In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual manufacture.
[0049] As described in the background section, the current dynamic lighting of atmosphere lamp needs to use a large number of independent light sources and complex electronic control to achieve, which has a high cost.
[0050] Therefore, the embodiments of the present application provide an optical system of a vehicle lamp, Figure 1 The structural schematic diagram of the optical system of the vehicle lamp provided by the embodiments of the present application is shown, Figure 2A side view of the optical system of the vehicle lamp is shown in Figure 1 A side view of the optical system of the vehicle lamp is shown in Figure 1 A side view of the optical system of the vehicle lamp is shown in Figure 2 The optical system of the vehicle lamp shown in
[0051] Figure 3 A side view of the optical system of the vehicle lamp is shown in Figure 1 A side view of the optical system of the vehicle lamp is shown in Figure 2 A side view of the optical system of the vehicle lamp is shown in Figures 1-3 The thick-walled part 300 shown in
[0052] It should be noted that, in the present application, for the convenience of description, the thick-walled part 300 is divided into the first part 310, the connecting part 320 and the second part 330 for description, actually, the first part 310, the connecting part 320 and the second part 330 are integrally formed structures.
[0053] A side view of the optical system of the vehicle lamp is shown in Figures 1-3 The connecting part 320 shown in
[0054] A side view of the optical system of the vehicle lamp is shown in Figures 1-3 The light curtain board 400 shown in
[0055] Figure 4 A side view of the optical system of the vehicle lamp is shown in Figure 1 A side view of the optical system of the vehicle lamp is shown in Figure 2 A side view of the optical system of the vehicle lamp is shown in Figures 1-4 The light curtain board 400 shown in Figure 5 A side view of the optical system of the vehicle lamp is shown in Figure 1 A side view of the optical system of the vehicle lamp is shown in Figure 2The lightening effect diagram of the optical system of the vehicle lamp shown in the application can realize the lightening function of the main function lamp such as the position lamp, the brake lamp and the steering lamp when the first light exit surface D1 is lightened.
[0056] In combination Figures 1-3 As shown, the first part 310 of the thick-walled piece 300 has a first side surface B1 on the first side along the second direction Z and a second side surface B2 on the second side along the second direction Z; the second part 330 of the thick-walled piece 300 has a third side surface B3 on the first side along the second direction Z and a fourth side surface B4 on the second side along the second direction Z; and, along the second direction Z, the third side surface B3 is inwardly recessed relative to the first side surface B1 and / or the fourth side surface B4 is inwardly recessed relative to the second side surface B2; that is, at least one side surface of the second part 330 of the thick-walled piece 300 along the second direction Z is inwardly recessed relative to the same side surface of the first part 310 thereof.
[0057] Thus, as Figure 6 shown, the light emitted by the light source 100 is collimated by the collimator 200 and then is incident to the first reflecting surface S1 of the thick-walled piece 300, and the light in the middle region of the second direction Z, i.e. the main light, is reflected by the first reflecting surface S1 and then is transmitted through the first part 310, the connecting part 320 and the second part 330 of the thick-walled piece 300 and then is emitted from the first light exit surface D1, thereby lightening the first light exit surface D1 and realizing the lightening of the function lamp; at the same time, as Figure 7 shown, since at least one side surface of the second part 330 of the thick-walled piece 300 along the second direction Z is inwardly recessed relative to the same side surface of the first part 310 thereof, the light emitted by the light source 100 and collimated by the collimator 200 and then reflected by the first reflecting surface S1 can be reflected by the connecting part 320 to the light curtain board 400 and then is reflected back and forth between the back surface C1 of the light curtain board 400 and the second light exit surface D2, thereby lightening the feature pattern 410 of the second light exit surface D2 and realizing the lightening of the atmosphere lamp.
