Description

Technical Field

[0001] The present application relates to the technical field of vehicle lighting, and in particular to a lighting system, a vehicle lamp and a vehicle. Background Art

[0002] With the emergence of LED and the development of automotive lighting, how to design a car headlight is no longer a problem. Effectively combining the cost, personalization, efficiency and performance of the headlight module has become the goal pursued by people.

[0003] Since its invention, the high and low beam integrated module has formed a variety of design forms, and the form of condenser + baffle + lens is more widely used. The design method of this form is mostly to use the condenser as a primary optical device to gather the energy of the LED and distribute it on the baffle, and use the focusing lens to image the shape of the baffle. The high beam and low beam are arranged on the upper and lower sides of the baffle, respectively, to form a high and low beam integrated module. However, in the high beam mode, when the high beam and low beam are turned on at the same time, there is a very obvious dividing line at the junction of the high and low beams, and the high beam shape has obvious defects; and the overall light pattern of the high beam is displayed on the upper part of the screen in the distance, which also has a great impact on driving safety.

[0004] In addition, the traditional technical route of the upper and lower arranged high and low beam focusing module has its own limitations. Especially when the upper and lower openings of the optical module are small, the efficiency and brightness of the module will be greatly reduced. Therefore, it cannot adapt to the current development trend of the upper and lower openings of the optical module becoming narrower and narrower. Utility Model Content

[0005] In order to solve the above problems, the technical solutions adopted in the embodiments of the present application are as follows:

[0006] The present application discloses a lighting system, comprising:

[0007] A low beam unit, used for collimating a low beam light beam that is emitted obliquely downward, and the low beam unit is arranged at the upper rear of the baffle;

[0008] A first high beam unit, used for collimating to form a first high beam light emitted straight ahead; the first high beam unit is arranged side by side on the left and right sides of the low beam unit in a horizontal direction, and at least a part of the first high beam unit is at the same height as the baffle;

[0009] a baffle plate, arranged at intervals on the light-emitting side of the low-beam unit and close to the bottom edge of the low-beam unit;

[0010] An outer lens is arranged on a side of the baffle away from the low beam unit, comprising a focusing imaging light mirror and high beam non-focus offset lenses arranged on the left and right sides of the focusing imaging light mirror in the horizontal direction;

[0011] Among them, the converging imaging mirror is opposite to the low beam unit, and is used to converge the low beam light to form a low beam light pattern; the two high beam non-focus offset lenses are directly opposite to the two first high beam units front and back, and are used to respectively offset the corresponding two groups of first high beam light in directions close to each other to form a high beam light pattern.

[0012] Compared with the prior art, this application has at least the following advantages:

[0013] In high beam mode, compared with the solution of focusing light obliquely upward to form a high beam pattern, the present application adopts a new method of emitting light straight ahead to form high beam, that is, the first high beam units on both sides of the low beam unit respectively form a first high beam light beam that is emitted straight ahead, and after being horizontally offset by the high beam non-focus offset lens, a high beam circular bright spot is formed, and the high beam non-focus offset lenses on both sides are only used to offset the first high beam lights on the left and right sides in a direction close to each other, and do not have focusing and imaging functions. Since the light emitting direction of the first high beam unit is straight ahead and at least part of the first high beam unit is at the same height as the baffle, in high beam mode, when the high beam and low beam are turned on at the same time, the high beam circular bright spot formed by the two first high beam units emitting straight ahead can just cover the horizontal dividing cutoff line formed by the baffle, thereby visually eliminating the horizontal dividing cutoff line at the junction of the high and low beams, and the high beam shape is more complete;

[0014] Compared with the solution of focusing light upward at an angle to form a high beam pattern, the present application adopts a new method of emitting light directly forward to form a high beam, and at least a part of the first high beam module is at the same height as the baffle. Therefore, the high beam pattern area facing directly forward formed by the present application will be located lower on the distant screen. After actual measurement, in the CNCAP scoring, the high beam scoring point P5 drops to near the cutoff line or even below the cutoff line, which can correspondingly improve the score and enhance driving safety.

