Components of a complete LED module. Completel LED modules consist of LED modules, various covers as well as integrated heat sinks. Depending on requirements, there are the covers in different models: diffuse, clear, prismatic or with optics. Detailed display of a complete LED module based on the example of LINEARlight.
Simple LED (Light Emitting Diode) circuit diagram. In electronics, an LED circuit is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. The voltage drop across an LED is approximately constant over a wide range of operating current; therefore, a small increase in applied voltage greatly increases the current.
