Referring to fig. 1 and 2, a light emitting device 10 of the present application includes a light emitting element 11, a first light guiding element 13, a second light guiding element 15 and a switch element 17. The light emitting member 11 is for emitting light. The first light guide member 13 is opposite to the light emitting side 111 of the light emitting member 11, and the first light guide member 13 is configured to guide light emitted by the light emitting member 11. The second light guide 15 includes a first side 151, a second side 152 and a third side 153, the first side 151 of the second light guide 15 is opposite to the first light guide 13, and the light guided out by the first light guide 13 is incident through the first side 151 of the second light guide 15, reflected by the second side 152 of the second light guide 15, and then exits from the third side 153 of the second light guide 15. The switch member 17 is disposed between the first light guide member 13 and the second light guide member 15, and the switch member 17 is configured to block or open a light transmission path between the first light guide member 13 and the second light guide member 15.

In the light emitting device 10 of the present application, the switching member 17 can be used to control the intensity of the light emitted from the first light guide member 13 to the second light guide member 15. In the case where the switching member 17 blocks the light transmission path between the first light guide member 13 and the second light guide member 15, the side surface 135 of the second light guide member 15 does not emit light, and in the case where the switching member 17 is gradually turned from the blocked state to the open state, the luminous flux of the light passing through the switching member 17 and entering the second light guide member 15 gradually increases, and the side edge of the second light guide member 15 can be gradually lighted to form the running water lighting effect of the vehicle lamp. On the one hand, the lighting effect of the lighting device 10 is better, and on the other hand, the scheme that the single light guide member realizes the gradual lighting effect can reduce the space occupied by the lighting device 10.

The light emitting device 10 is further described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, in some embodiments, the light emitting element 11 is an electrical component capable of emitting light to the first light guiding element 13. The type of the light emitting member 11 includes, but is not limited to, a point light source, a ring light source, a parallel light source, or the like. The light emitted by the light emitting element 11 at least includes visible light, and when the light passes through the first light guiding element 13, the first light guiding element 13 can transmit and reflect the light, so that the first light guiding element 13 can emit light that can be recognized by human eyes, and the reflected light is transmitted to the second light guiding element 15. In some embodiments, the light emitting element 11 has a power supply built in, and the power supply can supply power to the light emitting element 11 to make the light emitting element 11 emit light. In other embodiments, the light emitting element 11 is electrically connected to a power supply device in the vehicle 1000, and the power supply device in the vehicle 1000 directly supplies power to the light emitting element 11 to cause the light emitting element 11 to emit light.

Specifically, in some embodiments, the lighting element 11 includes a circuit board and a lamp bead. The lamp beads can emit light toward the side surface 135 of the first light guide 13 to make the light emitting part of the first light guide 13 emit light. The circuit board is provided with various electronic components, including but not limited to wires, switches, capacitors, inductors, resistors, etc. The lamp bead can be mounted on one side of the circuit board facing the first light guide member 13 and electrically connected with the circuit board, so that the lamp bead is opposite to the first light guide member 13. At this time, the light emitted by the lamp beads can enter the first light guide member 13, and the light emitting side 111 of the light emitting member 11 is the side of the circuit board, on which the lamp beads are mounted and which is close to the first light guide member 13.

More specifically, in some embodiments, the light emitting member 11 includes one light emitting member 11 disposed on either side of the first light guiding member 13, and the light emitted from the light emitting member 11 enters the first light guiding member 13 and can be reflected multiple times in the first light guiding member 13 and the first light guiding member 13 can emit light in the direction of the second light guiding member 15. In other embodiments, the light emitting member 11 includes a plurality of light emitting members 11, and each of the plurality of light emitting members 11 is capable of emitting light toward the first light guide member 13. In one example, the plurality of light emitting members 11 are disposed on different sides of the first light guiding member 13. In another example, at least two light emitting members 11 are disposed on the same side of the first light guiding member 13. Compared with the scheme that only one light emitting piece 11 exists, the plurality of light emitting pieces 11 are arranged, so that more light enters the first light guiding piece 13, more light is transmitted from the first light guiding piece 13 to the second light guiding piece 15, the light emitting brightness of the second light guiding piece 15 is higher, and the formed pattern can be clearer.

