Fused Fiberoptic Rod Light Engine for Heat Management

The patent replaces the traditional incandescent lamp with a light emitting diode (LED) system. This substitution eliminates the filament that generates excessive heat, thereby maintaining high illumination intensity while preventing heat-related damage to fiber optic cables. The LED's electroluminescence mechanism directly converts electrical energy to light without the thermal byproducts of conventional lighting.

The patent introduces a heat sink as an intermediary component between the LED and the fiber optic cable. This heat sink actively manages and dissipates the relatively low heat generated by the LED, serving as a protective barrier that prevents any potential thermal damage to the cable while allowing the LED to operate at optimal temperatures for high-intensity light output.

The patent merges multiple optical functions into a single integrated collimating optic assembly. This component simultaneously performs light collimation, focusing, and transmission guidance, eliminating the need for separate optical elements. The unified design achieves high light transmission efficiency while minimizing the number of parts and overall device complexity.

The collimating optic assembly is designed as a multi-functional element that handles multiple optical tasks within a single component. It provides collimation to parallelize light rays, focuses light onto the fiber optic cable, and maintains proper beam geometry throughout transmission. This universal approach reduces system complexity compared to using dedicated separate components for each function.

The patent applies local quality by concentrating heat dissipation features specifically at the LED mounting location rather than distributing thermal management throughout the entire device. The heat sink is positioned directly at the heat source to provide localized cooling, allowing compact overall device dimensions while maintaining adequate thermal performance at the critical hot spot.

The patent changes the thermal management approach by using high-thermal-conductivity materials in the heat sink structure. This material parameter change enables efficient heat transfer from the LED to the heat sink fins within a compact volume. The optimized thermal conductivity allows effective heat dissipation without requiring large surface area or extended cooling structures, thus maintaining compact device size.
