An LED lamp with cooling structure includes a lamp tube, a LED module accommodated in the lamp tube and a cooling structure covering the outside of the lamp tube. The lamp tube has top plate and sidewall bended and extended from periphery of the top plate. The LED module includes circuit board attached onto inside face of the top plate and plural LEDs electrically connected onto the circuit board. The cooling structure has cover plate attached to outside face of the top plate and plural cooling fins bended and extended from periphery of the cover plate and interspaced to each other, in which the cooling fins cover the outside of the sidewall of the lamp tube and is formed a cooling channel with the sidewall. Thereby, an excellent efficiency of cooling is achieved and the manufacturing cost of the LED lamp is thus reduced.
