staff writer LEDCanada Positive benefits of installing LED lighting North America Has begun to wean its citizens of one of the oldest inventions still in use today, the common incandescent lightbulb, unfortunately a large percentage of the population have become disenchanted with compact fluorescent lights (CFL). Which up until recently has been the only alternative available commercially. Enter next-generation LEDs, using super (HBLED) chips from companies such as Cree, manufacturers around the world have the opportunity to incorporate LED light engines into new exciting products.
Top marks in every category
- much lower operating temperatures
- no hazardous UV output
- contain no toxic mercury or lead
- offer complete color range, 3000 to 10,000 Kelvin(orange to blue)
- have no moving parts and are much more robust and resistant to vibration than other light bulbs available on the market.
- have a much longer life span than regular bulbs. Some LEDs can operate for up to 100 000 hours, depending on the quality of the diode and the application. (The life span for LEDs can vary significantly and light output will diminish over time.)
- produce a highly visible light and are compact in size, facilitating their use in a variety of capacities.
- produce coloured light, eliminating the need for a tinted lens to produce the desired colour. In outdoors applications, this prevents a phenomenon known as "phantom light," which occurs when the sun (or other light) reflects off a tinted lens or traditional light source and makes a light appear to be on when it is off.
- do not generally suffer catastrophic failure after initial energizing. If individual diodes do fail, the overall light output will not be noticeably affected, thus strengthening product reliability. This feature, along with LEDs' resistance to impact and vibration, can make a lighting product less prone to vandalism in some applications.
- can deliver additional savings through reduced maintenance costs (i.e., they can avoid the material and labour costs involved with continually replacing conventional bulbs).
