LED architectural lighting has been diversified with the use of various public buildings and commercial spaces, and the proportion of installation using LED light sources has gradually increased. LEDinside recently interviewed Mr. Yang Lichang, Chairman of Macroblock, Inc., and asked him to talk about the driver and controller development needed for LED architectural lighting, the latest market application trends of LED display, and the development of LED backlight driver products.
Introduction to the relationship between LED drivers and the market
Chairman Yang Lichang said that the Shanghai World Expo in China, the 2010 World Cup in South Africa and a variety of large-scale events have led to significant growth in LED display screens and LED architectural lighting. The company's current product shipments reached 30 million units per month. In terms of shipments, LED display IC shipments accounted for 85% of the total, but its unit price decline was relatively high, which was a mature product, and its revenue accounted for Only 80% of non-display IC revenues have come to 20%. In the non-display IC, half is the driver of architectural lighting, and the other half is the driver for general indoor lighting and LED backlighting.
The chairman of the board believes that LED architectural lighting is mainly a project order for various architectural lighting. Currently, it is stable at the stage of continued growth. The driver for lighting is in the trend of more and more orders, especially LED bulbs. aspect. Overall, several important requirements for LEDs have grown significantly, and the company is providing the weapons needed by various LED application lighting manufacturers, namely LED drivers, through which it can control the driving of currents and change the brightness of LEDs. The degree, the color of the RGB LED, and the time of lighting and igniting are among the important components in architectural lighting, LED display, LED backlight application, and LED lighting.
LED architectural lighting is increasingly hot
The chairman of the board takes the popular LED architectural lighting as an example to illustrate the key points of the development and needs of LED drivers in this field. He said that the LED driver products that have been assembled are used in LED architectural lighting. They also need to be equipped with driver boards, controllers, signal conversion cards, and data receiving cards to control the color of LED point sources on architectural lighting. Bright performance, to make a variety of customer needs for lighting decoration or lighting practical effects.
In the collocation solution, the accumulation is in cooperation with ARC Solid-State Lighting, which allows the customer to get the product, and the system can be used immediately, which is very helpful for expanding business opportunities. of. For example, in the case of the famous Mediatek, the company launched a consumer IC, which is also used to make the matching design circuit board available to customers, thereby expanding more markets and satisfying customers. The degree will also increase. In this way, accumulation can raise the threshold of competition.
Jinxin plus accumulation, and the matching automation equipment manufacturers, through this team combat way, let the system manufacturers to pick up the building project or the standard case, and then provide LED controllers, cooperative LED lamps to the manufacturers to carry out construction.
At present, the LED architectural lighting market is almost always a standard case. It is not easy to standardize and the system architecture is different. Therefore, manufacturers need to spend more effort to deal with it. In particular, LED architectural lighting is presented outdoors, and it is necessary to overcome the problems of waterproofing, hot plugging, and EMI electromagnetic interference. For example, he uses LED architectural lighting on the exterior wall of a building, and cannot interfere with other people's communications. Processing, can not let other things interfere with the performance of LED architectural lighting source, IC. The stability of the product is very important, because once the construction is completed, there is a problem, it needs to be repaired. Just calling a crane to deal with it will cost a lot of money and time, which is not enough for small manufacturers.
In terms of the global LED construction market, the market in China and the Middle East will be relatively large, and there will be some big cases in Europe and the United States. These markets have high quality requirements for LED architectural lighting. Lighting design and environmental considerations are important.
The company has received a case from the 2010 Guangzhou Asian Games in mainland China, using accumulating drives in the white LED control drive.
LED indoor and outdoor lighting and LED street lights
As for general LED lighting products, it is divided into two parts, one is white LED and the other is RGB LED. White LEDs are almost all standard products, so most of them are AC to DC ICs. To give them a power solution, safety regulations should also be noted. While RGB LEDs are used in commercial spaces, buildings, and signage, replacing traditional neon lights is a trend in this market.
He also pointed out that the pressure on the price reduction of E27-specified LED bulbs is increasing. In the future, like the MR16 with hundreds of millions of products in the world, the price will become more and more cheaper. At that time, the market acceptance and shipment volume will be enlarged.
In addition, the LED street light technology used outdoors is relatively difficult, and the problem of heat dissipation and optics is solved in this respect, and the accumulation provides a solution for the power IC.
LED backlight IC for LCD TVs is actively developed in cooperation with international companies
Accumulation is now also cooperating with international manufacturers. At present, LED backlight ICs are already in the design in stage. It is also necessary to make control boards to assist manufacturers, and design many different versions to different customers. At present, Taiwanese factories, as well as overseas Korean and Japanese manufacturers, as well as manufacturers in mainland China, are cooperating.
He used the Japanese factory Sharp as an example. The company has a liquid crystal TV with a direct-lit LED backlight. It is in the form of RGB LED. This aspect is a part of accumulating good, and regional dimming is the future trend. Estimated 2011 At the time, the turnover of LED backlight drivers will grow significantly.
The new trend of LED display is to match with buildings and commercial space.
Finally, he mentioned a new trend in the LED display that accumulates the largest revenue source, namely the LED curtain screen. This is a semi-transparent LED display that can be used in commercial spaces with both lighting and display effects.
The driver required for the LED display screen will go toward the trend of color correction, high refresh rate, and brightness correction.
The frequency of picture update of LED display will increase upwards, especially for concerts and sports events, and more such high refresh rate products are needed. In addition, low power consumption, energy-saving design, cost performance, appearance flexibility, enhance architectural aesthetics and penetrating design
It will be the focus of future development, and it is expected that there will be a wave of replacements for LED displays.
