Description

Technical Field

[0001] This invention relates to a control device and method for vehicle lighting fixtures, and more specifically, to a control device and method for vehicle lighting fixtures that enables a lighting fixture to operate in two or more functions. Background Technology

[0002] Typically, vehicles are equipped with a variety of lights that serve the following functions: illumination, which makes objects around the vehicle easily identifiable when driving at night; and signaling, which informs other vehicles or road users of the vehicle's driving status.

[0003] For example, headlights and fog lights are primarily for illumination, while daytime running lights, position lights, turn signals, taillights, and brake lights are primarily for signaling. The setting standards and specifications of each light are stipulated by regulations to ensure that they can fully perform their functions.

[0004] Recently, a lamp has been used for more than two functions. In order for a lamp to be used for more than two functions, various components, including the light source, are required for each function to control the driving power applied to the light source.

[0005] As mentioned above, when a luminaire is equipped with separate components for each function in order to enable it to be used for more than two functions, the increased number of components leads to increased costs and a more complex structure. Therefore, there is a need for a solution that simplifies the structure by reducing the number of components, so that a luminaire can be used for more than two functions.

[0010] In addition, a control device and method for vehicle lamps are provided to remove residual voltage when switching between lamps used for two or more functions, thereby preventing malfunction of the lamps.

[0011] The technical problems to be solved by this invention are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned below through the following description.

[0012] To achieve the aforementioned objective, a control device for a vehicle lighting fixture according to an embodiment of the present invention may include: a drive unit that applies a drive power supply to a lighting module comprising a first light source module operating with a first function and a second light source module operating with a second function, for operating one of the first light source module and the second light source module; and a control unit that receives a drive signal from the lighting module and activates one of the first light source module and the second light source module according to the received drive signal, wherein when the control unit performs a function switch of the lighting module, the control unit may block the application of the drive power supply to the lighting module by the drive unit for a set time, and may switch to the light source module to be activated among the first light source module and the second light source module.

[0013] The first light source module and the second light source module can be operated by driving power supplies of different sizes.

[0016] When the control unit receives the first drive signal, the control unit can apply the drive power used by the drive unit to operate the first light source module to the lamp module. If the control unit receives the second drive signal while receiving the first drive signal, the control unit can deactivate the drive unit to block the application of drive power to the lamp module for the set time.

[0018] The lighting module may further include a first switch section and a second switch section, wherein the control section enables each of the first light source module and the second light source module to be activated or deactivated, wherein the control section can turn on one of the first switch section and the second switch section and turn off the other of the first switch section and the second switch section to enable the lighting module to operate in one of the first function and the second function.

[0023] The control method for vehicle lighting may further include the following steps: before the lighting module operates with the first function, input a drive signal for the operation of the first light source module.

[0024] The steps for the lighting module to operate with the first function may include the following steps: the first light source module is activated and the second light source module is deactivated.

[0025] The drive signal used for the operation of the second light source module can have a higher priority than the drive signal used for the operation of the first light source module.

[0026] The drive signal for operating the second light source module can be input simultaneously with the drive signal for operating the first light source module.

[0027] Other specific aspects of the invention are included in the detailed description and accompanying drawings.

[0028] The control device and method for vehicle lighting according to the present invention, as described above, have one or more of the following technical effects:

[0029] When a luminaire used for two or more functions is operated according to each function, the number of parts can be reduced, the structure can be simplified, and the cost can be reduced because the drive unit that applies the driving power can be shared.

[0030] Furthermore, when switching between functions of a lamp used for two or more functions, the residual voltage can be removed by blocking the application of driving power through the drive unit within a set time, thereby preventing malfunction of the lamp caused by residual voltage.

However, the present invention is not limited to the embodiments disclosed below, but can be implemented in many different forms.

Throughout the specification, the same reference numerals denote the same constituent elements.

[0044] Therefore, in some embodiments, to avoid the invention being interpreted vaguely, well-known process steps, well-known structures and well-known technologies will not be specifically described.

[0045] The terminology used in this specification is for illustrative purposes and is not intended to limit the invention. In this specification, singular forms include plural forms unless otherwise specified in the text.

Thus, the embodiments of the invention are not limited to the specific forms shown, but also include variations in form resulting from manufacturing processes. Furthermore, in the various figures shown in this invention, for ease of explanation, the constituent elements may be shown slightly enlarged or reduced.

[0047] The present invention will now be described with reference to the accompanying drawings, which illustrate a control device and method for vehicle lighting according to an embodiment of the present invention.

[0048] Figure 1 This is a schematic diagram illustrating a control device for a vehicle lamp according to an embodiment of the present invention.

[0049] Reference Figure 1 According to an embodiment of the present invention, the control device 1 for vehicle lighting may include a drive unit 100 and a control unit 200.

