The package innovation seminar hosted by Gaogong LED was successfully held in Shenzhen Qingqing World this afternoon. Wang Mengyuan, general manager of Zhonghao Optoelectronics, shared the scene with "The Future of Light Engine".
For the light engine (LED Light Engine), the industry is no stranger. As early as four or five years ago, many companies have begun to intervene in the development of light engines.
Wang Mengyuan believes that the market size of the light engine is still very small, about 7-8 billion this year, and it is expected to reach 2.5 billion next year.

The LED light engine is a device module that is interposed between an LED luminaire and an LED illuminator.
The LED COB light engine adds the electric drive module to the advantages of the COB light source application and optimizes the interface with the lamp housing, making it easier to assemble into LED lamps.
Wang Mengyuan believes that the current trend of miniaturization of LED lamps is obvious:
1. The structure space is limited (the power supply is large and needs to occupy a large space and cannot be installed in a compact luminaire);
2, spotlights, decorative lights and multi-headlights (such indoor lamps are more exquisite and beautiful, small in size, no more space to install the power supply, but also have cost requirements);
3, outdoor floodlights (small size, portability trend).
The COB light engine has unique advantages and value, which can reduce the production threshold and research and development costs of LED lighting manufacturers and improve production efficiency. In addition, the size, modularity and intelligence of the light engine can enhance the overall design space of LED lamps.
Wang Mengyuan mentioned that all the light engine products of Zhonghao Optoelectronics can be used with the upper insulation ring (bracket) to effectively protect the surface of the light source and achieve the effect of insulation safety.
At present, Zhonghao Optoelectronics' "Chenguang" ceramic series light engine has passed the 9000-hour reliability test of the Energy Star LM-80.
In terms of the dimming function of the light engine, Wang Mengyuan said that the current general-purpose single-stage dimmer mainly has two problems: first, the power is reduced by more than 20%; second, the brightness is adjusted to the critical point of closure, and the LED will Blinking appears.
Wang Mengyuan was on the spot to find a partner at the high-tech LED packaging innovation forum. At present, the market in North America has strong demand for 5W/7W COB dimmable light engine, and new 12W/18W/30W high power COB dimming requirements are added. Zhonghao Optoelectronics hopes to find a matching IC solution that adapts to dimming.
