Not blindly follow the trend of the main color led lighting, We propose waterproof power

Waterproof performance is one of the basic requirements for the outdoor lights instead of color led lighting in LED PRODUCTS. Its quality will directly affect the long-term reliability of the LED drive power. To make good LED waterproof power supply is one of the key tasks. Lai G stressed out the importance of waterproof performance. Right now, the power demand for high-power-driven electrical is generally between 100W-200W, and due to the heat capacity of the large power supply, so it propose higher requirement for the power conversion efficiency. Lai G said, we use of LLC harmonic seismic design, the power efficiency up to 93%, and power factor above to 0.97. In addition, in the next, they will continue to increase cooperation with large companies efforts to integrate resources, and promote the development of the market. Lai G disclose, according to the needs of the market this year, Guangzhou International Lighting Exhibition, on one hand, to show the traditional large current of a single set of Low Voltage LED waterproof power supply rather than  color led lighting or LED STREET LIGHT, on another hand, to focus on introduction of low-voltage multi-channel output the voltage, low current LED waterproof drive power. According to its introduction, the low-voltage multi-output will separates 2-way to 4-way, the power voltage is from 80W-150W and 24V-52V. The high-voltage low –current LED waterproof power supply will between 100V-300V and 80W-200W to cover. In the past 17 years, the power for the electronics has been the main switching power. The products cover computer power supply. More than 10 years of intensive study, we have accumulated a wealth of technology and production experience in the field of switching power supply. This is also a force for the electronic to attack LED drive power. Faced with the industry of mass transferred to the interior lighting power for the electronics, who will not tempted to? Lai G tell to reporter that we were also concerned about the development of indoor lighting except color led lighting. The traditional G10,E27, PAR20, T8 and other small power drive also have a mature design products just like ENELTEC LED DOWN LIGHT. However, at present, LED lightings power supply still exist some problems. But compared to the previous two years ago, it had been risen to a higher level.

types of led bulbs in LED Signal Lights

With the wide application of LED Lights in our lives, the more traffic lights, railway signals, electronic equipment signal lights are high power rates, using high power LED sources. High Power, as the name meaning,  heat generated is much larger than ordinary LEDs, which is much brighter. High-power LED used in the signal light has very strict requirements, can not just ordinary LED for the LED lights, different types of led bulbs. For the following reasons:An ordinary LED general use epoxy resin as a mounting plate, high-power LED aluminum circuit boards (MCPCB).Ordinary LED using the wave soldering machine or manual welding can be high-power LED SMD welder, it’s very important for LED products types of led bulbs in LED Signal Lights High-power LED chip technology, highly integrated electronic components, the lightboard and power supply are all done very little, while the ordinary LED and its supporting components are difficult to achieve. Although the ordinary LED power is small, single LED, low fever, but its heat resistance and thermal effects are poor, while the high-power LED in all types of led bulbs is relatively concentrated, but also use chip technology installed in the aluminum panel, so you can easily design some of theradiator. Relatively normal LED glow, high-power LED in all types of led bulbs is relatively concentrated in the light distribution approximately as a concentrated light source, to avoid dark spots caused due to dead lights; high-power LED service life is longer and to better use as a concentrated light source. In summary, high-power LED High Bay lights in the universal application or due to the number of tubes, less slip, easy to use slip constant current power supply, to ensure that each LED has the same power supply. Even if individual failure will not affect the other LED supply current; and the cooling effect of high-power LED junction temperature will be relatively lower, so life will be extended; a bit more important, high-power LED allows the operating current of more than 10 times of general LED current control fluctuations in a few milliamps (ma), and will not impact on the high-power LED, but relatively common LED products, but may cause damage to the phenomenon, caution.

To speed up new led lighting have to learn from Japan

As we all know, the Japanese new led lighting market grow rapidly , mainly because the Japanese government played a very important role in the process of promoting their own development of LED industry , the strong style of the Japanese Government become a major promoter of the market pulled. From promotion LED standards to Set up, incentives the use of LED products by tax , the Japanese government actively take a series of measures to expand the new led lighting market , and set a target that achieve 100% mobile penetration rate and a 2020 high- efficiency next-generation lighting, and 2011 bulb LED lamp standard, straight tube LED lamp standards have been launched, and also enable manufacturers to have rules to follow in the product specifications . Especially the government implement the subsidies of energy-saving household appliances environmental point is the other big driver of LED street light bulb replacement demand; to stimulate domestic market demand, the Japanese government began to implement energy-saving appliances subsidy program “Eco – Point ” system in May 2009, the so-called Eco -Point system is mainly based on national burden make equivalent to 50 % cost of the product price restore to consumers, consumers can earn points to exchange other products , LED lighting products become the second batch of products approved subsidies object after the flat-panel TVs , refrigerators and air conditioning, the new led lightingshare rapidly by means of this in Japan .

According to the Forecasts of Japanese giant Toshiba , high-speed growth period of the LED lighting is in  2011 and 2012 ,the Japanese market for LED lighting turnover will be high growth and rising in the future and the LED projects. Japanese market research firm Fuji economy has recently announced the findings of the energy demand of office buildings and commercial facilities , such as LED lighting as an example of Japan , show that  Japanese stores of LED lighting market will increase by 2.8 times in 2012 , at the same time Japan  start to require lighting manufacturers to stop manufacturing , sales of incandescent light bulbs in 2012 ,the demand of the LED bulb is expected to increase ,according to the Japanese market research unit estimated  the new led lighting market penetration will reach nearly 75 % in 2015.

