Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, and more specifically, to a headlight module and a vehicle lamp. Background Technology

[0002] In common automotive headlights, low beam and high beam are the main components. The high and low beam illumination is achieved primarily through an optical system composed of a combination of reflectors and lenses. For example, light emitted from a light source is reflected by a reflector, then passes through a lens to form the high and low beam patterns required for automotive lighting.

[0003] However, in existing automotive headlights, the high beam and low beam modules are typically presented as two separate components, or arranged vertically to form an integrated high and low beam module. These two methods occupy a significant amount of vertical space within the headlight, limiting the possibility of smaller and more diverse designs in terms of size and shape. To meet the requirements for light shape and brightness, the reflectors and lenses are quite large, resulting in overly large openings in the headlight module. This restricts the size and shape of the headlight, failing to meet the market demand for narrow-aperture light output. Summary of the Invention

[0004] The purpose of this application is to provide a headlight module and vehicle light that can save internal vertical space of the vehicle light, reduce costs, and meet the market demand for narrow-aperture light emission of vehicle lights.

[0046] Please refer to Figures 1 to 3 This application provides a headlight module 100, installed on a vehicle, including: a low beam light source 110, a high beam light source 120, a reflector 130, and a lens 140. The reflector 130 is divided into a low beam reflection area 131 and a high beam reflection area 132, which are arranged along the front-rear direction of the vehicle. The low beam light source 110 and the high beam light source 120 correspond to the low beam reflection area 131 and the high beam reflection area 132, respectively. The light emitted by the low beam light source 110 is reflected by the low beam reflection area 131 and then passes through the lens 140 and is projected onto the target plane to form a low beam pattern. The light emitted by the high beam light source 120 is reflected by the high beam reflection area 132 and then passes through the lens 140 and is projected onto the target plane to form a high beam pattern.

[0047] In the above-mentioned headlight module 100, the low beam optical component used to form the low beam pattern and the high beam optical component used to form the high beam pattern share the same lens 140, which can save costs and occupy less space, and is conducive to the miniaturization and diversification of the headlight in terms of size and shape. The low beam reflection area 131 and the high beam reflection area 132 are arranged along the front and rear directions of the vehicle, which reduces the vertical dimensions of the headlight module 100, saves vertical space inside the headlight, and can better meet the market demand for narrow opening light output of headlights.

[0048] In one embodiment, a plurality of near-light reflecting units 1311 are provided in the near-light reflecting region 131 of the reflector 130, and a plurality of far-light reflecting units 1321 are provided in the far-light reflecting region 132. The plurality of near-light reflecting units 1311 and the plurality of far-light reflecting units 1321 are respectively arranged along the left-right direction. Figure 2The lenses 140 and the low-beam reflective areas 131 and 132 are arranged sequentially along the front-to-back direction (direction A) to form a row of low-beam reflective units 1311 and a row of high-beam reflective units 1321, which are set in parallel. Figure 2 The arrangement of the low beam reflective area 131 and the high beam reflective area 132 in the B direction is not limited. It can be that the low beam reflective area 131 is in front and the high beam reflective area 132 is behind, or the high beam reflective area 132 is in front and the low beam reflective area 131 is behind.

[0049] The low beam light source 110 and the high beam light source 120 each include multiple units, with each low beam reflector unit 1311 corresponding to at least one low beam light source 110 and each high beam reflector unit 1321 corresponding to at least one high beam light source 120. Figure 2 The illustration shows an embodiment where one low beam reflector unit 1311 corresponds to one low beam light source 110, and one high beam reflector unit 1321 corresponds to one high beam light source 120. It is understood that in some other embodiments, one low beam reflector unit 1311 may also correspond to multiple low beam light sources 110, and one high beam reflector unit 1321 may also correspond to multiple high beam light sources 120.

[0050] Lens 140 includes multiple lens units 141, which are connected sequentially along the left-right direction. Please refer to the reference. Figure 4 and Figure 5 Each lens unit 141 corresponds to at least one near-beam reflector unit 1311 and at least one far-beam reflector unit 1321. Figure 4 The illustration shows an embodiment where one lens unit 141 corresponds to one near beam reflecting unit 1311 and one far beam reflecting unit 1321. Figure 5 The illustration shows an embodiment in which one lens unit 141 corresponds to one low beam reflector unit 1311 and multiple high beam reflector units 1321. It is understood that in some other embodiments, one lens unit 141 may also correspond to multiple low beam reflector units 1311 and one high beam reflector unit 1321, or one lens unit 141 may correspond to multiple low beam reflector units 1311 and multiple high beam reflector units 1321.

[0051] The light emitted by the low beam source 110 is reflected by its corresponding low beam reflector 1311, and then by its corresponding lens unit 141 to form a low beam pattern unit. Multiple low beam pattern units formed by lens units 141 are superimposed to form a low beam pattern. Similarly, the light emitted by the high beam source 120 is reflected by its corresponding high beam reflector 1321, and then by its corresponding lens unit 141 to form a high beam pattern unit. Multiple high beam pattern units formed by lens units 141 are superimposed to form a high beam pattern. Different lighting functions can be achieved by controlling the on / off states of the multiple low beam sources 110 and multiple high beam sources 120.

[0052] In one embodiment, the near beam reflecting region 131 and the far beam reflecting region 132 are arranged in a front-to-back direction. For example, as Figure 2 and Figure 3 As shown, the low beam reflection area 131 and the high beam reflection area 132 are sequentially arranged along the front-to-back direction ( Figure 2 and Figure 3 Arranged in direction B, or, as Figure 4 As shown, the high beam reflection area 132 and the low beam reflection area 131 are arranged sequentially along the front-to-back direction ( Figure 4 The low beam reflector 131 and the high beam reflector 132 are arranged in the B direction. It can be understood that the low beam reflector 131 should not obstruct the formation of the high beam pattern. The low beam reflector 131 and the high beam reflector 132 are arranged one after the other, which reduces the vertical volume of the headlight module 100, saves vertical space inside the headlight, and the low beam light source 110 and the high beam light source 120 can be set on the same circuit board 150, which helps to reduce costs.

[0053] Please refer to the reference. Figure 8 In one embodiment, a cutoff line structure 133 is provided on the first reflective surface 1311a of the low beam reflector 1311 at the boundary away from the low beam light source 110, so that the low beam pattern has a cutoff line. The high beam reflector 1321 has at least two focal points. The high beam light source 120 is located at the first focal point of the high beam reflector 1321, the cutoff line structure 133 is located at the second focal point of the high beam reflector 1321, and the focal point of the lens unit 141 is located at the cutoff line structure 133. Part of the light emitted by the high beam light source 120 is reflected by the high beam reflector 1321 and converges at the cutoff line structure 133 on the low beam reflector 1311. Then, it is emitted after passing through the cutoff line structure 133 and then through the lens 140, forming a high beam pattern with a cutoff line.

[0054] It should be noted that when light converges to the focal point, it does not necessarily mean that the light is directly on the focal point. It can also be near the focal point (<2mm). Similarly, setting the focal point at the cutoff line structure can mean both setting the focal point on the cutoff line structure and setting the focal point near the cutoff line structure.

[0055] In one embodiment, the first reflecting surface 1311a of the low beam reflecting unit 1311 is a parabolic or parabolic-like surface, an ellipsoid or an ellipsoid-like surface, and the reflecting surface of the high beam reflecting unit 1321 is an ellipsoid or an ellipsoid-like surface. A parabolic surface has one focal point, and an ellipsoidal surface has two focal points. When there are multiple low beam reflecting units 1311, the first reflecting surface 1311a of the multiple low beam reflecting units 1311 can be a parabolic surface at the same time, or a ellipsoidal surface at the same time, or a part can be a parabolic surface and the other part can be an ellipsoidal surface.

[0056] It should be noted that when the term "quasi-ellipsoidal surface" is used, it should be understood as having a surface shape that approximates an ellipsoid and possessing optical characteristics similar to those of an ellipsoid. Similarly, when the term "quasi-parabolic surface" is used, it should be understood as having a surface shape that approximates a parabola and possessing optical characteristics similar to those of a parabola. For example, a parabolic reflective surface, when used as a reflective surface, allows light rays emitted from a light source located at or near the focal point of the parabolic surface to exit in a generally parallel manner after reflection.

[0057] Please refer to Figure 9 and Figure 10 , Figure 9 for Figure 3 A schematic diagram of the low beam path of the headlight module 100. Figure 10 for Figure 3 The diagram shows the high beam path of the headlight module 100. In this embodiment, the low beam reflecting area 131 is located between the high beam reflecting area 132 and the lens 140. The first reflecting surfaces 1311a of the multiple low beam reflecting units 1311 are parabolic, and the reflecting surfaces of the multiple high beam reflecting units 1321 are ellipsoids. The low beam light source 110 is located at the focal point of the parabolic surface, the high beam light source 120 is located at the first focal point of the ellipsoid, and the cutoff line structure 133 on the low beam reflecting unit 1311 is located at the second focal point of the ellipsoid. The light emitted by the low beam light source 110 is reflected by the parabolic surface and becomes parallel light that travels towards the lens 140. The light emitted by the high beam light source 120 is reflected by the ellipsoid and converges at the cutoff line structure 133, and then travels towards the lens 140 via the cutoff line structure 133.

[0058] Please refer to Figure 3 In one embodiment, the surface of the low beam reflecting unit 1311 facing the high beam reflecting unit 1321 is a second reflecting surface 1311b. Part of the light emitted by the high beam light source 120 is reflected sequentially by the reflecting surface of the high beam reflecting unit 1321 and the second reflecting surface 1311b, and then projected onto the target plane as a high beam pattern through the lens 140. The second reflecting surface 1311b can project part of the light that would originally be projected below the light-dark cutoff line onto the upper part of the high beam pattern to increase the high beam illuminance value.

