Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing directional lamps and lighting devices lack flexibility in adjusting beam angles and profiles after installation, requiring users to select the desired beam characteristics before purchase and not allowing for post-installation adjustments.
Innovation Solution
A retrofit lighting device with a configurable beam angle and profile, featuring a secondary optic disc with multiple types of secondary optical elements that can be rotated to align with LED packages, allowing users to select from predefined operating modes that define specific beam angles and profiles using a selector or remote switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lighting device provides a specific beam angle, then the light output is consistent and reliable, but the user cannot adjust the beam angle after installation
Solution Approach 1:
The patent implements a rotatable secondary optic disc that allows the beam angle to be dynamically adjusted after installation. The disc can be rotated to different positions to select between multiple pre-configured beam angles (e.g., 24°, 36°, 48°), transforming a static lighting device into a dynamic one that adapts to different lighting requirements without requiring multiple separate devices.
Solution Approach 2:
The lighting device is designed with multiple beam angles built into a single unit through the rotatable optic disc, making it universally applicable to various lighting scenarios (e.g., accent lighting, flood lighting, task lighting). This multi-functionality eliminates the need for users to purchase multiple separate lighting devices for different beam angle requirements.
2Ease of operation
If the lighting device allows beam angle adjustment, then user flexibility is improved, but the device structure becomes more complex
Solution Approach 1:
The optical system is segmented into multiple discrete secondary optical elements (lens, reflector, or combination) mounted on the rotatable disc. Each segment corresponds to a specific beam angle configuration. This segmentation allows the complex adjustment function to be broken down into simple, discrete positions that are easy to select and operate.
Solution Approach 2:
The beam angle configurations are pre-set during manufacturing by positioning the secondary optical elements at specific locations on the rotatable disc. Users do not need to perform complex adjustments or calculations; they simply rotate the disc to the desired pre-configured position, making the operation intuitive and easy to use.
3Adaptability or versatility
If multiple secondary optical elements are used, then beam angle and profile customization is enabled, but the device complexity increases
Solution Approach 1:
The patent combines multiple secondary optical elements (lens and reflector, or different lens configurations) onto a single rotatable disc. By merging these elements into one integrated component that can be rotated to different positions, the device achieves beam profile configurability without requiring multiple separate optical assemblies, thereby limiting the increase in overall device complexity.
