LED is short for light-emitting diode. It was first used in 1968. Leds are semiconductors that emit light through electricity. At present, LED lighting has been widely used in all kinds of lighting, and gradually replaced the traditional white bulb. Although LED lights and traditional lamps than many environmental protection, but LED recycling is very important.
LED performance and application
Leds have replaced traditional white bulbs for several reasons.
First, leds generally last longer than traditional white bulbs, with an average life of 1,200 hours, compared with 50,000 hours for leds.
Second, LED bulbs use less electricity and have better lighting. This makes leds a cost-effective and environmentally friendly technology. Moreover, LED bulbs do not contain mercury, as CFL bulbs do. Leds are also very durable and can withstand more wear and tear than conventional bulbs. LED lighting is not affected by climate. Neither humidity nor low temperature will affect the operation of LED lighting. LED bulbs emit 10 percent less carbon dioxide than conventional bulbs.
LED applications cover a wider range of products, including:
TV screens, laboratory equipment, cell phones, watches, computers, home lighting, retail lighting, traffic signs and brake lights for cars. These are some of the applications of LED, LED continues to replace tungsten lamp, there will be more LED lights used in daily life.
LED the recovery
LEDS have always been green throughout their life cycle, but if they can be recycled, they will be even greener. More than 95 percent of leds are recyclable, and waste recycling companies buy used LED lighting at low prices.
When leds do not contain any harmful substances, they are classified as RoHS compliant. RoHS was adopted in the UK in January 2006 to restrict the use of hazardous substances in electrical and electronic equipment. This restriction prevents the sale of products containing mercury, lead, cadmium, pbdes, pbdes and hexavalent chromium. Because of this standard, leds can be treated and recycled just like regular bulbs.
The general process of recycling is to break and separate LED bulbs, using a strip screen to form the component. In this step, the glass passes through a magnetic field that can move any nonferrous metal substance. To remove the LED’s aluminum and lead, nonferrous metal separators blast through the shattered glass, guiding the metal to a separate metal groove. The rest of the glass, like aluminum, can be made into other products. Glass is not degraded by recycling, so it can be reused all the time.
In the UK, LED lighting is governed by the WEEE standard, which determines when LED products should be phased out. WEEE stands for waste electrical and electronic equipment (WEEE), which is a collection standard established to encourage recycling. The epa recently changed the rules for WEEE so that all LED companies, such as Recolight, must comply. Under the new requirement, people are required to check whether lighting producers are handling the cost of recovery under WEEE9.2.
The environmental benefits of recycling leds
Although leds themselves are environmentally friendly, if recycled correctly, they have even less impact on the environment. A recent study by the university of California found that most leds contain a high proportion of nickel, while colored leds contain a high amount of lead. In addition, arsenic levels are above the legal limit.
These substances are not only harmful to the environment, but also affect human health. Although leds are more environmentally friendly than traditional bulbs, they are not as disposable as white bulbs, and the impact of leds may be long-lasting.
LEDS also contain a large amount of aluminum, and the greater impact may be due to the energy and resources used to make them. Given the huge demand for LED lights in recent years, recycling leds is more important than extending the life of leds, making them sustainable in the future.
