An LED Light Bulb Or LED Lighting Uses Light-Emitting Diodes To Produce Light

A light source that uses light-emitting diodes to produce light is known as an LED Lighting or light bulb (LEDs). When compared to identical incandescent lamps, LED lamps are much more energy-efficient. They can also be significantly more efficient than the majority of fluorescent lamps. The highest-performing LED lights on the market today have efficiency of 200 lumens per watt (Lm/W). Compared to incandescent bulbs, commercial LED lamps have a lifespan that is many times longer.

To operate from mains power lines, LED lamps require an electronic LED driver circuit, and losses in this circuit mean that the lamp's efficiency is lower than the efficiency of the LED chips it uses. To be compatible with lamp dimmers designed for incandescent lamps, the driver circuit may require special features. Depending on the technology of the luminaires, the current waveform generally contains some distortion.

The increasing demand of LED Lighting Market is being fueled by consumer concern over the environment, the robustness of these lights, government mandates for energy saving, and other factors.

Some LED lights can be used as direct replacements for fluorescent or incandescent lights. Multiple LED packages may be used in LED lights to save costs overall and increase light and heat dissipation. The text on retail LED lamp packaging may include information such as the lumen output, wattage consumption, colour temperature in Kelvin or a colour description such as "warm white," "cool white," or "daylight," the operating temperature range, and occasionally the equivalent wattage of an incandescent lamp delivering the same lumen output.

Prior to the invention of LED Lighting, the majority of general (white) lighting was produced by three different types of lamps. Electric current heats a glowing filament in incandescent lights, which emit light. With a luminous efficacy of 10–17 lumens/W and a brief lifespan of only 1000 hours, these are incredibly inefficient. They are gradually being phased out of uses for general lighting. Since the continuous black body spectrum of light produced by incandescent lamps is similar to that of sunlight, they generate good colour rendering indices (CRI).
