[0002] An integrating sphere system is used to test some important parameters of lamps, such as color temperature, luminous flux, luminous efficacy, color rendering index, etc., and to measure whether the lamps are qualified through the tested parameters. The integrating sphere system mainly consists of a spectral test host, an integrating sphere and a base. During the test, the lamp is placed inside the integrating sphere, and the integrating sphere senses the color temperature, luminous flux, luminous efficacy, color rendering index, etc. of the lamp, and the spectral test host calculates and displays the parameters.

[0003] Currently, when testing lamps, the position of the lamp inside the integrating sphere is fixed. The light intensity received at different positions inside the integrating sphere is different, and the distribution of the light intensity inside the integrating sphere is uneven, which will cause certain errors in the parameter test of the lamp. Therefore, a novel integrating sphere system with high uniformity is needed. Content of the Utility Model

It is characterized in that: a placement plate 5 is fixedly installed inside the integrating sphere 1. A position adjustment plate 6 is slidably arranged on the placement plate 5. A placement pad 7 is fixedly installed inside the position adjustment plate 6. A clamping plate 8 is arranged on the inner surface of the bottom of the position adjustment plate 6. A soft pad 9 is fixedly installed on one side surface of the clamping plate 8. A guide rail 11 is fixedly installed on the inner surface of the bottom of the position adjustment plate 6. A card slot 10 is opened at the bottom of the clamping plate 8, and the card slot 10 is clamped on the guide rail 11. A clamping plate position adjustment mechanism 12 is jointly arranged on the clamping plate 8 and the position adjustment plate 6. A position adjustment plate driving mechanism 13 is jointly arranged on the placement plate 5 and the position adjustment plate 6;

[0023] Open the integrating sphere 1, place the lamp to be tested on the placement pad 7, connect the lamp to the power supply inside the integrating sphere 1, then adjust the position of the clamping plate 8 through the clamping plate position adjusting mechanism 12, and clamp and fix the lamp with a set of clamping plates 8. The soft pad 9 is in direct contact with the lamp, which can reduce the damage to the lamp caused by clamping. Turn on the lamp and close the integrating sphere 1. Detect parameters such as the color temperature, luminous flux, luminous efficacy, and color rendering index of the lamp when it emits light through the integrating sphere 1, and process and display them through the spectral test host 4. During the test, adjust the position of the position adjusting plate 6 through the position adjusting plate driving mechanism 13, so as to adjust the light emitting position of the lamp, so that the light intensity received at different positions inside the integrating sphere 1 has high and low changes, and uniform light intensity can be received at different positions. Then take the average value of the test data to improve the accuracy of the test data.

[0024] In one embodiment, specifically, the clamping plate position adjusting mechanism 12 includes a threaded hole 121 opened on the position adjusting plate 6, an adjusting screw 122 is threadedly installed in the threaded hole 121, and the bottom end of the adjusting screw 122 is rotatably installed in the clamping plate 8;

[0025] In order to clamp and fix the lamp with the clamping plate 8, rotate the adjusting screw 122 into the position adjusting plate 6. Under the action of the threaded hole 121, the adjusting screw 122 moves into the position adjusting plate 6, thereby pushing the clamping plate 8 to move towards the lamp on the position adjusting plate 6. The card slot 10 is engaged with the guide rail 11, which can guide the movement of the clamping plate 8. A set of clamping plates 8 approach each other to clamp and fix the lamp.

[0026] In one embodiment, further, a retaining ring 124 is fixedly installed on the outer surface of the adjusting screw 122, and a retaining groove 123 is opened in the clamping plate 8. The retaining ring 124 is rotatably installed in the retaining groove 123;

[0027] In order to make the clamping plate 8 move with the movement of the adjusting screw 122, the retaining ring 124 rotates in the retaining groove 123, which can prevent the adjusting screw 122 from falling out of the retaining groove 123, and can make the clamping plate 8 move with the movement of the adjusting screw 122.

[0028] In one embodiment, further, the other end of the adjusting screw 122 is fixedly installed with a knob 125, and a plurality of friction strips 126 arranged in a circumferential array are fixedly installed on the outer circumference of the knob 125;

[0029] In order to facilitate driving the rotation of the adjusting screw 122, rotating the knob 125 can drive the rotation of the adjusting screw 122. The friction strips 126 can increase the frictional resistance during contact and prevent slipping during rotation.

[0030] In one embodiment, specifically, the position adjustment plate driving mechanism 13 includes a support plate 131 fixedly installed at the bottom of the placement plate 5. A driving motor 132 is fixedly installed on the support plate 131. The output end of the driving motor 132 is fixedly installed with a rotating rod 133.

The bottom of the position adjustment plate 6 is fixedly installed on the connecting block 136;

[0031] To change the light-emitting position of the lamp, start the driving motor 132 on the support plate 131. The rotation of the driving motor 132 can drive the rotation of the rotating rod 133. The rotation of the rotating rod 133 can drive the rotation of the driving groove 134. The rotation of the driving groove 134 will drive the slider 135 to slide. The sliding of the slider 135 will drive the connecting block 136 to move. The movement of the connecting block 136 will drive the position adjustment plate 6 to move, so as to adjust the light-emitting position of the lamp and ensure the uniformity of the illumination at different positions inside the integrating sphere 1.

[0032] In one embodiment, further, a guiding block 137 is formed on the surface of the placement plate 5. The connecting block 136 is slidably installed in the guiding block 137;

[0033] Through the setting of the guiding block 137, the sliding of the connecting block 136 in the guiding block 137 can guide the movement of the slider 135. When the rotating rod 133 rotates, the slider 135 can be driven to move through the driving groove 134.

[0034] Working principle: When in use, open the integrating sphere 1, place the lamp to be tested on the placement pad 7, and connect the lamp to the power supply inside the integrating sphere 1. Rotating the knob 125 towards the position adjusting plate 6 can drive the adjusting screw 122 to rotate. Under the action of the threaded hole 121, the adjusting screw 122 moves into the position adjusting plate 6, thereby pushing the clamping plate 8 to move towards the lamp in the position adjusting plate 6. The clamping groove 10 is engaged with the guide rail 11, which can guide the movement of the clamping plate 8. A group of clamping plates 8 approaching each other can clamp and fix the lamp. The soft pad 9 is in direct contact with the lamp, which can reduce the damage caused by clamping to the lamp. Turn on the lamp and close the integrating sphere 1. The integrating sphere 1 is used to detect parameters such as the color temperature, luminous flux, luminous efficacy, and color rendering index of the lamp when it emits light, and the spectral test host 4 is used for processing and displaying. When testing, start the driving motor 132 on the support plate 131. The rotation of the driving motor 132 can drive the rotating rod 133 to rotate. The rotation of the rotating rod 133 can drive the driving groove 134 to rotate. The rotation of the driving groove 134 will drive the slider 135 to slide. The sliding of the slider 135 will drive the connecting block 136 to move. The movement of the connecting block 136 will drive the position adjusting plate 6 to move, thereby adjusting the light emitting position of the lamp, so that the light intensity received at different positions inside the integrating sphere 1 has high and low changes, ensuring the uniformity of the light received at different positions inside the integrating sphere 1. Then, take the average value of the test data to improve the accuracy of the test data.
