LED is a light-producing semiconductor which discharges light when electric current moves through it. The electrons present in the semiconductor get attached with electron holes and release photons (energy). The shade of the light is dictated by the vitality required for electrons to overcome the bandgap of the semiconductor. White light can be generated by a film of a light-emitting phosphor on the device.
The earliest LEDs, which was developed in around 1962, used to emit infrared lights of low intensity. Infrared LEDs have found its use mostly in remote control circuits which can be found in equipment linked with consumer electronics. Modern LEDs come with ultraviolet, infrared and visible wavelengths with the high light output.
LEDs have several advantages over an incandescent light. They are:
- Long Lifetime
- Small Size
- Fast switching
- Improved physical robustness
LEDs have found its use in automotive headlamps, traffic signals, plant growing light, aviation light, medical devices, lighted wallpaper, camera flashes, plant growing light, and advertising.
In contrast with a laser, the light that is released from an LED is neither highly monochromatic nor spectrally coherent. Still, its spectrum is adequately narrow that it can be recognized by the human eye as a saturated color.
Standard LEDs – Through Hole
LEDs are available in several different sizes and shapes. The category of LEDs that you will be using most is the through-hole LEDs with 2 legs. There are multiple LEDs that are hard and small to solder but these are simple and easy to use along with a breadboard provided that are available with long wires you can stick in. The light emitter is defended by a clear bulb. Consistently, through-hole LEDs have overwhelmed the market of high-brilliance LEDs, in light of their exceptionally intelligent structure with essential optics.
LED lamps or through-hole LEDs have mostly found its use in outdoor applications as they provide multiple benefits over standard surface mount (SMT) LEDs. Let's have a look at some of the characteristic feature of Through-Hole LEDs:
- They are brighter.
- They are very clear.
- They are available either as tint-diffused or tinted for higher contrast ratios.
- They have a diverse range of essential optic design.
Due to the availability of primary optics, LED lamps or through-hole LEDs are considered as one of the best choices regarding definition, brightness, and controlled viewing angles.
