The vehicle lamp 100 of the above embodiment needs to adjust the brightness of the vehicle lamp 100, for example, when the vehicle lamp 100 is turned on, the light emitting body 110 is powered on and is turned on, at this time, the first light shielding member 121 and the second light shielding member 122 can both move towards the direction away from the light emitting body 110, so that the distance between the first light shielding member 121 and the second light shielding member 122 gradually increases, and further the area of the light transmission area 123 gradually increases, so that the light emitted by the light emitting body 110 continuously increases, and further the brightness of the vehicle lamp 100 gradually increases, thereby improving the visual effect when the vehicle lamp 100 is turned on. When the brightness of the car lamp 100 needs to be reduced or the car lamp 100 is turned off, at this time, the first light shielding member 121 and the second light shielding member 122 can both move towards the direction close to the light emitting body 110, so that the distance between the first light shielding member 121 and the second light shielding member 122 gradually decreases, and further the area of the light transmitting area 123 gradually decreases, so that the light emitted by the light emitting body 110 continuously decreases, and further the brightness of the car lamp 100 gradually decreases, until the first light shielding member 121 and the second light shielding member 122 are completely closed or the distance between the first light shielding member 121 and the second light shielding member 122 is within a preset range, so that the light shielding area formed by matching the first light shielding member 121 and the second light shielding member 122 can shield the light emitting body 110. The vehicle lamp 100 of the above embodiment can flexibly adjust the brightness of the vehicle lamp 100 by using the movement of the first light shielding member 121 and the second light shielding member 122 relative to the light emitting body 110, so that the light emitting body 110 is not impacted, and the service life of the light emitting body 110 is prolonged.
The light shielding member 120 is disposed in front of the light emitter 110, and means that the light shielding member 120 is disposed in front of the light emitter 110 along the light emitting direction of the vehicle lamp 100 (as shown in the direction C in fig. 2). The distance between the first light-shielding member 121 and the second light-shielding member 122 is within a predetermined range, which means that a certain predetermined gap may be left between the first light-shielding member 121 and the second light-shielding member 122 without contact, and the size of the predetermined gap may be flexibly adjusted according to actual use requirements. The light emitting body 110 may be other light emitting lamps such as a xenon lamp and a halogen lamp.
As shown in fig. 1 and fig. 2, in an embodiment, the vehicular lamp 100 further includes a light-transmitting cover 130, the light-transmitting cover 130 is provided with a mounting cavity 131, and the light emitter 110, the first light-shielding member 121 and the second light-shielding member 122 are all disposed in the mounting cavity 131. Therefore, the light emitting body 110, the first light shielding piece 121 and the second light shielding piece 122 are all arranged in the installation cavity 131 of the light transmitting cover 130, the light emitting body 110, the first light shielding piece 121 and the second light shielding piece 122 can be protected by the light transmitting cover 130, and the interference of external foreign matters (dust, rainwater and the like) on the normal work of the light emitting body 110, the first light shielding piece 121 and the second light shielding piece 122 can be avoided, so that the service life is ensured. The transparent cover 130 may be made of transparent material such as polymethyl methacrylate, polystyrene, and polycarbonate.
The first light-shielding member 121 and the second light-shielding member 122 may be in the form of light-shielding sheets or light-shielding plates, and only need to be able to shield the light emitted by the light-emitting body 110. The light shielding effect of the first light shielding member 121 and the second light shielding member 122 can be achieved by using opaque materials (e.g., metal materials such as opaque aluminum foil) for the first light shielding member 121 and the second light shielding member 122; the first light-shielding member 121 and the second light-shielding member 122 can be made of a light-transmitting material and then painted with corresponding black paint, and the light emitted by the light-emitting body 110 can be shielded by the first light-shielding member 121 and the second light-shielding member 122. The first light shielding member 121 and the second light shielding member 122 can move relative to the light emitting body 110 in a magnetic manner, and can move in a telescopic manner (for example, the telescopic rod is driven by a motor to stretch and move), so that the first light shielding member 121 and the second light shielding member 122 can be close to or far away from the light emitting body 110 at different moments.
