LED lamp china will become mainstream demand in the next two years

After many years development of China’s LED industry, although it already is LED production big country and the application of a large country, yet due to lack of industry-proven national standards in the LED industry, the detection system is yet to establish, which not only cause the LED industry enterprises of cohabitation, also led to the quality of LED products.

LED lamp china will become mainstream demand in the next two years

2012 LED Lighting price cuts very fast, which makes LED lighting is rapidly into various application areas. NXP Semiconductors (NXP), director of marketing of lighting products in Greater China Wang Yongbin told reporters, “we found a new trend, that is, non-dimmable LED lighting products are very popular with Asians’ like, including Japan and South Korea and other developed countries also favor non-dimmable products, which may be related to the habits. Europeans and Americans prefer dimmer lighting. “this is a good news for LED industry, because at present, the price of non-dimmable IC are cheaper than adjustable optical IC prices by about half, while the IC is still the most important  part of the entire LED fixtures. Wang Yongbin then added: “We found another trend that continued LED bulb and lamp series. In the next two years, led lamp china will start to become mainstream demand.” So, the next two years, NXP LED Flood Light semiconductor programs providers will focus on non-dimming and high-power lamps on the market, because of the huge growth potential of the Asian region.

Apart from the above trend, Wang Yongbin particular to disclose the current lighting manufacturers for demanding power factor, because many countries, including China, specifically requested certain lighting the PF is greater than 0.9, and there will be a subsidies for standard product. “For example, in China’s energy-saving projects in the bidding for the FP to plus two points, which PF are greater than 0.9, and the Chinese government will give up posts. And in the European Energy Star requirements, when a power is greater than 25W, the lighting of PF must be greater than 0.9. “he pointed out that the program of some IC manufacturers want to achieve high power factor, which need from the outside to control implementation, and that will increase the cost, while NXP can  achieve from the chip, which not only to facilitate the design, and also reduced costs. “Like SSL2109A controller, due to a dedicated circuit, so it can achieve that PF is greater than 0.9 and less peripheral, simple design and convenient.” For example, he said.

Ruthless anatomy Philips Hue LED electronics

We can see that it relates to the smart mobile phone hardware products, due to the presence, the future cannot be DIY and using the software community capacity of manufacturers, will face more and more development bottleneck.
Now some manufacturers like own R & D and the use of an internal closure standard, but its development capacity can not meet the future demand, also cannot produce the hardware.Therefore do not open interface standard, practice, perhaps more in line with the trend of the times.

Ruthless anatomy Philips Hue LED electronics

To summarize the Hue to bring about some changes, the traditional home appliances and electronic products, is not only around the appearance and design competition, a large number of products can quickly become Connected networking equipment. A networking device, not only means that you will be able to complete a simple remote control in the led electronics, they will know the time and weather, know your social account and schedule, know your preferences, they can also help with your other networked devices ( such as Hue and infrared sensor cooperation serves as a warning device ).

Sensor and communication, the cloud background for further development, will greatly reduce the device manufacturing and communication cost, so that only need to spend the extra few dollars or even more than ten dollars, you can change all appliances.

Starting from Hue, I think, the most important should be Control4, this traditional meaning of ” intelligent home furnishing manufacturer “.
Why? Because we may enter the ordinary family intelligent control products, price cut directly on the back of one or two zero, so that ordinary consumers from the original dare to buy, which is intelligent mobile phone popularity to the traditional home appliances industry.

In fact, through similar LED Panel Light control system in led electronics, Nest, Wemo socket system, sound system SONOS and so on, everyone can use the smart mobile phone DIY 90% traditional intelligent home furnishing function, not only can be removed from the new decoration suffering (all wireless system ), but the money spent on just the traditional meaning of intelligent home furnishing .Then, the future smart home furnishing where to go? Venture to do forecast:

1, plug-and-play: no configuration, can be used directly to plug in the power;

2, a comprehensive mobile phone manipulation: do not use this friendly platform for interaction, too wasteful;

3, gateway lightweight: because the mobile phone computing power, gateway is not essential, if there must be, it must be very lightweight bargain;

4, expanding and upgrading ability: sales is only functional platform delivery, function but also with the use of the product upgrade;

5, open and fun: maybe next time you open App, found that the contribution of new function, put your dream of things to achieve;

6, Kickstarter models: leading personalized hardware product ideas, to giant products integrated scheme constitute the supplementary and challenge;
7, low-cost market strategy: rapid price and market offensive strategy, resulting in a large number of star products.

