Description

Headlamps for mobility

[0001] The present invention relates to a headlamp for mobility, and more specifically, to a headlamp for mobility that can freely combine various beam patterns for short, medium, and long distances, perform a heat dissipation function, and provide a headlamp of various shapes by combining with other headlamps, thereby improving the design freedom of the headlamp.

[0002] A motorcycle is a type of two-wheeled vehicle that refers to a means of transportation equipped with an engine to rotate the wheels using that power, and is also called a bike, motorcycle, or motor bike.

[0003] A motorcycle is basically configured such that an engine is installed in the body to drive the wheels, and includes a headlamp to illuminate the front, a taillamp to illuminate the rear, and turn signals.

[0004] Conventional motorcycle headlamps only provide upward and downward beam patterns, and have the problem of being unable to provide illumination for long, medium, and short distances in front of the direction of travel.

[0005] In addition, conventional headlamps simply install a light source unit in the headlamp housing, and since it is difficult to provide a headlamp combined into a new form by adjusting the arrangement of the light source unit, there is a problem in that the degree of design freedom is limited.

[0007] Korean Published Patent Application No. 10-2023-0083239 (Title of Invention: Lighting Device for Motorcycle Headlamp, Date of Publication: June 9, 2023)

[0008] To solve these problems, the present invention aims to provide a mobility headlamp that can improve the design freedom of the headlamp by freely combining various beam patterns for short, medium, and long distances, performing a heat dissipation function, and providing a headlamp of various forms by combining with other headlamps.

[0009] To achieve the above-mentioned objective, one embodiment of the present invention is a headlamp for mobility, characterized by being configured to output any beam pattern and such that a plurality of coupling parts formed along the longitudinal direction on the outer surface of a housing interlock with each other with coupling parts formed on another headlamp.

[0010] In addition, the beam pattern according to the above embodiment is characterized as being one of an upward beam pattern, a downward beam pattern, a directional beam pattern, a standard beam pattern, and a wide beam pattern.

[0011] In addition, the headlamp according to the above embodiment is characterized by comprising: a housing having a storage space formed by penetrating the interior and a plurality of connecting parts protruding along the longitudinal direction on the outer surface; a light source unit installed in the housing to output light; a beam pattern forming unit that controls the light output from the light source unit to be output as an arbitrary beam pattern; a circuit unit that controls the operation of the light source unit and the operation of the beam pattern forming unit; and a heat sink that absorbs and emits heat generated from the light source unit, while conducting a portion of the absorbed heat to the housing.

[0012] In addition, the coupling portion according to the above embodiment is characterized by operating as a heat dissipation fin that releases heat conducted from the heat sink.

[0013] In addition, the coupling portion according to the above embodiment is characterized by being formed with coupling protrusions of the same shape on the upper, lower, left, and right sides of the housing.

[0014] In addition, the coupling portion according to the above embodiment is characterized in that coupling protrusions of the same shape are formed on the upper and lower sides of the housing, and coupling protrusions of a different shape are formed on the left and right sides of the housing.

[0015] In addition, the shape of the housing according to the above embodiment is characterized by being a prism shape composed of polygons that are parallel to each other and congruent.

[0016] In addition, the beam pattern forming unit according to the above embodiment includes a first optical system for concentrating light output from the light source unit; and a second optical system for dispersing and outputting the light concentrated by the first optical system; wherein the first optical system and the second optical system are configured such that the light output from the light source unit forms and outputs one of a beam pattern, a standard beam pattern, and a wide beam pattern.

[0017] In addition, the beam pattern forming unit according to the above embodiment is characterized by further including a cutoff shield unit installed between the first optical system and the second optical system, which operates to selectively block a portion of the light output from the first optical system to form an upward beam pattern or a downward beam pattern.

[0018] The present invention has the advantage of improving the design freedom of headlamps by allowing various beam patterns to be freely combined for short, medium, and long distances, performing a heat dissipation function, and providing headlamps of various shapes by combining with other headlamps.

[0019] In addition, the present invention has the advantage that the interlocked headlamps are firmly fixed to each other, thereby increasing resistance to shaking or vibration and reducing light flickering caused by road vibrations while driving.

[0020] In addition, the present invention has the advantage of allowing easy installation and replacement through an interlocking coupling structure, and easy setting of the illumination angle and alignment of light output from individual headlamps through the interlocking coupling structure.

