Mini LED market is hot

Since the Micro LED has not been used by Apple on the new generation of iWatch, all aspects of its technology and applications have become more rational, and related manufacturers are also actively cooperating with the application.

Mini LED market is hot

At the same time, the Mini LED has gradually entered the reality. From top to bottom, manufacturers have followed suit. After last year’s trial, the major terminal application plants have basically completed the prototype design. From the exhibitions in recent years: Samsung, Lumens and other manufacturers have introduced Mini LED applications.

The market expects 18 years to be the beginning of the large-scale application of Mini LED.

Compared to current conventional applications, Mini LED does have its unique advantages:

For backlight applications, the Mini LED is generally a direct-down design that uses a large number of dense patches to achieve a smaller area of ??dimming. Compared to a traditional backlight design, the Mini LED can be implemented in a smaller light mixing distance. Good brightness uniformity, higher color contrast, and thus achieve ultra-thin, high color rendering, power saving of the end product.

At the same time, because of its design can be used with flexible substrates, with the curved surface of the LCD can also achieve a similar OLED surface display under the condition of ensuring quality, on the other hand, because the current OLED is self-luminous organic materials, in terms of reliability Mini LED It is also very advantageous; based on the mature LED industry chain, the cost of using Mini LED backlight is only about 60% of the same size OLED, which is very competitive in all aspects.

For display applications, the RGB Mini LED overcomes the defect of wire bonding and reliability of the positive-fit chip, and at the same time, it combines the advantages of the COB package to make it possible to further reduce the dot pitch of the display screen. The visual effect of the corresponding terminal product is greatly enhanced, and the viewing distance is also improved. Can be greatly reduced, so that indoor display can further replace the existing LCD market.

On the other hand, the use of RGB Mini LED with a flexible substrate can also achieve a high-quality display of the curved surface. With its self-luminous characteristics, it has a very broad market for some special modeling needs (such as automotive display).

As can be seen from the above, the Mini LED has a great advantage over other competitors in the current situation faced by the LED. Based on this, the various manufacturers are also researching, from the current situation, although the size of the chip and the chip is installed. The small pitch chips are similar but there are many differences.

Its technology has the following characteristics and difficulties:

Judging from the process route, the current Mini LED adopts the flip chip structure, mainly because the flip chip does not need to be wired, which is suitable for the needs of the ultra-small space, and it is also suitable for a variety of materials of the package substrate, and it is precisely because of this, The reliability is also obviously improved, and the maintenance cost of the use of the terminal products is reduced. Therefore, during the actual production process, the control of the flip-chip process is extremely important. At the same time, in the case of a small size, the flatness of the welding surface, the design of the electrode structure, and the ease of welding. The adaptability of the welding parameters and the latitude of the package are the difficulties and focuses of its design.

For the backlight application of Mini LED, due to the ultra-thin terminal requirements, combined with the cost and control difficulties, the chip can be achieved in a wider range of LED chip spacing to achieve a smaller light mixing distance, and then reduce the thickness of the whole machine, so how Implementing the light emission control of the chip and the consistency in the later use process are the key points.

For display applications using RGB Mini LEDs, the brightness concentration required for conventional small-pitch chips, the brightness consistency at low currents, and the low and consistent capacitance characteristics are eliminated. The use environment and post-maintenance require higher requirements for reliability. It is the red light chip that needs to carry out the substrate transfer during the process of manufacturing flip-chips. The overall process is more complicated, and the transfer technology, production yield control, and reliability during use are the key considerations.

Due to the small size of the Mini LED chip and the requirement for consistency of light color, the Mini LED is currently used in an all-in-ones mode. The operating efficiency is low. If the number of products is expected to increase with the market, the application needs to be in a single product. When working on a chip with more than one hundred kilowatts, the efficiency limit is more obvious. Therefore, how to cooperate with the application side and effectively improve the operating efficiency is also the current focus.

Tottenham Stadium will use LED lighting

A few days ago, Tottenham Hotspur of the English Premier League club decided to use LED lighting in its competition venues and venues. It is reported that the venue can accommodate 61,559 seats.

Tottenham Stadium will use LED lighting

LED goes into the Premier League: Tottenham Stadium will use LED lighting

The Spurs updated their latest information on the stadium’s roof structure on its official website.

“The roof was installed with 324 LED sports lights that provide flood lighting for the venue.”

However, the Spurs declined to disclose their LED lighting suppliers.

