Description

Technical Field

[0001] The invention relates to a vehicle lamp, and more specifically, to a vehicle lamp capable of forming a light distribution pattern comprising multiple patterned areas even with a simplified structure. Background Technology

[0002] The vehicle is equipped with a variety of lights with the following functions: illumination function, used to easily identify objects around the vehicle when driving at night; and signal function, used to inform drivers of surrounding vehicles or pedestrians of the vehicle's driving status.

[0003] For example, headlights and fog lights are mainly designed for illumination, while turn signals, taillights, and brake lights are mainly designed for signaling. The installation standards and specifications of these lights have been stipulated by relevant regulations to ensure that they can fully perform their respective functions.

[0004] Recently, research has been actively conducted on reducing the size of luminaires by using microlenses with relatively short focal distances, in which light emitted from multiple microlenses forms a light distribution pattern with the desired shape or size.

[0005] At this point, when the light distribution pattern includes multiple pattern areas, it is necessary to equip each pattern area with a separate optical system. In this case, the structure of the luminaire becomes complex and the cost increases. Therefore, a solution is needed that can form a light distribution pattern including multiple pattern areas even with a simplified structure.

However, the invention is not limited to the embodiments disclosed below, which can be implemented in various different forms. These embodiments are provided only to fully disclose the invention and to inform those skilled in the art of the scope of the invention, which is defined only by the scope of the claims.

[0050] Therefore, in some embodiments, to avoid the invention being interpreted vaguely, well-known process steps, well-known structures and well-known technologies are not specifically described.

[0051] The terminology used in this specification is for illustrative purposes and not intended to limit the invention. In this specification, unless otherwise stated, singular forms include plural forms as well. The terms "comprises" and / or "comprising" as used in this specification are used to mean, without excluding, the presence or additional meaning of one or more other constituent elements, steps, operations, and / or components besides those mentioned. Furthermore, "and / or" includes each of the mentioned items and all combinations thereof.

[0052] Furthermore, the embodiments described in this specification will be illustrated with reference to cross-sectional views and / or schematic diagrams, which serve as idealized examples of the present invention. Therefore, the form of the schematic diagrams may be modified depending on manufacturing techniques and / or allowable tolerances. Accordingly, the embodiments of the present invention are not limited to the specific forms illustrated, and variations in form resulting from manufacturing processes are also included. Moreover, in the various figures illustrated in the embodiments of the present invention, for ease of explanation, individual components may be shown enlarged or reduced to some extent. Throughout this specification, the same reference numerals refer to the same components.

[0053] Hereinafter, the present invention will be described with reference to the accompanying drawings, which illustrate vehicle lamps according to embodiments of the present invention.

[0054] Figure 1 and Figure 2 This is a perspective view showing a vehicle lamp according to an embodiment of the present invention. Figure 3 This is a side view showing a vehicle lamp according to an embodiment of the present invention.

[0055] Reference Figure 1According to an embodiment of the present invention, a vehicle lamp 1 may include a light source 100, an optical part 200, and a light transmission part 300. The light source 100, the optical part 200, and the light transmission part 300 may be housed in an internal space formed by a lamp housing (not shown) and a housing lens (not shown) attached to the lamp housing to direct light toward the outside of the vehicle.

[0056] In embodiments of the present invention, the vehicle lamp 1 can be used for a variety of functions, such as illumination (e.g., headlights to ensure the driver's visibility when the vehicle is driving at night), signaling (e.g., position lights, daytime running lights, turn signals, brake lights, etc. to inform drivers or pedestrians of the vehicle's driving status), and forming a light distribution pattern composed of text, images, or combinations thereof on the road surface around the vehicle to convey various information to the driver or pedestrian. The vehicle lamp 1 of the present invention can be used as a single function among the above functions, or two or more functions can be used together.

[0057] Hereinafter, in an embodiment of the present invention, the case in which the vehicle lamp 1 of the present invention is used to form a light distribution pattern on the road surface around the vehicle will be described as an example. The light distribution pattern includes at least one pattern area, but is not limited thereto. The vehicle lamp 1 of the present invention can also be similarly applied to form a light distribution pattern for lighting or signaling functions.

[0058] The light source 100 can produce light of a color or brightness suitable for the function of the vehicle lamp 1 of the present invention, and the light produced from the light source 100 can travel in such a way that it is incident on the optical unit 200 located in front of the light source 100.