[0050] In an embodiment of the present invention, the example described is that the vehicle lighting control device 1 controls the operation of lighting fixtures such as position lights, turn signals, and daytime running lights, which are used to inform drivers or pedestrians of the vehicle's driving status. However, this is only one example to help understand the present invention and is not limited thereto. The vehicle lighting control device 1 of the present invention can control the operation of lighting fixtures installed on a vehicle that are used for various functions.

[0051] The aforementioned lamps can be used for a single function or for two or more functions simultaneously. In the following embodiments of the present invention, the case in which the lamp is used simultaneously for two or more functions with different priorities will be described as an example. The different priorities of the two or more functions can be understood as the function with higher priority being operated when drive signals for operating two or more functions are input simultaneously.

[0052] The drive unit 100 can enable the lighting module 300 to operate in one of a variety of functions by applying drive power to the lighting module 300.

[0053] In an embodiment of the present invention, the case in which the lighting module 300 includes multiple light source modules 310 and 320 that operate with different functions will be described as an example. Hereinafter, in an embodiment of the present invention, the multiple light source modules 310 and 320 will be referred to as the first light source module 310 that operates with a first function and the second light source module 320 that operates with a second function, respectively.

[0054] At this point, the inclusion of two light source modules 310 and 320 in the lighting module 300 is merely an example to help understand the present invention and is not limited thereto. Depending on the function of the lighting module 300, the lighting module 300 may also include three or more light source modules.

[0055] Furthermore, in the embodiments of the present invention, the example is described using the first light source module 310 as a daytime running light and the second light source module 320 as a turn signal light, but it is not limited to this. The functions of the first light source module 310 and the second light source module 320 can be varied.

[0056] The first light source module 310 and the second light source module 320 can be connected in parallel to each other so that one of the first driving power supply used to operate the first light source module 310 and the second driving power supply used to operate the second light source module 320 can be applied to the lamp module 300 by the driving unit 100.

[0057] At this time, the drive unit 100 can convert the power supplied from the vehicle's battery or a separately installed battery into a drive power suitable for each of the first light source module 310 and the second light source module 320.

[0058] As described above, when the drive unit 100 can be shared, since the drive unit 100 is not provided separately for each of the first light source module 310 and the second light source module 320, the number of components is reduced, thereby simplifying the structure and reducing costs.

[0059] In addition, the first light source module 310 may include a plurality of first light sources 311, and the second light source module 320 may include a plurality of second light sources 321. In the embodiments of the present invention, the case in which the first light source module 310 and the second light source module 320 require driving power supplies of different sizes to be described is taken as an example.

[0060] At this time, the situation where the first light source module 310 and the second light source module 320 need different sizes of driving power supplies can include not only the situation where the number of multiple first light sources 311 and the number of multiple second light sources 321 are different from each other, but also the situation where even if the number of multiple first light sources 311 and the number of multiple second light sources 321 are the same, different sizes of driving power supplies may be needed depending on the specifications of the light sources.

[0061] The control unit 200 can perform the following functions: receive a first drive signal for operating the first light source module 310 and a second drive signal for operating the second light source module 320, and control the drive unit 100 to apply the drive power for operating one of the first light source module 310 and the second light source module 320 to the lamp module 300 according to the input drive signal.

[0062] At this time, the drive unit 100 can perform the following function: according to the control of the control unit 200, apply a drive power supply suitable for the size of the light source module to be activated in the first light source module 310 and the second light source module 320 to the lamp module 300.

[0063] The first and second drive signals can be generated by the driver's lever operation, button operation, switch operation, etc., or they can be generated based on vehicle status such as gear position, vehicle speed, and steering angle.

[0064] In an embodiment of the present invention, the case in which the lighting module 300 operates with multiple functions is described as an example. Therefore, the first drive signal and the second drive signal may have different priorities. When the first drive signal and the second drive signal are input at the same time, the control unit 200 controls the drive unit 100 to perform the operation corresponding to the drive signal with higher priority among the first drive signal and the second drive signal.

[0065] In addition, the control unit 200 can activate or deactivate each of the first light source module 310 and the second light source module 320 according to the input drive signal and its priority. The control unit 200 can turn on or off each of the first switch section 312 of the first light source module 310 and the second switch section 322 of the second light source module 320 according to the input drive signal and its priority, thereby enabling each of the first light source module 310 and the second light source module 320 to be activated or deactivated.

[0066] In addition, each of the first light source module 310 and the second light source module 320 may also include a first filter 313 and a second filter 323 for removing noise from the drive power applied by the drive unit 100.

