Solution Overview
Problem
Existing light fixtures face limitations in both optical and thermal control, as current techniques do not fully satisfy the need for efficient radiation management and heat dissipation, particularly in outdoor applications where moisture and environmental factors are a concern.
Innovation Solution
A light fixture design featuring a thermally conductive sleeve and support with adjustable positioning of a light emitting module, combined with a power supply unit and optically transparent lens, allows for enhanced thermal energy transfer and beam width adjustment through a rotatable mechanism, ensuring effective heat dissipation and optical control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a light emitting module is used in outdoor applications, then illumination function is achieved, but heat dissipation becomes difficult due to environmental constraints
Solution Approach 1:
The light fixture is divided into separate functional components: a moisture-sealed housing containing the light emitting module, and a thermally conductive sleeve for heat dissipation. This segmentation allows the optical component to be protected from moisture while the thermal management function is handled separately by the sleeve that extends outside the sealed environment.
Solution Approach 2:
A thermally conductive sleeve acts as an intermediary between the light emitting module (inside the sealed housing) and the external environment. The sleeve conducts heat away from the module while its outer surface is exposed to ambient air for dissipation, effectively mediating thermal transfer without compromising the moisture seal of the housing.
2Adaptability or versatility
If optical control is implemented using fixed structures, then manufacturing is simplified, but adaptability to different lighting conditions is reduced
Solution Approach 1:
The baffle is made adjustable rather than fixed, allowing it to be positioned at different distances from the light emitting module. This dynamic adjustment capability enables control over beam width and light distribution patterns, providing adaptability to various outdoor lighting conditions while maintaining a relatively simple overall structure.

AI summary
A housing has an internally-threaded opening that opens through an external surface. A support has external threads that engage the internal threads. Radiation-emitting structure on the support emits a beam of radiation that propagates to a location remote from the housing. At the location, the beam has a width that is a function of the position of the support within the housing. According to a different aspect, a housing has an internally-threaded opening that opens through an external surface, the housing including thermally-conductive material with the internal threads thereon. A support has external threads that engage the internal threads, the support including thermally-conductive material with the external threads thereon. Radiation-emitting structure is provided on the support, and the thermally-conductive material of the support carries heat from the radiation-emitting structure to the external threads.
