn LED is a type of p n junction diode that works on the principle of electro-luminance. A material called electro-luminance is used to convert electrical energy into light energy which later helps in the propagation of light energy. When light is emitted in the front bias, it is called a light-emitting diode.