[0067] If the control unit 200 receives another drive signal while receiving one of the first drive signal and the second drive signal, the control unit 200 will deactivate the drive unit 100 to block the drive power supply from being applied to the lighting module 300 by the drive unit 100 for a set time, and switch to the light source module to be activated in the first light source module 310 and the second light source module 320 within the set time. This is to remove the residual voltage within the set time, thereby preventing malfunction of the lighting module 300 due to increased inrush current, etc.

[0068] That is, when switching to the light source module to be activated in the first light source module 310 and the second light source module 320 for the function switching of the lighting module 300, without blocking the driving power applied to the lighting module 300 by the driving unit 100, the residual voltage caused by the difference in magnitude between the first driving power and the second driving power may increase the inrush current, which may cause malfunctions of the lighting module 300 such as flickering. Therefore, during the function switching of the lighting module 300, the driving power will not be applied to the lighting module 300 by the driving unit 100 for a set time in order to remove the residual voltage.

[0069] For example, when a first drive signal is input to the control unit 200, the control unit 200 turns on the first switch unit 312 and turns off the second switch unit 322 to activate the first light source module 310, and applies the first drive power used by the drive unit 100 for the operation of the first light source module 310 to the lamp module 300, so that the lamp module 300 can operate with the first function.

[0070] Furthermore, when a second drive signal with a higher priority than the first drive signal is input during the operation of the lighting module 300 in the first function, the control unit 200 disconnects the first switch unit 312 and turns on the second switch unit 322 to activate the second light source module 320. The second drive power used for the operation of the second light source module 320 is applied to the lighting module 300 through the drive unit 100, so that the lighting module 300 will operate in the second function.

[0071] At this time, when the first light source module 310 includes ten first light sources 311 and the second light source module 320 includes seven second light sources 320, different sizes of driving power supplies are required. In this case, if the driving power applied to the lamp module 300 by the driving unit 100 is not blocked and the switching of the power supply modules to be activated in the first light source module 310 and the second light source module 320 is realized, the inrush current may increase due to the residual voltage, which may cause malfunctions such as flickering of the lamp module 300. Therefore, during the period when the driving power applied by the driving unit 100 is blocked, while the switching of the power supply modules to be activated in the first light source module 310 and the second light source module 320 is performed, the malfunction of the lamp module 300 is prevented by removing the residual voltage.

[0072] In the embodiments of the present invention, the example is given where the first light source module 310 and the second light source module 320 include different numbers of light sources and require different sizes of driving power supplies. However, the invention is not limited to this. Even if the first light source module 310 and the second light source module 320 include the same number of light sources and the size of the driving power supply applied by the driving unit 100 is the same, the invention can be applied similarly in cases where different sizes of driving power supplies are actually required due to manufacturing errors or other reasons.

[0073] Figure 2 This is a schematic diagram illustrating a control device for a vehicle lamp according to another embodiment of the present invention.

[0074] Reference Figure 2 According to another embodiment of the present invention, the control device 1 for vehicle lighting may include a drive unit 100 and a control unit 200 similar to the above embodiment, and the same reference numerals are used for the constituent elements that perform the same function as in the above embodiment, and detailed descriptions of their functions are omitted.

[0075] In another embodiment of the present invention, a discharge section 400, including a bleeder resistance, may be connected between the drive section 100 and the lamp module 300. This is to reduce the time when the drive power applied to the lamp module 300 by the drive section 100 is interrupted, while also removing the residual voltage more quickly.

[0076] At this time, the discharge unit 400 is connected in parallel with the first light source module 310 and the second light source module 320, similar to the drive unit 100 described above, so that the residual voltage generated by one of the first drive power supply and the second drive power supply is quickly removed.

[0077] Figure 3 This is a schematic diagram illustrating the operation timing of a control device for a vehicle lamp according to an embodiment of the present invention. Figure 3 This is an example of a situation where, during the input of the first driving signal, a second driving signal with a higher priority than the first driving signal is input, and the light source module to be activated in the first light source module 310 and the second light source module 320 is switched.

[0078] Reference Figure 3 When the first drive signal is input at t1, the control unit 200 turns on the first switch unit 312 to activate the first light source module 310, turns off the second switch unit 322 to deactivate the second light source module 320, and activates the drive unit 100 so that the first drive power for operating the first light source module 310 is applied to the lamp module 300 through the drive unit 100.

[0079] During the process of applying a first drive signal to the lighting module 300 via the drive unit 100, if a second drive signal with a higher priority than the first drive signal is input at t2, the control unit 200 deactivates the drive unit 100 within a set time (t22-t21) to block the application of drive power to the lighting module 300 via the drive unit 100. Furthermore, within the set time (t22-t21), the first switch unit 312 is disconnected to deactivate the first light source module 310 and the second switch unit 322 is turned on, thereby activating the second light source module 320. After the set time (t22-t21), the drive unit 100 is activated, so that the second drive power for the operation of the second light source module 320 is applied to the lighting module 300, thereby enabling the lighting module 300 to operate in the second function.

