But when about to enter the 21st century, the United States go back to the hegemony,LED high bay Intel is so far still occupy the top ranking, and the situation becomes more complex, theJapanese competitor is no longer a U.S., South Koreaand China Taiwan has also become a strong competitor. Japanese companies ranked from bad to worse, led strip lighting kitchen the hat ofthe world’s second-largest economy last year, China has also been picked (even if we do not fully appreciate), as a strategic industry, electronics industry, the role of the revitalization of the heavy responsibility.

Panasonic walkman, game consoles of Sony, Canon camera was an iphone played it completely, these once coveted Japanese manufactured products has slowly become adusty diary.

The future direction of the pulse of the decision of the Government for the industry

The government does not allow the enterprises in strategic industries to fend for themselves, led strip lighting kitchen the merger could be a glimpse traces of the government intervention, I believe that the Japanese government will invest more energy and attention to the development of the industry.

Japan Electronics and precision with the industry, enterprises will increase investment in materials and workmanship, SoC their future direction of development require higherprecision, is to meet the characteristics of Japanese companies.

Rely on demand-driven led lighting products market and thus to promote research and development, is the only way of any development of the industry, led strip lighting kitchen working hard at the same time will pay more attention to market development and advocacy.

The attention of the Japanese semiconductor industry is to give us some, perhaps as early as recognize, but we have lagged behind very far is not a reason to give up and could not recover, led strip lighting kitchen Samsung is able to do from the imitation of the industry’s second place, the instructions to change the IC led street light the status quo of the first large imports is not impossible.

led street lights price and temperature rise problems

led street lights price and temperature rise problems

 

During we use LED lights, we would find, the higher temperature is, the lower lumen output is, so, why is it situation a problem for led street light price?

Normally, the reasons are, Chip quality, solid crystal bottom plastic, phosphor, fluorescent glue, brackets, andcooling.

Let’s analyze the reasons from the inside structure of the led street light price and led products. All these test results are from the top LED High Bay company–ENELTEC.

Test A:

We use Nichia183 LED, no heat sink, link it in the circuit, put the soldering iron on the foot of led. If the temperature is not very high, the lumen output of led would be lower, when the temperature  reach 380℃, the led would stop working at once. Now, then voltage of led would be lower than 1 V, but the PN is still good, it means the led is not dead. Then, if you low down the temperature of  soldering iron, the lumen output would me higher.

Test B:

We use 3528 white LED, put the soldering iron to make the hot, 260℃ and 290℃. Heat them by 260℃ for 1 minute, and then test the lumen after it’s cool.  Then heat them by 290℃ for 1 minute,  and then test the lumen after it’s cool.

We tested 5 pcs of LED, the 260℃ for 1 minute, the lumen is not lower, but even higher!  Please check the data listed below.

 

 No.

Now, let’s analyze the results.

From test A, in the high temperature, the lumen get lower, even stop working, when the temperature get lower, the lumen would be back to normal.

From test B, After the high temperature, the lumen is even higher, so, the lumen get lower only by long time high temperature working. So, we should do the correct design and calculate the led street lights price.

 

China’s mr16 light fittings industry development towards regionalization and grouping

China's mr16 light fittings industry development towards regionalization and grouping

China is the world’s most important consumer electronics and lighting products production base, making it the world’s largest LED street light components application market, the 2011 global consumption of about 35% of the LED components. LED Lighting China Market Application to the public landscape lighting, electronic products, backlight, mr16 light fittings, screen / billboard, general lighting for the four major application areas. China’s LED industry is moving towards regionalization and the direction of the Group.

The lighting industry is basically there is the light of globalization, the characteristics of the lamps in the localization industry. Together with recent years the Chinese LED market opportunities, mr16 light fittings, mainly from government public construction and demonstration of tenders, the proportion of residential and commercial and industrial lighting, indoor lighting market is still low, that mainland China’s LED lighting industry and gradually formed a special regionalized group strategic layout.

Although China is a unitary leadership system, but local governments in the economic and industrial development, in fact, highly competitive, LED lighting at the same time have a huge market potential and the characteristics of the energy industry, led high bay more local government areas of battleground. Particularly in the coastal provinces and cities more economic strength, such as Guangdong, Zhejiang, Jiangsu and the fostering and protection of the local LED lighting manufacturers spare no effort. In the thinking of local governments to foster the development of local industries, mr16 light fittings, market protection measures significantly, if the failure to obtain the support of local government, LED lighting manufacturers will be difficult to market distribution across provinces, making mainland China LED lighting manufacturer with a significant local color, and gradually form regionalized powers separatist race condition.

