LED landscape lights: combine popularization with the raising of standards

 

In related news was informed that from March 1, Guangdong Province, all financial investment in new lighting projects and new planning and development of the region field of public lighting, all LED lighting products. Three-year period of universal public lighting, including the Pearl River Delta two years time. Involved in financial-funded construction projects in the public domain, any use of LED lighting, this work should be completed in 2014. Requirements since March 1 this year, all financial investment in Guangdong Province, the new lighting project and new planning and development of the region field of public lighting, all LED landscape lights. Cities (including Shenzhen) required in the April 1 popularity of LED lighting products, the overall objectives and schedule development of the region.

 

However, regardless of the final lighting products, companies are a good opportunity for the entire LED lighting industry. Skyworth, TCL, Konka and other Chinese mainland traditional home appliance makers, competing recently branched out into the light emitting diode (LED) lighting market, with strong capital, strong brand channel and vertical integration planning, market strategy, moving rapidly encroaching incurred in mainland China LED landscape lights market and intensifying competition, Shenzhen Sheng Hao Group to further strengthen the R & D of LED lighting products, the product well and stronger, for small and medium-sized range of LED supply chain industry will face great survival test .

 

Generally speaking, many enterprises of the project competition for the big cake, the Chinese mainland home appliance manufacturers to rely on a huge enterprise-wide, brand, channel and control key upstream components, advantages, and a big way to enter the led high bay lighting market, the rapid tightening of small and medium range LED chip, living space of the package with the LED lighting business.

The promotion of solar powered led street lights still needs to be improved

 

The promotion of solar powered led street lights still needs to be improved

 

The growing popularity of LED lighting, LED display. Implementation of the results of the most significant national undeniable Japan Asia LED lighting, LED bulb is on the market share in Japan’s largest lighting. In this respect China is far less than Japan.

 

From the results of Japan to promote solar powered led street lights, in addition to 311 large earthquakes in Japan so that they further enhance the outside of the awareness of environmental protection and energy saving. More important is that Japan has developed LED lighting, security, performance and interchangeability specifications, and more to ensure the interests of consumers, to ensure the quality of the product. Manufacturers in the manufacturing method to follow, within a certain range to reduce the production of shoddy products.

 

The current solar powered led street lights standards in Japan, Japan Industrial Standard JIS and the JEL Japanese electric ball industry specifications two categories.  mainly the LED lighting module and power dome LED lamp safety specifications and performance requirements of these standards LED lighting in a variety of environments, security, and color rendition, brightness, life, exclude security and performance below the specification of LED lighting products, in order to completely replace the traditional incandescent light bulbs and other lighting goal. The LED lighting is currently no national standards, only local governments to formulate their own specifications requirements.

 

The electric ball industry in Japan will develop LED lighting specifications, there are four main define the form of LED lighting and marking, as well as LED lighting and traditional lighting of the mouth of gold and system compatibility. Unlike traditional led high bay lights in the weight, circuit, system requirements Dengjun, if not to develop the interoperability specification, could easily lead to damage of the LED lighting when in use, even heat, fire, and dangerous.

The household led light bulbs is required to shuffle the card

 

The household led light bulbs is required to shuffle the card

 

In the LED industry, many people in the Scream LED industry will reshuffle. Shuffling personal opinion is not the most important issue, the question is what the problem is caused by the shuffle.

 

Shenzhen is the country’s largest LED display manufacturing and supply base, LED backlight, household led light bulbs are the world’s largest production and supply base. About 3200 LED enterprises account for 40 percent of the country. Many people believe that enterprises in Shenzhen this year will be reduced by 20% -30% means that nearly a thousand LED business in the economic winter “dead” to go. More pessimistic predictions, currently nearly 8000 LED Enterprises “when the reshuffle of the industry as a whole, the country remaining 300 enterprises would be sufficient.”

 

Higher elimination rate of the household led light bulbs industry, entering large state-owned enterprises, small enterprises due to the competitive relationship in the exit. LED enterprises in Shenzhen this year will be reduced, means that nearly a thousand LED business in the economic winter “dead” to.

 

Although pessimistic about the development of the industry, but only the appropriate market enterprises to survive, the enterprise market-oriented. Excessive development of led high bay lighting industry, there are a lot of problems, shuffling to the unqualified enterprises eliminated, in order to allow the market to better health. More conducive to long-term development of the LED industry, but only 300 would be too cruel results.

 

Chinese government call on an Industrialization restructuring of household led light bulbs industry. There is no other choice, after China’s accession to the WTO2006, many industries needs with the international practice, including LED lighting industry.

