[0001] The present invention relates to a vehicle lamp capable of emitting a light distribution pattern for passing. [Background technology]

[0002] There are vehicle lamps that form light distribution that takes pedestrians into consideration (for example, Patent Document 1). In order not to dazzle pedestrians, light is not directed at the heads of pedestrians. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2018-206686 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, a light distribution pattern is formed so that the light is not directed at the heads of pedestrians. However, when the light is directed at the pedestrians by passing the lights, if the light does not reach the pedestrians' heads, the pedestrians may not notice the vehicle. This is putting the cart before the horse, so when the light is passed, it is desirable to direct the light in a way that takes the pedestrians' attention into consideration and does not dazzle them. In addition, Patent Document 1 is a lamp with variable light distribution control, and the lamp has a complex configuration, so it is desirable to implement it with a simpler configuration.

[0005] The present invention has been made in view of the above, and provides a vehicle lamp capable of forming a passing light distribution pattern that takes pedestrians into consideration with a simple configuration. [Means for solving the problem]

[0007] In one embodiment, the light distribution pattern for passing is formed by irradiating a second light distribution pattern above the light distribution pattern for high beam, the second light distribution pattern being dimmed more than the light distribution pattern for high beam.

[0008] In one embodiment, the passing light distribution pattern is formed by dimming an upper region of the high beam light distribution pattern.

[0009] In one embodiment, the vehicle includes a high beam lamp unit capable of emitting the high beam light distribution pattern, and a passing lamp unit capable of emitting the passing light distribution pattern.

[0010] In one aspect, the passing lamp unit has a light source, an optical element that receives light from the light source and irradiates the light by forming a predetermined light distribution pattern, and a reflecting element that receives a portion of the light emitted by the light source and reflects it toward the optical element, and the optical element is configured to form and irradiate the dimming area with the light reflected by the reflecting element.

[0011] In one aspect, the passing lamp unit has a light source and an optical element that receives light from the light source and irradiates the light by forming a predetermined light distribution pattern, and a portion of the optical element is configured to receive a portion of the light emitted by the light source and diffuse it to form the dimming area and irradiate the light.

[0012] In one embodiment, the lamp has a first light source, a second light source, and an optical element that irradiates light emitted from the first light source and the second light source forward to form a desired light distribution pattern, and is configured so that the high beam light distribution pattern or the passing light distribution pattern is formed and irradiated by the optical element when the first light source or the second light source is turned on or off.

[0015] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The embodiments are illustrative and do not limit the invention, and all features and combinations described in the embodiments are not necessarily essential to the invention. In the following description of the embodiments and modifications, the same components are given the same reference numerals, and duplicated descriptions are omitted as appropriate.

[0016] (First embodiment) FIG 1 is a front view showing a schematic configuration of a vehicle lamp 1 according to a first embodiment. The vehicle lamp 1 is a headlamp mounted on the left and right corners of the front of a vehicle. The vehicle lamps 1 are provided in a pair on the left and right, and are configured symmetrically to each other. The following description focuses on the vehicle lamp 1 mounted on the left side.

[0017] The vehicle lamp 1 comprises, as a lamp housing, a lamp body 2 and a lamp cover 4. The lamp body 2 is open at the front, and the lamp cover 4 made of a translucent resin is attached to the opening, defining a lamp chamber S inside.

[0018] The vehicle lamp 1 accommodates three lamp units LU1 to LU3 in a lamp chamber S. Each of the lamp units LU1 to LU3 includes a light source that is a light-emitting element, and forms light emitted from the light source into a predetermined lamp light distribution and emits it forward of the vehicle.

[0019] The first lamp unit LU1 is a low beam lamp unit, and the second lamp unit LU2 is a high beam lamp unit. The first lamp unit LU1 and the second lamp unit LU2 form a low beam light distribution / high beam light distribution alone or in cooperation with each other, and irradiate the light in front of the vehicle.

