Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to and the benefit of Korean Patent Application No. 10-2021-0002816 filed in the Korean Intellectual Property Office on Jan. 8, 2021, the entire contents of which are incorporated herein by reference. 
     TECHNICAL FIELD 
     The present disclosure relates to a lamp for a vehicle including a plurality of light sources and a vehicle including the same. 
     BACKGROUND ART 
     An adaptive driving beam (ADB) lamp mounted on a vehicle has a shape evolved from a high-beam lamp in the related art. When an oncoming vehicle is present in front of a host vehicle, the ADB lamp forms a dark zone on a part of a beam pattern by turning off a light source for emitting light to a region in which the oncoming vehicle is present, thereby preventing light blindness of a driver in the oncoming vehicle. 
     The ADB lamp is mounted with a plurality of LEDs and may form the partial dark zone by individually controlling operations of turning off the plurality of LEDs. 
     Meanwhile, the number of LEDs mounted in the ADB lamp needs to increase to precisely control the dark zone formed on the beam pattern formed by the ADB lamp. However, the increase in number of LEDs also complicates a structure of the lamp for a vehicle in which the LEDs are mounted. Therefore, it is necessary to optimize the arrangement of LEDs and circuits to develop the ADB lamp having a large number of LEDs.

     DETAILED DESCRIPTION 
     Hereinafter, a lamp for a vehicle and a vehicle according to the present disclosure will be described with reference to the drawings. 
     Lamp for Vehicle 
       FIG. 1  is a view illustrating a structure of a lamp for a vehicle according to a first embodiment of the present disclosure. 
     As illustrated in  FIG. 1 , a lamp  10  for a vehicle according to the present disclosure may include a first LED group  110  including a plurality of LEDs disposed to be spaced apart from one another in a first direction D 1 .  FIG. 1  illustrates an example in which the first LED group includes six LEDs disposed to be spaced apart from one another at an equal interval in the first direction D 1 . However, the number of LEDs disposed in the first LED group  110  is not limited to the number of LEDs illustrated in the drawing. In the drawing, reference numeral  112  is assigned to the LED disposed in the first LED group  110 . 
     In addition, the lamp  10  for a vehicle may include a second LED group  120  spaced apart from the first LED group  110  in a second direction D 2  that perpendicularly intersects the first direction D 1 , and the second LED group  120  may include a plurality of LEDs disposed to be spaced apart from one another in the first direction D 1 .  FIG. 1  illustrates an example in which the second LED group  120  includes six LEDs disposed to be spaced apart from one another at an equal interval in the first direction D 1 . However, the number of LEDs disposed in the second LED group  120  is not limited to the number of LEDs illustrated in the drawing. In the drawing, reference numeral  122  is assigned to the LED disposed in the second LED group  120 . 
     In addition, the lamp  10  for a vehicle may further include: a matrix IC (integrated circuit) unit  200  spaced apart from the first LED group  110  in the second direction D 2  and including a plurality of FET (field effect transistor) elements (not illustrated); a first circuit  310  configured to connect, in series, the plurality of LEDs  112  disposed in the first LED group  110  and the plurality of LEDs  114  disposed in the second LED group  120 ; and second circuits  320  branching off from the first circuit  310  and connected to the FET elements provided in the matrix IC unit  200 . 
     In this case, according to the present disclosure, the first circuit  310  may include: a first region  312  configured to connect two LEDs  112  and  122  respectively disposed in the first and second LED groups  110  and  120  and spaced apart from each other in the second direction D 2 ; and a second region  314  configured to connect two LEDs  112  and  122  respectively disposed in the first and second LED groups  110  and  120  and spaced apart from each other in the direction that intersects the first direction D 1  and the second direction D 2 . Therefore, according to the present disclosure, the LED  112  disposed in the first LED group  110  and the LED  122  disposed in the second LED group  120  may be connected in series by the first and second regions  312  and  314  that constitute the first circuit  310 . 
     Meanwhile, according to the present disclosure, the second circuits  320  may branch off from the first and second regions  312  and  314  of the first circuit  310  and connect the first and second regions  312  and  314  to the plurality of FET elements in a one-to-one manner. Therefore, according to the first embodiment of the present disclosure, the number of second circuits  320  may be equal to a total sum of the number of first and second regions  312  and  314 . For example, as illustrated in  FIG. 1 , the number of second circuits  320  may be eleven when the number of first regions  312  of the first circuit  310  is six and the number of second regions  314  of the first circuit  310  is five. 
     Meanwhile, according to the present disclosure, the first circuit  310  may include a section in which the first and second regions  312  and  314  are alternately disposed. More particularly, the first circuit  310  may have a structure in which the first and second regions  312  and  314  are alternately disposed. This structure of the first circuit  310  may serve to connect, in series and in a zigzag manner, the plurality of LEDs  112  disposed in the first LED group  110  and the plurality of LEDs  122  disposed in the second LED group  120 . 
     Meanwhile, according to the first embodiment of the present disclosure, the plurality of LEDs constituting the lamp  10  for a vehicle may be arranged symmetrically in the first direction D 1  and the second direction D 2 . Therefore, the lamp  10  for a vehicle according to the first embodiment of the present disclosure may have a shape symmetric in an upward/downward direction and a leftward/rightward direction. 
     According to the present disclosure, the plurality of LEDs  112  disposed in the first LED group  110  and the plurality of LEDs  122  disposed in the second LED group  120  may be connected in series by the first circuit  310 , and the second circuits  320  branching off from the first circuit  310  may be additionally provided, which makes it possible to individually control the operations of turning on or off the LEDs provided in the lamp  10  for a vehicle. 
     That is, to turn on a particular LED among the plurality of LEDs provided in the lamp  10  for a vehicle, electric current is supplied to the particular LED through the first or second region  312  or  314  connected to the particular LED and disposed at an upstream side from the particular LED based on a direction in which the electric current flows. 
     However, to turn off the particular LED, electric current is controlled and supplied to the FET element through the second circuit  320  branching off from the first or second region  312  or  314  connected to the particular LED and disposed at the upstream side from the particular LED. The electric current supplied to the FET element is supplied to the first or second region  312  or  314  disposed at a downstream side from the particular LED, through another second circuit  320  disposed at a downstream side from the FET element. That is, according to the present disclosure, the second circuit  320  may serve to allow the electric current flowing along the first circuit  310  to bypass the LED without passing through the LED. 
       FIG. 2  is a view illustrating a structure of a lamp for a vehicle according to a second embodiment of the present disclosure.

In more detail, the additional LED group  150  may be disposed at one side of the first LED group  110  in the first direction D 1 . In the drawing, reference numeral  152  is assigned to the LED disposed in the additional LED group  150 . In addition,  FIG. 2  illustrates an example in which the additional LED group  150  is disposed at a right side of the first LED group  110  in the first direction D 1 . 
     In more detail, according to the second embodiment of the present disclosure, the additional LED group  150  may include a plurality of LEDs  152  disposed to be spaced apart from one another in the first direction D 1 , and the additional circuit  350  may connect, in series, the plurality of LEDs  152  disposed in the additional LED group  150 . However, alternatively, the additional LED group  150  may include only a single LED. 
     In addition, according to the second embodiment of the present disclosure, the second circuits  320  may branch off from the first and second regions  312  and  314  of the first circuit  310 , and the second circuit  320  may also branch off from the additional circuit  350 .
