To commemorate the 100th anniversary of the revolution held the first of sun yat-sen cultural festival opening ceremony, the use of modern technology and Chinese traditional culture the idea of combining, in zhongshan toki jiang square in creating a piece of the solar powered led street lights carrier “China zhongshan” print.

 

democracy and prosperity. This revolution over China about two thousand years autocratic monarchy, is a great revolutionary movement. The revolution in modern China is more fully in the sense of bourgeois-democratic revolution. Is it political, ideological brought to the Chinese people do not underestimate the liberation of the role. The concept of democratic republican revolution makes thorough popular feeling. The anti-imperialist and anti-feudal struggle to the revolution as the new starting point, deeper, more large-scale carried out.

 

“China zhongshan” seal of the creation, planning, design, to the realization of the whole application scheme is epic proportions, achieve a breakthrough solar powered led street lights application. “China zhongshan” four characters to ZhuanTi text outlined a traditional Chinese seal, text height up to 16 meters, the whole plane with arc arc length 54 m. Novel architectural design and automatic control and the perfect combination of mechanical structure, the present technology embodies in solar powered led street lights screen, through the automatic control and the combination of mechanical design, display with folding fan in the day to be automatic contraction principle, night can be spread, and eventually embodies the Chinese traditional art of lettering of the time-Yin and Yang. Designers tried to used led high bay to replace solar powered led street lights but finally failed. Otherwise, led high bay light also can be treated as a substitute.

How to protect the LED household lights

 

How to protect the LED household lights

 

We first thought was the protection of the LED fuse, the fuse is a one-time, and the reaction speed is too slow, not only the poor actually use a lot of trouble, so the fuse is not appropriate for the finished products of LED household lights are now mainly in the glory of the city engineering and lighting engineering. Actual demand, we have done a lot of experiments, and in accordance with the requirements of the project summed up to have the characteristics of the LED protection circuit, it is very demanding: can start immediately to protect beyond the normal use of current, so that the LED supply pathway was disconnected, the led high bay supplier and power supply can be protected, normal and then throughout the lamp can automatically restore power supply does not affect the LED, the key is because it is a civilian products, added circuit cannot be too complex volume cannot be too large, low cost. These requirements are contradictory, mutually conditioned, it was very difficult to implement.

 

These reasons will cause the LED current rise abruptly, and soon the LED chips will be burned due to overheating. According to our experience, the majority of the LED burned poles short-circuit, a small part is open circuit. Each LED is about the pressure drop of about 3.2V, and burnt it if the circuit LED strings do not shined. If this short-circuit voltage were transferred to other LED, resulting in greater current of the other LED household lights and other LED will be faster burned, and even critical power. Was little damage on the very easy to cause a big accident. The LED is usually installed in high places, the installation is not easy, even harder to repair. LED household lights protection is the actual demand, but there is not attention, is a lot of frustration there is no way to deal with the problem.

The radiation of led emergency downlight is out of the limits of standard

 

The radiation of led emergency downlight is out of the limits of standard

 

Recently, there have been media reports, the market almost all the led emergency downlight at close range of electromagnetic radiation in excess of the relevant provisions of the state on the electromagnetic radiation protection, which led to the concerns of consumers.

 

Before the same period a burst seen in the media, led emergency downlight radiation, but our home, these table lamps, bedside lamps, lighting lamps “I use are energy-saving lamps. If the true radiation, long-term brachytherapy will have a lot of harm. I wanted to ask you Is there any way to reduce or as much as possible to avoid the damaging effects of such radiation?

 

A Shanghai TV station recently reported that from the regular channels, they purchased 10 different brands of led high bay lights, to led emergency downlight benefits and the physical and chemical environment, Chinese Academy of Sciences, Yao Yu, Director of the Center invited the senior engineer of the Ministry of Environmental Protection Radiation Environmental Monitoring Technology Center, the use of professional equipment to detect the results show: all brands of energy saving lamps in the range of 10 cm, the electromagnetic radiation values ​​are all more than 200 volts per meter, including a electromagnetic radiation is as high as 1600 volts per m. Existing national electromagnetic radiation protection, public safety exposure value be less than 40 volts per meter, which means that all led emergency downlight to be detected at close range radiation values ​​are seriously overweight. Ministry of Environmental Protection Radiation Environmental Monitoring Technology Center senior engineer beneficial to the Yuan

Tianjin: How to find the balance point between the main LED lighting and the high price

 

Tianjin Haiyu lighting person in charge said: Overall, main LED lighting industry has an advantage, and the prices it is still not enough on its increasingly high demand, customers not only value is the energy saving effect, but the price is also attached considerable importance their principles out the least money, buy the most affordable energy-efficient products, but this is often in conflict. For example: the same two LED manufacturers A and B, Company A imported chips, CREE or Philips warranty for three years.

 

The face of the current market, in order to truly enter the market for main LED lights manufacturers to enter the well-known brands in addition to those well-known and excellent brand, like the well-known brands that come into the market turns out to be not an easy thing . Production of low-end products, for fear of affecting their reputation, the production of high-end products and competition, but Company B, a dilemma. However, LED manufacturers A still has right to produce their led high bay lighting products without any worry about the high price and competitions from other LED manufacturers.

