Ceiling Fan Light Casing with Recessed LED Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans with integrated lamps cause glare and fail to showcase the casing's color effectively at night due to unidirectional light emission and lack of visual appeal.
Innovation Solution
A ceiling fan upper light system featuring a light casing with opaque seats, light-pervious side walls, shielding plates, and an LED light-emitting module that emits light through a recessed groove, allowing the side walls to display color-changing light patterns and reducing glare by controlling light irradiation direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional lamp with light bulb and lampshade is used, then the lamp emits light downward and laterally, but the light dazzles the user and causes discomfort
Solution Approach 1:
The light casing is divided into multiple functional components: opaque seats for structural support, light-pervious side walls for controlled light transmission, and shielding plates for glare prevention. This segmentation allows each component to perform its specific function optimally while working together to resolve the glare issue.
Solution Approach 2:
Different parts of the light casing have different optical properties: the side walls are made of light-pervious material to allow light transmission, while the seats and shielding plates use opaque materials to block and direct light. This local differentiation of material properties enables precise control over light behavior to eliminate glare.
2Device complexity
If the ceiling fan casing has a fixed color, then the structure is simple, but the casing cannot be clearly seen and appreciated at night
Solution Approach 1:
The LED light-emitting module serves multiple functions: it provides general illumination, displays the casing's color, and creates visual appeal through color-changing capabilities. This multi-functionality allows a single component to address both the simplicity of structure and the need for visual visibility.
Solution Approach 2:
The LED light-emitting module can change light colors, allowing the ceiling fan casing to display different colors and be visually appreciated at night. This color-changing capability transforms the static, single-color casing into a dynamic, multi-color display without complicating the basic casing structure.
3Device complexity
If LED light-emitting diodes are placed directly in the light casing, then the structure is simple, but light irradiates directly outside causing glare
Solution Approach 1:
The shielding plate acts as an intermediary element between the LED light-emitting diodes and the external environment. It blocks direct light irradiation while allowing the light to illuminate the casing, thereby eliminating glare without requiring a complex light module structure.
Solution Approach 2:
The groove structure recesses the LED light-emitting diodes into a different spatial dimension within the light casing. This dimensional arrangement ensures that the diodes do not extend outward, preventing direct light exposure while maintaining structural simplicity.

AI summary
A ceiling fan upper light includes a light casing. The light casing has at least one side wall made of a light-pervious material. At least one shielding plate made of an opaque material is annularly disposed inside the light casing. At least one groove is annularly disposed inside the light casing. The at least one groove is located between the at least one side wall and the at least one shielding plate. A plurality of light-emitting diodes is annularly disposed inside the light casing. The light-emitting diodes are located in the at least one groove. The light-emitting diodes do not extend out of the at least one groove. The light-emitting diodes emit light toward the opening of the groove, so as to prevent the light from directly irradiating the outside of the at least one side wall, so that the at least one side wall displays the light color of the light-emitting diodes.
