Referring to fig. 1, fig. 1 is a schematic diagram illustrating a vehicle lamp 1 according to an embodiment of the application. The following describes in detail a vehicle lamp 1 according to an embodiment of the present application with reference to fig. 1. As shown in fig. 1, the lamp 1 of the present application includes a light emitting chip 10, a reflector 20, and a lens 30.

Optionally, the light emitting chip 10 is used for emitting a light beam, and the light emitting chip 10 is disposed inside the reflecting surface of the reflector 20. The light emitting chip 10 may include a plurality of light emitting diodes or lasers distributed in an array, which is not limited herein.

In the present embodiment, the reflecting surface of the reflector 20 includes a plurality of reflecting curved surfaces 40 respectively having different reflecting curves, the reflecting curved surfaces 40 are used for reflecting and converging the light beams emitted from the light emitting chip 10 to form a plurality of sub-light beams with different transmission angles, and the reflecting curved surfaces 40 are in one-to-one correspondence with the sub-light beams. The cross section of the reflector 20 is a half-revolution paraboloid, and the cross section of each reflecting curved surface 40 arranged in the reflector 20 is an ellipsoid. The curvature of the reflection curve corresponding to the reflection curved surfaces 40 of the reflector 20 in the outgoing direction of the lamp 1 gradually decreases, and the included angle between the outgoing direction of the sub-beams and the outgoing direction of the lamp 1 gradually increases.

Further, a lens 30 is further disposed on the outgoing light path of the vehicle lamp 1, and the lens 30 is located at the light outlet of the reflector 20, where the lens 30 is configured to converge a plurality of sub-beams emitted from the plurality of reflective curved surfaces 40 in the reflector 20, so as to project the plurality of sub-beams to form a plurality of sub-spots, and the plurality of sub-spots are partially overlapped with each other at a distance to form a target illumination spot with a cut-off line. The lens 30 may be a circular convex lens or a square convex lens, and the lens 30 may be designed into a convex lens with other shapes according to market demands, which is not limited herein.

Specifically, after each sub-beam passes through the lens 30, a corresponding sub-spot is formed at the light exit of the lens 30, a plurality of sub-beams incident from the light entrance surface of the lens 30 form a plurality of sub-spots at the light exit of the lens 30, and the plurality of sub-spots are partially overlapped with each other at a distance to form a target illumination spot with a cutoff line.

In this embodiment, after the light beams emitted from the same light emitting chip 10 are reflected and converged by the reflective curved surface 40 with different reflective curves in the reflective bowl 20, the lens 30 converges a plurality of sub-light beams emitted from the reflective bowl 20 with different transmission angles to form a plurality of sub-light spots with overlapping areas between adjacent light spots, so as to further overlap and form the target illumination light spot.

When the lamp 1 is applied to low beam lighting of a vehicle, the target lighting spot is a low beam lighting spot, and since there is an overlapping area between the plurality of sub-spots, even if there is a low assembly accuracy between the plurality of reflective curved surfaces 40, there is no gap between the plurality of sub-spots, which causes a dark area in the final low beam lighting spot of the low beam, and affects night safe driving of the driver.

In some embodiments, the number of reflective surfaces 40 in the reflector 20 may be two, three, four, etc., without limitation. The curvature of the reflective curved surfaces 40 and the number of reflective curved surfaces 40 in the reflector 20 of the vehicle lamp 1 can be designed based on the shape of the target illumination light spot required in different application scenes, so that a plurality of sub light spots formed at the light emergent position of the lens 30 can be overlapped to form the required target illumination light spot.

