/kloc-the question I asked 0/0 years ago, which is better, electrodeless lamp or LED lamp? Compared with LED lights, LED lights are better. 10 years later, I asked electrodeless lights or LED lights, which is better? There is no doubt that the technology of electrodeless lamp has opened more than a dozen streets of LED lamps, but LED lamps occupy a broader market share than electrodeless lamps. The reason can be seen from the development history of electrodeless lamp behind it.
At present, the technology of electrodeless lamp can't be compared with LED, especially the bright pigeon eye protection lamp under electrodeless lamp in Leites, Hangzhou, which not only saves energy, but also blinks stably, protecting more than 90% of eyes. The advantages of eye protection technology of bright pigeon eye protection lamp are too obvious, which is dozens of times higher than that of contemporary light sources. It is scientifically determined to have bactericidal effect.
Which is better, electrodeless lamp or LED lamp? We can see the advantages of electrodeless lamps from the following aspects:
1, electrodeless lamps can be ignited for a long time and used in irreplaceable places, while LED lamps are much inferior in this respect;
After years of long-term testing and inspection, the ignition life of electrodeless lamp can reach 654.38+ 10,000 hours. For places with difficult maintenance (such as high ceiling workshops, high-precision equipment workshops, tunnels, bridges, roads, energy, chemical related industries, etc.). ) and European and American countries with extremely high maintenance costs, its value and quality are highlighted.
2. Electrodeless lamps can be used in places with extremely high light color index, but the light color index of LED lamps can not meet the requirements;
For glare, color temperature, color rendering and other indicators, electrodeless lamp has been completely ahead of all kinds of lighting products through the improvement of lamp structure, reflector design and light source technology. It has won high praise from customers in high-precision workshops, food processing and sales areas, textile printing and dyeing processing areas, open-air tennis courts and other sports venues.
3. In places with high energy-saving requirements for electrodeless lamps, LED lamps are much worse than electrodeless lamps in energy-saving;
In terms of energy saving requirements, the electrodeless lamp has the characteristics of high initial light efficiency (the light efficiency of the light source exceeds 90lm/W) and small light attenuation after long-term lighting, which truly guarantees the excellent user experience of customers for 5 years.
4. Electrodeless lamps can be used in special lighting places, while LED lamps do not have this function;
Electrodeless lamp manufacturers have been committed to developing a wider range of applications and lighting places, and there are successful cases and significant user improvements in the fields of plant lighting (red and blue spectrum lighting), livestock storage lighting, supporting low-voltage solar energy systems, and DC emergency power supply system lighting.
5. The frequency stability of electrodeless lamp is beneficial to eye protection, while LED lamp has no advantage in this respect.
Many problems of domestic students' myopia are related to lighting, and LED lamps can't compare with electrodeless lamps in this respect.
Combined with the product characteristics, the successful application of electrodeless lamp in industrial lighting has promoted its marketing and promotion in this field rapidly.
Which is better, electrodeless lamp or led lamp? After comparison and summary:
1. The lighting of an electrodeless lamp is like sunlight. Using electrodeless lamp to illuminate and care for workers' eyes makes workers' work efficiency higher. Avoid dazzling effects of led lens, such as light spots;
2. All electrodeless lamps are guaranteed for 5 years, and the actual use can reach 10 years or more;
3. The current situation of LED, the low-priced quality is not good, and the high-quality price is 300w W W. The electrodeless lamp can easily achieve 2.5 yuan per watt, and the LED with the same effect is estimated to have a headache;
Since electrodeless lamps have so many advantages over LED lamps, why did they lose to LED lamps in the market? This requires a good review of the development history of electrodeless lamps in China.
At present, the global production of electrodeless lamps is mainly concentrated in China, which is consistent with the production environment of the whole lighting industry, mainly determined by China's industrial base, labor cost and market environment. The development of electrodeless lamps in China has gone through the following three stages:
The first stage: germination and brewing stage. Since 1990s, both Philips and OSRAM have introduced electrodeless lamp products. At that time, the stability, efficiency and service life of the products were all problematic, considering that electrodeless lamps might have an impact on their huge and core HID production and sales system, so they were not promoted. Philips electrodeless lamp is the prototype of high frequency electrodeless lamp. The luminous efficiency of the product is too low, and it has basically been delisted. There are still manufacturers in China, but they are basically transitional technologies. Osram's electrodeless lamp is the embryonic form of low-frequency electrodeless lamp now, and domestic enterprises producing low-frequency electrodeless lamps have developed on this basis. Osram still has this product, but it is no longer produced, and it is manufactured by domestic enterprises.
The second stage: the hegemonic stage. From 2004 to 2008, domestic enterprises began to set foot in the production of low-frequency electrodeless lamps, including Shanghai Hongyuan and Fujian Yuanguang Yaming, as well as other brands, such as Stendachang, Hoppeler, Changhong, Fengyun, Jiuzhou, Gem, Sonny, Hao Jie, Langlaifu, Pratt & Whitney and Guanhong, which are high-frequency and low-frequency, respectively.
With the passage of time, the quality of many electrodeless lamps has appeared problems. In fact, this is not the problem of the electrodeless lamp itself. The technical threshold of electrodeless lamps is relatively high. Some of these enterprises are only ballasts and some are only tubes, and they buy other accessories for assembly in the market, just like the LED industry now. But unlike LED, electrodeless lamp is an engineering product, which can't be used at home, so products with poor quality and stability can't survive in the market, so many enterprises with technical defects have fallen, which is essentially different from the LED market where "bad money drives out good money". In the electrodeless lamp market, it is impossible to survive without reliable products.
The third stage: the industry shuffling stage. Since 2008, with the survival of the fittest in the market, there are not many electrodeless lamp enterprises in the market now, and even fewer have the ability of sustainable development. They are all powerful brands of electrodeless lamps that can survive. Now the remaining brands are Electrician, Shanghai Hongyuan, Fujian Yuanguang Yaming, Changzhou Kaisen, Zhejiang Kaiyuan and Hangzhou Leites. Sonny, Stanford, Langlaifu and other enterprises mentioned above have withdrawn from the historical stage of electrodeless lamp development.
