Separate Illuminance Sensor Setting Unit for Ceiling Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing lighting control systems, setting the address for an illuminance sensor and operation illuminance for lighting apparatus is cumbersome, particularly when the sensor is mounted on a ceiling, as it requires approaching the ceiling for operation.
Innovation Solution
An illuminance sensor setting device with a separate setting unit connected via a transmission signal line, allowing for centralized control and simplifying the setting of illuminance sensor addresses and control addresses for lighting apparatus, enabling the setting unit to be placed conveniently away from the ceiling, such as on a wall, and facilitating the operation of setting the illuminance sensor address and control address.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the illuminance sensor and setting unit are integrated, then the device structure is simplified, but it becomes necessary to approach the ceiling for setting operations
Solution Approach 1:
The system is divided into two separate functional units: the illuminance sensor unit (attached to the ceiling) and the setting unit (placed elsewhere). This segmentation allows the sensor to remain in its optimal ceiling position while the setting unit can be operated from any location via network connection, resolving the contradiction between structural simplicity and operational convenience.
Solution Approach 2:
A network communication system acts as an intermediary between the illuminance sensor and the setting unit. This mediator enables remote setting operations by transmitting configuration data and control signals over the network, eliminating the need for physical proximity to the ceiling-mounted sensor.
2Ease of operation
If the setting unit is placed away from the ceiling, then setting operations are easier, but the transmission signal line complexity increases
Solution Approach 1:
The setting unit is designed to communicate with the illuminance sensor through a standard network infrastructure that can carry multiple types of traffic (data, control signals, power). This multi-functional approach allows the same transmission medium to handle both sensor data transmission and setting operations, reducing overall system complexity despite the distributed architecture.

AI summary
An illuminance sensor setting device includes: an illuminance sensor that outputs a signal for switching a lighting apparatus, and a setting unit that performs setting of the illuminance sensor. The illuminance sensor and the setting unit are provided separately from each other, and are connected to signal lines. The setting unit has a configuration to set a sensor address of the sensor, a control address of the lighting apparatus, and an illuminance reference for switching the lighting apparatus. The setting unit transmits to the signal line the setting signal and the sensor address. Thus, even if the illuminance sensor is provided on, for example, the ceiling in the vicinity of the lighting apparatus, the setting unit can be provided at any place, such as a wall, where the setting unit can be easily operated, and work for settings is facilitated.