[0049] As shown in FIGS. 1 to 7, a headlamp (100) for a mobile according to one embodiment of the present invention can freely combine various beam patterns and output any beam pattern to provide various types of headlamps by combining with other headlamps while performing a heat dissipation function, and a plurality of coupling parts (111, 112) formed along the longitudinal direction on the outer surface of a housing (110) can be configured to interlock with each other with coupling parts formed on other headlamps (100a).

[0050] To this end, the headlamp (100) may be configured to include a housing (110), a light source unit (120), a beam pattern forming unit (130), a control circuit unit (140), and a heat sink (150), wherein the mobility may be a means of transportation using one or more wheels.

[0051] Additionally, the headlamp (100) may be configured to include a cable (160) for connecting to an external control device as in FIG. 3(a), and may also be configured to be connected via a connector (170) as in FIG. 3(b).

[0052] The housing (110) may be composed of a tube with a storage space formed through the interior, and may be composed of a prism-shaped member having two sides that are parallel to each other and congruent polygons.

[0053] Additionally, the housing (110) may have a first connecting part (111) and a second connecting part (112) protruding along the longitudinal direction on its outer surface, and the housing (110), the first connecting part (111), and the second connecting part (112) may be formed through extrusion molding.

[0054] Additionally, the housing (110) may be composed of aluminum, an aluminum alloy, or a metal material capable of performing a heat dissipation function together with the first coupling part (111) and the second coupling part (112).

[0055] The first coupling part (111) and the second coupling part (112) can be installed symmetrically on the upper / lower and left / right sides of the outer surface of the housing (110), and the first coupling projection (111a) formed on the first coupling part (111) and the second coupling projection (112a) formed on the second coupling part (112) can operate as coupling members to engage with the first coupling projection and the second coupling projection formed on the first coupling part and the second coupling part of another headlamp (100a), respectively.

[0056] In addition, the shape of the first coupling part (111) and the second coupling part (112) is configured such that, as in FIG. 5(a), the first coupling projection (111a) of the first coupling part (111) and the second coupling projection (112a) of the second coupling part (112) are formed in a tapered shape inclined toward the outer direction of the housing (110), thereby allowing them to be coupled with the first coupling part and the second coupling part installed on another headlamp (100a), so that they can be firmly fixed.

[0057] Additionally, the shapes of the first coupling part (111) and the second coupling part (112) may be configured such that the cross-sectional shape of the first coupling projection (111a') of the first coupling part (111') and the second coupling projection (112a') of the second coupling part (112') is configured to be 'T' shaped as shown in FIG. 5(b), so as to be coupled with the first coupling part and the second coupling part installed on another headlamp.

[0058] Additionally, the shapes of the first coupling part (111) and the second coupling part (112) may be configured such that the cross-sectional shape of the first coupling projection (111a) of the first coupling part (111) and the second coupling projection (112a) of the second coupling part (112) is formed in a '『' shape as shown in FIG. 5(c), so as to be coupled with the first coupling part and the second coupling part installed on another headlamp.

[0059] In addition, as shown in FIGS. 5(a), 5(b), and 5(c), the shapes of the first and second connecting parts are configured to be installed symmetrically on the upper / lower and left / right sides of the outer surface of the housing (110), but are not limited thereto. The upper / lower sides of the housing (110) may be configured, for example, with a tapered shape as in FIG. 5(a) or a 'T' shape as in FIG. 5(b), and the left / right sides may be configured with a '『' shape as in FIG. 5c, thereby preventing incorrect assembly when combined with other headlamps and preventing the beam pattern from being mis-outputted by changing to a horizontal or vertical direction.

[0060] Additionally, the lengths of the first coupling part (111) and the second coupling part (112) can be configured to be longer than a certain length along the longitudinal direction of the housing (110) so that when the headlamp (100) and another headlamp (100a) are engaged facing each other, a double cutoff line between the headlamp (100) and another headlamp (100a) is not created due to tolerance.

[0061] For example, even if a tolerance of ± 0.1 occurs in the shape of the first joint (111) and the second joint (112) through extrusion molding, if the length of the first joint (111) and the second joint (112) is formed to be greater than a certain length, the headlamp (100) and another headlamp (100a) can be aligned in the same optical axis direction through the complex tolerance that occurs between the interlocking of the first joint (111) and the second joint (112).

[0062] This can reduce the occurrence of double cutoff lines caused by the tolerance between the headlamp (100) and another headlamp (100a).

[0063] Additionally, the first coupling part (111) and the second coupling part (112) can perform a function similar to a heat dissipation fin to release heat conducted from the heat sink (150) through the housing (11).

