Fudan's latest LED research results are mixed with natural light to save energy 4

On the morning of the 15th, the Department of Light Source and Lighting Engineering of Fudan University released the latest research results of a number of LEDs. Among them, the team led by Associate Professor Ge Aiming, for the first time, mixes natural light with LED, and the two are integrated into one, which is a new breakthrough in the application of LED lighting system. The team confirmed through simulation experiments that using integrated natural light and LED hybrid lighting system while maintaining the same indoor light level can save 66.28 more energy than traditional fluorescent lighting, and save more than 41.62 than the LED instead of fluorescent lamp. Electrical energy, truly energy efficient. According to reports, the indoor illuminator of this integrated hybrid lighting system is designed as a small lamp composed of natural light and four LEDs. The outdoor natural light is collected by the light-receiving panel, and is transmitted to the natural light illumination lamp in the middle of the small lamp through the light guide tube as the main light source in the daytime; the LED around the natural light illuminator is controlled by the sensor, and is automatically dimmed according to the change of the introduced natural light at any time. Or fill light, the solar energy stored in the daylight panel will provide power to the LED. Whether it's in the early hours of the morning or at dusk, the outdoors is cloudy or sunny, this lighting system provides 24/7 comfort lighting for the interior. Ge Aiming said that the lighting system has broad application prospects in underground shopping malls, parking lots and large conference rooms that need to be illuminated during the day. Fudan's LED results today include: high-power UV LED light curing system, aircraft cabin lighting, LED applications in agriculture and medical applications, tunnel lighting, OLED material basic research, quantum dot LED technology, etc. Technology, or has entered the field of application, has practical significance for real life and production. For example, LED lighting technology can increase the light source for some under-lighted crops to ensure its output; LED ultraviolet light can be used for disinfecting water, and can quickly cure paint and reduce pollution; LED is also used for dental treatment.
