Illumination Setting Memory for Automatic Light State Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination devices with liquid crystal light adjustment elements require manual re-setting of electric signals each time power is turned on to achieve the same use state as previously set, which is inconvenient.
Innovation Solution
An illumination control device with a storage that stores setting information for light emitters and a controller that writes and reads this information when power is turned off/on, allowing the device to maintain the previous use state automatically.

Engineering Contradiction Analysis
1Ease of operation
If manual re-setting of electric signals is required each time power is turned on, then the liquid crystal light adjustment element can be controlled, but user convenience deteriorates and operation time increases
Solution Approach 1:
The controller stores the electric signal settings in a storage device before power is turned off. When power is restored, the controller automatically retrieves and applies the stored settings without requiring user intervention, thus performing the re-setting action in advance and eliminating the need for manual reconfiguration.
Solution Approach 2:
The illumination device performs self-service by automatically restoring its previous operating state through the controller reading stored electric signal values from the storage device and applying them to the liquid crystal light adjustment element, without requiring external user input or manual adjustment.
2Ease of operation
If setting information is stored and automatically restored, then user convenience is improved, but device complexity increases due to additional storage and control functions
Solution Approach 1:
The controller performs multiple functions: it controls the liquid crystal light adjustment element during normal operation and simultaneously manages the storage device to save and restore electric signal settings. This multi-functionality allows the same component to handle both operational control and memory management, reducing the need for separate dedicated components.
Solution Approach 2:
The system changes the operational parameters of the liquid crystal light adjustment element by applying stored electric signal values. The controller modifies the voltage or signal parameters supplied to the liquid crystal element based on pre-stored settings, enabling automatic restoration of illumination states without physical reconfiguration.

AI summary
An illumination control device includes a storage that is non-transitory and stores setting information for controlling a light emitter configured to emit light, and a controller that writes the setting information as of then to the storage when a request for writing the setting information is input and reads the setting information from the storage when a request for reading the setting information is input. The light emitter is controlled based on the setting information read by the controller.
