Light Fixture Control Module Mounting Base Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light fixtures with only a vertical pole lack a convenient surface for mounting a control module, making electrical connections difficult during installation, especially at the top of the fixture.
Innovation Solution
A light fixture control module with a base that includes an inner and outer end, where the inner end is mounted to a vertical mounting base, and a bracket with a shell and sensor is coupled to the outer end, featuring a sensor connector to electrically connect with the fixture wire, facilitating control of the light element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a light fixture uses only a vertical pole structure, then the fixture structure is simple, but there is no convenient surface for mounting a control module and electrical connections become difficult
Solution Approach 1:
The patent divides the control module into separate components: a mounting base that attaches to the vertical pole, and a control housing that contains the sensor and electronics. This segmentation allows the mounting base to provide a stable mounting surface while the control housing remains accessible for electrical connections, resolving the contradiction between simple structure and ease of operation.
Solution Approach 2:
The patent transitions from a purely vertical pole structure to a three-dimensional mounting configuration by adding a mounting base that extends horizontally from the pole. This dimensional change creates a convenient surface for mounting the control module while maintaining the simplicity of the vertical pole structure.
2Ease of operation
If the control module is installed at the top of the light fixture, then mounting is straightforward, but electrical connection becomes difficult during field installation
Solution Approach 1:
The patent introduces a mounting base as an intermediary component between the vertical pole and the control module. This mounting base provides both a stable mounting surface and convenient access points for electrical connections, eliminating the difficulty of making electrical connections at the top of the fixture while maintaining straightforward mounting.
3Adaptability or versatility
If a bracket with shell and sensor is added to the base, then control functionality is enabled, but device complexity increases
Solution Approach 1:
The patent designs the mounting base to serve multiple functions: it provides structural support for the control module, creates a convenient mounting surface, and facilitates electrical connections. This multi-functionality reduces the need for additional components, thereby limiting the increase in device complexity while enabling control functionality.

AI summary
A light fixture control module (100) includes a base (110) that includes an inner end (112) and an outer end (114). The inner end (112) is mounted to a vertical mounting base (50) of a light fixture (10). The light fixture control module (100) includes a bracket (150) coupled to the outer end of the base. The bracket includes a shell (152) that has an inner chamber (154). The light fixture control module includes a sensor (200a, 200b) mounted to the shell of the bracket. The sensor has a sensor element (210), a sensor wire (220) transmitting a control signal from the sensor element, and a sensor connector connected to an end of the sensor wire. The sensor connector is configured to be electrically connected to a fixture wire of the light fixture to control operation of a light element of the light fixture.