“Once all matters have been finalized, we will announce the lighting supplier in due course.” “Before this, we cannot disclose which one is.”

Last summer, the Spurs announced that Austrian LED lighting manufacturer Zumtobel is their lighting partner. The project is worth 850 million pounds (about 7.423 billion RMB). It focuses on the “fan experience” of digital lighting. . However, the project does not include site lighting.

At that time, the team did not even promise to use LED lighting. Although LED stadium lighting is emerging in many professional sports venues (such as Major League Baseball and NFL stadiums), stadium operators are sometimes opting to upgrade non-LED lighting systems. It is unclear whether Zumtobel won the bid for venue lighting.

The 324-inch LED luminaires will be mounted on 54 roof pillars, each with 6 inches. The roof is made up of glass panels that can be angled on the stands, but keep the playing field open.

The Spurs hope to open the stadium before the start of the 2018 season in August. A National Football League match between the Auckland Commando and the Seattle Seahawks will be held on October 14.

China’s low-cost LED products swept the Korean lighting market

According to a report from Korean media MoneyToday, recently the LED lighting industry and the Korean Photonics Industry Promotion Association (KAPID) reported that the Korean LED lighting market certified in 2015 was about 1 trillion won (approximately US$850 million). Over the years, the LED lighting market has maintained a growth rate of 10-15%, but now it is due to oversupply, and it has hit a low-price bloody battle.

China's low-cost LED products swept the Korean lighting market

At the beginning of 2015, the Korean Commission for Corporate Partnership excluded the LED lighting industry, which is suitable for small and medium-sized enterprises, in order to encourage large companies to invest in non-governmental LED lighting markets other than government procurement projects. Joint competition to stimulate the growth of the LED market.

However, the situation was unexpected. What emerged in the market was not the competition between South Korean SMEs but the low-priced products in China that gradually swept the market.

According to data from the Korea Optical Industry Promotion Association, LED lighting was still suitable for SMEs in 2013. The private market is about 500 billion won, of which 99% is estimated to be produced in China.

According to industry figures, in the government procurement market of 300 billion won, LED was still limited to the competitive area of ??small and medium-sized enterprises, and it can maintain 100% production in South Korea. However, in the private market, whether it is B2B or B2C, almost all of China’s LED products are in the world.

Recently, a report published by the Korea Consumer Protection Institute (KCA) also pointed out that according to sales volume and visibility, 17 out of the 19 LED lighting products in Korea are produced in China by OEM and ODM.

According to the analysis, although LED has been lifted from the suitable industry, South Korean companies are still eager to import low-priced land-based products, mainly because there is no confidence in the LED market. LED lighting industry sources said that large companies are competing to import low-priced Chinese products, mainly to make up for the loss of the LED lighting business unit before, to increase profitability.

However, with the growing threat of low prices in China, the phenomenon at this time is that more and more SMEs have abandoned self-development of LED modules. People in the industry believe that South Korean SMEs have not yet reached the mass production stage after self-developed model organizations. The decree specifying suitable industry species was lifted, leaving SMEs facing the need to compete with large companies for the low price of Chinese products imported, leading to SMEs’ ??competition. The industry has given up on the development of original technologies. It is unclear whether the Korean government’s LED lighting policy will change in the future.

India LED lighting market promising

The United States Super Bowl stadium for the first time enabled LED floodlights

Miami, United States local time on January 29, the well-known sports lighting manufacturer Qualite announced the completion of the University of Phoenix, Arizona Stadium lighting renovation project, the entire system used a total of 312 sets of Q-LED floodlights to achieve the overall energy-saving 75% illumination. The remodeled stadium will serve as a dedicated stadium for the 2015 American Football Super Bowl.

The United States Super Bowl stadium for the first time enabled LED floodlights

Features 1: Single lamp maximum 1000 watts, 115,000 lumens luminous flux

Feature 2: Achieve 4000K-6500K range of color temperature adjustment

Feature 3: to achieve remote monitoring and dimming, color and other functions

As a luminaire that can be broadcast with top-rated events, the Q-LED floodlight set must deliver the stability, accuracy and stroboscopic performance required for international HD video broadcasts with a single lamp of up to 1000 watts and a luminous flux of 115,000 lumens the powerful features ensure digital and slow motion capture the same lighting effects as natural daylight.

At the same time, through the use of wired and wireless digital control system, you can achieve 4000K-6500K range of color temperature adjustment, and create a comfortable and unique stadium atmosphere.

