Device for simulating brightness distribution of sky

Abstract

The invention discloses a device for simulating brightness distribution of the sky. The device comprises a semispherical rack and multiple groups of light modulation lamps distributed on the semispherical rack; the brightness and color light of the light modulation lamps can be controlled independently by a controller; a lower circular track is mounted along the bottom circumference of the semispherical rack, an upper semicircular track is mounted on the lower circular track, and a cambered surface of the upper semicircular track is vertical to that of the lower circular track; the upper semicircular track can move along the circumferential path of the lower circular track; and the upper semicircular track is provided with an illuminating light source which can move along the path of the upper semicircular track. The device can simulate any brightness distribution and color temperature of the sky as well as sunlight.

Description

technical field [0001] The invention relates to a building lighting simulation device, in particular to a device for simulating sky brightness distribution. Background technique [0002] Architectural design puts forward requirements for laboratory simulation of building lighting, and the simulation under the condition of reflecting the average value of sky brightness distribution in a certain area can better reflect the actual lighting effect of the building, which requires an artificial device that can simulate any sky brightness The traditional artificial sky and other simulation devices have the following deficiencies: [0003] (1) Unable to simulate arbitrary sky brightness distribution [0004] Traditional artificial sky can usually only simulate full cloudy sky or uniform sky. Since the brightness distribution of this kind of simulation device can not be controlled and adjusted, it does not have the performance of simulating any sky brightness distribution. [0005]...

Problems solved by technology

[0003] (1) Unable to simulate arbitrary sky brightness distribution

[0004] Traditional artificial sky can usually only simulate full cloudy sky or uniform sky. Since the brightness distribution of this kind of simulation device can not be controlled and adjusted, it does not have the performance of simulating any sky brightness distribution.

[0005] (2) Cannot simulate dynamic sky brightness distribution

[0007] (3) Cannot simulate the change of color temperature of sky light

[0008] The traditional artificial sky does not have the performance of simulating dynamic sky color temperature changes due to design and structure reasons
