Abstract

This invention relates to the field of illuminance detection technology and discloses an illuminance meter capable of continuous horizontal and vertical illuminance detection. The meter includes a tripod mechanism with a height adjustment mechanism at its top. This height adjustment mechanism comprises a quick-adjustment rod, a fine-tuning screw, and a height adjustment ring. The quick-adjustment rod can slide at the end of the tripod mechanism. The height adjustment ring and the fine-tuning screw are both located at the top of the quick-adjustment rod. When the height adjustment ring rotates, it drives the fine-tuning screw to move axially.

This ensures the illuminance meter probe remains horizontal, improving detection accuracy. Furthermore, the tilt adjustment mechanisms operate via a worm gear mechanism with a self-locking effect, ensuring stability after adjustment.

Description

Technical Field

[0001] The invention relates to the technical field of illumination detection, in particular to an illumination meter capable of realizing continuous detection of horizontal and vertical illumination. Background Art

[0002] People have higher and higher requirements for the quality of lighting environment. To ensure the quality of lighting visual environment, the lighting environment must be tested. The two most important test indicators are horizontal illuminance and vertical illuminance. The existing horizontal illuminance and vertical illuminance are tested separately. The horizontal illuminance is mostly tested by the inspectors using illuminometers with support platforms at different heights, and the vertical illuminance is mostly tested by the inspectors holding the illuminometers vertically fixed on support platforms at different heights. Although it can realize the detection of illumination, there are still some problems: inaccurate detection, the height and inclination of the illuminance meter have a great influence on the detection result, because most illuminance meters are of different thicknesses and sizes, and the supporting platform lacks height fine-tuning function and inclination adjustment function, resulting in inaccurate detection result of horizontal illumination, and the vertical illumination is fixed by hand, so the error of the detection result is even greater; detection is inconvenient, because the inspectors often need to detect the horizontal illumination and vertical illumination of different heights at the same time when they arrive at a place, the adjustment of different heights and the conversion between horizontal illumination and vertical illumination bring great trouble to the inspectors; the detection efficiency is low, the existing technology requires the horizontal illumination and vertical illumination of each height to be continuously adjusted each time with a length measuring device, and the conversion between horizontal illumination and vertical illumination requires re-measuring the height, which will be very time-consuming, and the large number of test points each time will greatly extend the overall test time.
