Luminaire Side Switch Control for Accessible CCT Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional luminaires are inconvenient for users to adjust Correlated Color Temperature (CCT), brightness, and color due to control switches being inaccessible or requiring dismounting from the ceiling for adjustment.
Innovation Solution
A controller with a switch assembly on the luminaire's side, allowing for convenient adjustment of CCT, brightness, and color through toggle, button, or touch switches, enabling control signals to be sent directly to the luminaire's control board without dismounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control switch is provided on the back of the Recess Can (RS), then the luminaire can be mounted into the ceiling aperture in a recessed manner, but the switch becomes unavailable for the user to adjust CCT and brightness
Solution Approach 1:
Instead of placing the switch on the back of the luminaire body (traditional approach), the patent inverts the placement by positioning the switch assembly on the front surface of the luminaire, specifically on the diffuser or holder where the light outlet is located. This inversion makes the switch accessible to users after installation while maintaining the recessed mounting capability.
Solution Approach 2:
The patent transitions the switch from a hidden rear-position (three-dimensional space behind the luminaire) to a visible front-position on the diffuser or holder (surface dimension). This dimensional relocation ensures the switch remains accessible to users after the luminaire is mounted in the ceiling aperture.
2Ease of operation
If the luminaire is mounted under the ceiling with the can, then the luminaire structure is stable, but the user must separate the luminaire from the can to adjust CCT, brightness or color through a toggle switch on the back
Solution Approach 1:
The patent pre-positions the switch assembly on the front surface of the luminaire (diffuser or holder) before installation, so that after the luminaire is mounted under the ceiling, the switch is immediately accessible to users without requiring any disassembly or separation from the can. This preliminary placement eliminates the need for subsequent separation operations.
3Ease of operation
If the switch assembly is provided on the light outlet surface or diffuser, then the user can adjust CCT, brightness and color conveniently after installation, but the switch assembly occupies space on the front surface
Solution Approach 1:
The patent applies the switch assembly to a specific local area on the front surface (diffuser or holder near the light outlet) rather than distributing control elements across the entire luminaire surface. This localized placement provides accessibility while minimizing the overall area occupied by control components.

AI summary
Provided is a controller and a luminaire having the controller. The controller is provided in the luminaire, and may include a switch assembly provided on a side where a light outlet of the luminaire is located and configured to receive a selecting signal that is input from the outside, and a control board connected with the switch assembly and configured to generate a corresponding control signal on the basis of the selecting signal, so as to control a plurality of light sources of the luminaire to form at least two types of Correlated Color Temperatures (CCT), brightness and/or colors respectively. By the disclosure, the problem that it is hard for a user to adjust the CCT, the brightness and/or the color of the luminaire in the prior art is solved, and operating convenience of the user is improved.