As shown in fig. 1 and 2, in an embodiment, the first light shielding member 121 is configured as a first light shielding magnetic piece 1211, the second light shielding member 122 is configured as a second light shielding magnetic piece 1221, the first light shielding magnetic piece 1211 and the second light shielding magnetic piece 1221 can cooperate to form a light shielding region, and the first light shielding magnetic piece 1211 and the second light shielding magnetic piece 1221 can magnetically cooperate with the light emitting body 110 to enable the first light shielding magnetic piece 1211 and the second light shielding magnetic piece 1221 to reciprocate in a direction close to or away from the light emitting body 110 and are spaced apart from each other to form a light transmitting region 123. Thus, when the light emitting device 110 is powered on, a corresponding magnetic field is generated to repel the first light-shielding magnetic sheet 1211 along a first predetermined direction (as shown in the direction a of fig. 1 and 2) relative to the light emitting device 110 under the action of the magnetic force, under the action of the magnetic force, the second magnetism shielding sheet 1221 is repelled from the light emitting body 110 along a second predetermined direction (as shown in the direction B in fig. 1 and 2), so that the first and second magnetic shield pieces 1211 and 1221 are moved away from the light emitter 110, so that the distance between the first and second shade magnetic pieces 1211 and 1221 is gradually increased, thereby gradually increasing the area of the light-transmitting region 123, and increasing the light emitted by the light-emitting body 110, further, the brightness of the vehicle lamp 100 can be gradually improved, so that the vehicle lamp 100 presents a slowly brightening effect, and the visual effect of the vehicle lamp 100 is improved; when the light emitting body 110 is powered off, the magnetic field disappears, under the action of gravity, the first light-shielding magnetic sheet 1211 is close to the light emitting body 110 along the first preset direction, and under the action of gravity, the second light-shielding magnetic sheet 1221 is close to the light emitting body 110 along the second preset direction, so that the distance between the first light-shielding member 121 and the second light-shielding member 122 gradually decreases, and further, the area of the light-transmitting area 123 gradually decreases, so that the light emitted by the light emitting body 110 continuously decreases, and further, the brightness of the vehicle lamp 100 gradually decreases until the first light-shielding member 121 and the second light-shielding member 122 completely close together or the distance between the first light-shielding member 121 and the second light-shielding member 122 is within a preset range, so that the light-shielding area formed by the first light-shielding member 121 and the second light-shielding member 122 can shield the light emitting body 110, and the light cannot be emitted or less light is emitted when the light emitting body 110 is powered on, only when the first light shielding member 121 and the second light shielding member 122 move towards the direction away from the light emitting body 110, light can be transmitted out, and the effect of slowly opening the vehicle lamp 100 is ensured.
As shown in fig. 1 and 2, the vehicle lamp 100 further includes a first guide 141 and a second guide 142, the first guide 141 and the first shade magnetic piece 1211 are disposed on one side of the light body 110, one end of the first guide 141 is connected to the transparent cover 130, the first guide 141 is in guiding engagement with the first shade magnetic piece 1211, the second guide 142 and the second shade magnetic piece 1221 are disposed on the other side of the light body 110, one end of the second guide 142 is connected to the transparent cover 130, and the second guide 142 is in guiding engagement with the second shade magnetic piece 1221; along the emitting direction of the light emitting body 110, the first guiding member 141 is disposed obliquely to the emitting direction, and the second guiding member 142 is disposed obliquely to the emitting direction. Thus, when the light emitter 110 is powered on, the first magnetic shading sheet 1211 is repelled from the light emitter 110 along a first predetermined direction (as shown in a direction of fig. 1 and 2 a) by the magnetic force and the guiding action of the first guiding member 141, and the second magnetic shading sheet 1221 is repelled from the light emitter 110 along a second predetermined direction (as shown in B direction of fig. 1 and 2) by the magnetic force and the guiding action of the second guiding member 142. When the light emitting device 110 is powered off, the magnetic field disappears, so that the first magnetic shading sheet 1211 is close to the light emitting device 110 along the first predetermined direction under the action of gravity and the guiding action of the first guiding member 141, and the second magnetic shading sheet 1221 is close to the light emitting device 110 along the second predetermined direction under the action of gravity and the guiding action of the second guiding member 142. The movement locus of the first light-shielding magnetic sheet 1211 is more accurate by the first guide member 141, the movement locus of the second light-shielding magnetic sheet 1221 is more accurate by the second guide member 142, and in the moving process, the distance between the first light-shielding magnetic sheet 1211 and the second light-shielding magnetic sheet 1221 is continuously increased or decreased, so that the region where the light-transmitting region 123 is located is in a horn shape, thereby the profile of the emergent light is in a horn shape, the visual effect is better, and the brightness of the vehicle lamp 100 is enhanced along with the increase of the moving distance between the first light-shielding magnetic sheet 1211 and the second light-shielding magnetic sheet 1221. The first guide 141 and the second guide 142 are disposed to be inclined with respect to the emission direction, and preferably, are disposed at an acute angle (an angle of 30 °, 45 °, or 60 °, etc.). The guide engagement of the first guide member 141 with the first light-shielding magnetic piece 1211 and the guide engagement of the second guide member 142 with the second light-shielding magnetic piece 1221 may be achieved in a telescopic manner or in a sliding manner.
The guide of the first guide member 141 to the first light-shielding magnetic piece 1211 and the guide of the second guide member 142 to the second light-shielding magnetic piece 1221 may be achieved by a telescopic fit or an elastic contraction, and it is only necessary to satisfy the requirement that the first light-shielding magnetic piece 1211 and the second light-shielding magnetic piece 1221 move in the first and second predetermined directions. The first preset direction and the second preset direction may be straight lines or arcs, and only the first shading magnetic sheet 1211 needs to move in the first preset direction and the second shading magnetic sheet 1221 needs to move in the second preset direction, so that the first shading magnetic sheet 1211 and the second shading magnetic sheet 1221 can be close to or away from each other, and the area of the light-transmitting area 123 is increased or decreased.
