Switching device with auxiliary power unit and wireless receiver function, and lamp system using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless lamp systems and electronic devices become inconvenient to control remotely once the switching device enters a power-off state, as the wireless controller becomes inoperative, requiring users to physically interact with the device to restore control.
Innovation Solution
A switching device with an auxiliary power unit and wireless receiver function, allowing the control unit, wireless module, and input unit to remain operative, enabling wireless control even when the power switching portion is in a power-off mode, using an auxiliary power unit to supply electricity to these components and allowing remote operation through a wireless controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the switching device cuts off external power supply to turn off the lamp, then the lamp is successfully turned off, but the wireless module in the switching device becomes inoperative and wireless control is lost
Solution Approach 1:
The patent divides the power supply system into two independent segments: the main power switching portion that controls the lamp, and the auxiliary power unit that independently powers the control unit and wireless module. This segmentation allows the lamp to be turned off while maintaining power to the control and wireless functions, resolving the contradiction between energy savings and operational availability.
Solution Approach 2:
The auxiliary power unit serves multiple functions: it powers the control unit, enables wireless module operation, and maintains system responsiveness even when the lamp is off. This multi-functionality ensures that the switching device can continue to receive and process wireless control signals without requiring physical interaction, thus maintaining ease of operation while managing power consumption.
2Loss of energy
If the switching device enters power-off state to save energy, then power consumption is reduced, but the user must physically interact with the device to restore control
Solution Approach 1:
By segmenting the power supply into main and auxiliary portions, the patent ensures that control and wireless functions remain powered continuously. This allows users to restore control immediately through wireless commands without needing to physically access the device, eliminating time loss while maintaining energy efficiency through intelligent power management.
Solution Approach 2:
The auxiliary power unit is pre-configured to maintain power to the wireless module and control unit even when the lamp is off. This preliminary preparation ensures that the system is always ready to receive wireless commands, eliminating the delay that would otherwise occur when trying to restore control after power-off state.
3Ease of operation
If the switching device maintains continuous power to wireless module for remote control, then wireless control is always available, but power consumption increases
Solution Approach 1:
The patent segments the power consumption into essential functions (wireless module and control unit) powered continuously by the auxiliary power unit, and non-essential functions (lamp lighting) that can be powered off. This segmentation enables wireless control availability while managing overall power consumption through intelligent separation of critical and non-critical power requirements.

AI summary
Provided are a switching device with an auxiliary power unit and a wireless receiver function, and a lamp system using the same, wherein the switching device is connectable to a lamp and includes a power switching portion, which transmits external electricity to the lamp when in a power supplying mode and stops doing so when in a power-off mode; and the auxiliary power unit in the switching device keeps powering other components of the switching device, so while the power switching portion is in the power-off mode, a wireless module in the switching device can still transmit a wireless signal from a wireless controller to a control unit to adjust the power switching portion to the power supplying mode. Thus, even when the switching device is in a power-off state, a user can control the lamp by sending a wireless control signal to the switching device through the wireless controller.