[0020] The third lamp unit LU3 is a lamp unit for passing. The third lamp unit LU3 forms a passing light distribution in cooperation with the first lamp unit LU1 and the second lamp unit LU2 or independently, and irradiates the vehicle front. Generally, high beam light distribution or low beam light distribution is used for passing, but in this embodiment, the passing light distribution is configured as a light distribution different from the high beam light distribution / low beam light distribution.

[0021] The three lamp units LU1 to LU3 are controlled to be turned on and off by a switch SW. The low beam light distribution and high beam light distribution can be switched on and off automatically or manually. The passing light distribution is formed for a short period of time by the driver manually inputting the switch SW. When a passing command is input, the third lamp unit LU3 is turned on for a short period of time, forming a passing light distribution in front of the vehicle. Passing is primarily used as a form of communication, such as to alert or signal drivers and pedestrians in the oncoming position of the vehicle. For this reason, the passing light distribution is manually input at the driver's discretion.

[0022] (Passing lamp unit) The configuration of the lamp unit LU will be described. The first lamp unit LU1 and the second lamp unit LU2 may be optical units of a conventionally known configuration such as a reflector type or a projector type, as long as they can form a low beam light distribution / high beam light distribution, and the type does not matter. The first lamp unit LU1 and the second lamp unit LU2 may have different configurations. They may be devices capable of forming an arbitrary pattern in light, such as a DMD (Digital Mirror Device), pixel optical devices such as an LED array or a liquid crystal shutter, or drawing units such as a scanning device that scans laser light at high speed to form an image by an afterimage, or a single lamp unit that integrates both lamp units may be used.

[0023] 2 is a vertical cross-sectional view showing a schematic configuration of the third lamp unit LU3. As shown in FIG. 2, the third lamp unit LU3 includes a reflector 11, a light source 12 which is a light-emitting element, and a dimming plate 13, all of which are attached to and supported by a support member 14.

[0024] The light source 12 is a semiconductor light emitting element such as an LED (Light Emitting Diode), an LD (Laser Diode), or an EL (Electro Luminescence) element.

[0025] The light-reducing plate 13 is a reflector configured to receive a portion of the light emitted from the light source 12 and guide at least a portion of the incident light to the reflector 11. The light-reducing plate 13 is configured not to collect the incident light, but rather to diffuse / diminish the light and guide it to the reflector 11. For this reason, the inner surface 13a of the light-reducing plate 13 is a reflective surface for the light emitted from the light source 12, but is configured to reduce the incidence rate of light into the reflector 11. For example, the inner surface 13a is matte-finished, a dimming film is attached to the inner surface 13a, the inner surface 13a is coated with anti-reflective paint, the light-reducing plate 13 is made of a light-absorbing material, or the light is mainly diffused toward other than the reflector 11. The light-reducing plate 13 is processed to reflect light with less light than the incident light. The light reducing plate 13 ensures that the light L1 emitted from the light source 12, reflected by the light reducing plate 13 and incident on the reflector 11 has a lower luminous intensity than the light L2 that is incident on the reflector 11 directly from the light source 12.

[0026] The reflector 11 is an optical member configured to receive the light emitted from the light source 12, reflect it, and guide it to the front of the lamp unit, and its inner surface is a predetermined reflecting surface 11a. The light emitted from the light source 12 and incident on the reflector 11 includes not only the light L2 directly incident from the light source 12, but also the light L1 incident on the light-reducing plate 13 and reflected toward the reflector 11.

[0027] The reflector 11 is a step reflector that is a step-shaped reflector divided into a plurality of reflecting elements. After molding, the inner surface of the reflector 11 is subjected to metal deposition to form a reflecting surface 111a.

[0028] The support member 14 is a flat plate, and the light source 12 is attached to the support member 14 with its light-emitting surface facing vertically downward. The reflector 11 is configured to have a substantially radial cross-sectional shape, and is disposed with its upper end fixed to the support member 14 and its reflective surface 11a facing forward. The light-reducing plate 13 is disposed in front of the light source 12 with its upper end fixed to the support member 14 and its inner surface 13a facing the light source 12 and the reflector 11. The light-reducing plate 13 is smaller than the reflector 11, and a portion of the light emitted from the light source 12 enters the light-reducing plate 13 and is reflected to the reflector 11.

[0029] (Light distribution pattern of the first embodiment) 3 is a schematic diagram showing the illumination range of each lamp unit formed on a virtual vertical screen located 25 m ahead of the vehicle by the light emitted from the vehicle lamp 1. It also shows a schematic diagram of the light distribution pattern formed by the vehicle lamp 1. The axial centers of the horizontal line (HH line) and vertical line (VV line) on the virtual vertical screen pass through the optical axis of the vehicle lamp 1.

[0030] As shown in FIG. 3A, the first lamp unit LU1, which is a low beam lamp unit, forms light from a light source into a low beam light distribution pattern P1 having a cutoff line CL, and irradiates the light in front of the vehicle.

[0031] The second lamp unit LU2, which is a lamp unit for high beam, forms a light distribution pattern for high beam P2 above the light distribution pattern for low beam P1. The light distribution pattern for high beam P2 is mainly formed slightly above the horizontal line (HH line).

[0032] 3B, the third lamp unit LU3, which is a lamp unit for passing, forms a light distribution pattern for passing P3 in front of the vehicle. The outer shape of the light distribution pattern for passing P3 is substantially the same as the light distribution pattern for high beam P2.

[0033] The reflector 11 forms the light from the light source 12 into a passing light distribution pattern P3 and emits it forward of the vehicle. The dimming plate 13 is disposed forward of the light source 12, and of the light incident on the reflector 11, the light L1 reflected by the dimming plate 13 is reflected slightly upwards compared to the light L2 directly incident from the light source 12.

[0034] Therefore, the light distribution pattern P3 for passing is divided into an upper region formed by the light L1 and a lower region formed by the light L2, and the light distribution pattern P3 for passing is formed by combining the two regions.

[0035] The light L1 emitted from the light source 12, reflected by the light-reducing plate 13, and incident on the reflector 11 has a lower luminous intensity than the light L2 emitted from the light source 12 and directly incident on the reflector 11. For this reason, the upper region of the light distribution pattern for passing lights P3 is a "dimming region" having a lower luminous intensity than the lower region. Hereinafter, the upper region formed by the light L1 is referred to as the dimming region P31, and the lower region formed by the light L2 is referred to as the normal region P32. The upper region of the light distribution pattern for passing lights P3 is the dimming region P31, and the lower region is the normal region P32, and both regions are separated into upper and lower regions by the boundary line LN.

[0036] Fig. 4 is a side view illustrating the upper and lower illumination ranges of the vehicle lamp 1. In Fig. 4, the range of light illuminated by the vehicle lamp 1 is indicated by light ink. The darker the light ink, the higher the luminous intensity.

[0037] As an example, if the distance to a pedestrian walking in front of the vehicle is L=8 m, the pedestrian's height T=1.7 m, the pedestrian's head length Hd=0.3 m, and the mounting height of the vehicle lamp 1 is Hl=0.9 m, The height from the vehicle lamp 1 to the bottom of the pedestrian's head Hh = T-Hl-Hd = 0.5 m Linear distance R from vehicle lamp 1 to the bottom of the pedestrian's head =(L 2 +HH 2 ) 0.5 =8.015m The illumination angle of the normal region P32, that is, the set angle θ of the boundary line LN based on the installation position of the vehicle lamp 1 =arcsin(HH / R)=arcsin(0.5 / 8.015)=3.57°

[0038] In this embodiment, the passing light distribution is a dimmed area P31 in which the upper area is dimmed, and the boundary line LN is set so that the low-luminance dimmed area P31 generally hits the head of a pedestrian in front of the vehicle.