[0064] The light source unit (120) is configured to be installed in the housing (110) and output light, and can be composed of an LED.

[0065] The beam pattern forming unit (130) is installed in the housing (110) and is configured to control the light output from the light source unit (120) to be output as any beam pattern, and the beam pattern can form an upward beam pattern or a downward beam pattern, any one of a directional beam pattern, a standard beam pattern, and a wide beam pattern.

[0066] Here, the upward beam pattern is a beam pattern in which the direction of light output from the light source unit (120) is directed upward, and the downward beam pattern is a beam pattern in which the direction of light output from the light source unit (120) is directed downward.

[0067] A directional beam pattern is a beam pattern in which light output from a light source (120) is concentrated in a narrow area and can illuminate a distant area like a spot beam.

[0068] The wide beam pattern is a beam pattern in which light output from the light source (120) irradiates a wide area, and can irradiate a near area.

[0069] The standard beam pattern is an intermediate beam pattern that combines a directional beam pattern and a wide beam pattern, and can illuminate the mid-range area.

[0070] In other words, a directional beam pattern can be used to illuminate long distances, a standard beam pattern to illuminate medium distances, and a wide beam pattern to illuminate short distances.

[0071] To this end, as shown in FIG. 7, at least three headlamps (100) may be configured to be interlocked with each other, such as a headlamp (100) that outputs a directional beam pattern, a headlamp (100a) that outputs a standard beam pattern, and a headlamp (100b) that outputs a wide beam pattern.

[0072] The beam pattern forming unit (130) may be configured to include a first optical system (131), a second optical system (132), and a cutoff shield unit (133).

[0073] The first optical system (131) is configured to concentrate the incident light at a fixed focal length and output it when light output from the light source unit (120) is incident, and can be composed of a primary lens.

[0074] The second optical system (132) may be composed of a projection lens and installed at the end of the housing (110) to concentrate and output light output from the first optical system (131).

[0075] The first optical system (131) and the second optical system (132) can output light from the light source unit (120) by forming one of a beam pattern such as a directional beam pattern (200), a standard beam pattern (210), and a wide beam pattern (220), as shown in FIG. 8.

[0076] The cutoff shield portion (133) is installed between the first optical system (131) and the second optical system (132) and is configured to selectively block a portion of the light output from the first optical system (131) to form an upward beam pattern or a downward beam pattern, and may be configured to include a blocking portion (not shown) for blocking a portion of the output light and an actuator (not shown) for operating the blocking portion.

[0077] That is, the cutoff shield section (133) is turned on / off according to the operation control signal of the control circuit section (140), and when an operation control signal for outputting a downward beam pattern is input from the control circuit section (140), the actuator operates to form a downward beam pattern by vertically positioning the blocking section to block a portion of the light (light moving upward) moving from the first optical system (131) to the second optical system (132).

[0078] Additionally, when the cutoff shield section (133) receives an operation control signal for outputting an upward beam pattern from the control circuit section (140), the actuator folds the blocking section so that all light moving from the first optical system (131) to the second optical system (132) passes through, thereby forming an upward beam pattern.

[0079] Additionally, the cutoff shield portion (133) enables the light output from the light source portion (120) to be output as an upward beam pattern or a downward beam pattern when the light output from the light source portion (120) is output as a beam pattern among a directional beam pattern, a standard beam pattern, and a wide beam pattern through the first optical system (131) and the second optical system (132).

[0080] For example, a headlamp module is formed by combining a headlamp (100) that forms a directional beam pattern, a headlamp (100a) that forms a standard beam pattern, and a headlamp (100b) that forms a wide beam pattern. When the configured headlamp module is applied to a two-wheeled vehicle, individual cutoff shield portions (133) installed in each headlamp (100, 100a, 100b) can be operated to form a downward beam pattern and an equal illuminance pattern as shown in FIGS. 9 and FIGS. 10.

[0081] In addition, a headlamp module may be formed by combining a headlamp (100) that forms a directional beam pattern, a headlamp (100a) that forms a standard beam pattern, and a headlamp (100b) that forms a wide beam pattern. When the configured headlamp module is applied to a four-wheeled vehicle, individual cutoff shield portions (133) installed in each headlamp (100, 100a, 100b) may be operated to form a downward beam pattern and an equal illuminance pattern as shown in FIGS. 11 and FIGS. 12.

