Description

Technical Field

[0001] This utility model relates to the field of LED testing technology, specifically to an LED light strip testing device. Background Technology

[0002] LED light strips are strip-shaped light-emitting structures formed by assembling multiple LED components. They are widely used in light-emitting fields such as LCD displays. Currently, backlight modules of LCD displays are experiencing issues such as uneven brightness and hotspots on the incident light side. It is necessary to perform optical data measurements on individual LEDs of the LED light strip to analyze whether the issue is caused by a defective individual LED or by the supplier mixing in LEDs of other specifications.

[0003] In current technology, before performing optical data measurements on individual LEDs, it is mostly necessary for personnel to manually desolder the individual LEDs from the LED strip, and then use an integrating sphere to measure the optical data of the individual LEDs. However, this measurement method involves desoldering the LED strip, which is a destructive experiment, time-consuming, labor-intensive, and wasteful of samples. Utility Model Content

[0004] The purpose of this invention is to provide an LED light strip testing device that eliminates the need for individual desoldering and testing of multiple LED components during LED light strip testing, thereby reducing sample waste.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an LED light strip detection device, including an integrating sphere, an adjustment mechanism at the bottom of the integrating sphere, and a light shield inserted through it, and also includes a detection mechanism;

[0006] The detection mechanism includes a fixed base, a sliding base, a sliding plate, an upper clamping plate, a lower clamping plate, an adjusting plate, a pulling plate, and a spectrometer. The fixed base is detachably connected to the integrating sphere and is located on top of the integrating sphere. The sliding base is integrally formed with the fixed base and is located on the fixed base. The sliding plate can slide vertically on the sliding base. An LED light strip is provided in the mounting groove at the bottom of the sliding plate. Multiple LED elements are arranged in a row on the LED light strip. The LED light strip is fixed by bolts through the upper and lower clamping plates. After installation, the end face of the multiple LED elements near the spectrometer is lower than the depth of the mounting groove of the sliding plate. The adjusting plate is slidably connected to the top end face of the sliding base and the sliding plate and passes through the sliding plate. The pulling plate is integrally formed with the adjusting plate and is located on one side of the adjusting plate. The spectrometer is located on the left side of the integrating sphere, and its probe can be opposite to the LED elements.

[0007] The mounting slot on the sliding plate for installing the LED light strip is vertically connected and has a cable hole.

[0008] The detection mechanism further includes a T-shaped pin, which is slidably connected to the adjusting plate and threadedly connected to the slide block.

[0009] The adjustment mechanism includes an adjustment seat and a connecting seat. The adjustment seat is detachably connected to the integrating sphere and is disposed at the bottom of the integrating sphere. The connecting seat is connected to the adjustment seat through a connector and is located at the bottom of the adjustment seat.

[0010] The spectroscopic device includes a spectrometer body and a spectrometer probe. The spectrometer body is located on the left side of the integrating sphere. The spectrometer probe is electrically connected to the spectrometer body and detachably connected to the integrating sphere, and is positioned opposite to the LED element.

[0011] The detection mechanism further includes a gripping rod, which is threadedly connected to the sliding plate and located on the top of the sliding plate away from the cable hole. The surface of the gripping rod is provided with an anti-slip coating.

[0012] This utility model discloses an LED strip testing device. During LED strip testing, the LED strip is first fixed to the bottom of a sliding plate using upper and lower clamping plates and bolts. Then, the sliding plate is vertically slidably installed on a sliding base, with an adjusting plate engaging with the groove at the lowest point of the sliding plate. This aligns the LED element with the probe of the spectral device. Next, a light-shielding plate is slidably inserted, with a single detection hole on the light-shielding plate corresponding exclusively to the LED element during operation. Optical testing can then be performed using the spectral device to determine whether each individual LED element on the LED strip meets optical requirements. Before testing, manual desoldering of the LED elements on the LED strip is unnecessary, thus eliminating the need for individual desoldering and testing of multiple LED elements during LED strip testing, reducing sample waste.

Detailed Implementation

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1:

[0022] like Figures 1 to 4 The diagram shows that... Figure 1 This is a schematic diagram of the overall structure of the LED light strip testing equipment. Figure 2 This is a schematic diagram of the installation of the light-shielding plate 102. Figure 3 This is a cross-sectional view of integrating sphere 101. Figure 4 This is a schematic diagram of the sliding plate 105. This utility model provides an LED light strip testing device: including an integrating sphere 101, an adjustment mechanism, a light-shielding plate 102, and a testing mechanism. The testing mechanism includes a fixed base 103, a sliding base 104, a sliding plate 105, an upper clamping plate 106, a lower clamping plate 107, an adjustment plate 108, a pull plate 109, a T-pin 112, and a spectrometer. The adjustment mechanism includes an adjustment base 113 and a connecting base 114. The spectrometer includes a spectrometer body 116 and a spectrometer probe 117. This solution eliminates the need for individual desoldering and testing of multiple LED components 111 during LED light strip 110 testing, thus reducing sample waste.

[0023] In this embodiment, an adjustment mechanism is provided at the bottom of the integrating sphere 101, and a light-shielding plate 102 is inserted through it. The adjustment mechanism is used to adjust the working height of the integrating sphere 101 and fix it on the test stage. The light-shielding plate 102 is a rectangular plate with a detection port corresponding to the LED element 111. It is limited by an L-shaped support arm on one side of the integrating sphere 101, so as to ensure that the detection port can fully expose the tested LED element 111 after it is installed in place, which is beneficial to the testing of the spectral device.