The vehicle lamp 1 of the embodiment of the application includes: a light emitting chip 10 for emitting a light beam; the light-emitting chip 10 is arranged in a reflecting surface of the reflecting bowl 20, the reflecting surface comprises a plurality of reflecting curved surfaces 40 respectively provided with different reflecting curves, the reflecting curved surfaces 40 are used for reflecting and converging light beams so as to form a plurality of sub-light beams with different transmission angles, and the reflecting curved surfaces 40 are in one-to-one correspondence with the sub-light beams; and a lens 30, wherein the lens 30 is disposed on an outgoing light path of the plurality of sub-beams, and is used for projecting the plurality of sub-beams to form a plurality of sub-spots, and the plurality of sub-spots are partially overlapped with each other at a distance to form a target illumination spot with a cutoff line. Based on this, after the reflection curved surface 40 with different reflection curves in the reflector 20 reflects and converges the light beams emitted by the same light emitting chip 10, the lens 30 converges the sub-light beams with different transmission angles emitted by the reflector 20, so that a plurality of sub-light spots with overlapping areas can be formed, and the target illumination light spots are formed by overlapping the remote parts of the lens 30, so that the number of the reflection curved surfaces 40 and the reflection curves of the reflection curved surfaces 40 in the reflector 20 of the car lamp 1 are designed, and the miniaturized design of the car lamp 1 is satisfied, and meanwhile, the miniaturized design of the car lamp 1 is applicable to the illumination requirements of vehicles in different application scenes. Meanwhile, because an overlapping area exists between sub-light spots formed by the light beams emitted by each reflecting curved surface 40, the assembly precision requirement of the reflecting curved surfaces 40 is low, and therefore the manufacturing difficulty of the car lamp 1 is reduced.

As an implementation manner, as shown in fig. 2, fig. 2 shows a schematic structural diagram of a vehicle lamp according to another embodiment of the present application. The number of the plurality of reflecting curved surfaces in the reflector 20 is three, that is, the reflector 20 includes a first reflecting curved surface 41, a second reflecting curved surface 42 and a third reflecting curved surface 43 sequentially distributed along the light emitting direction.

In the present embodiment, the first reflective curved surface 41 is used for reflecting the light beam emitted from the light emitting chip 10 to form a first sub-beam, the second reflective curved surface 42 is used for reflecting the light beam emitted from the light emitting chip 10 to form a second sub-beam, and the third reflective curved surface 43 is used for reflecting the light beam emitted from the light emitting chip 10 to form a third sub-beam. The image plane of the sub-beam formed by reflection of each reflecting curved surface coincides with the focal plane of the lens 30, and the lens 30 can converge the sub-beams formed by reflection of the reflecting curved surfaces, so that the sub-beams can exit uniformly after being refracted by the lens 30, and the sub-beams are partially overlapped with each other at the light exit of the lens 30 to form a target illumination spot with uniform brightness.

Specifically, the first sub-beam emitted from the first reflective curved surface 41 passes through the lens 30 and forms a first sub-spot at the light exit of the lens 30; the second sub-beam emitted by the second reflecting curved surface 42 passes through the lens 30 and forms a second sub-spot at the light emergent position of the lens 30; the third sub-beam emitted from the third reflective curved surface 43 passes through the lens 30 and forms a third sub-spot at the light exit of the lens 30.

As shown in fig. 3, fig. 3 shows a schematic view of the target illumination spot 50 of the vehicle lamp of fig. 2. In this embodiment, the included angles between the transmission directions of the first sub-beam, the second sub-beam and the third sub-beam and the exit direction of the vehicle lamp are gradually increased, and the first sub-beam corresponding to the first sub-beam, the second sub-beam corresponding to the second sub-beam, the second sub-beam 52 corresponding to the second sub-beam and the third sub-beam corresponding to the third sub-beam are partially overlapped with each other at the light exit of the lens 30 to form the target illumination light spot 50.

Alternatively, the first reflective curved surface 41 is the reflective curved surface with the largest curvature among the three reflective curved surfaces, and after the first reflective curved surface 41 reflects the light beam emitted by the light emitting chip 10, the first sub-light beam formed by reflection of the first reflective curved surface 41 forms a first sub-light spot at the light emitting position of the lens 30 after passing through the lens 30. As shown in fig. 4, fig. 4 shows a schematic view of a first sub-spot 51 corresponding to the first sub-beam in fig. 2, the first sub-spot 51 constituting a cutoff line and a top light intensity portion of the target illumination spot.

