The specific performance of the light characteristics of the membrane structure carport is explained from three aspects:
1. High daylighting coefficient
The sunlight shining on the roof is transmitted into the room in the form of diffused light. From the inside, the roof becomes a continuous bright side whose intensity changes due to the relative position of the roof and the sun. The daylighting coefficient (that is, the ratio of the natural light intensity of the indoor and outdoor surfaces) of the tension film structure can generally be as high as 10%; in traditional construction, the light can only enter the room through limited daylighting windows, and the daylighting coefficient is less than 3 %. Even in a cloudy day, the light level in the membrane structure room can meet the basic requirements of most activities.
2. No glare
Because the transmitted light and reflected light entering the membrane structure room are diffuse light, glare is unlikely to appear. However, it is necessary to consider the arrangement of the glass lighting area and shading to avoid the glare caused by direct light.
3. Good color
In the interior of the membrane structure carport, people will have a good color perception of white or off-white membrane materials, because these two colors show the characteristics of linear spectrum transmission of visible light. The degree of transmission increases with the wavelength of the transmitted light, which makes the transmitted light slightly warmer than the incident light. The transmission spectrum is different from the fiber and its characteristics, the thickness of the coating and the additional surface layer. The manufacturer should give more specific information. The transmission spectrum of PTFE-coated glass fiber membranes compared to PVC-coated polyester fiber membranes.
