Quanzhou: mains LED lighting industry begin to take shape

 

The Quanzhou LED display manufacturers, about 30, but not be overlooked is the lack of core technology, but in giving to do the processing, low value-added products, coupled with the corporate homogenization of low-price competition may cause The Quanzhou reduced to the processing base of the mains LED lighting industry. “Independent core technology R & D is not realistic for most enterprises, joint university researchers may be a shortcut to breakthroughs in core technologies shackles.” Faced with the questions of reporters how to break the low value-added, Quanzhou LED industry technology innovation strategic alliance chairman of the Yellow Water Bridge So to answer.

 

“Only the domestic market, few exports,” the situation is stabilized and

Quanzhou “export market” status is very consistent, even though the the Quanzhou LED industry has begun to take shape, but in fact close to the the Quanzhou mains LED lighting products is basically domestic-based, truly out of the country less and less.

 

So how do you find the “export” to the foreign market?, Quanzhou LED business has come out of the first step: targeting the artistic design of the lantern hot commodity abroad, some companies will be solar and led high bay lamps combine, the “selling point” gained great favor of foreign buyers. In fact, in 2007, Fujian Province, introduced to support the LED and solar photovoltaic industry related policies, Quanzhou government in recent years is also to promote energy-efficient lighting, these weathervane will make the the Quanzhou LED industry has entered a phase of rapid development, by This export channel to get through. Quanzhou Solar LED lights are mainly exported to the U.S., EU, Japan, Canada and other countries.

Review the financial subsidy policy for LED street lighting

 

Review the financial subsidy policy for LED street lighting

 

Wu H: LED street lighting promotion should not be a big way, financial subsidies should be the first pilot, launched a demonstration case and then be assessed to prevent the big investment income is small. In addition, successful enterprises if they can not overcome the technical difficulties to produce excellent quality products, will also highlight its weaknesses, in this project have a negative impact.

 

Full health: the government standards for public bidding of the LED street lighting financial subsidies may be based on information developed, this standard is appropriate to use practice to test. The end user should be thousands of families, and indoor lighting can really spread to millions of households, the same need to practice to prove.

 

Liu Jun: LED street lighting and led high bay lighting, only five companies were selected, the competition can be fierce, LED lighting brands are the Eight Immortals, have done their best to find ways to win the qualifying for. Although uncertain, the subsidies to the specific number and amount of strategic significance may be greater than the actual profit gains, improved the performance of listed companies in the secondary market will gain more favor. There is also an Aspect is worth noting that the NVC and Zhejiang Sunshine, represented by the traditional lighting companies in the ground, within the sphere of influence of Chau, crystal and LED lighting companies to achieve a breakthrough.

 

Li Xuliang: This means that the semiconductor (LED street lighting) lighting industry will usher in a new round of favorable policies. The overseas market has been explosive growth, the floor of the subsidy policy will further stimulate the Chinese market is expected to continue high growth in the next 3-5 years. With this subsidy, the cost of the product will be further improved and will further boost consumer demand. Ground on the photoelectric will undoubtedly benefit from this policy.

Household led lights industry: market tide is coming


Household led lights industry: market tide is coming

 

When the arrival of the tide of the LED lighting, household led lights industry has not only been the National Development and Reform Commission, the attention and support of local government leaders, but also by the real estate of all ages.

 

It is understood that, Shijiazhuang East Asian real estate to the strategic vision eyes locked LED lighting and energy saving industry, entered into a collaboration with the Hebei, a well-known brand of influential LED intelligent lighting, the official capital injection to join China Wei Kaide. This cooperation has extraordinary historical significance, from the In order to implement the instructions of Premier Wen Jiabao’s emissions-reduction targets, the small side in order to meet the era of intelligent household led lights industry blowout.

 

As a real line interviews of supply and demand, the main characters must cannot little. Activities will then invite 20 to supplier covers led high bay chips of extension, LED packaging devices, LED lighting lamps, display and related parts field; 20 home buyers include LED lamps manufacture enterprise application, household led lights engineering design and construction enterprise, etc. A total of 40 of companies of procurement, sales director gather, brewing an enterprise purchase large single! Here, suppliers will listen carefully to your purchasing demand, buyers will be watching carefully more you bring the sample, a clap a match, the trade is so simple!

 

As both sides will purchase docking bridge, by using line display and meet line way, directional promotion, multiple cover, urged LED directly between enterprise and the rapid cooperation. As long as both the supply and the demand will, qiang household led lights nets will always be happy to come. Our sincerity may you see, immediately qiang LED nets enrolled in land!