[0059] At this time, the situation where the optical unit 200 is located in front of the light source unit 100 is assumed to be the direction in which the light irradiated from the vehicle lamp 1 of the present invention is in front. The actual direction represented by "in front" may vary depending on the position or direction in which the vehicle lamp 1 of the present invention is installed.

[0060] Furthermore, in the case where the light distribution pattern is formed on the road surface around the vehicle in the vehicle lamp 1 of the present invention, at least one of the light source unit 100, optical unit 200 and light transmission unit 300 can be arranged obliquely toward the road surface with the horizontal direction as a reference. In the embodiment of the present invention, the case in which the light source unit 100, optical unit 200 and light transmission unit 300 are arranged as a whole with the horizontal direction S as a reference and obliquely toward the road surface by a predetermined angle θ will be described as an example.

[0061] The light source unit 100 may include a plurality of light sources 110, 120, and 130. In the embodiments of the present invention, the purpose of including a plurality of light sources 110, 120, and 130 in the light source unit 100 is to form a light distribution pattern including a plurality of pattern areas corresponding to the plurality of light sources 110, 120, and 130 by means of the vehicle lamp 1 of the present invention.

[0062] At this time, each of the multiple pattern areas can have the shape of text, pattern, or a combination thereof, and thus, the light distribution pattern including multiple pattern areas can also have the shape of text, pattern, or a combination thereof.

[0063] In an embodiment of the present invention, the case in which the light source unit 100 includes three light sources 110, 120, and 130 will be described as an example. However, this is because the light distribution pattern formed by the vehicle lamp 1 of the present invention includes three pattern areas, and the number of light sources included in the light source unit 100 may vary depending on the number of pattern areas included in the light distribution pattern formed by the vehicle lamp 1 of the present invention.

[0064] The light distribution pattern includes multiple pattern areas, which can be understood as including multiple pattern areas formed to have the same size at the same distance from the vehicle, or including multiple pattern areas formed to have different sizes at the same distance from the vehicle, or including multiple pattern areas formed to have the same size at different distances from the vehicle, or including multiple pattern areas formed to have different sizes at different distances from the vehicle.

[0065] In the embodiments of the present invention, the case in which multiple light sources 110, 120, and 130 use semiconductor light-emitting elements such as light-emitting diodes (LEDs) is used as an example for explanation, but it is not limited to this. The multiple light sources 110, 120, and 130 can use not only LEDs, but also various types of light sources such as laser diodes (LDs) or bulbs. Depending on the type of light source, optical elements such as lenses, mirrors, and reflectors can be added.

[0066] In the embodiments of the present invention, the plurality of light sources 110, 120, and 130 are referred to as the first light source 110, the second light source 120, and the third light source 130.

[0067] The optical unit 200 can transmit light generated from each of the plurality of light sources 110, 120, 130 to form pattern areas corresponding to the plurality of light sources 110, 120, 130 respectively.

[0068] Multiple light sources 110, 120, and 130 can be turned on or off simultaneously, or they can be turned on or off sequentially. When multiple light sources 110, 120, and 130 are turned on or off sequentially, the animation effect can be achieved by the pattern area formed by each of the multiple light sources 110, 120, and 130.

[0069] Figure 4 and Figure 5 This is a perspective view showing the optical section according to an embodiment of the present invention. Figure 6 and Figure 7 This is an exploded perspective view showing the optical part according to an embodiment of the present invention. Figure 8 This is a front view showing the optical section according to an embodiment of the present invention.

[0070] Reference Figures 4 to 8 The optical unit 200 of the present invention may include a plurality of incident lenses 210 (211, 212, 213), a plurality of exit lenses 220 (221, 222, 223) and a plurality of blocking members 230 (231, 232, 233).

[0071] The optical unit 200 can be divided into multiple transmission regions A1, A2, and A3 that transmit light generated from each of the multiple light sources 110, 120, and 130. In embodiments of the present invention, the multiple transmission regions A1, A2, and A3 are referred to as the first transmission region A1 that transmits light from the first light source 110, the second transmission region A2 that transmits light from the second light source 120, and the third transmission region A3 that transmits light from the third light source 130.

