Description

Field of the invention

[0001] The various embodiments of the present invention each relate to a headlight, in particular a headlight for a two-wheeler, which can be attached to the two-wheeler, such as a bicycle. State of the art

[0002] Two-wheeled vehicles (e.g., bicycles, scooters, and motorcycles) have established themselves as both common means of transportation and popular tools for recreational activities. Mobility devices such as electric bicycles, electric scooters, and electric kickboards, which are powered by electric propulsion, have also established themselves as alternative means of transportation. They are not only environmentally friendly, as they do not emit pollutants, but can also solve serious traffic congestion and parking problems.

[0003] If a user uses such a two-wheeler or mobility device at night or during the day in cloudy weather, a headlight shall be attached to the two-wheeler or mobility device by means of a connecting device such as a retaining clip to prevent an accident caused by the user's negligence.

[0004] Generally, the headlight consists of a high-efficiency LED element and a substrate on which the LED element is mounted, but there is a problem that the performance of the headlight would be affected due to the temperature increase of the LED element and substrate.

[0005] DE 20 2012 005 209 U1 discloses a bicycle lamp comprising a housing with a circuit board mounted in the housing, provided with an LED, wherein the circuit board is configured to form a heat sink of the LED, wherein the housing is provided with an air inlet for supplying ambient air to the circuit board and an air outlet for discharging air supplied to the circuit board to the environment.

[0006] DE 10 2012 010 103 A1 discloses a bicycle headlight with a light-emitting diode, which comprises a central carrier made of thermally conductive material, to which the light-emitting diode is thermally connected, and a holder which is thermally connected to the central carrier so that it can dissipate the waste heat of the headlight to the environment. Disclosure of the invention

[0007] Therefore, the invention was filed to solve the above-mentioned problems, and the object of the invention is to provide a headlight for a two-wheeler which can prevent the deterioration of the luminous efficiency due to heat deterioration.

[0008] The object is achieved by the subject matter of the independent claim. Advantageous embodiments are defined in the dependent claims.

[0009] A headlight for a two-wheeler according to an embodiment of the present disclosure is one that is connected to a bracket of the two-wheeler, the headlight comprising a housing; a first substrate installed within the housing and on which a light emitting unit for emitting a light is mounted; and at least one bracket connection connected to the housing, detachably coupled to the bracket, and disposed adjacent to the first substrate.

[0010] Furthermore, it can be provided that the at least one retaining clip connection has at least one support extending from the housing; and at least one coupling that couples the at least one support to the retaining clip.

[0011] It can be provided that a thread is formed on the at least one coupling, while a threaded hole corresponding to the thread is introduced into the at least one support, wherein the at least one coupling can be screwed to the at least one support.

[0012] A retaining clip recess is provided in the housing to accommodate part of the retaining clip.

[0013] Furthermore, it can be provided that the headlight for a two-wheeler additionally comprises a sealing part for closing the at least one retaining clip recess.

[0014] The headlight for a two-wheeler also includes a lens that is mounted inside the housing and has an inclined surface.

[0015] The at least one retaining clip connection is arranged between the lens and the first substrate.

[0016] It can be provided that the at least one retaining clip connection has a first retaining clip connecting section which is arranged between the inclined surface of the lens and one side of the first substrate, and a second retaining clip connecting section which is also arranged between the inclined surface of the lens and one side of the first substrate, wherein the second retaining clip connecting section is arranged opposite the first retaining clip connecting section such that the light emitting unit is located between the two connecting sections.

[0017] In addition, it can be provided that the first retaining clip connecting section is detachably coupled to the retaining clip of the two-wheeler, while the second retaining clip connecting section is detachably coupled to the retaining clip or to another, second retaining clip.

[0018] It can be provided that the material of the at least one retaining clip connection is selected from the group consisting of aluminum, aluminum alloys, copper, copper alloys and combinations thereof.

[0019] Furthermore, it can be provided that the at least one retaining clip connection comes into contact with the first substrate.

[0020] In addition, it can be provided that the material of the first substrate is a metal.