[0015] As an optional implementation, the height of the upper edge of the light emitting surface of the first high beam unit is lower than the upper edge of the low beam unit, and the height of the center of the light emitting surface of the first high beam unit is consistent with the height of the baffle.

[0016] As an optional embodiment, it also includes: a second high beam unit, used for collimating to form a second high beam emitted obliquely upward; the converging imaging light mirror is also opposite to the second high beam unit, used for converging the second high beam to form a second high beam pattern.

[0017] As an optional implementation, the light-emitting surface of the converging imaging light mirror and the light-emitting surface of the high-beam zero-focus shift lens have the same slope at the connection point, and a smooth transition is made at the connection point.

[0018] As an optional implementation, the light entrance surface and the light exit surface of the high beam lens without focus shift are respectively inclined curved surfaces convex forward, and the light entrance surface and the light exit surface of the high beam lens without focus shift are not parallel.

[0019] As an optional implementation, in the width direction from the middle to the side of the outer lens, the thickness of the high beam zero-focus shift lens in the front-to-back direction gradually increases.

[0020] As an optional implementation, the angle between the light incident surface of the high beam zero-focus shift lens and the front-to-back direction is smaller than the angle between the light exit surface of the high beam zero-focus shift lens and the front-to-back direction.

[0021] As an optional implementation, the ratio of the horizontal dimension to the vertical dimension of the outer lens is greater than or equal to 4:1.

[0022] As an optional embodiment, the first high beam unit includes a circular concentrator, the light-emitting surface of the circular concentrator faces straight ahead and is opposite to the high beam zero-focus shift lens, and is used for collimating a first high beam light emitted straight ahead.

[0023] As an optional implementation, the low beam unit includes a plurality of low beam concentrators arranged side by side in a horizontal direction.

[0024] As an optional implementation, the second high-beam unit includes a plurality of high-beam concentrators arranged side by side in a horizontal direction.

[0025] As an optional implementation manner, the two first high beam units are respectively located on the left and right outer sides of the baffle in the width direction, and do not overlap with the projection of the baffle in the vertical plane perpendicular to the first high beam light.

[0026] The present application also discloses a vehicle lamp, on which is provided a light emitting system as described in any of the aforementioned embodiments.

[0027] The present application also discloses a vehicle, comprising the vehicle light described in any of the aforementioned embodiments.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0051] The high and low beam integrated module has formed a variety of design forms, and the form of condenser + baffle + lens is more widely used. The design method of this form is mostly that the condenser is used as a primary optical device to gather the energy of the LED and distribute it on the baffle, and the shape of the baffle is imaged by the focusing lens. For example, the low beam lens 1 and the high beam lens 2 are arranged on the upper and lower sides of the light baffle 3 respectively. In the low beam mode, the light emitted by the low beam light source 1' is focused by the low beam lens 1 and then emitted obliquely downward, and then collimated by the secondary lens 4 into the low beam, and projected at a distance to form a low beam light type at a lower position; in the high beam mode, the low beam will continue to light up, and at the same time, the light emitted by the high beam light source 2' is focused by the high beam lens 2 and then emitted obliquely upward, and then collimated by the secondary lens 4 into the high beam, and projected at a distance to form a high beam light type at an upper position.

[0052] In the case of high beam, when the high beam and low beam are turned on at the same time, there is a clear dividing line at the junction of high beam and low beam, which leads to obvious defects in the shape of high beam; and the overall light pattern of high beam is displayed at the upper position of the screen in the distance, which also has a great impact on driving safety. This problem needs to be solved urgently.

