Description

[0001] This application claims priority over Korean application No. 10-2021-0063948, which was filed on May 18, 2021.

[0002] The present disclosure relates to a vehicle light, and in particular a vehicle light which prevents the formation of unnecessary dark streaks in a light pattern.

[0003] In general, a vehicle is equipped with various lights that have a lighting function to make an object located near the vehicle easily visible in poor lighting conditions (e.g. at night), and a signaling function to inform drivers of other vehicles or pedestrians about the vehicle's driving status during the day or at night.

[0004] For example, headlights and fog lights are primarily for illumination, while daytime running lights (DRL), turn signals, taillights, and brake lights are primarily for signaling. Installation standards and specifications for each light are established by laws or regulations to ensure that each light's functions are fully implemented.

[0005] In recent years, not only the functional aspects of a vehicle light, but also the aesthetic aspects perceived by the consumer have had an increasing influence on the purchase decision of a vehicle.

[0006] To this end, research is being actively conducted to improve the external design of a vehicle light so that it has a slimmer shape and forms an optimal beam pattern, while a slim shape is implemented using a plurality of light modules.

[0007] If a vehicle light comprises multiple lighting modules, some of these modules may be used for different purposes than others. Accordingly, some modules may be switched off when the vehicle is in operation during the day or at night. In this case, unnecessary dark streaks may appear, resulting in an overall incomplete lighting pattern.

[0008] Accordingly, there is a need for a device that prevents an incomplete lighting pattern due to dark stripes when some of the majority of lighting modules are switched off, while avoiding a deterioration of the external design.

[0031] Exemplary embodiments of the disclosure are described here with reference to plan and cross-sectional drawings, which are schematic representations of idealized exemplary embodiments of the disclosure. As such, deviations from the shapes shown in the illustrations are to be expected, for example, due to manufacturing techniques and / or tolerances. Therefore, exemplary embodiments of the disclosure should not be understood as being limited to the specific shapes of the areas shown here, but should also include deviations in the shapes that result, for example, from the manufacturing process. In the drawings, the respective components may be shown enlarged or reduced for better illustration.

[0032] The present disclosure is described below with reference to the drawings, which depict a vehicle light according to exemplary embodiments of the present disclosure.

[0033] Fig. Figure 1 is a perspective view showing a vehicle light according to an exemplary embodiment of the present disclosure, and Fig. Figure 2 is a perspective exploded view showing a vehicle light according to an exemplary embodiment of the present disclosure.

[0034] With reference to the Fig. 1 and Fig. 2. According to an exemplary embodiment of the present disclosure, a vehicle light 1 can comprise a plurality of light modules 100 and 200, wherein the plurality of light modules 100 and 200 can be mounted on a front surface of a heat dissipation unit 300. The light emitted by at least one of the plurality of light modules 100 and 200 can be directed forward through multiple guide openings 410 formed in a light guide unit 400 arranged in front of the heat dissipation unit 300, in order to form a beam pattern suitable for the function of the vehicle light 1 of the present disclosure.

[0035] In the exemplary embodiment of the present disclosure, the vehicle light 1 can be used in one function for various lights installed in a vehicle, such as a headlight, a rear light, a brake light, a position light, a daytime running light (DRL), a turn signal light, a reversing light and a fog light, wherein the vehicle light 1 of the present disclosure can be used for a single function among the above-mentioned functions, or can be used for two or more functions.

[0036] Furthermore, in the exemplary embodiment of the present disclosure, an example is described in which the plurality of lighting modules 100 and 200 are arranged in a left-right direction. However, this configuration is only an example to facilitate understanding of the present disclosure, which is not limited to it. The plurality of lighting modules 100 and 200 can be arranged in a left-right direction, an up-down direction, or a combination thereof, depending on the layout or intended design of the vehicle light 1 of the present disclosure.

[0037] The plurality of luminaire modules 100 and 200 can comprise a first luminaire module 100 used for a first function and a second luminaire module 200 used for a second function, wherein the first luminaire module 100 and the second luminaire module 200 can be arranged alternately along the arrangement direction of the plurality of luminaire modules 100 and 200.