[0058] It can be seen that the optical system of the vehicle lamp provided by the embodiments of the application integrates the light curtain board 400 for the lightening of the atmosphere lamp and the thick-walled piece 300 for the lightening of the function lamp, realizes the lightening of the function lamp by the main light transmitted in the thick-walled piece 300 and lightens the light curtain board 400 by the edge light transmitted in the thick-walled piece 300, thereby lightening the atmosphere lamp, saving the use of the independent light source and electronic devices of the atmosphere lamp, greatly reducing the cost and power consumption and improving the economic benefit.
[0059] It can be understood that if the side surface of the second part 330 of the thick-walled piece 300 on one side of the second direction Z is recessed relative to the side surface on the same side of the first part 310, the connecting part 320 of the thick-walled piece 300 can be designed to make the connecting part 320 of the thick-walled piece 300 reflect the light rays emitted by the light source 100 to the inside of the light curtain plate 400 after the light rays are collimated by the collimator 200 and reflected by the first reflecting surface S1 along the edge on the same side of the second direction Z, or to make the light rays emitted by the light source 100 be reflected to the inside of the light curtain plate 400 after the light rays are collimated by the collimator 200 and reflected by the first reflecting surface S1 along the edge on one side of the second direction Z, the side surface of the second part 330 of the thick-walled piece 300 on the same side of the second direction Z can be recessed relative to the side surface on the same side of the first part 310, and the optical design of the connecting part 320 of the thick-walled piece 300 can be combined to achieve the above-mentioned purpose.
[0060] Optionally, in a first implementation, the side surface of the second part 330 of the thick-walled piece 300 on the first side of the second direction Z is recessed relative to the side surface on the same side of the first part 310, and the connecting part 320 of the thick-walled piece 300 reflects the light rays emitted by the light source 100 to the inside of the light curtain plate 400 after the light rays are collimated by the collimator 200 and reflected by the first reflecting surface S1 along the edge on the first side of the second direction Z.
[0061] Specifically, as shown in Figure 8 Figure 8 FIG. 6 shows a side view of the light source 100, the collimator 200, the thick-walled piece 300 and the light curtain plate 400 in another optical system of the vehicle lamp provided by the embodiment of the present application, and it can be seen that along the second direction Z, the third side surface B3 of the second part 330 of the thick-walled piece 300 is recessed relative to the first side surface B1 of the first part 310, and the fourth side surface B4 of the second part 330 of the thick-walled piece 300 is flush with the second side surface B2 of the first part 310; at this time, the connecting part 320 of the thick-walled piece 300 can be provided to include a second reflecting surface S2, the second reflecting surface S2 is connected with the third side surface B3, the second reflecting surface S2 and the first reflecting surface S1 are oppositely arranged along the first direction X, and at least partially overlap along the second direction Z, that is, along the second direction Z, the second reflecting surface S2 is at least partially located between the first side surface B1 and the third side surface B3.
[0062] In this way, referring to Figure 8 As shown, the light emitted by the light source 100 is collimated by the collimator 200 and reflected by the first reflecting surface S1, and then the light rays in the edge region of the first side in the second direction Z can be reflected by the second reflecting surface S2 into the light curtain plate 400. It can be understood that the light rays in the edge region of the first side in the second direction Z can be directly incident on the second reflecting surface S2 after the light emitted by the light source 100 is collimated by the collimator 200 and reflected by the first reflecting surface S1, and / or the light rays in the edge region of the first side in the second direction Z can be incident on the first side surface B1 first, and then incident on the second reflecting surface S2 after being reflected by the first side surface B1.
