[0002] This application claims priority and benefit to Korean Patent Application No. 10-2022-0069398, filed on June 8, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present invention relates to prefabricated lighting devices, and more specifically, to prefabricated lighting devices installed on vehicles. Background Technology

[0004] Vehicles are equipped with various types of lights that can emit light forward or illuminate the interior of the vehicle, and recently, there have been cases of setting up mood lights to cater to the user's feelings.

[0005] Mood lights are interior lights installed in vehicles to meet the user's sensitivity through various lighting effects. They can be created by arranging small, light-emitting diodes (LEDs) of various shapes on a wide panel or substrate. Furthermore, to provide a customized atmosphere, mood lights allow users to select and adjust colors and brightness according to their requirements, creating a further improved environment within the vehicle.

[0006] In the case of mass-produced traditional mood lights, long strip lighting is achieved by coupling a single light source to a light guide component that is configured with a long rod-shaped component (such as a light guide).

[0007] However, recently, in addition to simple mood lighting types, there is an increasing variety of development requirements for achieving dynamic effects, and the following difficulties exist: whenever a model is manufactured to validate the product to meet these requirements, a new printed circuit board (PCB) design must be performed, and when the number or specifications of the LEDs used as the light source are changed, the entire design must be executed again. Therefore, there are issues of long processing times and costly losses during the process of validating the initial concept. Summary of the Invention

[0008] The present invention aims to provide a prefabricated lighting device, wherein by allowing modifications corresponding to any structure at the installation location in a vehicle, the efficiency of product unit verification of lighting concepts designed by the initial developer is improved, and the degree of installation freedom is increased.

Regardless of the symbols used in the drawings, the same or corresponding components will be indicated by the same or corresponding reference numerals, and redundant descriptions will be omitted.

[0043] Figure 1 This is a schematic diagram illustrating the state in which a lighting device according to an embodiment of the present invention is installed inside a vehicle, and Figure 2 This is a schematic block diagram illustrating a lighting device according to an embodiment of the present invention.

[0044] The lighting device 1 according to an embodiment of the present invention can be installed inside a vehicle C to achieve interior lighting. In this embodiment, the lighting device 1 can achieve any kind of interior mood lighting to achieve dynamic effects, etc.

[0045] Referring to the accompanying drawings, the lighting device 1 according to an embodiment of the present invention may include a light-emitting diode (LED) block 10, a lighting controller 20, and an input unit 30.

[0046] Multiple LED blocks 10 can be detachably connected to each other via connector 100. Multiple LED blocks 10 can be connected in series and installed inside the vehicle, and the number of LED blocks 10 can vary depending on the installation location and lamp design to be implemented.

[0047] The lighting controller 20 can be detachably connected to the LED block 10 via connector 24 and can control the operation of the LED block 10.

[0048] The input unit 30 can be connected to the lighting controller 20 to input settings for the operation of the LED block 10. In an embodiment, the input unit 30 may include a touch screen display, and vehicle passengers can use the input unit 30 to set the operating mode (on or off, dynamic, etc.), lighting color, lighting brightness, number of LED blocks 10 to be operated, etc. of the LED block 10.

[0049] Such setting information can be sent to the lighting controller 20, and the lighting controller 20 can control the operation of the LED block 10 based on the input information to achieve various mood lighting.

[0050] The LED block 10 and the lighting controller 20 will be described in more detail below.

[0051] LED12 can be mounted on the upper surface of LED block 10. In addition, connector 100 electrically connected to LED12 can be provided on one side surface and the other side surface of each LED block 10.

[0052] Specifically, the LED block 10 may include a base 11 on which a circuit pattern 40 is provided, and the LED 12 may be mounted on the upper surface of the base 11 and connected to the circuit pattern 40. In addition, the connector 100 may include a plug connector 110 disposed on one side surface of the base 11 and a socket connector 120 disposed on the other side surface of the base 11, and may be connected to the LED 12 via the circuit pattern 40.

[0053] With multiple LED blocks 10 connected to each other via plug connector 110 and socket connector 120, the multiple LED blocks 10 can be arranged in series to complete LED block assembly 2. Furthermore, linear lighting can be achieved by adjusting the number of LED blocks 10 connected to each other. Specifically, because the number of LED blocks 10 can be freely changed and installed according to the internal mounting structure of the vehicle C, it has the advantage of increased installation flexibility.

