Projector Light Source Module Fragment Containment

The bulb cover is segmented into multiple sections: a main cover body with fragment-blocking function, and separate heat dissipation channels. This segmentation allows the cover to block fragments while maintaining effective heat dissipation pathways, resolving the contradiction between fragment protection and thermal management

The patent introduces heat dissipation holes as intermediary structures that allow thermal energy to escape while the main cover body continues to block fragments. These intermediary channels mediate between the conflicting requirements of fragment containment and heat release

The patent extracts the light-blocking function from the fragment-absorbing function. Instead of using a single material to perform both tasks, the design separates these functions: the bulb cover structure handles fragment containment while dedicated light-blocking measures prevent light leakage, eliminating the contradiction present in the foaming rubber solution

Different regions of the bulb cover are designed with different properties: areas facing potential fragment trajectories are reinforced for containment, while areas exposed to light are designed with light-blocking characteristics. This local differentiation resolves the contradiction between fragment absorption and light reflection

The bulb cover is designed as a multi-functional component that simultaneously blocks fragments, manages heat dissipation, and provides structural support. By making the cover universal rather than adding separate components for each function, safety is improved without proportionally increasing device complexity

The patent merges the fragment-blocking function with the existing bulb cover structure rather than adding a separate protective component. This merging approach integrates safety features into the existing design, improving protection while minimizing increases in overall device complexity
