Panel Light Night Light Diffusion Ring Micro-Lens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current panel lights with night light functions have a granular sensation and color partition due to the light-emitting beads, limiting their applicability and user experience.
Innovation Solution
The panel light design incorporates a diffusion ring and scattering micro-lens ring within the night light surface ring, diffusing and reflecting light rays from the night light bar to create a mixed light effect, eliminating the granular sensation and color partition, while ensuring effective heat radiation through an exposed radiating rib and hidden trunking structure for electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If lamp beads are used for night light function, then night light effect is achieved, but granular sensation and color partition occur
Solution Approach 1:
A diffusion ring is introduced as an intermediary component between the night light bar (containing lamp beads) and the night light surface ring. This diffusion ring scatters and uniformizes the light from the discrete lamp beads, eliminating the granular sensation and color partition while preserving the night light effect. The diffusion ring acts as a mediator that transforms the problematic discrete light sources into a uniform light field.
2Adaptability or versatility
If separate surface components are used for main light and night light functions, then functional requirements are met, but device complexity and manufacturing cost increase
Solution Approach 1:
The main surface ring is designed to serve dual functions: it acts as the light-emitting surface for the main light bar during daytime operation, and as the night light surface ring during nighttime operation. This multi-functional design eliminates the need for separate surface components for each lighting mode, reducing device complexity and manufacturing cost while meeting all functional requirements.

4Temperature
If heat radiation structure is exposed, then heat dissipation effectiveness is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The heat radiation structure (radiating ribs) is nested within the main surface ring, specifically arranged in the hollow annular cavity. This nesting arrangement allows the heat dissipation structure to be hidden from external view, maintaining aesthetic appearance, while still effectively conducting and radiating heat from the light bars. The radiating ribs are positioned such that they perform their thermal function without compromising the visual quality of the panel light surface.