[0054] Each circuit pattern 40 may include a pair of power lines and a pair of communication lines. However, in this embodiment, the structure of the circuit pattern 40 is not limited thereto.

[0055] In this embodiment, the LED12 used as a light source may include an intelligent embedded LED (ISELED). Furthermore, a lens (not shown) that diffuses the light generated by the LED12 may be mounted on the LED12.

[0056] Each base 11 may be a printed circuit board (PCB) or an LMA board, and in this embodiment, the base 11 is shown to be formed in a quadrilateral shape, but the base 11 is not limited to this.

[0057] The lighting controller 20 may include a frame 21 having a circuit pattern (not shown) and a microcontroller unit (MCU) 23 mounted on the frame 21 and connected to the circuit pattern. Furthermore, a connector 24 may be disposed on a side surface of the frame 21 and connected to the MCU 23 via the circuit pattern. The connector 24 may have a shape corresponding to and connected to one of the plug connector 110 and jack connector 120 of the LED block 10.

[0058] In addition, LED22 can also be mounted on the upper surface of frame 21. LED22 can be the same as LED12 of LED block 10 and can be connected to MCU 23 via a circuit pattern.

[0059] In this embodiment, the frame 21 can be a PCB or an LMA board.

[0060] Figure 3 and Figure 4 An LED block 10 and a lighting controller 20 according to one embodiment are illustrated schematically.

[0061] Referring to the accompanying drawings, the LED block 10 can be configured such that the connector 100 and the base 11 are separate components, and the connector 100 is mounted on the base 11. In this case, the base 11 can be configured as a PCB.

[0062] In one embodiment, the plug connector 110 may be connected to one underside of the base 11 to extend forward from one side surface, and the jack connector 120 may be connected to another underside of the base 11 to extend forward from another side surface. That is, the plug connector 110 and the jack connector 120 may be mounted on the base 11 to extend in opposite directions.

[0063] The plug connector 110 and the jack connector 120 can be connected to a circuit pattern (not shown) provided on the base 11 via a connection terminal 123, which passes through the base 11 and is connected to the plug connector 110 and the jack connector 120.

[0064] The plug connector 110 and the socket connector 120 can be configured to form a mechanical connection and an electrical connection, such that the plug connector 110 and the socket connector 120 have corresponding shapes, such that the plug connector 110 is inserted into and secured to the socket connector 120.

[0065] The plug connector 110 may include guide protrusions 111 formed on two side surfaces to project outwards. Furthermore, the corresponding socket connector 120 may include guide grooves 121 formed in two side surfaces to receive the guide protrusions 111. Each guide groove 121 may have a slit-like structure in which the side surfaces of the socket connector 120 are perpendicularly cut, and the slit-like structure may extend and be formed to be longer in the direction in which the socket connector 120 is fastened to the plug connector 110.

[0066] The guide groove 121 may include a hook-shaped protrusion 122 formed at the end to prevent separation of each of the guide protrusions 111, so as to prevent the plug connector 110 from separating due to external impact or the like after the plug connector 110 is secured to the socket connector 120.

[0067] An LED block assembly 2 (see [reference]) can be easily formed by connecting multiple LED blocks 10 such that the socket connector 120 of one LED block 10 is fastened to the plug connector 110 of another LED block 10. Figure 2 This allows for easy implementation of strip lighting. In particular, the number of LEDs used to achieve dynamic lighting can be freely adjusted by simply assembling and connecting the LED blocks 10.

[0068] The lighting controller 20 can also be structured similarly to the LED block 10, with the connector 24 and frame 21 as separate components and the connector 24 mounted on the frame 21. In this case, the frame 21 can be configured as a PCB.

[0069] In this embodiment, a jack connector is shown mounted and connected to the lower surface of frame 21, but the invention is not limited thereto. For example, a plug connector may also be mounted on frame 21.

[0070] Connector 24 can be connected to a circuit pattern (not shown) disposed on frame 21 via connecting terminal 25 passing through frame 21 and connected to connector 24.

[0071] Figure 5 and Figure 6 An LED block 10' and a lighting controller 20' according to another embodiment are illustrated schematically.