[0038] The description that the first lighting module 100 is used for the first function and the second lighting module 200 for the second function does not necessarily mean that the first lighting module 100 and the second lighting module 200 each have fixed functions. It is understood that the first function can refer to the function of the first lighting module 100 in its entirety if the vehicle light 1 of the present disclosure comprises the first lighting module 100 and the second lighting module 200, and the second function can refer to the function of the second lighting module 200 in its entirety if the vehicle light 1 of the present disclosure comprises the first lighting module 100 and the second lighting module 200.

[0039] In particular, if the first lighting module 100 and the second lighting module 200 are used during the day or at night, respectively, all lighting modules 100 and 200 can be switched on to create a complete lighting pattern. However, if one of the first lighting modules 100 or the second lighting module 200 is not in use, some of the multiple lighting modules 100 and 200 may be switched off, resulting in a dark band and potentially an incomplete lighting pattern. Consequently, the exterior design or aesthetics may be compromised.

[0040] For example, if the first lighting module 100 is used as a headlight and the second lighting module 200 is used as a position light at night, both modules 100 and 200 can be switched on to produce a complete lighting pattern. However, if the first lighting module 100 is used as a headlight and the second lighting module 200 is used as a daytime running light, the first module 100 can be switched off, resulting in an incomplete lighting pattern.

[0041] In the exemplary embodiment of the present disclosure, the first lighting module 100 can be configured to emit light in order to allow a complete lighting pattern to still be produced even when the first lighting module 100 is used in the function of a front headlight, and the second lighting module 200 together are used in the function of a position lamp and daytime running light during the day.

[0042] Fig. Figure 3 is a perspective view showing a lighting module according to an exemplary embodiment of the present disclosure, Fig. Figure 4 is a side view showing a lighting module according to an exemplary embodiment of the present disclosure, and Fig. 3 and Fig. Four are examples for the first lighting module 100. With reference to Fig. 3 and Fig. 4. According to an exemplary embodiment of the present disclosure, the first lighting module 100 can comprise a light source unit 110 and an optical unit 120. The light source unit 110 can generate light with a quantity and / or color suitable for the function of the first lighting module 100.

[0043] Fig. Figure 5 is a front view showing a light source unit according to an exemplary embodiment of the present disclosure. Referring to Fig. 5. According to an exemplary embodiment of the present disclosure, the light source unit 110 can comprise a plurality of light emission units 111 and 112 installed on a substrate 113, wherein the plurality of light emission units 111 and 112 can comprise a first light emission unit 111 that generates light to form a first beam pattern and a second light emission unit 112 that generates light to form a second beam pattern.

[0044] In this case, in the exemplary embodiment of the present disclosure, the majority of the light emission units 111 and 112 can be installed on the same substrate 113. This configuration can make it possible to reduce the distance between the majority of the light emission units 111 and 112.

[0045] Each of the plurality of light emission units 111 and 112 can comprise at least one light emission module. In an exemplary embodiment of the present disclosure, an example is described in which the first light emission unit 111 comprises a single light emission module, and the second light emission unit 112 comprises several light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g, and 112h arranged around (e.g., enclosing or surrounding) the first light emission unit 111. However, the present disclosure is not limited thereto. The number of light emission modules contained in both the first light emission unit 111 and the second light emission unit 112 can be varied depending on the beam pattern to be formed by the first light emission unit 111 and the second light emission unit 112.

[0046] In the first light emission unit 111, the center of the light emission area can be located on or near the optical axis Ax of the optical unit 120. This configuration can allow the first beam pattern to be used for a main function of the first luminaire module 100, generating a greater amount of light as it approaches the center of the light emission areas of the first light emission unit 111.

[0047] The second light emission unit 112 can serve as an auxiliary function of the first luminaire module 100 to generate a second beam pattern with a relatively low brightness compared to the first beam pattern. Accordingly, the second light emission unit 112 can be arranged around the first light emission unit 111, i.e., spaced from the first light emission unit 111 at a predetermined distance from the optical axis Ax of the optical unit 120.

