22 Facts About LED lighting
2.
LED lighting lamps are significantly more energy-efficient than equivalent incandescent lampsand can be significantly more efficient than most fluorescent lamps.
| FactSnippet No. 978,580 |
3.
Commercial LED lighting lamps have a lifespan many times longer than incandescent lamps.
| FactSnippet No. 978,581 |
4.
Some LED lighting lamps are drop-in replacements for incandescent or fluorescent lamps.
| FactSnippet No. 978,582 |
5.
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.

6.
However, early LED 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.

7.
LED lighting lamps are often made with arrays of surface mount LED lighting modules that replace incandescent or compact fluorescent lamps, mostly replacing incandescent lamps rated from 0.
| FactSnippet No. 978,585 |
8.
General-purpose LED lighting requires a white light, emulating a black body at a specified temperature, from "warm white" at 2700K, to "daylight" at around 6000K.

9.
Some light from the LED lighting is absorbed by the molecules of the phosphor, causing them to fluoresce, emitting light of another color via the Stokes shift.
| FactSnippet No. 978,587 |
10.
LED lighting drivers are essential components of LED lighting lamps to ensure acceptable lifetime and performance of the lamp.
| FactSnippet No. 978,588 |
11.
LED lighting lamps tend to run cooler than their predecessors since there is no electric arc or tungsten filament, but they can still cause burns.
| FactSnippet No. 978,589 |
12.
White-light LED lamps have longer life expectancy and higher efficiency than most other lighting when used at the proper temperature.
| FactSnippet No. 978,590 |
13.
Unlike other lighting technologies, LED emission tends to be directional, which can be either advantageous or disadvantageous, depending on requirements.
| FactSnippet No. 978,591 |
14.
LED lighting 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.
| FactSnippet No. 978,592 |
15.
Some models of LED lamps are compatible with dimmers as used for incandescent lamps .
| FactSnippet No. 978,593 |
16.
LED lighting lamps are available with a variety of color properties.
| FactSnippet No. 978,594 |
17.
LED lighting lamps have decreased substantially in price, and many varieties are sold with subsidized prices from local utilities.
| FactSnippet No. 978,595 |
18.
Light emitting diodes offer efficient electric lighting in desired wavelengths which support greenhouse production in minimum time and with high quality and quantity.
| FactSnippet No. 978,596 |
19.
White LED lighting lamps have achieved market dominance in applications where high efficiency is important at low power levels.
| FactSnippet No. 978,597 |
20.
Colored LED lighting 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.
| FactSnippet No. 978,598 |
21.
Low power factors can result in surcharges for commercial energy users; CFL and LED lighting lamps are available with driver circuits to provide any desired power factor, or site-wide power factor correction can be performed.
| FactSnippet No. 978,599 |
22.
LED lighting lamps are sensitive to excessive heat, like most solid state electronic components.
