merger and acquisition are the first market and customer for leds

Liu Jianyun thinks, M & A itself is composed of two parts.The first part is the mergers value  of LED company , the second part is the transaction value.Namely: good acquisition value plus  reasonable transaction structure. The value of mergers is the acquisitions market and customers, the enterprise market and customer has significance for the acquirer.

Both the Formosa Epitaxy and Sanan ,or Huga and Epistar, or Lunda and power fierce, is not difficult to find, cooperation and integration between enterprises to occupy more market that is the important starting point of each enterprise for whatever reason.

M & A value is the first market and customer for leds

Chairman of Formosa Epitaxy Optical Co., Ltd. Jane said in July this year,  I hope to explore the mainland market for lighting system vendors can in-depth cooperation in mainland about  future lighting market Next focus of Epitaxy .We choose to cooperat with Sanan finally, Canyuan pay more attention to broad market and government support for the LED industry mainland that Sanan had . As Jane Feng Ren said, Sanan Lighting have optoelectronic three large capacity, low cost price to the future cooperation between the two sides, the cost can be reduced.Also let Canyuan Lighting successfully entered the mainland market.Sanan Lighting can  enter into the overseas market through the Cuiyuan photoelectric international channels to create a win-win.

Chairman of Ronda electronic  Su Fengzheng said, Welly-power in LEDs package SMT ( surface mount ) process, Strip, lighting and other customers can bring new customers for the Ronda, the complementarity of the two sides is quite strong, can increase the Lunda customers in non AUO.

Lunda electronics as the only leds manufacturers  with ” on the middle and lower reaches of the through-train mode ” production in Taiwan , has a rich experience in the industry integration. Su Fengzheng Said in procedure of acceptation the Chinese semiconductor lighting network interview in June this year, the key of vertical integration effect appeared is to have a broad end market , the export. Therefore, the most important one of vertical integration is to have downstream estuary.

Occuping the market share number is fundamental of enterprice existence.Merger integration can not only produce the scale effect, but also can integrate the market resources. With the help of others power easier into themselves are not familiar with the market, play a multiplier effect. The industry forward,in addition to the upward integration to improve the quality and efficiency of the production technology and reduce costs;The level of integration with the traditional lighting manufacturers both powerful pathway advantage , is also a critical business strategy.

Low-profit led work light era ” winter ” is coming

Since this year, following the vision photoelectric, eye-opening light, hibo photo-electricity and a number of billions of scale LED work light enterprises have closed down, Another hundreds of millions of corporate Jiahao light was closed down for up to 18 million yuan loan arrears suppliers .Near the end of the year, it is time for collection of payment, some funds tight chain of small and medium-sized enterprises.Under the payment due or upstream suppliers, it is very likely to have a usurious loan increase, boss run away or even bankrupt phenomenon.

Low-profit led work light era " winter " is coming

The main reason of funding strand breaks is that excess capacity , the price decline , low profits. This phenomenon not only appears in the small and medium-sized enterprises, in many LED listed company also appeared to glide considerably profit trend.

According to statistics, 25 LED key listing Corporation revenue grew 15 companies in the third quarter of this year,accounting for 60% of the total  , 10.83% lower than the first half of the year; net profit year-on-year growth of only 10, accounting for 40% of the total. 25 listing Corporation above, the decline in performance is more serious for the upstream chip and downstream enterprises display application.

According to the National Lighting R & D and Industry Alliance (CSA ) statistics, the current domestic led work light epitaxial chip enterprises is over 60 companies, the number of MOCVD equipment has been put in place about 1000 Taiwan, has become the place that have largest number of MOCVD machine. But because of , technology, personnel, patents, market demand and other reasons in the debugging process, upstream capacity has not been fully released, according to incomplete statistics.The epitaxial silicon enterprises capacity utilization ( operating rate ) is only about 50%.

M & A integration ” Use of groups ”

In this “breakout ” of the market fight , Various enterprises can be described as the ” Eight Immortals recount “. Actively open up channels and application market, IPO listed market expansion capital, go differentiation route the main market segments, make price war greatly fast landing, many enterprises choose a more direct” Groups heating ” mode, namely the merger integration.

Maybe for in which subjected to the ” market suffering ” enterprises, some suffer unspeakably. But we need to realize that, the development of an industry, especially in emerging industries, take into account the law of industry development, and sober look at the problem.The g24 LED industry only went through full competition and then just can achieve the merger and reorganization, the survival of the fittest. As the combined force of Qingyuan venture President Liu Jianyun said, M & A is just a tool that often occur in the growth stage.and increasingly fierce industry resource matching process.M & A is a normal phenomenon.

