Abstract

The invention relates to an LED (Light Emitting Diode) module contact force testing device and method. The testing device comprises a base, a force sensor, a supporting frame, a module installation seat, a force transmission shaft, a contact plate and an adapting seat, wherein the force sensor and the lower end of the supporting frame are respectively fixed with the base, and the supporting frame is arranged on the outer side of the force sensor in an enclosed manner; the two ends of the force transmission shaft which is vertically arranged are respectively connected with the force sensor and the contact plate; the module installation seat is arranged on the outer side of the supporting frame, the adapting seat is arranged on the module installation seat, and the upper surface of the adapting seat and the upper surface of the contact plate are at the same level; an LED module to be tested is arranged in the adapting seat, the lower surface of the LED module to be tested is in contact with the upper surface of the contact plate, the contact force of the LED module to be tested is measured through the contact plate, and the contact force is transmitted to the force sensor through the force transmission shaft. The indicating value relative error and the repeatability of the testing device are superior to 0.3 percent, the testing device is applicable to testing of modules with different specifications, the testing device is light, ingenious and convenient to carry, and the testing device can be widely used for testing the contact force of various LED modules.

Description

technical field [0001] The invention relates to a detection device of an LED module, in particular to an LED module contact force test device and a detection method thereof. Background technique [0002] The LED module includes a module holder and an LED lamp. The module holder is generally a plastic part, so the module holder will undergo a large elastic deformation after being squeezed by the LED lamp, while other parts are metal parts with certain rigidity. , the amount of deformation can be ignored, and the force generated by the elastic deformation of the module holder is the contact force of the LED module; because there is a requirement for the measurement of the contact force of the LED lamp in the relevant standards, because if the force is too small, the LED lamp will If the installation is not firm, if the force is too large, it will cause excessive heat generation on the contact surface, which is a hidden danger. Therefore, it is necessary to test the contact for...
