Electronic system, service life management circuit and service life management method

Abstract

The invention provides a service life management circuit used for controlling the utilization ratio of a plurality of electronic elements. The service life management circuit comprises a storage unit for storing use information of each electronic element, a receiving unit for receiving a starting instruction, a computing unit and a control unit coupled with the storage unit, the receiving unit, the computing unit and the electronic elements. When the receiving unit receives the starting instruction, the control unit starts at least one electronic element with low utilization ratio in the electronic elements according to the use information of each electronic element, stored in the storage unit, and controls the computing unit to compute the use time of the started electronic element so as to generate the use information and store the use information in the storage unit. Therefore the utilization ratio of the plurality of electronic elements can be controlled averagely so as to prolong the overall service life of the electronic elements.

Description

technical field [0001] The invention relates to a life management circuit, in particular to a life management circuit which can averagely control the utilization rate of multiple electronic components. Background technique [0002] With the advancement of technology, light-emitting diodes (LEDs) are more and more widely used in various electronic devices, such as indicator lights with indicating functions, various lighting devices, and backlights of display devices. [0003] Taking lighting equipment as an example, most of today's lighting equipment use a light-emitting diode module composed of multiple light-emitting diodes to provide light sources, and provide various mode switching (or multi-stage switching) functions, so that the light-emitting diode module is in each The brightness of the mode and the number of lighted LEDs will be different to meet the various needs of users, for example: the night light mode for reading at night, or the full brightness mode for normal...

AI Technical Summary

Problems solved by technology

However, no matter in which mode, there are always some LEDs in the LED module that will be lit in different modes, so that the service life of these LEDs will be reduced due to long-term use, otherwise those LEDs that are only in a specific mode The lifespan of the light-emitting diodes that are only lighted in the middle is relatively long. However, as long as some light-emitting diodes are damaged, the lighting function will be affected, and the entire light-emitting diode module must be replaced, so that the light-emitting diode module will be damaged due to uneven utilization of the light-emitting diodes. Must be replaced early and lead to an increase in the cost of repairing the lighting equipment for the user
