Solution Overview

Problem

Current lighting apparatuses face challenges in conveniently adjusting the light emergent angle due to mechanical limitations, leading to inadequate adjustment capabilities and adverse effects like stray light and glare, which affect visual quality.

Innovation Solution

A light distributing component with a wedge-shaped refractive lens and a clamp holding portion is introduced to deflect the light path, allowing for adjustable light distribution without extensive mechanical rotation, reducing internal space requirements and minimizing glare.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mechanical rotation is used to adjust light emergent angle, then light direction can be changed, but the adjustment capability is limited and causes stray light and glare

Engineering Contradiction:
Improvelight emergent angle adjustmentVSAvoidstray light and glare
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical rotation system with an optical system using a light distributing component. This component includes a light incident surface, a light emergent surface, and a light distributing surface that redirects light. By substituting mechanical adjustment with optical path control, the system achieves superior light direction control without the limitations and adverse effects of mechanical rotation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The light distributing component acts as an intermediary between the light emitting assembly and the external environment. It includes a light incident surface that receives light, a light emergent surface that emits light, and a light distributing surface that controls light direction. This intermediary structure enables precise light direction control without requiring mechanical rotation of the entire lighting apparatus.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If mechanical rotation is used to adjust light direction, then light path can be changed, but internal space requirements increase

Engineering Contradiction:
