Abstract: A device for changing lamp color temperature includes a lamp holder installed therein with a luminous source. A colored lens is set in front of the luminous source and a rotary mechanism is connected with the colored lens. The rotary mechanism functions to drive the colored lens to rotate to a first position where the colored lens is far away from the luminous source and to a second position where the colored lens obstructs the front side of the luminous source. By so designing, a user can adjust the position of the colored lens and choose either to let the light emitted by the luminous source project directly or to let the light first pass through the colored lens to change color temperature and then project, thus able to adjust lamp color temperature in accordance with various environments.

Abstract: A lamp color temperature change structure includes a lamp holder, a light source on the lamp holder, a lift unit in front of the light source, and a colored lens mounted to the lift unit. The colored lens is movable and driven by the lift unit to a first position which is away from the front of the light source or a second position which is in front of the light source. The user can select the light from the light source to radiate toward the front of the lamp holder or penetrate the colored lens to generate a color temperature change and then radiate toward the front of the lamp holder according to different environment conditions.
