Abstract

The invention discloses a system and method for quickly testing hydrolysis resistance of an LED chip, and the system comprises a temperature and humidity regulator which is provided with a cavity; a rotating device which is connected to the inner wall of the cavity and can rotate along the inner wall of the cavity; a support of a cup-shaped structure, and a test substrate. The LED chip is installed on the support and is in conductive connection with the support; the support is fixed on the test substrate and electrically connected with the test substrate, and the test substrate is connected tothe rotating device; the direction of the LED chip is adjusted through the rotating device, reverse voltage is introduced into the test substrate, and the temperature and humidity in the cavity are adjusted, so that an impact test is carried out on the LED chip. The direction of the LED chip is adjusted through the rotating device, the hydrolysis speed of the LED chip is effectively increased, and therefore the detection time is shortened.

Description

technical field [0001] The invention relates to a method for testing the hydrolysis resistance of LED chips, in particular to a system and method for rapidly testing the hydrolysis resistance of LED chips. Background technique [0002] Light-emitting diode, the abbreviation of the English word LED, the main meaning: LED=Light Emitting Diode, is a solid-state semiconductor device that can convert electrical energy into visible light. As a lighting device, compared with traditional lighting devices, light-emitting diodes have considerable advantages—— Long life, high light efficiency, no radiation, low power consumption, green and environmental protection. At present, LEDs are mainly used in fields such as display screens, indicator lights, and backlight sources. [0003] Since LED applications will be in a humid environment or exposed to rain outdoors, products with poor hydrolysis resistance will easily fail, so it is necessary to verify the hydrolysis resistance of the pro...
