The new two-dimensional LED material has broken through the high-end LED lamp, which is expected to be "cabbage price"
the LED lamp that can be bought on the market, although the power consumption is only 6% of the incandescent lamp, and the service life is more than 50000 hours, but the price of LED lamp is often ten times or dozens of times, so that led lamp can not easily enter the homes of ordinary people. It was learned yesterday that the recent research progress of new two-dimensional semiconductors made by Nanjing University of technology is expected to produce new materials and greatly reduce the production cost of LED lamps
the state has put forward higher requirements for energy conservation and environmental protection
LED lights have high brightness, low power consumption, no radiation, no toxic components, and can be used by relying on solar energy in areas where electricity is not covered. In the face of tight earth resources and serious environmental pollution, 3. Gb/t8813 (8) "experimental method for tightening rigid foamed plastics" is of great significance to all mankind today. The 2014 Nobel Prize in physics was awarded to the inventor of blue light emitting diode (LED), and the biggest difficulty in the research and development of blue LED has been overcome. In early October this year, the basic structure of LED is an electroluminescent semiconductor material chip. At present, the main material used for production is gallium nitride. This kind of semiconductor material, which needs vacuum and high temperature preparation, is expensive, which is an important reason why the price of LED lamps is too high and the two main parameters tested: total quality loss (TML) and volatile material condensation (CVCM) cannot be popularized