[0021] Furthermore, it can be provided that the headlight for a two-wheeler additionally comprises a second substrate to which the electronic components are attached, which drives the light-emitting unit in such a way that the latter emits the light, wherein the second substrate is arranged opposite the retaining clip connection in such a way that the first substrate lies between the retaining clip connection and the second substrate. Effects of the invention

[0022] According to the embodiments of the present invention, a heat radiation performance of the headlight is improved because the heat caused by a light emitting unit is effectively radiated to the outside through a retaining clip connection.

[0023] Since the heat radiation performance can be increased without increasing the size of the headlight, it is also possible to miniaturize the headlight.

[0024] Since the retaining clip connection does not protrude outwards from the housing, it is also possible to implement a refined design of the headlight. Short description of the drawings

Preferred embodiments of the present disclosure

[0026] Below, various embodiments of the present disclosure will be explained in more detail with reference to the accompanying drawings. However, it will be clear to a person skilled in the art that the accompanying drawings are merely illustrative of a content of the present disclosure to facilitate disclosure, and the scope of the present disclosure should not be limited to the scope of the accompanying drawings.

[0027] With regard to the explanation of the various embodiments of the present disclosure, it should be clarified in advance that only the same designations and reference numerals are used for the components with the same function, such components not being substantially identical to those of a conventional headlight.

[0028] In addition, the terms used in the various embodiments of the present disclosure are used only to explain a particular embodiment, but are not intended to limit the disclosure. The singular expressions also include the plural meanings, unless the context clearly indicates otherwise. In the various embodiments of the present disclosure, the terms, such asThe use of terms such as "comprise", "include", "have" or the like in this description only indicates that features, digits, steps, movements, components, parts or items comprising them are described and present in this description, but the presence or addition of one or more other features, digits, steps, movements, components, parts or items combined from these should be understood as not previously excluded.

[0029] Fig. 1 shows a side view of a headlight for a two-wheeler according to an embodiment of the present disclosure and Fig. 2 shows a sectional view of a headlight for a two-wheeler according to an embodiment of the present disclosure.

[0030] With reference to Fig. 1 and Fig. 2, it can be provided that the headlight for a two-wheeler according to one exemplary embodiment of the disclosure is connected to a retaining clip 120 of the two-wheeler and has a housing 110, a first substrate 160, a second substrate 170, a lens 162, and at least one retaining clip connection 130 or 150. The two-wheeler can be a bicycle, motor scooter, or motorcycle, or a means of mobility, such as an electric bicycle, electric scooter, electric motorcycle, or electric kickboard, and also various means of transport or movement.

[0031] The headlight for a bicycle according to one embodiment of the present disclosure can be attached to the bicycle by means of the retaining bracket 120. One end 121 of the retaining bracket 120 can be connected to the headlight 100 for a bicycle, while another end 122 of the retaining bracket 120 can be connected to the bicycle. A first attachment hole 123 and a second attachment hole 124 can be formed in the other end 122 of the retaining bracket 120. At this time, a part of the bicycle can be inserted into one of the first 123 and second attachment holes 124, and a bolt (not shown) can be inserted into another of the first 123 and second attachment holes 124. Therefore, the retaining bracket 120 can be attached to the bicycle by means of the bolt connection.However, a method for attaching the retaining bracket 120 to the bicycle is not limited to the bolt connection, but various connection methods can be applied to the attachment of the retaining bracket 120 to the bicycle.

[0032] The housing 110 can accommodate the first substrate 160, the second substrate 170, the lens 162, and the at least one retaining clip connection 130 or 150, which will be discussed later. A front cover 163 is coupled to one end of the housing 110. This front cover 163 can be formed from a transparent material. A rear cover 112 (see Fig. 3) coupled.

[0033] Furthermore, the material of the housing 110 can be a metal. For example, the material of the housing 110 can be selected from the group consisting of copper, copper alloys, aluminum, aluminum alloys, and combinations thereof. However, the material of the housing 110 should not be limited to metal; in particular, it can also be a plastic with thermal conductivity.

