The tachycardia for led road lighting

 

The tachycardia for led road lighting

 

Output value is the current led road lighting in the domestic lighting market penetration of only 5%, core technologies rely on imports, and higher overall cost to become a stumbling block to hinder the further development of LED industry. “LED Engineering Research Institute, Dr. Xiao-Fei Zhang said.

 

LED chip is like a car engine. The lack of core technology will directly restricts the development of this industry. “Zhuang Shenan said. It is understood that the led road lighting upstream chip production technology lies in the hands of foreign companies, the slower the process of domestic technology, affecting the development of the industry. MOCVD epitaxial furnace and its related technology is the most high-end of the LED industry chain mainly dependent on imports, greatly restricted the cost control of the LED industry upstream.

 

“The overall level, the gap between China and the international first-class level, there is still about two years.” Feng-Yi Jiang believes that “in many developed and developing countries or regions in the world in accelerating the development of the semiconductor lighting technology and industry, technology , China in the second echelon.

 

Blind investment and lack of core technology makes led high bay lighting market in China was mixed, good and bad. Unstable quality is also a LED enterprises generally faced with a problem. “Some customers a higher price to go back to the LED lights, and even thousands of hours not last, and even the quality is not as good as traditional lighting led road lighting market, there are many small and medium enterprises for the production of low-quality products, the industry pattern of instability.” Zhuang Shenan said.

 

Spring for led yard lighting

While led yard lighting industry to usher in the spring tide like the rapid development of, a lot of controversy on its overheated investment emerged. Some even thought that in the domestic market has not really started, the fanaticism development will overextend the future production capacity and market. Is the prospect of unlimited or difficult, the led yard lighting industry in China is exactly What are the opportunities and challenges.

 

LED lighting industry overheated investment

 

Currently, China has semiconductor led yard lighting included in the medium-and long-term technology development plan, has now formed a production of epitaxial wafers, chip preparation, packaging integrated industrial chain of LED applications. Good policy, the domestic LED industry, the rapid development of a potential blowout.

 

Nanchang University Vice President Feng-Yi Jiang, since last year, the led yard lighting industry began to trot to the development of the situation from upstream to downstream, in the first half of the year blowout state. According to statistics, in 2009, China’s led high bay industry, the upstream firm has nearly 60, the middle reaches of the device packaging companies have more than 1,000, more than 2,000 enterprises of downstream applications, employed more than 80 million people. Middle and lower reaches of the semiconductor lighting industry output value of 82.7 billion yuan in 2009.

 

Spring frenzy of investment in LED lighting industry exposure defects

 

The report shows that now, led yard lighting has gone beyond the backlight LED market, the fastest growing application market. By 2015, the LED output value of penetration in the domestic lighting market will reach 1/4.

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. “

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.