[0072] At this time, the optical section 200 is divided into three transmission regions A1, A2, and A3 because the light source section 100 includes three light sources 110, 120, and 130. Depending on the number of light sources included in the light source section 100, the optical section 200 can be composed of one transmission region or divided into two or more transmission regions.

[0073] In the following embodiments of the present invention, the patterned area formed by light transmitted through the first transmission region A1 is referred to as the "first patterned area", the patterned area formed by light transmitted through the second transmission region A2 is referred to as the "second patterned area", and the patterned area formed by light transmitted through the third transmission region A3 is referred to as the "third patterned area".

[0074] Multiple incident lenses 210 can be arranged on the incident surface 241 of an optical component 240 made of a light-transmitting material such as glass, and multiple exit lenses 220 can be arranged on the exit surface 242 of the optical component 240. Light incident on each of the multiple incident lenses 210 can be incident through the optical component 240 to the exit lenses of the multiple exit lenses 220 that correspond to the multiple incident lenses 210 and then exit.

[0075] At this time, the multiple incident lenses 210 and multiple exit lenses 220 use microlenses with relatively short focal lengths, thereby reducing the size of the optical section 200.

[0076] In the embodiments of the present invention, the example is given in which a plurality of incident lenses 210 and a plurality of exit lenses 220 correspond to each other in a one-to-one manner. However, the invention is not limited thereto. The plurality of incident lenses 210 and a plurality of exit lenses 220 may correspond to each other in a one-to-one, one-to-many, many-to-one, or many-to-many manner according to the light distribution characteristics such as the shape, size, and position of the light distribution pattern formed by the vehicle lamp 1 of the present invention.

[0077] The plurality of blocking members 230 can serve to block a portion of the light incident on each of the plurality of exiting lenses 220. Each of the plurality of blocking members 230 may include an opening 230a that allows light to pass through, and the shape or size of the patterned area may vary depending on the shape or size of the opening 230a by the light emitted through each of the plurality of exiting lenses 220.

[0078] In an embodiment of the present invention, an example is given where multiple blocking elements 230 are formed on the incident surface 241 of the optical component 240 by deposition or coating, but this is not a limitation. Multiple blocking elements 230 may be formed on at least one of the incident surface 241 and the exit surface 242 of the optical component 240, or they may be formed inside the optical component 240. In the case where multiple blocking elements 230 are formed inside the optical component 240, it can be understood that the optical component 240 is configured to have two or more elements, and multiple blocking elements 230 are located between them.

[0079] In the optical section 200, the size of each of the multiple transmission regions A1, A2, A3 can be different from each other depending on the size of the pattern area formed by each of the multiple transmission regions A1, A2, A3 and the distance of the pattern area from the vehicle.

[0080] For example, in the case where the first pattern area formed by the first transmission area A1 is formed at the farthest distance from the vehicle, and the third pattern area formed by the third transmission area A3 is formed at the closest distance from the vehicle, the first transmission area A1 has the largest size and the third transmission area A3 has the smallest size. This is because in order to make the pattern areas formed at different distances from the vehicle have uniform brightness, the farther away the pattern area is from the vehicle, the higher the light intensity is required.

[0081] At this time, the distance between the first pattern area and the third pattern area and the vehicle can be understood as the distance between the center of each of the first pattern area and the third pattern area from the vehicle lamp 1 of the present invention along the direction in which the first pattern area and the third pattern area are formed and the vehicle.

[0082] Furthermore, among the multiple transmission regions A1, A2, and A3, the first transmission region A1 has the largest size and the third transmission region A3 has the smallest size, which is because the larger the size of the pattern region, the higher the amount of light required to achieve uniform brightness.

[0083] Furthermore, when the first pattern area to the third pattern area, formed by the first transmission area A1, the second transmission area A2, and the third transmission area A3 respectively, have the same size at different distances from the vehicle, or when the first pattern area to the third pattern area have different sizes at the same distance from the vehicle, the sizes of the first transmission area A1, the second transmission area A2, and the third transmission area A3, together with the sizes of the exiting lenses and blocking members belonging to the first transmission area A1, the second transmission area A2, and the third transmission area A3 respectively among the plurality of exiting lenses 220, can be different.

[0084] In the embodiments of the present invention, among the plurality of exiting lenses 220, the exiting lens belonging to the first transmission region A1 is referred to as the "first exiting lens", the exiting lens belonging to the second transmission region A2 is referred to as the "second exiting lens", and the exiting lens belonging to the third transmission region A3 is referred to as the "third exiting lens".