 

Multiple choices for LED household protection circuit

 

Multiple choices for LED household protection circuit

 

We can choose to use transient voltage suppression diode (referred to as LED household protection circuit). Transient voltage suppression diode is a diode in the form of high-performance protection device. When its poles by the reverse transient high-energy impact, the negative 12 power of 10 seconds of a very short time speed, so that between the poles of the high impedance immediately reduced to the low resistance to absorb up to several kilowatts power surge between the poles of the voltage clamp at a predetermined voltage value, the effective protection of the precision components in LED household protection circuit. Transient voltage suppression diode has the advantages of fast response time, the transient power, low leakage current, breakdown voltage deviation of consistency, the clamping voltage is easier to control without damage to the limit of small size.

 

But in actual use is not very satisfactory. The first is to find very easy to meet the requirements of the voltage value of the TVS device. TVS devices are mainly u LED household protection circuit  and led high bay lights of the supply voltage is 24V or 12V, this voltage for normal LED lighting products is rarely finished, the test is not good. At the same time, we know: the LED light bead damage is caused because the current ambassador chip internal overheating. LED household protection circuit can only detect over-voltage can not detect over-current. Overvoltage, over current, but to select the appropriate voltage protection point difficult to grasp, this device will not be able to produce it is difficult to use in practice.

Hangzhou Lantern Festival: outdoor led landscape lighting show extraordinary talents

 

Hangzhou Lantern Festival: outdoor led landscape lighting show extraordinary talents

 

Hangzhou Arts and Crafts master teacher Cheng Di Shen, a wonderful beginning of the story, tell us a lot about the history of the Lantern.

 

The annual Lantern Festival, we have the lantern to see everyone knows, the illuminations from the Western Han Dynasty, there, dating back 2000 years of history. Real lanterns from the Emperor Ling of Han to the Tang Dynasty more lively.

 

Hangzhou Lantern reportedly originated in the Qin Dynasty. According to legend, in the Western Han Dynasty, the first in Hangzhou will be New Year’s “Tenth Five” called the Lantern Festival, Hangzhou people in this day and all lighting, which is the Lantern Festival known as the “Festival of Lights” or “Lantern Festival” reason. According to historical records, the Southern Song Dynasty Lantern Festival night, the the Kyoto Lin’an (Hangzhou) days of Street north and south, Phoenix mountain, and everyone lights, colored illuminations bucket Yan Zhenghui, stretching dozens of years without a break. Outdoor led landscape lighting put the lights, this time in Hangzhou, developed to its peak, bar lights, game lamps, lanterns become a common practice. At that time, the lights of Beijing tribute goods, white jade light, Fuzhou, Anhui the Xin’an glass lamp Jiangsu Nanjing folder Shadeng, the Changzhou material filament lamp, Suzhou Lo Kam lamps, Hangzhou sheepskin lamps and Kip Stone eye Lo lamps, etc..

 

Cheng teacher gave us a show he produced a outdoor led landscape lighting revolving door. A revolving door of points inside and outside of two parts, which have a light bulb, it will turn is the principle of the use of air heating, hot led high bay lights. Containing scientific and technological principles of the old lantern, magic bar.

 

Later, we learn to follow the process teacher lantern. See the light of the watermelon I do good?

How to improve the industry of led picture lighting

 

How to improve the industry of led picture lighting

 

Although market expectations are so high, but at this stage, due to the blind development of led picture lighting industry in China has exposed the lack of core technology, lack of innovative capacity, such as disorderly market competition.

 

“The world’s largest lighting manufacturer Philips has predicted that 90% of the 10 years of production lighting LEDs, where opportunities are huge growing market demand will drive rapid advances in technology, but the state support the led picture lighting will the lighting industry icing on the cake. As technology continues to improve, LED production costs decreased by 30% a year. The industry believes that the total phase-out of incandescent lamp not more than 10 years.

 

For the healthy and orderly development of the LED lighting industry, many experts recommend, to strengthen national overall led picture lighting industry of the local planning guidance, as soon as possible enforceable national industry standards, especially related products in the industry standard in the demonstration project, such as street lamps, tunnel lights, display, landscape lights, so that local government procurement and enterprise products are criteria to guide.

 

Many experts believe that the market becoming more competitive, strengthen the next generation of semiconductor lighting technology research and development work without delay. At the same time, the early realization of the localization of the core equipment of led high bay semiconductor lighting, high-end equipment to fundamentally change the situation in person, and to promote rapid, healthy and sustainable development of the emerging strategic industries of the Chinese semiconductor lighting. As soon as possible supporting policies to strengthen the establishment and specification of the testing organization, to avoid some do not meet the actual test results, and improve the overall level of detection and credibility.
