Why Use LEDs...? Normal lights have served us greatly for generations. But we
must remember that they still rely on an incandescent bulbs and fluorescent
tubes to produce their light. Technology first invented by Thomas Edison and
Nikolai Tesla, way back in the nineteenth century. Technology has taken some
giant leaps forward since that time and now miniature Light Emitting Diodes
(LEDs) are set to become the
standard source of illumination for the 21st Century. What's so great about LEDs? All LEDs today contains solid-state technology similar to those found in microprocessors. These solid-state devices have no moving parts, no fragile glass environments, no mercury, no toxic gasses, and no filament. There is nothing to break, shatter, leak, or contaminate. Unlike typical conventional light sources, LEDs are not subject to sudden failure or burnout. Advantages of using LEDs: - Longer lasting than ordinary lights - over 11 years life span with only 30% degradation (70% lumen maintenance) from initial luminous output. - Reduced Maintenance Costs - Last 10 times longer (over 11yrs life span) than a normal light source, there is no need to replace the light source, reducing ongoing maintenance costs. - Energy efficient - LED uses less energy to produce, there light sources are more efficient than incandescent and most halogen light sources. White Leds today can deliver more than 20 lumens per Watt, and are predicted to achieve greater than 50 lumens per Watt by 2005. - Design Flexibility - LEDs are typically much smaller than conventional light sources, allowing for dramatically different lighting designs capitalizing on the unobtrusiveness of the source. - Vivid Saturated Colours - Light Emitting Diodes require no filters to create coloured light, resulting in deeper saturated colours without wasted light. - Directed Light for Increased System Efficiency - The light emitted from an LED is directional. Typical conventional sources such as incandescent, halogen, or fluorescent lights are omni directional, emitting light in all directions. - Dynamic Colour Control, White-Point Tunable - LEDs can offer intense deep reds, greens, and blues for dynamic colour changing applications. The endless choices of colour are available for almost any application. - Fully Dimmable Without Colour Variation - LEDs are fully dimmable with straightforward driver topologies. For example, Luxeon power light sources can be dimmed by over 1000 times without sacrificing any characteristic of the light. - Instant On, Full Colour, 100% Light - LEDs have turn on times measured in microseconds. The Instant-On feature of LEDs provides additional reaction time in safety critical applications. - No Mercury Lead in the Light Source - Unlike most fluorescent sources, LEDs contains no Mercury Lead. Eliminating Mercury from your lighting system will enable specifiers to meet new and future increasingly stringent environmental regulations. - No Heat or UV in the Light Beam - The leading and most efficient LED products only generate light in the range that a person can see. There are no ultraviolet rays or infrared radiation contained in the light beams of these products, this provides a cool beam with a light source that is safe to touch.
