[0002] This application claims the benefit of Korean Patent Application No. 10-2024-0067962, filed with the Korean Intellectual Property Office on May 24, 2024, the entire contents of which are incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure relates to a lamp for use in vehicles. Background Technology

[0004] Recently, with the increasing demand for entertainment functions beyond the transportation functions required by vehicles, there is a growing need for vehicle lighting fixtures to have additional functions beyond simple illumination. For example, recently, vehicle lighting fixtures have also incorporated functions that enable communication with the outside world.

[0005] In the prior art, vehicle lamps perform the function of communicating with the outside world through visual information (such as an illumination image or light distribution pattern of the vehicle lamp). Meanwhile, in addition to methods using visual information, methods of performing the function of communicating with the outside world also include methods using auditory information such as sound. However, because prior art vehicle lamps employ a watertight structure to prevent moisture accumulation within the lamp, it is difficult to install a speaker configured to output sound within the vehicle lamp.

[0054] Lighting for vehicles

[0055] Figure 1 This is a schematic view illustrating the cross-sectional structure of a vibrating element disposed in a lamp for a vehicle according to the present disclosure, and Figure 2 It shows Figure 1 The view shows the first and second modules of the vibrating section spaced apart from each other. Figure 3 This is a detailed view showing the cross-sectional structure of a vehicle lamp with a vibrating element disposed in accordance with an embodiment of the present disclosure, and Figure 4 It is shown that in the setting Figure 3 An enlarged view of the rib region formed on the second magnet fixing part of the second module in the vibration section. Figure 5 This is a view showing the state in which through holes corresponding to the rib regions formed on the fixing portion of the second magnet are formed in the second magnet, and Figure 6 This is a view showing the state in which the vibrating part is fixed to the lamp housing portion in a lamp for a vehicle according to an embodiment of the present disclosure. Figure 7 yes Figure 6 Enlarged view of the vibrating part in the middle, and Figure 8 It shows Figure 6 The view shown depicts the first and second modules of the vibrating section in a separated state. Figure 9 This is a view showing the state in which the vibrating part is fixed to the outer lens portion of a lamp for a vehicle according to an embodiment of the present disclosure, and Figure 10 It shows Figure 9 A view showing the state of the first and second modules of the vibrating section separated.

[0056] refer to Figures 1 to 10 The vehicle lamp 10 (hereinafter referred to as the "lamp") according to this disclosure may include: a lamp housing portion 100 having an internal space configured to accommodate a light source; and an outer lens portion 200, attached to one side of the lamp housing portion 100 and configured to cover the internal space. More specifically, the outer lens portion 200 may be fixedly attached to the lamp housing portion 100. Light emitted by the light source can be propagated to the outside through the outer lens portion 200, thereby forming a predetermined light distribution pattern and illumination image.

[0057] Furthermore, according to this disclosure, the luminaire 10 can not only form a predetermined light distribution pattern and illumination image like luminaires in the prior art, but also generate sound. More specifically, the luminaire 10 according to this disclosure can output sound by vibrating the luminaire housing portion 100 or the outer lens portion 200.

[0058] To achieve the above objectives, the luminaire 10 according to this disclosure may include a vibrating part 400 fixed to the luminaire housing portion 100 or the outer lens portion 200. The vibrating part 400 may be configured to output sound by vibrating the luminaire housing portion 100 or the outer lens portion 200. Figures 6 to 8 The state in which the vibrating part 400 is fixed to the lamp housing part 100 is shown, and Figure 9 and Figure 10 The vibrating part 400 is shown fixed to the outer lens part 200. The vibrating part 400 can be accommodated in the internal space formed in the lamp housing part 100.

[0059] At the same time, refer to Figures 1 to 5 The vibrating unit 400 may have a structure in which multiple modules are connected. More specifically, the vibrating unit 400 may include a first module 410 and a second module 420 configured to face the first module 410. (See reference...) Figures 3 to 8 The first module 410 can be fixed to one side of the lamp housing portion 100 or the outer lens portion 200, and the second module 420 can be connected to the first module 410. That is, according to this disclosure, as described below, the second module 420 can be relatively fixed to the lamp housing portion 100 or the outer lens portion 200 through the first module 410.