 

Manufacturers should be how to face, I think the main high-end products, because the era of progress, common sense will grow, they will eventually understand and accept the high price of high-end products. For the manufacturer, the product knowledge to be a popularization, there is the sales staff to strengthen the training of professional knowledge and communication skills improved, so that they can very smooth very confident to communicate with customers, do not have our products in your the general idea. “

Common faults for led solar street lighting system

 

Common faults for led solar street lighting system

 

The first case for the instrument panel of the led solar street lighting system is lit, there are two possibilities, an insufficient amount of oil the engine cannot be the complete lubrication of oil, under normal circumstances, the oil does not consume a lot of, so there may be leakage of engine oil. The second oil pump pressure and you should as soon as possible to stop to avoid traffic continue to operate without oil lubrication conditions resulting in engine damage.

The second scenario is the dashboard of water level lights, due to the water tank is not no reason to reduce cooling system problem occurs, there are two possibilities, first, somewhere in the system water leakage, and second, the temperature is too high The led solar street lighting system pressure water squeezed out. If the tank leaks can be temporarily to the vice water tank, add water, and then try to open a nearby repair shop technician handling. The location of the vehicle with various sub tank is not the same, it is recommended that the owners should refer to the owner’s manual. Keep in mind is that due to high engine temperature, do not easily open the radiator cap in order to avoid the instant the smoke vapor damage.

 

If the water temperature of led high bay lights Quefei above, the heat with the cooling fan must immediately stop driving, or the temperature suddenly rose, and pressure change stool causes the coolant into a high-pressure steam from leaking out, and also led to the engine cylinder head deformation or cylinder head gasket is damaged, the vehicles that would take 1-2 days to repair.

LED street lights occupy 20% of total lighting export

 

Last year, the lighting of the city’s export value of about $ 1.345 billion, essentially flat year on year, but energy-saving light export volume has soared to become one of the highlights of the lighting exports. It is reported that nearly 85% of the lighting business in the city has set out to develop the design of the T8 LED street lights source or led high bay lights, and with the LED to achieve the upgrading of product structure.

 

As one of the main export commodities in the city’s lighting products last year exports rose flat, but the energy-saving light source has soared to become one of the highlights of the lighting exports. Inspection and Quarantine Bureau research for T8 LED street lights, close to 85% of the lighting companies have set out to develop the design of the LED light source or lighting, with the help of the LED to achieve the upgrading of product structure.

 

According to statistics, the city in 2011 exports of lighting products inspection value of approximately $ 1.345 billion, a decline of 0.2 percent compared to last year’s annual export of 2011 LED lights 1232 batch, the value of $ 40,120,000, an increase of 25.4 4470 batch% annual export of energy-saving lamps, a value of about $ 268 million, two types of energy-saving products export value accounted for 19.9% ​​of the lighting of total exports, compared to last year grew 3.5 percent share. From the current regulatory situation.

 

Annual exports in 2011 after the transformation of the Huayi Lighting LED lamps 113.2 million U.S. dollars, an increase of 335.4%, and quality products successful T8 LED street lights into the Macau hotel renovation works.

Dimmable led street light is no longer a myth

 

Dimmable led street light is no longer a myth

 

Ever since mankind realized must do everything possible to energy conservation, in order to solve the pressing problems of atmospheric warming, how to reduce electricity for lighting as an important issue on the agenda. Because 20% of the total energy consumption of electricity for lighting. Fortunately, energy efficient dimmable led street light, the LED itself than more than five times that of incandescent lamp, energy-saving fluorescent lamps, energy-saving lamps also about twice, unlike fluorescent lamps, energy saving lamps as mercury. If you can take advantage of dimming to energy conservation, it is also very important means of energy-saving. But in the past all the light sources are not easy to achieve dimming and easy dimming is a great advantage of the dimmable led street light.

 

Because on many occasions, in fact, do not need to turn on the lights or at least not so bright, but very bright light, such as midnight to dawn hours of street lights; subway cars from the ground to open the car to the outskirts of the ground lights; more common in a sunny office near the window, schools, factories, such as fluorescent lamps are also opened there. These places every day do not know a waste of electricity! The past because of the high-pressure sodium lamps, fluorescent lamps, ceiling lamps, energy saving lamps cannot dimming, only to forget it. To switch to led high bay, you can freely adjust light, electrical energy can be saved! So for lamp dimming, the dimming is not the main applications of the family wall, the market is also very small. But demand dimming of street lights, offices, shopping malls, schools, factories, it is more important occasions, not only a huge market, and considerable energy saving. These occasions do not need manual dimming, but auto-dimming, intelligent light!

The future development for high efficiency led lighting

 

The future development for high efficiency led lighting

 

Have already said that the best LED dimming is a simple PWM generator PWM dimming using the PWM dimming can be installed in the wall switch, and then use a potentiometer to control the PWM dimming ratio in order to achieve. To bright light switch off, then you need to add a pair of lines. It is not compatible with the original wall of the high efficiency led lighting switch leads. The lead of the led high bay lighting technology switch is only 2, you can while dimming can switch. This advantage is difficult to be compatible. But actually, truly the most commonly used dimming lamps table lamp or floor lamp dimmer switch are installed on the power cord is not a wall, that just do not care to take advantage of the wall of the two leads. In other words, the tone of the PWM alone can be directly applied to Dimmable high efficiency led lighting.

 

Taiwan has a company launched four sections called the EZ-Dimming GM6182 switch tone light of high efficiency led lighting would be a good program. Only the use of ordinary light switch on the wall will be able to achieve the dimming, the first time open for all light, the second on 60% brightness, third on 40% brightness, the fourth open for 20% brightness. The advantage of this system can use an ordinary wall switch dimming. And the power factor more than 0.92. Did not produce interfering signals into account. The disadvantage cannot be continuous dimming. There are operational high efficiency led lighting problems.
