Why LED Lighting Is Not In Your Home Yet

Conventional LEDs have been used for indication and display applications for several decades. The inherent benefits of LED technology are well-known and documented, and include, maintenance and power savings, as well as performance features that are taken for granted by electronics-savvy consumers such as durability, reliability, longer life span, and consistent color and brightness levels. These benefits, combined with society’s growing environmental concerns and subsequent demand for green, energy-efficient products, have continued to drive the development of LEDs for challenging new industries and markets, such as general illumination for commercial and residential buildings. With the escalating demand for solid-state lighting, LED manufacturers are motivated to develop high-lumen LEDs while LED lighting companies are working hard to integrate the latest technology into retrofit packages and luminaries. However, new perspectives may be necessary for people to adopt LED technology as an illumination source in new installations, or incorporate LED technology in existing light fixtures.

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 Stand for Computer Monitor, Cable Management System B07DND2W6W:

1. LEDs 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 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.
