Abstract

The present invention relates to a lamp for a vehicle, capable of implementing a linear beam. According to the present invention, in the lamp for a vehicle, light irradiated from each of a plurality of light sources is formed as a unit beam elongated in a direction in which the light sources are arranged, through a non-spherical lens and a diffusion lens, such that one linear beam can be irradiated with a relatively small structure, thereby improving space efficiency. In addition, the lamp for a vehicle, of the present invention, can irradiate a linear beam with high efficiency, since light irradiated from each light source is condensed by the non-spherical lens and then passes through the diffusion lens to be formed into a unit beam. Alternatively, the lamp for a vehicle, of the present invention, can reflect light irradiated laterally from each light source, toward the diffusion lens, thereby irradiating a high-efficiency linear beam formed of a plurality of unit beams.

Description

car lamps

[0001] The present invention relates to an automobile lamp, and more particularly, to an automobile lamp capable of implementing a linear beam.

[0002] In general, LEDs are lights installed at the rear or front of a moving vehicle, and they are lights that shine light around the vehicle to secure visibility around the vehicle at night.

[0003] And these lights are simply made by placing a lamp (LED) and a lamp housing inside a light chamber that forms an open interior space, and also including a protective cover that covers and blocks the open light chamber and a reflector inside.

[0004] The lens or transparent cover installed in front of the lamp here is simply to project the light emitted by the light emitting body forward.

[0005] Therefore, since the light from the light source installed inside the lamp housing is very straight, it cannot spread light widely around the moving vehicle, and in addition, it can directly shine into the eyes of the driver of the moving vehicle located behind or the driver of the oncoming vehicle, which can cause a risk of an accident.

[0006] In addition, in order to widely illuminate the vehicle with a strong straight-line light source, if multiple light sources and reflectors are installed together, there is a problem that the manufacturing and installation costs increase accordingly.

[0007] To solve this problem, the inventor of the present invention proposed a lens for a vehicle LED lamp, as published in Korean Patent Publication Nos. 10-0978017 and 10-1011819.

[0008] Meanwhile, vehicle lamps were merely a means of lighting and signaling, but recently, the proportion of lamps in terms of design is increasing day by day.

[0009] In other words, not only is the functional aspect of ensuring driver visibility, which is the basic role of vehicle lamps, and thus helping to drive safely, but the aesthetic aspect that consumers perceive through improved design also has a great influence on their decision to purchase a vehicle.

[0010] To this end, active research is being conducted to improve the exterior design of vehicle lamps by making them slimmer. However, when the size of the lens is reduced to achieve a slimmer shape, there is a possibility that the light efficiency will decrease because light loss occurs due to light from the light source not entering the lens.

[0011] In addition, in order to implement a slim linear beam, there is a disadvantage in that the size of the lamp increases in the direction of extension of the beam as multiple light sources are spaced apart from each other by a certain distance.

[0012] Therefore, a method is required that can prevent a decrease in optical efficiency while implementing a slim linear beam and reduce both size and volume.

[0013] Accordingly, the inventor of the present invention has continuously researched and developed a vehicle lens, and has subsequently filed a patent for a lamp structure that can spread light from a light source with strong linearity widely up and down or left and right, while improving light collection efficiency, and can implement a linear beam by continuously arranging light sources in the left and right or up and down directions.

[0014] The present invention has been devised to solve the above problems, and provides an automobile lamp that allows light from a light source having strong linearity to be widely spread in the left-right or up-down direction, and allows light sources to be continuously arranged in the up-down or left-right direction to implement a linear beam, and has improved light source gathering efficiency.

[0015] In order to achieve the above object, the automobile lamp of the present invention comprises a light source section including a plurality of light sources arranged in a first direction; a plurality of diffusion lenses arranged in front of each of the light sources to diffuse light irradiated from the light sources and form unit beams, and a lens section in which the diffusion lenses are continuously arranged in the first direction so that the unit beams are continuously arranged and irradiated as a single linear beam; wherein the diffusion lenses are elongated in a second direction intersecting the first direction with a constant width, and have a refractive surface facing forward while being formed convexly so as to protrude forward from both width-direction edges toward the width-direction center, and a flat incident surface in the width direction facing the light sources, and wherein the lens section further comprises a light-converging means between the light sources and the diffusion lenses to condense light irradiated from the light sources onto the diffusion lenses.