[0034] At least one retaining clip recess for receiving a part of the retaining clip 120 can be introduced into the housing 110. The at least one retaining clip recess can have a first retaining clip recess 131b and a second retaining clip recess 151b ( Fig. 4). Furthermore, the first retaining clip recess 131b may be arranged above the housing 110, while the second retaining clip recess 151b ( Fig. 4) can be arranged below the housing 110.

[0035] Furthermore, the first substrate 160 is installed within the housing 110. In addition, a light emitting unit 161 for emitting light is mounted on one side 160a of the first substrate 160.

[0036] The light-emitting unit 161 may be composed of an LED (light-emitting diode) element. However, the structure of the light-emitting unit 161 should not be limited to the LED element; in particular, the light-emitting unit may be composed of various elements capable of emitting light.

[0037] Furthermore, the second substrate 170 can be arranged at a distance from the first substrate 160. Electronic components (not shown) that drive the light-emitting unit 161 to emit light can be mounted on this second substrate 170. One of the electronic components can be, for example, a power supply unit for supplying the light-emitting unit 161 with electrical energy. This power supply unit can be electrically connected to a battery (not shown) that stores the electrical energy. This power supply unit can also be various devices that are supplied with electrical energy from the exterior of the housing 110 and then supply this energy to the light-emitting unit 161.The light-emitting unit 161 can be electrically connected to the power supply unit mounted on the second substrate 170 and thus be supplied with electrical energy by this power supply unit so that it can emit the light. Such electrical components can also be a processor for regulating the light emitted by the light-emitting unit 161, a communication module, or any type of sensor.

[0038] In addition, the lens 162 is mounted within the housing 110. The light generated by the light-emitting unit 161 can be emitted from the housing 110 to the outside through the lens 162.

[0039] The cross-sectional size of the lens 162 can be widened in the propagation direction of the light emitted by the light-emitting unit 161. This means that the lens 162 can, for example, have a conical shape. Furthermore, the lens 162 can be provided with an inclined surface 162a or 162b. The inclined surface 162a or 162b can comprise a first inclined surface 162a and a second inclined surface 162b. Therefore, the lens 162 provided with the inclined surface 162a or 162b can collect the light generated by the light-emitting unit 161 and thus form it into a specific light distribution shape.

[0040] Further, the lens 162 may be configured such that, if the light emitted from the light emitting unit 161 is irradiated outward from the housing 110, the light irradiated outward and upward from the housing 110 and the light irradiated outward and downward from the housing 110 are different from each other.

[0041] After the retaining bracket 120 is connected to the first retaining bracket connecting portion 130 via the first retaining bracket recess 131b, the light distribution shape of the bicycle headlight 100 can change depending on whether the retaining bracket is connected to a specific part of the bicycle located above the housing 110 or to a specific part of the bicycle located below the housing 110. For example, the light distribution efficiency of the bicycle headlight 100 can be higher when the retaining bracket 120 is connected to the specific part of the bicycle located below the housing 110 than when it is connected to the specific part of the bicycle located above the housing 110.

[0042] Therefore, in order to increase the light distribution efficiency of the headlight 100 for a two-wheeler, the retaining bracket 120 may be connected to the second retaining bracket connecting portion 150 via the second retaining bracket recess 151b of the housing 110. Here, the connection structure in which the retaining bracket is connected to the second retaining bracket connecting portion 150 should not be limited to the retaining bracket 120, but the connection structure may be various connecting devices such as a second retaining bracket to be mentioned later.

[0043] Furthermore, the at least one retaining clip connection 130 or 150 may be connected to the housing 110, releasably coupled to the retaining clip 120, and arranged adjacent to the first substrate 160. Furthermore, the at least one retaining clip connection 130 or 150 may include at least one support 131 or 151 extending from the housing 110; and at least one coupling 132 coupling the at least one support 131 or 151 to the retaining clip 120.

[0044] Furthermore, the at least one retaining clip connection 130 or 150 can have a first retaining clip connecting portion 130 and a second retaining clip connecting portion 150. The first retaining clip connecting portion 130 can be received in the first retaining clip recess 131b, while the second retaining clip connecting portion 150 can be received in the second retaining clip recess 151b (see Fig. 4). Due to the fact that the first 130 and the second retaining clip connecting section 150 are arranged in the first 131b and the second retaining clip recess 151b (see Fig. 4), the first 130 and the second retaining clip connecting portion 150 cannot protrude outwardly from the housing 110 and thus be embedded within the housing 110.

[0045] The first retaining clip connecting section 130 may have a first support 131 and a second coupling 132.

[0046] In addition, the first support 131 may extend from the housing 110.

[0047] Furthermore, the material of the first support 131 can be selected from the group consisting of copper, copper alloys, aluminum, and aluminum alloys, and various materials with high thermal conductivity can also be used. The first support 131 can be brought into contact with the first substrate 160.

[0048] Furthermore, the first coupling 132 can be a bolt with a thread formed thereon. A first threaded hole (not shown) corresponding to the thread can be provided in the first support 131. A first hole (not shown) corresponding to the first threaded hole can be provided in one end 121 of the retaining clip 120. When the first coupling 132 is inserted into the first hole of the retaining clip 120 and then screwed into the first threaded hole, the first coupling 132 is fastened to the first support 131. One end 121 of the retaining clip 120 is then rotatably coupled to the first coupling 132.

[0049] By emitting light, the light-emitting unit 161 also generates heat. The heat generated by the light-emitting unit 161 may be transferred to the first substrate 160. The heat transferred to the first substrate 160 is then transferred to the first support 131 in contact with the first substrate 160. Furthermore, the heat transferred to the first support 131 is also transferred to the first coupling 132 connected to the first support 131. In turn, the heat transferred to the first coupling 132 is also transferred to one end 121 of the retaining clip 120. Then, the heat transferred to one end 121 of the retaining clip 120 is also transferred to another end 122 of the retaining clip 120. Finally, the heat transferred to the other end 122 of the retaining clip 120 may be transferred to the bicycle.

[0050] Since the first retaining clip connecting portion 130 is disposed adjacent to the first substrate 160 in this manner, according to one embodiment of the present disclosure, the heat caused by the light emitting unit 161 is smoothly released to the outside of the housing 110.

[0051] Furthermore, the first retaining clip recess 131b may be disposed between the first inclined surface 162a of the lens 162 and the first substrate 160. Thus, the first retaining clip connecting portion 130 connected to the retaining clip 120 via the first retaining clip recess 131b does not protrude outward from the housing 110, so that the design of the headlight 100 for a two-wheeler can be refined.

[0052] In addition, the second substrate 170 and the battery are arranged opposite to the first retaining clip connecting portion 130 such that the first substrate 160 is sandwiched between the first retaining clip connecting portion and the second substrate or the battery, and since the heat caused by the light emitting unit 161 is transferred to the first retaining clip connecting portion 130, the heat caused by the light emitting unit 161 is prevented from being transferred to the second substrate 170 or the battery.

[0053] In addition, the thermal conductivity of the material of the first retaining clip connecting portion 130 may be different from that of the material of the first substrate 160. For example, the thermal conductivity of the material of the first retaining clip connecting portion 130 may be higher than that of the material of the first substrate 160. Therefore, the heat transferred to the first substrate 160 can be prevented from moving beyond the first retaining clip connecting portion 130 into the second substrate 170 or the battery.

[0054] Furthermore, the second retaining clip connecting portion 150 may include a second support 151. This second support 151 may extend from the housing 110.

[0055] Thus, the second support 151 can be arranged opposite the first support 131 such that the lens 162 lies between the second support 151 and the first support 131.

[0056] Furthermore, the material of the second support 151 can be selected from the group consisting of copper, copper alloys, aluminum, and aluminum alloys, and various materials with high thermal conductivity can also be used. The second support 151 can be brought into contact with the first substrate 160. This second support 151 will be explained in more detail below with reference to the remaining figures.