[0060] Return to reference Figures 1 to 5The first module 410 may include a first magnet 412. The first magnet 412 may be a permanent magnet. Furthermore, the second module 420 may include a second magnet 422 configured to face the first magnet 412. The second magnet 422 may also be a permanent magnet. More specifically, the first magnet 412 and the second magnet 422 may be configured to exert a repulsive force between them. The second module 420 may also include: a second magnet fixing portion 424 configured to receive the second magnet 422; and a coil member 426 disposed on one side of the second magnet 422 and received within the second magnet fixing portion 424. For example, as... Figures 1 to 5 As shown, the coil member 426 can be configured to surround the outer periphery of the second magnet 422. According to this disclosure, normally, a constant interval is maintained between the first module 410 and the second module 420 by the repulsive force between the first magnet 412 and the second magnet 422. When current is supplied to the coil member 426, the force applied between the first module 410 and the second module 420 changes over time by electromagnetic force, causing the first module 410 to vibrate. Therefore, when the lamp housing portion 100 or the outer lens portion 200 to which the first module 410 is fixed vibrates, sound can be output from the lamp 10.

[0061] At the same time, such as Figures 1 to 5 As shown, the first module 410 may further include a first magnet fixing portion 414, to which the first magnet 412 is fixed. For example, the first magnet fixing portion 414 may have a generally circular plate shape. In this case, as... Figures 6 to 10 As shown, according to this disclosure, the first magnet fixing portion 414 can be attached to the lamp housing portion 100 or the outer lens portion 200. For example, the first magnet fixing portion 414 can be fixedly connected to the lamp housing portion 100 or the outer lens portion 200 by adhesive or tape. The structure of the second module 420 of the vibrating portion 400 fixed to the lamp housing portion 100 or the outer lens portion 200 will be described in detail below.

[0062] refer to Figures 3 to 5 A through-hole 422a can be formed in the second magnet 422 of the second module 420. A rib region 424a can be disposed on and protrude from the second magnet fixing portion 424 of the second module 420 to be inserted into the through-hole 422a formed in the second magnet 422. The through-hole 422a and the rib region 424a can be configured to position the second magnet 422 at a precise location by aligning the relative positions between the second magnet 422 and the second magnet fixing portion 424. More specifically, the size of the rib region 424a can correspond to the size of the through-hole 422a.

[0063] refer to Figures 6 to 10The first magnet fixing portion 414 of the first module 410 may include a first module sidewall region 414a, which protrudes from the lamp housing portion 100 or the outer lens portion 200 and is configured to define a space for accommodating the first magnet 412. Figures 6 to 8 The first module sidewall region 414a is shown protruding from the lamp housing portion 100. Figure 9 and Figure 10 The first module sidewall region 414a is shown protruding from the outer lens section 200.

[0064] Meanwhile, the second magnet fixing portion 424 may have a configuration corresponding to the first module sidewall region 414a. More specifically, the second magnet fixing portion 424 may include a second module sidewall region 424b extending toward the first magnet fixing portion 414.

[0065] In this configuration, according to the present disclosure, a first helical thread region 414a-1 can be formed in the first module sidewall region 414a, and a second helical thread region 424d can be formed in the second module sidewall region 424b, and the first helical thread region 414a-1 and the second helical thread region 424d can be threadedly connected to each other. That is, according to the present disclosure, the first module 410 and the second module 420 can be fixedly connected by threading to each other. Figures 6 to 8 The diagram shows the state in which the first module 410 and the second module 420 are threadedly connected to each other, such that the vibrating part 400 is fixedly connected to the lamp housing part 100. Figure 9 and Figure 10 The diagram shows the first module 410 and the second module 420 being threadedly connected to each other, such that the vibrating part 400 is fixedly connected to the outer lens part 200. Furthermore, for example, Figures 6 to 10 The diagram shows a state in which a first helical thread region 414a-1 is formed on the outer peripheral surface of the first module sidewall region 414a, and a second helical thread region 424d is formed on the inner peripheral surface of the second module sidewall region 424b.