[0085] Furthermore, among the multiple blocking members 230, the blocking member belonging to the first transmission region A1 is called the "first blocking member", the blocking member belonging to the second transmission region A2 is called the "second blocking member", and the blocking member belonging to the third transmission region A3 is called the "third blocking member".

[0086] Figure 9 This is a schematic diagram illustrating exit lenses with different diameters depending on the size of the transmission area according to an embodiment of the present invention.

[0087] Reference Figure 9 Among the first transmission region A1, the second transmission region A2, and the third transmission region A3, the first pattern region formed by the light transmitted through the first transmission region A1 is formed at the distance farthest from the vehicle and thus has the largest size, while the third pattern region formed by the light transmitted through the third transmission region A3 is formed at the distance closest to the vehicle and thus has the smallest size.

[0088] At this time, the first exiting lens 221 belonging to the first transmission region A1 can have the smallest diameter d1, and the third exiting lens 223 belonging to the third transmission region A3 can have the largest diameter d3. This is because the openings of the multiple blocking members 230 belonging to the first transmission region A1, the second transmission region A2, and the third transmission region A3 are different from each other.

[0089] Figure 10 This is a schematic diagram illustrating a blocking member with openings of different sizes depending on the size of the transmission area, according to an embodiment of the present invention.

[0090] Reference Figure 10 Among the multiple blocking members 230, the opening 231a of the first blocking member 231 belonging to the first transmission region A1 can be formed to have the smallest size, and the opening 233a of the third blocking member 233 belonging to the third transmission region A3 can be formed to have the largest size. Accordingly, the first exiting lens 221 can have the smallest diameter, and the third exiting lens 223 can have the largest diameter.

[0091] This is because when multiple blocking members 230 have openings 230a of the same size, the farther the light is shone from the vehicle, the more the light is diffused, thus forming a relatively larger pattern area. Therefore, the farther the light is shone from the vehicle, the smaller the size of the openings 230a of the blocking members 230 becomes, so that even pattern areas formed at different distances from the vehicle can have the same size.

[0092] In the aforementioned Figure 9 and Figure 10 The following example illustrates this: Among multiple transmission regions A1, A2, and A3, the transmission region corresponding to the pattern region formed at a greater distance from the vehicle has a larger size, while the opening of the exit lens and the blocking member has a smaller size, so that the first to third pattern regions are formed to the same size at different distances from the vehicle. However, this is not a limitation. Alternatively, even when the first to third pattern regions are formed to have different sizes at the same distance from the vehicle, among the multiple transmission regions A1, A2, and A3, the transmission region corresponding to the pattern region with the larger size has a larger size, and the opening of the exit lens and the blocking member has a larger size, so that the first to third pattern regions can be formed to the same distance from the vehicle with different sizes.

[0093] As a result, when the first pattern area to the third pattern area have the same size and are formed at different distances from the vehicle, the sizes of the first transmission area A1, the second transmission area A2, and the third transmission area A3 are different from each other, and the diameters d1, d2, and d3 of the first exit lens 221, the second exit lens 222, and the third exit lens 223 are different from each other, thereby achieving the desired effect. Figure 11 As shown, when light L1, L2, and L3 generated from the first light source 110, the second light source 120, and the third light source 130 respectively illuminate the road surface around the vehicle to form the first pattern area P1, the second pattern area P2, and the third pattern area P3, even if the first pattern area P1, the second pattern area P2, and the third pattern area P3 are formed at different distances g1, g2, and g3 from the vehicle, they can have the same size and brightness.

[0094] at this time, Figure 11 This is an example of a situation where the first pattern area P1 is formed at the distance furthest from the vehicle, the third pattern area P3 is formed at the distance closest to the vehicle, and the first pattern area P1, the second pattern area P2, and the third pattern area P3 have the same size.

[0095] In addition, such as Figure 12 As shown, when the first pattern region P1, the second pattern region P2, and the third pattern region P3 have different sizes and are formed at the same distance g from the vehicle, the first transmission region A1, which corresponds to the first pattern region P1 with the largest size among the multiple transmission regions A1, A2, and A3, can have the largest size, and the opening 231a of the first exit lens 221 and the first blocking member 231 can have the largest size. The third transmission region A3, which corresponds to the third pattern region P3 with the smallest size, can have the smallest size, and the opening 233a of the third exit lens 223 and the third blocking member 233 can have the smallest size, so that the first pattern region P1, the second pattern region P2, and the third pattern region P3 have uniform brightness.

