The invention discloses a high-power LED lamp based on a heat pipe for thermal conductivity and relates to an LED lamp. The prior high-power LED lamp has unsatisfactory heat transference and poor heat dissipation effect. The high-power LED lamp comprises an LED chip, a chip base, a heat dissipation device which is connected with the chip base and a light distribution device which is arranged on the chip base. The high-power LED lamp is characterized in that the heat dissipation device comprises a heat radiator and a plurality of heat pipes which connect the heat radiator with the chip base; and a plurality of inner grooves which are matched with the heat pipes are correspondingly formed on the chip base for containing the heat pipes, and a metal welding layer is arranged between the inner grooves and the heat pipes for connecting the chip base which is covered by the chip with the heat radiation device so as to form an integrated light source. The technical method has good heat conduction effect, rapid heat dissipation and reliable connection.
