This utility model relates to the field of lighting technology, specifically to a high-efficiency heat dissipation ultra-high brightness linear
light source. It includes a support frame, a
heat sink slidably mounted on the top of the support frame, a light-transmitting plate mounted on the top of the side plate, heat dissipation fins mounted on the bottom of the
heat sink, a fan body mounted inside the mounting frame, a substrate mounted on the top of the
heat sink, a
light guide rod mounted on the top of the substrate, a reflector mounted on the top of the substrate, a limiting mechanism mounted inside the reflector, and an adjustment mechanism mounted on the top of the heat sink. This utility model, through the arrangement of components such as the heat sink, heat dissipation fins, fan body, limiting mechanism, and adjustment mechanism, and the cooperation between the fan body, the heat sink, and the heat dissipation fins, allows the fan body to dissipate heat generated during equipment operation, thereby cooling the equipment. Furthermore, the limiting mechanism and the adjustment mechanism, combined with the adjustment mechanism, allow adjustment of the
light spot by adjusting the position of the
light guide rod, achieving the effect of adjusting the light focusing area.
