Solar Disc Lamp Side Lighting via Internal Light Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor solar lamps have limited illumination range and increase in volume when designed to emit light from both the top surface and sides, leading to inefficient packaging and transportation due to the need for secondary light guides.
Innovation Solution
An outdoor solar disc lamp with a translucent lampshade, a base for fixing, a battery, and a solar panel, where a circular light panel with LEDs is positioned between the solar panel and the side translucent portion, allowing light to penetrate through both the top and side surfaces without a secondary light board, enhancing side lighting and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If inclined light guides are added around the lampshade to emit light from sides, then the illumination range is improved, but the volume of the overall solar outdoor light increases
Solution Approach 1:
The patent embeds multiple light guides within the lampshade structure itself. The light guides are integrated into the hollow interior space of the lampshade, allowing them to be nested within the existing volume rather than adding external components. This enables side lighting functionality while maintaining a compact overall volume.
Solution Approach 2:
The patent transitions from external light guides to internal light guides that utilize the vertical dimension within the lampshade. By positioning light guides at different heights and angles inside the hollow lampshade, the design achieves side illumination without increasing the external footprint or volume of the lamp.
2Illumination intensity
If secondary light boards are added to the bottom of the primary light board to enhance side lighting, then the side lighting effect is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent designs the light guides to serve multiple functions: they redirect light to the sides, provide structural support within the lampshade, and define the internal optical path. This multi-functionality eliminates the need for separate secondary light boards, reducing both device complexity and production cost while maintaining effective side lighting.
Solution Approach 2:
The patent merges the functions of primary and secondary light guides into a single integrated light guide system. The light guides are combined with the lampshade structure, creating a unified design that achieves both top and side illumination without requiring separate light boards, thereby simplifying the overall device and reducing manufacturing complexity.
3Ease of operation
If multiple light guides with certain length and divergent angle are used, then the light can be directed to surrounding area, but the volume increases and packaging becomes difficult
Solution Approach 1:
The patent nests the light guides within the hollow interior of the lampshade, allowing them to be stored in a compact configuration during packaging. The light guides can be folded or positioned vertically within the lampshade cavity, significantly reducing the volume required for packaging and transportation while maintaining their light-directing capability when assembled.

AI summary
An outdoor solar disc lamp includes a translucent lampshade mounted on a base, the translucent lampshade has a top translucent portion and a side translucent portion around the periphery of the top translucent portion, a solar panel is installed between the base and the translucent lampshade and above a battery, and a circular light panel surrounds the periphery of the battery and has a height lower than the solar panel, such that the circular light panel can emit light toward both the top translucent portion and the side translucent portion of the translucent lampshade.