 

Three reasons for the continuous slump in RGB led downlight market

 

Three reasons for the continuous slump in RGB led downlight market

 

The reason to come to this prediction can be summarized as the following three points:

1: the shortage of domestic talent, the country’s strong support as a sunrise industry, LED industry, the domestic enterprises herd redundant construction, not only talent ‘poaching’ phenomenon prominent; some accumulation of capital to make RGB led downlight after a sale to influence the market; more the enterprise is purely to defraud the government holding the LED of the first support funds. ”

2: The threshold is too low, many companies do bad RGB led downlight market is definitely good for the industry, the introduction of relevant policies, but did not implement. Local government if you do not examine whether the LED business is truly master the core technology, or the existence of idle land, capital, equipment, too many enterprises to enter the industry can only do bad market! The access threshold of the government audit LED business to improve, and to moderately reduce the tax burden on the LED business. As for the funding of government subsidies, the current situation is no standard no rules, loosely organized, no one to guide the development of routes allow enterprises to fend for themselves, but the government capital subsidy standards should be re-enacted.

3 exports: in the context of the European debt crisis, this year’s overseas economic environment is not good, while exports of the main exit of the Shenzhen led high bay products. In the early years, the export of Shenzhen LED products mainly exported to up to 80% to 90%; this ratio data declined only modestly from the previous year, is currently about 80%. The poor economic environment, the export of LED products have certainly been affected, and appreciation of the yuan, also greatly reduced the profit margins of these LED business.

HV technology used in solar led street lamp

 

HV technology used in solar led street lamp

 

The HV the solar led street lamp is made ​​directly on silicon chip production system on a chip (SOPs), which is a revolutionary advancement of the LED chip manufacturing technology. A 2-inch silicon wafers, one can produce tens of thousands of LED die, but using common technologies and processes to produce discrete LED parameters. So, after the production, manufacturers need to individually measure the parameter file, the client can only take the third gear of the adjacent units (light) in order to ensure consistency of display light color. The HV LEDs in the production of a new generation of technology and superb processing technology, tens of thousands of LED die in the same silicon wafers on the parameters exactly the same so easily in chip production, the nearest composition of the SOC HV LEDs for such as the 16 LEDs on the HV45, all of their electrical parameters are exactly the same. HV LEDs for easy to use, cost control. Otherwise a COB HV LED is the adoption of the aforementioned general-purpose technology to produce the parameters of discrete led high bay chips die, will be the same configuration of the test data together, re-combined into a light body. Due to the need to individually test, matching, filtering, and combinations, there are many parameters can not be dispersed paired combination use, production costs will be high.

 

In addition to the low-voltage solar led street lamp driver chip, the domestic high-voltage LED driver chip has also emerged market, the high-voltage LED chipset high-voltage, low current, compared with the common low-voltage LED low voltage, high current working environment, when the fever HVLEDs work reduce the; HVLEDs only need a high-voltage constant-current source can be a good, high-voltage constant-current power transformer, electrolytic capacitor low-voltage LED driver power supply and electrolytic capacitor life.

How to increase the duration of high-power LED driver

 

How to increase the duration of high-power LED driver

 

Essential as power devices, electrolytic capacitors must be able to long-term work in high temperature environment, this test is very grim. General-purpose aluminum electrolytic capacitor life span of only 4000 hours to 5000 hours, half life, and at high temperatures is far from meeting the requirements of the long life of LED lighting, and thus the aluminum electrolytic capacitor has become the bottleneck of the high-power LED driver. The structural design of aluminum electrolytic capacitors, the advanced nature of the manufacturing process to determine its service life. Aluminum electrolytic capacitors for LED lighting special emphasis on long life, high temperature and small.

 

The high-voltage driver chip may be one of the better solution HVLEDs constant current drive power. Some chips are ideal, but is too expensive to buy in China, used to produce general-purpose high-power LED driver costs are high. In recent years, China’s domestic integrated circuit design level rising, but there is a very good price and market competitiveness, to downstream manufacturers for the production of technical solutions and technical support in place.

 

In addition, the LED light source lamp bead is a major breakthrough. The rising star of the LED family of high-voltage LEDs (HV LEDs) have sprung up everywhere, the VF high voltage, the IF current working conditions completely subverts the traditional low-voltage (LV LED) LED VF low voltage, the IF current requirements. Led high bay lighting due to the HV LEDs SOP may reduce the shape of the heating, lighting structure may tend to be more to save cooling materials, greater than 270 degrees light-emitting, low-cost, light weight.
