The computer industry is well suited to manufacture LED lighting. The process isn't a whole lot different than making a computer motherboard. The companies making the LEDs themselves are generally not in the lighting business, or it is a minor part of their business. They tend to be semiconductor houses that are happy cranking out their product, which is why prices on high-output LEDs has fallen so much in the last 15 years.

LED bulbs themselves are expensive in part because daisys it takes a number of LEDs to get wide-area illumination instead of a narrow beam, and the assembly cost adds to the overall price. In addition, assemblies consisting of arrays of LEDs create more opportunities for product defects.

An LED light consists of four essential components: an LED circuit board, a heatsink, a power supply, and a shell. The lights start out as bare printed circuit boards (PCcool smiley and high luminance LED elements arrive from separate factories which specialize in making those components. LED elements themselves create a bit of heat, so the PCB used in lighting fixtures is special. Instead of the standard non-conductive sandwich of epoxy and fiberglass, the circuit board is laid out on a thin sheet of aluminum which acts as a heatsink.