[0048] In an exemplary embodiment of the present disclosure, although an example is described in which the second light-emitting unit 112 comprises eight light-emitting modules 112a, 112b, 112c, 112d, 112e, 112f, 112g and 112h surrounding the first light-emitting unit 111, this configuration is intended to allow the light to be emitted as a whole from the optical unit 120 when the second beam pattern is formed, and the present disclosure is not limited thereto. Based on the luminous pattern to be formed by the first luminaire module 100 when the second beam pattern is formed, as described in the Fig. As shown in Figures 6 to 8, the second light emission unit 112 can comprise at least one light emission module arranged in the left-right direction, the top-bottom direction or a combination thereof with respect to the first light emission unit 111.

[0049] A detailed description of the luminous pattern formed depending on the position of the at least one light emission module contained in the second light emission unit 112 in relation to the first light emission unit 111 is described below.

[0050] The optical unit 120 can comprise at least one lens 121 and 122 arranged upstream of the light source unit 110. An exemplary embodiment of the present disclosure describes a case in which at least one lens 121 and 122 comprises a first lens 121 arranged upstream of the light source unit 110 and a second lens 122 arranged upstream of the first lens 121. Although the exemplary embodiment of the present disclosure describes an example in which the optical unit 120 comprises two lenses 121 and 122, the present disclosure is not limited thereto. The optical unit 120 can include at least one lens based on the shape and / or size of the luminous pattern to be formed by the vehicle lamp 1 of the present disclosure.

[0051] For example, an aspherical lens that focuses the light generated by the light source unit 110 can be used as the first lens 121 so that the light generated by the light source unit 110 reaches the second lens 122 with minimal loss. However, the present disclosure is not limited to this, and a TIR lens (TIR = total internal reflection) or a Fresnel lens that can focus the light generated by the light source unit 110 can be used as the first lens 121.

[0052] The second lens 122 can cause a first beam pattern or a second beam pattern to be formed by the first luminaire module 100 of the present disclosure, the incident light passing through the first lens 121.

[0053] Fig. Figure 9 is a side view showing a second lens according to an exemplary embodiment of the present disclosure. Referring to Fig. 9 According to the exemplary embodiment of the present disclosure, the second lens 122 can comprise a plurality of entrance lenses 122a onto which the light passing through the first lens 121 can fall, a plurality of exit lenses 122b for emitting the light falling onto the plurality of entrance lenses 122a, and a plurality of shields 122c arranged between an entrance lens and an exit lens, which correspond to each other under the plurality of entrance lenses 122a and the plurality of exit lenses 122b, in order to enable the first beam pattern or the second beam pattern to have a required shape and / or size.

[0054] In the exemplary embodiment of the present disclosure, the plurality of entrance lenses 122a can be arranged on an incidence surface of the first optical element 122d, wherein the plurality of exit lenses 122b can be arranged on an exit surface of the second optical element 122e. The second optical element 122e can be arranged such that an incidence surface of it is opposite the exit surface of the first optical element 122d. Furthermore, the plurality of shields 122c on the incidence surface of the second optical element 122e can be formed by deposition or coating. Since in this case the plurality of entrance lenses 122a and the plurality of exit lenses 122b have relatively short focal lengths, a microlens can be used due to the advantages of miniaturization.

[0055] The light emitted by the first luminaire module 100 described above can be guided forward through the guide opening 410 formed in the light guide unit 400. In order for the first and second beam patterns to provide the required amount of light, a sufficient amount of light may be necessary to pass through the guide opening 410. Accordingly, the first light emission unit 111 and the second light emission unit 112 can be arranged within a distance range defined with respect to the optical axis Ax of the optical unit 120.