[0053] refer to Figure 2-Figure 5 , the present application provides a light emitting system, comprising:

[0054] A low beam unit 100 is used to collimate a low beam light beam that is emitted obliquely downward, and the low beam unit 100 is disposed at the upper rear of the baffle 300;

[0055] A first high beam unit 210 is used for collimating and forming a first high beam light emitted forward; the first high beam unit 210 is arranged side by side on the left and right sides of the low beam unit 100 in the horizontal direction, and at least a part of the first high beam unit 210 is at the same height as the baffle 300;

[0056] A baffle 300 is disposed at intervals on the light-emitting side of the low beam unit 100 and close to the bottom edge of the low beam unit 100;

[0057] The outer lens 400 is disposed on a side of the baffle 300 away from the low beam unit 100, and includes a focusing lens 410 and a high beam non-focus shift lens 420 disposed on the left and right sides of the focusing lens 410 in the horizontal direction;

[0058] Among them, the converging imaging light mirror 410 is opposite to the low beam unit 100, and is used to converge the low beam light to form a low beam light pattern; the two high beam non-focus offset lenses 420 are directly opposite to the two first high beam units 210 front and back, and are used to respectively offset the corresponding two groups of first high beam light in a direction close to each other to form a high beam light pattern.

[0059] During specific operation, in the low beam mode, the low beam unit 100 collimates to form a low beam light beam that is emitted obliquely downward, and after forming a horizontal dividing cutoff line through the baffle 300, a low beam light pattern is formed at a lower position of the distant screen (the low beam cutoff line is at the upper edge of the low beam light pattern).

[0060] In the high beam mode, compared with the solution of focusing light obliquely upward to form a high beam light pattern, the present application adopts a new method of emitting light straight ahead to form a high beam, that is, the first high beam units 210 on both sides of the low beam unit 100 respectively form a first high beam light beam that is emitted straight ahead, and after being horizontally offset by the high beam non-focus offset lens 420, a high beam circular bright spot is formed (the first high beam light beam basically does not pass through the baffle 300), and the high beam non-focus offset lenses 420 on both sides are only used to offset the first high beam lights on the left and right sides in directions close to each other, and do not have focusing and imaging functions (such as Figure 5 ). Since the light emitting direction of the first high beam unit 210 is toward the front and at least a part of the first high beam unit 210 is at the same height as the baffle 300, when the high beam and the low beam are turned on at the same time in the high beam mode, the circular bright spot of the high beam emitted toward the front by the two first high beam units 210 can just cover the horizontal dividing cutoff line formed by the baffle 300, thereby visually eliminating the horizontal dividing cutoff line at the junction of the high beam and the low beam, and the high beam shape is more complete;

[0061] Compared with the solution of focusing light upward at an angle to form a high beam, the present application adopts a new method of emitting light directly forward to form a high beam, and at least a part of the first high beam module is at the same height as the baffle 300. Therefore, the high beam light pattern area directly forward formed by the present application will be located lower on the distant screen. After actual measurement, in the CNCAP scoring, the high beam scoring point P5 drops to near the cutoff line or even below the cutoff line, which can correspondingly improve the score and enhance driving safety.

[0062] The convergence function of the converging imaging mirror 410 determines that it generates edge aberration at the edge interface with the air, and the edge aberration will cause obvious dispersion. The high beam afocal offset lenses 420 on both sides of the present application are integrally connected to the side of the middle converging imaging mirror 410. By fixing the afocal lenses without converging function on both sides of the converging imaging mirror 410, the converging imaging mirror 410 itself no longer has an edge interface with the air, and thus no longer has edge aberration, solving the dispersion problem.

[0063] In the present application, the first high beam unit 210 is arranged side by side on the left and right sides of the low beam unit 100 in the horizontal direction and the high beam focus-free offset lens 420 is arranged on the left and right sides of the converging imaging mirror 410 in the horizontal direction, so that the space in the horizontal width direction of the optical module can be fully utilized, which is particularly suitable for the case where the aspect ratio of the module lens size exceeds 4:1. In this case, the utilization rate of the outer lens 400 size can reach 100%; the first high beam unit 210 is arranged side by side on the left and right sides of the low beam unit 100 in the horizontal direction, and both the left and right sides emit light, which greatly increases the area of ​​the entire high beam light pattern formed, thereby improving the efficiency and brightness of the narrow-opening optical module.