[0080] Similarly, when no second drive signal is input at t3, the control unit 200 deactivates the drive unit 100 within a set time (t32-t31), then disconnects the second switch unit 322 and turns on the first switch unit 312, thereby activating the first light source module 310. After the set time (t32-t31), the drive unit 100 is activated, so that the first drive power for the operation of the first light source module 310 is applied to the lamp module 300, thereby enabling the lamp module 300 to operate in the first function.

[0081] As described above, when the function of the lighting module 300 is switched, the drive unit 100 is deactivated for a set time to block the application of driving power to the lighting module 300 through the drive unit 100. Therefore, the residual voltage can be removed during the period when the drive unit 100 is deactivated, thereby preventing the malfunction of the lighting module 300 due to the residual voltage.

[0082] In the above Figure 3In this paper, the following situation is explained: the time (t22-t21) during which the driving power applied to the lighting module 300 by the driving unit 100 is blocked when the second driving signal is input is the same as the time (t32-t31) during which the driving power applied to the lighting module 300 by the driving unit 100 is blocked when the second driving signal is not input. However, this is only for the purpose of helping to understand the present invention. Also, depending on the magnitude of the driving power applied to the lighting module 300 before the driving unit 100 is deactivated, the time during which the driving power applied by the driving unit 100 is blocked may be different when the second driving signal is input and when the second driving signal is not input.

[0083] Figure 4 This is a flowchart illustrating a control method for vehicle lighting according to an embodiment of the present invention.

[0084] Reference Figure 4 The control method for vehicle lighting according to an embodiment of the present invention includes the following steps: first, operating the lighting module 300 in a first function according to a first drive signal (S100); switching the function of the lighting module 300 by inputting a second drive signal with a higher priority than the first drive signal during the input of the first drive signal (S200); and operating the lighting module 300 in a second function according to the second drive signal (S300). The detailed description of each step S100, S200, and S300 is as follows.

[0085] Step S100, which is a step of operating the lighting module 300 in a first function when a first driving signal is input and no second driving signal is input, may include the following steps: inputting a first driving signal (S110); when the first driving signal is input, the control unit 200 turns on the first switch unit 312 and turns off the second switch unit 322 to activate the first light source module 310 (S120); after activating the first light source module 310, the control unit 200 activates the drive unit 100 to apply a first driving power supply for the operation of the first light source module 310 to the lighting module 300 (S130); and the lighting module 300 is operated in a first function by means of the first driving power supply (S140).

[0086] Step S200, which is a step of switching the function of the lighting module 300 by inputting a second driving signal with a higher priority than the first driving signal during the process of operating the lighting module 300 in a first function by means of the first driving signal, may include the following steps: inputting a second driving signal with a higher priority than the first driving signal during the input of the first driving signal (S210); when the second driving signal is input, the control unit 200 deactivates the driving unit 100 to block the application of driving power to the lighting module 300 for a set time (S220); during the period when the driving unit 100 is deactivated, the first switch unit 312 is disconnected and the second switch unit 322 is turned on to activate the second light source module 320 (S230); and the driving unit 100 is deactivated until the set time has elapsed (S240).

[0087] At this time, in step S220 above, since the drive unit 100 is stopped within a set time, the remaining voltage can be removed, thereby preventing the lamp module 300 from malfunctioning, and the remaining voltage can be removed more quickly through the discharge unit 400.

[0088] Step S300, which is a step of reactivating the drive unit 100 that was deactivated in step S200 above and applying a second driving power supply to the lamp module 300 for the operation of the second light source module 320, may include the following steps: reactivating the drive unit 100 after a set time in step S220 above (S310); applying a second driving power supply to the lamp module 300 for the operation of the second light source module 320 via the drive unit 100 (S320); and enabling the lamp module 300 to operate in a second function via the second driving power supply (S330).

[0089] As described above, in the control device and method for vehicle lamps of the present invention, the lamp module 300 is used simultaneously for two or more functions, and when switching the function of the lamp module 300, the remaining voltage is quickly removed by disabling the drive unit 100 within a set time. Thus, when the lamp module 300 is operated with drive power supplies of different sizes, misoperation due to differences in the size of the drive power supplies can be prevented.

[0090] Those skilled in the art will understand that the present invention can be implemented in other specific forms without altering the technical concept or essential features. Therefore, the above embodiments should be understood as exemplary in all respects, not restrictive. The scope of the invention should be defined by the claims rather than by the detailed description above, and all modifications or variations derived from the meaning, scope, and equivalents of the claims should be interpreted as included within the scope of the invention.
