Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination apparatuses using LEDs lack the capability for special illumination modes, such as high illuminance or emergency lighting, beyond their normal operation.
Innovation Solution
An illumination apparatus comprising a main illumination light source with a predetermined luminescent color, a sub illumination light source adjustable to arbitrary colors, and a control unit that mixes and controls the lighting of both sources to achieve various modes, including high illuminance, backup, and dramatization modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only main illumination light source is used during normal use, then device complexity is reduced, but special illumination capability (high illuminance mode) cannot be achieved
Solution Approach 1:
The sub illumination light source is designed to serve multiple functions: it can operate independently for special illumination modes (high illuminance, emergency, dramatization) and work in conjunction with the main illumination light source for enhanced lighting effects. This multi-functional design enables a single component to provide both normal and special illumination capabilities without requiring separate dedicated systems.
Solution Approach 2:
The illumination system is divided into two independent light sources: the main illumination light source for normal use and the sub illumination light source for special purposes. This segmentation allows each source to be optimized for its specific function while enabling versatile illumination modes through their coordinated operation, resolving the contradiction between simplicity and versatility.
2Adaptability or versatility
If sub illumination light source is added for special illumination modes, then adaptability improves, but device complexity increases
Solution Approach 1:
The control unit is designed with universal control capabilities that manage both the main illumination light source and the sub illumination light source through a single integrated system. This universal controller can execute multiple illumination modes (normal, high illuminance, emergency, dramatization) by coordinating the two light sources, thereby improving adaptability without proportionally increasing control complexity.
3Illumination intensity
If main illumination light source operates at high power for emergency lighting, then illuminance increases, but energy consumption increases
Solution Approach 1:
For high illuminance modes such as emergency lighting or dramatization effects, the system merges the output of both the main illumination light source and the sub illumination light source. This combining approach allows the system to achieve high illuminance levels by utilizing both light sources simultaneously, rather than over-driving a single source, thereby managing energy consumption more efficiently while achieving the desired lighting intensity.