[0039] The boundary line LN is an upper illumination boundary of the normal region P32, and the set angle θ of the boundary line LN (i.e., the upward illumination angle of the normal region P32) based on the installation position (horizon HH) of the vehicle lamp 1 is preferably 4° or less. In this embodiment, the lamp unit that forms the high beam light distribution and the lamp unit that forms the passing light distribution are different, and the high beam light distribution and the passing light distribution are switched by the lamp unit itself, so that in consideration of the installation margin, it is preferable that the normal region P32 is located slightly lower than the ideal position, and the set angle θ of the boundary line LN is preferably 2.8° to 4°.

[0040] Passing is a signal to pedestrians and drivers in front of the vehicle. Generally, passing is performed by turning on high beams for a short period of time, but if the high beams are directly directed at a pedestrian for only a short period of time, there is a risk of dazzling the pedestrian as if a flash had been turned on. However, if no light hits the pedestrian's head, the pedestrian or driver may not notice you. For this reason, when passing, it is desirable to use light that is designed to attract the attention of the other party without dazzling them. In this embodiment, a dimmed light-reducing area is provided in the upper area that hits the pedestrian's head in the passing light distribution, and the passing light distribution is irradiated for only a short time when the vehicle is passing, so that the pedestrian is not dazzled and the attention of the pedestrian is attracted. Unlike an adjustable light distribution lamp (ADB), a complex mechanism is not required, and the passing light distribution is irradiated for a short time only when the driver manually inputs the passing light, so that neither sensors nor complex control are required, and the effect can be obtained with a simple configuration.

[0041] (Modification) 5 shows a third lamp unit LU3' which is a modified example of the third lamp unit LU3 which is a lamp unit for passing. The third lamp unit LU3' includes a light source 12, a reflector 11', and a support member 14, and is configured to form light emitted from the light source 12 into a light distribution pattern for passing P3 and emit the light in front of the vehicle. The third lamp unit LU3' does not include the light-reducing plate 13, and has the same configuration as the third lamp unit LU3 except for the configuration of the reflector 11'.

[0042] The reflector 11' is configured to receive the light emitted from the light source 12, reflect it, and guide it forward of the lamp unit, and the inner surface is a predetermined reflecting surface 11a'. The reflector 11' is composed of an upper part 11b close to the light source 12, and a lower part 11c below the upper part 11b. The upper part 11b is configured to reflect the incident light L4 to mainly form the normal area P32 of the passing light distribution pattern P3, and the lower part 11c is configured to reflect the incident light L3 to mainly form the dimming area P31. For example, the lower part 11c is configured to form the dimming area P31 by diffusing the incident light over a wide range to reduce the luminous intensity, by dulling the reflecting surface 11a so that the reflectance of the lower part 11c is lower than that of the upper part 11b, or by adjusting the direction of reflection.

[0043] Thereby, the third lamp unit LU3' can form a passing light distribution pattern P3 having a dimming region P31 in the upper region in the same manner as the third lamp unit LU3.

[0044] Second embodiment 6 is a front view of a vehicle lamp 101 according to the second embodiment. The vehicle lamp 101 accommodates a first lamp unit LU1 and a fourth lamp unit LU4 in a lamp chamber S. The first lamp unit LU1 is capable of forming a low beam light distribution and is the same as in the first embodiment, so a description thereof will be omitted.

[0045] The fourth lamp unit LU4 combines the functions of the second lamp unit LU2 and the third lamp unit LU3. That is, the fourth lamp unit LU4 can form and irradiate high beam and passing light distributions from the light of the light source, and can also switch between the two light distributions.

[0046] As with the vehicle lamp 1, the two lamp units LU1 and LU4 are controlled to be turned on and off by the switch SW. The passing light distribution of the fourth lamp unit LU4 is irradiated for a short period of time by the driver manually operating the switch SW.

