2. Thermal management of high-power LEDs - Wikipedia

   en.wikipedia.org/wiki/Thermal_management_of_high...

   LED power dissipation is modeled as a current source; thermal resistance is modeled as a resistor; and the ambient temperature is modeled as a voltage source. High power light-emitting diodes (LEDs) can use 350 milliwatts or more in a single LED. Most of the electricity in an LED becomes heat rather than light – about 70% heat and 30% light. [1]

3. LED circuit - Wikipedia

   en.wikipedia.org/wiki/LED_circuit

   Many circuits operate LEDs at less than the specified maximum current to save power, or to reduce brightness, or to use a common resistor value. For indoor use, tiny surface mount high-efficiency LEDs can easily light up with 1 mA (0.001 A) or more current, which most digital logic outputs can easily source or sink.

4. Wedge base - Wikipedia

   en.wikipedia.org/wiki/Wedge_base

   A small resistor may also be contained in the base of older two-volt LED colors (red, orange, yellow) when in a mixed-color set, so that they match the three volts needed by the newer colors (blue, deep green, purple, white), however other manufacturers only change the value of the resistor that is a part of the cord set itself.

   A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...

6. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   Efficiency: LEDs emit more lumens per watt than incandescent light bulbs. [65] 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 [66]) and are easily attached to printed circuit boards.
