Description

A lighting device Technical Field

[0001] The invention relates to a lighting device. Background Art

[0002] Although track lights can move on the track bar through a motion mechanism, thereby changing the illumination position, the light beam emitted from the track light does not change its emission angle relative to its light-emitting surface. That is, for users, the luminous effect of the track light itself does not change.

[0003] Chinese patent CN215174364U discloses a lamp that simulates natural sunlight. The patent discloses a technical solution that changes the angle of a reflector by rotating a component, thereby changing the angle of the light beam emitted from the lamp relative to the light-emitting surface of the lamp to simulate the change in the projection angle of sunlight. However, in this solution, the reflector rotates back and forth about a horizontal axis, so that the light beam emitted to the ground only moves back and forth in a straight line. The movement is monotonous, the simulation effect is average, and the lamp lacks market competitiveness. Therefore, the applicant has developed a new structural design to enable the light beam emitted from the lamp to better change its emission direction relative to its light-emitting surface and change the beam illumination area.
