Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to effectively integrate environmental sensors into LED-based lighting fixtures to leverage their added intelligence for lighting control based on environmental conditions such as ambient light and occupancy, while ensuring efficient installation and removal of these sensors within the fixtures.
Innovation Solution
A sensor module is integrated into the lighting fixture, which includes one or more environmental sensors and can be easily installed or removed, with the sensor module being coupled to the heatsink of the lighting fixture. This module houses sensors like occupancy and ambient light sensors, and its readings can be used to control the light output of the fixture and shared with other fixtures in the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If environmental sensors are integrated into LED lighting fixtures to enable intelligent lighting control, then lighting control efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines environmental sensors (occupancy, ambient light) with the LED lighting fixture by mounting them on the heatsink, creating an integrated system that enables intelligent lighting control based on environmental conditions while avoiding separate standalone sensor systems
Solution Approach 2:
The heatsink serves multiple functions: it provides thermal management for the LED modules and simultaneously acts as a mounting structure for environmental sensors, enabling the fixture to perform both lighting and environmental sensing functions through a single integrated component
2Measurement precision
If sensors are permanently integrated into the lighting fixture, then measurement precision is improved, but ease of repair deteriorates
Solution Approach 1:
The sensor module is designed as a separate, removable component that can be independently accessed and replaced without replacing the entire lighting fixture, allowing sensors to be precisely integrated while maintaining ease of repair through modular design
3Adaptability or versatility
If a custom sensor integration system is designed for each fixture type, then adaptability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The heatsink is designed with a universal mounting structure that can accommodate environmental sensors across different LED fixture types, enabling a single standardized approach to sensor integration that works across multiple fixture configurations without requiring custom designs for each type

AI summary
A sensor module is integrated into a lighting fixture. The sensor module includes one or more environmental sensors and can be readily installed in or removed from the lighting fixture. In one embodiment, a heatsink of the lighting fixture is configured to receive the sensor module. Readings from the environmental sensors may be passed to control electronics associated with the lighting fixture and used to control the light output of the lighting fixture. The readings may also be passed on to other lighting fixtures, which may also use the readings to control their light output.
