Adaptive Luminaire with Segmented Light Engines
Solution Overview
Problem
Conventional luminaires are limited to a single pre-specified light distribution pattern, which cannot be dynamically changed, requiring multiple luminaires for varying illumination needs and lacking adaptability to environmental conditions.
Innovation Solution
A luminaire with multiple interchangeable light engines, each capable of different light distributions, which can be independently controlled to adjust light output based on environmental parameters and sensor inputs, allowing for dynamic changes in light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single set of optics is used in a luminaire, then the structure is simple and manufacturing is easy, but the light distribution cannot be dynamically changed
Solution Approach 1:
The luminaire is divided into multiple independent light engines, each with its own optics. Each light engine can be independently controlled to produce different light distributions. This segmentation allows the system to achieve multiple light distribution patterns while keeping each individual component relatively simple.
Solution Approach 2:
Multiple light engines with different optical properties are integrated into a single luminaire housing. By selectively activating different combinations of light engines, the luminaire can provide multiple light distribution patterns (Type I, Type II, Type III, Type IV, or Type V) for different application scenarios, making the luminaire universally adaptable.
2Adaptability or versatility
If multiple luminaires are provided to achieve multiple distribution patterns, then the required light distributions are met, but the quantity of devices and installation complexity increase
Solution Approach 1:
Multiple light engines that would traditionally require separate luminaires are merged into a single luminaire housing. Each light engine maintains its independent optical characteristics, but they are physically integrated and controlled together, reducing the total number of luminaire units needed while maintaining the ability to provide multiple light distribution patterns.
Solution Approach 2:
A single luminaire is designed to perform multiple functions by incorporating different types of light engines. The luminaire can be configured to provide various light distribution patterns (Type I through Type V) depending on the application requirements, eliminating the need for multiple specialized luminaires.
3Illumination intensity
If dimming is applied to change luminance, then the brightness is adjusted, but the distribution pattern remains unchanged
Solution Approach 1:
The luminaire system dynamically changes its light distribution pattern by selectively activating different light engines based on environmental conditions or user requirements. Unlike simple dimming that only changes intensity, this dynamic reconfiguration allows the distribution pattern itself to change, providing adaptability to different scenarios such as rainy conditions, nighttime security, or daytime illumination.

AI summary
A luminaire may include a plurality of different light engines. Light engines having different light distributions can be included in a single luminaire and a subset of the light engines selectively driven to dynamically change the light distribution of the luminaire. In this way, a single luminaire is capable of illuminating an area with a variety of different light distributions.