[0066] Continue to refer to Figures 6 to 10 The first magnet fixing portion 414 may further include a first protruding connecting portion 414b protruding outward from the outer peripheral surface of the first module sidewall region 414a, and the second magnet fixing portion 424 may further include a second protruding connecting portion 424c protruding from the second module sidewall region 424b toward the first magnet fixing portion 414. In this case, the first protruding connecting portion 414b can be fixedly connected to the second protruding connecting portion 424c. For example, as Figures 6 to 10As shown, a recessed section 424c-1 with a recessed shape can be formed in the second protruding connecting region 424c, and at least a portion of the first protruding connecting region 414b can be inserted into the recessed section 424c-1. When the first protruding connecting region 414b and the second protruding connecting region 424c are fixedly connected to each other as described above, the first module 410 and the second module 420 can rotate relative to each other after being threadedly connected, thereby effectively preventing the threaded connection from loosening. For example, Figures 6 to 10 The recessed section 424c-1 is shown to have a hole shape. It can be understood that a portion of the second protruding connecting region 424c has an open shape, and a portion of the first protruding connecting region 414b fits into the open region.

[0067] Figure 11 This is a view used to illustrate another example of a vibrating section disposed in a lamp for a vehicle according to the present disclosure, and shows the first magnet fixing portion of the first module, and Figure 12 This is a view used to illustrate another example of a vibrating section installed in a lamp for a vehicle according to the present disclosure, and shows the second magnet fixing part of the second module.

[0068] refer to Figure 11 and Figure 12 The first helical thread region 414a-1 and the second helical thread region 424d may be discontinuously formed on the inner or outer circumferential surfaces of the first module sidewall region 414a and the second module sidewall region 424b. More specifically, as Figure 11As shown, a plurality of first helical thread regions 414a-1 can be arranged along the peripheral surface (e.g., the outer peripheral surface) of the first module sidewall region 414a and spaced apart from each other, and a plurality of second helical thread regions 424d can be arranged along the peripheral surface (e.g., the inner peripheral surface) of the second module sidewall region 424b and spaced apart from each other. In this case, the plurality of first helical thread regions 414a-1 and the plurality of second helical thread regions 424d can be threadedly connected to each other in a one-to-one manner. When the plurality of first helical thread regions 414a-1 and the plurality of second helical thread regions 424d are arranged along the peripheral surface and spaced apart from each other as described above, a first protruding connecting region 414b can be arranged in the region between two spaced-apart first helical thread regions 414a-1, and a second protruding connecting region 424c can be arranged in the region between two spaced-apart second helical thread regions 424d. More specifically, during the threaded connection operation, the threaded connection can be completed after the first helical thread region 414a-1 has passed over a second helical thread region 424d and before the first helical thread region 414a-1 faces the other second helical thread region 424d. In this case, the degree of interference between the first protruding connection region 414b and the second protruding connection region 424c during the threaded connection process can be minimized.

[0069] Meanwhile, continue to refer to Figure 11 and Figure 12 A smooth curved surface region can be formed in the segment between two adjacent first helical thread regions 414a-1 (i.e., one or more pairs of adjacent first helical thread regions 414a-1) of the first module sidewall region 414a, and a smooth curved surface region can be formed in the space between two adjacent second helical thread regions 424d (i.e., one or more pairs of adjacent second helical thread regions 424d) of the second module sidewall region 424b. In this case, the first helical thread regions 414a-1 and the second helical thread regions 424d can be smoothly threaded together without interference.

[0070] Figure 13 This is a view illustrating the connecting member of the vibrating part of a lamp for a vehicle according to this disclosure, and Figure 14 It is used for explanation Figure 13 A view of the second magnet fixing part of the vibrating section shown.

[0071] At the same time, refer to Figure 13 and Figure 14The second module 420 of the vibrating section 400 may further include a connecting member 428 electrically connected to the coil member 426. The connecting member 428 may be configured to supply current to the coil member 426 or receive electrical signals from the coil member 426. For example, the connecting member 428 may be a conductive PCB or wire.