Structurally, the circular light emitting surface of the Q-LED floodlight is concentrically formed by four LED light emitting modules. Each LED light emitting module integrates a component that specifically suppresses the strobe, and is also integrated with the NEMA protection standard alone The lens module and the lens module are integrated with a cooling fan, so that the heat generated during the operation of the LED chip can be transmitted to the radiator at the back of the lamp by an active convection method through an aluminum die casting process, so as to effectively dissipate heat.

Q-LED floodlight lamps in the central also set to monitor the working conditions of lamps and wireless management capabilities to support the controller for remote monitoring and dimming, color and other functions. The entire lamp with IP66 protection.

The power supply, Q-LED projector supports 208VAC, 240VAC, 277VAC, 347VAC, 480VAC and other voltage specifications, the power efficiency is greater than 94%, power factor greater than 0.95, THD

“It’s fantastic,” said Peter Sullivan of the University of Phoenix, Arizona. “The new fixtures are excellent in many ways and are super slow motion capture enough to provide unbelievable clarity.”

According to foreign media reports, the current Super Bowl venue will enable LED lighting for the first time, rather than the traditional metal halide lamp. The University of Phoenix Stadium – Home of the Arizona Cardinals and the Super Bowl – was equipped with LED lighting last year. Because LEDs are more luminous than older fixtures, the stadium only needs 312 LED lights and replaces 780 old-fashioned metal halide lamps originally installed at the venue.

It should be noted that the University of Phoenix Stadium is not the first stadium to deploy LED lighting, because NRG Stadium is. As home to the Houston Texans, it also has new lights installed this season.

Finally, one of the biggest advantages of LED lighting is the ability to light instantly, rather than requiring half an hour of “warm up” time (for optimum brightness) as traditional fixtures do.

Low-carbon industry in 2020 will exceed 10 trillion

January 5, the State Council released the “13th Five-Year Plan” energy-saving emission reduction work, “clear” 13th “energy-saving emission reduction work of the main objectives and priorities of the national energy-saving emission reduction work carried out a comprehensive deployment. The Plan clearly states that by 2020, the total output value of green and low-carbon industries such as energy-saving and environmental protection, new energy equipment and new energy vehicles will exceed 10 trillion yuan and become a pillar industry.

Low-carbon industry in 2020 will exceed 10 trillion

According to incomplete estimates, more than 660 cities in the whole country consume more than 700 million kilowatt-hours of electricity during the year due to the over-pavement. They need to spend 350 million yuan. Since more than 700 million kilowatt-hours of electricity are emitted, a corresponding increase in emissions of carbon dioxide and sulfur dioxide Harmful gases, damage the air quality is not conducive to environmental protection, but also increase light pollution and light interference, hindering people’s normal work and rest and physical and mental health. Therefore, starting from the street lights, promote green lighting, environmental protection, energy conservation has an important significance.

The city’s energy-saving emission reduction is inseparable from traffic green lighting. Street lights are essential municipal infrastructure. Lighting of urban road lighting as a large consumer of energy, the energy-saving effect of a direct impact on energy-saving emission reduction results. Relevant data show that 66% of the cities in the United States have devoted themselves to the development of smart cities and that there are nearly 600 cities in China carrying on the construction of intelligence.

Baidu energy-saving street lights readily available, we can see the nationwide transformation of street lights.

After the energy-saving retrofit of the street lamp, not only can it exert a far-reaching impact on society, but also directly generate considerable economic benefits. It will help to save the energy consumption of urban public lighting, create a low-carbon environment-friendly city and build a livable area.

In addition, in addition to the energy-saving benefits of retrofitting LEDs from traditional light sources, secondary energy savings are achieved through intelligent control and avoidance of waste.

Shenzhen dark energy LED lights wireless dimming wisdom drive power as an example. Compared with the traditional “one-size-fits-all” street light, LED street light wireless dimming intelligent driver power supply can optimize the lighting settings, reduce switching time reasonably, which not only reduces operating costs, but also extend the lamp life.

The accelerated development of urban construction, urban lighting construction more and more focus on the city’s image building, road lighting and landscape lighting requirements continue to escalate, you need to support high-tech means with remote control, automated management, simple design, easy installation, Use of safe, stable operation, strong anti-interference, energy saving, cost-effective smart street lighting system. Shenzhen dark energy station at the forefront of LED drive technology in the world, world-class engineers integrate electrical, magnetic, thermal, design high reliability LED intelligent drive power solutions, will continue to respond to the voice of energy-saving emission reduction and create a green economy.
