Description

Technical Field

[0001] This utility model relates to the field of lighting performance testing technology, specifically to a device for adjusting the lighting intensity of building exterior windows. Background Technology

[0002] There are tens of thousands of testing devices related to the daylighting performance of building exterior windows nationwide. Each device needs to be calibrated after installation, replacement of light sources or lamps, or spraying. The number of calibrators is very large, which makes the convenience and practicality of the calibration method an urgent requirement.

[0003] The existing verification method follows the requirements of section 5.2.2.2 and Appendix D of GB / T11976-2015. The average illuminance on the plane of the specimen opening should not be less than 1000 lx, and the illuminance difference should not be greater than 1%. It is necessary to adjust the positions of multiple metal halide lamps on-site to regulate the light uniformity, and then measure the illuminance at multiple points according to the requirements of Figure D.1 in Appendix D, and finally calculate the average illuminance according to the formula in D.1.

[0004] In conclusion, adjusting so many locations would require numerous adjustments to meet the standard requirements for average illuminance, making the operation impractical and necessitating many repetitions to achieve normal operation. This would indirectly increase the time and cost. Utility Model Content