[0096] In the foregoing embodiments, examples were given of first pattern areas to third pattern areas formed at different distances from the vehicle having the same size and brightness, and of first pattern areas to third pattern areas formed at the same distance from the vehicle having different sizes. However, this is only one example to help understand the present invention and is not limited thereto. The size of each of the first transmission area A1, the second transmission area A2, and the third transmission area A3, the diameter of each of the plurality of exiting lenses 220, the size of the opening 230a of each of the plurality of blocking members 230, etc., can vary depending on the size of each of the first pattern area P1, the second pattern area P2, and the third pattern area P3 or the distance from the vehicle where each of the first pattern area P1, the second pattern area P2, and the third pattern area P3 is formed.

[0097] In addition, the aforementioned Figure 11 and Figure 12 This is one example of a situation where the first light source 110, the second light source 120, and the third light source 130 are simultaneously illuminated, forming the first pattern area P1, the second pattern area P2, and the third pattern area P3 simultaneously. However, it is not limited to this; when the first light source 110, the second light source 120, and the third light source 130 are illuminated sequentially, such as... Figure 13 As shown, the first pattern area P1, the second pattern area P2, and the third pattern area P3 can be formed sequentially to achieve an animation effect. This animation effect can be used for design purposes that express the inherent personality of a vehicle, or for purposes that can more clearly identify the direction of travel of a vehicle, such as turn signals or reversing lights, but is not limited thereto. The first light source 110, the second light source 120, and the third light source 130 can be used for various purposes that require providing information by lighting lights sequentially.

[0098] The light transmission unit 300 can concentrate and transmit the light generated from each of the multiple light sources 110, 120, and 130 to the optical unit 200.

[0099] Figure 14 This is a perspective view showing the light transmission section according to an embodiment of the present invention. Figure 15 This is a front view showing the light transmission section according to an embodiment of the present invention.

[0100] Reference Figure 14 and Figure 15 The light transmission unit 300 may include a plurality of light guides 310, 320, and 330 to guide light generated from each of the plurality of light sources 110, 120, and 130 to the optical unit 200.

[0101] In embodiments of the present invention, the plurality of light guides 310, 320, and 330 can convert light generated from each of the plurality of light sources 110, 120, and 130 into parallel light and transmit it to the optical unit 200, so that the light generated from each of the plurality of light sources 110, 120, and 130 can be uniformly transmitted to each of the plurality of transmission regions A1, A2, and A3, thereby making the patterned area formed by transmitting light from each of the plurality of transmission regions A1, A2, and A3 have uniform brightness.

[0102] In an embodiment of the present invention, an example is given in which multiple light guides 310, 320, and 330 use lenses with a forward-convex shape in order to focus light. However, this is only one example to help understand the present invention and is not limited thereto. The multiple light guides 310, 320, and 330 can use various optical elements capable of focusing light, such as reflectors or mirrors, instead of lenses.

[0103] The incident surfaces of each of the multiple light guides 310, 320, and 330 are formed as a single unit, while the exit surfaces 311, 321, and 331 are formed independently, thereby enabling easy assembly of the light transmission unit 300.

[0104] Multiple light guides 310, 320, and 330 may have different dimensions from each other because multiple transmission regions A1, A2, and A3 have different dimensions from each other.

[0105] For example, among the multiple light guides 310, 320, and 330, the first light guide 310, which guides light incident into the first transmission region A1, has the largest size, while the third light guide 330, which guides light incident into the third transmission region A3, has the smallest size.

[0106] When the aforementioned vehicle lamp 1 of the present invention forms a light distribution pattern including multiple pattern areas on the road surface around the vehicle, it can share some of the constituent elements used to form the multiple pattern areas, thereby reducing the number of parts used to form the multiple pattern areas, thereby reducing the structure and lowering the cost.

[0107] Those skilled in the art will understand that this invention can be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as exemplary in all respects, not limiting. The scope of this invention is not limited by the foregoing detailed description, but by the claims. All modifications or variations derived from the meaning and scope of the claims and their equivalents should be interpreted as included within the scope of this invention.
