Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaires with adjustable illumination angles face challenges in limited installation spaces, leading to interference and reduced adjustable range, and compromising heat dissipation performance.
Innovation Solution
An irradiation angle adjustment component with a light source and optical component mounted on a support, allowing for rotation and/or swinging relative to the support, without adjusting the heat sink volume, to achieve angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lamp head is made rotatable or swingable to adjust illumination angle, then the illumination angle adjustability is improved, but the spatial volume required for rotation increases
Solution Approach 1:
The lamp head is divided into two independent rotatable components: the optical component (lens) and the light source (LED module). This segmentation allows each component to rotate independently around the same axis, reducing the total spatial volume required for angle adjustment while maintaining full illumination angle adjustability.
2Volume of moving object
If the heat sink volume is reduced to decrease lamp head volume, then the overall volume is reduced, but the heat dissipation performance deteriorates
Solution Approach 1:
The heat sink is extracted from the rotatable lamp head structure and fixed to the mounting frame. This separation allows the heat sink to maintain its full volume for optimal heat dissipation while the rotatable components (optical component and light source) occupy minimal space, resolving the volume-heat dissipation contradiction.
3Volume of moving object
If the lamp head volume is reduced in limited installation spaces, then the installation space requirement is reduced, but the adjustable range of illumination angle is reduced
Solution Approach 1:
By segmenting the lamp head into independently rotatable optical component and light source, the patent achieves full illumination angle coverage with minimal spatial volume. The independent rotation capabilities allow the system to access all angular positions without requiring excessive space.
Solution Approach 2:
The patent utilizes rotational motion around the central axis to achieve angle adjustment in a compact configuration. By rotating components in the angular dimension rather than translating them linearly, the system maintains full adjustable range while minimizing spatial volume requirements.
Data Source
AI summary
The invention provides an illumination angle adjustment component and an angle-adjustable luminaire. The illumination angle adjustment component comprises a support, a light source and an optical component. The light source emits light that is at least partially incident on the optical component, and the light is re-directed and emitted through the optical component. The light source and the optical component are both mounted on the support, and at least one of the light source and the optical component is rotatable and/or swingable relative to the support to change an angle of emergence of the light emitted from the optical component. The illumination angle adjustment component can improve the universality and ensure the heat dissipation effect.