Referring to fig. 2 and 3, in some embodiments, the first light guide 13 is a structure that is capable of transmitting and guiding light, and is capable of reflecting light to change the light transmission direction. The first light guide 13 has a substantially columnar structure, and the outer contour shape of the cross section of the first light guide 13 includes, but is not limited to, a right circular shape, an elliptical shape, a triangular shape, a quadrangular shape, a pentagonal shape, or the like. The first light guide 13 is made of a transparent material with good light guiding performance, and the material of the first light guide 13 includes, but is not limited to, plastic, resin, glass, or the like. In some embodiments, the light emitting member 11 is mounted on the first light guiding member 13, and the connection manner between the light emitting member 11 and the first light guiding member 13 may be a detachable connection manner such as a snap connection, a screw connection, or a bolt connection, or may be a non-detachable connection manner such as a glue connection or a hot melt connection, which is not limited herein. In other embodiments, the light emitting member 11 and the first light guiding member 13 are separated from each other, and the light emitting side 111 of the light emitting member 11 faces the first light guiding member 13 and corresponds to at least one surface of the first light guiding member 13, so that light enters into the first light guiding member 13 as much as possible.

Specifically, in some embodiments, the first light guide 13 includes a first surface 131 and a second surface 133 that are opposite to each other, and a side surface 135 that connects the first surface 131 and the second surface 133, respectively. In the case that the first light guide 13 has a columnar structure, the first surface 131 of the first light guide 13 and the second surface 133 of the first light guide 13 are a top surface and a bottom surface of the columnar structure, respectively, and the side surface 135 of the first light guide 13 is an annular side surface 135 having a certain height in the columnar structure. In some embodiments, the light emitting side 111 of the light emitting element 11 faces the first surface 131 of the first light guiding element 13 and/or the second surface 133 of the first light guiding element 13, and the light emitted by the light emitting element 11 is emitted from the first surface 131 of the light guiding element and/or the second surface 133 of the first light guiding element 13 into the first light guiding element 13, and is emitted from the side 135 of the first light guiding element 13 after multiple reflections. In other embodiments, the light emitting side 111 of the light emitting element 11 faces the side 135 of the first light guiding element 13, and the light emitted by the light emitting element 11 enters the first light guiding element 13 from the side 135 of the light guiding element and is reflected multiple times and then exits from the first surface 131 of the first light guiding element 13, the second surface 133 of the first light guiding element 13, and/or the side 135 of the first light guiding element 13.

More specifically, in some embodiments, the first light guide 13 is provided with a refractive structure inside, and the refractive structure may be a plurality of total reflection surfaces or may be a lattice point capable of reflecting light multiple times. Taking the refraction structure as a plurality of total reflection surfaces as an example, when the light emitted by the light emitting element 11 enters the first light guiding element 13 through the first surface 131 of the first light guiding element 13 and/or the second surface 133 of the first light guiding element 13, the light can irradiate on one of the total reflection surfaces and be reflected to the side surface 135 of the first light guiding element 13 (towards the inner side of the first light guiding element 13) in the first light guiding element 13, and the light can be directly transmitted out of the first light guiding element 13 at the side surface 135 of the inner side of the first light guiding element 13, so that the light transmitted by the first light guiding element 13 is emitted from the side surface 135 of the first light guiding element 13. The side surface 135 of the light ray inside the first light guide 13 can further reflect to another total reflection surface through the side surface 135 of the first light guide 13 (toward the inside of the first light guide 13), so that the light ray is continuously conducted inside the first light guide 13.

Referring to fig. 2 and 4, in some embodiments, the second light guide 15 is configured to transmit light and emit light at the side 135. The first light guide 13 is made of a transparent material with good light guiding performance, and the material of the first light guide 13 includes, but is not limited to, plastic, resin, glass, or the like.

Specifically, in some embodiments, the second light guide 15 has a substantially plate-shaped structure, and the light emitted from the first light guide 13 can enter the second light guide 15 through the first side 151 of the second light guide 15 and be reflected at the second side 152 of the second light guide 15 located inside the second light guide 15, and the reflected light can continue to be conducted inside the second light guide 15 and be emitted through the third side 153 of the second light guide 15. The third side 153 of the second light guide 15 is in contact with both the first side 151 of the second light guide 15 and the second side 152 of the second light guide 15.

