Curved Lighting Base Body for Dust Shedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices with plate-shaped base bodies and vertical cooling ribs suffer from dust and dirt clogging, leading to reduced cooling efficiency and increased maintenance costs, especially in high-ceilinged environments like exhibition halls.
Innovation Solution
A lighting device with a plate-shaped base body featuring a conical or similarly shaped upper side that directs dust, dirt, and contaminants towards the outer circumference for easy discharge, combined with a cooling element and a detachable supporting frame, and a coating or surface structure that prevents adhesion and promotes water repellency, ensuring efficient cooling and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling fins are arranged vertically on a plate-shaped base body, then cooling efficiency is improved, but dust and dirt accumulation occurs leading to reduced cooling performance over time
Solution Approach 1:
The base body is designed with a curved, dome-shaped upper surface instead of a flat plate. This curvature causes dust and dirt to slide off the surface due to gravity, preventing accumulation on the cooling fins while maintaining vertical fin arrangement for effective cooling
2Area of stationary object
If the lighting device is installed in high-ceilinged spaces, then illumination coverage is improved, but maintenance and cleaning become more difficult and costly
Solution Approach 1:
The curved base body surface automatically sheds dust and dirt through gravitational force, providing self-cleaning functionality. This eliminates the need for manual cleaning operations, making the device suitable for high-ceilinged spaces where maintenance would otherwise be difficult and expensive
3Temperature
If regular cleaning and maintenance are performed, then cooling efficiency is maintained, but operational costs and time investment increase significantly
Solution Approach 1:
The curved surface design enables automatic dust and dirt removal through gravity, providing continuous self-cleaning without human intervention. This maintains optimal cooling efficiency throughout the device's operational life while eliminating maintenance time and associated costs

Implementation Method 1
the upper side of the plate-shaped base body is in cross-section approximately conical, conical, cone-shaped, frustoconical, convex, hemispherical or hemispherical, cup-shaped, pot-shaped or bowl-shaped, such that dust striking the upper side, Dirt or other contaminants and/or incident water or similar media are guided in the direction of its longitudinal axis towards its outer circumference and can be discharged via the outer circumference
Implementation Method 2
A cooling element is arranged on the base body, comprising cooling fins that extend essentially perpendicularly from the top of the base body and from the outer circumference of the base body in the direction of its longitudinal axis
Implementation Method 3
