Technology trends of the led lights chip

Tony Armstrong, Linear Technology Power Products Division director of product marketing, with the further development of the LED, its effectiveness or the ability continue to improve. Secondly, LED lighting have environmental protection characteristics, which no need to deal with exposure and disposed of in a common toxic mercury vapor in the cold cathode fluorescent lamp. Finally, incandescent bulbs, and often need to be replaced after about 10000 hours. However, the led lights can provide over 100,000 hours of life. These figures are outshone.

Texas Instruments (TI) Business Development Manager Han Gan analysis, it is well known that the LED driver model high ambient temperature, and the module thermal conditions is poor, leading to the LED Panel driver circuit has been working at higher temperatures, which will lead to the reliability of the led lights applications reduce, and shorten the life of a series of questions. So the heat had to highly considered. Reliability and safety regulations is very easy to ignore and part, especially before the enforcement of relevant provisions, in order to reduce costs, part of the LED lighting manufacturers will be omitted reliability and safety circuits, but this is precisely the long-term fundamental of the led lights industry developing and also the embodiment of the design capacity of LED driver chip manufactures. Different chip manufacturers provide programs, which increase the costs vary greatly.

The accumulate Technology Co., Ltd. Product Director Yu Zhongwei think that it should be noted that the shape of the trend of standardization, such as the US Energy Star and Japan PSE specification. In addition, the dimming feature is more and more noticed. Such as the traditional SCR dimming 1-10V dimming, as well as DALI dimming. Finally, it is to address the thermal issues arising from the requirements of the driver program. In addition to cost considerations, a more lightweight requirements, but also must take into account of the better electrical characteristics(efficiency, power factor, electromagnetic interference, output ripple, etc.)

Semiconductor lighting market, technical marketing manager Lin Zhiyan said LED Tube is essentially a low-voltage devices, depending on the color and the current, its forward voltage drop may vary between 2 to 4.5 V, and it requires a constant current to drive.

The beautiful led lights effect can not afford the high cost of injury

Advances in technology, skills enhancement, car manufacturing has brought more changes. In recent years, the popular group of the led lights  give us a shine. With widely used “daytime running lights”, both beautiful “angel eyes” began to appear in the streets. When people enjoy these cool equipment that brings the visual pleasure at the same time, the problem behind also call for deep thought. Recently, the “Southern Metropolis Daily” damage replacement the led lights produced by the high cost and inconvenience, were reported. How to properly treat these problems become our focus today.

Mr. Dai of the professionals of the automotive lighting systems address this issue, put forward our point of view: auto parts manufacturing, including lighting systems, and design concept, the formation of the trend of more and more accessories difficult to replace of the entire assembly. Therefore, the supply of the spare parts on the market will be involved towards the whole plant maintenance solutions.

Compared with the old car used the traditional light bulbs, LED lamps have long life, better advantages of the lighting and more beautiful appearance. Automotive headlamps when using,  give a heat issue, leading to the surrounding temperature high, and difficult for cooling heating. The width light LED car made the normal operating temperature is below 60 ℃, when the temperature exceeds 60 ℃, the LED becomes less stable. Therefore, the biggest factor to affect the efficiency and lifetime of LED automotive lighting is the temperature. Therefore, If the headlamp of the surrounding temperature exceeds a certain temperature, the LED is very easy to burn, even sometimes the base of the LED lights will directly melt. For most of vehicles using LED lights, if the diode damage is more serious  and need to directly replace the assembly. Therefore, it is recommended to use good LED thermal conductivity. Moreover, in the use of the led lights , If not all lights do not shine, the number of fault lights affect the results of case, the entire assembly to be replaced, thus to keep maintenance costs to a minimum.

How to reduce the replacement cost of the owners? and also improve the existing LED High Bay technology is the problem facing in various car manufacturers. As customer, they should have a correct understanding and application of new technologies, not to use some improper way to safeguard their rights.

