2. Chip on board - Wikipedia

   en.wikipedia.org/wiki/Chip_on_board

   The PCB of a quartz watch. The clock IC is under the drop of black epoxy. Chip on board (COB) is a method of circuit board manufacturing in which integrated circuits (e.g. microprocessors) are attached (wired, bonded directly) to a printed circuit board, and covered by a blob of epoxy. [1]

3. List of electronic component packaging types - Wikipedia

   en.wikipedia.org/wiki/List_of_electronic...

   In LEDs, transparent epoxy or a silicon caulk-like material that may contain a phosphor is poured into a mold containing the LED(s) and cured. The mold forms part of the package. COF: Chip-on-flex: Variation of COB, where a chip is mounted directly to a flex circuit. Unlike COB, it may not use wires nor be covered with epoxy, using underfill ...

4. SMD LED - Wikipedia

   en.wikipedia.org/wiki/SMD_LED

   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 dimensions of the LED package. A single multicolor module may ...

5. Light-emitting diode - Wikipedia

   The appearance of objects illuminated by that light may vary as the spectrum varies. This is the issue of color rendition, quite separate from color temperature. An orange or cyan object could appear with the wrong color and much darker as the LED or phosphor does not emit the wavelength it reflects.

6. LED lamp - Wikipedia

   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 ...

8. Solid-state electronics - Wikipedia

   en.wikipedia.org/wiki/Solid-state_electronics

   Other examples of solid state electronic devices are the microprocessor chip, LED lamp, solar cell, charge coupled device (CCD) image sensor used in cameras, and semiconductor laser. Also during the 1960s and 1970s, television set manufacturers switched from vacuum tubes to semiconductors, and advertised sets as "100% solid state" [ 12 ] even ...

9. LED strip light - Wikipedia

   en.wikipedia.org/wiki/LED_strip_light

   An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .
