A beam angle adjustable LED lamp has a semicircular and tubular heat-dissipating body (10), a light source module (20) mounted on the heat-dissipating body (10) to constitute a thermal contact therewith, a contact module (30) pivotally mounted on one end of the heat-dissipating body (10), and a power converter (40) mounted inside the heat-dissipating body (10) and respectively and electrically connected with the light source module (20) and the contact module (30). With the foregoing structure, a lighting direction of the light source module (20) is perpendicular to an electrical connection path of the contact module (30) and a lamp socket. As the contact module (30) is pivotable relative to the heat-dissipating body (10) a beam angle of the light source module (20) on the heat-dissipating body (10) can be adequately adjusted based on a lighting requirement. |
