[0002] Generally, a vehicle has a plurality of lamps including a lighting function for making it easier to identify objects around the vehicle when the vehicle is traveling at night and a signaling function for notifying surrounding vehicles or pedestrians of the vehicle's traveling status.
[0003] For example, headlights and fog lights are mainly intended for lighting, while turn signals, taillights and brake lights are mainly intended for signaling. The setting criteria and specifications of each lamp have been stipulated through laws and regulations so that their respective functions can be fully utilized.
[0004] In addition, although vehicle lamps are only units for performing lighting and signal functions, the proportion of lamps in design has recently increased. For this reason, it is necessary to improve the aesthetic sense felt by consumers by improving not only the appearance design formed by vehicle lamps when the vehicle is driving at night, but also the appearance design formed by vehicle lamps when the vehicle is driving during the day.

[0012] The first reflective portion and the second reflective portion may have different reflectivities from each other.
[0013] The second reflective portion may have a lower reflectivity than the first reflective portion.
[0014] The first reflecting portion may have a constant reflectivity according to a wavelength band of light.
[0015] The second reflection portion may have reflectances different from each other according to wavelength bands of light.

[0042] Hereinafter, the present invention will be described based on the embodiments of the present invention by referring to the accompanying drawings for describing a vehicle lamp.
[0043] Figure 1 and Figure 2 is a perspective view showing a vehicle lamp according to an embodiment of the present invention, Figure 3 1 is a side view showing a vehicle lamp according to an embodiment of the present invention.
[0044] Reference Figures 1 to 3 The vehicle lamp 1 according to the embodiment of the present invention may include a light source portion 1000 , an optical path adjustment portion 2000 , and an optical portion 3000 .
[0045] The vehicle lamp 1 of the present invention is explained using the following situation as an example: when a vehicle is traveling at night or in a dark place such as a tunnel, the headlamp is used to irradiate light in the direction of travel of the vehicle to ensure the vehicle's forward field of vision, but it is not limited to this. The vehicle lamp 1 according to the present invention can be used not only as a headlamp, but also as various lamps arranged in the vehicle such as taillights, brake lights, daytime running lights, fog lights, turn signal lights, backup lights, etc.
[0046] When the vehicle lamp 1 of the present invention is used as a headlamp, at least one of a low beam pattern and a high beam pattern can be formed. The low beam pattern irradiates light downward with a cutoff line of a predetermined shape as a reference to prevent dazzling the driver of a preceding vehicle such as a preceding vehicle or an oncoming vehicle, and ensures a wide field of view at a short distance in front of the vehicle. The high beam pattern irradiates light relatively upward compared to the low beam pattern to ensure a long field of view at a long distance in front of the vehicle.
[0047] In the following embodiments of the present invention, Figure 4As shown, a case where a low beam pattern P having a cutoff line CL of a predetermined shape is formed by the vehicle lamp 1 of the present invention is used as an example for explanation, and the low beam pattern P may include: a high illumination area P1, which has a relatively high brightness to improve the field of view distance; and an extended area P2, which has a relatively lower brightness than the high illumination area P1 to ensure a wide field of view in front of the vehicle, and is formed to expand in at least one direction of the up and down directions and the left and right directions based on the high illumination area P1.
[0048] Furthermore, in the embodiment of the present invention, the following case is used as an example for description: the X-axis direction is the left-right direction, indicating the vehicle width direction, the Y-axis direction is the front-back direction, indicating the driving direction, and the Z-axis direction is the up-down direction, indicating the vehicle height direction.
[0049] The light source unit 1000 may include at least one light source that generates light of a quantity or color suitable for the purpose of the vehicle lamp 1 of the present invention. In an embodiment of the present invention, a case where a semiconductor light-emitting element such as a light-emitting diode (LED: Light Emitting Diode) is used as at least one light source is described as an example, but it is not limited to this. Not only LEDs but also various types of light sources such as laser diodes (LD: Laser Diode) or light bulbs can be used for the at least one light source, and optical elements such as reflectors, phosphors, mirrors, etc. can be additionally used depending on the type of light source.
