Lighting is more energy-efficient than LED. Why is the market smaller than LED?

In the high-power field, LED products always have their insurmountable problems. Lighting is just acting as a 'substitute' role to solve the insurmountable problems of high-power LED products. At this time, as one of the people who have witnessed the rise and development of lighting, I always want to scream: 'Even without high-power LEDs, we still have lighting.' 　　 Why don't Philips and Osram push lighting?　　 It needs to be pointed out that lighting and LED were both born in the 1960s. Lighting is a great invention based on the wireless energy transfer theory of the famous American inventor Nikola Tesla, integrating power electronics, plasma science, and magnetic materials science across several different disciplines. Lighting and LED are like 'twin brothers who come togetherLighting can be divided into high frequency (2.65MHz) and low frequency (250KHz) according to the working frequency. The high frequency was invented by Philips, generally spherical and olive-shaped; the low frequency was invented by Osram, generally ring-shaped and rectangular. At the beginning, the lighting was not mature. The maximum power of high-frequency lighting was only 165W, and the maximum power of low-frequency lighting was 150W. Moreover, the two largest lighting companies in the world did not promote lighting as their main products. The reasons are: 1 , The application range of the product is relatively narrow, the main power is concentrated between 35-160W, unlike metal halide lamps, sodium lamps are as small as 35W to 10000W; 2. The light efficiency is not particularly high, 80-90LM/W, and metal halide lamps Almost, not as good as sodium lamps; 3. Due to the advantages of energy saving and longevity of lighting, some customers will definitely choose lighting. Then, the sales of metal halide lamps and sodium lamps of Philips and Osram will be seriously affected, and the huge investment in metal halide lamps and sodium lamps The production line will become 'scrap ironThe three stages of the development of lighting in China At present, the global lighting production is mainly concentrated in China, which is consistent with the overall production environment of the lighting industry. It is mainly determined by our country’s industrial base, labor costs, and market environment. Lighting is in China The development of the company has gone through the following three stages: 　　 The first stage: the budding stage. Beginning in the 1990s, Philips and Osram have launched lighting products. Since the product stability, efficiency, and lifespan were all problems at that time, and they all considered that the lighting might have an impact on their huge and core HID production and sales system, so they did not promote it. The lighting launched by Philips is the prototype of the current high-frequency lighting. The luminous efficiency of the product is too low. It has basically been delisted. There are still domestic manufacturers in the production, but it is basically a transition technology; the lighting launched by Osram is the prototype of the current low-frequency lighting. Companies that produce low-frequency lighting have developed on this basis. Osram still has this product, but it is no longer produced and is made by domestic companies.　　 The second stage: the stage of fighting for hegemony. From 2004 to 2008, domestic companies began to be involved in the production of low-frequency lighting, including Shanghai Hongyuan and Fujian Yuanguang Yaming. Others include Shidan Dachang, Obolite, Changhong, Fengyun, Jiuzhou , Gems, Sunny, Haojie, Longlife, Praites, Guanhong and many other brands, some are high-frequency and low-frequency, and the market is unprecedentedly prosperous for a time.　　 As time goes by, the quality of many lightings has problems. In fact, this is not the problem of lighting itself. The threshold of lighting technology is extremely high, and some of these companies are only making ballasts, and some are only making lamps. They buy other accessories and assemble them in the market. This phenomenon is just like the current LED industry. But the difference between lighting and LED is that lighting is an engineering product and cannot be used in homes. Therefore, products with poor quality and stability cannot survive in the market. Therefore, many technically flawed companies have fallen. There is an essential difference in the 'bad money driving out good money' in the market. In the lighting market, it is impossible to survive without reliable products.　　 The third stage: the industry reshuffle stage. Since 2008, with the survival of the fittest in the market, there are not many lighting companies in the market now, and there are fewer capable of sustainable development. Those who can survive are all powerful lighting brands, and now there are still brands remaining Electricians, lighting factory Tianji, Fujian Yuanguang Yaming, Changzhou Kaisen, Zhejiang Kaiyuan, etc. The above-mentioned companies such as Sonny, Stantec, Longlife, and Shanghai Hongyuan have already withdrawn from the historical stage of lighting development.
