An online detection device for accelerated life of LED lamps

Abstract

An accelerated life online testing device for LED lighting lamps belongs to the field of reliability testing of semiconductor devices. In order to solve the problems in the prior art, a test box includes an optical measurement channel and a temperature application unit, and the optical measurement channel is located in the test box. The connection point with the external integrating sphere system; the lamp fixture device, which is set in the test box, which is a positive and negative 360° rotatable multi-position independent lamp stand, and the tested LED lamp sample is installed on the lamp fixture device; the external integrating sphere The system, which is closely connected with the test box without light leakage, and the temperature-insulating and evacuated double-layer glass tube is placed inside the external integrating sphere system; the control host, which is respectively connected with the test box, the external integrating sphere system and the computer through data lines , used to control the acceleration temperature setting of the test box and the test parameter setting of the external integrating sphere; the computer is used to display the online data of the control host in real time; the device can quickly display the performance of LED lighting products.

Description

technical field [0001] The invention belongs to the field of reliability detection of semiconductor devices, and in particular relates to a life-span acceleration test device for LED lighting lamps. Background technique [0002] With the improvement of LED light source light efficiency, color rendering, luminous output of a single module and the reduction of price, LED technology is gradually entering the field of general lighting applications. However, if LED lighting fixtures are to completely replace incandescent lamps and fully enter the general lighting market, people still lack sufficient confidence. The reason is that people still have certain doubts about the quality of LED lighting fixtures. As we all know, LED lighting products are long-life semiconductor devices. The traditional non-accelerated aging test (US Energy Star recommends 6000 hours) is no longer suitable for testing current LED lighting fixtures. How to quickly and scientifically evaluate the The lifes...