LED lighting replaced era: Yuan Fang, how do you think of this?

farewell to incandescent lights, support green light” theme of the campaign in the Chinese Academy of engineering, this month, China will carry out formally phasing out the incandescent lamp road map. Industrial and commercial departments will be investigating the illegal sale of incandescent behavior.

According to the new century LED network reporter,the EPA is developed to enhance the added mercury products and related industry of mercury pollution control policy, intends to prohibit the use of liquid mercury and reply manual pouring mercury fluorescent lamp production, alteration, expansion project. Obviously, this is to LED industry,which is a major good news. At the same time, the ancient town of lights Fair in October 18th officially kicked off.

LED lighting

Ai Disen said enterprise development of lighting industry holds a conservative attitude. The industry generally believe that, LED lighting market development is not expected coupled with the lighting of terminal market which is not mature, the majority of consumers enjoys good price, the LED lighting market development is developing more and more slow. Look, despite policy and environmental protection and energy saving factors such as power, but the LED lamp has more than 130 years in the use of inertial and obvious price advantage of the incandescent lamps compared with energy-saving, the intermediate force balance to win the game,there is a long way to go. In this way, how to encounter obstacles for LED Street Light industry and how to break? LED lighting replaced era: Yuan Fang, how do you think of this?

I can say when the whole cast a brick: 1, indoor lighting EMC mode does not form; 2, bulb 3W is a standard product, mainstream ex-factory price to be 8 -10rmb, 3, the price with the dive off enterprises will become extremely tragic; 4, there will be next year to the industry chain of vertically integrated competition Na involved; 5, large traditional lighting enterprises encounter patent litigation, patent war shifting people’s nerve; 6, the traditional strong brand distributor shielding new LED competitor, blocked channel resources; 7, the lack of capital supporting enterprises difficult to carry out the production; 8, have a professional operation team and financing channel, the quality of the brand for the resources; 9, who first education channel is the first to occupy the initiative; 10, energy-saving lamp countdown has begun; 11, light efficiency increased by 30%, prices fall 30%, every year will go down a stage; 12, emerging generation of dealers by LED machine rise, around the channel pattern rewriting; 13, new industry managers with new knowledge structure, ability structure rise; 14, some new brand was born, a number of traditional brand will be down; 15, each category appear representative brand.

LED lighting will completely solve the problem in price

LED lighting has been used in medical and hotel which need 24 hours of lighting in place and street lighting for long time lighting areas, other areas because of price, it has not been able to scale into the lights However, today bright two years may be a turning point.

LED lighting will completely solve the problem in price

In the autumn of 2012 Hongkong Street Light Fair, director Wang Yongbin on this print analysis, ” LED lighting price grows very fast in 2012, which makes the LED lighting is quickly into the various fields of application. ” ” And, we found a new trend, namely a dimming LED lighting products are very popular amongst Asians like, including developed countries such as Japan and South Korea also favored non-dimming products, which may be associated with the use of habits. Europe and the United States people like dimming lighting. ” The LED industry is a good news, because at present, non-dimming IC price ratio is much cheaper, while IC is the LED lighting in the share of the cost and its the most important part of it. Wang Yongbin said : ” we found another trend , the year after next LED lamps will begin to become the mainstream of demand. ” So, the next two years, NXP LED semiconductor solution provider will focus on non dimming and high power lighting market, because of the huge potential for growth in Asia.

Currently on the market for single stage and two stage LED driving structure of confrontation, Wang Yongbin said, NXP is a single stage architecture defenders. Main reason has the following: one is NXP in a single stage with long time accumulation and advantage; two I, a single level controller can be integrated high voltage MOSFET tube; three ,a single stage and easy to use, easy to design, customers need only two weeks can be successfully; four ,currently the single stage has a cost advantage, double BOM single stage BOM expensive than about 10-15%.

Finally talks about some LED lighting manufacturers to do their own research and development to drive the IC/ components of vertical integration trend, Wang Yongbin think this is just a temporary phenomenon, which will not become mainstream. ” It’s difficult to do lighting company while to do electronic part, the future will be the professional division of labor, the driving part of independence. ” He thought.

