Audio Mixing Console LED Brightness Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Audio mixing consoles lack the ability for users to easily adjust the brightness and hue of multicolor LED units, leading to variations in light-emitting properties among LEDs, which complicates operations and increases costs due to the need for automatic measurement and correction mechanisms.
Innovation Solution
An audio mixing console with a memory for storing lighting control data, a lighting control section, and operation mode switching capabilities that allow users to switch between brightness and hue adjustment modes, enabling them to specify colors and adjust the corresponding LEDs' brightness or hue directly through the console's interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If automatic measurement and correction mechanisms are used to adjust LED brightness, then manufacturing precision of LED lighting is improved, but device complexity and cost increase
Solution Approach 1:
The system performs self-adjustment by detecting the pressed operator and automatically setting its LED brightness to match the reference brightness, eliminating the need for external measurement and correction mechanisms while achieving uniform LED lighting across all operators
2Manufacturing precision
If automatic measurement mechanisms are implemented for each LED, then brightness consistency is improved, but ease of operation deteriorates due to complex setup procedures
Solution Approach 1:
The system automatically detects which operator is pressed and performs the brightness matching adjustment itself, requiring no manual measurement or complex setup operations from the user while achieving consistent LED brightness across all operators
3Manufacturing precision
If reference brightness values are stored for each operator, then brightness uniformity is improved, but memory requirements and device complexity increase
Solution Approach 1:
The system copies the reference brightness value from the reference operator to the pressed operator's LED, achieving brightness uniformity through value replication rather than complex storage and retrieval mechanisms for each operator

AI summary
An audio mixing console includes a brightness adjusting mode selection button and an adjustment subject specification button. A user operates the brightness adjusting mode selection button to set up a brightness adjusting mode, and operates the adjustment subject specification button to specify any color LED of RGB or all colors as an adjustment subject. When an LED button is operated, brightness of an LED of a color of an adjustment subject in a multicolor LED unit incorporated in the LED button is increased one step by one step. In another example, in response to an operation of a button, brightness of an LED of a color of the adjustment subject in the multicolor LED unit incorporated in a plurality of LED buttons other than this button is increased one step by one step. This work is carried out for every LED and LED button.
