Solution Overview
Problem
Existing lamp control systems for LED lamp strings lack versatility in input modes, particularly in maintaining communication with mobile devices, leading to limitations in remote operation and flash mode control, especially when communication is interrupted.
Innovation Solution
A lamp control apparatus with multiple input modes, featuring a housing, circuit board, flash mode switching module, and sound-controlled flash mode input circuit, where the pickup device is integrated within the housing to prevent damage and ensure stability, allowing for remote operation through various input methods such as buttons, infrared, Bluetooth, or sound waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pickup device is led out of the housing through a lead wire, then the sound-controlled function can be implemented, but the connection may be damaged due to pulling the lead wire
Solution Approach 1:
The pickup device is extracted from the housing structure and integrated directly into the circuit board, eliminating the need for lead wires that connect external components. This extraction resolves the contradiction by maintaining sound-controlled functionality while removing the vulnerable lead wire connection.
Solution Approach 2:
The pickup device is merged with the circuit board to form an integrated assembly. This combining eliminates the separate lead wire connection, thereby maintaining the sound-controlled flash mode input functionality while improving connection reliability by removing the vulnerable external wiring.
2Adaptability or versatility
If multiple input modes are provided, then the operation versatility is improved, but the device complexity increases
Solution Approach 1:
The control circuit is designed with multi-functionality to handle multiple input modes (button input, infrared remote control, Bluetooth wireless communication, and sound-controlled input) through a unified architecture. This universal design resolves the contradiction by providing versatile operation across different input methods while avoiding the need for separate dedicated circuits for each mode, thereby limiting the increase in device complexity.

AI summary
The application discloses a lamp-control apparatus with multiple input modes including a housing, a circuit board arranged in the housing, a flash mode switching module, a sound-controlled flash mode input circuit for receiving external environment sound waves and sending a control command to a control circuit. The control circuit for controlling a light emitting mode of a lamp is arranged on the circuit board. The flash mode switching module and the sound-controlled flash mode input circuit are respectively and electrically connected to the control circuit. The sound-controlled flash mode input circuit includes a pickup device that is located inside the housing. One or more through holes for transmitting the sound waves to the pickup device are formed in the position where the pickup device is mounted on the housing. which has the advantages that the pickup device does not need to be led out of the housing through a lead wire, so that the connection between the pickup device and the circuit board is prevented from being damaged due to pulling the lead wire.
