1Use of energy by moving object
If LED-based light fixtures are used to improve energy efficiency and light quality, then energy consumption is reduced and light output is improved, but control capability to maintain specific lighting parameters is insufficient
Solution Approach 1:
The fixture configuration module is pre-programmed with specific ranges for lighting parameters (such as color temperature and brightness) before installation. This preliminary configuration enables the fixture to automatically maintain desired lighting characteristics without requiring real-time manual adjustment, thus preserving ease of operation while achieving precise control.
Solution Approach 2:
The system incorporates sensors that continuously monitor actual lighting parameters and compare them against the pre-configured ranges. When deviations are detected, the control circuit automatically adjusts LED output to bring parameters back within the desired range, providing closed-loop feedback control that enhances parameter maintenance capability without adding operational complexity.
2Ease of operation
If control circuitry is added to LED light fixtures to enable parameter control, then lighting parameter control is improved, but device complexity increases
Solution Approach 1:
The patent combines the configuration module, control circuitry, and sensor array into an integrated system that works as a unified control unit. By merging these components rather than treating them as separate additions, the system achieves sophisticated parameter control while minimizing the increase in overall device complexity through functional integration.
Solution Approach 2:
The fixture configuration module is designed to control multiple lighting parameters (brightness, color temperature, timing) simultaneously using a single integrated control system. This multi-functional approach allows comprehensive lighting control without requiring separate control circuits for each parameter, thus reducing overall device complexity while maintaining enhanced control capability.
3Ease of manufacture
If fixed lighting parameters are used in LED fixtures, then manufacturing simplicity is maintained, but adaptability to different lighting needs is reduced
Solution Approach 1:
The system transitions from fixed, static lighting parameters to dynamically adjustable parameters through the fixture configuration module. The module allows lighting parameters to be changed based on different operational requirements, times of day, or environmental conditions, providing adaptability while maintaining manufacturing simplicity because the hardware platform remains the same—only the configurable parameters change.
Solution Approach 2:
The invention enables changeable lighting parameters (such as color temperature and brightness levels) without requiring different physical fixtures for different applications. By making parameters adjustable through software configuration rather than hardware changes, the system achieves versatility across multiple lighting scenarios while maintaining straightforward manufacturing processes for a standardized fixture design.

AI summary
A fixture configuration module comprises range control circuitry and fixture control circuitry. The range control circuitry is configured to store a range of a lighting parameter. The range identifies at least a subset of values of the lighting parameter supported by the light fixture to produce light. The fixture control circuitry is communicatively coupled to the range control circuitry and is configured to control the light fixture to produce the light in accordance with the range stored by the range control circuitry.
