LED – Light Emitting Diode – is a solid-state semiconductor device that converts electrical energy directly into light. There are no moving parts, no gas and no filaments to heat up. A LED semiconductor comprises two regions: one is a positively charged region (P region) and the other is a negatively-charged region (N region).
When a current is passed between these two regions, it causes the electrons to move to the opposite region. It is this movement that creates and releases energy. This energy is called a photon and is visible to the human eye, thus we have a Light Emitting Diode.
LED fixtures have an environmental advantage in that they contain no mercury, last longer and produce less waste, and they are made from fully recyclable materials.
Furthermore, the extruded aluminium heat sink is manufactured using 77% post-industrial recycled material.
A single kilowatt-hour of electricity will generate 610grams of CO2 emissions. Assuming the average light bulb is on for 10 hours a day, a single 100-watt incandescent bulb will generate 222kg of CO2 every year. The 12-watt Switch Lighting LED equivalent will be responsible for only 26kg of CO2 over the same time span.
A building’s carbon footprint from lighting can be reduced by nearly 90% by exchanging all incandescent bulbs for new LEDs.
