[0002] Light-emitting diodes, or LEDs for short, are a common type of light-emitting device. They emit light by releasing energy through the recombination of electrons and holes, and can efficiently convert electrical energy into light energy. They have a wide range of applications in modern society, such as lighting, flat panel displays, and medical devices.

[0003] Traditionally, when testing the brightness of LEDs, the tester must hold the brightness meter upright, align it with the LED, and manually adjust the distance between the meter and the LED. Because the entire process relies on manual operation, it is difficult to precisely control the distance between the meter and the LED during the test, leading to significant errors in the test data and affecting the reliability of the test results.

[0004] Therefore, there is a need to provide a light-emitting diode brightness detection device. Utility Model Content

[0018] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0019] Example: A light-emitting diode brightness detection device, please see below. Figs. 1 to 3As shown, the device includes a mounting cabinet 1, a cabinet door 2, a gantry frame 3, a motor 4, a threaded rod 5, a horizontal plate 6, a light sensor 7, scale lines 8, a second motor 9, a gear set 10, a rotating disk 11, a connecting plate 12, a fixing plate 13, a cylinder 14, a double-acting screw 15, a sliding plate 16, a spring 17, a clamp 18, a support plate 19, a telescopic rod 20, and a cabinet cover 21. The mounting cabinet 1 serves as the main support structure of the entire testing device, providing a platform for the installation of other components. The front of the mounting cabinet 1 is symmetrically connected to the cabinet door 2, which is used to close or open the mounting cabinet 1 for easy operation and maintenance of the internal components. A gantry frame 3 is horizontally connected to the top of the mounting cabinet 1. A motor 4 is vertically mounted on the lower left side of the inner part of the gantry frame 3. The output of motor 4... A threaded rod 5 is connected to the shaft, and the threaded rod 5 is rotatably connected to the left side of the inside of the gantry frame 3. A guide rod is vertically connected to the right side of the inside of the gantry frame 3. A horizontal plate 6 is slidably connected inside the gantry frame 3. The left side of the horizontal plate 6 is threadedly connected to the threaded rod 5, and the right side of the horizontal plate 6 is slidably connected to the guide rod. A light sensor 7 is embedded in the middle of the horizontal plate 6. The light sensor 7 is used to detect the brightness of the light-emitting diode and convert the light signal into an electrical signal to provide a basis for subsequent data processing and analysis. A motor 4 serves as a power source, driving the threaded rod 5 to rotate, providing power for the up and down movement of the horizontal plate 6 and the light sensor 7, realizing the height adjustment of the light sensor 7 to adapt to the detection needs of light-emitting diodes of different heights. A scale line 8 is vertically connected to the front right side of the gantry frame 3. By observing the position of the horizontal plate 6 corresponding to the scale line 8, the height of the light sensor 7 can be intuitively understood, facilitating precise adjustment of the light sensor 7's position. A second motor 9 is vertically mounted upwards on the bottom left side inside the mounting cabinet 1. A mounting slot is provided in the upper part of the mounting cabinet 1, and a gear set 10 is connected within the mounting slot. The gear set 10 consists of two small gears and a large gear. The small gears are connected to the output shaft of the second motor 9, and the large gear meshes with the small gears. A rotating disk 11 is connected to the top of the large gear. The rotating disk 11 is located in the upper part of the mounting cabinet 1. The second motor 9 serves as the power source, driving the gear set 10 to rotate, providing power for the rotation of the rotating disk 11. Driven by the gear set 10, the rotating disk 11 rotates, causing the components connected to it to rotate, thus realizing the rotation of the light-emitting diode. The angle is adjusted to detect the brightness of the LED from different angles. A connecting plate 12 is connected to the rear top of the rotating disk 11. A fixed plate 13 is rotatably connected to the upper part of the connecting plate 12. Cylinders 14 are vertically mounted symmetrically upwards on the front top of the rotating disk 11. The piston rods of the two cylinders 14 are connected to the bottom of the fixed plate 13. The extension and retraction of the piston rods of the cylinders 14 drive the fixed plate 13 to rotate around the connecting plate 12, thereby adjusting the angle of the fixed plate 13 and thus adjusting the detection angle of the LED. A sliding groove is horizontally opened at the center of the top of the fixed plate 13. Sliding plates 16 are symmetrically slidably connected inside the sliding groove. A bidirectional screw 15 is threaded between the middle parts of the sliding plates 16. Both sliding plates 16 have horizontally opened sliding grooves inside.Clamps 18 are elastically connected to the sliding grooves of the sliding plate 16 via springs 17. The inner surface of each clamp 18 is provided with a soft pad to increase the friction between the LED and the clamp 18, providing an anti-slip function. The clamps 18 are used to directly hold the LED, ensuring its stability during the testing process. The springs 17 provide elastic cushioning for the clamps 18, allowing them to automatically adjust the clamping force according to the size of the LED. A support plate 19 is connected to the front top of the rotating disk 11. The support plate 19 is located at... Between the two cylinders 14, the support plate 19 provides bottom support for the fixed plate 13, preventing the LEDs from drooping or swaying due to gravity during detection, thus affecting detection accuracy. Telescopic rods 20 are connected to the left front and right rear sides of the gantry 3, with a cabinet cover 21 connected to the other end of each rod. The telescopic rods 20 enable the cabinet cover 21 to extend and retract, providing power and guidance for its opening and closing. When closed, the cabinet cover 21 completely covers the installation cabinet 1, protecting its internal components.