[0057] Fig. 3 shows a perspective view of a headlight for a two-wheeler according to an embodiment of the present disclosure.

[0058] With reference to Fig. 3, the headlight 100 for a two-wheeler according to the one embodiment of the present disclosure may include at least one sealing part.

[0059] The at least one sealing part may have a first sealing section 135 (see Fig. 4) and a second sealing section 155. This first sealing section is explained below with reference to the remaining figures.

[0060] The second sealing section 155 can form the second retaining clip recess 151b (see Fig. 4). Thus, the second sealing section 155 prevents a foreign body from passing through the second retaining clip recess 151b (see Fig. 4) enters the interior of the housing 110.

[0061] Fig. 4 shows a perspective view of a headlight for a two-wheeler according to an embodiment of the present disclosure in a state in which a second retaining bracket is connected to the headlight.

[0062] With reference to Fig. 4, the second retaining clip connecting portion 150 may include a second coupling 152.

[0063] Furthermore, the second coupling 152 can be a bolt with a thread formed thereon. In the second support 151 (see Fig. 1) a second threaded hole 151a corresponding to the thread (see Fig. 2). In one end 180a of a second retaining clip 180, a second threaded hole 151a (see Fig. 2) corresponding second hole (not shown). If the second coupling 152 is inserted into the second hole of the second retaining clip 180 and then screwed into the second threaded hole, the second coupling 152 is connected to the second support 151 (see Fig. 1). Now, one end 180a of the second retaining clip 180 is rotatably coupled to the second coupling 152.

[0064] In contrast, a fastening hole 181a can be provided in another end of the second retaining clip 180. The fastening hole 181a can serve as a means for connecting to a device used on the bicycle, such as the bicycle's reflector.

[0065] Furthermore, the second retaining clip recess 151b can be arranged between the second inclined surface 162b (see Fig. 2) the lens 162 (see Fig. 2) and the first substrate 160 (see Fig. 2). Thus, the second retaining clip connecting portion 150 connected to the second retaining clip 180 via this retaining clip recess 151b does not protrude outward from the housing 110, so that the design of the headlight 100 for a two-wheeler can be refined.

[0066] When the first retaining clip connecting portion 130 is separated from the retaining clip 120 (see Fig. 3), then the first retaining clip recess 131b (see Fig. 3) from the housing 110 to the outside. The first sealing section 135 can form the first retaining clip recess 131b (see Fig. 3). Thus, the first sealing section 135 prevents a foreign body from passing through the first retaining clip recess 131b (see Fig. 3) enters the interior of the housing 110.

[0067] Fig. 5 shows a sectional view of a headlight for a two-wheeler according to another embodiment of the present disclosure.

[0068] With reference to Fig. 5, the headlight 200 for a two-wheeler according to the further embodiment of the present disclosure can be connected to a retaining clip 220 of a two-wheeler, wherein it can also have a housing 210, a first substrate 260, a second substrate 270, a lens 262 and at least one retaining clip connection 230 or 250.

[0069] Here, a front cover 163 is coupled to one end of the housing 210, while a rear cover 212 is coupled to another end of the housing 210. Furthermore, the light-emitting unit 161 can be mounted on one side 260a of the first substrate 160. The lens 262 can be provided with a first inclined surface 262a and a second inclined surface 262b. In this regard, the explanations of the components identical or similar to those of this embodiment will be replaced by the explanations described above.

[0070] The at least one retaining clip connection 230 or 250 can be arranged between the lens 262 and the first substrate 260. Furthermore, the at least one retaining clip connection 230 or 250 can have a first retaining clip connection section 230 and a second retaining clip connection section 250.

[0071] Furthermore, the first retaining clip connecting portion 230 may include a first support 231 and a first coupling 232. A part of the first retaining clip connecting portion 230 may be arranged to overlap a first region 233 between the first inclined surface 262a of the lens 262 and the one side 260a of the first substrate 260.