[0063] In the first implementation, optionally, as shown in Figure 8 As shown, the included angle between the first reflecting surface S1 and the first side surface B1 counterclockwise can be 45°, and the included angle between the second reflecting surface S2 and the third side surface B3 clockwise can be 45°, so that when the light source 100 and the collimator 200 are located at the first side of the thick-walled part 300 in the second direction Z and at the corresponding region of the first reflecting surface S1 in the second direction Z, the width of the first reflecting surface S1 in the first direction X is equal to the width of the first reflecting surface S1 in the second direction Z, both of which are W; the thickness of the second part 330 of the thick-walled part 300 in the second direction Z is H; the third side surface B3 of the second part 330 of the thick-walled part 300 in the second direction Z is recessed from the first side surface B1 of the first part 310 by a distance h1; and W=H+h1. Such a setting makes the design of the thick-walled part relatively simple, and the light rays in the edge region of the first side in the second direction Z can be better reflected by the second reflecting surface S2 into the light curtain plate 400 after the light emitted by the light source 100 is collimated by the collimator 200 and reflected by the first reflecting surface S1.
[0064] It can be understood that in order to minimize the impact on the optical efficiency of the first light emitting surface D1, H and h1 can be reasonably designed, so that the lighting of the atmosphere lamp (corresponding to the second light emitting surface D2) can be realized without weakening the optical efficiency of the functional lamp (corresponding to the first light emitting surface D1).
[0065] In the first implementation, optionally, as shown in Figure 8 As shown, the light curtain plate 400 and the thick-walled part 300 can be an integrally formed structure, specifically, the second reflecting surface S2 is connected with the second light emitting surface D2, and the first side surface B1 is directly connected with the back surface C1 or connected with the back surface C1 through a step surface. It can be understood that the light curtain plate 400 and the thick-walled part 300 are an integrally formed structure, that is, the integrally formed structure is a thick-walled light curtain composite structure, so that only one mold is needed to form the thick-walled part 300 and the light curtain plate 400 at the same time when preparing, which greatly reduces the cost and energy consumption, and has higher economic benefits.
[0066] Optionally, the second implementation is as follows: not only is the side of the second part 330 of the thick-walled member 300 along the first side of the second direction Z recessed relative to the side of the first part 310 on the same side, but the connecting part 320 of the thick-walled member 300 also reflects the light emitted by the light source 100 into the light curtain plate 400 after being collimated by the collimator 200 and reflected by the first reflecting surface S1, along the edge light of the first side of the second direction Z. Moreover, the side of the second part 330 of the thick-walled member 300 along the second side of the second direction Z recessed relative to the side of the first part 310 on the same side, and the connecting part 320 of the thick-walled member 300 also reflects the light emitted by the light source 100 into the light curtain plate 400 after being collimated by the collimator 200 and reflected by the first reflecting surface S1, along the edge light of the second side of the second direction Z.
[0067] Specifically, such as Figure 3 As shown, along the second direction Z, the third side B3 of the second portion 330 of the thick-walled member 300 is recessed relative to the first side B1 of its first portion 310, and along the second direction Z, the fourth side B4 of the second portion 330 of the thick-walled member 300 is recessed relative to the second side B2 of its first portion 310; at this time, not only does the connecting portion 320 of the thick-walled member 300 include a second reflective surface S2, which is connected to the third side B3, and the second reflective surface S2 and the first reflective surface S1 are disposed opposite to each other along the first direction X, and along the second direction Z, the second reflective surface S2 and the first reflective surface S1 at least partially overlap, that is, along the second direction Z, the second reflective surface S2 is at least partially located between the first side B1 and the third side B3; moreover, the connecting portion 320 of the thick-walled member 300 also includes a third reflective surface S3 and a fourth reflective surface S4 disposed opposite to each other along the second direction Z, the third reflective surface S3 being located between the second side B2 and the fourth side B4, and the fourth reflective surface S4 being located between the first side B1 and the second reflective surface S2.
[0068] Thus, on the one hand, such as Figure 7 As shown, the light emitted from the light source 100 is collimated by the collimator 200 and reflected by the first reflecting surface S1. The light rays along the edge region of the first side in the second direction Z are reflected by the second reflecting surface S2 into the light curtain plate 400. It can be understood that the light emitted from the light source 100, after being collimated by the collimator 200 and reflected by the first reflecting surface S1, can directly enter the second reflecting surface S2 along the edge region of the first side in the second direction Z, and / or, the light rays along the edge region of the first side in the second direction Z can first enter the first side surface B1, be reflected by the first side surface B1, and then enter the second reflecting surface S2.
