Even in a dark office, you can enjoy the bright sunshine outdoors. It turned out that the sun was "stolen" through special channels.
The Suzhou Institute of Architectural Design and Research was transformed from an old factory building. A total of 96 solar lighting systems were installed in the entire office building. This system can direct natural light directly into the room. In this office building with an area of ​​more than 12,000 square meters, ample daylight lighting can be obtained without a single day of electricity.
How to collect sunlight?
Using the lens technology to import natural light from the outside, the reporter saw that the daylighting system indoor port is similar to the common ceiling lamp. Through the disk-shaped lampshade, one can see a spherical "bulb". Unlike ordinary ceiling lamps, the “bulbs†here are all kinds of spherical lenses.
Shu Jinrong, head of the Suzhou Institute of Architectural Design and Design, told reporters that the daylighting system uses lens technology to introduce the natural light of the office building roof into the office building through a special pipe, and then through the ports set in different areas of the office building, Office provides natural light. The entire daylighting system does not need any Other energy source, and has the function of transmitting light, not transferring heat, and filtering ultraviolet rays, and the utilization of natural light introduced from the outdoors can reach 97%.
According to reports, the illumination intensity of each indoor port of daylighting system is equivalent to 200-300 watts of electric light. Suzhou Office of Architectural Design and Research, an office with an area of ​​more than 1,000 square meters, can meet the office lighting needs of over a hundred designers as long as 16 daylight lighting system ports.
“The lighting mask is a very bright eye. It can find out the sun no matter it is cloudy or rainy. It's like collecting rainwater. The lighting mask collects sunlight, but in cloudy and rainy days, the light will be darker,†said Cha Jinrong.
What does it feel like indoors?
The light was comfortable and the supermarket sales increased. Later, the reporter went to a company in Suzhou Industrial Park and visited the installed pipe-type daylighting device. Company employees told reporters that since this special device was installed, each company's workplace was sunny.
Zhu Hong, the company's marketing director, said that the pipe-type daylighting device can filter out infrared rays that are harmful to the human body in sunlight, and the heat insulation effect is also very good. It can also adjust the light brightness through switches.
“A lot of foreign supermarkets have adopted tube-type daylighting lighting devices. With this device, supermarket sales can be increased by up to 40%.†Zhu Hong told reporters that since natural light is more realistic than light, under the influence of natural light, supermarket goods look It will feel better and it will also increase the customer's desire to buy.
The reporter learned that the price of a pipe-type daylight lighting system installed in office buildings is approximately 50 to 200 yuan per square meter. According to estimates, a lighting device with a pipe diameter of 550 mm uses a year (8 hours a day) of electricity saving, which is equivalent to reducing the use of a 1096-watt lamp.
At present, this lighting technology has been used in the Beijing Olympics Judo, Taekwondo Hall and the National Grid Pavilion of the Shanghai World Expo. Suzhou City Architectural Design Research Institute, Industrial Park Logistics Center and other units have also adopted this type of pipe-type daylighting lighting device.
