The oscillating member 200 may be configured as a swing rod, a swing arm, or other elements capable of driving the light emitting member 100 to swing back and forth around the swing axis within a predetermined swing angle range at a predetermined swing frequency. The light emitting member 100 can be fixed to one end of the swinging member 200 by clipping, bonding or inserting. In order to ensure that the light emitting member 100 can form a surface light source when swinging within the preset swing angle range, the swing frequency of the light emitting member 100 needs to meet the requirement that human eyes cannot sense flicker, and preferably, the swing frequency of the swinging member 200 is at least 100HZ, wherein the swing frequency refers to the number of times that the swinging member 200 swings back and forth in unit time.