To build the LED industry base in Jiangxi province

Riding the Nanchang development of LED industry, Ji’an city will speed up the pace for the development of LED industry steps.

Ji’an proposed around the construction of semiconductor lighting industry that gathering area Jinggang shan Economic and Technological Development Zone, Hedong Economic Development Zone,  Suichuan Country, Jiangangshan City Industrial Park, vigorously develop all kinds of LED lighting and LED video products to create “LED industry base in Jiangxi province.

To build the LED industry base in Jiangxi province

Gutai corridor is the only provincial electronic information industry base in Jiangxi Province. Ji’an adhere to the semiconductor lighting industry, including electronic information industry as a pillar industry to focus on fostering Jiangxi Province, the largest electronic information industry base. Ji’an industry express, until the end of last year, Ji’an electronic information enterprises amounted to 345, which specializes in semiconductor lighting products production enterprises up to 15 LED device packaging capacity ranks first.

It is understood that the one Linsen that rooted in Jinggan shan can produce more than 100 pieces, with an annual output of 50 million device package capability, in the low-end LED Flood Lights (semiconductor lighting) devices in the field of packaging capacity ranks first in the country; settled in Jishui County industrial Park Jiatai Electronics that specializes in the research and development, production, and sales of all kinds of LED side backlight, color night view display modules and other products. The entire project estimated to gain 600 million yuan annual year, which will bethe Jiangxi production back light largest enterprises.

Marketing developing

The industrial development is the market. If there is no market, and no order, the industrial development can not contribute too much.

It is understood that, previously, marketing of LED products in Jiangxi Province is mainly relying on their own, the main players is in the market of Jiangsu and Zhejiang and other places. However, with the expansion of the product yield, and increassed varieties, how to further expand the market willl be the decisive factor in  Jiangxi LED industry.

We believe that through the joint efforts of all parties, Jiangxi LED industry will be able to rose to the challenge in the fierce competition in the market, and embrace a better future for the sound and rapid development!

2012 Jiangxi LED industry development situation analysis

Jiangxi LED industry in recent years has achieved rapid development. And Fujian industrial has become the four largest clusters. Nanchang, Ji’an, Shangrao and other places in the LED industry, which is ushered in a period of rapid development. It is understood, Nanchang as China semiconductor lighting industrial bases. In the semiconductor lighting industry occupies an important position. The existing semiconductor lighting has 20. And in 2011, the main business income is 3.13 billion yuan. The initial formation of the High-tech Zone, as the two companies to Lattice Power Union Optical lead to the proliferation of the Jinxian countries and industrial parks, industrial structure, industrial development beginning to take shape.

2012 Jiangxi LED industry development situation analysis

Expected to 2015, Nanchang will nurture and develop more than two output value, which will exceed 30 billion yuan, with strong technical innovation ability, and leading enterprise in the country, formed a number of unique advantages, brand internationally competitive products, strive to achieve the output value of 300 billion yuan of the city’s LED and related industries. Until 2020, we will cultivate and develop a number of master core technologies, leading enterprises with international competitiveness, radiation and leading the LED industry of the province.

While the LED industry in Jian and Gaoan develop very fast. The following will be a comprehensive review. Jiangxi LED industry development.

Nanchang LED industry development takes shape

According to understanding, development of LED industry is the core of the important initiatives to create a Nanchang drives progress of Jiangxi province economy growth. After development, Nanchang as China’s semiconductor lighting industrial bases, semiconductor lighting emitting materials and devices in the country which already has apparent comparison advantages. The LED industry has become one of the industries of Nanchang city.

In the first half of 2012, Nanchang, more than 20 LED Panel enterprises realized main business income of 2.12 billion yuan. The initial formation of the High-tech Zone, as the two companies to Lattice Power Union Optical leads to the proliferation of the Jinxian counties and industrial parks, industrial structure, industrial development beginning to take shape.

To create the domestic first-class LED industry technology innovation and production base

The aim of Nanchang aspects, relying on the silicon substrate technology, advantage with completely independent intellectual property rights, vigorously build LED products export base, and will eventually be based on domestic, global and domestic first-class LED industry, technological innovation and production base in Nanchang playing.

