LED Terminology & Information
LED lamps provide the greenest, most eco friendly lighting solution
Light Emitting Diode (LED) is a semi-conductor diode that does not require heating of a filament to create light. Electricity is passed through a semi-conductor material housed in a chip and once it is excited it generates light. LEDs require minimal voltage to illuminate and are shock resistant and shatterproof plus able to operate in extremes of heat and cold, unlike compact florescent lights and halogen light bulbs. LEDs are recyclable unlike compact florescent lights that contain hazardous mercury or gases as in halogen light bulbs.
In August 2008, the worldwide television audience watching the opening and closing ceremonies at the Games of the XXIX Olympiad in Beijing, China, were treated to a series of exceptional LED light shows – greatly increasing the awareness of LEDs. Closer to home, the revolutionary AAMI Park Stadium in Melbourne features a geodesic dome roof that is covered by thousands of LEDs, which are programmed to display a variety of spectacular patterns and images. Since LEDS were first created nearly five decades ago they have become more efficient and cheaper and they are now used in aircraft, automobiles, calculators, clocks, computers, DVD and MP3 players, telephones, televisions plus numerous other electronic devices.
Power Supply to some companies LEDs is via a 240 Volt electrical transformer that converts the output to 12 Volts for these inferior types of LEDs – these transformers need to be purchased, absorb extra energy and due to their large heat sinks fitted generate additional heat and are prone to failure. Due to the design and utilisation of superior technology components in direct 240 Volt LEDs they do not require costly transformers to operate. The latest generation direct 240 Volt LEDs provide brilliant light at a cool 31° Celsius and retain 70% of their intensity for up to 50,000 hours (13 years).
LEDs provide instant bright light from the moment the light switch is turned on, unlike the compact florescent lights that feature a warming period prior to becoming fully operational. In addition, they are not susceptible to failure due to repeated switching on and off plus they do not emit any ultraviolet (UV) radiation that causes damage to curtains and furnishings.
Converting to LEDs can reduce lighting bills by as much as 80% and in some applications by nearly 90%, reducing the demand on energy supplies and the output of CO2 emissions. When purchasing LEDs always ensure that they have undergone full Australian Standards and Electro Magnetic Compliance (EMC) testing (no RF interference) and carry detailed approvals that comply with building and insurance industry standards.
