Innovation often means substitution. New technologies and products replace outdated technologies and products. So incandescent lamps replace kerosene lamps, energy-saving lamps replace incandescent lamps, and LED lamps will replace halogen lamps, fluorescent lamps and incandescent lamps. Today, when the LED market is rising, how should the application innovation of LED be reflected? The answer is design. Will the new design also replace the outdated design? Maybe it is true for clothes. But for LED designers, the distinction between the past and the future does not need to be so clear. At this point, Yoki Junping can be a model. Yoki Junping is GB (GAMEBOY) And the father of the WS handheld game console, is the initial backbone member of the Japanese game and host manufacturer Nintendo Co. , Ltd. , and the director of the Nintendo Development Department. He developed and designed GameWatch, red and white machine, GameBoy, VIRTUABOY and other game products, which were popular and made great contributions to Nintendo's dominance. The GB New Generation Handheld game console NDS developed by it brings the designer's innovation ability into full play and is also a representative of bringing outdated technology into full play in innovation. Yoki Junping once said in an interview that if a product is still not popular with advanced technology, it will eventually be a product of failure. He is very clear about the two sides of the existence of things. The opposite side of advanced technology just represents high cost and instability. Deliberately chasing technology may not be a wise choice. Balanced thinking from the perspective of obsolete technology is not necessarily not a direction to ensure a company's long-term development. It is understandable that the technology that is eliminated cannot be understood as a useless technology. Using mature or even well-known technology can first obtain the advantage of low cost and ensure the rationality and stability of goods, it is also not easy for competitors to foresee and guard against. It is this innovative idea that Nintendo's NDS has successfully defeated Sony PSP, which integrates many top technologies in the industry, by using the stale technology dual screen and touch screen that have been successfully applied for more than ten years. In the design of LED lights, this concept is still applicable. Some experts believe that in the evolution of incandescent lamps, fluorescent lamps, LED and OLED, and in the intersection of old technologies and new technologies, if designers can understand old things from a new perspective without asking about existing concepts, using existing technology in non-existing products has the possibility of creating new products. A good design does not have to have advanced concepts, but it must solve the problem correctly. For example, several tungsten bulbs full of nostalgic style appeared on the ceiling of Frankfurt pavilion, but the tungsten bulbs here are LED products. The application of old technologies in the new technology environment has been reflected in the design of early Japanese lamps. According to the data, in the early Meiji period of Japan, the Chinese candle lamps were still hung high with red lanterns, classical and dignified; The Western-style lamps highlight the dazzling characteristics, and metal materials and carvings are widely used. At this time, Japanese lamps and lanterns began to use tulle-like light-transmitting materials in candle lamps and lanterns, which can simultaneously play a multiple role of windproof, anti-glare and anti-reflection light. Zhang Xin, an associate professor in the Department of Architecture in the School of Architecture of Tsinghua University, pointed out that under the gradual change of human demand, lighting technology is at the stage of visibility, security, spatial organization orientation, and identity expression, towards the stage of expressing conceptual meaning, this also requires designers to grasp the direction of innovation. This can also be seen from the Frankfurt exhibition. The attractive booth provides more solutions and life experience halls, many of which are highly integrated with mechanics, optics and aesthetics, not just the display of advanced LED technology. Unexpected lighting scene demonstration and home atmosphere simulation are all reflecting our familiar living environment, such as OLED simulation room built by Sumitomo. Using new technology to create a better living space is the foothold of the innovative spirit. With the development of LED in outdoor indoor applications in recent years, the market has given designers a broad space to display, and the status of designers is becoming more and more prominent. As Shang Yaoqi, designer of Shanghai Yaming Lighting Company, said, LED products provide us with more conditions and designs can be more flexible and changeable. If the new technology of LED is combined with the already well-known space, mechanics, and even traditional art, culture, and materials, aesthetics, stage, and architecture, LED designers walking between old and new technologies have a wide road to innovation.
