[0002] LED downlights, as a type of high-efficiency indoor lighting fixture, are widely used in various commercial and residential environments. During their manufacturing process, luminous efficacy is one of the core indicators for measuring their performance and quality. Therefore, conducting rapid and accurate luminous efficacy testing on each LED downlight before it leaves the factory is a crucial step in ensuring product quality.

[0003] Currently, the luminous efficacy testing of LED downlights on the production line is generally carried out manually. This means that the operator places the lit downlights into a fixed dark box testing station, reads the test data, and then manually sorts the products into the qualified or unqualified areas based on the results. The efficiency of this manual testing and sorting method is directly limited by the operator's working speed. Utility Model Content

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] An LED downlight effect testing device includes a belt conveyor 1, with several placement platforms 2 evenly distributed on the outside of the belt of the belt conveyor 1. Each placement platform 2 has an arc-shaped support groove at its top. A dark box 3 is fixedly connected to the top center of the belt conveyor 1. Opening and closing mechanisms are provided on both sides of the dark box 3. Each opening and closing mechanism includes a conveying channel 5 extending through both ends of the dark box 3, and baffles 6 located outside the conveying channels 5. A frame 7 is fixedly connected to the top center of the dark box 3. An electric push rod 8 is fixedly connected to the top center of the frame 7. A lifting frame 9 is fixedly connected between the top centers of the two baffles 6. The output shaft of the electric push rod 8 is fixedly connected to the lifting frame 9. At the top center of the lowering frame 9, vertical dovetail grooves 10 are provided on both sides of the dark box 3 located on the outside of the conveying channel 5. Dovetail slide strips 11 that slide in cooperation with the dovetail grooves 10 are fixedly connected to both sides of the baffle 6 near the conveying channel 5. The detection box 4 is fixedly connected to one side of the dark box 3. The detection box 4 is equipped with a detection mechanism, which includes a light intensity sensor 12 fixedly connected to the bottom right side of the detection box 4. The detection end of the light intensity sensor 12 extends into the interior of the detection box 4. A circular hole 13 is provided between the bottom of the detection box 4 and the dark box 3. The circular hole 13 and the detection end of the light intensity sensor 12 are on the same horizontal line. The testing mechanism also includes an electric push rod 14 fixedly connected to the outside of the dark box 3 on the side away from the testing box 4. A push plate 15, which is on the same horizontal line as the circular hole 13, is fixedly connected to the output shaft end of the electric push rod 14 and the end located inside the dark box 3. A vertical suspension bracket 16 is fixedly connected to the inner top wall of the right side of the dark box 3. An electric push rod 17 is fixedly connected to the outside of the suspension bracket 16 near the electric push rod 14. A vertical positioning plate 18 is fixedly connected to the output shaft of the electric push rod 17. A positioning hole 19, which is on the same horizontal line as the circular hole 13, is provided on the positioning plate 18. The center of the positioning hole 19 and the center of the circular hole 13 are... When the center of the device and the center of the arc-shaped support groove of the device 2 are located in the middle of the inner side of the dark box 3, the three are on the same horizontal axis. The upper right side of the belt conveyor 1 is fixedly connected to the mounting bracket 20. The back of the mounting bracket 20 is fixedly connected to the electric push rod 21. The output shaft of the electric push rod 21 is fixedly connected to the push disk 22. When any device 2 moves to the middle of the inner side of the dark box 3, the center of the device 2 on the right side of the device 2 and the center of the electric push rod 21 are on the same horizontal line. The upper right side of the detection box 4 is fixedly connected to the PLC controller 23. The illuminance sensor 12 is electrically connected to the electric push rod 21 through the PLC controller 23.

[0026] In this embodiment, the automatic conveying and luminous efficacy detection of LED downlights in a closed darkroom environment is achieved through the combined use of belt conveyor 1, darkroom 3, baffle 6 and illuminance sensor 12, replacing traditional manual operation and solving the problem of low detection efficiency caused by reliance on manual operation in the existing technology.

[0027] Based on the detection results of the illuminance sensor 12, the PLC controller 23 automatically controls the movement of the electric push rod 21 and the push plate 22, realizing the automatic identification and sorting of qualified and unqualified products, and solving the production efficiency bottleneck problem of the existing technology that requires manual judgment and sorting.

[0028] Working principle: The belt conveyor 1 starts and drives several placement platforms 2 outside its belt to perform step-by-step conveying. When one of the placement platforms 2 carries the LED downlight to be tested, which is already in the open state, and moves to the middle of the inner side of the dark chamber 3, the central axis of the downlight is automatically aligned with the center of the positioning hole 19 and the center of the circular hole 13. At this time, the electric push rod 8 is activated and the two baffles 6 are lowered synchronously through the lifting frame 9. The baffles 6 slide downward along the dovetail slide groove 10 and the dovetail slide bar 11, thereby closing the conveying channels 5 on both sides of the dark chamber 3 to form a dark chamber environment. Then, the electric push rod 14 is activated and pushes the downlight through the push plate 15, so that the end of its lamp head abuts against the positioning plate 18. The light emitted by the downlight passes through the positioning hole 19 on the positioning plate 18 and the circular hole 13 between the dark chamber 3 and the detection box 4 in sequence and enters the interior of the detection box 4. It is received and measured by the illuminance sensor 12 fixed at the bottom right side of the detection box 4. The illuminance sensor 12 converts the collected light signal into an electrical signal and transmits it to the PLC controller 23. When the luminous efficacy data is processed by the PLC controller 23 and deemed qualified, the PLC controller 23 first controls the electric push rod 17 to retract the positioning plate 18 to reset the downlight, and then controls the electric push rod 8 to raise the baffle 6 and start the belt conveyor 1 to step one station, so that the next downlight enters the dark box 3 and the qualified downlight is transported to the outside. When the luminous efficacy data is deemed unqualified, the PLC controller 23 also first controls the electric push rod 17 and the electric push rod 8 to perform the reset and start actions, and controls the belt conveyor 1 to step one station. When the unqualified downlight is transported to the specific station outside, the PLC controller 23 then controls the electric push rod 21 to start, and pushes the unqualified downlight out of the push plate 22 and sends it into the collection box placed in advance on one side, thereby completing the automatic sorting of qualified and unqualified products.

[0029] It should be noted that the PLC controller 23 is electrically connected to the belt conveyor 1, electric push rod 21, electric push rod 4 8, electric push rod 3 17, electric push rod 14 and light intensity sensor 12, and executes the above control process based on a preset program.
