Solution Overview
Problem
Conventional lighting devices do not effectively address air purification, particularly in terms of removing particulate matter and microbial contaminants from the air they heat up, despite generating air flows.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional filter is used in a lighting device, then air filtration is provided, but the filter does not effectively remove microbial contaminants and the air purification quality is insufficient
Solution Approach 1:
The filter combines metal substrate with antimicrobial coating to create a composite material that provides both mechanical filtration and antimicrobial action, effectively removing particulate matter and microbial contaminants from air
Solution Approach 2:
The filter utilizes a porous structure with randomly deformed threadlike elements that form non-linear pathways, maximizing contact between air and the antimicrobial surface while maintaining effective filtration
2Object-affected harmful factors
If air flows directly through a filter, then filtration occurs, but contact time between air and filter surface is insufficient for effective antimicrobial action
Solution Approach 1:
The filter employs randomly deformed threadlike elements that create non-linear, winding pathways instead of straight channels, forcing air to follow curved trajectories that maximize contact time and surface area interaction with the antimicrobial coating
Solution Approach 2:
The three-dimensional random deformation of threadlike elements creates a complex spatial network of pathways, transforming simple linear flow into multi-dimensional air circulation that enhances contact opportunities

Implementation Method 1
the lighting body of a lighting device in any case generates heat. The air in the vicinity of the lighting body heats up and generates air flows
Implementation Method 2
The air in the vicinity of the lighting body heats up and generates air flows. Typically the heated air tends to rise
Implementation Method 3
a lighting device with a filtering system able to exert, in addition to a mechanical filtering action, also an effective antimicrobial action
Implementation Method 4
the metal is treated with substances having antimicrobial properties which fill the pores formed in the superficial oxide layer

AI summary
The present invention relates to a lighting device comprising a main body (10), a lighting body (20) and an anodized metal filter (30), in which said metal comprises a superficial porous layer of an oxide of said metal comprising at least one antimicrobial substance. In one embodiment, the filter comprises a plurality of threadlike elements of said anodized metal, at least partially in non-permanent contact with each other, randomly deformed to form a plurality of non-linear pathways. The air to be treated passes through said filter owing to the effect of a difference in temperature and/or the action of a mechanical device. In other embodiments, the filter comprises a metal sheet with holes.