[0072] Referring to the accompanying drawings, the LED block 10' can be configured such that the connector 100 extends continuously from the base 11, making the connector 100 and the base 11 integrally formed. In this case, the base 11 can be configured as an LMA board.

[0073] In an embodiment, the plug connector 130 may be formed including a body 131 and a pair of wings 132. The body 131 protrudes outward from one side surface of the base 11, and the pair of wings 132 protrude outward from the lower ends of the two side surfaces of the body 131 to form a stepped structure with the upper surface of the body 131. That is, the plug connector 130 may be formed with a two-stage structure having an upper part A1 and a lower part A2, wherein the upper part A1 has a relatively small width in the width direction perpendicular to the extension direction of the body 131, and the lower part A2 has a relatively large width.

[0074] The jack connector 140 may be formed including a first groove 141 and a second groove 142. The first groove 141 is recessed inward from another side surface of the base 11 and extends downward from the base 11 to accommodate the body 131 of another plug connector 130. The second groove 142 is formed on both lower sides of the first groove 141 to accommodate the wings 132 of the other plug connector 130. That is, the first groove 141 and the second groove 142 of the jack connector 140 may be formed in a shape corresponding to the cross-sectional shape of the two-stage structure of the plug connector 130.

[0075] Meanwhile, multiple connecting protrusions 133 may be provided on the lower surface of the body 131 of the plug connector 130, wherein the circuit pattern 40 is exposed to the outside through the multiple connecting protrusions 133. In addition, multiple connecting grooves 143 may be provided in the bottom surface of the first groove 141 of the socket connector 140, wherein the circuit pattern 40 is exposed through the multiple connecting grooves 143 to correspond to the connecting protrusions 133.

[0076] The connecting protrusion 133 and the connecting groove 143 are formed in the structure to extend into a longer length in the fastening direction of the plug connector 130, and can be formed to engage with each other.

[0077] The circuit pattern 40 is exposed to the outside through the connecting protrusion 133 and the connecting groove 143. Therefore, when the body 131 and the wing 132 of the plug connector 130 are inserted and secured to the first groove 141 and the second groove 142 of the socket connector 140, the connecting protrusion 133 and the connecting groove 143 engage to match each other, and thus the circuit patterns 40 on both sides are connected to each other.

[0078] The lighting controller 20' can be structured similarly to the LED block 10', with the connector 24 and frame 21 integrally formed. In this case, the frame 21 can be configured as an LMA board.

[0079] In this embodiment, connector 24 is shown as a socket connector formed on one side surface of frame 21, but the invention is not limited thereto. For example, plug connectors may also be provided on frame 21.

[0080] Since the specific structure of connector 24, which is configured as a jack connector, is the same as that of jack connector 140 of LED block 10', its description will be omitted.

[0081] Figures 7 to 10 An LED block 10” and a lighting controller 20” according to yet another embodiment are schematically shown.

[0082] Referring to the accompanying drawings, the LED block 10” can be configured such that the connector 100 extends continuously from the base 11, such that the connector 100 and the base 11 are integrally formed. In this case, the base 11 can be configured as an LMA board.

[0083] In an embodiment, the plug connector 150 may be configured to include a horizontal member 151 and a vertical member 152, the horizontal member 151 being parallel to and extending outward from one side surface of the base 11, and the vertical member 152 extending downward from the lower portion of the horizontal member 151 toward the lower surface of the base 11.

[0084] The jack connector 160 may be formed to include a housing member 161, the housing member 161 including a receiving groove 162, the receiving groove 162 being parallel to and extending outward from another side surface of the base 11, opening upward and receiving a vertical member 152 of another plug connector 150.

[0085] The vertical member 152 may have a cylindrical structure and include a plurality of connecting protrusions 153 formed to protrude from its lower surface to expose the circuit pattern 40. The connecting protrusions 153 may be arranged to be spaced at predetermined intervals from the center of the lower surface of the vertical member 152 toward the outer edge.

[0086] Furthermore, the receiving groove 162 provided in the end of the housing member 161 may have a shape corresponding to the shape of the vertical member 152 and include a plurality of connecting grooves 163 formed as recesses in the bottom surface, such that the circuit pattern is exposed to correspond to the connecting protrusion 153. The connecting grooves 163 may be arranged to be spaced apart from each other to form a partially circular track on a concentric circle surrounding the center of the receiving groove 162.