More specifically, in certain embodiments, the second light guide 15 further includes a fourth side 154, a fifth side 155, and a sixth side 156. In some embodiments, as shown in fig. 4, the first side 151 of the second light guide 15 is contiguous with the second side 152 of the second light guide 15, the first side 151 of the second light guide 15 is opposite the fourth side 154 of the second light guide 15, the second side 152 of the second light guide 15 is opposite the fifth side 155 of the second light guide 15, and the third side 153 of the second light guide 15 is opposite the sixth side 156 of the second light guide 15. At this time, adjacent two sides of the third side 153 of the second light guide 15 are respectively connected to the first side 151 of the second light guide 15 and the second side 152 of the second light guide 15. In other embodiments, as shown in fig. 5, the first side 151 of the second light guide 15 is opposite the second side 152 of the second light guide 15, the third side 153 of the second light guide 15 is opposite the fourth side 154 of the second light guide 15, and the fifth side 155 of the second light guide 15 is opposite the sixth side 156 of the second light guide 15. At this time, opposite sides of the third side 153 of the second light guide 15 are respectively connected to the first side 151 of the second light guide 15 and the second side 152 of the second light guide 15. The light emitted from the first light guide 13 can be transmitted into the second light guide 15 through the first side 151 of the second light guide 15, and since the plane of the second side 152 of the second light guide 15 in the second light guide 15 is a total reflection surface, the light entering into the second light guide 15 is totally reflected at the second side 152 (toward the inner side of the second light guide 15) of the second light guide 15, and the light after total reflection is transmitted from the second light guide 15 and emitted from the third side 153 of the second light guide 15, and at this time, the human eye can see the light reflected by the second side 152 of the second light guide 15, which is represented by the light emitted by the second side 152 of the second light guide 15.

More specifically, in some embodiments, when the first side 151 of the second light guide 15 is in contact with the second side 152 of the second light guide 15, the second side 152 of the second light guide 15 is inclined, and the second side 152 of the second light guide 15 is disposed obliquely with respect to the third side 153 of the second light guide 15 and the sixth side 156 of the second light guide 15. In the case that the second side 152 of the second light guide 15 is inclined, the second side 152 of the second light guide 15 emits light in a direction offset by a certain angle with respect to the incident light after receiving the light, rather than reflecting in the direction of the incident light, so that the light can be emitted from the third side 153 of the second light guide 15.

Further, in some embodiments, the second side 152 of the second light guiding member 15 is provided with a refractive region 105, and the refractive region 105 is a refractive texture, such as a concave-convex texture or a leather texture, disposed on the second side 152 of the second light guiding member 15, and in the case that the light is transmitted to the second side 152 of the second light guiding member 15, the refractive region 105 can be used to reflect the light emitted from the first side 151 of the second light guiding member 15 to the third side 153 of the second light guiding member 15 multiple times on the surface of the second side 152 of the second light guiding member 15. The provision of the refractive region 105 can increase the number of times light is reflected at the second side 152 of the second light guide 15 and increase the luminous flux of light reflected from the second side 152 of the second light guide 15 to the third side 153 of the second light guide 15 and transmitted from the third side 153 of the second light guide 15, as compared with the case where the refractive region 105 is not provided, so that the brightness of side light emission of the second light guide 15 is increased.

Referring to fig. 2 and 7, the switch 17 is configured to control the light transmission path between the first light guide 13 and the second light guide 15 to be cut off or turned on. The switch member 17 is disposed between the first light guide member 13 and the second light guide member 15, and the switch member 17 completely blocks light transmitted from the first light guide member 13 to the second light guide member 15 when the switch member 17 is in the off state. When the switch member 17 is in the on state, the switch member 17 can pass light, and at this time, the light emitted from the first light guide member 13 can enter the second light guide member 15.

Specifically, in some embodiments, along the direction in which the first light guide 13 points toward the switch member 17, the projection of the first light guide 13 is located within the switch member 17, so that the switch member 17 can completely cover the first light guide 13 and completely block the light emitted from the first light guide 13 toward the second light guide 15 when the switch member 17 is in the off state.

