In a lamp heat dissipating device and a heat dissipating assembly mounted onto a lamp base, the heat dissipating device includes a heat conducting base, a U-shaped heat pipe, and a heat dissipating body. The heat conducting base includes a groove formed on a surface of the heat conducting base. The U-shaped heat pipe includes an evaporation section and two condensation sections, and the evaporation section is combined into a groove. The heat dissipating body includes a circular cylinder and a plurality of hollow heat dissipating cylinders. The circular cylinder includes two containing grooves provided for inserting two condensation sections respectively, and the heat dissipating cylinders are arranged into a circular shape with a gap from one another and installed on an external side of the circular cylinder to increase the heat conducting area and heat dissipating area so as to improve the heat dissipating efficiency. |