[0087] The circuit pattern 40 can be exposed to the outside through the connecting protrusion 153 and the connecting groove 163. Therefore, when the vertical member 152 is inserted from above the housing member 161 and received in the receiving groove 162, the connecting protrusion 153 and the connecting groove 163 engage to match each other, and thus the circuit patterns 40 on both sides are connected to each other.

[0088] Furthermore, even when the vertical member 152 rotates while being housed in the receiving groove 162, the circuit patterns 40 on both sides remain in contact because the connecting protrusion 153 moves along the track formed by the receiving groove 162.

[0089] Meanwhile, the vertical member 152 may include a protrusion 154 formed on the outer circumferential surface, and the housing member 161 may include a flange 164 protruding from the upper part of the receiving groove 162 toward the inner side of the receiving groove 162. Therefore, when the vertical member 152 is received in the receiving groove 162, the upward movement of the protrusion 154 is blocked by the flange 164, and thus the vertical member 152 is formed to be difficult to separate from the receiving groove 162.

[0090] The lighting controller 20” can also be formed in a similar manner to the LED block 10”, with the connector 24 and frame 21 integrally formed. In this case, the frame 21 can be set as an LMA board.

[0091] In this embodiment, connector 24 is shown disposed on one side surface of frame 21 as a socket connector, but the invention is not limited thereto. For example, plug connectors may also be disposed on frame 21.

[0092] Since the specific structure of connector 24, which is configured as a jack connector, is the same as that of jack connector 160 of LED block 10", its description will be omitted.

[0093] Reference Figure 11 The multiple LED blocks 10” connected to each other by the structure of the aforementioned vertical member 152 and housing member 161 can rotate in various directions to achieve a curved lighting structure. Specifically, because the multiple LED blocks 10” can be freely deformed and installed in a linear or curved manner according to the mounting structure in the vehicle, it has the advantage of increasing the degree of installation freedom.

[0094] Figure 12 An LED block 10”' according to yet another embodiment is shown.

[0095] Referring to the accompanying drawings, the LED block 10”' may include a base 11, which includes a circuit pattern 40, and a plurality of LEDs 12 may be mounted on the upper surface of the base 11 and connected to the circuit pattern 40.

[0096] Multiple LEDs 12 can be arranged to be spaced apart from each other in rows and columns at predetermined intervals. That is, unlike the case where a single LED 12 is provided and each LED block 10 provides point illumination, in this embodiment, the LED block 10"' includes multiple LEDs 12 to provide surface illumination.

[0097] Therefore, by connecting the LED block 10 that realizes point lighting and the LED block 10”' that realizes surface lighting, a design for achieving more dynamic lighting can be implemented.

[0098] The connector 100 may include a plug connector 110 disposed on one side surface of the base 11 and a socket connector 120 disposed on the other side surface of the base 11, and may be connected to a plurality of LEDs 12 via circuit pattern 40.

[0099] As described above, according to an embodiment of the present invention, by prefabricating LED blocks 10 with LEDs 12 installed according to different specifications, selectively connecting and assembling LED blocks 10 that meet the requirements according to the concept to fully form the lighting device 1, and verifying the lighting device 1, the conventional PCB design process performed during the manufacturing model can be omitted, and no new design and manufacturing is required according to changes in the number and specifications of LEDs. Therefore, the loss of time and cost can be prevented during the proof-of-concept process.

[0100] Furthermore, since the lighting device 1 is completely formed by simply connecting and assembling the LED blocks 10, it is possible to easily change the lighting device 1 to correspond to any structure at the location where the lighting device is installed, thus having the advantage of increasing installation freedom.

[0101] According to embodiments of the present invention, a prefabricated lighting device can be provided, wherein the efficiency of product unit verification for lighting concepts designed by the initial developer is improved and the degree of installation freedom is increased due to the variable form of any structure corresponding to the installation location in the vehicle.

[0102] The effects of the present invention are not limited to those described above, and those skilled in the art will clearly understand other effects not mentioned above through the appended claims.

[0103] While the invention has been described above with reference to exemplary embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as defined by the appended claims. Furthermore, it should be understood that differences related to modifications and changes fall within the scope of the invention as defined by the appended claims.
