LED - Design and Functionality
LEDs are tiny in size yet great in performance. They combine various technologies in a very smallest space. Here you can learn more about the design and functionality of these innovative "mini lights".LED Design
LED lights and LED systems basically consist of three components:
- Component 1: The LED
The LED chip is at the core. To protect it against environmental influences, the chip is mounted in a housing. This housing also determines the LED’s radiation pattern through the primary lens.
- Component 2: The circuit board
The individual LEDs are mounted on the circuit board. The LEDs are bonded to the control electronics through the conductors. The substrate ensures the heat dissipation.
- Component 3: The secondary optics
Secondary optics such as lenses, reflectors or diffusers are mounted on the circuit board and complete the LED solution.
LEDs convert electrical energy – in other words electricity – into light. Professionals call this process "electroluminescence". Even a small amount of energy is sufficient to make the semiconductor emit light. LEDs can switch very quickly from emitting light to not doing so. The LED light can be clocked into the MHz range. The human eye cannot register such high speeds – the light is therefore perceived as diminished, depending on the duty cycle. This effect is used for dimming LED lights through Pulse-Width Modulation (PWM).