[0016] It is preferable that the above light-collecting means further include a plurality of aspherical lenses arranged between the light source and the diffusion lens, and having one surface facing the diffusion lens formed as an aspherical surface to collect light irradiated from the light source.

[0017] The above-mentioned aspherical lens can be formed so that the curvature becomes smaller from the center to the edge, and a plurality of annular unit aspherical focusing parts having a larger diameter from the center to the edge can be continuously formed.

[0018] The above light-collecting means is arranged between the light source and the diffusion lens, and is formed in a cylindrical shape with an inner and outer diameter that increases from the light source to the diffusion lens. The above light-collecting means may further include a plurality of reflectors having a reflective layer formed on at least one inner surface of the inner surface facing the first direction.

[0019] The above light-collecting means further comprises a plurality of pairs of arc-shaped reflectors arranged between the light source and the diffusion lens, and a pair of the arc-shaped reflectors are arranged at an angle so that they become farther apart from each other as they move toward the diffusion lens with the light source in between, and are formed in a convex arc shape in a direction away from each other based on an optical axis from the light source to the diffusion lens, and a reflective layer may be formed on a surface facing each other.

[0020] The above diffusion lens may be formed such that the diffusion guide portion has a curvature that increases from the center of the first direction width toward both edges. In addition, the diffusion guide portion may be recessed forward so as to have an arc-shaped curvature in the first direction, but may have a constant width in the first direction and may extend in length in the second direction, and may include a plurality of unit diffusion surfaces that are continuously arranged in an arc shape in the first direction, and the plurality of unit diffusion surfaces may be formed such that the curvature increases as they get farther away from the optical axis that faces the diffusion lens from the light source.

[0021] The above diffusion lens may further have a refraction groove formed such that the width becomes narrower as it moves from the incident surface toward the refracting surface, but the end surface in the direction of introduction is formed convexly toward the light source.

[0022] In addition, the automobile lamp of the present invention may further include a plurality of light-emitting units each including the light source unit and the lens unit; and a support block formed such that a plurality of mounting surfaces on which the light-emitting units are mounted are arranged in the first direction and positioned so as to move farther forward or backward from one side in the length direction to the other side.

[0023] The automobile lamp of the present invention forms a unit beam that is elongated in the direction in which the light sources are arranged by irradiating light from a plurality of light sources, thereby forming a linear beam with a relatively small structure, thereby improving space efficiency.

[0024] In addition, the automobile lamp of the present invention can irradiate a highly efficient linear beam because the light irradiated from each light source is collected by a spherical lens and then passes through a diffusion lens to be formed into a unit beam.

[0025] Alternatively, the automobile lamp of the present invention can reflect light irradiated laterally from each light source in the direction of a diffusion lens, thereby having the advantage of being able to irradiate a high-efficiency linear beam formed from a plurality of unit beams.

[0033] Hereinafter, a lamp unit for an automobile according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0034] Figures 1 to 3 illustrate an automobile lamp (1) according to a first embodiment of the present invention.

[0035] A lamp (1) for an automobile according to a first embodiment of the present invention comprises a light source unit (10) including a plurality of light sources (11) arranged in a first direction; a light collecting means including a plurality of aspherical lenses (21) arranged in front of each light source (11) and having one surface facing away from the light source (10) formed as an aspherical surface (22) to collect light irradiated from the light source (10); and a lens unit (20) including a plurality of diffusion lenses (31) arranged in front of each aspherical lens (20) and arranged in the first direction.

[0036] The light source (11) is an LED lamp (light emitting diode lamp) and may include R, G, B LED elements for emitting single-color or multi-color light.

[0037] The first direction may be a horizontal direction, or a vertical direction orthogonal to the horizontal direction. In addition, the first direction may be a linear direction, or a circumferential direction having an arc-shaped curvature. That is, the plurality of light sources (11) arranged in the first direction may be spaced apart at regular intervals in a straight line, or spaced apart at regular intervals in the circumferential direction.

[0038] A plurality of aspherical lenses (21) have a smooth surface (28) facing the light source (11), and a front-facing surface (22) corresponding to this is formed as an aspherical surface.

