Internet-Connected Lighting Control for Anticipatory Daylight Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems require integrated daylight sensors within the luminaire structure, leading to complex and inefficient local lighting control, as they can only react to current light conditions, resulting in fluctuating light emission and high energy consumption.
Innovation Solution
A lighting system with an Internet connection that receives external light information, allowing for decentralized data acquisition and control, using sensors to collect local luminaire information and external data such as weather forecasts to anticipate and adjust light output, optimizing energy consumption and light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If daylight sensors are integrated within the luminaire structure, then local lighting control is enabled, but device complexity increases and hardware requirements are higher
Solution Approach 1:
The patent extracts the daylight sensing function from the luminaire structure and places sensors in external locations (weather stations, centralized locations). The luminaire receives daylight information via Internet connection, separating the sensing function from the lighting function, thereby simplifying the luminaire structure while maintaining local lighting control capability
Solution Approach 2:
The patent introduces an intermediary system (Internet connection, data transmission network) between the external sensors and the luminaire. This mediator allows the luminaire to access external daylight information without physically integrating sensors, resolving the contradiction between obtaining local control data and maintaining simple device structure
2Reliability
If integrated sensors are used within luminaires, then local light conditions are detected, but energy consumption increases due to reactive control
Solution Approach 1:
The patent uses external sensors to detect daylight conditions in advance and transmits this information to luminaires before the lighting adjustment is needed. This preliminary detection allows the lighting system to proactively adjust light output based on predicted or current external conditions, avoiding the need for continuous reactive adjustments that consume energy
Solution Approach 2:
The system establishes a feedback loop where external daylight information is continuously monitored and transmitted to luminaires, which then adjust their light output accordingly. This feedback mechanism enables efficient energy consumption by synchronizing artificial lighting with actual external light conditions rather than operating continuously or reactively
3Adaptability or versatility
If decentralized sensor integration is implemented, then local control is achieved, but manufacturing complexity and installation difficulty increase
Solution Approach 1:
The patent makes the luminaire universal by equipping it with Internet connectivity to receive daylight information from various external sources (weather stations, centralized sensors, multiple locations). This multi-functional approach allows a single luminaire design to adapt to different local conditions without requiring physical modification or integration of local sensors, simplifying both manufacturing and installation
