2. SMD LED - Wikipedia

   en.wikipedia.org/wiki/SMD_LED

   Comparison of SMD LED modules used on an LED strip light [1] The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs (SMD LEDs). [2] 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 ...

3. LED circuit - Wikipedia

   en.wikipedia.org/wiki/LED_circuit

   In CC drivers, the voltage changes while the current stays the same. CC drivers are used when the electrical load of the LED circuit is either unknown or fluctuates, for example, a lighting circuit where a variable number of LED lamp fixtures may be installed. As an LED heats up, its voltage drop decreases (band gap decrease [1]). This can ...

4. 3-way lamp - Wikipedia

   en.wikipedia.org/wiki/3-way_lamp

   A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were built as early as 1902 to allow adjustable lighting levels. [1] Certain compact fluorescent lamp bulbs are designed to replace 3-way incandescent bulbs ...

   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

   One HP-LED can often replace an incandescent bulb in a flashlight, or be set in an array to form a powerful LED lamp. Some HP-LEDs in this category are the Nichia 19 series, Lumileds Rebel Led, Osram Opto Semiconductors Golden Dragon, and Cree X-lamp.

7. Electric light - Wikipedia

   en.wikipedia.org/wiki/Electric_light

   An electric light, lamp, or light bulb is an electrical component that produces light.It is the most common form of artificial lighting.Lamps usually have a base made of ceramic, metal, glass, or plastic which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well.
