LED Lights: A Quick Overview To Get You Started

A LED (light-emitting diode) is a light source. It was created in the early 20th Century, but was not introduced as a practical electronic light source until 1962. The early versions of LED lights emitted a low-intensity red light, but modern LED lights are available in various intensities, wavelengths, and high brightness.

The semiconductor diode is the basis for LED lights. When the diode is switched on, electrons recombine and the energy produced in this process is released as light. This is called electroluminescence. The energy gap of the semiconductor determines the color of the light. The cool thing about this process is that it can be done in the small area of the LED bulb.

LED lights have many advantages over traditional lighting options. They use less energy, have a longer life span, perform just as well as traditional light bulbs, and are much smaller than traditional light bulbs. However, they are relatively expensive and require to precise conditions to perform optimally.

LED lights can be used in various capacities. They are used in the majority of solar lighting fixtures and in many low voltage lighting fixtures. Overall, they are used as low-energy alternatives for traditional light bulbs in common lighting fixtures (house lamps, yard lamps, car lights, etc.). They compact nature of LED lights also allows them to be used in video displays. Furthermore, they are use in communication technologies due to their high switching rates.