[0050] The optical path adjustment unit 2000 can be located in front of the light source unit 1000, and plays the role of focusing the light generated from the light source unit 1000 within a predetermined light irradiation angle range by converting it into parallel light that is approximately parallel to the optical axis Ax and travels, with the optical axis Ax passing vertically through the center of the light-emitting area of the light source unit 1000 as a reference. The optical path adjustment unit 2000 can make the light generated from the light source unit 1000 uniformly incident on the optical unit 3000 as a whole, thereby playing the role of making the light beam pattern formed by the vehicle lamp 1 of the present invention have an overall uniform brightness.
[0051] In an embodiment of the present invention, the case of using an aspheric lens as the optical path adjustment unit 2000 is described as an example, but it is not limited to this. The optical path adjustment unit 2000 can not only use an aspheric lens, but also can use various types of lenses such as a Fresnel lens or a total internal reflection (TIR: Total Internal Reflection) lens that converts the light generated from the light source unit 1100 into parallel light.
[0052] The optical portion 3000 may emit at least a portion of the light incident from the light source portion 1000 , thereby playing a role of forming a beam pattern suitable for the vehicle lamp 1 according to the present invention.
[0053] Figure 5 and Figure 6 is an exploded perspective view showing an optical part according to an embodiment of the present invention, Figure 7 is a cross-sectional view showing an optical portion according to an embodiment of the present invention.
[0054] Reference Figures 5 to 7 , the optical part 3000 according to an embodiment of the present invention may include an incident part 3100 and an emitting part 3200 .
[0055] The incident portion 3100 may include a plurality of incident lenses 3110 and a first light transmitting portion 3120, and the emission portion 3200 may include a plurality of emission lenses 3210 and a second light transmitting portion 3220. In an embodiment of the present invention, a case where miniaturization is achieved by using microlenses having a relatively short focal length as the plurality of incident lenses 3110 and the plurality of emission lenses 3210 is used as an example for explanation.
[0056] A plurality of incident lenses 3110 may be arranged on the incident surface 3121 of the first light transmission portion 3120, and a plurality of exit lenses 3210 may be arranged on the exit surface 3222 of the second light transmission portion 3220. In this case, the exit surface 3122 of the first light transmission portion 3120 and the incident surface 3221 of the second light transmission portion 3220 may be disposed in contact with or adjacent to each other in a manner opposite to each other, so that light incident on the plurality of incident lenses 3110 may be guided to the plurality of exit lenses 3210 through the first light transmission portion 3120 and the second light transmission portion 3220 and exit.
[0057] At least one shielding portion 3300 , 3400 may be provided between the plurality of incident lenses 3110 and the plurality of emission lenses 3210 to block a portion of light incident on each of the plurality of incident lenses 3110 and traveling to a corresponding emission lens among the plurality of emission lenses 3210 .
[0058] In the embodiment of the present invention, the following case is taken as an example for description: at least one shielding part 3300 , 3400 may include: a main shielding part 3300 located between the incident part 3100 and the emitting part 3200 ; and an additional shielding part 3400 located in front of the main shielding part 3300 .
[0059] The main shielding part 3300 may include a plurality of main shielding members 3310 located at or near the rear focus F of each of the plurality of emission lenses 3210, and the upper end center portion of each of the plurality of main shielding members 3310 is located at or near the rear focus F of the corresponding emission lens in the plurality of emission lenses 3210, thereby forming a Figure 4 The low beam beam pattern P with the cut-off line CL is shown.
[0060] That is, with the rear focus F of each of the multiple emission lenses 3210 as a reference, the light that travels through the lower space and is emitted can be refracted relatively toward the upper side. As a result, glare may be generated because the light may illuminate the upper side of the cut-off line. Therefore, with the rear focus F of each of the multiple emission lenses 3210 as a reference, the light that travels through the lower space is blocked by the multiple main shielding members 3310.
[0061] At this time, according to the shape of the area where light is concentrated, the rear focus F of each of the plurality of emission lenses 3210 may have the shape of a point, a line, a plane, a space, or a combination thereof.
[0062] Furthermore, in the embodiment of the present invention, the case where the upper ends of the plurality of main shielding members 3310 are horizontal is described as an example, but this is because the vehicle lamp 1 of the present invention is formed as follows. Figure 4 The cutoff line CL is a horizontal line shape as shown, but is not limited to this. According to the cutoff line shape of the low beam pattern formed by the vehicle lamp 1 of the present invention, a step difference can be formed so that a part and another part of the upper ends of the multiple main shielding parts 3310 have different heights from each other.