Shenzhen big world debt of nearly 7 million, LED lighting suppliers petition to the government(1)

November 29, the weather is rain, Shenzhen gathered more than 100 suppliers in front of the Civil Center, holding “security – big horizons return my hard-earned money” banner, it is particularly striking. The presence of a packaged device suppliers said that they hope the city government come forward and give the supplier a word.

This reporter has learned that, Shenzhen vision Photoelectric Co., Ltd. (hereinafter referred to as the “horizons”) is a typical representative in one of the South China LED display industry. Industry sources said that, the 2011 horizons sales reached 3 billion, which belong to the LED lighting display industry. That is, in January 2011, the one who has always been good, and mergers and acquisitions of Security Technology (China) Co., Ltd. (hereinafter referred to as “CSST”) to acquire a 70% stake in the big vision.

Shenzhen big world debt of nearly 7 million, LED lighting suppliers petition to the government(1)

“At that time, when CSST shares directed to the LED concept heat. They hope to be able to put the big vision into the company’s overall package listing plan” One person said, before the CSST shares, big vision actually already stuck in the fund predicament.” And at that time, the company and CSST is signed agreement on gambling, but for the company, after all, it is a life-saving straw.

However, in recent years, the domestic  LED lighting display industry competition is intense with each passing day.

In 2012, the LED Tube display industry makes price war greatly. With a strength of the manufacturers hope to through the price war to eliminate a part of small scale manufacturer. The LED display screen which has entered the period of integration presents the situation of contention of a hundred schools of thought. But by the factor of slowdown, hair falling interest rates, LED display screen are difficult to have investment opportunities.

The High technology LED Industrial Research Institute (GLIT) released the latest display industry report, 2012 domestic LED display prices continue to fall, year-on-year decline in 15%-20%. At present, the main channel of the LED display manufacturer’s product gross margin level has been reduced to 10%-15%. Engineering channel product gross margin is still more than 20%.

At this time, big vision of “great leap forward” sales strategy, not only cannot play “self-help” effect, but let the company bogged down in the more serious capital predicament.

LED future enter into the civil area, electricity supplier platform as a springboard

Despite the global economic down turn in 2012, the mainland LED lighting and civilian market unpaired scale, but the LED industry remains growth of over 20%, mainly derived from intensive policy of the mainland government.

Mainland’s central government in 2011 had announced LED Development goals in the 12th Five-Year Plan. The LED lighting clearly point out: until 2015, LED Grow Lights enter into people’s lives. The Ming market penetration rate is 30%, incandescent will eliminated completely in 2015; followed in 2012, the mainland ministries has introduced different emphases LED future lighting development plan.

LED future enter into the civil area, electricity supplier platform as a springboard

Looking ahead to 2013, the policy continued, municipal project released a single, as well as subsidies terminal, it will help continue to drive the mainland of LED domestic demand market, escort the mainland for LED industry. And the duration implementation incandescent road map start on October 1, 2012, despite the current two, third-tier cities still have individual malls selling banned incandescent, but most businesses and incandescent lamp manufacturers have begun to transition into the sales and production of CCFL and LED lights. With the time over passed, the firm implementation of the continent out incandescent road map, the LED market space will increasingly broad.

Although civilian LED market has not yet demonstrated the huge demand, yet the continent’s huge population base, and improve the standard of living, increase awareness of energy conservation and recognition of high-tech products respected. So it indicates the enormous potential of the civilian market. In order to win the market, and the mainland many led future lighting manufacturers have also layout path. Most traditional lighting manufacturers choose to cut from the original traditional path the LED pathway, and the emerging LED manufacturers tend to be faster, more efficient, low-cost e-commerce platform. Topology believe that, with the perfection of the mainland e-commerce platform, the rapid increase of the number of users, the 2013 “electricity + LED” LED better way to enter the civilian market. Whether it is the emerging LED manufacturers or traditional lighting, manufacturers will do the electronic business in the platform.

Continental panel industry giant BOE recently said that with the commencement of the Beijing BOE 8.5 generation production line and the Hefei 8.5-generation line, the future of LED back light module demand with panel production carve out and supporting growth BOE hope through shares before there is co-operation between the East Bay, Formosa on quality LED manufacturers to enter the field of LED back light. However, for central enterprises to stake in Taiwan enterprises is difficult.

