Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor lighting apparatus require high power, good heat dissipation, and waterproofing, but typical lenses are easily damaged by friction and collision during production, manufacturing, and transportation, affecting their optical performance.
Innovation Solution
A light source module comprising a heat sink, circuit board, lamp shade with recessed optical lenses, and a fixing member that securely attaches the lamp shade to the heat sink, preventing lens damage and ensuring good optical performance through the use of arc protrusions and recesses that reduce friction and enhance protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If typical lenses are used in outdoor lighting apparatus, then the lighting apparatus can provide high power and good heat dissipation, but the lenses are easily damaged by friction and collision during production, manufacturing and transportation
Solution Approach 1:
The patent inverts the conventional lens design by making the lens surface protrude outward instead of being recessed. This inversion allows the lens to be covered and protected by the lamp shade during handling and installation, significantly reducing friction and collision damage while maintaining optical performance in high-power outdoor lighting applications
2Ease of operation
If the lens protrudes outward for easier installation, then installation convenience is improved, but the lens becomes more susceptible to damage from friction and collision
Solution Approach 1:
The patent implements a nested structure where the lamp shade envelops and protects the lens. The lamp shade is designed to cover the protruding lens surface, creating a protective enclosure that shields the lens from friction and collision during handling, installation, and operation, while still allowing the lens to protrude for optimal optical performance
