1Volume of moving object
If small LED-based lighting devices are used, then device size is reduced, but heat dissipation capability deteriorates due to limited heat dissipation surfaces
Solution Approach 1:
The patent merges the connector plug with a heat sink, combining the electrical connection function and heat dissipation function into a single integrated component. The heat sink is directly formed as part of the connector plug body, creating a unified structure that simultaneously provides electrical contact and thermal management for small LED lighting devices
Solution Approach 2:
The connector plug is designed to perform multiple functions: electrical power transfer, data communication, and heat dissipation. By integrating the heat sink functionality into the connector plug, the same component serves both electrical and thermal management purposes, eliminating the need for separate heat dissipation structures in small lighting devices
2Temperature
If heat dissipation surface area is increased, then heat dissipation capability is improved, but device complexity increases
Solution Approach 1:
The heat dissipation function is merged with the existing connector plug structure rather than adding a separate heat dissipation component. The heat sink is formed as an integral part of the connector plug, utilizing the same material and manufacturing process, thereby avoiding increased device complexity while still providing enhanced heat dissipation capability
Solution Approach 2:
The connector plug material is selected or modified to have high thermal conductivity, changing the thermal parameter of the existing structure. By modifying the material properties or thermal characteristics of the connector plug itself, the heat dissipation capability is enhanced without adding complex structural elements
