Looking back at the lighting industry, with the development of science and technology, lighting sources have developed from incandescent lamps, fluorescent lamps, and HIDs to the fourth-generation green new energy LEDs. Not only have the principle of illumination changed, but the lighting sources have become more energy-efficient, environmentally friendly, and green. Under the global energy crisis, the domestic phase-out of incandescent lamps was put on the agenda in October 2012. At the same time, mercury pollution from energy-saving lamps has attracted the attention of the general public. In this case, the promotion of LED lighting applications is valued by the state, government, and enterprises. However, the current wide application of LED lighting is also hindered by technical issues such as heat dissipation design, materials, electrical accessories, and drive power. Xiaobian specially counts new technical articles in the LED lighting industry for nearly a week.
The world's first: 36-volt lighting product Heyuan was born
After years of research, a world-first, safer, more energy-efficient and environmentally-friendly lighting product, the "36-volt LED lighting system" has been successfully developed and mass-produced in Heyuan. The inventor is the teacher of Yuanshan Town Central Primary School in Lianping County. A research team led by Liu Dongxing. It is reported that the "36 volt LED lighting system" consists of two parts: "AC 220 volts to DC 36 volts" safety and energy saving switch and 36 volt LED lighting. A great advantage of this invention is that the user does not have an electric shock hazard. The key to not causing an electric shock hazard is on the safety switch. For this invention alone, 18 national patents and utility model patents have been applied.
The University of Toronto has developed a thermal solution for controlling LED lights
LED lamps have the characteristics of energy saving and longevity, but their brightness is far less than the brightness emitted by 100-watt incandescent lamps, and as the brightness increases, the problem of LED lamps heating up and losing life will also appear. However, recently, three alumni of the University of Toronto have jointly developed a feasible solution that can improve the brightness of LED lights and effectively control the heat generated by LED lights.
The solution is actually a specially designed electric light called NanoLight, which looks like a classic 100W light bulb. Its surface is covered with a conductive circuit board, and a certain number of LED lights are evenly distributed, so that it can provide illumination in a wide range. And increase the brightness.
American scientists have developed new materials for warm white LED lights
It is well known that LED (Light Emitting Diode) lamps are energy efficient and have a long life, but since the current LED lamps are mainly light blue cold light, this hinders its popularity in the field of indoor lighting. Today, scientists at the University of Georgia in the United States have developed what is said to be the world's first warm white LED lamp that uses a single phosphor and a single illumination unit. A paper on the details of this material was published in the latest issue of the journal Nature Science and Applications of Nature Publishing Group.
