U.S. Pacific Light Technologies (PLT)’s researchers are researching LED coating materials, the results of the user may save billions of dollars for the LED lighting costs.
The study will likely increase by 50% LED luminous efficiency, while allowing the LED to emit the different light that is difference with the usual pale shades and warmer. The coating products will further eradicate the problem of toxic heavy metals, and further reduce production costs. With the help of equipment and manpower of the Oregon State University， PLT company adjust production processes of the coating. Coating contains the micro semiconductor composiing the quantum dots, enabling more efficient blue LED light.
Juanita Keer Ting who is one of the co-founder and chief technology officer of the PLT said: “This project aims to promote non-toxic lighting at reasonable prices, which will bring great energy-saving effects ，if using the LED that is of the reasonable proportion to light, then the total lighting energy consumption will likely be reduced by 50 percent by 2030. ”
US Oregon promote non-toxic coating material LED research projects
Greg Herman who is the chemical engineering professor of the Oregon State University and the researcher of the Oregon Built Environment and Sustainable Technology is the project leaders, the research is conducted at Oregon solar cell production process innovation centers of the Oregon State University. At a news conference, Professor Herman said: “We believe we are able to precisely control the size of quantum dots in the 5-10 nm, thereby controlling the light color emitted by the LED. This project is very suitable for our experiments chamber, and is also my interest, because it focus on the use of non-toxic materials and improving energy efficiency. If we can do all use LED lighting, the savings will be a huge amount of energy. ”
Since the LED that is the light-emitting diode was invented in 1962，LED has been improved and innovated，especially which has been applied as lighting with the forms of the LED lighting，the LED semiconductor lighting as the third generation of lighting because of energy saving and environmental protection has highly praised and largely used in our daily life.
Meanwhile，the LED flood lights and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life，the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood lights is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile，there a large number of factory engaging in developing and producing the LED light，Lead Lighting is just one of them，which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood lights so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood lights, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection.
