Baoding city to speed up the popularization and application of outdoor led spotlights

Recently, the Hebei province Baoding city to support the introduction of the new deal, the independent innovation products included in the directory of LED government procurement, procurement priority energy-saving effect is more than 70% and the demonstration project to test local energy-efficient LED lighting products, outdoor led spotlights, to speed up the popularization and application of LED lighting products.

Baoding City financial subsidies way to accelerate the popularization and application of LED lighting products, at the same time, the government investment in new, alteration, expansion projects in need of lighting products, give priority to the use of government procurement directory of LED products.

It is understood, outdoor led spotlights, the city will promote the road, large public buildings in areas such as lighting products to upgrade, to the urban transformation and new rural construction as the turning point, promote LED lighting indoor light into the area of residence. According to the plan, by 2015, Baoding City Road, streets, outdoor led spotlights, public buildings and other fields of the LED popularity rate will reach 100%, government offices, libraries, stadiums and other public facilities of LED penetration rate reached 98%; the square, parks, scenic spots and green lighting LED penetration rate reached 98%; indoor lighting LED penetration rates reach 90%. The city’s annual 2200kwh of electricity is expected, outdoor led spotlights, section coal 6820 tons, about 18000 tons of carbon dioxide emission reduction.

In the traditional LED lamp production process, light electric detecting link time-consuming and labor-intensive, generally adopts sampling or exemption form to carry out the operation, product quality is difficult to guarantee. For the groundbreaking integrating sphere test technology into production process of LED lighting, LED lamps in line inspection, led high bay multilayer screening of light and color, power and other parameters and can automatically form file, for each of the LED lamps quality identity data file management and traceability of CIE, IEC, Energy Star, NIM and other authoritative testing standards.

Incandescent lamp is not a easy flat to exit, outdoor led spotlights catching up

With the approaching of the ban on the sale of incandescent lamp, more and more people are entrapped into the “Crazy” consumption of incandescent lamp. According to reports, a British lady is looking for the traditional light bulb, and trying to accumulation such bulb(led high bay), so that she spent 7000 pounds in one time.

As a matter of fact, as begining of the EU ban as the year of 2009, Europe appeared the phenomenon of panic purchasing, collecting traditional bulbs. In 2009 Austria, the traditional light bulb sales exceeded 30000000, increased 5000000 compared with the normal year. In some TV shows such as Germany also broadcast the lens of numerous residents purchasing a large number of traditional lamps, no outdoor led spotlights, a few businessmen also adopted restriction measures. Previously, all the businesses have increased the inventory of incandescent lamps.

This is also the reason that some businesses insisted on selling traditional light bulbs. London has a electric company indicating refused to sign the British retailer lock-up agreement. Each of the traditional light bulb is priced at 2.2. One sales manager said:”many people want to buy the old light bulbs, so the next generation can continue to enjoy the same soft lights. Right now, UK has not appeared the black marketing of traditional lamp, but with the decreasing of inventory, the marketing of outdoor LED Spot Lights will appear soon.”

The relavent investigation by The European Union pointed out that using energy saving lamp eg,outdoor led spotlights to replace the traditional light bulb can deduce 15000000 tons of carbon dioxide emissions. On traditional lamp energy consumption, less than 15% is used for lighting, the rest are changed to heating energy. While the 50% consumption of energy-saving lights can be used to lighting.

The energy efficiency rating is the focus for outdoor led spotlights

The power factor is a measure of the efficiency of electrical equipment level of thecoefficient. Low power factor, equipment reactive power, thereby reducing the efficiencyof electricity use, an increase of the loss of the power lines, amounting to less than the energy requirement. 13W products such as lead ball lighting, led high bay, with a nominal power factor of 0.6, the standard requires the actual power factor shall not be more thannominal value low 0.05, that is not less than 0.55 measured only .520 to .527, outdoor led spotlights, but does not meet the standard requirements. The test, a sample power factor does not meet thestandard requirements, accounting for 2.5% of the total number of samples, namely:lead ball lighting 13W. According to experts, the power factor is not up to the main reason is the lamp electronic ballast component selection and circuit design caused by the irrational, outdoor led spotlights, there are some manufacturers to use inferior components to product performance can not achieve the design level.

The luminous efficiency is the ratio of the light emitted luminous flux and power consumption, while the luminous flux and reflects the light emitting intensity of lightperformance directly reflects the product is energy-saving. The project is not up to reflecta sample of low luminous efficiency or luminous intensity is not enough, outdoor led spotlights, up to lessenergy-saving, money-saving effect. The lead ball lighting 13W product standardsrequire that the initial light effect not less than 44 lm / W, but is actually only 36.65 lm / W~ 41.60 lm / W, does not meet the standard requirements.
Energy efficiency labeling that the product energy efficiency rating and performance indicators such as a logo. The level of energy efficiency labeling The lower the number,the more energy-saving. Virtual standard energy efficiency rating would misleadconsumers, but also unable to achieve energy saving. Star 5W products such as Trinityresidence, with a nominal energy efficiency rating of 2, in accordance with nationalstandards of its initial light effect not less than 46 lm / W, outdoor led spotlights, but is actually only 29.84 lm / W~ 34.49 lm / W, fell far short of the requirements even China’s energy-efficiency labelingof three requirements of the initial light effect not less than 36 lm / W.

