1 is a conceptual diagram illustrating formation of a light pattern according to an embodiment of the present invention.

The lamp for a vehicle according to an embodiment of the present invention may include a first optical unit 110 and a second optical unit 120 and may include a first optical unit 110 and a second optical unit 120, Can form the first light pattern P1 and the second light pattern P2, respectively.

In the present invention, the light pattern may include a first light pattern P1 and a second light pattern P2. In particular, the first light pattern P1 may include a side view enhancement light pattern, and the second light pattern P2 may comprise a welcome light pattern.

The side visibility-enhanced light pattern means a light pattern irradiated to a front side area in which a visual field is not ensured by a headlight when traveling at a corner. For example, a light pattern by a static bending lamp (SBL) may be a side view enhancement light pattern, and the first optical section 110 may include a static bending lamp. Therefore, the area where the side view enhancement light pattern, i.e., the first light pattern P1 is formed, based on the position of the vehicle can be fixed but is not limited thereto.

In the present invention, the first light pattern P1 is formed when the vehicle is traveling or is stopped, and may not be formed when the vehicle is parked. That is, the first light pattern P1 can be formed only when the vehicle is started.

The first light pattern P1 may be formed on the front left and front right sides of the vehicle respectively, and may be formed on the rear left and rear right sides. For this purpose, the first optical unit 110 for emitting light toward the front left and the front right may be respectively provided, and the first optical unit 110 for emitting light toward the rear left and rear right may be respectively provided .

The welcome light pattern means a light pattern that provides the same effect as welcoming a user approaching a parked vehicle. When the user's access is recognized or a user command signal such as a door open signal is received from the user, the second optical unit 120 forms a welcoming light pattern.

The welcome light pattern, i.e., the second light pattern P2 according to the embodiment of the present invention may be formed on the ground including a character or a graphic. For example, light may be formed in the shape of a character or a figure, a shadow may be formed in a shape of a character or a figure, and light may be formed in the remaining area. However, the letter or figure included in the second light pattern P2 of the present invention is not implemented only as light or shade, but may be implemented by a combination of light and shade.

In the present invention, the second light pattern P2 is formed when the vehicle is parked, and may not be formed when the vehicle is traveling or standing still. That is, the second light pattern P2 can be formed only when the vehicle is not started.

Like the first light pattern P1, the second light pattern P2 may be formed on the front left side and the front right side of the vehicle, or may be formed on the rear left side and the rear right side. To this end, a second optical unit 120 may be provided to emit light toward the front left and front right sides, respectively, and a second optical unit 120 may be provided to emit light toward the rear left and rear right . According to another embodiment of the present invention, a single second light pattern P2 may be formed by a plurality of optical units. In this case, one second light pattern P2 is formed in front of or behind the vehicle .

The second light pattern P2 of the present invention can provide not only the effect of welcoming the user but also the effect of informing the user of the position of the vehicle. The user can confirm the position of his or her vehicle using the second light pattern P2 formed on the ground. For this purpose, the position of the first light pattern P1 formed on the paper and the position of the second light pattern P2 may be different.

Generally, in a parking lot, vehicles are parked in front or behind the parking lot facing the side, and when the light is emitted farther toward the front or rear of the vehicle, the position of the vehicle can be easily confirmed even at a long distance. Therefore, the position of the second light pattern P2 can be formed farther forward or rearward than the position of the first light pattern P1.

FIG. 2 is a block diagram showing a vehicle lamp according to an embodiment of the present invention. The vehicle lamp 10 includes a control device 200 and a light pattern forming device 100. As shown in FIG.

The control device 200 plays a role of selecting one of the first light pattern P1 and the second light pattern P2 and the optical pattern forming apparatus 100 controls the light pattern selected by the control device 200 .

In order to select a light pattern, the control device 200 can detect the state of the vehicle and whether the user is approaching the vehicle. The state of the vehicle includes the starting state of the vehicle. As described above, the first light pattern P1 is formed only when the vehicle is started, and the second light pattern P2 is formed only when the vehicle is not started. The control device 200 may sense a starting state of the vehicle. To detect a starting state, the control device 200 may include means (not shown) for detecting a starting state or a controller area network (CAN) A signal including information on the state of the vehicle such as a signal or a LIN (Local Interconnect Network) signal can be received from the vehicle and referred to.

The state of the vehicle includes whether or not the driver is on board. Since the formation of the second light pattern P2 is unnecessary after the driver is boarded, the controller 200 can control the optical pattern forming apparatus 100 so that only the first light pattern P1 is formed. Whether or not the driver is boarding can be judged by using the pressure applied to the driver's seat. Accordingly, the control device 200 may include pressure sensing means (not shown) for sensing the pressure of the driver's seat.

