Problems solved by technology
Most of the existing photoelectric performance test fixtures for individual LED array light sources on the market are special fixtures for specific instruments, which cannot be used universally for other test equipment; moreover, these fixtures generally cannot change the test angle and distance of the LED light source under test, and are inconvenient to install. There are also various special requirements for the shape and size of the LED bracket
At the same time, the existing fixtures are mostly used for the photoelectric performance test of single or low-power LED light sources, and the test fixtures in the form of high-power and LED arrays are still in the state of self-designed and developed

Embodiment Construction
[0027] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that in the drawings or description of the specification, similar or identical parts use the same drawing numbers. The implementations not shown or described in the drawings are those known to those of ordinary skill in the art. In addition, although this article may provide an example of a parameter containing a specific value, it should be understood that the parameter does not need to be exactly equal to the corresponding value, but can be approximated to the corresponding value within acceptable error tolerances or design constraints. The directional terms mentioned in the embodiments, such as "upper", "lower", "front", "rear", "left", "right", etc., are only directions with reference to the draw...

The invention provides a clamp and a clamp assembly for testing LED array light source properties. The clamp comprises a bottom plate 10, a substrate 30 and a variable-angle connection rod 20. The variable-angle connection rod 20 comprises a first connection rod 20a and a second connection rod 20b, wherein the first connection rod 20a and the second connection rod 20b are arranged together in a cut-screwing mode. The top of the first connection rod 20a and the bottom of the second connection rod 20b are connected with the substrate 30 and the bottom plate 10 respectively, and one of the first connection rod 20a and the second connection rod 20b can rotate relative to the other one of the first connection rod 20a and the second connection rod 20b along central axis. By means of the clamp, a light source or a detector can be accurately fixed at a needed angle for various photoelectric property tests, and the angle can be fixed.
Description
Technical field [0001] The invention relates to the technical field of light source performance testing, in particular to a fixture and fixture assembly used for testing the performance of an LED array light source. Background technique [0002] With the rapid development of modern solid-state lighting technology, LEDs are increasingly used in display, signal transmission and lighting fields. Visible light communication technology based on semiconductor lighting is brought about by its high bandwidth, no electromagnetic pollution, good safety, low power consumption, no new special network and frequency licenses, certain mobility, and combination with semiconductor lighting. The advantages of energy saving and environmental protection will become one of the access methods of network user terminals, and with the further development of semiconductor lighting technology and the increasing popularity of semiconductor lighting, it may become the main access method of network terminals....