Analysis of LED fluorescent tubes

LED connection mode (series/parallel) and wide voltage range: in order to enable LED fluorescent tubes work under wide voltage range: 85VAC-265VAC, the connection mode (series/parallel) of LED tubes is fairly important. Current power supplies generally use non-isolated step-down power supply. In wide voltage requirements, the maximum output voltage should be no more than 72VAC, the input voltage range is 85VAC-265VAC. In other words, the series string number should be less than 23. Also need to limit the number of parallel strings. Too much current will generate more heat. Normally, 6/8/12 branches with the total current less than 240mA.

 

ED connection mode (series/parallel) and wide voltage range: in order to enable LED fluorescent tubes work under wide voltage range:

 

Relations between LED Tunnel Light series-parallel connection and PFC power factor, wide voltage range: there are three major cases of PFC power supplies in the market: a. without PFC special circuit, the PFC is normally about 0.65; b. with passive PFC circuit, the PFC is normally around 0.92; c. with active source 7527/6561 circuit, PFC can reach up to 0.99. But this case is twice as expensive as the second one. Comprehensively, b is the most commonly used mode.

 

Precision of constant current: some constant current sources in the market have a relatively low precision, like the popular PT4107/HV9910/BP2808/SMD802 constant current plans with an error of +/- 8% or +/- 10%. In normal condition, +/- 3% is enough. In this way, 6 branches with error +/- 0.5% for each branch, or 12 branches with error +/- 0.25 for each branch can meet such requirements. High precision will also increase the production cost of LED fluorescent tubes. But for LED lamps, 17mA or 17.5mA does not make too many differences.

 

Isolated/non-isolated: generally, isolated power supplies can make as 15W. LED drivers are too large to be embedded into LED tubes with limited size. Thus isolated power supplies can only be made as 15W tops, hardly find power supplies in the market with output power greater than 15W. In terms of LED tubes, isolated drivers have very low cost-effective. Non-isolated driver is the mainstream.

 

Power efficiency: the ratio of output power to input power. This parameter is very important. Low power efficiency means that most of the input power is converted into thermal energy and wasted. Such drivers will generate a large amount of heat within tubes. LED is a type of component that vulnerable to heat. Thus LED lighting fixtures need high power efficiency, normally no less than 80%.

Five selection points of LED fluorescent lamps

Currently, LED fluorescent lamps market is very active. Manufacturers can be divided into three types: a. original LED chip manufacturers, started to penetrate to downstream packaging and application business, having little knowledge in circuit and power supply; b. ordinal general lighting application manufactures, entering a new field, having little knowledge in circuit; c. new comers, they just started their new venture in the field of LED lighting business, having no knowledge in LED power supply. LED power supply (LED driver) is the most important part of LED fluorescent lamps. Improper selection of LED drivers will reduce the performance of LED tubes or even disable the normal work of them.

 

Currently, LED fluorescent lamps market is very active. Manufacturers can be divided into three types:

Why must be a constant current: characteristics of LED semiconductors seriously influenced by the environment: LED current will increase with the raise of temperature and input voltage. Working under over-rated current for a long time, the service life of LEDs will be declined drastically. Constant current can fix the internal working current in diverse temperatures and voltages.

The match between LED fluorescent lamps and lighting boards: some customers are accustomed to design lighting boards before finding matched power supplies. It is rather difficult: too much current Vs too small voltage (I>350mA, V<40V); otherwise too much voltage Vs too small current (I<40mA, V>180V), leading to a result of over-heated, low efficiency, insufficient input voltage range. The best solution is to choose an optimal connection mode (series/parallel), making current/voltage on each LED chip remain the same. By doing so, LED power supplies can get the best performance.

The operation current: the general LED rated operating current is 20mA. Some makers would set the initial current as 20mA. In fact, working under such current, LED Tunnel Light chips will generate a large amount of heat. After numerous comparison tests, 17mA is an ideal value. The total current of N-way parallel branches is 17*N.

The operation voltage: generally, the suggested operation voltage of LED chips is 3-3.5V. According to measurements, most of LED chips will work under 3.125V voltage, which has been proved a relative ideal value. The total voltage of M-way series branches is 3.125*M.

Dimensions: height is the main restriction factor. LED chips used for LED T6/T8 tubes should have a height no more than 9 mm, and no more than 15 mm for T10 tubes. Long in length can help to conduct heat.