[0047] (High beam and passing lamp unit) The configuration of the fourth lamp unit LU4 will be described in detail. Fig. 7 is a vertical cross-sectional view of the fourth lamp unit LU4. As shown in Fig. 7, the fourth lamp unit LU4 includes a reflector 111, a first light source 115 and a second light source 116, which are two light-emitting elements, and a support member 114 to which these are attached.

[0048] The first light source 115 and the second light source 116 are semiconductor light emitting elements like the light source 12, and are attached to a flat support member 114 with their light emitting surfaces facing vertically downward. The first light source 115 and the second light source 116 are arranged side by side in the front-to-rear direction, and the first light source 115 is arranged in front of the second light source 116.

[0049] The reflector 111 is configured to receive and reflect the light L5 emitted from the first light source 115 and the light L6 emitted from the second light source 116 to form a predetermined light distribution and guide it to the front of the lamp unit, and its inner surface is a predetermined reflecting surface 111a. Similar to the reflector 11 of the first embodiment, it is configured to have a radial cross-sectional shape, has an upper end fixed to the support member 114, and is disposed with the reflecting surface 111a facing forward.

[0050] The fourth lamp unit LU4 functions as both a high beam lamp unit and a passing lamp unit, and in this embodiment, the light distribution it forms is switched by turning on and off each light source. Specifically, when emitting a high beam light distribution, only the second light source 116 is turned on. When emitting a passing light distribution, the first light source 115 is turned on for only a short time. The first light source 115 has a lower luminance than the second light source 116, and the light L5 emitted by the first light source 115 has a lower luminous intensity than the light L6 emitted by the second light source 116.

[0051] (Light distribution pattern of the second embodiment) Fig. 8 is a schematic diagram showing the illumination range of each lamp unit formed on a virtual vertical screen located 25 m ahead of the vehicle by the light emitted from the vehicle lamp 101. It is a schematic diagram showing the light distribution pattern formed by the vehicle lamp 101. The axial centers of the horizontal line (HH line) and vertical line (VV line) on the virtual vertical screen pass through the optical axis of the vehicle lamp 101. Fig. 8 corresponds to Fig. 3.

[0052] As shown in FIG. 8(A), the first lamp unit LU1, which is a lamp unit for low beam, forms light from a light source into a light distribution pattern P1 for low beam having a cutoff line CL, and irradiates the light ahead of the vehicle.

[0053] Next, the fourth lamp unit LU4 turns on the second light source 116 to form a high beam light distribution pattern P42. The high beam light distribution pattern P42 overlaps a lower region of the low beam light distribution pattern P1 and is formed mainly slightly above the horizontal line (HH line).

[0054] 8(B), when the first light source 115 of the fourth lamp unit LU4 is turned on, a passing light distribution pattern P41 is formed. The high beam light distribution pattern P42 is formed above the low beam light distribution pattern P1, with a partial area overlapping the low beam light distribution pattern P1. Since the passing light distribution pattern P41 is formed by the light L5 emitted from the first light source 115, it is a dimming area with a lower luminous intensity than the high beam light distribution pattern P42 formed by the light L6 emitted from the second light source 116.

[0055] As described above, the passing light distribution is configured so that the dimming region in the upper region hits the head of a pedestrian in front of the vehicle. When passing the lights, the first light source 115 is turned on for a short time to form the passing light distribution pattern P41, making it possible to send a signal to pedestrians without dazzling them.

