2. 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 ...

3. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   Very small (1.6×1.6×0.35 mm) red, green, and blue surface mount miniature LED package with gold wire bonding details. These are mostly single-die LEDs used as indicators, and they come in various sizes from 1.8 mm to 10 mm, through-hole and surface mount packages. [47] Typical current ratings range from around 1 mA to above 20 mA.

4. Surface-mount technology - Wikipedia

   en.wikipedia.org/wiki/Surface-mount_technology

   Surface-mount capacitor A MOSFET, placed upon a British postage stamp for size comparison. Surface-mount technology (SMT), originally called planar mounting, [1] is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). [2]

5. LED lamp - Wikipedia

   en.wikipedia.org/wiki/LED_lamp

   LED lamps are often made with arrays of surface mount LED modules. A significant difference from other light sources is that the light is more directional. An LED is a "Lambertian" emitter, producing a cone of light with half-power points about 60° from the axis. A laser diode is another form of LED emitter, but produces light by a different ...

   Chip-size package (CSP) developed by National Semiconductor [21] COB: Chip on board: Bare die supplied without a package. It is mounted directly to the PCB using bonding wires and covered with a blob of black Epoxy. [22] Also used for LEDs. In LEDs, transparent epoxy or a silicon caulk-like material that may contain a phosphor is poured into a ...
