Referring to fig. 1 and fig. 2, an embodiment of the present application provides a lamp 100. The lamp 100 includes a first light emitting unit 110, a driving assembly, and a driving member 130.
The driving member 130 is used for driving the transmission assembly to move. The driving component is used to drive the first light emitting unit 110 to move along the elliptical track.
Specifically, the first light emitting unit 110 may be an LED light source. The first light emitting unit 110 may be a single color LED light source. The first light emitting unit 110 may also include a plurality of LED beads with different colors, thereby forming a multi-color LED light source. The drive 130 may be a motor.
In the lamp 100, the driving member 130 drives the transmission assembly to move, so that the transmission assembly drives the first light emitting unit 110 to move along the elliptical track. Since the motion locus of the first light emitting unit 110 is an ellipse, ellipses with different major and minor semi-axes can be designed so as to construct lamps 100 with different sizes and shapes, and thus the internal space and the light emitting requirements of different vehicles can be matched.
Since the first light emitting unit 110 moves along the elliptical trajectory, the light emitting effect of the first light emitting unit 110 when passing through each point on the movement trajectory thereof is the same, and thus, the light emitting effect of uniform light emission is achieved along the movement trajectory of the first light emitting unit 110.
Because the first light-emitting unit 110 can move along a certain track, a water flowing effect can be constructed by using one first light-emitting unit 110, and the lamp is low in energy consumption and low in cost.
Since the first light emitting unit 110 can move along the elliptical trajectory, a variety of light emitting effects can be constructed by controlling the moving speed, time, and brightness of the first light emitting unit 110.
Referring to fig. 1 and fig. 2, in an embodiment, the lamp 100 further includes a first rail 141, a second rail 142, a first slider 143, and a second slider 144. The second guide rail 142 intersects the first guide rail 141. The extending direction of the second rail 142 is perpendicular to the extending direction of the first rail 141. The length of the second rail 142 is smaller than the length of the first rail 141. The first slider 143 reciprocally slides along the first guide rail 141. The second slider 144 reciprocally slides along the second guide rail 142.
Specifically, the first rail 141 has a first sliding slot, the first slider 143 is located in the first sliding slot, and the first slider 143 can slide back and forth along the first sliding slot. The second guide rail 142 has a second sliding slot, the second sliding block 144 is located in the second sliding slot, and the second sliding block 144 can slide along the second sliding slot in a reciprocating manner. Since the first guide rail 141 and the second guide rail 142 intersect and are perpendicular, so that the extending direction of the first sliding chute and the extending direction of the second sliding chute are perpendicular, the first sliding chute and the second sliding chute communicate at the intersection of the first guide rail 141 and the second guide rail 142.
The transmission assembly includes a first linkage member 121, a first rotating shaft 122, a second rotating shaft 123, a second linkage member 124, a third rotating shaft 125, and a driving rotating shaft 126.
The first rotating shaft 122 is pivotally connected to the first slider 143 and the first link 121, respectively, and since the movement of the first slider 143 is restricted by the first guide rail 141, the movement of the first link 121 is restricted by the first slider 143. The second rotating shaft 123 is pivotally connected to the second slider 144 and the first link member 121, respectively, and since the movement of the second slider 144 is limited by the second guide rail 142, the movement of the second link member 124 is limited by the second slider 144.
The third rotating shaft 125 is located between the first rotating shaft 122 and the second rotating shaft 123. The third rotating shaft 125 is pivotally connected to the first and second linkage members 121 and 124, respectively. The driving shaft 126 is driven by a driving member 130. In the present embodiment, the central axis of the second rail 132 is defined as an x-axis, and the central axis of the first rail 141 is defined as a y-axis. The center axis of the drive spindle 126 is located at the intersection of the center axis y-axis of the first rail 141 and the center axis x-axis of the second rail 142. The central axis of the driving shaft 126 is perpendicular to the central axis y of the first guide rail 141 and the central axis x of the second guide rail 142.
The first light emitting unit 110 is disposed on the first linkage member 121. In the present embodiment, the first light emitting unit 110 is located on a side of the first rotating shaft 122 away from the second rotating shaft 123.
Specifically, the driving shaft 126 may be fixed on a motor shaft of the motor, and the motor drives the driving shaft 126 to rotate. When the driving shaft 126 is driven by the driving member 130 to rotate, the driving shaft 126 drives the second linkage member 124 to rotate, and the second linkage member 124 drives the third shaft 125 to rotate synchronously. The rotation of the third shaft 125 drives the first linkage member 121 to rotate. The rotation of the first linkage member 121 drives the first sliding block 143 to slide in the first guide rail 141, and drives the second sliding block 144 to slide in the second guide rail 142, so that the movement track of the first linkage member 121 is limited by the movement of the first sliding block 143 and the movement of the second sliding block 144.
According to the geometric relationship of the first rail 141, the second rail 142, the first slider 143, and the second slider 144 and the transmission relationship of the transmission assembly, it can be known that when the first linkage member 121 rotates, the first light emitting unit 110 on the first linkage member 121 moves along an elliptical track.