China LED lighting industry funds and technology into the low barriers to supply chain management costs, coupled with the market regionalization characteristics of the firms invariably take vertically integrated strategic layout, making mainland China LED lighting industry is gradually emerging from the past identified mold, low quality the outlook of the industry, mr16 light fittings, the formation of a large group of industrial competition

Identify how to purchase led lights in good quality with 3 points

Identify how to purchase led lights in good quality with 3 points

With the continuous development of society, the LED lights with the lighting of the city can replace the neon lights, play an important role, purchase led lights, while LED lights with the production of many people entered the low-threshold, launched this project. But those with experience have a way to identify the regular manufacturers to produce LED lights and LED lights of the cottage version of the band (ie depends on manual work products produced in the rental) is a glance from the appearance of out. LED high bay The following talk about with eyes to identify the LED lights with the quality of good or bad:

1, see the solder joints. Regular LED lights with manufacturers to produce LED lights with SMT chip technology, purchase led lights, the production of solder paste and reflow soldering processes. Therefore, the LED lights to bring the solder joint is relatively smooth and the amount of solder will not solder cylindrical arc-shaped LED electrode extends from the FPC pad to. Cottage version of LED lights with solder joints is uneven, mostly a dot wrap welding foot, and have varying degrees of tin tip, which is a typical phenomenon of manual welding.

2, see FPC quality. FPC sub copper and rolled copper two Bonded Copper copper foil is projecting the look of the words from the pad to be seen with the FPC connections.Rolled copper is close and FPC as a single entity, purchase led lights, can be bent without the pad off phenomenon. Bonded Copper bending too much there will be pads off, the temperature is too high maintenance, can also cause the pad off.

3, see the LED light with the surface cleanliness. If the SMT production, LED lights, the cleanliness of its surface is very good, purchase led lights, do not see any impurities and stains. But if the cottage version of LED lights with the production of hand-welding process, the surface no matter how clean, will be residual traces of stains and cleaning the surface of the FPC will be flux and tin slag residue.

2012 supermarket white led light has been predicted, and summed up the following three features

2012 supermarket white led light has been predicted, and summed up the following three features

First, the foreign large supermarket chains still T5-based LED products, try to gradually extend. Late last year, LED lighting products have been 100 Wal-Mart in China. Theapplication of LED lighting products, not only to Wal-Mart 50% of lighting electricitysavings, white led light but also help Wal-Mart’s environmental protection and energy saving.

Second, the supermarket lighting market is highly competitive. May white led light encounter a”personal overtaking in a fully competitive lighting market environment, a little slack.

Third, LED products, high barriers to entry, foreign supermarket only value the quality of the product, and not really care about the price. This virtually set an entry barrier, LED high bay only LED companies win low price but high quality technology to block the door.

At the same time, Lin Xiaojia noted with concern that “In recent years the development ofthe LED light source has been developed into the darling of the lighting business, white led light but it is undeniable that most of the core technology and profit are foreign lighting giant carved up by the traditional domestic lighting basic easy assembly of the main, almost ‘not behind’situation. ”

LED promotion of seeking breakthroughs supermarket lighting shall be considered

At present, the ambient lighting of supermarkets and shopping malls lamps and light sources, white led light including CFL downlights and T5/T8 fluorescent lamp bracket grille and metal halide. The general lighting of the supermarkets more and more inclined straight tube fluorescent lamps to the three primary colors primary light source, and using low-power, white led light high power factor and stable performance of electronic ballast, or the new breed ofballasts.

Cast optimistic views to supply high power led street light

Cast optimistic views to supply high power led street light

Looking forward to 2012, the LED people industry are still optimistic about supply high power led street light in China’s LED lighting market.

Looing back to the past of 2011, the LED industry can be described as weird smells, the small and medium sized enterprises were difficult to move, the products were mixed, companies had flocked listed, the western industrial as a new force suddenly rises. Looking to 2012, the LED industry insiders still looking further to supply high power led street light in LED lighting market.

In 2011, the state of development of the LED device market performance in different areas of application are keeping the same. On the aspect of TV, the display backlight and LED display by the global economic impact of demand show a obvious decline. In general lighting, althought there is no explosive growth, overall, it still shows a growing tendency although it has a little gap between magnitude and speed of the expectations. Take street light as an example, compared 2011 with 2010, the installation of LED street lamp has increased 30% estimately.  Looking forward to 2012, as for general LED application field, with the steadly ingrading of light quality and effect, deduction of system cost and the implementation of encourageing policies, the situation should not be a big change and appear an increasing trend of supplying high power led street light.

As for Chinese market in recent years, LED terms are frequently mentioned. With the increase pressure of energy conservation,  China government stepped up efforts to support LED high bay. It goes without saying that China and Asia in the future will be the LED industry especially the huge market of LED lighting. But compared with developed country, China LED industry is still in its infancy. It needs not only government’s support, but also some positive policies.