[0059] like Figures 11 to 13 As shown, Figure 11 This is a schematic diagram of the far and near beam patterns of a single unit. Figure 12 This is a schematic diagram of the near-beam shape of a single unit. Figure 13 This is a schematic diagram of the high beam pattern of a single unit. The low beam and high beam lighting patterns are achieved by superimposing multiple units to form beam patterns.

[0060] Please refer to Figure 4 and Figure 5 In one embodiment, the high beam reflecting area 132 and the low beam reflecting area 131 are arranged sequentially along a front-to-back horizontal direction, that is, the high beam reflecting area 132 is located between the low beam reflecting area 131 and the lens 140. It is understood that the high beam reflecting area 132 should not obstruct the formation of the low beam pattern. The front-to-back distribution of the low beam reflecting area 131 and the high beam reflecting area 132 reduces the vertical volume of the headlight module 100, saving internal vertical space in the headlight. Furthermore, the low beam light source 110 and the high beam light source 120 can be housed on the same circuit board 150, which helps reduce costs.

[0061] In one embodiment, a cutoff line structure 133 is provided on the reflective surface of the high beam reflecting unit 1321 at the boundary away from the high beam light source 120, so that the high beam pattern has a cutoff line. The low beam reflecting unit 1311 has at least two focal points. The low beam light source 110 is located at the first focal point of the low beam reflecting unit 1311, and the cutoff line structure 133 is located at the second focal point of the low beam reflecting unit 1311. The focal point of the lens unit 141 is located at the cutoff line structure 133. The light emitted by the low beam light source 110 is reflected by the low beam reflecting unit 1311 and converges at the cutoff line structure 133 on the high beam reflecting unit 1321. Then, it is emitted after passing through the cutoff line structure 133 and then through the lens 140, forming a low beam pattern with a cutoff line.

[0062] Please refer to Figure 5 In one embodiment, the surface of the high beam reflecting unit 1321 facing the low beam reflecting unit 1311 is a third reflecting surface 1321b. Part of the light emitted by the low beam light source 110 is reflected sequentially by the reflecting surface of the low beam reflecting unit 1311 and the third reflecting surface 1321b, and then projected onto the target plane as a low beam pattern through the lens 140. The third reflecting surface 1321b can project part of the light that would originally be projected above the light-dark cutoff line to the lower part of the low beam pattern to improve the low beam illuminance value.

[0063] In one embodiment, the reflecting surface of the high beam reflecting unit 1321 is a parabola, a parabolic-like surface, an ellipsoid, or an ellipsoid, and the reflecting surface of the low beam reflecting unit 1311 is an ellipsoid or an ellipsoid. A parabolic surface has one focal point, and an ellipsoidal surface has two focal points. When multiple high beam reflecting units 1321 are included, the reflecting surfaces of the multiple high beam reflecting units 1321 can all be parabolic, or all be ellipsoidal, or some can be parabolic and others ellipsoidal.

[0064] Please refer to Figure 6 and Figure 7 In one embodiment, the low beam reflector 1311 and at least one high beam reflector 1321 are aligned in the vertical direction ( Figure 7 The low beam reflector unit 1311 and the high beam reflector unit 1321 are arranged in the C direction, which is perpendicular to the A and B directions respectively. That is, the low beam reflector unit 1311 and the high beam reflector unit 1321 are distributed vertically, and the vertically arranged low beam reflector unit 1311 and high beam reflector unit 1321 can be integrally formed. This arrangement can save the left and right space inside the headlight.

[0065] Please refer to Figure 2 In one embodiment, the lens 140 includes a plurality of lens units 141 connected in the left-right direction. The light-emitting surface of the lens unit 141 is a curved surface stretched in the left-right direction to collimate the light in the up-down direction. The light-incident surface 142 of the lens unit 141 can be a curved surface stretched in the up-down direction or a stretched curved surface in a direction having an angle with the up-down direction to collimate the light in the left-right direction or to collimate the light in a direction perpendicular to the stretching direction.

[0066] For details, please refer to Figure 14 With the light-emitting surface of the lens unit 141 determined, the angle of the light-incident surface 142 of the lens unit relative to the horizontal plane is changed so that the focal point of each lens unit 141 is located at a different position. That is, the focal point of the lens unit 141 is not always located at the light-dark cutoff line structure 133, thereby avoiding the appearance of dark areas in the light pattern obtained after the light pattern units formed by the light emitted from the lens unit 141 are superimposed.

[0067] Please refer to Figure 2 and Figure 4In one embodiment, the headlight module 100 further includes a circuit board 150, on which multiple low beam light sources 110 and multiple high beam light sources 120 are disposed. The multiple low beam light sources 110 and multiple high beam light sources 120 are arranged sequentially along the left-right horizontal direction on the circuit board 150 to correspond to the positions of the low beam reflector unit 1311 and the high beam reflector unit 1321. The circuit board 150 can control the on / off state of individual low beam light sources 110 and individual high beam light sources 120, thereby achieving different lighting functions. The multiple low beam light sources 110 and multiple high beam light sources 120 mounted on the same circuit board 150 occupy less space, are easier to control, and can save costs, which is beneficial for achieving more miniaturized and diversified designs in terms of size and shape of the vehicle lights.