[0064] Here, it should be noted that: Figure 3 , Figure 4 The front and rear directions described in this application correspond to Figure 3 The left and right directions described in this application correspond to Figure 3 The upper and lower directions described in this application correspond to Figure 4 Up and down direction.

[0065] refer to Figure 4 In some embodiments, the height of the upper edge of the light emitting surface of the first high beam unit 210 is lower than the upper edge of the low beam unit 100 , and the height of the center of the light emitting surface of the first high beam unit 210 is consistent with the height of the baffle 300 .

[0066] In this embodiment, the center of the light-emitting surface of the first high beam unit 210 is relatively low and is at the same height as the baffle 300. The center of the high beam circular bright spot formed by the two first high beam units 210 after being emitted to the front and horizontally offset by the high beam non-focus offset lens 420 just falls on the horizontal dividing cutoff line formed by the baffle 300, thereby completely covering the horizontal dividing cutoff line formed by the baffle 300. The horizontal dividing cutoff line at the junction of the high beam and the low beam is completely invisible visually, and the high beam shape is more complete. In addition, compared with the traditional design, the high beam is formed by emitting light to the front, and the height of the upper edge of the light-emitting surface of the first high beam unit 210 is lower than the upper edge of the low beam unit 100, and the height of the center of the light-emitting surface of the first high beam module is consistent with the height of the baffle 300. The overall position of the high beam light pattern area facing the front is also lower on the far screen (according to actual measurement, in the CNCAP scoring, the high beam scoring point P5 is located at the cutoff line or below), which further improves the scoring score and night driving safety.

[0067] refer to Figure 2 and Figure 8In some embodiments, it also includes: a second high beam unit 220, which is used to collimate and form a second high beam that is emitted obliquely upward; the converging imaging light mirror 410 is also opposite to the second high beam unit 220, and is used to converge the second high beam to form a second high beam type.

[0068] Specifically, in the high beam mode, the second high beam unit 220 is collimated to form a second high beam that is emitted obliquely upward, and after a horizontal dividing cutoff line is formed by the baffle 300, a second high beam pattern is formed at the upper position of the distant screen (the high beam cutoff line is at the lower edge of the high beam pattern); in this case, the second high beam pattern and the high beam circular bright spot formed by the first high beam unit 210 together form a high beam pattern, which can increase the high beam pattern area and brightness.

[0069] refer to Figure 6 In some embodiments, the light-emitting surface of the converging imaging lens 410 and the light-emitting surface 422 of the high-beam zero-focus shift lens 420 have the same slope at the connection point, and the connection point has a smooth transition.

[0070] The above arrangement can make the converging imaging lens 410 and the high beam non-focus shift lens 420 maintain uniformity in overall appearance.

[0071] Since the converging imaging lens is an outward convex lens, when the connecting part slope of the light emitting surface of the high beam lens 420 with no focus shift is consistent and smoothly transitioned, it means that the light emitting surface 422 of the high beam lens 420 with no focus shift is also an inclined surface with an acute angle to the front-to-back direction. In this case, if the light incident surface 421 of the high beam lens 420 with no focus shift is designed to be perpendicular to the front-to-back direction, the light will directly diffuse outward from the light emitting surface of the high beam lens 420 with no focus shift and cannot form a high beam. Therefore, it is necessary to adjust the light incident surface 421 of the high beam lens 420 with no focus shift to make it tilted. The tilt of the light incident surface can ensure that the corresponding two groups of first high beam light rays are offset in a direction close to each other instead of being diffused. Therefore, based on the above, as an example, the light entrance surface 421 and the light exit surface 422 of the high beam lens 420 with no focus shift are respectively inclined curved surfaces convex forward, and the light entrance surface 421 and the light exit surface 422 of the high beam lens 420 with no focus shift are not parallel, so that the first high beam light emitted toward the front by the two first high beam units on the left and right sides respectively is refracted twice by the corresponding inclined light entrance surface 421 and the inclined light exit surface 422 and then emitted to the side close to each other.