[0063] The additional shielding part 3400 may include a plurality of additional shields 3410 located in front of corresponding main shields among the plurality of main shields 3310 .
[0064] The multiple additional shielding members 3410 can prevent light incident on each of the multiple incident lenses 3110 from being incident on the corresponding output lens and other adjacent output lenses in the multiple output lenses 3210, thereby preventing light from being irradiated to unnecessary directions.
[0065] That is, when light incident on each of the multiple incident lenses 3110 is emitted through the corresponding emission lens among the multiple emission lenses 3210, it can be emitted approximately parallel to the optical axis Ax, but when incident on other emission lenses adjacent to the corresponding emission lens, the light is emitted due to refraction toward the upper side or the lower side, and thus may be irradiated in unnecessary directions. As a result, glare may be generated due to the light being irradiated to the upper side of the cutoff line of the low beam pattern. Therefore, multiple additional shielding members 3410 can be used to prevent the light from being irradiated in unnecessary directions.
[0066] Furthermore, the plurality of additional shields 3410 may block light incident on the lower end portion of each of the plurality of output lenses 3210 , because the light irradiated to the upper side of the cutoff line of the low beam pattern to produce glare is mainly light incident on the lower end portion of each of the plurality of output lenses 3210 .
[0067] The upper end of each of the multiple additional shielding members 3410 can be located at a lower position than the upper end of the corresponding main shielding member among the multiple main shielding members 3310. This is because, when the upper end of each of the multiple additional shielding members 3410 has a higher position than the upper end of the corresponding main shielding member among the multiple main shielding members 3310, it is difficult to form the cutoff line of the low beam pattern at the correct position.
[0068] Furthermore, multiple additional shielding members 3410 can be formed not only on the corresponding emission lenses among the multiple emission lenses 3210, but also on other adjacent emission lenses in the up and down directions. As described above, this is to prevent light from being incident on the corresponding emission lenses among the multiple emission lenses 3210 and other adjacent emission lenses, thereby preventing light from being irradiated in unnecessary directions.
[0069] In an embodiment of the present invention, the following situation is taken as an example for explanation: each of the multiple additional shielding members 3410 can be formed across the lower end of the corresponding emission lens in the multiple emission lenses 3210 and the upper end of the emission lens adjacent to the lower side of the corresponding emission lens, but this is only an example to help understand the present invention. According to the required light distribution characteristics in the beam pattern formed by the vehicle lamp 1 of the present invention (for example, the position, shape, size, brightness, etc. of the light irradiation area), the position, size, shape, etc. of each of the multiple additional shielding members 3410 can be subjected to various changes.
[0070] In the above embodiment, the case where the main shielding portion 3300 and the additional shielding portion 3400 are included as at least one shielding portion 3300, 3400 is described as an example, but this is only an example to help understand the present invention. According to the light distribution characteristics of the beam pattern formed by the vehicle lamp 1 of the present invention, one of the main shielding portion 3300 and the additional shielding portion 3400 can be formed, or the main shielding portion 3300 and the additional shielding portion 3400 can be omitted.
[0071] Figure 8 is a schematic diagram showing a main shield and an additional shield according to an embodiment of the present invention, Fig. 9 2 is a schematic diagram illustrating a first reflecting portion and a second reflecting portion of a main shield according to an embodiment of the present invention.
[0072] Reference Figure 8 and Fig. 9, each of the plurality of main shields 3310 according to the embodiment of the present invention may include a first reflective portion 3311 and a second reflective portion 3312 located in front of the first reflective portion 3311 .
[0073] In the embodiment of the present invention, the case where the first reflection portion 3311 and the second reflection portion 3312 are deposited or coated on the incident surface 3221 of the second light transmission portion 3220 to form a plurality of main shielding members 3310 is taken as an example for explanation, but it is not limited to this. The plurality of main shielding members 3310 can be formed on the emission surface 3122 of the first light transmission portion 3120 and one of the incident surfaces 3221 of the second light transmission portion 3220.
[0074] At this time, the first reflecting portion 3311 and the second reflecting portion 3312 can be formed to have different reflectivities from each other. When the optical portion 3000 is observed in the front-to-back direction from the incident portion 3100 toward the emission portion 3200 and when the optical portion 3000 is observed from the emission portion 3200 toward the incident portion 3100, images of different colors can be formed by means of a plurality of main shielding members 3310, thereby achieving an aesthetically pleasing appearance design.
