Abstract

The invention discloses a design system and method for the controllable life of LED lamps. The system includes: basic data management, failure mechanism management and simulation modeling functions; the steps involved in designing the controllable life of LED lamps: setting LED lamps All the failure points in the system; set the parameters related to the failure point; select the appropriate failure model to analyze the failure point; give the results of the life calculation of each model for each model, and combine each model to obtain the designed LED lamp life; Analyze multiple failure points in sequence. The invention comprehensively considers the structure and environmental conditions of the LED lamp, and combines common failure models to realize accurate evaluation of the life of the LED lamp.

Description

technical field [0001] The invention relates to the technical field of LED product testing, in particular to a design system and method for controlling the service life of LED lamps. Background technique [0002] At this stage, when designing LED lamps, technicians cannot effectively design reliability and estimate product life in combination with the structure of LED lamps and the environmental conditions in which LED lamps are used in the design stage, and it is difficult to realize the controllable life design of LED lamps. [0003] In the existing technology, enterprises generally adopt the trial and error method to design LEDs. By repeatedly modifying LED design parameters and producing LED lamp samples for life experiment verification, the design scheme for the target life is finally obtained. Because the design is repeated and iterative, and the life test of LED lamps takes a long time, the design cycle of traditional LED lamps is long and the cost is high. During the...
