It should be emphasized that, for convenience of explaining the operation principle of the light-emitting structure, the vehicle lamp 10 is taken as an application scene for explanation, but the light-emitting structure of the embodiment is not limited to be applied to the vehicle lamp 10, and can be applied to lamps such as office lamps and household lamps.
The light-emitting structure of the above embodiment, when using in car light 10, transmission assembly 300 and swing piece 200 all set up in the installation cavity 1100 of the shell 1000 of car light 10, utilize transmission assembly 300 to be connected with the transmission of swing piece 200, thereby can drive swing piece 200 around corresponding swing axis in predetermineeing the reciprocal swing of swing frequency in the range of the swing angle with predetermineeing, thereby make luminous piece 100 around corresponding swing axis in predetermineeing the range of the swing angle with predetermineeing swing frequency reciprocating motion, and then can realize even area light source in predetermineeing the range of the swing angle, thereby make car light 10 can send even illuminating light, the security of driving at night has been guaranteed. Moreover, the light emitting element 100 can emit uniform illumination light only by using the transmission assembly 300 and the swinging element 200, and the cost is low.

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.

The swinging angle is as follows: refers to the angle at which a component swings from one extreme position to the other opposite extreme position during rotation about an axis of rotation. For example, in practical applications, the swinging member 200 can rotate from one extreme position to another extreme position around a rotation axis, and the angle of the swinging member 200 swinging around the rotation axis is the swinging angle. The oscillating member 200 drives the light emitting member 100 to oscillate reciprocally, preferably the oscillating member 200 oscillates in a fan shape to drive the light emitting member 100 to move in an arc reciprocating manner.
