LED is an abbreviation for light-emitting diode. LED lighting devices produce up to 90% more light than incandescent light bulbs.

How do they function?

An electrical current flows through a microchip, illuminating the small light sources known as LEDs, resulting in visible light. The heat produced by LEDs is collected into a heat sink to prevent performance difficulties.

LED Lighting Product Lifespan

LED lighting products have a different useful life than other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs do not often “burn out” or fail. Instead, they suffer from 'lumen depreciation,' in which the brightness of the LED gradually fades over time.

LEDs are used in bulbs and fixtures used in general lighting applications. LEDs, despite their small size, offer unique design choices. Some LED bulb solutions may physically resemble known light bulbs and have a more traditional appearance. LEDs may be incorporated into some LED light fixtures as a permanent light source. There are also hybrid ways that use a non-traditional "bulb" or changeable light source format that is expressly built for a specific fixture. LEDs provide a greater scope for creativity in lighting form factors and apply to a broader range of applications than previous lighting technologies.

Heat sinks are used in LEDs to absorb the heat produced by the LED and distribute it into the surrounding environment. LEDs are kept from overheating and burning out as a result of this. Thermal management is often regarded as the single most essential component in an LED's long-term performance. The higher the temperature at which the LEDs are used, the faster the light degrades and the shorter the useful life.

To manage heat, LED products employ a range of distinct heat sink designs and layouts. Today, material improvements have enabled manufacturers to create LED bulbs that mimic the forms and sizes of typical incandescent lamps.

Difference

LEDs are “directional” light sources, meaning they emit light in only one direction, as opposed to incandescent and CFL bulbs, which release light and heat in all directions. This means that LEDs can use light and energy more efficiently in a wide range of applications. It does, however, imply that advanced engineering is required to create an LED light bulb that shines light in all directions.