More specifically, in some embodiments, as shown in fig. 7 and 8, the switch member 17 is a liquid crystal member, and in the absence of an electric field, the liquid crystal molecules in the liquid crystal member are disordered, and at this time, the light is repeatedly reflected and refracted in the liquid crystal member and cannot pass through the liquid crystal member, so that the liquid crystal member can block the light transmission path between the first light guide member 13 and the second light guide member 15, and the light cannot be transmitted to the second light guide member 15 through the liquid crystal member, and the second side 152 of the second light guide member 15 does not emit light. Under the action of an electric field, the liquid crystal molecules in the liquid crystal member are arranged in a fixed order, and at this time, the light can pass through the gaps between the liquid crystal molecules and pass through the liquid crystal member, so that the liquid crystal member can open a light transmission path between the first light guide member 13 and the second light guide member 15, so that the light is transmitted to the second light guide member 15 through the liquid crystal member, and the second side 152 of the second light guide member 15 can emit light.

In other embodiments, as shown in fig. 9, the switch member 17 is a light shielding member, which is a substantially opaque structure, and the material of the light shielding member includes, but is not limited to, metal, plastic, resin, or the like. In one example, the shade can be moved relative to the first light guide 13. In the direction in which the first light guide 13 is directed toward the switch member 17, the light guide is capable of blocking light emitted from the first light guide 13 when the projection of the light guide completely covers the first light guide 13, and the second light guide 15 does not emit light. In the case where the projection of the light shielding member moved to the light shielding member does not completely cover the first light guiding member 13, the light shielding member can shield only a part of the light emitted from the first light guiding member 13, and at this time, only a part of the second side 152 of the second light guiding member 15 emits light. When the light shielding member continues to move until the projection of the light shielding member is completely separated from the first light guiding member 13, the light shielding member cannot shield the light emitted from the first light guiding member 13, and at this time, the second side 152 of the second light guiding member 15 emits light entirely. Therefore, the flowing water light emitting effect of the light emitting device 10 can be achieved by adjusting how much the shade shields light. In another example, the light shielding member can rotate relative to the first light guiding member 13, and during the rotation of the light shielding member, the light shielding member gradually shields the light transmission path between the first light guiding member 13 and the second light guiding member 15. When the light shielding member is rotated to completely shield the light emitted from the first light guide member 13, the second light guide member 15 does not emit light. The second side 152 of the second light guide 15 emits light partially when the light shielding member is rotated to partially shield the light emitted from the first light guide 13. When the light-shielding member does not block the light emitted from the first light-guiding member 13, the second side 152 of the second light-guiding member 15 emits light entirely.

Referring to fig. 1 and 2, in some embodiments, the light emitting device 10 further includes a bracket 19, and the switch 17 is mounted on the bracket 19 and forms a receiving cavity 109 together with the bracket 19. The light emitting element 11 and/or the first light guiding element 13 are/is arranged in the accommodating cavity 109. The support 19 can isolate the light emitting element 11 and the first light guiding element 13 from the outside, so as to avoid direct contact of moisture, dust and the like with the light emitting element 11 and the first light guiding element 13, thereby influencing normal use of the light emitting device 10. The material of the support 19 includes, but is not limited to, metal, plastic, resin, or the like.

Specifically, in some embodiments, the support 19 includes a light-transmitting region 191 and a light-non-transmitting region 193, the light-transmitting region 191 being opposite to the switching element 17, and the light-transmitting region 191 being capable of transmitting and emitting light emitted through the side 135 of the first light guide 13 to the switching element 17. In some embodiments, the light-transmitting region 191 is an opening that communicates with the accommodating cavity 109 and is opposite to the side surface 135 of the first light guide 13, and when the first light guide 13 emits light, the light emitted from the side surface 135 of the first light guide 13 can be directed to the switch member 17 through the opening. In other embodiments, the light-transmitting region 191 is made of a light-transmitting material, and when the first light guide member 13 emits light, the light emitted from the side 135 of the first light guide member 13 can be directed to the switch member 17 through the light-transmitting region 191. The material of the light-transmitting region 191 includes, but is not limited to, light-transmitting plastic, light-transmitting resin, glass, or the like.
