Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beacon lights using incandescent bulbs require frequent maintenance due to short lifespan, while LED-based systems suffer from uneven light distribution, necessitating complex and costly solutions to achieve 360° and vertical light coverage for effective obstruction warning.
Innovation Solution
A beacon light and lens system featuring a Fresnel lens configuration and a base with a light emitting diode assembly, providing a 360° horizontal and controlled vertical light distribution with minimal stray light, using a base with a metallic or synthetic material construction for weather resistance and heat dissipation, and secure mechanical fastening for easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If incandescent bulbs are used in beacon lights, then even light distribution is achieved, but the bulb lifespan is short requiring frequent maintenance
Solution Approach 1:
The patent changes the light source parameter from incandescent bulb to LED, and introduces a Fresnel lens to modify the light distribution pattern. The Fresnel lens refracts and redirects LED light to achieve even 360-degree horizontal and vertical distribution, resolving the contradiction between lifespan and light distribution quality.
2Duration of action of stationary object
If LED light sources are used in beacon lights, then lifespan is extended, but light distribution becomes uneven requiring complex mirror systems
Solution Approach 1:
The Fresnel lens acts as an intermediary optical element between the LED light source and the surrounding environment. It captures light from the point-source LED and redistributes it uniformly in all directions, eliminating the need for complex mirror systems while maintaining the long lifespan advantage of LEDs.
3Illumination intensity
If mirror systems are used to distribute LED light, then light distribution is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the light distribution function from complex mechanical mirror systems and consolidates it into a single Fresnel lens component. This simplifies the optical system while achieving the same 360-degree light distribution effect, reducing both complexity and cost.