[0056] In other words, with regard to an auxiliary function of the first luminaire module 100, the second light emission unit 112 can be spaced apart from the first light emission unit 111 by a predetermined distance. If the first light emission unit 111 and the second light emission unit 112 are positioned too far apart, the light generated by the second light emission unit 112 may not reach the first lens 121, resulting in light loss. Since the amount of light transmitted through the guide aperture 410 may decrease in this case, the second beam pattern may not achieve the required brightness. Therefore, it may be necessary for the second light emission unit 112 to be positioned within a predetermined distance range from the first light emission unit 111.

[0057] For this purpose, in the exemplary embodiment of the present disclosure, as in Fig. As shown in Figure 10, the second light emission unit 112 is arranged within a preset area A with a size of approximately 50% relative to the size of the guide aperture 410, centered on the optical axis Ax of the optical unit 120. The description that the second light emission unit 112 is arranged within the preset area A can be understood to mean that at least one light emission module contained in the second light emission unit 112 is arranged within the preset area A, wherein the distance between the second light emission unit 112 and the first light emission unit 111 can vary depending on the size of the preset area A.

[0058] In this case, in the exemplary embodiment of the present disclosure, the first light emission unit 111 and the second light emission unit 112 can be installed on the same substrate 113, so that the first light emission unit 111 and the second light emission unit 112 can be arranged more easily within the preset area A.

[0059] Fig. Figure 11 shows various light patterns of the second beam pattern formed by the second light emission unit 112 as described above. Fig. Figure 11 shows a case in which eight light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g and 112h are contained in the second light emission unit 112, wherein each light emission module 112a, 112b, 112c, 112d, 112e, 112f, 112g and 112h is arranged in the up-down direction, the left-right direction and the diagonal direction of the first light emission unit 111, respectively.

[0060] Referring to Fig. 11 different lighting patterns I can be formed depending on whether each of a plurality of light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g and 112h is switched on or all light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g and 112h are switched on.

[0061] In this context, the multiple light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g, and 112h can be designated as the first to eighth light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g, and 112h, respectively, in a clockwise direction from the light emission module 112a, which is arranged on one upper side in a vertical direction with respect to the first light emission unit 111. Depending on whether the first to eighth light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g, and 112h are switched on individually or simultaneously, a different luminous pattern I can be generated. Furthermore, the light from at least one of the first to eighth light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g and 112h can be generated on the basis of a desired luminous pattern of the second beam pattern.

[0062] According to the present disclosure, the number of the second light emission unit 112 is not limited to eight, and the number and / or positions of the light emission modules contained in the second light emission unit 112 can be varied depending on the desired light pattern. The light pattern produced by the first light module 100 can also be varied based on the number and / or positions of the light emission modules contained in the second light emission unit 112.

[0063] Furthermore, in Fig. Figure 11 shows the positions of the light emission module switched on below the first to eighth light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g, and 112h, and the corresponding illuminated image, as if they were opposite each other with respect to the optical axis Ax of the optical unit 120. This is because, when using an aspherical lens as the first lens 121, the image formed by the light transmitted through the aspherical lens may appear inverted with respect to the position of the light emission module. The positions of the switched-on light emission module and the correspondingly formed illuminated image may lie in the same direction with respect to the optical axis Ax of the optical unit 120, depending on the type of first lens 121 used.

[0064] Returning to the Fig. 3 and Fig. 4. The optical unit 120 can include a reflector 123 arranged between the first lens 121 and the second lens 122 to reflect at least some of the light emitted by the first lens 121. In the exemplary embodiment of the present disclosure, the rear end of the reflector 123 can be located near the lower end of the first lens 121 and the front end near the lower end of the second lens 122, but this is only an example for better understanding of the present disclosure. The reflector 123 can be located at at least one of the upper or lower ends of the first lens 121 and the second lens 122.

[0065] The reflector 123 can be used to gently change the brightness of the boundary line of the illuminated image formed by the first lighting module 100 in order to allow an expansion of the boundary line of the illuminated image, and thus the illuminated image formed by the second light emission unit 112 can be expanded or diffused.

