Solution Overview
Problem
The fixed shape design of reflection cups and TIR lenses in existing directional light-emitting systems makes it difficult to flexibly design and apply the ranges of light-emitting apertures as required, limiting the flexibility in achieving desired directional light emission.
Innovation Solution
A light-emitting system comprising a light source and a light-emitting structure made of transparent material with extension and light-adjusting portions, where the extension portions control the light-emitting range and the light-adjusting portions, disposed at specific angles, allow for adjustable light directionality, utilizing reflection and refraction principles for directional output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reflection cup or TIR lens is used to achieve directional light emission, then the light emission direction is controlled, but the light-emitting aperture range is fixed and cannot be flexibly adjusted
Solution Approach 1:
The light-emitting structure is divided into multiple light-emitting units, each with adjustable light-emitting apertures. This segmentation allows independent control of aperture ranges for each unit, enabling flexible adjustment of the overall light-emitting aperture without requiring a complete redesign of the optical structure.
Solution Approach 2:
The light-emitting apertures are designed to be adjustable rather than fixed. The aperture ranges can be dynamically changed to match different illumination requirements, transforming a static optical system into a dynamic one that adapts to varying application needs.
2Adaptability or versatility
If a reflection cup with fixed shape is used, then the manufacturing process is simplified, but the light-emitting aperture range cannot be flexibly designed
Solution Approach 1:
The reflection cup is segmented into multiple light-emitting units with standardized components. This segmentation allows the use of modular manufacturing processes where identical or similar components can be mass-produced and then assembled in different configurations to achieve various aperture ranges.
Solution Approach 2:
The light-emitting units are designed with universal interfaces and standardized structures that can be used across different applications. This multi-functionality allows the same basic component to serve multiple purposes by adjusting the aperture configuration, simplifying the manufacturing process while maintaining design flexibility.
3Adaptability or versatility
If TIR lens is used for directional illumination, then the light emission angle is controlled, but the aperture size is proportionally fixed and cannot be independently adjusted
Solution Approach 1:
The TIR lens system is divided into multiple independent light-emitting units. Each unit can have its aperture size adjusted independently without affecting the optical precision of other units. This segmentation decouples the aperture size parameter from the overall system dimensions.
Solution Approach 2:
Different regions of the light-emitting structure have different aperture characteristics optimized for their specific functions. This local quality approach allows precise control of aperture sizes in different areas while maintaining the required optical precision for directional illumination.

AI summary
A light-emitting structure and a light-emitting system with the same are provided. The light-emitting structure includes a plurality of extension portions (10) and a plurality of light adjusting portions (20), and the plurality of extension portions (10) and the plurality of light adjusting portions (20) are sequentially alternately connected; the plurality of extension portions (10) controls the light-emitting range of the light-emitting structure, and the plurality of light adjusting portions (20) is disposed at a predetermined angle with respect to an incident light direction to control a light-emitting direction. By application of the light-emitting structure of the present application, the size of the light-emitting aperture of the light-emitting structure can be designed according to the requirements of the actual illumination range, and the directional light emission according to the requirements for the direction of illumination is achieved. Therefore, it solves the problem with the prior art that the relatively fixed shape design of a reflection cup and a TIR lens makes it difficult to flexibly design and apply the ranges of light-emitting apertures of the reflection cup and the TIR lens as required.
