Light Converter with Motorless Heat Dissipation for Projectors

A dust-proof film is introduced as an intermediary layer between the light-collecting lens and the substrate. This thin film maintains close contact to ensure effective heat dissipation while preventing dust particles from adhering to the optical surfaces, thus resolving the contradiction between dust-proofing and heat dissipation

A flexible dust-proof film is used to cover the light-collecting lens and fluorescent body. The film's thin structure allows heat to pass through effectively while providing a protective barrier against dust contamination, maintaining both optical efficiency and thermal management

The motor and rotation mechanism are completely removed from the system. Instead of rotating the fluorescent wheel, the patent uses stationary fluorescent bodies with enhanced thermal contact to the substrate, extracting the unnecessary mechanical components while maintaining cooling effectiveness

The fluorescent body itself serves the dual function of light conversion and heat dissipation by maintaining direct thermal contact with the heat sink substrate. The system uses the inherent thermal properties of the materials rather than active mechanical cooling, allowing the structure to self-regulate temperature

The patent applies different thermal management strategies to different regions: the fluorescent body maintains direct thermal contact with the substrate in critical heat-generating areas, while air circulation or heat sinks manage heat in less critical regions, allowing effective stationary heat dissipation

The system uses composite structures combining materials with different thermal properties - high thermal conductivity materials at the fluorescent body-substrate interface for efficient heat transfer, and heat sink materials with large surface areas for heat dissipation, achieving effective cooling without mechanical movement
