Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting lamps, such as those with LED light sources, lack adjustability in light direction, resulting in uniform but unfocused light distribution that cannot be tailored to specific illumination needs, limiting their effectiveness in areas requiring more focused light.
Innovation Solution
An angle-adjustable lamp design featuring rotatably connected heat sinks and light-transmitting covers around a central axis, allowing for adjustable light exit angles by rotating the heat sinks, which are symmetrically disposed around the lamp body and equipped with connecting rods and lugs for secure positioning, enabling the formation of various light sources like planar, elevation, or multi-faceted light distributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED light sources are arranged in a corn-shaped arrangement to achieve 360° light output, then light distribution uniformity is improved, but light directionality and focus are lost
Solution Approach 1:
The lamp is divided into multiple independent light-emitting modules (six rectangular panels and a circular panel), each with its own LED light sources. These modules can be independently adjusted or removed, allowing selective orientation of light beams while maintaining overall 360° coverage. This segmentation enables both uniform distribution and directional control.
Solution Approach 2:
The lamp introduces adjustable positioning mechanisms that allow the light-emitting modules to be dynamically repositioned and reoriented. The modules can be adjusted to different angles and positions, transforming the static uniform 360° emission into a dynamic system that can provide focused directional light when needed while maintaining overall uniformity.
2Device complexity
If fixed light emission structure is used to maintain simple design, then device complexity is reduced, but adjustability for different illumination needs is limited
Solution Approach 1:
The lamp structure is segmented into modular components (lamp holder, drive circuit board with six rectangular panels, circular panel) that can be independently adjusted or repositioned. This modular design maintains relative simplicity while enabling adjustability, as each module can be manipulated separately without affecting the entire structure.
Solution Approach 2:
The lamp incorporates adjustable positioning mechanisms that allow the light-emitting modules to be dynamically repositioned. The modules can be rotated, tilted, or repositioned to different angles, transforming a static structure into a dynamic adjustable system that adapts to different illumination requirements while maintaining structural simplicity.

Function Achieved in This Case
Enables flexible adjustment of light irradiation to specific areas, enhancing illumination where needed, such as in exhibition halls, by altering the angle of light transmission, while maintaining 360° light output.
Implementation Method 1
Each of the plurality of light-transmitting covers is disposed on a side of a corresponding one of the plurality of heat sinks facing away from the lamp body. When the plurality of heat sinks are rotated around the plurality of connecting rods, an angle between each of the plurality of light-transmitting covers and the lamp body is correspondingly changed, so that a light exit angle of light transmitted through each of the plurality of light-transmitting covers is correspondingly changed.
Implementation Method 2
The angle-adjustable lamp comprises a lamp body, a plurality of heat sinks, a plurality of connecting rods, and a plurality of light-transmitting covers.
