An LED is a semiconductor that emits light when it is sent in the right direction flow through it. Thus, it is an electronic component that emits light directly. The color of light depends on the semiconductor material used. An LED is composed of a chip of luminous material, a lead frame with place for the chip and a housing which protects the chip.

LEDs are small about (2-5mm) and combined they give off a lot of light. One of the properties of a diode is that it is in on the one hand guides the electric current, and stops in the other sense. So if you for example would be a wrong LED connect the flow will be stopped and will not burn. The LED These are basically not broken. |
