Operating Lamp Asymmetric Light Module Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating lamps with multiple light modules struggle to generate a homogeneous total light field due to symmetrical arrangements that restrict heat dissipation and flexibility in light distribution.
Innovation Solution
The operating lamp arranges light modules on a non-regular circular pattern around a central axis, allowing each module to rotate and emit light bundles with principal axes intersecting the projection plane at specific angles, creating a more homogeneous light distribution without forming a regular polygon, and optionally includes different LED color temperatures and optical elements for enhanced light control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If light modules are arranged symmetrically on the lamp surface, then the structural stability and ease of manufacture are improved, but the heat dissipation capability and flexibility in light distribution deteriorate
Solution Approach 1:
The patent applies asymmetry by arranging light modules in an irregular pattern on the lamp surface rather than in a symmetric configuration. Specifically, the light modules are positioned at different radial distances from the central axis and at different angular positions, creating an asymmetric layout that improves heat dissipation pathways and enhances flexibility in light distribution while maintaining structural stability through careful design of the mounting positions.
2Manufacturing precision
If light modules are arranged in a regular polygon pattern, then the manufacturing precision is improved, but the flexibility in light distribution and heat dissipation deteriorate
Solution Approach 1:
The patent applies local quality by giving each light module a unique position and orientation tailored to its specific function and the local requirements of the light field. Each light module can be individually adjusted in terms of its angular position, radial distance, and tilt angle, allowing for optimized light distribution in different regions of the projection plane while maintaining high manufacturing precision through defined mounting positions.
3Device complexity
If light modules are fixed in position, then the device complexity is reduced, but the flexibility in adjusting light intensity and distribution deteriorates
Solution Approach 1:
The patent applies dynamics by making the light modules adjustable in their positions and orientations. Each light module can be independently positioned at different angular locations and radial distances from the central axis, and can be tilted at different angles. This dynamic configurability allows for flexible adjustment of light distribution patterns and intensity in different regions of the projection plane while maintaining relatively simple adjustment mechanisms.

Function Achieved in This Case
This configuration achieves a highly homogeneous total light field with improved heat dissipation and flexibility in light distribution, allowing for adjustments in light intensity and color temperature, while accommodating additional components like cameras without compromising symmetry.
Implementation Method 1
A light module usually has here at least one light-emitting diode (LED) for generating light
Implementation Method 2
At least one light module has a rotation in relation to the lamp surface about such a rotation axis which extends through the light module and which intersects, furthermore, the central axis, so that the principal axis of the light bundle corresponding to the rotated light module does not intersect the central axis

AI summary
An operating lamp has a lamp body with a lamp surface directed towards a light projection surface. The lamp body has a central axis and the light projection plane extends at a preferred working distance from the lamp surface and at right angles to the central axis. The operating lamp has N light modules arranged on the lamp surface on a first circle with a centroid that coincides with the central axis. The light modules are aligned to each emit a light bundle with a respective principal axis towards the light projection plane—the principal axes forming, with the light projection plane N intersections, an ellipse with a centroid coinciding with the central axis. One of the light modules rotates about a rotation axis that passes through the light module, intersects the central axis has a light bundle principal axis that does not intersect the central axis.
