Led Panel Light are arguably the most energy-efficient light source available. Case in point, Led panel light have created upwards of 80 percent energy savings in the traffic signal industry. However, in this application, the Led panel light had two natural advantages:
Led panel light are monochromatic, so almost all of the light generated is used. In contrast, the white light generated by an incandescent bulb needs to transmit through a colored filter. Light outside of the frequency of the colored lens is wasted.
Led panel light are directional, so almost all of the light generated was emitted towards the lens. In contrast, light from an incandescent bulb needed to be reflected toward the lens, resulting in loss of efficiency.
Commercial and residential lighting applications stand to gain similar, if not more, energy-savings by converting to Led panel light. However, most applications are not as straight-forward as stuffing a PC board with a bunch of directional red, amber or green Led panel light. LED light fixtures and retrofit packages have to be designed to distribute the directional light generated by the LED over wide areas.
Moreover, white LED technology ，while continuously improving, does not yet have the optical color and brightness that consumers have become accustomed to with incandescent lights. However, the power savings can be significant, for example, in California the energy commission has adopted efficiency standards for residential and commercial buildings. These standards, Title 24, have accelerated development of LED illumination technology.
