Lighting Control Console Slide Knob Light Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting control consoles face safety issues due to external electrical components and heating problems caused by illuminants in the control knobs, which are undesirable in dark environments like theaters or concert halls.
Innovation Solution
The lighting control console features a slide control with a light source located inside the housing, using a light conducting element to transmit light to the control knob, ensuring electrical safety and preventing overheating by keeping electrical components within the housing and using LEDs for efficient lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an illuminant (light bulb) is installed in the control knob to provide lighting in dark environments, then the control knob can be seen and accessed safely, but electrical safety is compromised and the control knob may heat up
Solution Approach 1:
The light source is extracted from the control knob and relocated to the interior of the housing. This separation removes the electrical component from the user-accessible area, eliminating the electrical shock hazard while maintaining the lighting function through the light conducting element that transmits light from the interior source to the exterior control knob area.
Solution Approach 2:
A light conducting element (such as an optical fiber or light guide) is introduced as an intermediary between the light source in the housing interior and the control knob exterior. This intermediary transmits the illuminating light without conducting electricity, thereby providing lighting while maintaining electrical isolation and safety.
2Illumination intensity
If an illuminant is installed in the control knob, then the control knob can be illuminated in dark environments, but the control knob may heat up which is undesired
Solution Approach 1:
The light source is extracted from the control knob and placed inside the housing. This removes the heat-generating electrical component from direct contact with the control knob, preventing overheating while still providing illumination through the light conducting element that transmits light without conducting heat significantly.
3Use of energy by moving object
If cabling is laid from the interior of the housing to the control knob outside the housing to supply electricity to the illuminant, then the illuminant can be powered, but considerable safety problems result
Solution Approach 1:
The electrical power supply connection is extracted from the control knob area and relocated to the interior of the housing. The light conducting element serves as a non-conductive intermediary that transmits light without requiring electrical cabling to extend outside the housing, thereby eliminating the electrical safety hazard.
Solution Approach 2:
The light conducting element acts as a non-electrical intermediary that transmits optical energy from the light source in the housing interior to the control knob exterior without requiring electrical conductors to bridge the boundary, thus avoiding electrical safety issues.
