Multi-angle Shifting Structure for Linear Lamps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current linear lamps have a fixed light-emitting angle, limiting their application and suffering from poor anti-glare effects due to inadequate light shielding.
Innovation Solution
A multi-angle shifting structure featuring at least two light-emitting units with different light-emitting angles, controlled by a driving module, and a grid lamp cup with anti-glare layers to enhance light distribution and reduce glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light-emitting angle is used in linear lamps, then the device complexity is reduced and manufacturing is simplified, but the adaptability and versatility of the lamp are limited
Solution Approach 1:
The linear lamp is divided into multiple independently controllable light-emitting units, each with different light-emitting angles. The driving module can separately control on/off and drive current of each unit, enabling flexible combination to achieve various light-emitting effects and angles without increasing overall structural complexity
Solution Approach 2:
The linear lamp structure is designed to perform multiple functions by combining different light-emitting units with various angles. A single lamp can produce multiple light-emitting effects by controlling different units, making the device universally applicable to different application scenarios without requiring separate lamps for each angle
2Object-affected harmful factors
If a light-emitting mask is used to reduce glare, then some anti-glare effect is achieved, but the anti-glare performance is insufficient and glare still occurs
Solution Approach 1:
The patent introduces a grid lamp cup structure with light shielding portions that block light from emitting in certain directions. By adding this dimensional light shielding element, the system effectively blocks glare-causing light paths while maintaining beneficial light distribution, significantly improving anti-glare performance beyond what a simple mask can achieve

AI summary
The present disclosure is applicable to the field of illumination technologies, and provides a multi-angle shifting structure and a linear lamp, wherein the multi-angle shifting structure includes a driving module, and at least two light-emitting units arranged side by side or in parallel, wherein each of the light-emitting units includes at least one light-emitting module (10, 20), each of the light-emitting units has a different light-emitting angle, and the driving module separately controls on and off and/or drive current of each of the light-emitting units; the linear lamp includes the multi-angle shifting structure as described above. The present disclosure can realize shifting between multiple light-emitting angles with one lamp, thereby overcoming the defect of a single angle of linear lamps, increasing diversity of application scenes and application manners of the linear lamps, realizing the function of multi-angle shifting of the linear lamps and saving the space, and shifting between multiple light-emitting angles can be controlled simply by switchover, which is simple and highly functional.