[0075] In order to form a cutoff line of the low beam pattern, the first reflective portion 3311 may play a role in blocking the light generated from the light source portion 1000 and incident on the optical portion 3000. For this purpose, Fig.10 As shown, the first reflective portion 3311 may be formed to have a substantially constant reflectivity according to a wavelength band of light.
[0076] The second reflective portion 3312 may be located in front of the first reflective portion 3311. Fig.11 As shown, the second reflecting portion 3312 can be formed to have a relatively high reflectivity for light in a set wavelength band B, so that when external light such as sunlight is incident on the optical portion 3000, the light in the set wavelength band B is reflected and the light in the remaining wavelength bands is absorbed, so that when the vehicle lamp 1 of the present invention is observed from the outside, an image of a color corresponding to the wavelength band reflected by the second reflecting portion 3312 can be achieved.
[0077] For example, when the vehicle is traveling during the day, external light such as sunlight can be incident on the optical portion 3000. Among the external light incident on the optical portion 3000, light of a set wavelength band is reflected by the second reflecting portion 3312, so that when observed from the outside of the vehicle, an image of colors such as red, yellow, and blue corresponding to the wavelength band reflected by the second reflecting portion 3312 can be confirmed. Therefore, even during the day when the vehicle lamp 1 of the present invention is turned off, an aesthetic appearance design can be achieved.
[0078] In other words, when the vehicle is traveling at night, an image produced by light irradiated to form a beam pattern suitable for the purpose of the vehicle lamp 1 of the present invention is confirmed, and when the vehicle is traveling during the day, at least a portion of the external light incident from the outside on the vehicle lamp 1 of the present invention is reflected by the second reflecting portion 3312, thereby being able to confirm an image having a predetermined color.
[0079] At this time, forming an image of a predetermined color by light reflected by the second reflecting portion 3312 can be understood as the second reflecting portion 3312 being formed to have a relatively higher reflectivity for a portion of a wavelength band in a visible light wavelength band that can be visually confirmed.
[0080] In an embodiment of the present invention, the reflectivity for a part of the visible light wavelength band is formed to be relatively higher by the second reflecting portion 3312 because, similar to the first reflecting portion 3311, when the visible light wavelength band as a whole has a constant reflectivity, the image formed by the light reflected by the second reflecting portion 3312 may form a dark or black image, which may reduce the aesthetic sense.
[0081] The second reflecting portion 3312 may be formed by a single deposition layer or by a plurality of deposition layers 3312a, 3312b, 3312c, and 3312d. In the case where the second reflecting portion 3312 is formed by a plurality of deposition layers 3312a, 3312b, 3312c, and 3312d, the second reflecting portion 3312 may include metal layers 3312a and 3312c for adjusting the reflectivity according to the thickness and adjustment layers 3312b and 3312d for adjusting the reflectivity of the wavelength band set by the metal layers 3312a and 3312c.
[0082] In an embodiment of the present invention, the following case is taken as an example: the metal layers 3312a and 3312c may use a material such as aluminum or chromium that adjusts the reflectivity according to the thickness, and the adjustment layers 3312b and 3312d may use a material such as SiO2 or TiO2 that adjusts the reflectivity of the wavelength band set by the metal layers 3312a and 3312c according to the thickness.
[0083] Moreover, in an embodiment of the present invention, the following situation is taken as an example for description: a plurality of deposition layers 3312a, 3312b, 3312c, 3312d are formed using two metal layers 3312a, 3312c and two adjustment layers 3312b, 3312d, and the metal layers 3312a, 3312c and the adjustment layers 3312b, 3312d are alternately deposited in a direction from the emission portion 3200 toward the incident portion 3100.
[0084] At this time, the number, deposition order, materials, etc. of the multiple deposition layers 3312a, 3312b, 3312c, 3312d are not limited to the above examples. The number, deposition order, materials, etc. of the multiple deposition layers 3312a, 3312b, 3312c, 3312d can be subjected to various changes according to the wavelength band reflected by the second reflection portion 3312.
[0085] In the above-mentioned embodiments, the following situation is taken as an example for description: the first reflecting portion 3311 is formed by using a single deposition layer, and the second reflecting portion 3312 is formed by using multiple deposition layers 3312a, 3312b, 3312c, and 3312d, but it is not limited to this. The first reflecting portion 3311 can also be formed by using more than two deposition layers similar to the second reflecting portion 3312.
