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, including, maintenance and power savings, as well as performance features that are assumed by electronics-savvy consumers such as durability, reliability, longer expected life, and consistent color and settings 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 lights for commercial and residential buildings. With the rising demand for solid-state lighting, LED manufacturers are motivated to develop high-lumen LEDs while LED lighting companies will work hard to integrate the latest technology into retrofit packages and luminaries. animixplay However, new views may be required for individuals to adopt LED technology as an lights source in new installs, or incorporate LED technology in existing light fittings.
Are LEDs suitable for commercial and residential lighting applications?
LEDs are arguably the most energy-efficient light source available. Very good example, LEDs have created well over 80 percent energy savings in the traffic signal industry. However, in this application, the LEDs had two natural advantages:
1. LEDs are monochromatic, so the vast majority of the light generated is used. On the other hand, the white light generated by an incandescent light needs to monitor via a colored filter. Light outside the frequency of the colored lens is wasted.
2. LEDs are directional, so the vast majority of the light generated was emitted towards the lens. On the other hand, light from an incandescent light must be resembled toward the lens, resulting in loss of efficiency.
Commercial and residential lighting applications stand to gain similar, if not more, energy-savings by changing to LEDs. However, most applications are not as straight-forward as filling a PC board with a bunch of directional red, silpada or green LEDs. LED light fittings 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 settings that consumers have become accustomed to with incandescent lights. However, the ability savings can be significant, for example, in California the vitality commission has used efficiency standards for residential and commercial buildings. These standards, Title 24, have accelerated development of LED lights technology.
Why LEDs are not in your house?
Unlike incandescent lamps, high-power LEDs cannot be simply connected to a wall outlet. Several companies will work to overcome the technological and economic challenges by developing LED light fittings and retrofit LED lighting products using high-power LEDs. Arctic management, complex drive circuitry, optics, and packaging are challenging difficulties for developers to handle. There are also educational barriers to overcome in the development of commercial LED lights products. Getting users to take new types of fittings, understand the lights characteristics of LEDs, choose the appropriate viewing angle for a given application, pick the appropriate intensity for a given application, and understand the limitations of LED color temperatures are crucial to developing the market for LED technology in commercial and residential lighting.
Arctic Challenges
For the past couple of centuries, traditional luminaries have contained a lamp and light outlet that allows consumers to continually replace lamps that have burned out. Whether it is an incandescent, compact fluorescent or fluorescent lamp, it will simply prop or drop into an industry-standard outlet and the luminary will continue to be in business. A few LED lighting companies allow us high-flux LED lamps that retrofit into existing sockets; but this method is less than ideal. For example, a normal lamp outlet gives a very poor arctic path for cooling an LED light source. Incandescent lights are basically heating elements that produces visible light, and the outlet it is screwed into is designed to protect the light base and electrical wiring from that heat. With high-power LEDs, most of the wattage consumed is transformed into heat and, if it are not dissipated through the light outlet, will dramatically shorten the LED life.
Complex Drive Circuitry
To protect the LED from destruction factors, such as heat and voltage spikes, the drive circuitry design is very important. Ideally, LED enterprise designs should be tailored to the particulars of the application because mechanical and economic difficulties make it difficult to develop a “catch-all” enterprise. Most LED indication or lighting designs operate from a high voltage AC power source. Since LEDs are DC-driven, having a specific AC to DC power supply to achieve a DC source voltage is often the most cost-efficient and reliable LED lighting solution. To ensure efficient LED operation, DC-to-DC LED driver circuitry may also be required in conjunction with the primary power supply. In addition to providing the required power and protection from current movement, LED drive circuitry also generates heat — increasing the arctic management challenge. And, generally, the greater the actual of light that is required, the more LEDs are essential, leading to more complicated the circuitry, packaging challenges, higher heat flux, etc.
