23 Facts About LED lightbulb

An LED lightbulb lamp or LED lightbulb light bulb is an electric light that produces light using light-emitting diodes .

LED lightbulb lamps are significantly more energy-efficient than equivalent incandescent lampsand can be significantly more efficient than most fluorescent lamps.

Commercial LED lightbulb lamps have a lifespan many times longer than incandescent lamps.

Some LED lightbulb lamps are drop-in replacements for incandescent or fluorescent lamps.

In 1968, the first commercial LED lamps were introduced: Hewlett-Packard's LED display, which was developed under Howard C Borden and Gerald P Pighini, and Monsanto Company's LED indicator lamp.

However, early LED lightbulb lamps were inefficient and could only display deep red colors, making them unsuitable for general lighting and restricting their usage to numeric displays and indicator lights.

LED lightbulb lamps were used for a number of demonstration projects for outdoor lighting and LED lightbulb street lights.

LED lightbulb lamps are often made with arrays of surface mount LED lightbulb modules that replace incandescent or compact fluorescent lamps, mostly replacing incandescent lamps rated from 0.

Some light from the LED lightbulb is absorbed by the molecules of the phosphor, causing them to fluoresce, emitting light of another color via the Stokes shift.

LED lightbulb drivers are essential components of LED lightbulb lamps to ensure acceptable lifetime and performance of the lamp.

LED lightbulb lamps tend to run cooler than their predecessors since there is no electric arc or tungsten filament, but they can still cause burns.

LED lightbulb lamps are used for both general and special-purpose lighting.

White-light LED lightbulb lamps have longer life expectancy and higher efficiency than most other lighting when used at the proper temperature.

LED lightbulb sources are compact, which gives flexibility in designing lighting fixtures and good control over the distribution of light with small reflectors or lenses.

Unlike other lighting technologies, LED lightbulb emission tends to be directional, which can be either advantageous or disadvantageous, depending on requirements.

LED lightbulb lamps are made with standard lamp connections and shapes, such as an Edison screw base, an MR16 shape with a bi-pin base, or a GU5.

Some models of LED lightbulb lamps are compatible with dimmers as used for incandescent lamps .

LED lightbulb lamps are available with a variety of color properties.

LED lightbulb lamps have decreased substantially in price, and many varieties are sold with subsidized prices from local utilities.

White LED lightbulb lamps have achieved market dominance in applications where high efficiency is important at low power levels.

Colored LED lightbulb lamps are now commercially used for traffic signal lamps, where the ability to emit bright light of the required color is essential, and in strings of holiday lights.

Low power factors can result in surcharges for commercial energy users; CFL and LED lightbulb lamps are available with driver circuits to provide any desired power factor, or site-wide power factor correction can be performed.

LED lightbulb lamps are sensitive to excessive heat, like most solid state electronic components.