In one embodiment, the first guide 141 is provided as a first telescopic rod; the second guide 142 is configured as a second telescoping rod. Thus, when the first light-shielding magnetic sheet 1211 is away from the light emitter 110 under the action of the magnetic force, the first telescopic rod is retracted, so that the movement of the first light-shielding magnetic sheet 1211 can be guided without affecting the transmission of the light. Similarly, when the second light-shielding magnetic sheet 1221 is away from the light-emitting body 110 under the action of magnetic force, the second telescopic rod is retracted, so that the second light-shielding magnetic sheet 1221 can be moved in a guiding manner, and the light transmission cannot be influenced.
As shown in fig. 1 and 2, in one embodiment, the vehicle lamp 100 further includes a first damping element 151 and a second damping element 152, the first damping element 151 is disposed between one end of the first guide 141 and the light transmissive cover 130, and the second damping element 152 is disposed between one end of the second guide 142 and the light transmissive cover 130. In this way, the first damping element 151 can eliminate the shaking of the first shading magnetic sheet 1211 during the moving process, and the second damping element 152 can eliminate the shaking of the second shading magnetic sheet 1221 during the moving process, so as to ensure the uniformity of the area change of the light-transmitting area 123, and further ensure the uniform emergence of light, and avoid the occurrence of missing or shaking due to shaking. The first and second damping elements 151 and 152 may be spring dampers, viscous dampers, or other elements capable of damping vibration or jitter. The first and second damping elements 151 and 152 may be disposed on an inner wall of the mounting cavity 131 by bonding or welding.
As shown in fig. 1 and fig. 2, in the above embodiment, the side surface of the first light-shielding magnetic sheet 1211 facing the light emitter 110 is set as the first arc surface 1212, the side surface of the second light-shielding magnetic sheet 1221 facing the light emitter 110 is set as the second arc surface 1222, and both the first arc surface 1212 and the second arc surface 1222 are matched with the outer surface of the light emitter 110. Therefore, the first and second light-shielding magnetic sheets 1211 and 1221 can be better attached to the surface of the light-emitting body 110, so that the light-emitting body 110 can be better shielded, as long as the first and second light-shielding magnetic sheets 1211 and 1221 do not move relative to the light-emitting body 110, the light emitted by the light-emitting body 110 cannot penetrate through the light-emitting body 110 or cannot penetrate through the light-emitting body 110 in a large area, and further, when the first and second light-shielding magnetic sheets 1211 and 1221 are far away from the light-emitting body 110, the brightness of the vehicle lamp 100 is gradually improved.
As shown in fig. 1 and fig. 2, on the basis of the above embodiment, the vehicular lamp 100 further includes a wireless power supply module 160 and a wireless power receiving module (not shown), the wireless power receiving module is electrically connected to the light emitting device 110, and the wireless power supply module 160 and the wireless power receiving module can be electrically connected; when the wireless power supply module 160 is powered on, the light emitting body 110 is turned on, and the light emitting body 110 moves away from the wireless power supply module 160; when the wireless power supply module 160 is powered off, the light emitting body 110 is turned off, and the light emitting body 110 moves toward the direction approaching the wireless power supply module 160. Thus, the electrical connection between the wireless power supply module 160 and the wireless power receiving module is utilized to supply electric energy to the light emitting body 110, and compared with the traditional form of utilizing a wire for connection, the wiring is reduced, and the structure is simple. Meanwhile, when the light-emitting body 110 is turned on, the light-emitting body 110 can move in a direction away from the wireless power supply module 160, so that the light-emitting body 110 presents a suspension effect; when the light 110 is turned off, it can be reset. The distance and the approach of the light 110 to the wireless power supply module 160 are preferably realized by magnetic force, for example, an electromagnet is added, and the repulsion and the attraction are realized by switching on and off the electromagnet.
As shown in fig. 1 and fig. 2, further, the car light 100 further includes a shielding member 170, the shielding member 170 is disposed in the installation cavity 131 and divides the installation cavity 131 into a first cavity 1311 and a second cavity 1312, the wireless power supply module 160 is disposed in the first cavity 1311, and the wireless power receiving module and the light emitter 110 are disposed in the second cavity 1312; when the wireless power supply module 160 is powered on, the light emitter 110 is turned on, and the light emitter 110 moves away from the shielding member 170; when the wireless power supply module 160 is powered off, the light emitter 110 is turned off, and the light emitter 110 moves toward the direction close to the shielding member 170. In this way, the mounting cavity 131 is divided into the first cavity 1311 and the second cavity 1312 which are distributed along the light emitting direction in the front and back direction by the shielding member 170, and the wireless power supply module 160 is disposed in the first cavity 1311 behind the mounting cavity, so that the wireless power supply module 160 can be shielded, and the wireless power supply module 160 cannot be seen from the outside when the light emitting body 110 is turned on. Meanwhile, when the illuminant 110 is turned off, the illuminant 110 can be placed on the light-shielding member, and the light-shielding member is used for supporting the illuminant 110. The shield 170 can be a shutter, a baffle, or other element capable of dividing the mounting chamber 131 into two chambers.
