LED Dimmer Switch With Independent Charging Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative lighting dimmer switches for LED lamps either disable charging when dimming is activated or require the light source to be on for charging, which is not energy-efficient and inconvenient for consumers.
Innovation Solution
A decorative lighting dimmer switch that incorporates a constant current source driving module, including a PT4115 driving chip, a voltage stabilizing module, and an adjustment oscillating module, allowing for simultaneous charging and dimming by connecting these components in series between the charging module and the LED lamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dimmer switch is mounted on the lamp body to enable dimming function, then the lighting function can be dimmed, but the charging function cannot be achieved when the light source is turned off
Solution Approach 1:
The patent divides the control circuit into separate functional modules: a dimming control module that operates independently from the charging module. The dimming control module includes a dimmer switch and control circuit that can regulate LED brightness without affecting the charging interface, allowing both functions to operate simultaneously or independently based on user needs.
Solution Approach 2:
The patent creates a multi-functional lamp system where the same LED lamp can serve both as a lighting source and a charging device. The control circuit is designed to accommodate both dimming operation and charging operation, enabling the lamp to perform multiple functions without requiring separate systems or sacrificing either function.
2Adaptability or versatility
If the light source is turned on to enable charging function, then charging can be achieved, but energy is wasted and environmental protection is compromised
Solution Approach 1:
The patent separates the charging function from the lighting function by providing an independent charging module that can operate without requiring the LED light source to be on. The charging module includes a charging interface and control circuit that can independently manage charging operations, eliminating the need to waste energy by keeping the light on for charging purposes.
3Ease of operation
If the dimming function is selected, then the lighting function can be dimmed, but the charging function must be sacrificed
Solution Approach 1:
The patent implements independent control circuits for both dimming and charging functions. The dimming control circuit includes a dimmer switch that can adjust lighting brightness without interfering with the charging module, while the charging module maintains its own independent control for charging operations. This segmentation allows both functions to coexist without requiring users to choose one over the other.

AI summary
A decorative lighting dimmer switch without influencing charging is provided. The decorative lighting dimmer switch includes a charging module used for providing 12V direct current, wherein the charging module is connected to a charging interface of a light emitting diode (LED) lamp. The decorative lighting dimmer switch further includes a constant current source driving module connected to the charging module, wherein the constant current source driving module is connected to the LED lamp, and the constant current source driving module is a constant current source driving circuit including a PT4115 driving chip. The decorative lighting dimmer switch achieves a charging function and an on-line dimming function at a same time by arranging the constant current source driving module to drive the LED lamp to satisfy requirements of consumers.
