AI Technical Summary

Problems solved by technology

The ensuing problems are flickering, uneven utilization of LEDs, and underutilization of LEDs
A further problem is that some of the LEDs have a higher utilization rate than other LEDs, so these LEDs tend to suffer damage such as light decay earlier

Abstract

A light emitting diode circuit, comprising: a first light emitting diode, a second light emitting diode, a third light emitting diode, a fourth light emitting diode and a configuration control module. The configuration control module is electrically coupled to the first light emitting diode, the second light emitting diode, the third light emitting diode and the fourth light emitting diode respectively. The configuration control module is used for adjusting the first light emitting diode, the second light emitting diode, the third light emitting diode and the fourth light emitting diode to selectively switch to a first configuration and a second light emitting diode according to the driving voltage applied to the light emitting diode. configuration, a third configuration or a fourth configuration.

Description

Technical field [0001] The present invention relates to a light-emitting diode circuit, in particular to a light-emitting diode circuit with low flicker and high utilization rate suitable for being directly driven by alternating current. Background technique [0002] As a high-efficiency light-emitting component, light-emitting diodes have been widely used in various lighting fields. Among them, the light-emitting diode circuit that is suitable for directly driven by AC power does not require an AC-DC converter, so the light output efficiency is higher. [0003] However, the common LED circuits directly driven by alternating current on the market often drive different numbers of LEDs with the driving voltage. The ensuing problems are flicker, uneven utilization of light-emitting diodes, and low utilization of light-emitting diodes. A further problem is that some of the light-emitting diodes have a higher utilization rate than other light-emitting diodes, so this part of the light...
