2. LED strip light - Wikipedia

   en.wikipedia.org/wiki/LED_strip_light

   An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .

3. SMD LED - Wikipedia

   en.wikipedia.org/wiki/SMD_LED

   Contents. (Top) SMD LED. The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs (SMD LEDs). [ 1 ] 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.

4. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   Main article: Light-emitting diode physics. In a light-emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called "electroluminescence". The wavelength of the light depends on the energy band gapof the semiconductors used.

5. LED lamp - Wikipedia

   en.wikipedia.org/wiki/LED_lamp

   Contents. LED lamp. A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An LED lamp or LED light[ 1 ] is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and fluorescent lamps ...

6. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   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 ...

7. Rework (electronics) - Wikipedia

   en.wikipedia.org/wiki/Rework_(electronics)

   Rework (electronics) In electronics, rework (or re-work) is the repair or refinish of a printed circuit board (PCB) assembly, usually involving desoldering and re- soldering of surface-mounted electronic components (SMD). Mass processing techniques are not applicable to single device repair or replacement, and specialized manual techniques by ...
