LED street lights are employed on poles and in parking garages. In 2007, the Italian village of Torraca was the first place to convert its street lighting to LEDs. [97] Cabin lighting on recent [when?] Airbus and Boeing jetliners uses LED lighting. LEDs are also being used in airport and heliport lighting.

A LED is a long-lived light source, but certain mechanisms can cause slow loss of efficiency of the device or sudden failure. The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide , and others , with various trace doping elements , are used to produce different ...
The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs (SMD LEDs). [2] Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may ...
A set of modern LED flashlights. A flashlight or electric torch (Commonwealth English), usually shortened to torch, is a portable hand-held electric lamp.Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the early 2000s.
These type of lights were used until reliable batteries and dynamos became available, and manufacturers switched to electric lights. Acetylene lamps were also used on riverboats for night navigation. The National Museum of Australia has a lamp made in about 1910 that was used on board PS Enterprise , a paddle steamer which has been restored to ...
End-users and 3rd-party sellers on eBay often describe connectors by their wrong name thus perpetuating confusion of the exact series of a specific connector. It is very common in blogs and websites to incorrectly name a specific connector only by the name of the manufacturer.
Figure 5: Typical constant current source (CCS) using LED instead of Zener diode. The Zener diode can be replaced by any other diode; e.g., a light-emitting diode LED1 as shown in Figure 5. The LED voltage drop (V D) is now used to derive the constant voltage and also has the additional advantage of tracking (compensating) V BE changes due to ...
