Display Light Source Package Thermal Management

The patent applies this principle by integrating a heat radiator directly into the light source package housing. The housing structure includes a heat transfer portion that contacts the light converter and a heat radiation portion that dissipates heat to the surroundings. This converts the harmful heat generation into a manageable thermal flow, allowing the light sources and converters to operate efficiently while preventing overheating damage.

The patent uses an expansion member as an intermediary between the heat transfer portion and the heat radiation portion. This expansion member enhances the heat transfer area and facilitates efficient heat conduction from the light converter through the housing to the external environment, acting as a thermal mediator that prevents heat accumulation at critical points.

The patent merges the heat radiator with the light source package housing into a single integrated structure. The housing includes both a heat transfer portion that contacts the light converter and a heat radiation portion that dissipates heat externally. This integration eliminates the need for separate heat sinking components, reducing assembly steps and structural complexity while maintaining effective heat radiation.

The light source package housing serves multiple functions: it provides mechanical support for the light converter, acts as a heat transfer pathway, and functions as a heat radiation structure. This multi-functionality reduces the number of separate components needed, simplifying the overall device structure while achieving effective thermal management.