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.

led lighting product should be prepared well for going out

Japan is a country of relatively strict control standards of the imported products. Formerly, when Japanese businessmen imported a led lighting product and LED projects, they have to repeatedly examine a few months, especially in the details of excellence. And now, the market demand is on the top list. Some customer’s requirement is to supply as soon as possible. Except the civil LED bulb lamp, tube lamp are demanded for a lot in shopping malls, supermarkets and other units. “A deep LED lighting business person who is in charge of Japan’s export business said to reporter on the phone. According to his estimates, orders from Japan in 2-11 was only 5 to 5 times than all the orders in the previous year. At the same time, he believes that compared to Japan, China enterprises to some extent have the advantage of labor cost, but the strict quality management system is essential. “If you products export to Japan, the sense of quality should be strong. If the quality is not good, the products can not be approved. Because the quality requirements of Japanese want to make 100 points. We can say that it is the most strictly led lighting products in the world. They are usually requiring 100% appearance, safety, functional inspection to ensure quality. Once one of the Japan’s guest asked us whether we have High Bay or Street Light. We told them that we are doing high bay and street light. They said he purchased some Chinese high bay, but the failure rate is 1/3, so he mentioned the quality of domestic high bay needs to be improved. In addition to strengthen the quality of management, and how to better understand the characteristics of market demand is also critical to develop the Japanese market. A marketing director introduced, we will meet the needs of market regardless of different region, people’s preferences. For example, in Japan, we push low wattage, as it is quite LED Street light. But United States is different. They prefer wattage like 12W, and it must be warm. In addition, we developed a lot of intelligent application of technology, such as intelligent lighting. Using I pad, I phone to control all the lights. When you come at home, all the lights will be open.

Japan, Korea, mainland China and Taiwan how to fight cost of led bulbs

2012, for the LED high bay lights industry, cross-border, price war, patent battle, the channel card war inflation, overheating, difficult recruitment and high prices of housing is much more violent in this year. So it is time that are more concerned about cost of led bulbs and the trend of the global LED industry.

Looking though the global LED industry, the United States and Europe entrenched high-end market, the market share of about 20%. In 2010, Japan, Korea, Taiwan and the Chinese mainland and the overall market share has reached 81.3%. Asia has become the main production base of LED street light. Clearly, Asia in the future of the global LED status and market competition will become the main battle field.

 

In the future, the LED industry development in Japan, Korea, Taiwan and the mainland China will be crucial, and plays a decisive role in the global LED chess game.

At first, taking a looking at Japan, which is the first global LED lights industry leader and a strong technology development capabilities. From the period of 2000 to 2005, the cost of led bulbs of market share reached 50%, mainly represented by Nichia, Sharp, Toshiba, Panasonic and other companies, while between 2006 and 2010 by the economies of scale and low-cost strategy of Taiwan, and Korea, the impact of mainland government, the market share has dropped to 41.5%. But Japan ranked first in the output value of LED packaging enterprises, in 2009 accounted for 33% of the output of the global LED package. However due to the Japanese products locate the high-end market, high product price, and overall output, so it remained the worldwide leader. And because of the impact of earthquakes in Japan, Japanese consumers have high acceptance of LED lighting, which is the reason why the current Japanese market penetration of LED lighting is far higher than other parts of the reasons. According to Japanese research firm Fuji has aggregated survey results show that it is expected that LED lighting in 2012 will reach 373.8 billion yen, an increase of 69 percent over the previous year. And in 2020, it is expected to increase to 469 billion yen or so. The potential of cost of led bulbs market in Japan is enormous, which makes a lot of LED companies competing to enter.

tunnel lighting led in car application

LED lights now has seen the new vehicles lights applications.The LED lamp is different from incandescent tungsten filament light,  while the use of electric light, the luminous efficiency of up to 80% -90%. The LED has a long life, high luminous efficiency, energy saving, less environmental pollution, etc., so the tunnel lighting led  is not only used in the lighting field, and caused a high degree of attention of the automobile manufacturers, have invested the funds to carry out scientific and technological research, a breakthrough in LED applications in the automotive sector the technical difficulties, the application rate of the LED in the car are increasing year by year.

tunnel lighting led in car application
1, the application of LED car light
In fact, the world’s auto giants has introduced tunnel lighting led  light source for new cars. Like the Japanese Toyota, Mitsubishi, Honda, Nissan and other manufacturers introduced Teana, Crown, Reiz, Cadillac Series; the United States Department of the General Motors Corporation Buick series; Ashkenazi S-Class Benz series has been so using the LED tail lights.  In LED products market, the higher the cost is,  the better in bightness of  LED, however, some manufacturers have also introduced the middle and low-car models of the application of LED light source, such as the Mitsubishi Lancer models launched in the China mainland market.

2, the scope of application of the LED light source in the car
In automotive lighting, it is expected that in 2010, the LED will become a mainstream light source of the majority of car tail light. For example,  TOYOTA the LS600hL, Japan became the first car with LED headlamps. This shows that the exterior light source of future growth potential, the headlights for the next development focus.

The front lights (headlights and turn signals, etc.) The application of LED light source can save valuable space for engines and other related equipment space. Blue, red and green light, LED products mature, widely used, although the white LED used in automotive lighting systems, there are many technical problems. However, with advances in science and technology, brightness, improve the speed up, high brightness LED production capacity increase, as long as the good performance of LED lighting products, prices continued to decline, I believe the tunnel lighting led light source in the application prospects of the automotive lighting systems, good performance, energy-saving the advantages of environmentally friendly, stable and long-life will make the LED to become mainstream products in the automotive lighting.