[0069] On the other hand, also Figure 7As shown, the light rays emitted by the light source 100 are collimated by the collimator 200 and reflected by the first reflecting surface S1, and then the light rays in the edge region of the second side along the second direction Z are reflected by the third reflecting surface S3 and the fourth reflecting surface S4 in turn, and then reflected by the second reflecting surface S2 into the light curtain board 400. It can be understood that the light rays in the edge region of the second side along the second direction Z can be directly incident on the third reflecting surface S3 after the light rays emitted by the light source 100 are collimated by the collimator 200 and reflected by the first reflecting surface S1, and / or the light rays in the edge region of the second side along the second direction Z can be first incident on the second side B2 and then incident on the third reflecting surface S3 after being reflected by the second side B2.
[0070] In the second implementation, optionally, as shown in FIG. 4, the connecting portion 320 of the thick-walled member 300 can further include a fifth side B5 and a sixth side B6, the second side B2 is connected with the fourth side B4 through the third reflecting surface S3 and the fifth side B5 in turn, and the first side B1 is connected with the second reflecting surface S2 through the fourth reflecting surface S4 and the sixth side B6 in turn. Figure 3
[0071] In the second implementation, optionally, as shown in FIG. 4, the connecting portion 320 of the thick-walled member 300 can further include a fifth side B5 and a sixth side B6, the second side B2 is connected with the fourth side B4 through the third reflecting surface S3 and the fifth side B5 in turn, and the first side B1 is connected with the second reflecting surface S2 through the fourth reflecting surface S4 and the sixth side B6 in turn.

[0072] It can be understood that, in order to minimize the impact on the optical efficiency of the first light exit surface D1, H, h1 and h2 can be reasonably designed, so that the lighting of the atmosphere lamp (corresponding to the second light exit surface D2) can be realized without weakening the optical efficiency of the functional lamp (corresponding to the first light exit surface D1).
[0073] Further, as shown in Figure 3 , the thickness T of the light curtain plate 400 along the first direction X can be equal to the sum of the distance h1 by which the third side B3 is inwardly recessed relative to the first side B1 along the second direction Z and the distance h2 by which the fourth side B4 is inwardly recessed relative to the second side B2, i.e. T = h1 + h2, that is, T = W - H.
[0074] In the second implementation manner, as shown in Figure 3 , the light curtain plate 400 and the thick-walled piece 300 can be an integrally formed structure. Specifically, the second reflecting surface S2 is connected with the second light exit surface D2, and the fourth reflecting surface S4 is directly or through a sixth side B6 connected with the back surface C1, and the sixth side B6 is not connected with the second reflecting surface S2. It can be understood that, when the light curtain plate 400 and the thick-walled piece 300 are an integrally formed structure, i.e. the integrally formed structure is a thick-walled light curtain composite structure, only one mold is needed to form the thick-walled piece 300 and the light curtain plate 400 at the same time, so that the cost and energy consumption are greatly reduced, and there is higher economic benefit.
[0075] Optionally, the third implementation manner is that the second part 330 of the thick-walled piece 300 is inwardly recessed relative to the same side surface of the first part 310 along the second direction Z, and the connecting part 320 of the thick-walled piece 300 reflects the light emitted by the light source 100 to the light curtain plate 400 after being collimated by the collimator 200 and reflected by the first reflecting surface S1 along the edge of the second side along the second direction Z.
