Problems solved by technology

[0003] However, due to the limited control capability of the power chip, the brightness level of the smart rearview mirror LED light can only be changed within the range of 3-4 levels. Therefore, when using the smart rearview mirror LED light, there may be bright When it's not bright enough, when it's dark it's not dark enough
[0004] In the process of realizing the present invention, the inventor found that the prior art has the following defects: due to the limited brightness level changes of the LED lights of the smart rearview mirror, it is impossible to achieve multi-level changes in the brightness of the LED lights of the smart rearview mirror, and the user experience is poor.

Abstract

The embodiment of the invention discloses a multi-stage control method and device for brightness of an LED lamp, a rearview mirror and a storage medium. The method comprises the steps of acquiring brightness adjustment class of the LED lamp in an intelligent rearview mirror; adjusting a signal parameter of a voltage output signal according to the brightness adjustment class; and providing the adjusted voltage output signal used as a power supply for the LED lamp in the intelligent rearview mirror so as to adjust brightness of the LED lamp in the intelligent rearview mirror. According to the method disclosed by the embodiment of the invention, the brightness of the LED lamp in the intelligent rearview mirror is adjusted by acquiring the brightness adjustment class of the LED lamp in the intelligent rearview mirror, so that multi-stage change of the brightness of the LED lamp in the intelligent rearview mirror is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of brightness control of LED lamps in intelligent rearview mirrors, and in particular to a method, device, rearview mirror and storage medium for multi-level control of brightness of LED lamps. Background technique [0002] Smart rearview mirror LED (Light Emitting Diode, Light Emitting Diode) lights, generally the power supply chip directly supplies power to the LED control circuit. Correspondingly, by changing the way the power chip flows into the LED control circuit Adjustment of the brightness of the mirror LED light. [0003] However, due to the limited control capability of the power chip, the brightness level of the smart rearview mirror LED light can only be changed within the range of 3-4 levels. Therefore, when using the smart rearview mirror LED light, there may be bright Sometimes it's not bright enough, and when it's dark it's not dark enough. [0004] In the process ...
