How Does LED Lighting Work?
LED lighting works by passing an electric current through a semiconductor material, which then emits light (photons) and produces illumination with varying degrees of brightness measured in lumens and color temperature measured in kelvin.
When an electric current is applied to a semiconductor in an LED fixture, it causes the electrons to move around within the material. These energized electrons release energy in the form of photons. The specific semiconductor material used determines the color of the light emitted. By controlling the composition of the semiconductor, manufacturers can produce LEDs that emit various colors of light.
The brightness of an LED light is measured in lumens. Lumens indicate how much light is produced by the fixture. Therefore, the higher the lumen output, the brighter the light will be. On the other hand, the color temperature of LED light is measured in kelvin, which signifies the warmth or coolness of the light. Warmer temperatures, around 2700-3000 kelvin, produce a cozy, yellow light often used in residential settings, while cooler temperatures, around 5000-6500 kelvin, emit a bright, daylight-like glow ideal for workspaces.
