An LED lamp having a heat dissipation function comprises a heat dissipation body (11), a mean temperature steam chamber (21), a circuit module (31), and at least one LED unit (41). The heat dissipation body (11) is a solid metal which forms an upper surface (12) and a lower surface (16) on a top portion and a bottom portion of the heat dissipation body (11) respectively. The upper surface (12) has a top point (121), and the upper surface (12) tilts to the surroundings and extends downward from the top point (121). Multiple bumps (13) are formed on the upper surface (121), and the bumps (13) are distributed in the form of particles on the upper surface (12). Multiple flowing passages (14) are formed between the bumps (13), and the flowing passages (14) are arranged from the top down and extend toward the edge of the heat dissipation body (11). A depressed portion (161) is formed from the bottom up on the lower surface (16), and the depressed portion (161) has a flat bottom surface. The heat dissipation body (11) extends downward and outward along the bottom surface of the depressed portion (161) to form an eave portion (17), and forms, between the depressed portion (161) and the eave portion (17), an inner tilt surface (171) extending upward and inward from the bottom edge of the eave portion (17). A top surface of the mean temperature steam chamber (21) is attached to the bottom surface of the depressed portion (161). A top surface of the circuit module (31) is attached to a bottom surface of the mean temperature steam chamber (21). At least one LED unit (41) is disposed on a bottom surface of the circuit module (31). |
