Description

Technical Field

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

[0002] Current LED light testing methods mostly employ single-point illumination detection, which can only test LEDs of a single style or with a fixed lead pitch. This fails to meet the requirements for simultaneous multi-unit testing, color difference comparison, and compatibility with LEDs of different sizes and lead pitches. Especially for surface-mount LEDs, traditional devices lack flexible contact designs, making it difficult to adapt to components of different thicknesses or sizes, resulting in low testing efficiency and limited applicability. Furthermore, the fixed socket spacing in existing technologies cannot be flexibly adjusted to accommodate diverse LED specifications, further limiting the practicality and automation integration potential of the testing devices. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0034] Please refer to Figure 1 and Figure 2 This embodiment provides an LED light detection device, which integrates a base 1, a top cover 2, an adjustable slider 3, an adjusting screw 4, a pressure plate 5, a pressure plate screw 6, a negative power supply socket group 7, a positive power supply socket group 8, a socket fixing seat 9, a positive contact 10, a negative contact 11, and a power supply battery 12.

[0035] The base 1 has a male buckle 1.1 and a retaining wall 1.2; the top cover 2 has a cavity 1 2.1 (through hole structure), a cavity 2.2, a patch test slot 2.3, a female buckle 2.4 and a screw countersunk hole 2.5; the pitch slider 3 has a pitch groove 3.1 and a threaded hole 3.2; the pressure plate 5 has an adjustment through hole 5.1; the negative power supply socket 7 has a negative series wire 7.1 and a negative socket folded edge 7.2; the positive power supply socket 8 has a positive series wire 8.1 and a positive socket folded edge 8.2; the socket fixing seat 9 has a negative cavity 9.1, a positive cavity 9.2, a negative side folded edge slot 9.3, a pitch drive column 9.4 and a positive side folded edge slot 9.5.

[0036] like Figure 3 As shown, the negative power supply socket group 7 and the positive power supply socket group 8 are respectively inserted into the socket fixing base 9 from both ends of the socket fixing base 9, and are respectively assembled into the negative cavity 9.1 and the positive cavity 9.2. The pin sockets of the power supply sockets face outwards from the upper cover 2 to facilitate the insertion of the pins of the plug-in LED. At this time, the negative socket folded edge 7.2 is fastened into the negative side folded edge slot 9.3, and the positive socket folded edge 8.2 is fastened into the positive side folded edge slot 9.5, thereby fixing the sockets to prevent them from shifting.

[0037] The power supply battery 12 is snapped between the positive contact 10 and the negative contact 11, and is connected in series with the negative power supply socket group 7 and the positive power supply socket group 8 by the negative series wire 7.1 and the positive series wire 8.1, respectively. The pitch adjustment slider 3 is placed in the sliding cavity formed by the base 1 and the upper cover 2. At this time, the pitch change drive column 9.4 of the socket fixing seat 9 is fitted into the pitch change slot 3.1 one by one.

[0038] The insert fixing seat 9 is located in cavity 2.1 of the upper cover 2. The positive electrode contact 10, the negative electrode contact 11, and the power supply battery 12 are assembled in cavity 2.2 of the upper cover 2. Cavity 2.2 is connected to the surface mount testing slot 2.3, so that the opposite surfaces of the positive electrode contact 10 and the negative electrode contact 11 are located in the surface mount testing slot 2.3, that is, the positive electrode contact 10 and the negative electrode contact 11 are located in the surface mount testing slot 2.3, which facilitates the testing of surface mount LEDs. The surface mount testing slot 2.3 is a strip-shaped slot structure with chamfered surfaces at both ends to guide the surface mount LED to slide into the contact gap. The base 1 is fastened into the upper cover 2 through the cooperation of the male buckle 1.1 and the female buckle 2.4. The adjusting screw 4 is inserted into the upper cover 2 through the screw countersunk hole 2.5 and locked in the threaded hole 3.2, thus realizing the threaded connection of the adjustable slider 3. Then, the pressure plate 5 is locked onto the upper cover 2 by the pressure plate screw 6 to prevent the adjusting screw 4 from falling off.

[0039] Combination Figure 4 and Figure 5 As shown, during use, an adjusting wrench is inserted through the adjusting through-hole 5.1 and locked into the wrench insertion hole at the rear end of the adjusting screw 4, driving the adjusting screw 4 to rotate. This causes the pitch adjusting slider 3 to move back and forth, driving the pitch adjusting drive column 9.4 through the pitch changing slot 3.1 to complete the dispersion or convergence action. This achieves the distance adjustment of the negative power supply socket group 7, the positive power supply socket group 8, and the socket fixing seat 9 in the cavity 2.1 of the upper cover 2, realizing dispersion or convergence, thereby matching the detection of LED lights with different pin spacings. The linkage and equidistant adjustment of the multiple socket fixing seats 9 can realize the simultaneous power supply detection of multiple LED lights and the color difference comparison between LED lights.

[0040] In addition to the socket module for testing adjustable-pitch LED devices, the device also includes a surface mount component test slot 2.3, and positive and negative contacts 10 and 11 with flexible metal bending properties, as shown in [reference needed]. Figure 4 As shown, the surface mount LED is picked up with tweezers and slid into the gap between the positive contact 10 and the negative contact 11 from the surface mount component test slot 2.3, with both ends contacting and bonding the positive contact 10 and the negative contact 11 respectively, to achieve power supply and lighting test. The good resilience of the positive and negative contacts can be adapted to the testing of surface mount LEDs of different sizes and specifications.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
