2. LED circuit - Wikipedia

   en.wikipedia.org/wiki/LED_circuit

   Simple LED (Light Emitting Diode) circuit diagram. 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.

   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 ...

5. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics because of their safety; the hazardous 120 or 240 volt main current is transformed down to a ...

6. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   If an LED lamp does not have free air circulation, the LED is likely to overheat, resulting in reduced life or early failure. The thermal design of the system must allow for the ambient temperature surrounding the lamp; a lamp in a freezer experiences a lower ambient than a lamp in a billboard in a sunny climate.

7. LED strip light - Wikipedia

   en.wikipedia.org/wiki/LED_strip_light

   Less common designs may have 3014, 4014, 7020, 8020, or other SMDs. In addition to the LED SMD type, the quantity of LEDs per meter is also an important factor in determining the overall power and brightness. [5] LED strip lights most commonly operate on 12 or 24 volts of direct current from a power supply, sometimes referred to as a driver ...
