Solution Overview
Problem
Existing luminaires with adjustable illumination angles face challenges in limited installation spaces, leading to interference and reduced adjustability, and compromising heat dissipation performance.
Innovation Solution
An irradiation angle adjustment component with a support, light source, and optical component, allowing at least one of the light source and optical component to be rotatable and/or swingable relative to the support, without adjusting the heat sink volume, to change the angle of emergence of light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lamp head is designed to be rotatable or swingable relative to the face ring, then the illumination angle can be adjusted, but the overall spatial volume of the lamp head increases, causing interference in limited installation spaces
Solution Approach 1:
The patent divides the lamp head into separate functional modules: the light source module (with LED beads and heat sink) and the optical component module (lens or reflector). These modules can be independently positioned and adjusted, allowing the illumination angle to be changed without requiring the entire lamp head to rotate or swing, thus reducing the spatial volume needed for adjustment.
Solution Approach 2:
Instead of rotating the entire lamp head in a single dimension, the patent enables adjustment by moving the optical component relative to the light source in multiple dimensions. The optical component can be positioned at different angles and distances from the light source, providing illumination angle adjustment without requiring large rotational space.
2Volume of moving object
If the heat sink is adjusted to reduce the overall volume of the lamp head, then the spatial requirement for angle adjustment is reduced, but the heat dissipation performance is significantly affected
Solution Approach 1:
By separating the heat sink from the optical component, the patent allows the heat sink to be optimized for heat dissipation without compromising the optical adjustment mechanism. The light source module with its heat sink can be compactly designed while the optical component module provides the adjustment functionality, resolving the conflict between volume reduction and heat dissipation performance.

AI summary
The invention provides an illumination angle adjustment component and an angle-adjustable luminaire. The illumination angle adjustment component comprises a support (800), a light source (400) and an optical component (300). The light source (400) emits light that is at least partially incident on the optical component (300), and the light is re-directed and emitted through the optical component (300). The light source (400) and the optical component (300) are both mounted on the support (800), and at least one of the light source (400) and the optical component (300) is rotatable and/or swingable relative to the support (800) 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.