[0076] Specifically, as shown in Figure 9 , the fourth reflecting surface S4 is directly or through a sixth side B6 connected with the back surface C1, and the sixth side B6 is not connected with the second reflecting surface S2. Figure 9A side view schematic diagram of the light source 100, the collimator 200, the thick-walled piece 300 and the light curtain board 400 in the optical system of the still another vehicle lamp provided by the embodiment of the application is shown, and it can be seen that, along the second direction Z, the fourth side B4 of the second part 330 of the thick-walled piece 300 is recessed relative to the second side B2 of the first part 310 thereof, and the third side B3 of the second part 330 of the thick-walled piece 300 is flush with the first side B1 of the first part 310 thereof; at this time, not only does the connecting part 320 of the thick-walled piece 300 include the second reflecting surface S2, the second reflecting surface S2 is connected with the third side B3, and the second reflecting surface S2 and the first reflecting surface S1 are oppositely arranged along the first direction X; but the connecting part 320 of the thick-walled piece 300 also includes the third reflecting surface S3 and the fourth reflecting surface S4 which are oppositely arranged along the second direction Z, the third reflecting surface S3 is located between the second side B2 and the fourth side B4, and the fourth reflecting surface S4 is located between the first side B1 and the second reflecting surface S2; and different from the second implementation manner is that, along the second direction Z, the second reflecting surface S2 and the first reflecting surface S1 can not overlap.
[0077] In this way, referring to FIG. 1, Figure 9 it can be seen that the light rays emitted by the light source 100 are collimated by the collimator 200 and reflected by the first reflecting surface S1, and then the light rays in the edge region of the second side along the second direction Z are reflected by the third reflecting surface S3 and the fourth reflecting surface S4 in turn and then reflected by the second reflecting surface S2 into the light curtain board 400. It can be understood that the light rays emitted by the light source 100 can be directly incident on the third reflecting surface S3 after being collimated by the collimator 200 and reflected by the first reflecting surface S1, and / or the light rays in the edge region of the second side along the second direction Z can be first incident on the second side B2 and then incident on the third reflecting surface S3 after being reflected by the second side B2.
[0078] Under the third implementation manner, optionally, as shown in FIG. 1, Figure 9 the connecting part 320 of the thick-walled piece 300 can further include the fifth side B5 and the sixth side B6, the second side B2 is connected with the fourth side B4 through the third reflecting surface S3 and the fifth side B5 in turn, and the first side B1 is connected with the second reflecting surface S2 through the fourth reflecting surface S4 and the sixth side B6 in turn.
[0079] Under the third implementation manner, optionally, as shown in FIG. 1, Figure 9As shown, the first reflective surface S1 can form an angle of 45° with the first side B1 in a counterclockwise direction, the second reflective surface S2 can form an angle of 45° with the third side B3 in a clockwise direction, the third reflective surface S3 can form an angle of 135° with the second side B2 in a counterclockwise direction, and the fourth reflective surface B4 can form an angle of 135° with the first side B1 in a counterclockwise direction. In this way, when the light source 100 and the collimator 200 are located at the first side of the thick-walled member 300 along the second direction Z and at the corresponding area of the first reflective surface S1 along the second direction Z, the width of the first reflective surface S1 along the first direction X is equal to the width of the first reflective surface S1 along the second direction Z, both of which are W; the thickness of the second part 330 of the thick-walled member 300 along the second direction Z is H; the fourth side B4 of the second part 330 of the thick-walled member 300 is recessed from the second side B2 of the first part 310 along the second direction Z by a distance h2; and W = H + h2. This arrangement makes the design of the thick-walled member relatively simple, and the light emitted by the light source 100 can be better reflected by the second reflective surface S2 into the edge area of the second side along the second direction Z after being collimated by the collimator 200 and reflected by the first reflective surface S1.
[0080] It can be understood that, in order to minimize the impact on the optical efficiency of the first light exit surface D1, H and h2 can be reasonably designed so as to achieve the lighting of the atmosphere lamp (corresponding to the second light exit surface D2) without weakening the optical efficiency of the functional lamp (corresponding to the first light exit surface D1).
