subject: Led Light As The Major Light Source For Next Generation [print this page] Light Emitting Diode or LED light has been in existence for many years, basically in niche applications such as small trinkets and indicator lighting. However, owing to LED light being highly energy saving, not to mention technologically superior over other light sources like incandescent and fluorescent lighting, it is expected to reach beyond electronic uses into commercial and home lighting as well. In a recent report by Global Industry Analysts it is predicted that the market for fluorescent and LED light could go up to $97 billion by 2010. The increase in growth would be mainly from construction and industrial development sectors.
As more people become aware of the energy efficiency of LEDs, the cost of such items as LED bulbs will decline in price. Currently, the price of one LED bulb is substantially higher than the price of incandescent or fluorescent lighting. However, the initial price for the lights would more than pay for itself in the long run. On average, one incandescent 60-watt bulb endures 1,000 hours whereas one 2-watt LED light bulb endures 60,000 hours. Therefore, one would need to purchase 60 incandescent bulbs for each LED light bulb.
Home LED light is a cut above the rest when it comes to energy efficiency. As compared to incandescent lighting, LEDs wins hands down where energy consumption is involved. For every 60,000 hours of usage, incandescent lighting uses approximately 3,600 kWh of electricity where LED lights use 120 kWh. Bottom line: energy efficiency equals a valuable cost savings. LEDs gives off directional illumination. Therefore, it is useful as a source of light for reading or spotlighting in the home. Its powerful light productivity also makes it wonderful for outdoor floodlighting and path illumination. These bulbs are now available that can replace most halogen or fluorescent light bulbs used in the home.
Although LED light may not be suitable for all home lighting needs, changing a few bulbs would have a noticeable affect in the amount of electricity used.
LEDs are already utilized in signs and videos in many indoor and outdoor sporting events and concerts. LED video displays and signs are often preferred because of their improved brightness, which is critical when people are watching a sign or video from a long distance. Added advantages of these video displays are their ability to incorporate curves and 3-D design. This makes LED displays technologically superior to currently available large screen shows. Research and manufacturers in the consumer electronics space are eager to take advantage of this extremely useful technology in future items.
Other uses for LED light include flashlights and key chains, car taillights and interior lights, and LED-based projection TVs. LED light is also being used in the army for LED flashlights that is used in night-vision goggles, UV-LED canteen water treatment devices and the sterilization of surgical instruments.
With LED light being more energy saving and technologically superior to other light sources, numerous applications are sure to evolve. Future generations can expect to think LED light as the standard light source for most lighting applications.