The plate cooling of the outdoor LED spotlights

LED chip is characterized by high heat in a minimal volume. The heat capacity of the LED itself, it must be the fastest heat conduction out, otherwise it will produce a high junction temperature. Heat leads to the chip outside, a lot of improvements in the outdoor LED spotlights chip structure.

In order to improve the heat dissipation of the LED chip itself, the most important improvement is the thermal conductivity of the better substrates. Early outdoor LED spotlights only Si silicon as the substrate. Later changed to sapphire as a substrate. The thermal conductivity of the sapphire substrate is not very good (at 100 ° C is about 25W / (mK)), Cree’s silicon carbide silicon substrate in order to improve the cooling of the substrate, its thermal conductivity (490W / (mK), nearly 20 times) than the sapphire. And sapphire silver plastic solid crystal, the thermal conductivity of the silver plastic is also very poor. Silicon carbide only drawback is the cost more expensive. Cree is the production of silicon carbide substrate led high bay lights.

Using silicon carbide as a substrate, can indeed greatly improve its heat, but its cost is too high, and patent protection. Recent domestic manufacturers began to use the silicon material as a substrate. Because the base of silicon materials not subject to patent restrictions. And the performance is better than sapphire. The only problem is the expansion coefficient of GaN and silicon that much difference, but prone to cracking, the solution is to add a layer of aluminum nitride (AlN) as a buffer in the middle.

Hot invisibility cloak technology will seperate LED outdoor led spotlights?

Physicist Organization March 26 in the latest issue of “Optics Letters” magazine, the French scientists confirmed that many of the principles of optical invisibility cloak technology able to develop the transfer object to focus on certain hot thermal stealth or a regional “hot invisibility cloak.” The scientists said that the latest technology is expect ed to better control the heat dissipation in electronic devices, outdoor led spotlights, is also expected for the aerospace and solar technology.

At present, the progress achieved in the field of invisibility cloaks are based on the transformation of the basic principles of optics, which relates to the use of metamaterials and use it to allow light to bend, outdoor led spotlights, around the propagation of light in a space rather than through the space. For this reason, the Aix-Marseille University and the French National Scientific Research Center (CRNS), a joint researcher Sebastian Guna You led the team decided to clarify whether the same method can be used for the thermal diffusion.

Guna You said: “We conducted this study the main objective is: to use the conversion of optical tools, outdoor led spotlights, the success has been achieved in the field of sound and light ‘invisible’ to control the proliferation of hot.”

Guna You explained the basic principles of the latest technology and optical cloak, but there is still a critical difference. To date, the cloak to the trajectory of the operating wave for the center, including light and sound waves, LED high bay, but the biggest difference of the thermal field of the wave field contains the physics of the phenomenon of thermal diffusion rather than wave propagation.

The Guna You said: “is not a heat wave, it just spread from high temperature to lowtemperature, outdoor led spotlights, therefore, in these two areas from a leading role in mathematics and physics is very different principle. For example, the wave energy long distance travel attenuation is small, but a very limited range of temperature diffusion.

In order to create a hot invisibility cloak, Guna You and colleagues will be converted to optical principles of physics applied to the thermal diffusion equation and found that “hotcloak of invisibility” technology can be achieved.

The Bashar wife due to the outdoor led spotlights crazy online shopping EU sanctions blacklist

World Wide Web Reporter Guo Wenjing reported that the British media exposure provided by the classification opposition rumored the Bashar couple private messages. According to the message content, Bashar al-Assad’s wife Asma preferences to spend heavily outdoor led spotlights online shopping designer goods. The EU will put her in the sanctions blacklist, including imposed a travel ban led high bay and other sanctions.

The British “Daily Telegraph” reported on March 19 said it has 114 Syrians and 38 classification the organization is included in the blacklist of EU sanctions, the European Union to freeze its assets and bank accounts in the EU member states. Today, the 36-year-old Bashar’s wife and other family members will also be added to this list of sanctions.

The EU diplomat said Asma’s decision on sanctions blacklist to be discussed in the meeting of EU foreign ministers meeting in Brussels this week, five (23). Many Bashar family members will be added to the blacklist. “Diplomatic sources said. The “Daily Telegraph”, the European Union and British officials believe that this measure will strengthen outdoor led spotlights the regime of Bashar al-Assad “constraints”.

Reported that Asma continue to retain their British citizenship, then the travel ban will not prevent access to English. But, like other officers already in the column, Asma is still very likely have been the EU’s travel ban.

The “Daily Telegraph” said that since the classification opposition announced Bashar couple of e-mail, Asma Bashar core group’s role will increasingly look at. According to the published e-mail, Asma preferences spend heavily net purchase brand-name merchandise, outdoor led spotlights including jewelry, furniture, crystal chandeliers.

PESD for LED outdoor led spotlights

LEDs are semiconductor devices, are more sensitive to static electricity to prevent static electricity and eliminate static electricity work to do, especially for white, green, blue, purple outdoor led spotlights.
