When the power is turned on, it is not a common filament that causes the bulb to emit bright light, nor is it an LED light-emitting diode, but a brand-new "lighting chip." This kind of new lighting tool called Qianzi LED Small Sun Lighting has passed the national patent examination and announced it. The invention was actually spent two years by Wang Ningjun, an ordinary retired cadre of Changsha City Industrial and Commercial System. Developed in 10,000 experiments.
LED city lighting is the mainstream lighting method adopted by China in public places such as urban lighting, parks and streets. However, these lamps mainly use low-power LED modules. These modules are composed of many LED light-emitting tubes like small bulbs. The common problem of such lamps is high cost and unsatisfactory heat dissipation. After a period of use, the brightness will decrease significantly due to the temperature rise, and the life will be greatly shortened. Wang Ningjun and several professors from Central South University and Changsha University of Science and Technology, after a long period of exploration, finally invented what he called "lighting chip" components, and solved the world problem of LED lamp cooling bottleneck. This kind of lamp is illuminated by a chip, and almost no heat is felt when used. Wang Ningjun said: "His principle is completely different from ordinary light bulbs. It is an electronic impact light with high efficiency." This lamp has a lifespan of 10-20 times that of traditional lamps, up to 100,000 hours, and power consumption is less than 20% of traditional lamps. Experts believe that the promotion of this technology will bring about a revolution in the way life lighting.