[0039] The diffusion lens (31) is positioned in front of the aspherical lens (21), has a constant width in a first direction, and is formed to extend long in a second direction orthogonal to the first direction. The diffusion lens (31) is positioned in front of the aspherical lens (21) so that the width center is located on an extension line connecting the center of the aspherical lens (21) and the center of the light source (11).

[0040] Each diffusion lens (31) is placed in front of each of the aspherical lenses (21) to diffuse the light irradiated from the light sources (11) and form it into a unit beam (35).

[0041] A plurality of diffusion lenses (31) are arranged in a continuous manner in the first direction so that the unit beams (35) are arranged in a continuous manner and irradiated as a single linear beam.

[0042] The diffusion lens (31) has a refractive surface (32) that is formed convexly so as to protrude forward from both width-direction edges toward the center in the width direction and faces forward, and a concave entrance surface (34) that is flat in the width direction and faces the light source, but whose center in the second direction is positioned forward of both sides.

[0043] The aspheric lens (21) and the diffusing lens (31) can be made of transparent polycarbonate (PC: poly-carbonate) material.

[0044] The diffusing lens (21) can focus the light irradiated from the light source (11) onto the diffusing lens (31).

[0045] One side (22) of the aspherical lens (21), i.e., the aspherical surface, is formed so that the curvature decreases from the center to the edge, and unit curvature-forming surfaces (26) having different slopes or curvatures can be continuously arranged along a vertical line of the center of the smooth surface of the aspherical lens (21) from the center of the aspherical surface to the edge, i.e., a line (l) connecting the center of the aspherical lens (21) and the center of the diffusion lens (31).

[0046] Specifically, the aspherical surface (22) of the aspherical lens (21) is formed by a continuous series of a plurality of annular unit aspherical focusing parts (24) whose diameters increase from the center to the edge.

[0047] The unit spherical focusing part (24) is formed by continuously arranging a number of unit curvature forming surfaces (26) along the circumferential direction.

[0048] The unit curvature forming surfaces (26) of different unit aspherical focusing parts (24) have different slopes or curvatures with respect to the extension line (l) connecting the center of the aspherical lens (21) and the center of the diffusing lens (31), so that the curvature of the aspherical surface (21) becomes smaller from the center to the edge.

[0049] The center of the above-mentioned diffusion lens (31) refers to the center in the width direction and the length direction. In addition, the extension line (l) connecting the center of the aspherical lens (21) and the center of the diffusion lens (31) passes through the center of the light source (11).

[0050] That is, the slope or curvature of each unit curvature-forming surface (26) of the unit aspherical focusing parts (24) allows the light irradiated around the optical axis line passing through the center of the aspherical lens (21) (the extended line connecting the center of the aspherical lens (21) and the center of the diffusing lens (31)) (l) to be directed toward the optical axis line at a desired distance in front of the aspherical lens (21), so that the light can be focused to a long distance.

[0051] To this end, it is preferable that the slope or curvature of each unit curvature-forming surface (26) of the unit aspherical focusing parts (24) be formed so that the spherical aberration or the refraction angle gradually decreases as the distance from the center of the aspherical surface (22) increases.

[0052] By focusing the light irradiated from the light source (11) toward the front center of the aspherical lens (11) by these unit aspherical focusing parts (24), the focusing density can be increased to form a core light (29) having a predetermined radius.

[0053] Referring to FIGS. 2 and 3, the core light (29) passing through the aspherical lens (21) is formed into one unit beam (35) while passing through the incident surface (34) and the refracting surface (32) of the diffusion lens (31).

[0054] Referring to Fig. 2, the unit beam (35) can form a dense light distribution pattern centered on the center of the refracting surface (32) of the diffusion lens (31) and, at the same time, form a light distribution pattern that spreads out in the first direction as it moves away from the center. In addition, referring to Fig. 3, the core light (29) that passed through the aspherical lens (21) can form a light halo that is spread out at a predetermined angle in the second direction as it is refracted depending on the degree to which the diffusion lens (31) is curved in the longitudinal direction.

[0055] That is, the light distribution pattern of the unit beam forms a cross-shaped light distribution pattern as described in Korean Patent Publication No. 10-0978017, but a more concentrated light distribution pattern can be formed by the aspherical lens (21) placed between the light source (11) and the diffusion lens (31).

