Reflective Slide Glare Reduction Lighting Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting apparatuses for external environments, such as pathway and garden lighting, often require anti-glare screens in the side walls, which can obstruct the light beam and complicate assembly and reliability, while also being prone to moisture issues and dirt accumulation.
Innovation Solution
A lighting apparatus design featuring a separate main body and lighting head with a reflective slide that directs light radially without anti-glare screens, using a hidden fixing mechanism and a protective plate to ensure unobstructed light emission and improved durability, incorporating a knurled, opaque reflective surface for diffusion and glare reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an anti-glare screen is provided in the side wall of the body, then glare is reduced, but the light beam is obstructed and the structure becomes more complex
Solution Approach 1:
The anti-glare function is extracted from the side wall and relocated to the reflective slide surface. The reflective slide with knurled opaque surface provides glare reduction without requiring separate anti-glare screens in the side walls, thus simplifying the overall structure while maintaining the glare reduction effect.
Solution Approach 2:
The reflective slide serves multiple functions: it reflects light radially from the light source, provides glare reduction through its knurled opaque surface, and eliminates the need for separate anti-glare screens. This multi-functionality reduces structural complexity while achieving the same harmful factor mitigation.
2Object-affected harmful factors
If an anti-glare screen is provided in the side wall, then glare is reduced, but assembly and reliability are complicated and moisture/dirt issues arise
Solution Approach 1:
The anti-glare functionality is extracted from the side wall assembly and integrated into the reflective slide that is already positioned in the light path. This eliminates the need for separate anti-glare screen components that would be exposed to external moisture and dirt, thereby improving reliability.
Solution Approach 2:
The reflective slide acts as an intermediary element that combines light reflection and glare reduction functions. By positioning this component in the light path where it can serve both purposes, the design avoids adding vulnerable components to the side walls that would be exposed to environmental factors.
3Ease of manufacture
If a separate main body and lighting head design is used, then assembly is simplified, but mechanical connection complexity increases
Solution Approach 1:
The fixing mechanism is merged with the head support neck structure. The fixing means are integrated into the neck portion that connects the lighting head to the main body, creating a unified connection structure that simplifies both manufacturing and assembly while maintaining mechanical robustness.
4Ease of repair
If the light source is housed in a separate lighting head, then maintenance is facilitated, but the connection structure becomes more complex
Solution Approach 1:
The connection structure is merged with the head support neck, which serves both as a mechanical support and as an integrated fixing mechanism. This unified structure facilitates maintenance by providing a clear separation between the replaceable lighting head and the fixed main body, while the integrated fixing means simplify the connection without adding complexity.

AI summary
Lighting apparatus, comprising a main body having a side wall extending around a longitudinal body axis from a base that is suitable for being fixed to the ground, and a lighting head that is connected to said main body. The main body has an upper portion that extends from the side wall and forms, at least in a peripheral sector, a reflective slide that is suitable for reflecting the light generated by the lighting head. The lighting head houses a light source suitable for projecting a beam of light downwards, above the reflective slide.