[0024] The fixed base 103 is detachably connected to the integrating sphere 101 and is located on top of the integrating sphere 101. The sliding base 104 is integrally formed with the fixed base 103 and is located on the fixed base 103. The sliding plate 105 can slide vertically on the sliding base 104. An LED light strip 110 is provided in the mounting groove at the bottom of the sliding plate 105. Multiple LED elements 111 are arranged in a row on the LED light strip 110. The LED light strip 110 is fixed by bolts through the upper clamping plate 106 and the lower clamping plate 107. After installation, the end face of the multiple LED elements 111 near the spectral device is lower than the depth of the mounting groove of the sliding plate 105. The adjusting plate 108 is slidably connected to the top end face of the sliding base 104 and the sliding plate 105 respectively, and passes through the sliding plate 105. The pull plate 109 is integrally formed with the adjusting plate 108 and is located on one side of the adjusting plate 108. The spectral device is set on the... The integrating sphere 101 is positioned to the left, and its probe is positioned opposite the LED element 111. The fixing base 103 is fixed with bolts. The sliding base 104 is integrally formed with the fixing base 103 and is provided with a vertical through rectangular groove for the sliding plate 105 to slide. The bottom of the sliding plate 105 is provided with a mounting groove for the LED light strip 110 to be installed. The mounting groove is provided with slots on the upper clamping plate 106 and the lower clamping plate 107 on both sides. The upper clamping plate 106 and the lower clamping plate 107 are fixed with countersunk bolts. The sliding plate 105 is provided with multiple through grooves according to the spacing of the multiple LED elements 111 to cooperate with the adjusting plate 108. The adjusting plate 108 is used for vertical position adjustment of the sliding plate 105, thereby facilitating the position adjustment of the LED element 111. The pull plate 109 is integrally formed on one side of the adjusting plate 108 to form an L-shaped structure, which facilitates the installation and removal of the adjusting plate 108. The spectral device is used for testing.

[0025] The sliding plate 105 has a vertically connected mounting slot for mounting the LED light strip 110, which includes a cable hole. The cable hole facilitates the installation of the power cable for the LED light strip 110, which passes through from bottom to top and connects to an external power source.

[0026] Secondly, the T-pin 112 is slidably connected to the adjusting plate 108 and threadedly connected to the slide block 104. The adjusting plate 108 has a through hole on the side away from the pull plate 109. When the adjusting plate 108 is installed, its limiting rectangular portion abuts against the sliding plate 105. At this time, the through hole aligns with the threaded hole on the slide block 104. Then, installing the T-pin 112 maintains the stable position of the adjusting plate 108. Subsequent adjustments can be made simply by removing the T-pin 112 and sliding the adjusting plate 108 out.

[0027] Then, the adjusting seat 113 is detachably connected to the integrating sphere 101 and is located at the bottom of the integrating sphere 101; the connecting seat 114 is connected to the adjusting seat 113 via the connecting piece 115 and is located at the bottom of the adjusting seat 113. The top disc of the adjusting seat 113 is fixed to the bottom of the integrating sphere 101 by bolts, and a rectangular cavity is vertically provided at its rectangular end. Multiple adjusting holes are provided through the side walls on both sides of the rectangular cavity. The top of the connecting seat 114 is provided with a single through hole. The connecting piece 115 consists of a T-shaped screw and a nut. The bottom disc of the connecting seat 114 is provided with mounting holes to facilitate fixing it to the test bench with bolts.

[0028] Finally, the spectrometer body 116 is disposed on the left side of the integrating sphere 101; the spectrometer probe 117 is electrically connected to the spectrometer body 116 and detachably connected to the integrating sphere 101, and is disposed opposite to the LED element 111. The spectrometer body 116 can be directly disposed on the test stage, and the spectrometer probe 117, which is electrically connected to it for testing, is fixed on the integrating sphere 101.

[0029] When using this invention to eliminate the need for individual desoldering and testing of multiple LED elements 111 during LED strip 110 testing, thus reducing sample waste, the LED strip 110 is first fixed to the bottom of the sliding plate 105 using the upper clamping plate 106 and the lower clamping plate 107 with bolts. Then, the sliding plate 105 is vertically slidably mounted on the slide block 104, with the adjusting plate 108 engaging with the groove at the lowest point of the sliding plate 105, aligning the bottommost LED element 111 with the spectrometer probe 117. Next, the light-shielding plate 102 is slidably inserted. Each detection hole on the light-shielding plate 102 corresponds exclusively to one LED element 111 during operation, ensuring that the bottommost LED element 111 on the LED strip 110 is aligned with the detection port on the light-shielding plate 102. In addition, when the light-shielding plate 102 is installed, it can slide and contact the end face of the sliding plate 105 near the spectrometer probe 117. Then, the power supply of the LED light strip 110 is turned on, and optical testing can be performed through the spectrometer device to determine whether the individual LED elements 111 on the LED light strip 110 meet the optical requirements. Before the test, it is not necessary to manually desolder the LED elements 111 on the LED light strip 110. Subsequently, the position of the LED elements 111 is adjusted by the cooperation of the adjusting plate 108 and the through grooves at different positions set from bottom to top on the sliding plate 105, so as to realize the testing of all individual LED elements 111 on the LED light strip 110. In this way, it is possible to realize the testing of multiple LED elements 111 individually after desoldering when testing the LED light strip 110, which helps to reduce sample waste.

Based on the first embodiment, this utility model provides an LED light strip testing device. The testing mechanism further includes a gripping rod 201, which is threadedly connected to the sliding plate 105 and located on the top of the sliding plate 105 and away from the cable hole. The surface of the gripping rod 201 is provided with an anti-slip coating.

[0032] In this embodiment, the external threaded end of the gripping rod 201 is directly mounted on the sliding plate 105, and an anti-slip coating is provided on its surface. The gripping rod 201 makes it easier to install or adjust the position of the sliding plate 105.
