Building sunshine simulation device

Abstract

The invention discloses a building sunshine simulation device, comprising a pair of circular guide rails, a light-emitting device, an intermediate support used for bearing the circular guide rails, and a base. The circular guide rails comprise outer circular guide rails and inner circular guide rails; the outer circular guide rails are arranged outside the inner circular guide rails, and rotate relative to the inner circular guide rails; the inner circular guide rails are in fixed connection with the intermediate support; the light-emitting device is in fixed connection with the outer circular guide rails; the intermediate support and the base are in movable connection through a linkage mechanism; the linkage mechanism is used for adjusting the inclination angle of the intermediate support relative to the base. According to the invention, the light-emitting device simulates sunshine, and shortens the distance between a light source and a model to be measured; the circular guide rails rotate to simulate the azimuth of the sun; the intermediate support and the base form the inclination angle on the plane vertical to the ground to stimulate the elevation angle of the sun. The building sunshine simulation device can accurately stimulate the locus of the sun, and perform building sunshine simulation, and possesses the advantages of small size, compact structure, accurate simulation, etc.

Description

technical field [0001] The invention relates to a sunshine simulation device, in particular to a building sunshine simulation device. Background technique [0002] Building sunlight is an important factor to be considered in architectural design and planning design. Building sunshade and shadow analysis in planning projects all put forward requirements for laboratory simulation measurement of building sunshine. Therefore, it is necessary to develop a building sunshine simulation device. Traditional sunshine simulators usually have two defects: [0003] (1) Use spotlights to simulate sunlight, which takes up a lot of space [0004] Traditional sunshine simulation devices directly use spotlights as lamps for simulating sunlight. Due to the simple optical path and in order to ensure that the light illuminates the model to be tested in parallel, a long distance is usually required between the light source and the model to be tested in this type of device, resulting in This typ...

[0004] Traditional sunshine simulation devices directly use spotlights as lamps for simulating sunlight. Due to the simple optical path and in order to ensure that the light illuminates the model to be tested in parallel, a long distance is usually required between the light source and the model to be tested in this type of device, resulting in This type of device is not compact in structure and takes up a lot of space;

[0005] (2) Sun trajectory simulation is not intuitive

The fixed position of the lamps in this type of simulation device cannot intuitively simulate the sun's trajectory