Alternatively, the curvature of the second reflective curved surface 42 is smaller than the curvature of the first reflective curved surface 41 and larger than the curvature of the third reflective curved surface 43, and after the second reflective curved surface 42 reflects the light beam emitted from the light emitting chip 10, the second sub-beam formed by reflection of the second reflective curved surface 42 forms a second sub-spot at the light emitting position of the lens 30 after passing through the lens 30. As shown in fig. 5, fig. 5 shows a schematic view of a second sub-spot 52 corresponding to the second sub-beam in fig. 2, the second sub-spot 52 constituting a middle light intensity portion of the target illumination spot.

Alternatively, the third reflective curved surface 43 is a reflective curved surface with the smallest curvature among the three reflective curved surfaces, and after the third reflective curved surface 43 reflects the light beam emitted from the light emitting chip 10, the third sub-light beam reflected by the third reflective curved surface 43 forms a third sub-light spot at the light emitting position of the lens 30 after passing through the lens 30. As shown in fig. 6, fig. 6 shows a schematic view of a third sub-spot 53 corresponding to the third sub-beam in fig. 2, the third sub-spot 53 constituting the bottom light intensity portion of the target illumination spot.

In the embodiment of the application, the first reflecting curved surface 41, the second reflecting curved surface 42 and the third reflecting curved surface 43 with gradually reduced curvature are arranged in the reflector 20, so that the sub-beam reflected and output by each reflecting curved surface can form a sub-light spot at the light emergent position of the lens 30 correspondingly, and a plurality of sub-light spots are mutually partially overlapped to form a target illumination light spot, thereby meeting the vehicle illumination requirement under the miniaturized design of the vehicle lamp. Meanwhile, when the light beams emitted by each reflecting curved surface form sub light spots after passing through the lens 30, the adjacent sub light spots can be partially overlapped with each other, so that the assembly precision requirement of a plurality of reflecting curved surfaces is lower, and the manufacturing difficulty of the car lamp is reduced.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a vehicle lamp according to another embodiment of the application. In the present application, the lamp includes a light emitting chip 10, a reflector 20, and a lens 30.

Specifically, after the light beam is emitted from the light emitting chip 10 disposed inside the reflecting surface of the reflecting bowl 20, the light beam is reflected and converged by the plurality of reflecting curved surfaces 40 of the reflecting bowl 20 to form a plurality of sub-light beams with different transmission angles, and the sub-light beams are emitted to the light incident position of the lens 30. The lens 30 is disposed on an outgoing light path of the vehicle lamp, and the lens 30 is configured to converge the plurality of sub-beams, so that the converged plurality of sub-beams form a target illumination spot at an outgoing light position of the lens 30.

Optionally, the vehicle lamp further comprises a heat sink 60 and a lens holder 70. The heat sink 60 is provided with the light emitting chip 10 and the reflector 20, and the light emitting chip 10 generates a large amount of heat in the process of emitting light beams, and the reflector 20 is used as an accessory of the vehicle lamp, which directly contacts the light emitting chip 10, and receives a large amount of heat of the light emitting chip 10, and the heat sink 60 is used for efficiently cooling the light emitting chip 10 and the reflector 20, so that the temperature of the light emitting chip 10 and the reflector 20 in the use process is reduced. The lens support 70 is used for fixing the lens 30, and the lens support 70 and the heat sink 60 are integrally formed to increase the heat dissipation area of the light emitting chip 10.

In this embodiment, the design of integrally forming the lens support 70 and the heat sink 60 increases the heat dissipation area of the light emitting chip 10, has a good heat dissipation effect, and can rapidly dissipate the heat generated when the light emitting chip 10 emits the light beam, thereby reducing the temperature rise speed of the light emitting chip 10 and the reflector 20 when the light emitting chip 10 emits the light beam, and reducing the brightness decay speed of the light beam emitted by the light emitting chip 10.

