Scientists develop new spray materials can be applied to the future of LED lighting

Recently, scientists have recently developed a spray can into a wall radiator. University of Nottingham China Campus researchers invented this technology, they developed a spray can absorb heat during the day, when the temperature drops slowly release it.

This breakthrough technology will effectively reduce energy consumption, save a lot of money, expected to be 35 percent effective in reducing indoor heating costs, it will be on sale within the next two years. At present, this spray is called 'non-deformed material change in energy storage (PCM)', the heat source is distributed excess room heat.

When the indoor temperature reaches a certain level, the spray material will store extra calories, for example: suitable for room temperature of 22 degrees Celsius. It has a ubiquitous application, adapted to Brick walls, and walls inside the wallpaper . University of Nottingham in the UK Sustainable Energy Center lab, researchers have been condensed into a large spray material thin coin.

By Joe - Dake Wa (JoDarkwa) and colleagues, Professor Oliver - Su (OliverSu) cooperation to complete the study, they said, as this material can work as the spray, on surfaces to form a micro-thin layer. At a certain temperature above the spray of particles to melt, they are not the formation of water droplets, but in the form of a special cover. After these substances will become solid, the heat distribution in the room.

Scientists believe that this spray can be used for the construction of new building materials, and effectively save energy. At the same time, they stressed that this will significantly reduce carbon emissions. Dake Wa professor, said the construction industry will generate more trade than the rest of the world's carbon emissions, even more than air flight. In some developing countries, the construction industry is the highest energy consumption unit, and emit large amounts of pollutants. If this material can be widely used, it will significantly affect the world, help reduce carbon emissions.

But this is not out of the spray material and air-conditioning , this is because people still need air conditioning to control humidity and air circulation. They can only reduce emissions of excess house heat. The team believes the future of the material can be applied to solar cell panels and LED lighting .

Currently, they are studying what kind of paint can be used in conjunction with the spray material, and no environmental impact. At the same time, they will explore more green way, and thus effectively reduce the world's carbon emissions.

 

Modular LED lights to bring a new dawn lighting market

The modular LED lights bulbs has been difficult birth, because in the heat, water, light, components can easily be replaced with any sodium lamp housing adapter and many other key technical barriers exist, preventing the LED street modular form.

LED lights in the domestic market from the original Sound and Fury gradually attributed to silence the occasion, LED lamp to domestic and international market has brought a new dawn.

    First, the thermal performance, the company developed the green times with completely independent intellectual property rights of nano-heat paint , the paint sprayed on the surface of the radiator, the radiator cooling performance can make on the basis of the original 30 percent. In addition, the lamp cooling is also used on the 'up and down the transparent use of natural air convection' own patented technology. In this patented cooling technology for two after the LED lights, LED lights in the outdoor environment, the actual use of the constant temperature below 45 ℃, the temperature is too high to solve the LED street light failure and affect the life of the world's problems, making both more high-power LED lights, green companies are able to guarantee the times ten thousand hours of its use does not appear light attenuation.

    Secondly, in the waterproof performance, with a light green Time Inc. COB package is also a light source to create a unique positive and negative design patent in the substrate above the package, completely solved the problem of source water. As an independent light source may be fixed by screws and the retainer and other fixed means fixed on the radiator, and through proprietary technology that allows each individual source of illumination angle can be adjusted according to actual needs, sources of power can be be adjusted as needed, the LED street lamp light source to achieve a completely modular, easy maintenance or replacement.

    Third, other structure, Time Inc., the green LED lights power , drive, heat sink are designed to be stand-alone installation and removal of the modular structure, but also a variety of modeling sodium on the existing light housing for simple processing transformation After the adaptation phase, sodium lamps to maintain the integrity of the shell and beautiful, save a lot of replacement cost, for urban street reconstruction of great practical significance.

BDO intend to invest 3.5 billion to forge LED industry chain

Domeatic LED industial grant BDO published on 28th that its 3.5 billion investment plan has approved by CSRC(China Securities Regulatory Commission). This is the second large-scale output capcacity of BDO on LED lights suppliers industry after their addition of arising money 1.5 bilion yuan at last Novermber.

Welcome the world of rapid development of LED lighting

hang Yanan: the topic of yesterday, we continue to be concerned LED lights manufacturers, yesterday we mentioned the rising prices of rare earth, to LED Lighting Industry development has brought some opportunities the other can also be noted that many countries will be phased out over the next few years, the traditional incandescent, LED is not the will to bring a broader space?

