Description

Technical Field

[0001] This invention relates to the field of optical carrier testing equipment technology, and in particular to a full-space light intensity testing device for optical carriers. Background Technology

[0002] The full-space light intensity or spectral distribution of an optical carrier (such as optical modules, light-emitting devices, optical lens groups, etc.) is the core indicator for evaluating its optical performance and directly determines the actual use effect of the optical carrier in scenarios such as lighting, display, and laser applications. Currently, the light intensity testing of light carriers mainly relies on traditional distributed photometers or manual multi-directional sampling and detection. However, these methods have many limitations in practical applications: traditional distributed photometers mostly adopt single-axis or dual-axis rotation structures, which can only collect light intensity on a single horizontal or vertical plane of the light carrier, making it difficult to meet the testing requirements of covering the entire space. The degree of freedom is relatively poor, and for irregular light carriers with strict testing route requirements, blind spots are likely to occur, resulting in incomplete distribution of light intensity test data. Meanwhile, manual multi-directional sampling and testing requires manual adjustment of the placement angle and detection position of the optical carrier, which is not only time-consuming and labor-intensive, but also prone to introducing test deviations due to human operation errors. Therefore, in order to meet the actual needs of full-space light intensity testing of optical carriers and to develop a light intensity testing device that can achieve accurate, efficient and universal three-dimensional angle testing in full space, this application proposes a full-space light intensity testing device for optical carriers. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This optical carrier uses a full-space light intensity testing device, employing a horizontal and vertical circular ring structure as the basic carrier for full-space detection. It is equipped with a holder for an excitation device or a detection device. Through the cooperation of a motor and a gear transmission mechanism, it can move circumferentially along the inner wall of the vertical circular ring structure, thus enabling the excitation device and the detection device to move in the longitudinal direction. Under the drive of the motor, the horizontal circular ring structure can drive the vertical circular ring structure to move synchronously, thereby enabling the excitation device and the detection device to move in the longitudinal direction.

[0014] 2. The light carrier uses a full-space light intensity testing device. A horizontal moving groove is provided at the junction of the horizontal and vertical circular structures. The moving unit is equipped with a telescopic guide rail, which can conveniently adjust the horizontal position of the vertical circular structure and the distance between the excitation device, the detection device and the light-emitting carrier.

[0023] Please see Figure 1-8 The present invention provides a technical solution: a full-space light intensity testing device for a light carrier, comprising a support frame 400, a stage 600, a horizontal ring structure 140, a vertical ring structure 210, a motion drive unit, a sensing and detection module, and a stage 600. The horizontal ring structure 140 is rotatably mounted on the top of the support frame 400. The horizontal ring structure 140 has horizontal moving grooves 120, which are symmetrically distributed. Each horizontal moving groove 120 is slidably connected to a vertical ring-horizontal ring connector 200. The motion drive unit is mounted on the horizontal ring structure 140, the sensing and detection module is mounted on the vertical ring structure 210, and the stage 600 is fixed at the axis of the horizontal ring structure 140. The support frame 400 is fixedly mounted with a recessed flange 110, and a computer 500 and a spectrometer 300 are provided on one side of the support frame 400. One end of the vertical ring structure 210 is fixedly connected to the vertical ring-horizontal ring connector 200, and the other end of the vertical ring structure 210 is fixedly connected to the horizontal ring structure 140. The horizontal ring structure 140 provides the longitude direction movement trajectory, and the vertical ring structure 210 provides the dimensional direction movement trajectory. The vertical ring structure 210 is slidably engaged with the horizontal ring structure 140 through the vertical ring-horizontal ring connector 200. The motion drive unit drives the horizontal ring structure 140 to rotate and the sensing and detection module to move along the vertical ring structure 210. The vertical ring structure 210 can slide along the horizontal moving groove 120 via the vertical ring-horizontal ring connector 200, thereby achieving radial position adjustment along the horizontal ring structure 140. Among them, a moving part gear guide rail 220 is fixedly connected to the front end of the vertical ring structure 210; The moving part gear guide rail 220 is equipped with two moving connectors 240, which are symmetrically distributed on the left and right sides. The retainer 310 is fixedly connected to the motion connector 240 and can move circumferentially along the motion gear guide rail 220 of the vertical ring structure 210. The distance between the retainer 310 and the light carrier on the stage 700 can be adjusted by the telescopic guide rail 230. The motion drive unit includes a first motor 101, a second motor 100, a drive wheel 260, and a directional wheel 250. The second motor 100 is fixed to the horizontal ring structure 140 via a concave flange 110. The first motor 101 is fixedly connected to the corresponding motion connector 240. The drive wheel 260 is fixedly connected to the output shaft of the first motor 101. The directional wheel 250 is fixedly connected to the motion connector 240. The moving part gear guide rail 220 is integrally formed from a large gear and a gear groove; The drive wheels 260 are all meshed with the large gears on the moving part gear guide rail 220; There are eight directional wheels 250, and four directional wheels 250 are fixedly connected to the four rear corners of the motion connector 240. The four directional wheels 250 are symmetrically distributed, and all four directional wheels 250 are slidably connected to the wheel grooves on the moving part gear guide rail 220. Each motion connector 240 is fixedly connected to a telescopic guide rail 230, and a retainer 310 is slidably mounted on the telescopic guide rail 230. The sensing and detection module includes an excitation device 270 and a detection device 280, which are detachably mounted in a retainer 310. The detection device 280 is connected to the spectrometer 300 via signal transmission. The excitation device 270 is a laser exciter that can emit excitation light to the optical carrier, adapting to the detection requirements of non-self-emitting optical carriers; Motor 2 100 receives control signals from computer 500 and drives horizontal circular structure 140 to rotate and detection device 280 to move along vertical circular structure 210. The support frame 400 has a rectangular frame structure with four adjustable feet at the bottom. Both Motor 101 and Motor 200 use the HC-SFS102B servo motor. The excitation device 270 is of model MTA-Laser-405 / 520 / 635; The model selected for the detection device 280 is: LISUN-LP-01 constant temperature photometric probe; The model selected for the spectrometer 140 is LPCE-2; Implementation Method 1 (Self-Emitting Scenario of Photocarrier): The detection device 280 is assembled inside the retainer 310, and the self-luminous sample 700 is fixed on the stage 600. The computer 600 sends a control signal to the motor 100, driving the horizontal ring structure 140 to rotate and the retainer 310 to drive the detection device 280 to move in the full circumference along the vertical ring structure 210, so that the detection device 280 can cover the entire spatial angle of the sample 700. The detection device 280 collects the optical signals emitted by the sample 700 in real time, realizing the detection of the light intensity distribution of the sample 700 in the entire space.

