Intelligent Lighting Drives LED Drive Transformation

With the huge investment from international lighting manufacturers, the smart lighting market is rapidly heating up and set off a new wave of LED driver and packaging technology changes. In order to be compatible with conventional lamps, the design space for intelligent lighting system circuit boards is extremely limited. Therefore, LED driver and packaging industry have accelerated the development of integrated optoelectronic integration schemes for driving circuits and LED light sources, as well as new types of DOB (DriveronBoard) and COB (ChiponBoard). Packaging technology.

NDP DisplaySearch analyst Qingqing Wei believes that the demand for intelligent lighting systems in Japan and the United States is continuing to rise, and will become the main target market for lighting companies in the future.

NPDDisplaySearch analyst Qingqing Wei said that North America, Japan and China are fully promoting energy-saving policies, and to encourage people and companies to replace the LED lamps and lanterns in subsidy mode, to give LED lighting a new momentum, accelerate the pace of development of the entire industry. As the price of LED products gradually approaches the traditional lighting solutions, the penetration rate increases day by day. The more forward-looking concept of intelligent lighting has also emerged. It has attracted Philips, OSRAM, Toshiba and Rambus lighting solutions suppliers to compete Launch new product offensives.

However, in addition to the need to increase communication, sensing and intelligent automatic control functions, LED smart lighting is more important to be compatible with traditional lighting fixtures to avoid significant changes in the lighting system and affect consumer willingness, while reducing overall installation costs. . Zhao Qingwei emphasized that under the limitation of lighting system's volume, LED driver chips and packaging companies have considered the integration of the driver circuit and light source's opto-electronic integration LED design as the focus of the layout, intensifying the development of new LED driver ICs, and DOB (DriveronBoard) and COB (ChiponBoard) and other packaging solutions.

Zhao Qingwei analysis, taking Philips's latest smart lighting solution -hue as an example, that is equipped with optoelectronic integrated design, combined with ZigBee, LED lights and mobile device applications to provide dimming and wireless network control functions. Spreading the bill of materials (BOM) cost list, the LED light source and heat dissipation mechanism of the non-driver circuit accounted for only about 15%, while the drive circuit for the integrated communication and control scheme was as high as 75%, which indicates that the drive circuit design will promote the development of intelligent lighting. The center of gravity.

It is reported that at present, including Texas Instruments (TI), Fairchild and Dialog Semiconductor and other wafer vendors are committed to the development of low power consumption, small size and higher degree of integration of the LED driver IC, and will be with ZigBee, Low-power Bluetooth (BLE) or digital addressable interface (DALI) and related control technologies. As for LED packaging plants, they are investing in DOB and COB production lines of medium and high-power LEDs to directly combine LED driver ICs, printed circuit boards, and luminaires to assist system operators in achieving an optoelectronic integrated architecture that meets the requirements of intelligent lighting systems.

In addition to communication and control, another important element of smart lighting is the sensing scheme. Zhao Qingwei revealed that many lighting companies have incorporated MEMS, CMOS image sensor (CIS), and even gesture recognition mechanisms into the design of intelligent lighting systems. Panasonic also proposed LED lighting. The concept of communication can be combined with the global positioning system (GPS) of the mobile phone to provide innovative applications for indoor navigation, which is expected to tilt another huge wave of smart lighting market opportunities.

Overall, smart lighting output value will reach US$91 million in 2013 and will double in 2014 to 250 million to 300 million U.S. dollars, and it will look to 1.4 billion in 2019. The scale of $71 million will undoubtedly create a new blue ocean market for the LED lighting supply chain.
