In recent years, our country has been promoting the use of energy-saving lamps through a large amount of manpower, material resources and financial resources. With the elimination of incandescent lamps, the market that has been “thrown†has brought huge development space for energy-saving lamps. More and more lighting companies have launched energy-saving lamp products to seize the remaining market.
At present, energy-saving lamps are the most widely used incandescent lamp replacement products for consumers. Its efficiency is more than five times that of incandescent bulbs, and its average life expectancy is about 8,000 hours. It is mature in technology and has good matching with lighting and lamps. It is a simple and relatively low-cost alternative. However, energy conservation and environmental protection should complement each other, but in the energy-saving lamps, the two have reached the opposite side. The problem of mercury contains the destiny that the energy-saving lamps will eventually be replaced: an ordinary energy-saving lamp contains an average of 0.5 mg of mercury. The immersion of these mercury into the ground can cause pollution of approximately 180 tons of water. If the waste energy-saving lamps are not properly disposed, it is likely to become an "ecological killer", and the waste energy-saving lamps have also been improperly handled for many years. Even today, there are no suitable policies and measures.
Analysis of the status quo of LED lamps
LED is a low-voltage semiconductor point-like cold light source. The "theoretical advantage" of longer life, high efficiency, energy saving and environmental protection has passed the test of practice. The performance parameters of LED light source are not as previously said. In the improvement, but "further improvement", the overall development prospects of the LED industry are generally optimistic.
With the phasing out of incandescent lamps and the state subsidies for energy-efficient lighting products, the LED lighting market is already accelerating. The tentacles of LEDs are gradually deepening into the home lighting market, but the current price issue of LED lighting products is still the most important factor hindering the large-scale entry of LED into the home lighting market. In terms of price, the retail price of the 1.2-meter-long, 21-watt LED tube on the market is normally above 200 yuan, while the traditional fluorescent tube of the same length and wattage is basically less than 10 yuan; in the replacement cost of incandescent lamps, LED bulbs and traditional energy-saving lamps also have a price difference of at least 8 times under normal conditions. Such a price gap is naturally the biggest obstacle to the entry of LED lighting into the home environment. Many lighting dealers also said that LED home lighting is still in the promotion stage, and more consumers tend to buy energy-saving lamps with relatively low prices. In the home market, energy-saving lamps are still the biggest rivals for LED lighting products. And home lighting is always an area where energy-saving lamps excel.
LED lamps are undoubtedly the direction of the development of lighting fixtures in the future. It is worth pondering that with the support of the policy, the LED industry has doubled its growth rate for many years, but LED lighting has never been able to start the civilian market. In addition to the high price, the quality is not stable, the price is not high is the main reason. In fact, in the past few years, the price of LED lighting has been decreasing at a rate of 35%-50% per year. I believe that in the near future, the price of LED lamps will fall to the range that every household can accept. The era of lighting has arrived.
"Ene also friends" energy-saving lamps accounted for the trend of mainstream LED lights
In the trend of traditional lighting to LED lighting transformation, some manufacturers are inevitably eliminated in the market competition, but some are based on technology and steady development. After all, any emerging industry must withstand the test of the market to become more mature. From the perspective, this is also the process experienced by any traditional light source. Traditional lighting and LED lighting are the representatives of different stages of development. The rapid development of the LED industry and the promotion of the government do not mean that LED is the nemesis of traditional lighting. .
Recently, people in the industry put forward on Weibo: "Don't regard LED and traditional lighting as a simple alternative relationship, let alone split it. If you do this, you will only bury the LED lighting industry. LED and traditional lighting are the relationship between inheritance and development. This kind of thinking method should be used to study the flexible and changeable characteristics of LED light source combination, to study the application of LED light source and luminaire, to find the most suitable use of the land to shine. Just look at the LED light source and illumination from the perspective of “alternative†It is childish and superficial."
The catalyst is a deoxygenation catalyst supported by precious metal (palladium) on active alumina. It is mainly used for deoxygenation in hydrogen and hydrogenation and deoxygenation of inert gases such as nitrogen, nitric oxide, nitrogen dioxide and argon.
