With the development of the LED lighting market, the requirements for cost reduction and efficiency improvement are increasing. It has been in the “buddy†medium-light engine has begun to develop rapidly, and many development companies have begun to accelerate the product layout in the field of light engines such as AC-COB.
Recently, the domestic white light packaging giant Hongli Optoelectronics released the second generation AC COB new AC LE series, with higher withstand voltage value and stability; compatible with some two-way thyristor dimmer, to achieve intelligent two-way dimming function.
The relevant person in charge of Hongli Optoelectronic Engineering Technology Center said that the AC LE series products have applied for invention patent protection, and the future development of the products will be dimmable, high power and high integration; more attention will be paid to the improvement of thyristor dimmer compatibility. The color temperature is adjustable, the product power is increased, the size is reduced, and the die package is realized.
At the beginning of 2015, the High-tech Research Institute LED Research Institute (GGII) once said that more companies will participate in the LED light engine market in the next two or three years, when the product performance is expected to accelerate, and the LED lighting market will continue to benefit. Development, LED light engine market has a good imagination.
The development of the market also confirmed the original judgment of GGII.
In addition to Hongli Optoelectronics, packaging companies including Jingke Electronics, Xinli Light Source, Meiya Optoelectronics, Zhonghao Optoelectronics, Xinyue Optoelectronics and Tongfang Optoelectronics have recently accelerated their product layout in the AC-COB market.
Xiao Guowei, chairman of Jingke Electronics, said: "The LED lighting industry has developed to the present, the two driving forces of cost reduction and efficiency improvement will make the value chain of the whole industry more reflected. The LED industry should form integrated epitaxial chips and package integration models. Group or light engine supplier."
In general, in order to assemble products, traditional LED downstream lamp manufacturers often purchase components such as lamp beads, driving power supplies, and aluminum substrates, which are not only expensive to manufacture, but also have more or less compatibility stability between devices of various manufacturers. problem.
The light engine integrates the lamp bead, aluminum substrate and drive power into a module, which can effectively solve these problems once it is delivered in volume.
Xiao Guowei believes that the light engine promotes the assembly of LED light sources and lamps at the low end of the value chain, reducing costs and saving design space. More importantly, this technology can truly highlight the intelligent design of LED lamps and the value of lighting brands. â€
In the 2015 Golden Globe Awards, Xinyue Optoelectronics Co., Ltd. and Zhonghao Optoelectronics participated in the awards with COB light engine products.
“The COB light engine is easier to install in the finished product, reducing labor costs and improving efficiency,†said Zou Yiming, general manager of Xinyue Optoelectronics.
"We provide our customers with high-quality light engines, equipped with light, lenses, reflectors, and radiators. Customers only need to consider their lighting design and application, instead of worrying about others." Zou Yiming said.
Yang Fan, general manager of the same party's optoelectronics, also said that in 2016, the other side of the same side of the COB is the focus of the AC-COB, which is suitable for the customer's needs, that is, the photoelectric engine, which can be directly connected to the AC110/220V power supply. It not only further reduces the processing cost and labor cost of the lamp factory, but also greatly shortens the product production cycle.
According to Yang Fan, AC-COB of the same side is mainly used in LED wall lamps, and has successfully entered the supply chain of world-class manufacturers.
"The LED industry chain is moving towards integration. In the future, if we can integrate the light engine into more systematic information, including intelligence, sensing, dimming and other functions, it will be integrated into the carrier of the light engine. At that time, a new leap in technology will be realized, and this is also the development direction of the light engine," said Zhang Qiang, executive director of Xinli Light Source.
