A light emitting diode (LED) is a device that produces light due to the movement of electrons when an electric current is passed through a semiconductor material. A diode is a simple device which uses one piece of material with excess electrons (N-type material) connected to another piece of material with excess holes (P-type material). The two materials meet in an area referred to as the PN junction. When an electrical current is passed through the diode, light is produced at the PN junction as electrons move from a high energy level into a lower energy one and give off the excess energy as light.
Benefits of LED lighting
Owing to the numerous benefits that come with using LED lighting, more home and business owners are upgrading to LED illumination.
LED lights are up to 80 percent more efficient than traditional lighting such as incandescent and fluorescent lamps. They convert 95 percent of the energy produced into light, and only 5 percent is wasted as heat. This is compared to fluorescent bulbs which convert only 5 percent of energy to light and 95 percent into heat. LED lights also draw much less power as compared to traditional lighting to give the same level of light. Better energy efficiency translates to decreased greenhouse gas emissions and reduced demand from power plants.
Longer life span
LED lights and diodes have outstanding operational lifetime expectations. Some LED lights will work for more than ten years of continuous operation.
LEDs are built with sturdy components that make them extremely durable. Their resistance to external impacts, shock and vibration make them ideal for outdoor lighting systems, rough conditions and exposure to the vagaries of weather. They are also ideal for operation under cold and low-temperature settings such as freezer rooms and winter settings.
Flexibility in Design
LEDs can be combined to form different shapes for highly efficient lighting. They can also be dimmed allowing for dynamic control of light, distribution and color. A well-designed LED lighting system can be used to set the right mood and also achieve fantastic lighting effects. That explains the growing popularity of LED lights in classrooms, airplanes and many more locations.
Frequent switching and instant lighting
LED lights brighten up immediately upon being powered on, which makes them ideal for infrastructure projects such as signal and traffic lights. Also, they can be turned on and off frequently without affecting the LED’s light emission or operational life expectancy.
LED lights are free of toxic chemicals and are 100 percent recyclable. Most conventional lighting solutions such as fluorescent bulbs will contain toxic materials like mercury, which are harmful to the environment.
Close to no UV emissions
LED light produces close to no UV emissions and little infrared light. That makes LED lighting suitable not only for illumination of UV sensitive materials and objects but also for lighting heat-sensitive goods and materials.
LEDs represent a revolution in the future of lighting. Their widespread use has a tremendous potential impact on energy savings for both home and business owners.
Thanks to the Retailer Energy Efficiency Scheme (REES), South Australian businesses may be able to access free or subsidised energy efficiency activities from energy retailers participating in the scheme. Low-income households also stand to benefit from energy audits. The main idea is to provide incentives for businesses in South Australia to save energy through establishing energy efficiency and audit targets to be met by electricity and gas retailers.
The recommended REES energy efficiency activities are set by the Ministry for Mineral Resources and Energy, but each energy vendor in the scheme decides the mix of efficiency activities it will take on to meet its targets. Contact us today to find out how your Adelaide Business can take advantage of the REES scheme.
