A therapeutic lamp (1) for biostimulation with polarized light, which comprises a light source with a power substantially between 30W and 300W, a reflector (5) with a rotational paraboloid light reflecting surface arranged behind the light source so that the focal point substantially coincides with the point source, a polarizer (4) arranged in the path to generate polarized output light which has a cross-section of at least 100 cm<2>. The lamp further comprises a first tube (3) with a first axis coinciding with axis of rotation of the paraboloid surface, the reflector (5) with the light source is fixed in the first tube (3) so that a sealed connection is provided therebetween, a second tube (2) with a second axis which closes an angle between 110 DEG and 120 DEG with the first axis, the tubes have substantially equal and circular cross-sections and are attached to each other to form an integral housing, both of the tubes are cut with a plane extending normal to a plane determined by the first and second axes, the cutting plane closes substantially the same angle with the first and second axis, whereby an opening with an elliptical contour line is defined, a light diverting means (4) preferably the polarizer closes the opening for the diverting light arriving from the first tube (3) to axial direction of the second tube (2), the means (4) comprises a closing plate (24) of a heat conducting material and has a heat dissipating increased rear surface (25), a light transparent plate (7) is arranged in frontal section of the second tube to close and seal the inner space thereof, and static heat dissipating means which contacts the reflector (5) for providing operational temperature for the light source. |
