Problems solved by technology

The COB LED test device has a special analyzer and manual visual inspection. There are many special instruments, high cost, strong professionalism, and high requirements for users. It is mainly for the R&D departments of large enterprises; some small enterprises with limited technical strength and capital Using the method of manual visual inspection has obvious disadvantages. It requires the experience of the testers, the workload is heavy, and it is easy to visual fatigue, which leads to missed detection and misjudgment, and finally leads to low efficiency.

Abstract

The invention provides a photoelectric testing device of a COB LED device. The photoelectric testing device comprises the COB LED device, an integrating sphere, a photoelectric sensor, an illuminometer, a COB LED tester and a display. When the integrating sphere carries out photoelectric testing on the COB LED device, photoelectricity of different colors of the COB LED device is tested, one-time testing is carried out on the color and the brightness of the COB LED, a relative value is read to serve as a standard value, the upper limit and the lower limit of the standard value are set, then the relative values of the to-be-tested COB LEDs are read in batches and compared with the standard value, and therefore good products and defective products are judged. The testing precision is effectively guaranteed, on-line testing and function testing of the COB LED tester are combined, testing stations do not need to be added, efficiency is improved, rapidness and full automation are achieved, and man-made missed judgment is avoided.

Description

technical field [0001] The invention relates to the technical field of photoelectric testing, in particular to a photoelectric testing device of a COB LED device. Background technique [0002] As a kind of electro-optic conversion device, COB LED not only requires high external quantum efficiency, but also has excellent photoelectric properties as one of the key factors determining its electro-optic conversion efficiency. Therefore, the in-depth study of I-V characteristics is helpful to design and prepare high-performance LED devices. The COB LED test device has a special analyzer and manual visual inspection. There are many special instruments, high cost, strong professionalism, and high requirements for users. It is mainly for the R&D departments of large enterprises; some small enterprises with limited technical strength and capital The disadvantages of manual visual inspection are obvious. It requires testers' experience, heavy workload, and easy visual fatigue, which ...
