When the color temperature adjusting device is used, the circuit board (2) is arranged inside the base (1), the circuit board (2) is respectively and electrically connected with the color temperature sheet (36) and the electromagnet (39), the electromagnet (39) is respectively in limited connection with the left side and the right side of the bottom of the base (1), when the color temperature is adjusted, the magnetic field intensity of the electromagnet (39) is controlled through a dial switch circuit on the circuit board (2), the magnetic block (38) is attracted to pull the cam rod group (37), the cam rod group (37) is in transmission connection with one end, far away from the center of the base (1), of the grooved roll (31), the grooved roll (31) is symmetrically arranged around the center of the base plate mirror surface (35), the grooved roll (31) in bilateral symmetry rotates in the same direction, the limit block (32) in limited connection with the periphery of the grooved roll (31) is far away in the opposite direction, and the top of the limit block (32) is respectively and fixedly connected with the upper stop piece (34) and the lower stop piece (33), with the back-to-back distance of the limiting blocks (32), the distance between the upper blocking pieces (34) and the distance between the lower blocking pieces (33) are gradually increased, the distance between the upper blocking pieces (34) depends on the distance between the front side limiting blocks (32), the distance between the lower blocking pieces (33) depends on the distance between the rear side limiting blocks (32), and the distance between the front side limiting blocks and the rear side limiting blocks (32) is changed along with the change of the rotation angle of the front side grooved roll (31) and the rear side grooved roll (31);
After the color temperature adjustment is finished, when the condensation range needs to be adjusted, because the top edge of the base (1) is connected with an inner cover body (43) through a corrugated ring pipe (45), meanwhile, the periphery of the inner cover body (43) is movably connected with an outer cover body (44), at the moment, the outer cover body (44) is pushed upwards, under the limit of the outer cover body (44), the inner cover body (43) slides upwards along the outer wall of the lampshade (41) and gradually approaches, the corrugated ring pipe (45) at the bottom end of the inner cover body (43) synchronously extends to protect the bottom of the lampshade (41), and as the inner cover body (43) approaches upwards and the radius is synchronously reduced, the outer cover bodies (44) move upwards together and approach each other to reduce the caliber of the top part, the distance between the fixed blocks (46) fixedly connected with the middle part of the outer cover body (44) is reduced so that the elastic rod (47) is bent to store force, the internal mixed color light source is reflected by the reflective coating (42) and emitted from the aperture of the inner cover (43) and the outer cover (44) after being gathered together.
