Can LED light bulbs: Also known as recessed lights, can light LED bulbs fit into sockets – or cans – mounted in the ceiling. Flood LED light bulbs: Flood bulbs are designed to emit a strong but wide beam of light to illuminate a broad area. They’re mainly used in exterior applications. LED lights, or "Light Emitting Diodes," as they are better known, emit a continuous spectrum. The spectrum they cover is not as broad as other colored lights or incandescent lights. Basics of LED (Light Emitting Diode) As mentioned in the introduction, an LED is a semiconductor light source. It consists of a PN Junction Diode and when voltage is applied to the LED, electrons and holes recombine in the PN Junction and release energy in the form of light (Photons).

You’ll find many statements on the internet stating that “LEDs have no UV 2021-04-10 · LED lighting differs from incandescent and fluorescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer. LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions. Point lights are useful for simulating lamps and other local sources of light in a scene. You can also use them to make a spark or explosion illuminate its surroundings in a convincing way.

However, since the advent of white light LEDs, this has changed. White light LED bulbs are created by coating brilliant blue LEDs in phosphor. This allows the blue to be absorbed and only allow the white to come through.