[0072] The first region 233 may represent the region in which the temperature within the housing 210 is relatively high due to the heat generated by the light emitting unit 261.

[0073] By arranging one part of the first retaining clip connecting portion 230 to overlap the first region 233, the first retaining clip connecting portion 230 can transfer the heat of the first region 233 to the retaining clip 220. That is, the first retaining clip connecting portion 230 can prevent the heat from concentrating on the first region 233.

[0074] In addition, the second retaining clip connecting portion 250 may include a second support 251. The second retaining clip connecting portion 250 may be arranged opposite the first retaining clip connecting portion 230 such that the light emitting unit 261 is located between the second retaining clip connecting portion 250 and the first retaining clip connecting portion 230. A part of the second retaining clip connecting portion 250 may be arranged to overlap a second region 253 between the second inclined surface 262b of the lens 262 and one side 260a of the first substrate 260.

[0075] The second region 253 may represent the region in which the temperature within the housing 210 is relatively high due to the heat generated by the light emitting unit 261.

[0076] By arranging one part of the second retaining clip connecting portion 250 to overlap the second region 253, the second retaining clip connecting portion 250 can transfer the heat of the second region 253 to the retaining clip 220. That is, the second retaining clip connecting portion 250 can prevent the heat from concentrating on the second region 253.

[0077] Fig. Fig. 6a is a diagram illustrating the temperature of a headlight by simulating a state in which the radiation of heat from the headlight to the outside is blocked, and Fig. 6b shows a diagram illustrating a heat flow from Fig. 6a. However, Fig. 7a is a diagram illustrating the temperature of the headlight by simulation in a state where the heat is radiated outward from the headlight, and Fig. 7b a diagram illustrating a heat flow from Fig. 7a. Finally, Fig. 8a is a diagram illustrating the temperature of a headlight by simulation in a state where the heat is radiated from the headlight to the outside through the retaining clip, and Fig. 8b a diagram illustrating a heat flow from Fig. 8a.

[0078] If it is initially on Fig. 6a, it can be seen that the temperature of a region adjacent to a heat-generating light-emitting unit within the headlamp in a state where the radiation of heat from the headlamp to the outside is blocked is approximately 60.7000 to 60.8948 °C, thus the region of the headlamp adjacent to the light-emitting unit has a high temperature.

[0079] With reference to Fig. 6b it is also evident that the heat flow is highest in an edge region of the first substrate to which the light emission unit is attached.

[0080] However, Fig. 7a the temperature of the headlight in a state in which the heat is radiated from the headlight through a retaining clip recess to the outside, whereby it can be seen here that the Fig. 7a compared to the temperature of the headlight shown in Fig. 6a the overall temperature of the headlight is low.

[0081] Furthermore, Fig. 7b shows the heat flow of the headlight in a state in which the heat is radiated from the headlight through a retaining clip recess to the outside, whereby it can be seen that the Fig. 7b compared to the heat flow of the headlight shown in Fig. 6b, the heat flux is relatively high in a section adjacent to the retaining clip recess. Since the retaining clip recess not only connects the exterior and interior of the headlight, thus forming a passage for heat transfer, but also substantially increases the surface area of the headlight, the heat flux in the section adjacent to the retaining clip recess is high.

[0082] Since the Fig. 7b compared to the heat flow of the headlight shown in Fig. 6b, the heat flow becomes higher in the section adjacent to the retaining clip recess, the heat present within the headlight is slightly radiated outwards from the headlight through the retaining clip recess.

[0083] With reference to Fig. 8a, the heat present inside the headlight is then radiated outwards through the retaining clip when the retaining clip is connected to the headlight. Here it is evident that the Fig. 8a compared to the temperature of the headlight shown in Fig. 7a the overall temperature of the headlight is low.

[0084] It is evident that the Fig. 8b, the heat flux of the headlight is highest in the retaining clip connection. Since the heat present inside the headlight is smoothly transferred to the retaining clip through the retaining clip connection and thus radiated outward from the headlight, the heat radiation performance of the headlight is improved.
