PHOSPHOR WHEEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240345464 titled 'PHOSPHOR WHEEL
Simplified Explanation: The patent application describes a phosphor wheel with a substrate, phosphor layer, and a heat dissipation member with a protrusion and fins for efficient heat dissipation.
- The phosphor wheel includes a substrate with a phosphor layer on one surface and a heat dissipation member on the other.
- The heat dissipation member has a central protrusion and fins in the peripheral region for heat conduction.
- The protrusion creates a gap between the substrate and the heat dissipation member, allowing heat transfer to the fins.
- Two fins opposite each other in the rotation direction of the heat dissipation member aid in heat dissipation.
Key Features and Innovation:
- Efficient heat dissipation through the design of the heat dissipation member with a protrusion and fins.
- Enhanced thermal management for the phosphor wheel, improving overall performance and longevity.
Potential Applications:
- LED lighting systems
- Display technologies
- Automotive lighting
Problems Solved:
- Overheating of phosphor wheels leading to reduced performance and lifespan.
- Inefficient heat dissipation in high-power applications.
Benefits:
- Improved thermal management
- Extended lifespan of phosphor wheels
- Enhanced overall performance
Commercial Applications: The technology can be applied in various industries such as LED lighting, displays, and automotive lighting, where efficient heat dissipation is crucial for performance and longevity.
Questions about Phosphor Wheel Technology: 1. How does the protrusion in the heat dissipation member contribute to heat transfer efficiency? 2. What are the potential drawbacks of the fins design in the heat dissipation member?
Frequently Updated Research: Ongoing research focuses on optimizing the design of heat dissipation members for improved thermal management in phosphor wheels.
Original Abstract Submitted
a phosphor wheel includes: a substrate having a first main surface and a second main surface; a phosphor layer provided on the first main surface; and a heat dissipation member disposed opposite the second main surface. the heat dissipation member includes: a protrusion provided in a central part of the heat dissipation member; and a plurality of fins formed by lancing a plurality of regions in a peripheral region outside the central part. the protrusion provides a set gap between the substrate and the heat dissipation member and conducts heat from the substrate to the peripheral region. two fins among the plurality of fins are formed on sides of the corresponding region opposite each other in a rotation direction of the heat dissipation member.
