Lighting Fixture Dual-Mode Radio Infrared Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures that are not paired with a control apparatus are uncontrollable, and adjustors for lighting fixtures cannot function if they have not undergone frequency allocation, which is regarded as pairing, limiting individual control over unpaired fixtures.
Innovation Solution
A lighting fixture system that receives both radio and infrared commands, with a transceiver for radio commands and a receiver for infrared commands, and a controller that stores identification information to accept commands only from paired devices, allowing both paired and non-paired fixtures to be controlled through a pairing configuration mode that includes simple and manual pairing options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lighting fixture is paired with a control apparatus using ID-based pairing, then security against unknown remote controllers is improved, but controllability of non-paired fixtures deteriorates
Solution Approach 1:
The patent introduces an infrared remote controller as an intermediary device that can control lighting fixtures without requiring pairing. The infrared remote controller acts as a universal mediator that can issue commands to any fixture, while the radio remote controller provides secure paired control. This resolves the contradiction by providing two different control pathways: one secure (radio) and one universal (infrared).
Solution Approach 2:
The lighting fixture is designed to accept two types of remote control signals: radio commands from paired controllers and infrared commands from universal controllers. This multi-functionality allows the fixture to operate in both secured mode (when paired) and universal mode (when unpaired), resolving the contradiction between security and ease of operation.
2Ease of operation
If a lighting fixture accepts commands from any remote controller, then ease of operation is improved, but security against unknown controllers deteriorates
Solution Approach 1:
The lighting fixture dynamically switches between two operational states: paired state (accepting only radio commands from matched controllers) and unpaired state (accepting infrared commands from any controller). This dynamic behavior allows the system to adapt its security level based on whether pairing has been established, resolving the contradiction between security and ease of operation.
3Ease of operation
If infrared remote control is used for universal control, then ease of operation for non-paired fixtures is improved, but device complexity increases due to dual receiver support
Solution Approach 1:
The patent replaces the need for complex pairing mechanisms with a simpler infrared reception system. Instead of requiring complex authentication protocols for all control operations, the system uses infrared signals as a simple universal control layer that works without pairing, reducing overall system complexity while maintaining ease of operation.

AI summary
A lighting fixture includes a transceiver, a receiver, a storage, and a controller. The transceiver receives a radio command from a radio remote controller for operating the lighting fixture. The receiver receives an infrared command from an infrared remote controller for operating the lighting fixture. The storage stores identification information of the radio remote controller. The controller, if the identification information is stored in the storage, accepts a radio command that includes identification information same as the identification information stored in the storage, among radio commands received by the transceiver, and ignores the infrared command received by the receiver, and if no identification information is stored in the storage, accepts the infrared command received by the receiver.
