design ws2811 LED module to be self-contained to function independently or to be added to a complimentary unit. It is made of parts constructed to produce light from a light emitting diode (LED). Such parts are the LED laden circuit boards, heat, electrical and mechanical interfaces, LED drive and control electronics. LEDs modules are favored for their environment-friendly fixtures. A well-designed LED unit consumes less power while emitting the same amount of light as conventional units.