[0066] Fig. Figure 12 is a perspective view showing a reflector according to an exemplary embodiment of the present disclosure. Referring to Fig. 12. According to the exemplary embodiment of the present disclosure, the reflector 123 can be shaped such that the rear end 123a has a shape corresponding to the first lens 121 which is arranged at the rear of the reflector 123, wherein the front end 123b has a shape corresponding to the second lens 122 which is arranged in front of the reflector 123.

[0067] In the exemplary embodiment of the present disclosure, since an aspherical lens is described as an example of the first lens 121, the rear end 123a of the reflector 123 can be shaped to have a curved form corresponding to the shape of the emission surface of the aspherical lens. Since the multiple entrance lenses 122a, like the second lens 122, are arranged to have a planar form that is substantially perpendicular to the optical axis Ax of the optical unit 120, the front end 123b of the reflector 123 can have a linear form (e.g., a flat form). However, this configuration is only an example for better understanding of the present disclosure, which is not limited to it. Depending on the forms of the first lens 121 and the second lens 122, the form of the rear end 123a and the front end 123b of the reflector 123 can be varied accordingly.

[0068] Furthermore, a reflective surface 123c of the reflector 123 can have a concave curved shape with respect to the optical axis Ax, so that the light reflected from the reflector 123 can fall onto the second lens 122. The reflective surface 123c can be formed by applying or coating a material with high reflectivity, such as aluminum or chromium, or it can consist of a white material with relatively high reflectivity.

[0069] Fig. Figure 13 shows a light pattern produced by a vehicle light according to an exemplary embodiment of the present disclosure. Referring to Fig. 13 In the vehicle light 1 of the present disclosure, when the vehicle is in operation at night, the first light emission unit 111 of the first lighting module 100 can be switched on to provide functionality as a front headlight, while the second lighting module 200 can be used to provide functionality as a position light. Consequently, the first light pattern I1 of the first lighting module 100 and the light pattern I2 of the second lighting module 200 can be formed alternately to produce a complete light pattern as a whole.

[0070] When the vehicle is in operation during the day, the second light emitting unit 112 of the first lighting module 100 can be switched on for a daytime running light support function (i.e., an auxiliary function), while the second lighting module 200 can be used for a daytime running light function. Consequently, the first light pattern I1 can be formed alternately by the first lighting module 100 and the light pattern I2 by the second lighting module 200 to produce a substantially complete light pattern as a whole, similar to the case when the vehicle is driven at night.

[0071] In particular, it shows Fig.13 An example is given in which only the fifth light emission module 112e of the first to eighth light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g and 112h described above is switched on when the first light emission module 100 is used for a daytime running light support function. However, the present disclosure is not limited to this. When the first light emission module 100 is used for daytime running light support, the shape of the light pattern formed by the first light emission module 100 can be varied based on the light emission module to be switched on from the first to eighth light emission modules 112a, 112b, 112c, 112d, 112e, 112f, 112g and 112h, depending on the desired light pattern.

[0072] In the exemplary embodiment of the present disclosure, the first light emission unit 111 can be switched on and the second light emission unit 112 switched off during the night, while during the day the first light emission unit 111 can be switched off and the second light emission unit 112 switched on. However, this is only an example for a better understanding of the present disclosure, which is not limited to it. Based on the function of the first lighting module 100, either the first light emission unit 111 or the second light emission unit 100 can be switched on during the day, while the other can be switched on at night.

[0073] As described above, in the vehicle light 1 of the present disclosure, the first lighting module 100 and the second lighting module 200 can be arranged alternately, and when the vehicle is in operation during the night and during the day, a lighting pattern can be formed by the first lighting module 100 and the second lighting module 200, thus preventing an incomplete lighting pattern from being formed by some of the first lighting modules 100 and the second lighting modules 200 being switched off. Therefore, any impairment of the external design or aesthetics can be prevented.

[0074] In conclusion to the detailed description, the person skilled in the art will recognize that many variations and modifications can be made to the exemplary embodiments without substantially departing from the principles of the present disclosure. Therefore, the disclosed exemplary embodiments are used only in a general and descriptive sense, and not in a limiting sense.