[0072] Specifically, the light entrance surface 421 and the light exit surface 422 of the high beam non-focus shift lens 420 designed in this example are not parallel, so that in the width direction of the optical module, the thickness dimension in the front-to-back direction between the light entrance surface and the light exit surface of the high beam non-focus shift lens 420 gradually changes (for example, Figure 6In the figure, in the width direction from the middle to the side of the outer lens 400, the thickness of the high beam lens 420 with no focus shift gradually increases in the front-to-back direction, that is, the angle between the light incident surface 421 and the front-to-back direction is smaller than the angle between the light exit surface 422 and the front-to-back direction). Only in this way can the left and right beams of first high beam light respectively incident from the front be emitted to the side close to each other after being refracted twice by the inclined light incident surface 421 and the inclined light exit surface 422, so as to achieve the offset between them. That is, the non-parallel design between the inclined light incident surface 421 and the inclined light exit surface 422 of the high beam lens 420 with no focus shift can make the first high beam light on the left and right sides offset and merge in the direction close to each other to form a high beam light pattern.

[0073] refer to Figure 2 In some embodiments, the ratio of the horizontal dimension to the vertical dimension of the outer lens 400 is greater than or equal to 4:1.

[0074] Specifically, the first high beam unit 210 is arranged side by side on the left and right sides of the low beam unit 100 in the horizontal direction. The light emitted from both sides greatly increases the area of ​​the entire high beam pattern, thereby improving the efficiency and brightness of the narrow-opening optical module, which is particularly suitable for optical modules with a large aspect ratio. According to experiments, when the aspect ratio of the outer lens 400 exceeds 4:1, the size utilization rate of the outer lens 400 can reach 100%, thereby maximizing the luminous efficiency.

[0075] refer to Figure 2 In some embodiments, the first high beam unit 210 includes a circular concentrator, the light emitting surface of the circular concentrator faces straight ahead and is opposite to the high beam zero-focus shift lens 420, and is used to collimate the first high beam light emitted straight ahead.

[0076] Specifically, the circular concentrators on both sides can converge the light emitted by the rear light source to form a first high beam light that is emitted directly in front of it, and further horizontally offset in a direction close to each other through the high beam non-focus offset lens 420 to form a circular high beam bright spot. The circular high beam light pattern is regular and the visual lighting effect is better.

[0077] refer to Figure 2 In some embodiments, the low beam unit 100 includes a plurality of low beam concentrators arranged side by side in the horizontal direction. Further, there are 7 low beam concentrators, with the middle low beam concentrator as the center, and the side low beam concentrators are arranged symmetrically. The low beam concentrators are arranged symmetrically horizontally so that the collimated light is symmetrical in the horizontal direction and the output light has a regular shape.

[0078] refer to Fig. 9In some embodiments, the second high beam unit 220 includes a plurality of high beam concentrators arranged side by side in the horizontal direction. Further, the number of high beam concentrators is 3, with the middle high beam concentrator as the center, and the side high beam concentrators are arranged symmetrically. The high beam concentrators are arranged symmetrically horizontally so that the collimated light is symmetrical in the horizontal direction, and the output light has a regular shape.

[0079] refer to Figure 3 In some embodiments, the projections of the first high beam unit 210 and the baffle 300 in a vertical plane perpendicular to the first high beam light do not overlap. That is, the two first high beam units 210 are respectively located on the left and right outer sides of the baffle 300 in the width direction, and the first high beam light collimated by the first high beam unit 210 does not pass through the baffle 300, and the light pattern formed by the combination is more regular.