[0020] When the LED brightness detection device is needed, the operator first opens the front door 2 of the mounting cabinet 1 to access the internal components. Then, by controlling the telescopic rod 20, the cabinet cover 21 connected to the gantry 3 is opened to both sides, fully exposing the mounting cabinet 1 and preparing for the subsequent placement and fixing of the LEDs.

[0021] Rotating the bidirectional screw 15 will cause the two sliding plates 16 to slide in opposite directions within the groove at the top of the fixed plate 13, increasing the distance between the two sliding plates 16 and leaving enough space for placing the light-emitting diode.

[0022] The LED to be tested is placed on the support plate 19 on the fixed plate 13. The support plate 19 provides bottom support for the LED to prevent it from sagging or shaking due to gravity during the testing process.

[0023] Rotating the bidirectional screw 15 in the opposite direction causes the two sliding plates 16 to slide towards each other, bringing the clamp 18 closer to the LED. Under the elastic buffering action of the spring 17, the clamp 18 can automatically adjust the clamping force according to the size of the LED, ensuring that the LED is clamped while avoiding damage to the LED due to excessive clamping.

[0024] Start motor 4, and the output shaft of motor 4 drives the threaded rod 5 to rotate. Since the left side of the horizontal plate 6 is connected to the threaded rod 5 by a thread, and the right side is slidably connected to the guide rod inside the gantry frame 3, the horizontal plate 6 will move up and down along the gantry frame 3 under the drive of the threaded rod 5.

[0025] By observing the position of the horizontal plate 6 corresponding to the scale line 8 on the right front side of the gantry 3, the operator can intuitively understand the height of the light sensor 7, and precisely adjust the height of the light sensor 7 according to the height of the light-emitting diode to be tested, so that the light sensor 7 is in a suitable detection position.

[0026] When cylinder 14 is activated, its piston rod extends or retracts, causing the fixed plate 13 to rotate around the connecting plate 12. By controlling the degree of extension or retraction of the piston rod of cylinder 14, the angle of the fixed plate 13 is adjusted, thereby changing the detection angle of the light-emitting diode (LED) to detect its brightness from different angles.

[0027] In addition, motor 9 can be started, which drives the small gear in gear set 10 to rotate. The small gear meshes with the large gear, which in turn drives the rotating disk 11 connected to the top of the large gear to rotate. The rotating disk 11 drives the connecting plate 12, fixing plate 13, light-emitting diodes and other components connected to it to rotate together, further realizing the adjustment of the angle of the light-emitting diodes and meeting the needs of multi-angle detection.

[0028] Once the height of the light sensor 7 and the angle of the LED are adjusted to the appropriate positions, the LED is turned on, causing it to emit light. The light sensor 7 then begins to detect the brightness of the LED and converts the received light signal into an electrical signal.

[0029] The electrical signal output by the light sensor 7 is transmitted to the data processing and analysis device to record the detection data. The data is then analyzed and processed as needed to obtain the brightness detection result of the light-emitting diode.

[0030] After the test is completed, turn off the LED, rotate the bidirectional screw 15 in the opposite direction to make the two sliding plates 16 slide in opposite directions, release the clamp 18, take out the LED that has been tested, control motor 4 and motor 9 to reset the horizontal plate 6, rotating disk 11 and other components to their initial positions, and prepare for the next test.

[0031] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
