Abstract

The invention discloses a method and a device for acquiring the color change failure source of a light-emitting diode (LED) light source device. The method comprises the steps of acquiring spot elements and color change failure result composition in color change spots in an LED light source color change area on the LED light source device; analyzing the elements in lamp parts on the LED light source device by an X-ray energy spectrometer, and determining the lamp parts which can lead to LED light source color change based on the spot elements; arranging the determined lamp parts which can lead to LED light source color change and silver-containing authentication material in a seal cavity together to carry out a component failure reaction; judging whether the result of the failure reaction corresponding to each part is consistent with the color change failure result of the LED light source color change area or not to determine the lamp part to be the source leading to the LED light source color change failure. After the method and the device are adopted, the source leading to color change failure of an LED light source can be rapidly detected, so that the source possibly causing light source failure can be obtained.

Description

technical field [0001] The invention relates to the technical field of semiconductor light-emitting diodes (LEDs), in particular to a method and a device for obtaining the source of discoloration and failure of LED light source devices. Background technique [0002] LED (Light Emitting Diode) is a solid-state semiconductor device that converts electrical energy into light energy. It has the advantages of low power consumption, good light concentrating effect, fast response, strong controllability, high impact resistance, long service life, and environmental protection. LEDs are gradually replacing traditional light sources and becoming the fourth generation of light sources. [0003] For the LED light source, the packaging support or the substrate has a great influence on the reliability of the light source. Generally, the bracket manufacturer will set the coating on the bracket or the functional area of ​​the substrate. The coating can increase the connection strength be...
