The invention relates to the technical field of LED detection equipment, and discloses a device and method for inspecting the characteristics of an LED light source. The device comprises a constant current drive unit, a light splitting path unit, a processing unit, and a CCD sensor, an RGB color sensor, a voltage detection unit and a display unit electrically connected to the processing unit; theconstant current drive unit is connected the inspected LED light source; the light splitting path unit is used to split the light emitted by the LED light source and project the split light to the CCDsensor; the RGB color sensor is used to acquire brightness signals of red, green, and blue color components of the LED light source; an input end of the voltage detection unit is connected to the LEDlight source, and is used to collect forward voltage of the LED light source. The processing unit coordinates the CCD sensor, the RGB color sensor and the voltage detection unit and processes the inspection signals, thereby avoiding misoperation caused by manual inspection, reducing the connection time between various characteristic inspection processes, and improving the production efficiency.
Description
technical field [0001] The invention relates to the technical field of LED testing equipment, in particular to a device and method for testing the characteristics of an LED light source. Background technique [0002] In the LED production process, it is necessary to inspect the characteristics of the LED light source. The characteristics of the LED light source include many characteristics such as LED forward voltage, brightness, and wavelength. In the inspection process, a variety of inspection equipment is required. The testing process is cumbersome and manual operation. It is easy to make mistakes, it is difficult to ensure the consistency of inspection process control, and the work efficiency is low. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to solve at least one of the technical problems existing in the prior art, and provide a LED light source characteristic inspection device, which is used ...