[0056] Meanwhile, the automobile lamp (1) according to the first embodiment of the present invention may be provided with a support block mounted on the frame of the vehicle, which supports a plurality of light sources (11), a plurality of aspherical lenses (21), and a plurality of diffusion lenses (31), although not shown, and a heat dissipation unit mounted on the support block so as to be positioned at the rear of the light sources (11).

[0057] The structure of the support block and the heat dissipation unit is not limited as long as it can support a plurality of light sources (11), a plurality of aspherical lenses (21), and a plurality of diffusion lenses (31), and can dissipate heat generated from the light sources (11).

[0058] Up to now, the automobile lamp (1) according to the first embodiment of the present invention is formed by forming light emitted from each of a plurality of light sources (11) into a unit beam (35) that is elongated in the direction in which the light sources (11) are arranged through a spherical lens and a diffusion lens, thereby forming a linear beam (36) with a relatively small structure, so that space efficiency can be improved.

[0059] In addition, the automobile lamp (1) according to the first embodiment of the present invention can irradiate a high-efficiency linear beam (36) because the light irradiated from each light source (11) is condensed by a spherical lens and then passes through a diffusion lens to be formed into a unit beam (35).

[0060] Meanwhile, Fig. 4 illustrates an automobile lamp (1') according to a second embodiment of the present invention. Components having the same function as those in the previously illustrated drawing are indicated by the same reference numerals.

[0061] An automobile lamp (1') according to a second embodiment of the present invention comprises a light source unit (10), a plurality of light emitting units (9) each including a diffusion lens (31) and a lens unit (120) including a light collection means, and a support block (40) on which a plurality of light emitting units (9) are mounted.

[0062] The lens section (120) of the light-emitting unit (9) is arranged in a first direction and formed integrally, and further comprises a pair of lens support sections (138) extending in parallel from one end or the other end of the diffusion lenses (31) located at the edge side among a plurality of diffusion lenses (31) formed integrally, toward the support block (40), and a base section (139) that is mounted on the mounting surface (41) of the support block (40) described later, connects the pair of lens support sections (138), and has a central side formed through to allow light irradiated from the light source (11) to pass through.

[0063] A plurality of diffusion lenses (31) are connected to each other as a single unit, but may also have a structure that can be mutually combined and separated.

[0064] The above light-collecting means is arranged between the light source (11) and the diffusion lens (31), and is formed in a cylindrical shape with the inner and outer diameters increasing from the light source (11) to the diffusion lens (31), and has a reflective part (140) including a plurality of reflectors (141) having a reflective layer (142) formed on the inner surface.

[0065] The reflector (141) can be mounted on the base (139) of the lens (120) so as to be arranged around the light source.

[0066] The reflective layer (142) may be formed only on the inner surfaces of both sides facing the first direction among the inner surfaces of the reflector (141), or may be formed on the entire inner surface of the reflector (141). The reflector (141) is formed so that light incident on the reflective layer (142) is reflected to the incident surface (34) of the diffusion lens (31).

[0067] The support block (40) is formed in a step shape so that a plurality of mounting surfaces (41) on which each light emitting unit (9) is mounted are arranged in the first direction, but are positioned further forward or backward from one side in the length direction to the other side.

[0068] A support block (40) is provided with a plurality of connecting surfaces (42) extending in a direction perpendicular to the mounting surfaces (41) between a plurality of mounting surfaces (41) and connecting adjacent mounting surfaces (41). Each connecting surface (42) connects one end of one mounting surface (41) to the other end of another mounting surface (41). The plurality of connecting surfaces (42) are arranged in the front-back direction, but are arranged to be offset from each other in the first or second direction.

[0069] Referring to Fig. 4, light irradiated from a light source (11) passes through a diffusion guide unit (34) of a diffusion lens (31) and is irradiated as a unit beam (35') formed long in the first direction.

[0070] The automobile lamp (1') according to the second embodiment of the present invention can improve light collection efficiency because light incident on the reflector (141) is reflected by the diffusion lens (31).

[0071] Meanwhile, FIG. 5 illustrates an automobile lamp according to a third embodiment of the present invention. Components having the same functions as those in the previously illustrated drawings are indicated by the same reference numerals.

[0072] The automobile lamp according to the third embodiment of the present invention has the same structure as the second embodiment of the present invention, except for the reflector (240).

