2. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   The mechanism causing efficiency droop was identified in 2007 as Auger recombination. [14] [15] In addition to being less efficient, operating LEDs at higher electric currents creates more heat, which can compromise LED lifetime. High-brightness LEDs often operate at 350 mA, which is a compromise between light output, efficiency, and longevity ...

3. LED lamp - Wikipedia

   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 ...

4. Light-emitting diode - Wikipedia

   Efficiency: LEDs emit more lumens per watt than incandescent light bulbs. [164] The efficiency of LED lighting fixtures is not affected by shape and size, unlike fluorescent light bulbs or tubes. Size: LEDs can be very small (smaller than 2 mm 2 [165]) and are easily attached to printed circuit boards.

5. Carrier generation and recombination - Wikipedia

   The mechanism causing LED efficiency droop was identified in 2007 as Auger recombination, which met with a mixed reaction. [15] In 2013, an experimental study claimed to have identified Auger recombination as the cause of efficiency droop. [16]

6. LED tube - Wikipedia

   en.wikipedia.org/wiki/LED_tube

   LED tube. LED tube is a type of LED lamp used in fluorescent tube luminaires with G5 and G13 bases to replace traditional fluorescent tubes. [1] As compared to fluorescent tubes, the most important advantages of LED tubes are energy efficiency and long service life. LED tubes are sometimes also referred to as ‘LED fluorescent tubes’.

7. LED circuit - Wikipedia

   en.wikipedia.org/wiki/LED_circuit

   In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. The voltage drop across a lit LED is approximately constant over a wide range of ...