[0072] In this case, according to the present disclosure, an insertion hole 424-1 can be formed in the second magnet fixing portion 424. More specifically, the connecting member 428 can be configured to pass through the insertion hole 424-1. That is, according to the present disclosure, the connecting member 428 can be configured to penetrate the second magnet fixing portion 424. When the connecting member 428 is configured to penetrate the second magnet fixing portion 424 through the insertion hole 424-1 as described above, interference between the connecting member 428 and the first magnet fixing portion 414 during threaded connection operation can be prevented. Therefore, more specifically, the insertion hole 424-1 can be formed in a region of the second magnet fixing portion 424 as far away from the first module 410 as possible. For example, as Figure 13 and Figure 14 As shown, the insertion hole 424-1 can be formed in the region of the second magnet fixing portion 424 spaced apart from the first module 410 in the direction facing the second magnet 422 from the first magnet 412. That is, based on Figure 13 and Figure 14 With the first module 410 and the second module 420 arranged in the vertical direction, the insertion hole 424-1 can be formed in the upper surface of the second magnet fixing part 424.

[0073] Figure 15 This is another example illustrating a vibrating element installed in a vehicle lamp according to this disclosure, and a view of the second module is shown. Figure 16 It shows Figure 15 A view of the cross-sectional structure of the vibrating part shown.

[0074] refer to Figure 15 and Figure 16The second magnet fixing portion 424 can be divided into multiple regions. More specifically, the second magnet fixing portion 424 may include: a first frame region 424x, configured to receive the second magnet 422 and the coil member 426 and open toward the first module 410; and a second frame region 424y, configured to surround the first frame region 424x and such that the first frame region 424x is fixed to the second frame region 424y. However, the configuration of fixing the first frame region 424x to the second frame region 424y does not mean that the first frame region 424x and the second frame region 424y are configured as separate components. That is, the first frame region 424x and the second frame region 424y can also be integral. However, even if the two components are integral, the two components can be distinguished by the shape features described below.

[0075] refer to Figure 15 and Figure 16 The segment to which the first frame region 424x is fixed to the second frame region 424y may have a shape that protrudes further toward the first module 410 than the peripheral segment to which the first frame region 424x is fixed. The second frame region 424y with the aforementioned protruding shape is configured such that a predetermined interval is provided between the first magnet 412 and the second magnet 422, such that sufficient repulsive force is applied between the first magnet 412 and the second magnet 422.

[0076] Meanwhile, for example, the second module sidewall region 424b can be disposed in the second frame region 424y, and the first frame region 424x can protrude further toward the first module 410 than the second module sidewall region 424b.

[0077] Figure 17 This is a diagram illustrating an example of a vibrating element installed in a vehicle lamp according to the present disclosure, fixed to a radiator. Figure 18 It shows Figure 17 An enlarged view of the second module containing the heat sink and vibrating section. Figure 19 This is a diagram illustrating an example of a vibrating element installed in a vehicle lamp according to the present disclosure, fixed to a radiator.

[0078] refer to Figures 17 to 19The luminaire 10 according to this disclosure may include a heat sink 500 disposed on one side of the luminaire housing portion 100 or the outer lens portion 200. The heat sink 500 may be configured to receive heat generated by a heating element such as a light source of the luminaire 10 and dissipate the heat to the outside. In this case, according to one aspect of the disclosure, a portion of the vibrating portion 400 may be supported by the heat sink 500. More specifically, one side of the second module 420 of the vibrating portion may be supported by the heat sink 500. More specifically, the second module 420 may be fixed to the heat sink 500.

[0079] For example, such as Figure 17 and Figure 18 As shown, one side of the first module 410 disposed in the vibrating section can be fixed to the upper or lower region of the inner surface of the outer lens section 200 extending in a direction intersecting the vertical direction (e.g., the horizontal direction). The second module 420 can be fixed to the end of the upward or downward protruding region of the heat sink 500. Figure 17 and Figure 18 The diagram shows the state in which the first module 410 is fixed to the upper region of the inner surface of the outer lens section 200, and the second module 420 is fixed to the upper end of the upwardly protruding region of the heat sink 500.

[0080] Conversely, as another example, such as Figure 19 As shown, one side of the first module 410 disposed in the vibrating section can be fixed to a region extending in a direction intersecting the horizontal direction (e.g., the vertical direction) on the inner surface of the outer lens section 200. The second module 420 can be fixed to the end of a region protruding in the horizontal direction of the heat sink 500. Figure 19 The diagram shows the state in which the first module 410 is fixed to the forward-formed lateral region of the inner surface of the outer lens portion 200, and the second module 420 is fixed to the front end of the forward-protruding region of the heat sink 500.
