Description

Technical Field

[0001] This utility model relates to the field of illuminance meter calibration technology, and specifically to an easy-to-operate illuminance meter calibration device. Background Technology

[0002] An illuminance meter is an instrument specifically designed to measure illuminance. It measures the degree to which an object is illuminated, that is, the ratio of the luminous flux received by the object's surface to the illuminated area. To ensure the accuracy of the illuminance meter during use, it needs to be calibrated frequently.

[0003] A search revealed a patent document with publication number CN207991689U that discloses a lux meter testing and calibration device. This calibration device can be adjusted to the required distance by sliding on a smooth rod. With the help of the scale on the side, the adjustment is convenient. In addition, the height of the support frame is adjustable, making positioning convenient. The positions of the lux meter and the light source can be made consistent by adjusting in the same way. The whole device greatly improves the convenience of testing.

[0004] However, in practical applications, lux meters may receive light from various angles. For example, in lighting design evaluation, it is necessary to measure the illuminance of the lighting area by the lamps at different angles. By setting different angles of the light source, these actual scenarios can be simulated, and the measurement accuracy of the lux meter under different lighting angles can be more comprehensively tested. However, the above-mentioned device can only adjust the detection distance of the lux meter laterally and cannot adjust the setting angle of the light source, which reduces the calibration effect.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model discloses an easy-to-operate illuminance meter calibration device.

[0031] Example 1

[0032] This utility model provides, for example Figure 1-5 The illuminance meter calibration device shown includes a base frame 1 and an adjusting screw 2 rotatably disposed inside the base frame 1. A slider 3 is threadedly sleeved on the wall of the adjusting screw 2. The slider 3 is slidably disposed inside the base frame 1 and a support column 4 is fixedly disposed on its top. A support frame 5 is rotatably sleeved on the top of the support column 4. A rotating rod 6 is rotatably inserted through the upper end of the support frame 5. A swing plate 7 is fixedly sleeved on the wall of the rotating rod 6. A mounting plate 8 is contacted at the upper end of the swing plate 7. A binding assembly is disposed on the top of the mounting plate 8.

[0033] The end of the adjusting screw 2 extends out of the base frame 1 and is fixedly equipped with a crank handle 9. The upper end of the inner wall of the base frame 1 is fixedly equipped with a base plate 10, and the top of the base plate 10 is equipped with an illuminance meter clamping assembly.

[0034] Before calibration, the illuminance meter and light source are fixed in position using the illuminance meter clamping and binding components. Then, according to the calibration requirements, the crank handle 9 is turned, which drives the adjusting screw 2 to rotate. The adjusting screw 2 is threaded into the slider 3, allowing the slider 3 to slide left and right within the base frame 1. The support column 4, support frame 5, and light source on the mounting plate 8 at the top of the slider 3 also move accordingly, thereby changing the lateral distance between the light source and the illuminance meter. After adjusting to the appropriate position, the crank handle 9 is stopped. Then, by the relative rotation of the support column 4 and support frame 5, and the longitudinal rotation of the rotating rod 6 and swing plate 7, the plane angle and pitch angle of the illuminance meter can be adjusted, facilitating illumination calibration of the illuminance meter at different angles and improving the calibration effect.

[0035] Example 2

[0036] Example 2, based on Example 1, aims to enable the light source to be positioned at different angles and heights, such as... Figure 1 and Figure 3-5 As shown, a collar 11 is fixedly provided at the bottom of the support frame 5. The collar 11 is sleeved on the outside of the support column 4, and springs 12 are fixed at both ends of the bottom. An outer toothed ring 13 is fixedly provided through the springs 12. An inner toothed ring 14 is fixedly provided at the top of the slider 3. The inner toothed ring 14 is sleeved on the outside of the support column 4 and is engaged with the outer toothed ring 13. Two symmetrically arranged push plates 15 are fixedly provided at the top of the outer toothed ring 13.

[0037] A horizontal plate 16 is fixedly installed at the lower end of the outer wall of the support frame 5. A sleeve plate 17 is slidably fitted on the outside of the horizontal plate 16. A guide hole 20 is opened at the top of the sleeve plate 17. A T-shaped block 21 is slidably inserted in the guide hole 20. The bottom of the T-shaped block 21 is fixedly connected to the horizontal plate 16. An elastic telescopic rod 18 is fixedly installed at the top of the sleeve plate 17. A strip hole 19 is opened inside the swing plate 7. The upper end of the elastic telescopic rod 18 passes through the strip hole 19 and is fixedly connected to the mounting plate 8.

[0038] A support plate 22 is fixedly installed on the back side of the support frame 5. A worm gear 23 is rotatably installed inside the support plate 22. A worm wheel 24 is fitted on the worm gear 23. The worm wheel 24 is fixedly sleeved on the outside of the rotating rod 6.

[0039] To change the illumination angle of the light source in the plane, push the push plate 15 at the top of the outer gear ring 13 upward. The outer gear ring 13 moves upward against the elastic force of the spring 12 and disengages from the inner gear ring 14. At this time, the support frame 5 can be rotated to adjust to the required plane angle. Then, release the push plate 15. The spring 12 pushes the outer gear ring 13 downward so that it re-engages with the inner gear ring 14, fixing the plane angle of the support frame 5 and completing the adjustment of the plane angle of the light source.

[0040] When adjusting the pitch angle, the worm gear 23 inside the support plate 22 on the back of the support frame 5 is rotated. The worm gear 23 drives the worm wheel 24 that it cooperates with to rotate. The worm wheel 24 is fixedly sleeved on the outside of the rotating rod 6. The rotating rod 6 rotates accordingly, which in turn drives the swing plate 7 to swing. When the swing plate 7 swings, the mounting plate 8 is pushed by the elastic telescopic rod 18 to change the angle, thereby adjusting the pitch angle of the light source. After observing that the angle of the light source has reached the required calibration angle, the rotation of the worm gear 23 is stopped. During this process, the sliding cooperation between the horizontal plate 16 and the sleeve plate 17 enables the mounting plate 8 to provide continuous and stable horizontal support for the light source.

[0041] Example 3

[0042] Example 3, based on Example 1, aims to ensure stable positioning of the lux meter and light source, thereby guaranteeing stable calibration. Figure 1-2 As shown, the illuminance meter clamping assembly includes a U-shaped plate 25, which is fixedly mounted on the top of the base plate 10, and a locking screw 26 is threaded through its side. One end of the locking screw 26 is rotatably fitted with a clamping plate 27, which is located inside the U-shaped plate 25 and its bottom contacts and engages with the bottom of the inner wall of the U-shaped plate 25. The other end of the locking screw 26 is fixedly fitted with a knob 28.

[0043] The binding assembly includes a strap 29, which is fixedly mounted on the top of the mounting plate 8, and both ends of the inner wall are fixedly provided with Velcro tape 30.

[0044] Before calibration, place the illuminance meter to be calibrated inside the U-shaped plate 25 on the top of the base plate 10, turn the knob 28 so that the locking screw 26 pushes the clamping plate 27 to clamp and fix the illuminance meter, place the light source to be calibrated on the mounting plate 8, tie the light source with the strap 29, and stick it firmly with the Velcro tape 30. This completes the determination of the position of the illuminance meter and the light source, ensuring stable calibration.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
