Description

Technical Field

[0001] This utility model mainly relates to the technical field of semiconductor testing, specifically a brightness testing device for light-emitting diode production. Background Technology

[0002] The purpose of brightness testing in LED production is to accurately obtain the brightness value of LEDs through professional instruments, thereby evaluating whether their lighting effect meets the expected design requirements. In LED production, color temperature measurement helps ensure that the product provides a comfortable lighting experience in different application scenarios. In the LED production process, accurate brightness testing is one of the key steps to ensure product quality. Traditional brightness testing methods often suffer from low testing efficiency and insufficient testing accuracy, making it difficult to meet the needs of large-scale production. Therefore, developing an efficient and accurate LED production brightness testing device is particularly important.

[0003] According to application number 202222439186.3, a brightness testing device for LED production is provided. The device fixes the brightness tester in place within a frame. A motor drives a lead screw to rotate, causing a moving plate to move up and down, thus moving the diode and adjusting the distance between the diode and the tester. A side plate allows a test block to be bolted to the moving plate for easy assembly and disassembly. A threaded rod and a pressure block, when rotated, press the pressure block against the side wall of the diode, fixing it in place and preventing positional movement. A scale allows operators to observe the scale readings to determine the distance between the diode and the brightness tester.

[0004] The aforementioned document describes a height adjustment structure that can replace manual intervention to precisely adjust the distance between the diode and the tester, thereby accurately testing the diode's brightness performance at different distances. However, the adjustable distance is relatively short, and the device occupies a large area. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a brightness testing device for LED production, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A brightness testing device for LED production includes a power supply base, C-shaped frames at both ends of the top of the power supply base, multiple light guide slots mounted side by side on the top of the power supply base, multiple polarizing tubes connected sequentially to both ends of the light guide slots, a detection base at one end of the first light guide slot, a guide rod in the middle of the two C-shaped frames, a detection tube slidably disposed below the guide rod, and a brightness detector disposed inside the detection tube.

[0008] Preferably, the light guide groove includes a flip cover at the top and lamp arrays at both ends inside the light guide groove.

[0009] Preferably, the polarizing tube is trapezoidal, including a rotating disk connected to one end of the light guide groove, and two polarizing mirrors symmetrically arranged at the corner points inside the polarizing tube.

[0010] Preferably, the detection base includes a hinge column and a rotating power supply head disposed inside the hinge column.

[0011] Preferably, the detection tube is hollow on both sides and includes a sliding cylinder at the top and sleeved outside the guide rod, a strip groove on the side, two rubber sheets inside the strip groove, and a scale line at the top of the strip groove.

[0012] Preferably, the brightness detector includes a mounting slider that is slidably disposed inside the detection tube, photoelectric probes disposed on both sides of the mounting slider, a toggle sleeve disposed at one end of the mounting slider, and a pointer disposed on the top of the toggle sleeve.

[0013] Preferably, the power supply base includes a control power supply located on one side of the top, and multiple wires connecting the control power supply to various electrical devices.

[0014] In summary, this technical solution has the following main advantages:

[0015] In this embodiment, the flip cover at the top of the light guide groove can be opened or closed to simulate outdoor light interference or provide varying lighting conditions. When the flip cover is open, outdoor light can enter the system, simulating the brightness change of the LED under outdoor light interference. When the flip cover is closed, the lamp array inside the light guide groove 12 can be turned on with adjusted brightness according to the settings, providing different light interference conditions for the LED. This design allows the device to more comprehensively evaluate the performance of the LED under different lighting conditions.

[0016] To achieve long-distance detection position adjustment, the detection tube can slide along the guide rod to connect with different light guide slots and adjust the distance for testing. At the same time, by moving the toggle sleeve, the position of the mounting slider inside the detection tube can be adjusted to further achieve long-distance detection position adjustment. This design allows the device to flexibly adapt to LEDs of different lengths or testing needs, improving the accuracy and reliability of the test. Attached Figure Description

When the flip cover 121 on the top of the light guide 12 is closed, the lamp array 122 inside the light guide 12 is turned on according to the set brightness adjustment. These lamp arrays 122 are used to provide varying lighting conditions for the light-emitting diode during the test. The rotating power supply head 142 can provide power to the light-emitting diode. The hinge column 141 can easily install the rotating power supply head 142 in a vertical state. After rotating it to a straight position, the light-emitting diode can enter the light guide 12.

[0028] Please refer to the attached document carefully.

The detection tube 16 is slidably located below the guide rod 15 and can move along the guide rod 15 to adjust the distance for testing by aligning with different light guide slots 12. A strip groove 162 is provided on the side of the detection tube 16. The position of the mounting slider 171 can be adjusted by moving the toggle sleeve 173. Two rubber sheets 163 are provided inside the strip groove 162. These rubber sheets 163 can seal off other areas of the strip groove 162 to prevent external light from entering. A scale line 164 is provided at the top of the strip groove 162 to indicate the sliding position of the detection tube 16. By adjusting the alignment of the mounting slider 171 and the detection tube 16, long-distance detection position adjustment can be achieved.
