Are LEDs suitable for commercial and residential lighting applications?

LEDs are arguably the most energy-efficient light source available. Case in point, LEDs have created upwards of 80 percent energy savings in the traffic signal industry. However, in this application, the LEDs had two natural advantages:

1. LEDs  fasadskylt  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.

2. LEDs 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 LEDs. However, most applications are not as straight-forward as stuffing a PC board with a bunch of directional red, amber or green LEDs. 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 fasadskylt   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.

Why LEDs are not in your house?

Unlike incandescent bulbs, high-power LEDs cannot be simply plugged into a wall socket. Several companies are working to overcome the technological and economic challenges by developing LED light fixtures and retrofit LED lighting products using high-power LEDs. fasadskylt   Thermal management, complex drive circuitry, optics, and packaging are challenging hurdles for developers to contend with. There are also educational barriers to overcome in the development of commercial LED illumination products. Getting users to adopt new types of fixtures, understand the illumination characteristics of LEDs, choose the appropriate viewing angle for a given application, select the appropriate intensity for a given application, and understand the limitations of LED fasadskylt   color temperatures are pivotal to developing the market for LED technology in commercial and residential lighting.
