With the fierce investment from international lighting manufacturers, the smart lighting market is rapidly heating up, and a new wave of LED driver and packaging technology changes is taking place. In order to be compatible with traditional lamps and lanterns, the design space of the circuit board of the intelligent lighting system is extremely limited. Therefore, LED driver and packaging manufacturers have accelerated the development of optoelectronic integration solutions that integrate drive circuits and LED light sources, as well as DOB (Driver on Board) and COB (Chip on Board) and other new packaging technologies.
NPD DisplaySearch analyst She Qingwei believes that the demand for smart lighting systems in Japan and the US market is continuing to rise, and will become the main target market for lighting industry in the future.
NPD DisplaySearch analyst She Qingwei said that North America, Japan, and mainland China are promoting energy-saving policies and encouraging people and companies to replace LED lamps with subsidies, so as to give LED lighting a new momentum and accelerate the development of the entire industry. As the price of LED products is gradually approaching traditional lighting solutions, penetration is increasing day by day, and more forward-looking smart lighting concepts have also emerged, which has attracted lighting solutions providers such as Philips, OSRAM, Toshiba and Rambus. Launch a new product offensive.
However, in addition to the addition of communication, sensing and intelligent automatic control functions, LED smart lighting is more important to be compatible with traditional lamps to avoid large-scale lighting system changes that affect consumers' willingness to adopt and reduce overall installation costs. . She Qingwei emphasized that under the limitation of the volume of the lighting system, LED driver chips and packaging manufacturers have regarded the integrated optoelectronic LED design with integrated drive circuits and light sources as the layout focus, and are intensively developing new LED driver ICs and DOB (Driver on Board ) And COB (Chip on Board) and other packaging solutions.
According to She Qingwei's analysis, taking Philips' latest intelligent lighting solution-hue as an example, it is equipped with a photoelectric integrated design, combined with ZigBee, LED lights and mobile device applications to provide dimming and wireless network control functions. Spread out the Hue Bill of Materials (BOM) cost list, the LED light source and heat dissipation mechanism of the non-driving circuit only account for about 15%, and the driving circuit integrating communication and control schemes is as high as 75%. Center of gravity.
It is reported that chip manufacturers including Texas Instruments, Fairchild and Dialog Semiconductor are committed to developing LED driver ICs with low power consumption, small size and higher functional integration, which will be paired with ZigBee , Bluetooth Low Energy (BLE) or Digital Addressable Interface (DALI) and other related control technologies. As for the LED packaging factory, they invest more in the DOB and COB production lines of medium and high-power LEDs to directly integrate LED driver ICs, printed circuit boards and lamps to help system manufacturers realize the photoelectric integrated architecture to meet the requirements of intelligent lighting systems.
In addition to communication and control, another important element of intelligent lighting is the sensing scheme. She Qingwei revealed that many major lighting companies have incorporated sensing mechanisms such as micro-electromechanical systems (MEMS), CMOS image sensors (CIS), and even gesture recognition into the design of intelligent lighting systems; Panasonic has also proposed LED light The concept of communication can be combined with the global satellite positioning system (GPS) of mobile phones to provide innovative applications of indoor navigation, which is expected to stir another wave of huge opportunities in the smart lighting market.
Overall, the output value of smart lighting will reach US $ 91 million in 2013, and will double to US $ 250 million to US $ 300 million in 2014, and will reach 1.4 billion in 2019. The scale of US $ 71 million will undoubtedly create a new blue ocean market for the LED lighting supply chain.
