Lighting Device With Independent Projection And Illumination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices with video-image projection functions lack effective control over light emission and video-image projection settings, making them inconvenient for users and lacking a detailed optical system layout, which hinders user-friendly operation and setting techniques.
Innovation Solution
A lighting device incorporating a projection-type video-image display unit with content editing capabilities and a lighting unit for illumination, featuring a specific optical unit layout and control systems that allow for independent control of illumination light and video-image projection, along with interactive functions using sensors and input units for user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a projector and illumination light source are integrated into a lighting device, then the device can provide both video-image projection and illumination functions, but there is no disclosure on control of light emission and video-image projection settings, making it inconvenient for users
Solution Approach 1:
The patent divides the lighting device into distinct functional modules: a lighting unit for illumination and a projection-type video-image display unit for video projection. Each unit can be controlled independently through separate control circuits, allowing users to adjust illumination and projection settings separately, thereby improving ease of operation while maintaining dual functionality.
Solution Approach 2:
The patent implements dynamic control capabilities where the illumination light source and projection light source can be independently adjusted in terms of intensity, timing, and operational mode. The control system allows for flexible switching between different operational states (e.g., illumination only, projection only, or both simultaneously), enhancing user convenience.
2Adaptability or versatility
If a projector is added to a lighting device, then video-image projection function is achieved, but there is no detailed optical system layout disclosed, hindering effective control and setting
Solution Approach 1:
The patent integrates the projection optical system within the housing of the lighting device, nesting the projector components (light source, optical elements, projection lens) inside the overall device structure. This nested arrangement consolidates the optical system layout, making it more manageable and easier to control while maintaining the video-image projection function.
3Ease of operation
If conventional lighting control is used, then simple operation is maintained, but lighting control more convenient for users and setting processing of projection video image has not been sufficiently considered
Solution Approach 1:
The patent implements a control system that serves multiple functions: it controls both the illumination light source and the projection light source, manages different operational modes, and handles setting adjustments for both units. This multi-functional control approach enhances user convenience without proportionally increasing device complexity, as the same control infrastructure serves multiple purposes.
