Solution Overview
Problem
Current LED lighting designs rely on complex lens structures to achieve light distribution, resulting in increased costs and volume, making it necessary to develop an LED lighting apparatus with a simple structure that can be manufactured at a low cost and have customizable light distribution.
Innovation Solution
A lighting apparatus featuring a transparent portion with a preset-shaped inner surface that reflects light emitted by an LED source, allowing for customized light distribution by adjusting the angle and shape of the inner surface, which can be either cambered or flat, and coated with reflective materials to optimize light reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lens structures are used to achieve light distribution, then light distribution function is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the light distribution function from the traditional lens component and transfers it to the transparent portion's inner surface through geometric shaping. By removing the separate lens element and integrating the light redirecting function directly into the transparent portion's geometry, the device complexity is reduced while maintaining the light distribution capability.
Solution Approach 2:
The patent merges the light distribution function with the transparent portion structure itself. Instead of having a separate lens component, the inner surface of the transparent portion is shaped to perform both structural and optical functions, combining multiple functions into a single integrated component.

Data Source
AI summary
A lighting apparatus and a method for manufacturing the same. A lighting apparatus is provided, including: a transparent portion including a first surface, a second surface and an edge connected to the first surface and the second surface, the edge including an inner surface with a preset shape; and a light source fixed on the transparent portion so that the inner surface receives light emitted by the light source and reflects it to at least one of the first surface and the second surface. The preset shape has a certain relationship with distribution of light emitted to the first surface and the second surface. The method for manufacturing just designs the preset shape during designing stage so as to satisfy requirements for distribution of the light emitted to the first surface and the second surface.