[0086] In addition, each of the multiple additional shielding members 3410 can include a first reflecting portion 3411 and a second reflecting portion 3412, similar to the above-mentioned multiple main shielding members 3310, and can be deposited or coated on the emission surface 3222 of the second light transmitting portion 3220 in a manner such that light of a set wavelength band in external light such as sunlight incident from the outside is reflected by the second reflecting portion 3412.
[0087] In the embodiments of the present invention, the following situation is taken as an example for explanation: the first reflecting portion 3411 of multiple additional shielding members 3410 may have the same reflectivity as the first reflecting portion 3311 of multiple main shielding members 3310, and the second reflecting portion 3412 of multiple additional shielding members 3410 may have the same reflectivity as the second reflecting portion 3312 of multiple main shielding members 3310, but this is only an example to help understand the present invention and is not limited to this. The first reflecting portion 3411 of multiple additional shielding members 3410 may have a reflectivity different from the reflectivity of the first reflecting portion 3311 of multiple main shielding members 3310, and the second reflecting portion 3412 of multiple additional shielding members 3410 may have a reflectivity different from the reflectivity of the second reflecting portion 3312 of multiple main shielding members 3310, and having different reflectivities from each other can be understood as at least one of the thickness, quantity, formation order, and material of the deposition layers being different from each other.
[0088] In addition, in an embodiment of the present invention, when the first reflecting portion 3411 of the plurality of additional shielding members 3410 has the same reflectivity as the first reflecting portion 3311 of the plurality of main shielding members 3310, and the second reflecting portion 3412 of the plurality of additional shielding members 3410 has the same reflectivity as the second reflecting portion 3312 of the plurality of main shielding members 3310, in the plurality of main shielding members 3310 and the plurality of additional shielding members 3410, the reflectivities of the second reflecting portions 3312 and 3412 may be lower than the reflectivities of the first reflecting portions 3311 and 3411, respectively, to prevent light reflected backward by the first reflecting portions 3411 of the plurality of additional shielding members 3410 from being reflected backward again by the second reflecting portions 3312 of the plurality of main shielding members 3310 and traveling in an unnecessary direction.
[0089] Furthermore, in the embodiment of the present invention, the following case is taken as an example for description: the wavelength band of light reflected by the second reflection portion 3412 of the plurality of additional shielding members 3410 and the wavelength band of light reflected by the second reflection portion 3312 of the plurality of main shielding members 3310 are the same as each other, but the present invention is not limited thereto. The wavelength band of light reflected by the second reflection portion 3412 of the plurality of additional shielding members 3410 and the wavelength band of light reflected by the second reflection portion 3312 of the plurality of main shielding members 3310 may be different from each other. In this case, the image formed by the light reflected by the plurality of additional shielding members 3410 and the image formed by the light reflected by the plurality of main shielding members 3310 may have different colors from each other.
[0090] Fig.12 is a schematic diagram showing the path of light reflected by a main shield and an additional shield according to an embodiment of the present invention.
[0091] Reference Fig.12 When external light OL such as sunlight is incident through the emission portion 3200 of the optical portion 3000 , at least a portion of the external light OL is reflected forward by the second reflection portion 3312 of the main shield 3310 and the second reflection portion 3412 of the additional shield 3410 .
[0092] At this time, when the vehicle lamp 1 of the present invention is observed from the outside, an image of a color corresponding to the wavelength band of light reflected forward by the second reflecting portion 3312 of the main shielding member 3310 and the second reflecting portion 3412 of the additional shielding member 3410 can be confirmed. Therefore, even if the vehicle is running during the day and the vehicle lamp 1 of the present invention is turned off, an image of a predetermined color can be seen, thereby realizing a vehicle lamp with an aesthetic appearance.
[0093] Personnel with ordinary knowledge in the technical field to which the present invention belongs must understand that the present invention can be implemented in other specific forms without changing its technical ideas or essential features. Therefore, the embodiments described above are exemplary in all aspects and should be understood to be non-limiting embodiments. The scope of the present invention is not limited by the aforementioned detailed description, but by the claims, and all changes or deformations derived from the meaning, scope and equivalent concepts of the claims should be interpreted as being included in the scope of the present invention.