[0082] In addition, a headlamp (100) forming a directional beam pattern, a headlamp (100a) forming a standard beam pattern, and a headlamp (100b) forming a wide beam pattern are combined to form a headlamp module, and when the configured headlamp module is applied to a two-wheeled vehicle, individual cutoff shield portions (133) installed in each headlamp (100, 100a, 100b) can be operated to form an upward beam pattern and an equal illuminance pattern as shown in FIGS. 13 and 14.

[0083] In addition, a headlamp module may be formed by combining a headlamp (100) that forms a directional beam pattern, a headlamp (100a) that forms a standard beam pattern, and a headlamp (100b) that forms a wide beam pattern. When the configured headlamp module is applied to a four-wheeled vehicle, individual cutoff shield portions (133) installed in each headlamp (100, 100a, 100b) may be operated to form an upward beam pattern and an equal illuminance pattern as shown in FIGS. 15 and FIGS. 16.

[0084] The control circuit section (140) is configured to control the operation of the light source section (120) and the beam pattern forming section (130), and may be configured to include an LED driving driver for driving the light source section (120) and a control means for controlling the cutoff shield section (133).

[0085] Additionally, the control circuit section (140) can be configured to be divided into a first circuit section (141), a second circuit section (142), and a third circuit section (143) on the FPCB so that it can be efficiently placed inside the housing (110) of the barrel structure.

[0086] Additionally, the control circuit section (140) can be installed on an FPCB having an overall shape that is 'Y'-shaped, and through the bending deformation of the FPCB, the first circuit section (141) and the second circuit section (142) are positioned to be in close contact with the inner walls on both sides of the housing (110), and the third circuit section (143) is positioned to be in close contact with the heat sink (150), thereby allowing for effective placement in the narrow space of the housing (110).

[0087] In addition, by configuring the control circuit section (140) using a 'Y'-shaped FPCB so that it is fixed in close contact with both inner sides of the housing (110), rapid installation and manufacturing are possible, and a sufficient light path can be secured by the light source section (120), the first optical system (131), the second optical system (132), and the cutoff shield section (133) in the narrow space of the housing (110).

[0088] The heat sink (150) is configured to protect the light source unit (120), the beam pattern forming unit (130), and the circuit unit (140) housed in the housing (110), and to absorb and release heat generated from the light source unit (120), so that some of the absorbed heat is conducted to the housing (110) to be released more quickly.

[0089] Additionally, at least a portion of the heat sink (150) is in close contact with the housing (110) to conduct heat generated from the light source (120) to the housing (110), and a lubricant (thermal grease) may be applied between the light source (120) and the heat sink (150), and between the heat sink (150) and the housing (110) for effective heat transfer.

[0090] Meanwhile, a mobility headlamp according to one embodiment of the present invention can be configured by combining a plurality of headlamps (100, 100a, 100b, 100c, 100d) in various forms according to the user's needs, as shown in FIGS. 17 and 18.

[0091] In addition, in the embodiment of the present invention, the cross-sectional shape of the headlamp (100) is described as a square headlamp (100), but it is not limited thereto, and as shown in FIG. 19, the headlamp (100', 100'a) may be combined to form a prism with a triangular cross-sectional shape.

[0092] In addition, as shown in FIG. 20, a headlamp (100", 100"a) made of a prism with a cross-sectional shape in the shape of a rhombus and a headlamp (100', 100'a) made of a prism with a cross-sectional shape in the shape of a triangle may be combined.

[0093] Therefore, various beam patterns can be freely combined for short, medium, and long distances, and the design freedom of the headlamp can be improved by providing various types of headlamps through combination with other headlamps while performing heat dissipation functions.

[0094] In addition, the interlocking headlamps are firmly fixed to each other, increasing resistance to shaking or vibration, which can reduce light flickering caused by road vibrations while driving.

[0095] In addition, the interlocking coupling structure allows for easy installation and replacement, and the illumination angle and alignment of the light output from individual headlamps can be easily set.

[0096] As described above, although the present invention has been explained with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the invention as described in the following claims.

[0097] In addition, the drawing numbers described in the claims of the present invention are provided for clarity and convenience of explanation only and are not limited thereto, and in the process of describing the embodiments, the thickness of lines or the size of components shown in the drawings may be exaggerated for clarity and convenience of explanation.

[0098] Furthermore, the terms described above are defined in consideration of their functions in the present invention, and since these may vary depending on the intentions or practices of the user or operator, the interpretation of these terms should be based on the content throughout this specification.
