Abstract

The invention discloses a detection method and device for failure probability of an illuminating system. The detection method for failure probability of the illuminating system comprises the following steps of: acquiring the failure probability of multiple subsystems in the illuminating system in the first time quantum; determining the failure probability of the illuminating system in the first time quantum according to the failure probability of the subsystems in the first time quantum; determining the failure probability of the subsystems in the illuminating system in the second time quantum according to the failure probability of the subsystems in the illuminating system in the first time quantum; determining the failure probability of the illuminating system in the second time quantum according to the failure probability of the subsystems in the second time quantum; and determining the failure probability of the illuminating system according to the failure probability of the illuminating system in the first time quantum and the failure probability of the illuminating system in the second time quantum. According to the detection method and device for the failure probability of the illuminating system, the performance of the illuminating system can be more accurately known.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a method and device for detecting failure probability of an illumination system. Background technique [0002] In order to estimate the reliability of lighting equipment, it is necessary to detect the failure probability of the lighting system. In the existing technology, the LED of the lighting system is generally detected. If the LED fails, the lighting system will fail, and the lighting is judged only by the failure probability of the LED. The probability of failure of the system is not accurate. [0003] For the problem that the failure probability of the lighting system cannot be accurately detected in the prior art, no effective solution has been proposed so far. Contents of the invention [0004] The invention provides a method and device for detecting the failure probability of the lighting system to at least solve the problem that the failure probability of the lighting...
