LED Light Applications: The Wave of the Future

Author£ºAdmin Hit£º507 Time£º2012/6/28 8:38:42

LED or Light Emitting Diodes are on the verge of reaching nearly every sector of modern life. LED lighting was once primarily niche-oriented, but as we march into the 21st Century, this is no longer the case. This is due largely to the use of LED technology in new electronics applications like LCD LED video displays and cell phones as well as newer outdoor applications like street and building lighting. Technology developers see the LED’s energy-efficiency and cost-saving attributes as the wave of the future.

Incandescent electric light is the most widely used light source today, but it has not changed much since its inception almost 100 years ago. Fluorescent light has been around for approximately 30 years. LED lighting is forecasted to replace both incandescent and fluorescent lights in almost every application such as LED flashlights, LED bulbs, and home LED lighting in the next 10-20 years. Since LED lighting has been used for many years in niche applications, the price of manufacturing is steadily dropping and the volume of LED lighting is increasing.
In fact, a recent report by Global Industry Analysts stated that the global market for both fluorescent and LED lighting could reach $97 billion by the year 2010. This increase in growth would be due to LED’s technological superiority over other light sources, energy efficiency, and mobility in such uses as emergency lighting, outdoor lighting and flashlights. The report also revealed that this growth would take place mainly in the construction and industrial development industries.

One reason for growth of LED lighting in the construction industry would be its projected use in residential homes. LED bulbs are wonderful for giving off directional light, such as that needed for reading or for spotlighting works-of-art. Since the light is more directed, less light is wasted. Most LED bulbs can replace many standard fluorescent or halogen light bulbs.

Incorporating LED lighting into an office or residence is, initially, a substantial investment. But the overall savings makes up for it in the long-term. For example, if you purchase 2 60-watt ceiling fan light bulbs at a discount price of $3.00, each bulb costs approximately $1.50 and last 1,000 hours on average. One 2-watt LED light bulb costs around $35 and lasts on average 60,000 hours. You would need to purchase 60 incandescent 60-watt bulbs at $90 to last 60,000 hours. 

Not only do you save on the price per bulb, but you also save on your electricity bill due to LED bulbs energy efficiency. It is estimated that approximately 3,600 kWh of electricity is used for 60,000 hours of incandescent lighting. In contrast, only 120 kWh of electricity is expended for 60,000 hours of LED lighting. At 10 cent per kWh used, your electricity bill would take a beating at $360 for incandescent lighting as opposed to $12 for LED lighting.  These are only rough estimates, and you may find that LED lighting is not suitable for all of your lighting needs. However, by replacing several lights in your home with LED lighting you would not only save money on your electricity bill, but promote energy-efficient living. And that benefits everyone. 

LED lighting and LED lighting displays are leading the way in ultramodern design. For example, LED video is the technology of choice for civic centers and many indoor sporting events. LED video displays are becoming more and more preferred due to their higher brightness. This is crucial for long viewing distances. Advantages of LED video displays are their capability to incorporate curves and 3-D design. This adds an ultramodern touch and eye-catching component to any sign or display.

There are hundreds of applications that are available or are being created that use LED lighting. The U.S. military is using LED applications in UV-LED canteen water treatment devices, sterilization of surgical equipment needed for medical units on the battlefield, and LED flashlights that work in conjunction with night-vision goggles. The automotive industry is moving toward using LED light bulbs in interior lights, taillights, and headlights in many automobiles. The consumer electronics industry is researching LED technology to improve the size, resolution, color and brightness of next generation televisions.

Due to LED lighting’s energy efficiency, high brightness, and technological superiority over other conventional light sources, it is no wonder that researchers and developers are consider this technology for every facet of life in the future.
