Solution Overview
Problem
Existing light fixtures struggle to create a high number of varied light effects due to limited space and focusing capabilities, making it difficult to achieve both compactness and versatility in lighting systems, especially in projecting light devices where beam shaping objects need to be precisely positioned.
Innovation Solution
A multisource illumination device with multiple light sources grouped by radial distance from the primary optical axis, where each group's dimming level is independently controlled based on its radial distance, allowing for variable focus depth and light output, enabling a wide range of new light effects and increased electro-optical efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple beam shaping objects are positioned in the focal point to create various light effects, then the number of light effects increases, but the device size and complexity increase
Solution Approach 1:
The patent divides the illumination device into multiple groups of light sources, with each group positioned at a different radial distance from the optical axis. Each group can be independently controlled to create different light effects, replacing the need for multiple physical beam shaping objects in the focal point.
Solution Approach 2:
Instead of placing multiple beam shaping objects in the same focal point (one-dimensional positioning), the patent distributes light sources across different radial distances from the optical axis (two-dimensional positioning). This spatial distribution in the illumination domain achieves multiple light effects without increasing the size of the focal area.
2Adaptability or versatility
If multiple beam shaping objects are positioned in the focal point to create various light effects, then the number of light effects increases, but the positioning precision requirements increase
Solution Approach 1:
The patent segments the light source array into multiple groups based on radial distance from the optical axis. Each group can be independently controlled, eliminating the need for precise positioning of multiple beam shaping objects in the focal point. The segmentation approach tolerates larger manufacturing variations while maintaining control over light effects.
Solution Approach 2:
Instead of using multiple physical beam shaping objects that require precise positioning, the patent uses multiple groups of light sources that replicate the functionality of beam shaping objects through independent control. This virtual replication through light source groups reduces the need for precise mechanical positioning.
3Ease of operation
If the illumination device is made compact for easier handling, then the device size decreases, but the number of achievable light effects decreases
Solution Approach 1:
The patent achieves multiple light effects in a compact device by utilizing the radial dimension from the optical axis to distribute light source groups. This two-dimensional arrangement (radial distance and angular position) allows multiple independent light effects to be generated within a small footprint, maintaining ease of handling while increasing versatility.
Solution Approach 2:
Each group of light sources positioned at different radial distances can serve multiple functions by being independently controlled. The same compact illumination device can generate various light effects by activating different groups or combinations of groups, achieving multi-functionality without increasing device size.

AI summary
A method for controlling a multisource illumination device in gated optical system is provided, wherein a plurality of light sources are divided into groups, and wherein each group is characterized by a respective radial distance from a primary optical axis. Therein, the dimming level of a group is controlled independently from the dimming level of other groups based on the radial distance of the group from the primary optical axis.