[0081] In the third implementation manner, optionally, Figure 9 As shown, the light curtain board 400 and the thick-walled member 300 can be an integrally formed structure, specifically, the first reflective surface S1 is connected with the second light exit surface D2, and the fourth reflective surface S4 is connected with the back surface C1 directly or through a sixth side B6, and the sixth side B6 is not connected with the second reflective surface S2. It can be understood that, when the light curtain board 400 and the thick-walled member 300 are an integrally formed structure, i.e., the integrally formed structure is a thick-walled light curtain composite structure, only one mold is needed to form the thick-walled member 300 and the light curtain board 400 at the same time, which greatly reduces the cost and energy consumption and has higher economic benefits.
[0082] It can be understood that, in the above three implementation manners, the second implementation manner can introduce the light emitted by the light source 100 into the light curtain board 400 along the edges of both sides of the second direction Z after being collimated by the collimator 200 and reflected by the first reflective surface S1, which is better than the first implementation manner and the third implementation manner that introduce the light emitted by the light source 100 into the light curtain board 400 along the edge of one side of the second direction Z after being collimated by the collimator 200 and reflected by the first reflective surface S1, and can make the lighting effect of the second light exit surface D2 of the light curtain board 400 better and the optical utilization rate higher.
[0083] It should also be understood that, when the thick-walled part 300 and the light curtain plate 400 are an integral structure, for the convenience of description, the integral structure composed of the thick-walled part 300 and the light curtain plate 400 is divided into the thick-walled part 300 and the light curtain plate 400, but in fact the two are an integral structure.
[0084] On the basis of any of the above embodiments, optionally, in some embodiments of the present application, as shown in Figure 1 The light source 100 includes a PCB board 110 and a plurality of LED light sources 120 arranged along a third direction Y on the PCB board 110, the third direction Y intersects the first direction X and intersects the second direction Z; the collimator 200 is a plurality of collimators, and the collimator 200 is arranged one-to-one with the LED light source 100. In actual application, the third direction Y can be the vehicle width direction, that is, the left-right opposite direction of the vehicle.
[0085] It should be noted that the light source 100 and the collimator 200 can be located on the first side of the thick-walled part 300 along the second direction Z and located in the corresponding area of the first reflecting surface S1 along the second direction Z. Optionally, as shown in Figures 1-3 The first side surface B1 of the thick-walled part 300 can include a light entrance surface B11, and the light entrance surface B11 can be a convex surface, so as to make the light emitted by the LED light source 120 and collimated by the collimator 200 more incident to the first reflecting surface S1.
[0086] In fact, the collimator 200 can also be an integral structure with the thick-walled part 300, so that the cost and energy consumption are greatly reduced, and there is higher economic benefit.
[0087] In actual application, as shown in Figure 1 and Figure 2 The optical system of the vehicle lamp can further include:
[0088] A support 500 for supporting the thick-walled part 300 and the light curtain plate 400;
[0089] A decorative frame 600 located on both sides of the second part 330 of the thick-walled part 300 along the second direction Z;
[0090] And an outer cover 710 and a housing 720, the outer cover 710 surrounds the first light exit surface D1 and the second light exit surface D2, and the outer cover 710 and the housing 720 together surround the light source 100, the collimator 200, the thick-walled part 300, the light curtain plate 400, the support 500 and the decorative frame 600.
[0091] The various parts in the specification are described in a parallel and progressive manner, and each part focuses on the difference from other parts. The same and similar parts between the various parts can be referred to each other.
[0092] From the above description of disclosed embodiments, it is manifest that various modifications and variations can be made to the described embodiments, in terms of both their details and the general use, without departing from the spirit or scope of the application. Indeed, various specific feature that have been described in this specification in order to provide a thorough understanding are presented only as illustrative examples and should not be construed as limiting the scope of the application. The scope of the application should, therefore, be determined only by the scope of the claims that have now followed, along with their full equivalents.