[0024] Implementation Method 2 (Stimulated Reflection Scenario of Optical Carrier): Two sets of retainers 310 are mounted on the vertical ring structure 210. One set of retainers 310 is equipped with an excitation device 270, and the other set of retainers 310 is equipped with a detection device 280. The non-self-luminous sample 700 is fixed on the stage 600, and the angles of the two sets of retainers 310 are adjusted to preset positions. The excitation device 270 emits excitation light to the sample 700, and the detection device 280 receives the reflected light signal from the sample 700. By adjusting the relative angle of the two sets of retainers 310 and their positions along the telescopic guide rail 230, the intensity of the reflected light from the sample 700 at a specific angle can be accurately detected.

[0025] Implementation Method 3 (Scenario of excitation light on photocarrier): The detection device 280 is assembled inside the retainer 310. An external excitation light source emits excitation light onto the non-self-luminous sample 700 fixed on the stage 600, causing the sample 700 to generate a light emission signal. The computer 600 controls the horizontal ring structure 140 to rotate, and the retainer 310 drives the detection device 280 to move along the vertical ring structure 210. The detection device 280 collects the light emission signal generated by the sample 700, completing the full-space detection of the excitation light signal of the sample 700.

[0026] Working principle: By assembling different functional modules within the retainer 310, three different detection scenarios can be achieved. The general operating steps are as follows: Fix the sample 700 onto the stage 600 (the installation position of the stage 600 intersects the axis of the vertical ring structure 210 and the axis of the horizontal ring structure 140), ensuring that the sample 700 is in the detection center area of ​​the device; manually push the vertical ring-horizontal ring connector 200 to drive the vertical ring structure 210 to slide along the radial direction of the horizontal ring structure 140 (i.e., the extension direction of the horizontal moving groove 120), adjusting the vertical ring. The horizontal position of structure 210 ensures precise alignment of the initial detection position of sample 700 with that of detection device 280. Computer 600 sends control signals to motor 100, driving horizontal annular structure 140 to rotate around its own axis. Holder 310 moves detection device 280 along the circumference of vertical annular structure 210. Simultaneously, holder 310 can slide along telescopic guide rail 230 to adjust the distance between detection device 280 and sample 700. Finally, detection device 280 collects signals and transmits them to spectrometer 300, where computer 600 performs real-time data analysis and storage.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