The led lights will illuminate the future

On April 2012, electronic components industry segments except for the semiconductor industry, other industries have achieved a positive return of 300, thus it became one of the highlights of the market. In many segments of the electronics industry, the most optimistic industry is no doubt that the led lights.

May 7th, the Ministry of Science and Technology issued a semiconductor lighting technology development plan. It put forward to 2015: the the led lights industry reached 500 billion yuan, accounting for 30% of the general lighting. Focus on fostering 20-30 leading enterprises, and built 20 national industry base and 50 model cities. While the market share of China’s LED lighting and LED STREET LIGHT is less than 1%, so it has huge market space for development. In the next few years, the huge potential market size of China’s LED industry usher in a period of rapid development.

At the same time, the plan pointed out that the nationalization of the Twelfth Five plan, to improve chip optical efficiency, and to reduce the cost to 1/5. LED chips accounted for about 60 percent of the estimates. The drops by 50% of the light chip can drive the lamps cost down. In addition to the upgrading of packaging technology and the popularity of cost-effective, the lighting cost can be reduced to 30-40% to replace 40W incandescent. The street decline slightly, but can also be reduced to a thousand or so the mainstream price, which is useful to accelerate the penetration.

In addition, lamps, drive technology, testing equipment and other national standard-setting, and the popularity of the EMC model will play a catalytic role for the five-second period of the led lights to open the market.

The Beijing’s bidding in March 20th, we mentioned in previous reports of 80 million round of subsidies, but the amount is not large. It is about 2 million indoor down lights spotlights in LED SPOT, tens of thousands of street lamps, the amount of only about 200 million yuan. So each company use it as their own brand name tools to give a low offer and no significant contribution to company’s performance. 110 enterprises participating in the tender, the offer of the same type of product can be a difference of more than ten times, which the traditional lighting companies offer lower tender.

Cross-border mergers and acquisitions of the led lights usher the best time

Integration is power, while mergers and acquisition the led lights are undoubtedly an effective way of integration of resources. Under the today’s economic globalization, corss-border mergers and acquistions are rapid accumulation of capital, resources. It is an important means of market expansion. On the eve of the era of LED lighting, by merging and acquisitions to enlarge the LED High Bay lighting market, which has been the consensus of the lighting professionals. International environment Chinese enterprises participated in cross-border mergers and acquisitions had pasted two decades. From  1992 to 2000, the peak of the first foreign investment began the second wave of the peak since 2000. Since China joined the WTO, Chinese enterprises to invest overseas. The first stage is a trial, mergers and acquisitions is quite small. The second phase of M & A peak after another, Chinese companies realized that only integration into the world economic system which can have a stronger ability to survive. The fist business that China export is Lenovo, TCL as the representative of consumer electronics and household electrical applicance enterprises. Followed by is the automotive industry and the financial sector started in 2006 and 2007, which is eye-catching. At the same time, oil, mining and other resource companies, also become a wave of Chinese forces in the international M&A market. But in the new round of mergers and acquisitions boom of the led lights, the scope of the object of  China mergers and acquisitions has greatly expanded, more open vision. Engineering machinery, automobiles, consumer goods, and even the luxury goods sector, are constantly heard the news of mergers and acquisitions by Chinese companies. Beginning with 201o, the lighting industry is also emerging in the list fo overseas acquisitions. NVC lighting, solar lighting, BDO Runda lighting and so on has embarked on a journey of the cross-border takeovers. In 2002, China’s mergers and acquisitions in the led lights and LED Products are only$ 200 million, in 2003, which reached to $ 834 million, an increase of more than four times, showing a rapid increase in momentum. In 2004, only Lenovo acquired IBM’s personal business amount of $ 1.75 billion. According to the estimates of the global consulting firm in Las Beckham, in  2004, China’s enterprises overseas mergers and acquisitions amounted to $ 7,000,000,000. According to Commerce Department Statistics, in 2011, China’s domestic investors were non-financial overseas direct investment aiming at 132 countries and regions around the world 3391 foreign enterprises. In terms of scale or volume terms, overseas mergers and acquisitions of Chinese enterprises grow steadily.
