Recessed Air Purifier Ambient Lamp Layout for Glare and Water Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers with ambient lamps suffer from glare and are prone to damage due to direct light emission and exposure to water and physical impacts.
Innovation Solution
The air purifier design incorporates a shielded ambient lamp system with a lamp belt and lower housing arrangement, where the lamp belt is fixed in a recessed position, emitting light through a gap between the belt and the base, reducing glare and protecting the lamp from water and impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light source is directly mounted on the purifier surface, then the lighting function is achieved, but glare is produced and the lamp is vulnerable to damage
Solution Approach 1:
The patent introduces an ambient lamp structure that acts as an intermediary between the light source and the external environment. The lamp is embedded in a recessed cavity with a transparent cover plate, mediating the light emission to reduce direct glare while protecting the light source from water and physical damage. This intermediary structure resolves the contradiction by allowing lighting function while eliminating harmful effects.
Solution Approach 2:
The ambient lamp is nested within a recessed cavity in the purifier housing, with the light source embedded in the lamp belt and covered by a transparent cover plate. This nested arrangement allows the light to be emitted through multiple layers (lamp belt, cover plate, housing opening) which diffuses the light and reduces glare, while simultaneously protecting the light source from external harmful factors.
2Adaptability or versatility
If the ambient lamp is exposed on the purifier surface, then the lighting and atmosphere enhancement function is achieved, but the lamp is easily damaged by water ingress and physical impact
Solution Approach 1:
The ambient lamp is nested within a recessed cavity structure where the lamp belt is embedded in the housing and covered by a transparent cover plate. This nested arrangement protects the light source from water ingress and physical impact while still allowing light to pass through for atmospheric enhancement functions.
Solution Approach 2:
The transparent cover plate acts as a protective shell that seals the ambient lamp from the external environment. This thin film structure allows light transmission for atmospheric enhancement while providing reliable protection against water and physical damage, resolving the contradiction between versatility and reliability.
3Object-affected harmful factors
If the light source is shielded in a recessed position, then glare is reduced and protection is improved, but the lighting effectiveness may be compromised
Solution Approach 1:
The transparent cover plate serves as a light-transmitting barrier that allows effective illumination while reducing glare. The shielded recessed position combined with the transparent cover creates a controlled light emission path that maintains lighting effectiveness without the harmful direct glare of exposed light sources.
Solution Approach 2:
The transparent cover plate and recessed housing structure act as intermediaries that modify the light emission characteristics. They reduce direct glare by diffusing and redirecting light while still allowing sufficient illumination to pass through, resolving the contradiction between glare reduction and lighting effectiveness.
