Hemispherical Adjusting Structure for Lamp Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamp adjusting devices have a complex structure and limited adjustable angle, making it difficult to effectively adjust the irradiating angle of lamps.
Innovation Solution
A hemispherical adjusting structure comprising a housing, an adjusting unit, and a driving device, where the adjusting unit includes an inner and outer movable member connected through a through hole in the housing, allowing for spherical movement and increased angle adjustment range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional adjusting device with middle ring and two perpendicular shafts is used, then the lamp structure is stable, but the device complexity increases and the adjusted angle range decreases
Solution Approach 1:
The adjusting device is segmented into a rotating assembly (with rotating member and reflecting member) and a fixed assembly (with housing and mounting structure). This segmentation allows the rotating assembly to independently rotate within the fixed assembly, enabling angle adjustment without requiring complex multi-shaft mechanisms. The segmentation simplifies the overall structure while achieving the desired angular adjustment capability.
2Device complexity
If a conventional adjusting device with multiple shafts is used, then the structural stability is maintained, but the device complexity increases
Solution Approach 1:
Multiple functional components are merged into a compact rotating assembly. The rotating member, reflecting member, and associated mounting structures are integrated into a single rotating unit that rotates as one cohesive assembly within the fixed housing. This merging reduces the number of separate shafts and connection points needed, simplifying the device structure while maintaining structural stability through the rigid integrated design.

AI summary
A hemispherical adjusting structure includes a housing, an adjusting unit, a light source module and a driving device. The housing has a through hole. The light source module is mounted in the adjusting unit. The driving device drives the adjusting unit to move along a spherical direction of the housing. The adjusting unit includes an inner movable member and an outer movable member. The inner movable member is located inside of the housing and includes a receiving portion and an abutment. The outer movable member is located outside of the housing and includes a mounting stud and an extension. The mounting stud extends through the through hole and is inserted into the receiving portion. Thus, the adjusting unit is moved along the spherical direction of the housing so as to adjust the irradiating angles of the lamp.
