In the domestic market two years ago, LED lights are still more in the topic, and at present, many models with LED lights have been mass-produced. Brands including Volkswagen, General Motors, BMW, Mercedes-Benz and Ford have launched new models of LED front and rear lighting fixtures with brand recognition effects, which have successfully attracted many consumers. Before 2010, the average growth rate of the domestic LED automotive lighting market was 13, and in recent years, the LED lamp market has grown at a rate of more than 40. Last year, the domestic automotive lighting market exceeded 20 billion yuan. It is predicted that there will be 245,000 sets of LED car headlights in the domestic market this year, and this number will reach 907,500 sets in 2016, which will more than triple the growth, while the taillight application with LED function will be more For a wide range. According to the Ministry of Industry and Information Technology, as of the end of 2015, automotive lighting needs to meet the carbon dioxide emission reduction targets. As a recognized representative of low-carbon and environmental protection, LED will naturally be included in the scope of automotive lighting upgrade and transformation, becoming the darling of automotive lighting, thus forming a market demand of tens of billions or even hundreds of billions, LED automotive lighting market prospects Can be expected. Because LED lights have a cold light source, they have the advantages of low power consumption and long life. The power consumption is only 1/10 of that of traditional lamps, which can save fuel consumption. If the daily energy-saving lamps are used, the energy-saving lamps can save 4/5 more energy than the incandescent lamps, and the LEDs can save 1/4 more energy-saving lamps. In the car, the same daytime running lights, the energy consumption of the LED components is only The halogen lamp is 1/20 and has a service life of 5 to 10 years. In addition, LED components have the advantages of small size, compact and easy layout and design, leaving car manufacturers with a shape in the car design. The vast space breaks the shackles of the past lighting system to shape innovation, and meets the needs of the appearance of the car, which also brings business opportunities to the domestic LED lamp industry. In February 2011, the EU required all new models of cars and minivans to be equipped with daytime running lights. In addition to the EU, other countries have begun to regulate the new cars of all types of vehicles to install daytime running lights. Relevant policies of various countries have been introduced to accelerate the popularization of LED lights. Industry experts say that daytime running lights must maintain brightness while the vehicle is in motion. Because LED light source has the advantages of low energy consumption and long life, considering the trend of driving safety and energy saving demand, it is an inevitable trend for manufacturers to develop LED daytime running lights. It can be said that the LED light source is an ideal light source, but the LED replacement is still in need of a transition period. At present, LED headlights are mainly concentrated in a few high-end models, such as Audi R8 and A8, Mercedes-Benz CLS, BMW X6M and the new BMW 7 Series. China's auto industry has few independent brands, most of which are medium and low-end cars. There are not many LED lights. At present, only high-position brake lights and side turn signals use LED light sources. In addition, because of the problem of illumination distance and brightness, LEDs are rarely used for heads. Lighting. Due to the high cost, technical and regulatory factors, LEDs are still immature as automotive headlamps, and at least for the next three to five years, halogen and xenon lamps cannot be fully replaced. However, I believe that with the continuous decline of LED costs and the simultaneous improvement of technology, the automotive industry will be more widely used, LED lights will become more secure and intelligent, and there will be more and more advantageous technologies. Leading the development of automotive lighting.
Closed Cooling Tower
Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