The automobile lamp comprises a high beam and a low beam, the effective illumination distance of the low beam is short, the effective illumination distance of the high beam is long, and the high beam and the low beam are switched to illuminate the road in front of the automobile. The high beam angle is long, so that the sight line can be improved, and the observation visual field can be enlarged; the low-beam angle is low and the distance is short, so that glaring can not be caused to drivers of opposite sides. If a high beam is used when meeting at night, the opposite driver cannot see the road surface clearly due to strong light and cannot judge the accurate position of the vehicle, so that the probability of accidents is increased. The illumination beam of the lamp is required to satisfy the function of preventing glare while satisfying the illumination of the road ahead when the vehicle is traveling at night. Based on this, a cut-off line with a significant change in brightness appears in the target illumination spot formed by the set light beam, which is called a low-beam cutoff line of the automobile, so that only the light beam below the cutoff line has high brightness, and the safety of the driver in night driving can be improved.

In this embodiment, as shown in fig. 8, fig. 8 shows a schematic cross-sectional view of the lamp provided in fig. 7. The lamp is provided with a cutoff panel 80, and the cutoff panel 80 is disposed on the lens holder 70 and at the light outlet of the reflector 20.

As shown in fig. 9, fig. 9 shows a schematic view of the target illumination spot 54 of the vehicle lamp of fig. 7. The cutoff line plate 80 is used to block a portion of the light beam emitted from the reflector 20 that falls on the cutoff line plate 80, so that the light beam emitted from the lamp can have a cutoff line in the target illumination spot 54 that can be formed at the light exit of the lens 30.

After the light beam emitted by the light emitting chip 10 in the car lamp is emitted through the lens 30, a low beam illumination light spot with a clear cut-off line is emitted obliquely to the ground, and the appropriate height of the cut-off line is set to prevent dazzling of drivers or pedestrians in the car lamp using process, so that the drivers can see a longer distance in front of the car, and the night driving safety of the car is improved.

Further, the vehicle lamp further includes a first mirror 90 and a second mirror 1000, where the first mirror 90 and the second mirror 1000 are used for reflecting the light beam emitted from the light emitting chip 10 to generate a light spot with a set shape above the cutoff line. The first reflecting mirror 90 is disposed on the reflecting bowl 20, and the first reflecting mirror 90 is located at the light outlet of the reflecting bowl 20, and the first reflecting mirror 90 is configured to reflect the light beam emitted from the light emitting chip 10 to the second reflecting mirror 1000. The second reflecting mirror 1000 is disposed on the lens support 70, and the second reflecting mirror 1000 is disposed adjacent to the cutoff line plate 80, and the second reflecting mirror 1000 is configured to receive and reflect the light beam emitted from the first reflecting mirror 90 to the lens 30, so that the target illumination spot 54 formed by the light emitting and emitting of the lens 30 includes the spot with the set shape above the cutoff line shown in fig. 9.

Alternatively, when the vehicle lamp is a dipped headlight, the beam emitted from the second reflector 1000 can radiate a longer distance to the vehicle front after passing through the lens 30, and the beam emitted from the second reflector 1000 is a road sign illumination beam. The light spot formed by the road sign illumination beam after passing through the lens 30 can be projected onto the road sign and the related indication board at both sides of the road, so that the driver can acquire the related road indication information.

In this embodiment, by providing the first reflector 90 and the second reflector 1000 in the vehicle lamp, the target illumination spot 54 formed by the light beam emitted from the vehicle lamp can include a spot with a set shape above the cut-off line for road sign illumination, so as to meet the night use requirement of the vehicle.

In the present embodiment, the cutoff line plate 80 for forming the outgoing light beam into the target illumination spot having the cutoff line is included in the vehicle lamp, so that only the light beam below the cutoff line has high brightness, and the safety of the driver in driving at night can be improved. Meanwhile, the vehicle lamp further comprises the first reflecting mirror 90 and the second reflecting mirror 1000, so that the target lighting light spot comprises a light spot with a set shape above the cut-off line, namely, a road sign lighting light spot, and a driver can acquire related road indication information, and the low beam lighting requirement of the driver during driving at night is further met.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and are not limiting; although the application has been described in detail with reference to the foregoing embodiments, it will be appreciated by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not drive the essence of the corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present application.