Specifically, in the present embodiment, an xy coordinate system as in fig. 1 is established. The angle between the first linkage member 121 and the second guide rail 142 is θ, and the coordinates of the first light emitting unit 110 are (x ═ acos θ, y ═ bsin θ) according to the geometric relationship. The equation of motion of the first light-emitting unit 110 can be derived from the coordinates of the first light-emitting unit 110 as: x is the number of2/a2+y2/b21, the motion equation of the ellipse is satisfied.
In other embodiments, the first light emitting unit 110 may also be located on a side of the second rotating shaft 123 far away from the first rotating shaft 122. The same can also be said that the motion trajectory of the first light-emitting unit 110 is an ellipse.
Since the motion locus of the first light emitting unit 110 is an ellipse, the size of the first guide rail 141, the size of the second guide rail 142, the size of the first linkage member 121, the size of the second linkage member 124, and the position where the first light emitting unit 110 is arranged can be designed so as to design an ellipse with a long half shaft and a short half shaft according to requirements, and further, the size and the shape of the lamp 100 according to requirements can be designed according to the internal space and the lighting requirement of different vehicles.
Referring to fig. 2 in conjunction with fig. 1, in an embodiment, the lamp 100 further includes a housing 150 and a first buffer 160.

The first rail 141 is fixedly connected to the housing 150. The first buffer 160 is located between the first rail 141 and the housing 150.
Specifically, the first rail 141 and the housing 150 may be connected by a screw connection, a heat-staking connection, or a rivet connection. The first guide rail 141 is fixedly connected to the housing 150, so that the first guide rail 141 is convenient to mount, and the first cushion 160 can be sandwiched between the first guide rail 141 and the housing 150, so that the first cushion 160 is convenient to mount. The first dampener 160 may be a cushion. The first buffer 160 can reduce vibration and noise generated when the transmission assembly drives the first light emitting unit 110 to move.
Referring to fig. 2, in an embodiment, the housing 150 includes a lamp socket 151 and a face cover 152. The lamp holder 151 and the cover 152 enclose a receiving cavity. The lamp socket 151 forms a concavo-convex structure having a plurality of protrusions 1511 and depressions 1512 alternately arranged, so that the concavo-convex structure serves to reinforce the structural strength of the lamp socket 151.
In one embodiment, the mask 152 has a non-light-transmission region and a light-transmission region, and the light-transmission region of the mask 152 and the non-light-transmission region of the mask 152 are integrally formed by a two-color injection molding process, so that the processing is convenient.
Specifically, the non-light-transmitting regions of the lamp socket 151 and the cover 152 are connected so as not to affect the light-emitting effect. The lamp socket 151 and the face cover 152 may be coupled by a screw coupling, an adhesive bonding, a thermal fusion, or a laser welding, etc.
In an embodiment, the second linkage member 124 is provided with a second light emitting unit (not shown), so that the lamp 100 can have more complicated and diversified light emitting effects. It is understood that the second linkage member 124 rotates along a circular arc track, and therefore, the motion track of the second light emitting unit on the second linkage member 124 is not an elliptical track. In particular, the second light emitting unit may be an LED light source.
In one embodiment, a third light emitting unit (not shown) is further disposed on the first linkage member 121. The third light emitting unit is positioned between the first and second rotating shafts 122 and 123, so that it is possible to construct more complicated and diversified light emitting models. It is understood that the motion trajectory of the third light emitting unit is not an elliptical trajectory. Specifically, the third light emitting unit may be an LED light source.
In one embodiment, the luminaire 100 further includes an interior trim panel 170 fixedly connected to the housing 150 and located inside the housing 150. Interior trim panel 170 is positioned between face shield 152 and first track 141. The interior trim panel 170 has an annular hole 171, and the shape of the annular hole 171 corresponds to the movement locus of the first light emitting unit 110, so that the first light emitting unit 110 rotates along the annular hole 171 within the annular hole 171. The annular hole 171 of the interior panel 170 can expose the first light emitting unit 110, and the portion outside the annular hole 171 of the interior panel 170 can shield various components in the lamp 100, so that the lamp 100 has a better light emitting effect.
In one embodiment, the actuator 130 is fixedly connected to the trim panel 170, which facilitates installation of the actuator 130. In this embodiment, the driving member 130 is a motor. The luminaire 100 further comprises a second buffer 180. The second buffer member 180 is located at the periphery of the driving member 130 and is fixedly connected to the interior trim panel 170, so that the second buffer member 180 can reduce noise and vibration generated when the motor rotates. In particular, the second bumper 180 may be a cushion pad.
In an embodiment, the number of the first light emitting units 110 may be multiple, for example, three, five, six, etc. The plurality of first light emitting units 110 are disposed on the first linkage member 121, so that diverse lighting effects can be configured. The first light emitting units 110 may be distributed on the first linkage member 121 at equal intervals, or may be distributed unevenly, and the distribution manner may be designed according to the requirement of the light effect.
In one embodiment, the time for the first light emitting unit 110 to rotate once along the elliptical trajectory is less than 40 milliseconds, which is very short, so that the effect of continuously emitting light along the elliptical trajectory can be visually observed. Specifically, the time for the first light emitting unit 110 to rotate one turn along the elliptical trajectory may be 20 milliseconds, 30 milliseconds, 35 milliseconds, and the like.
