Yesterday, there was a magical “surface light source†at Nanjing University of Technology. Compared with the common LED “point light source†on the market, it not only saves 20% of electricity, but also has ten times the same wattage, and the average life can be Up to 30,000 to 50,000 hours.
Yan Guohua, general manager of Nanjing Xiongyan Optoelectronics Technology Co., Ltd. in the National University Science and Technology Pioneer Park of Nanjing University of Technology, said, “The light source is actually a luminous body.†Yan Guohua pointed to a circular sheet at the lamp head, saying that this small wafer is like a mini. CD, less than 4 cm in diameter, less than 1 mm thick, with a yellow background. Look closely, there are small black spots on it. “Actually, every little black dot is a tiny illuminator.â€
This technology was jointly developed by Lu Hanxiong, a member of the Hong Kong Institution of Engineers, and Nanjing University of Technology. Both the light source chip and the driver chip have their own intellectual property rights. It is understood that the Asian Youth Club will be held in Nanjing next year, and the athletes' dormitory in Pukou District is also expected to use the "surface light" lamp.
Convection Heater
The heater on the shell for the outlet, the bottom of the air intake, power after the electric tube around the air is heated to rise from the outlet outflow, and the surrounding cold air from the inlet into the supplement. So repeated cycle, so that the indoor temperature can be improved. When the inlet and outlet are blocked or the ambient temperature is too high, the temperature control element will automatically cut off the electric tube power supply. This heater is used in the power of about 800 watts, but also by increasing the number of electric tube connected to adjust the power. The safety of the heater is high, running quiet, the disadvantage is to slow down the temperature.
