Electronic Visual Distress Signaling With Heat Dissipation

The patent replaces pyrotechnic (chemical/mechanical) flare systems with an electronic LED-based optical signaling system. The electronic distress light uses electroluminescence from LED elements to generate visible and infrared light, eliminating combustion-based pyrotechnics while maintaining distress signaling functionality. This substitution resolves the contradiction by providing indefinite service life through replaceable rechargeable batteries and eliminating safety/environmental hazards associated with pyrotechnic materials

The patent changes the fundamental operating parameters from chemical combustion to electronic electroluminescence. The optical output is generated through LED elements driven by electronic circuits with可控 brightness and flashing patterns. This parameter change enables continuous operation limited only by power source duration rather than chemical stability, resolving the service life versus safety contradiction

The patent introduces a heat sink assembly as an intermediary thermal management component between the high-power LED elements and the device housing. The heat sink collects heat generated by the electromagnetic radiation emitting elements and dissipates it to the ambient environment through its external surfaces, enabling high-intensity optical output while maintaining safe operating temperatures

The patent extends thermal management into the spatial dimension by providing three-dimensional heat dissipation surfaces on the heat sink assembly. The heat sink structure provides external surfaces exposed to ambient air for convective and radiative heat transfer, creating additional thermal exchange pathways that enable high-power LED operation without excessive temperature rise