The globalization competition increased the bursting of full LED World War

We expected that in 2015 the global LED lighting market is expected to reach $ 21.7 billion. With the process of city urbanization that countries have banned the production of incandescent lamps, and the curtain opened that the global LED lighting to replace incandescent, the LED lighting market prospects are promising. In the competitive situation of economic globalization, the global full led industry is also deeply feel to integrate specifications, standardized and unified standard imperative. However, under these existing or to be developed standard, who have the authority, professionalism, versatility and enough potential to dominate the world, and become truly international generic standard?

The globalization competition increased the bursting of full LED World War

Europe, the U.S. and Japan and South Korea and other countries have introduced policies to support the development of LED lighting products industry. The one who holds the international giant LED core technology, is located under the strict patent barriers. The International Commission on Illumination, International Electromechanical Commission, the light engine of the Council of Europe, the U.S. Energy Standard and other industry organizations have also set up their own LED lighting products standards to define the rules of the game.

In an Opportune time, integration of Guangdong full led industry quality resources, standards vacancy to fill the domestic standardization light assembly and lamps, LED application product versatility, compatibility the LED standard optical components came into being, and the Science and Technology Department of Guangdong Province, the National lighting R & D and Industry Alliance guidance, and semiconductor lighting industry in Guangdong Province, organization and implementation of joint innovation center, and fail to bear fruits, to promote the health of China’s LED industry booming, one of the world’s forefront of LED industry laid the foundation. LED standard optical components for its authoritative, professional and practical, step-by-step to the world standard by Chinese standards, and achieve the transition from Made in China to the Chinese wisdom made.

The globalization competition increased, so the full led World War burst

The War of the LED industry began many years ago, just the parties are eating away at the preparation stage, but the conflict is not obvious. But this year, LED compete smoke everywhere, the price war broke out, and subsequent channels warfare surfaced. Throughout the development of the global LED industry, the outbreak of the War of the Worlds, industrial pattern will also face reconstruction.

led smd and led heat sink

Using LED high bay brightness lighting requirements using manufacturers allow maximum current drive, but the average life expectancy of LEDs is highly dependent on temperature. Operating temperature rose by only 10 ° C can make life shortened by half. This situation forced designers to adjust the current must be reduced, sacrificing brightness to extend the service life. If required LED working under high ambient temperatures, the need to further reduce the current to minimize the environment to the chip temperature rise, in order to ensure the service life. However, due to the presence of the upper temperature limit, this will reduce the brightness of the illumination of the medium and low ambient temperature range. Essentially by lowering the brightness to achieve the work of high-temperature environments led smd.

LED array current is adjusted by the voltage of the detected current detection resistor R7, and is used as a feedback control of the controller, for example: TPS40211. The operational amplifier circuit (R9), to inject a current to the feedback node (FB) regulating current in order to reduce, or to increase the regulation current pour its current. FB node voltage is kept constant 0.26V. R7 voltage must be reduced to improve the voltage of the op-amp output (TP1), to obtain the compensation, so as to reduce the LED current. When the operational amplifier output just as 0.26V, the injection current is zero, while the LED adjustment will not be affected.

led smd and led heat sink

 

Thermistor RT1 is a negative temperature coefficient (NTC) devices. 25 ℃ It has a nominal resistance of 10K ohms, but the increase at -40 ℃ to 300K ohms or more, and at 100 ℃ are reduced to less than 1K ohm, and is in a nonlinear way. Resistors R8 and R10 5V bias voltage close FB voltage reduction, the value of R9 is to control the speed of the current reduced with the high temperature variations. The use of better adjusting the bias voltage is very important, because the accuracy of the circuit is subject to the influence of the bias tolerance. Resistors R9 must be placed as close to the current mode boost controllers placed, the purpose is to minimize the noise sensitivity. Use thermal epoxy the thermistor RT1 as close as possible to the central LED on the PWB connection led smd.

Only LED and thermistor in this temperature range. The thermistor detects the temperature is plotted as a graph, compared with the ambient temperature. We will calculate the obtained LED chip temperature is also plotted, which is equal to the temperature of the circuit board coupled to each LED of the power multiplied by the junction to the chassis (8 ° C / W) Thermal impedance. We can see that under high ambient temperature conditions, the operational amplifier circuit to reduce the LED current, the LED chip temperature close to the temperature of the LED circuit board. In this case, the temperature of the LED circuit board close to the ambient temperature, since the LED current is almost zero. This can be achieved LED chip temperature stability did not change. The RT1 nonlinear highest temperature LED current rapidly changing. The TP1 temperature “control voltage” also been drawn into the diagram, and well matched with the expected value led smd.
