Abstract

This invention relates to an integrated endoscopic light source device that is lightweight, compact, easily detachable, and can be used as a standalone endoscopic light source unit. It includes a fiber optic interface, a light-emitting component, and an electronic control board. The fiber optic interface is housed within a rectangular heat sink, which forms a central channel within the heat sink. The light-emitting component is located at the rear end of the central channel, and a cooling fan is positioned at the rear end of the light-emitting component. Integrating the fiber optic interface, heat sink, electronic control board, cooling fan, and electronic control board into a single, portable endoscopic light source unit is achieved. The heat sink serves as a quick-access interface for the fiber optic cable and also contributes to a smaller device size. Therefore, it offers advantages such as small size, light weight, portability, ease of maintenance, and low manufacturing cost.
