Lamp with fin-type cooling module

The utility model provides a lamp with a fin-type cooling module, which is mainly formed by combination of at least one LED unit, a cooling module, a substrate, a transparent cover body, a ring-shapedjacket, a base and a circuit board. The cooling module is formed by the combination of a plurality of cooling fins which are coordinated with a head conducting plate as well as a fixed plate, and thecooling fins are connected in series in a shape of a radial interval ring; and the ring-shaped jacket is used for enclosing the outer ring at the top end of the cooling fins. The LED unit is combinedon the substrate, positioned in a concave step formed at the center of the cooling fins and combined on the heat conducting plate. At least one taper-shaped light-focusing body on the transparent cover body is utilized for focusing light sources projected by the LED unit and focuses and projects the light sources to the outside. Heat generated by the LED unit can be transferred to the heat conducting pate through the subst