Du Bin: We know the characteristics of incandescent lamps, although low cost, but alternative energy conversion efficiency is very low, with each country now for energy saving awareness is growing, so that now many countries are beginning to have lists a timetable and set a few years, prohibit the sale and use of incandescent bulbs in the history of human civilization long enough to occupy the traditional incandescent bulbs may usher in a curtain, an alternative should be based on the corresponding LED, led by some of the more efficient New Energy. We are aware that the cost of long-term use and habits, we have become accustomed to using the traditional incandescent bulbs, it is characterized by very low, so that the lighting market, which is now in, or account for more than enough share of the future, as schedule the introduction, about five years, these traditional light energy will be phased out by some new and efficient alternative, make a new type of LED lighting, a very large market space to replace the lighting should be generated by the market demand is very large .

And we can put some of the far-sighted, top of the Japanese, as I read data to the whole of Japan in June LED lights Bubble proportion of all light bulb sales have reached 43.5%, if more serious power rationing in some areas, this proportion can reach 50% higher. For now look at this trend, but now the ratio is getting higher and higher, or a graded process, so walk in front of some of the situations in Japan and has a relationship, relatively high domestic electricity, energy saving awareness is relatively strong. So from very early on, the policy on the implementation of the mid-subsidy policy, the development of the whole market is indeed faster, and now Japan has been associated very low cost LED bulbs, sold very cheap, so that the market share of more large.

As the power the United States, there is a prior forecast, next year, have started the LED market, to about 15 years, the entire class of LED lighting sales could account for its entire lighting market 3 / 4, should be is also a very big piece of cake, we look at European countries, the EU's schedule is actually more than just us that some of the other countries may be much earlier, it should be said is coming up, and it introduced the amount of subsidies very large, may account for total sales of the lamp 30% -50%, and can say that the future will also have a very large substitution effect, the signs are that the future of LED may usher in a period of rapid growth .

LED bus stop lighting systems are particularly suitable for rural areas?

After nearly two years of the pilot, Hangzhou Xiaoshan region currently has 54 rural bus stop using solar power led lighting system. Xiaoshan passenger transport infrastructure headquarters confirmed that this lighting system is the latest in the next year before the Spring Festival, the region has completed the transformation of the rural bus stop in use.

Lighting system especially suitable for rural areas

It is reported that rural bus stop, no lighting, it is prone to the site to be touched or been touched Yexing Ren and other accidents. To some extent, bus stops lighting lighting even more important than the road. However, due to its location in rural areas, rural bus stop, take more trouble with the municipal people's power, then the cost of electricity is also high.

Back in September 2008, Samick line Xinyi village bus stop on both sides of roads, installation of LED lighting systems, this is my first trial area LED lighting system. This lighting system consists of solar power and low-carbon of LED lights. Main function is to use photovoltaic technology to convert solar energy into electricity. LED is a semiconductor light-emitting diode abbreviation. In the LED lighting systems, photovoltaic electricity will be stored in batteries, then the supply of LED lights, complete with its light emitting characteristics. This system, solar energy is completely clean, light-emitting diode is an environmentally friendly, energy saving, power efficient solid-state light sources. LED lighting is the next generation of new sources of energy and the perfect combination.

Xiaoshan passenger transport infrastructure Jin Wei, head of the command are said to use LED lighting in rural public transportation system not only solved the difficult problem of electrical connection sites, even more gratifying is that this system was originally designed for the 7th consecutive rainy days as usual to generate electricity. Last year, Xiaoshan nine consecutive rainy days, at night, bus stop lighting systems to work as usual.

Stops in each province costs 3000 yuan

Jin Wei calculations are to reporters, the original bus stop site uses the fluorescent lighting. A 8 m bus station, for example, to install fluorescent tubes is 30, each fluorescent lighting 10 hours per night, the bus stops a year in electricity (commercial electricity prices) needs to 4489.5 yuan.

Use of LED lighting systems, using solar power technology, no electricity costs. However, this system was the battery replaced once every three years, and to install security devices, this is a major expense. According to the staff, for this system is 12 volts, will not cause injuries to passengers.

According to reports, the half of the transit site uses LED lighting systems, electric lighting, the other half still received the same time lighting, LED fluorescent lamp night power consumption of only about 30%. Year, the use of LED lights to save electricity bus station is about 3,000 yuan.

It also is not fluorescent tube replacement cost. Fluorescent tube life is generally two to three years, the cost of each lamp to buy $ 8. The LED lamp life of 100,000 hours, according to the design for 20 years without replacement. LED Lights Lamp replacement cost is not generated by the number of pens.

The end of September there are 580 sites, "light"

In the early 54 pilot rural bus stop in New Street and Town have a pilot up to justice, each with 10, Puyang, eight, six Canton Town, temporary Town, Nga town Ning around town all four, wearing the village and town on the river 2.

It is understood that the end of September this year, 580 rural bus stops will be installed on the LED lighting system, until next year before the Spring Festival, the district soared to 600 rural bus stop, the cost savings will be considerable.