[0056] The upper end of the high beam light distribution pattern P42 is set as the boundary line LN2. The passing light distribution pattern P41 is irradiated beyond the substantially horizontal boundary line LN2, but the high beam light distribution pattern P42 is configured not to irradiate beyond the horizontal boundary line LN2. The boundary line LN2 is an upper irradiation boundary of the high beam light distribution pattern P42, and the upper irradiation angle of the light L8 is set as the set angle θ2 of the boundary line LN2. In this embodiment, the lamp units forming the high beam light distribution and the passing light distribution are the same, so it is easier to set the boundary line LN2 to a desired angle and the margin can be reduced compared to the first embodiment. In addition, it is preferable that the high beam light distribution is irradiated over as wide an area as possible, since this increases the visibility in front of the vehicle. For this reason, it is preferable that the set angle θ2 of the boundary line LN2 is 3.5° to 4°.

[0057] (Variation 2) 9 shows a fifth lamp unit LU5 which is another embodiment of the fourth lamp unit LU4 which is a high beam lamp unit and a passing lamp unit. The fifth lamp unit LU5 includes a reflector 211, a light source 212, a dimming plate 213, an actuator 217, and a support member 214.

[0058] The actuator 217 is a drive mechanism for changing the position of the dimming plate 213. The fifth lamp unit LU5 has the same configuration as the third lamp unit LU3, except that the position of the dimming plate 213 is changed by the actuator 217, and the configuration of the reflector 211. Therefore, explanations of components other than the actuator 217 will be omitted.

[0059] The actuator 217 positions / releases the dimming plate 213 in / from the optical path of the light source 212. By switching the position of the dimming plate 213, the light distribution formed in front of the vehicle by the fifth lamp unit LU5 is switched to a high beam distribution / passing light distribution.

[0060] Specifically, when the dimming plate 213 is placed in the optical path of the light source 212, the fifth lamp unit LU5 has a configuration equivalent to the third lamp unit LU3. The reflector 211 receives light L8 directly incident from the light source 212 and light L7 dimmed and reflected by the dimming plate 213, and reflects them forward to form a passing light distribution. When the dimming plate 213 moves out of the optical path of the light source 212 (dimming plate 213' in two-dot chain line), the reflector 211 receives all the light from the light source 212 directly, and reflects it forward to form a high beam light distribution.

[0061] Normally, the dimming plate 213 is in a raised state (dimming plate 213' indicated by a two-dot chain line) and is disposed outside the optical path of the light source 212. When a passing command is input from the switch SW, the actuator 217 rotates and the dimming plate 213 is disposed on the optical path of the light source 212. When the light source 212 is turned off after being turned on for a short period of time, the actuator 217 rotates in the opposite direction and the dimming plate 213 returns to its original position.

[0062] Fig. 10 is a diagram showing a typical illumination range of the fifth lamp unit LU5, and a typical light distribution pattern formed by the vehicle lamp 101. Fig. 10 corresponds to Figs. 3 and 8.

[0063] As shown in FIG. 10(A), when the light-reducing plate 113 is raised (light-reducing plate 113′ indicated by a two-dot chain line), the fifth lamp unit LU5 forms a high beam light distribution pattern P52 from all the light emitted from the light source 212.

[0064] When the driver manually inputs a command for passing from the switch SW, the actuator 217 rotates to lower the dimming plate 213, and a portion of the light from the light source 212 enters the dimming plate 213. The light L7 that enters the dimming plate 213, is dimmed, and exits the plate 213 forms a dimming region P511. The dimming region P511 and the normal region P512 form a light distribution pattern for passing P51.

[0065] A light-attenuating region P511 is formed by attenuating a portion of the light from the light source 212 by an amount corresponding to the amount of light incident on the light-attenuating plate 213. That is, the light distribution pattern for passing P51 is formed by attenuating an upper region of the light distribution pattern for high beam P52. A boundary line LN3 between the dimming region P511 and the normal region P512 is equivalent to that of the fourth lamp unit LU4, and a set angle θ of the boundary line LN3 is preferably 4° or less.

[0066] The above describes preferred embodiments of the present invention. However, the above embodiments are merely examples of the present invention, and these can be combined based on the knowledge of those skilled in the art, and such forms are also included in the scope of the present invention.
