Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing examination lights with multiple light-emitting diodes distributed across the lighting surface face challenges in maintenance, as replacing a single defective diode can lead to color irregularities due to aging or mismatched wavelengths, and require complex recalibration, making them less user-friendly and prone to shadowing.
Innovation Solution
A modular lighting system featuring semiconductor light sources, including LEDs, with a common optic that mixes and collimates light to maintain color consistency and brightness, allowing for easy replacement and upgrade, and incorporating a heat sink for effective cooling, enabling efficient heat dissipation and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple LEDs are distributed across the lighting surface, then illumination coverage is improved, but maintenance complexity increases due to recalibration requirements and color irregularities
Solution Approach 1:
The lighting system is divided into multiple interchangeable modules, each containing one or more LEDs with dedicated optics. This segmentation allows individual modules to be replaced without affecting other modules, eliminating recalibration needs while maintaining comprehensive area coverage through the distributed module arrangement.
Solution Approach 2:
The patent implements a replaceable module concept where defective LED modules can be easily discarded and replaced with new or refurbished modules. This approach recovers the functional lighting capability without requiring complex maintenance procedures, calibration, or matching of individual LED characteristics.
2Manufacturing precision
If individual LEDs have dedicated optics, then light focusing precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the LED light source and its dedicated optics into a single integrated module. This merging maintains the precise light focusing capability of dedicated optics while reducing overall system complexity by pre-assembling and standardizing the optical components within each replaceable module, eliminating the need for complex field adjustments.
3Productivity
If a single defective LED is replaced, then continuity of operation is improved, but color consistency deteriorates due to aging and wavelength mismatch
Solution Approach 1:
By segmenting the lighting system into modular units, the patent enables replacement at the module level rather than individual LED level. This ensures that replaced modules are new or refurbished units with consistent optical characteristics, maintaining color consistency across the entire lighting surface while ensuring operational continuity.
Solution Approach 2:
The replaceable module design allows defective modules to be discarded and replaced with refurbished or new modules that have known, consistent optical properties. This approach recovers the lighting function while guaranteeing color consistency, as each module is a standardized unit with controlled LED characteristics.
