Solution Overview
Problem
Existing lighting systems require separate mounting and wiring for sensing elements, increasing complexity and overhead in implementing ambient light sensing functions, particularly for automatic lighting control.
Innovation Solution
A lighting arrangement that integrates a sensor element in parallel with the light source arrangement, using the same terminal arrangement for connection to a driver, allowing for ambient light measurement through a measuring system that monitors the discharge characteristics of the light source when turned off, reducing the need for additional contacts and wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing elements are separately connected with additional mounting and wiring, then sensing function can be implemented, but device complexity increases
Solution Approach 1:
The patent combines the sensing element with the light source arrangement by mounting the sensing element directly on the circuit board at a defined position relative to the LED modules, allowing both lighting and sensing functions to share the same physical platform and terminal arrangement, thereby eliminating separate mounting and wiring requirements
Solution Approach 2:
The terminal arrangement is designed to serve dual purposes: it connects both the light source arrangement for lighting operation and the sensing element for ambient light detection, allowing a single interface to handle multiple functions without requiring additional contacts or wiring
2Adaptability or versatility
If separate contacts to driver are used for sensing elements, then sensing signal can be transmitted, but device complexity increases
Solution Approach 1:
The terminal arrangement serves multiple functions by connecting both the light source arrangement and the sensing element through the same terminals, allowing the driver to control lighting while simultaneously receiving sensing signals without requiring additional contacts
3Adaptability or versatility
If ambient light sensing is implemented with dedicated opening, then ambient light can be received, but device complexity increases
Solution Approach 1:
The sensing element is integrated into the existing luminaire structure by mounting it on the circuit board at a defined position, eliminating the need for dedicated openings while maintaining ambient light reception capability through the same physical structure that houses the light sources

Data Source
AI summary
A lighting arrangement has a lighting module with a sensor element in parallel with a light source arrangement between module terminals. A measuring system is provided for measuring, at the module terminals, a signal which is dependent on the sensor element when the light source arrangement is turned off. Thus, sensing is integrated into or connected to a lighting module, such as LED module.