[0073] The reflector (240), which is a light-concentrating means of an automobile lamp according to the third embodiment of the present invention, is provided with a plurality of pairs of arc-shaped reflectors (241) arranged at an angle so that they become farther apart from each other as they move toward the diffusion lens, with the light source (11) between them, respectively, between the light source (11) and the diffusion lens.

[0074] A pair of arc-shaped reflectors (241) facing each other with a light source (11) between them are formed in a convex arc shape in a direction away from each other based on the optical axis from the light source (11) toward the diffusion lens (31), and a reflective layer (242) is formed on each of the surfaces facing each other.

[0075] Meanwhile, FIG. 6 illustrates a portion of an automobile lamp according to a fourth embodiment of the present invention.

[0076] The automobile lamp according to the fourth embodiment of the present invention has the same structure as the first to third embodiments of the present invention, except for the diffusion lens (331).

[0077] The diffusion lens (331) is introduced so that its width becomes narrower from the incident surface (34) toward the refracting surface (32), and further includes a refracting groove (335) whose end surface (335a) in the introduced direction is formed convexly toward the light source (11).

[0078] Referring to Fig. 6, light that is focused by the aspherical lens (21) and is incident on the end face (335a) is refracted toward the center of the width of the diffusion lens (331), and light that is incident on the side face (335b) forming the refractive groove (335) is refracted toward the edge of the width of the diffusion lens (331).

[0079] In the automobile lamp according to the fourth embodiment of the present invention, a refraction groove (335) is formed on the incident surface (34) side of the diffusion lens (331), so that the light is concentrated at the center of the width of the diffusion lens (331), while at the same time, the light spreads out more widely as it gets farther from the center of the width, thereby increasing the efficiency of forming a light distribution pattern.

[0080] Meanwhile, FIG. 7 illustrates a portion of an automobile lamp according to a fifth embodiment of the present invention.

[0081] An automobile lamp according to a fifth embodiment of the present invention has the same structure as the first to third embodiments of the present invention, except for the refractive surface (432) of the diffusion lens (431).

[0082] The diffusion lens (431) has a refractive surface (432) that has a constant width in the first direction and extends in the second direction, and has a plurality of unit diffusion parts (433) that are continuously arranged in an arc shape in the first direction.

[0083] A plurality of unit diffusion parts (433) are arranged to have a smaller curvature the farther away they are from the center of the width of the diffusion lens (431).

[0084] In addition, the unit diffusion section (433) has a plurality of unit diffusion surfaces (435) continuously arranged in an arc-shaped curvature in the second direction.

[0085] Among the plurality of unit diffusion sections (433), the plurality of unit diffusion surfaces (435) of the unit diffusion sections (433) arranged on both sides with respect to the optical axis (a) (see FIG. 5) irradiated from the light source (11) have a slope or curvature such that the closer they get to the longitudinal center of the diffusion lens (431), i.e., on both sides in the second direction, the farther away they are from the width center of the diffusion lens (431).

[0086] Meanwhile, although not illustrated, the automobile lamps according to the sixth and seventh embodiments of the present invention have the same structure as the first embodiment of the present invention, except for the aspheric lens. Components having the same function as those in the previously illustrated drawings are indicated with the same reference numerals.

[0087] A non-convex lens according to a sixth embodiment of the present invention has the same structure as the first embodiment of the present invention, but can be formed to focus a light source so that the core light (not shown) has a wider width in the first direction than in the second direction.

[0088] Specifically, among the multiple unit curvature-forming surfaces (26) forming one unit aspherical focusing section (24), the unit curvature-forming surfaces (26) arranged on both sides in the second direction with respect to the center of the aspherical lens have a greater inclination with respect to the other surface (28) of the aspherical lens than the unit curvature-forming surfaces (26) arranged on both sides in the first direction with respect to the center of the aspherical lens, but can be formed with a large curvature.

[0089] Meanwhile, the aspherical lens according to the seventh embodiment of the present invention also has the same structure as the first embodiment of the present invention, but is formed so that the light source can be focused so that the core light (not shown) has a larger width in the first direction than in the second direction.

[0090] Specifically, each unit aspherical focusing part (24) of the aspherical lens according to the seventh embodiment of the present invention can be formed in an elliptical shape having a longer diameter in the first direction than in the second direction.

[0091] While the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible. Accordingly, the true scope of protection of the present invention should be defined solely by the appended claims.
