The Australian Capital Territory has Replaced Old Downlights with LEDs
LED (which means Light-Emitting-Diode in Chinese) is a semiconductor that can convert electrical energy into visible light. It changes the principle of tungsten filament luminescence for incandescent lights and tri-color powder luminescence for energy-saving lights, using electroluminescence. It is a commonly-used energy-saving light nowadays.
Compared with traditional bulbs, the advantages of LED lights are: no delay in lighting, faster response time (while traditional glass bulbs have a delay of 0.3 seconds to prevent rear-end collision); LED lights have greater aseismatic performance; high luminous purity; low luminous heat, not very high requirements for heat resistance of light materials; power consumption is only 6% of traditional bulbs; ultra-long life, no filament structure and no heat, normal use for more than 6 years; vehicle control circuit is not easy to be oxidized, etc. LED lights have been put into use in large quantities.
According to the Australian News Network, as part of improving urban infrastructure, about 30% of street lights in the Australian Capital Territory (ACT) have replaced old downlights with LEDs. In addition, approximately 1 million square meters of pavement in 21 districts will be renovated or resurfaced this fiscal year.
According to information published on the official website of the ACT government, Chris Steel, the minister in charge of roads and transportation, announced that: "The ACT government is committed to providing residents with better urban facilities. These two projects are just part of it."
According to Steel, replacing old downlights with LEDs has saved 32% of power consumption, which is an increase of 3% over the estimated energy-saving ratio. In addition to energy saving, LED energy-saving lights can provide better illumination for roads. It is estimated that the use of LED street lights will eventually save 20 million kWh of electricity each year.
This fiscal year, the ACT government will improve the road surface of 230 kilometers. The road area is about 1 million square meters.
Steel stated that repairing cracks and defects on the road can ensure the safety of the residents of the capital and improve the efficiency of traffic.
