Abstract

The invention discloses a method and a device for detecting defects of an LED light source chip. An LED light source before encapsulation is subjected to defect detection, so that whether the LED chip cannot be lightened or not, missing of the chip or even electricity leakage can be detected; the overall detection process is automatically controlled, so that the detection efficiency is greatly improved, the detection cost is reduced, and eyes of workers are prevented from being injured by manual detection. A high-precision CCD (charge coupled device) is used for shooting and processing, so that the detection efficiency is greatly improved; information data are subjected to automatic statistics and detection, so that big data comparison, production and management are facilitated.

Description

technical field [0001] The invention relates to an LED light source collar molding chamber, and relates to a method and a device for detecting the defect of an LED light source chip. Background technique [0002] As a new generation of lighting source, compared with traditional light sources such as incandescent lamps, LED light source has the advantages of long life, high luminous efficiency, energy saving and environmental protection, and has become a product with a wide range of uses in recent years. Medical and other fields have put forward strict requirements on the performance of LED light sources under various environmental conditions. [0003] LED light sources are usually composed of multiple chips connected in series. During the production process, it cannot be completely avoided that some of the chips are not bright or missing, which will affect the light efficiency and chip life of the LED light source. The LED light source with multiple chips connected in serie...
