Lighting Apparatus Authentication Controller for Secure Power Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems that combine lighting apparatuses with electronic devices lack effective mechanisms for secure and efficient power management, leading to potential power wastage and safety concerns when detachably mounting different electronic apparatuses, particularly in ensuring only authorized devices receive power and maintaining system reliability.
Innovation Solution
A lighting system with a power supply circuit, light-emitting unit, mounting unit, and lighting-side controller that performs authentication processing before supplying power to the electronic apparatus, includes a voltage level adjustment unit to accommodate various voltage requirements, and integrates communication capabilities for interlocking operations with information processing apparatuses, allowing secure and efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power is supplied to the electronic apparatus as soon as it is mounted to the lighting apparatus, then the ease of operation is improved, but the reliability deteriorates due to power supply to unauthorized devices
Solution Approach 1:
The lighting-side controller performs authentication processing with the apparatus-side controller before supplying operating voltage to the apparatus function unit. This preliminary authentication action ensures that only authorized electronic apparatuses receive power, resolving the contradiction by adding a security check that does not prevent mounting but controls power delivery timing
2Ease of operation
If power is continuously supplied to the mounting unit, then the ease of operation is improved, but the energy consumption increases
Solution Approach 1:
The lighting-side controller supplies operating voltage to the apparatus-side controller periodically or on-demand to enable authentication, rather than maintaining continuous power supply. This periodic power delivery allows the system to be ready for operation while minimizing energy consumption during idle periods
3Reliability
If authentication processing is implemented, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The lighting-side controller and apparatus-side controller are designed to perform multiple functions: the lighting-side controller manages both light emission control and authentication/power supply control, while the apparatus-side controller handles both authentication responses and apparatus function control. This multi-functionality reduces overall system complexity by consolidating control capabilities

AI summary
A lighting apparatus includes a power supply circuit, a light-emitting unit, a mounting unit, and a lighting-side controller. The light-emitting unit is configured to drive light emission based on a power supply voltage generated by the power supply circuit. The mounting unit is configured to detachably mount an electronic apparatus including an apparatus-side controller and an apparatus function unit controlled by the apparatus-side controller. The lighting-side controller is configured to perform control to supply an operating voltage based on the power supply voltage to the apparatus-side controller of the electronic apparatus mounted to the mounting unit to perform authentication processing with the apparatus-side controller, and perform, based on a result of the authentication processing, control to supply the operating voltage based on the power supply voltage to the apparatus function unit.
