SMD LED

The light from white LED lamps is usually provided by industry standard LED surface-mounted devices (SMD's). Non-SMD types of LED lighting also exist, such COB (chip on board) and MCOB (multi-COB).
SMD LED Modules are described by the dimensions of the LED package. A single multicolor module may have 3 individual LEDs within that package, one each of red, green and blue, to allow many colors or shades of white to be selected, by varying the brightness of the individual LEDs. LED brightness may be increased by using a higher driving current, at the cost of reducing the device's lifespan.
