Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaire designs require complex and costly manufacturing processes due to the need for different housings and focusing optics for various types of LEDs, such as monochrome, tunable white (TW), and RGB luminaires, which complicate the production and assembly.
Innovation Solution
A modular luminaire system comprising a first luminaire with a focusing optic and a second luminaire with a light guide, where both share identical housings and focusing optics, allowing for the use of identical parts and simplified assembly by positioning LEDs and light guides at specific target positions to achieve consistent light distributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different housings and focusing optics are used for various types of LEDs (monochrome, TW, RGB), then the light distribution requirements can be met, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single housing and focusing optic that can accommodate multiple types of LEDs (monochrome, TW, RGB). The focusing optic is designed with a specific target position that works for all LED types, eliminating the need for different housings and optics for each LED type. This reduces manufacturing complexity while maintaining light distribution precision.
Solution Approach 2:
The patent segments the luminaire into modular components where the housing and focusing optic are separate from the LED module. This allows the focusing optic to be designed independently with a universal target position, while the LED module can be configured differently for various applications. The segmentation enables standardized production of the focusing optic while accommodating different LED types.
2Adaptability or versatility
If multiple types of luminaires (monochrome, TW, RGB) are manufactured with different housings, then each can be optimized for its specific LED type, but production costs and assembly time increase
Solution Approach 1:
The patent creates a universal housing and focusing optic design that can be used across all luminaire types (monochrome, TW, RGB). This universal design increases adaptability while improving production efficiency by eliminating the need to manufacture different housing variants. The same focusing optic with its specific target position can accommodate all LED types through appropriate LED module configuration.
Solution Approach 2:
The patent merges the housing and focusing optic into a single standardized assembly that serves all luminaire types. Instead of manufacturing separate housings for each LED type, the design combines these elements into one universal component that can be produced efficiently in large quantities and assembled with different LED modules as needed.
