   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 ...

   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. Carrier generation and recombination - Wikipedia

   en.wikipedia.org/wiki/Carrier_generation_and...

   Carrier generationdescribes processes by which electrons gain energy and move from the valence band to the conduction band, producing two mobile carriers; while recombinationdescribes processes by which a conduction band electron loses energy and re-occupies the energy state of an electron hole in the valence band.

5. 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.

7. 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’.