The state of the vehicle includes whether or not the vehicle is cornering. When the driver rotates the handle more than a predetermined angle, the controller 200 determines that the vehicle is cornering, and the controller 200 controls the optical pattern forming apparatus 100 so that the first light pattern P1 is formed. In order to determine whether or not the vehicle is cornering, the control device 200 may include means (not shown) for sensing the rotation angle of the steering wheel, or may be provided with a signal including information on the state of the vehicle, such as a CAN signal or a LIN signal, And receive and refer to it.

The state of the vehicle includes whether or not the headlight is turned on. The control device 200 can control the optical pattern unit so that the first light pattern P1 is formed only when the headlight is turned on. In order to determine whether the headlamps are lit, the control device 200 may include a means (not shown) for detecting whether the headlamps are lit or a signal including information on the state of the vehicle, such as a CAN signal or a LIN signal, And can be referred to.

The user's accessibility can be determined through communication with the wireless key possessed by the user. To this end, the control device 200 may include communication means (not shown) for communicating with the wireless key, or may receive a signal including information on the state of the vehicle, such as a CAN signal or a LIN signal, .

The optical pattern forming apparatus 100 forms a first light pattern P1 or a second light pattern P2 according to the state of the vehicle sensed by the controller 200 and the user's accessibility. The light pattern forming apparatus 100 forms a first light pattern P1 or a second light pattern P2 according to a control signal received from the control device 200. [

For example, the optical pattern forming apparatus 100 forms a first light pattern P1 when a control signal (hereinafter, referred to as a first control signal) for forming the first light pattern P1 is received, The second light pattern P2 can be formed when a control signal (hereinafter referred to as a second control signal) for forming the two light patterns P2 is received.

The control device 200 determines that the vehicle is starting and cornering is running and can transmit the first control signal to the optical pattern forming apparatus 100 when the headlight is turned on. Therefore, when the vehicle is judged to be in the cornering running state and the vehicle is not started even when the headlight is turned on, the control device 200 may not transmit the first control signal to the optical pattern forming apparatus 100. [ Likewise, when the vehicle is started and the headlamp is turned off even if it is determined that cornering is being performed, the control device 200 may not transmit the first control signal to the optical pattern forming apparatus 100. [

In addition, the control device 200 can transmit the second control signal to the optical pattern forming apparatus 100 when the vehicle is not started and the user's approach is detected. Accordingly, when the user's approach is detected while the vehicle is being started, the control device 200 may not transmit the second control signal to the optical pattern forming apparatus 100. [

On the other hand, if it is determined that the driver is aboard the vehicle even if the user's access is detected without starting, the control device 200 may not transmit the second control signal to the optical pattern forming apparatus 100. [

Thus, the control device 200 refers to the combination of various peripheral conditions such as the starting state of the vehicle, whether the driver is on board, whether or not the vehicle is cornering, whether the vehicle headlight is turned on, P1 or the second light pattern P2 is formed on the surface of the substrate W.

The optical pattern forming apparatus 100 includes a light source 140, a light path changing unit 130, a first optical unit 110, and a second optical unit 120.

The light source 140 serves to irradiate light. The light from the light source 140 may be irradiated in the form of an intense light or in an indirect light form. To this end, a reflector (not shown) for reflecting light may be provided around the light source 140, and a light guide such as a light guide may be provided.

The optical path changing unit 130 may include a reflector 131 that reflects light from the light source 140 and is irradiated to the first optical unit 110 or the second optical unit 120. [ The position of the reflector 131 is changed so that the light from the light source 140 can be reflected by the first optical unit 110 or reflected by the second optical unit 120. [

When the first control signal is received from the controller 200, the optical path changing unit 130 controls the position of the reflector 131 so that the light from the light source 140 is reflected to the first optical unit 110, When the second control signal is received, the optical path changing unit 130 may control the position of the reflector 131 so that the light from the light source 140 is reflected to the second optical unit 120.

The optical path changing unit 130 may include a selective transmission panel 132 that transmits or reflects the light according to the property of the light to be irradiated to the first optical unit 110 or the second optical unit 120.

The selective transmissive panel 132 may transmit or reflect light according to the properties of the light. For example, the selective transmission panel 132 can reflect light of a specific wavelength or phase, and transmit light of the remaining wavelength or phase as it is. 5 shows that light of a particular wavelength or phase is reflected by the selectively transmissive panel 132 and is directed to the first optical portion 110 and the light transmitted by the selective transmissive panel 132 passes through the second optical portion 120, As shown in FIG.

The reflection plate 133 may be further provided to transmit the light reflected by the selective transmission panel 132 to the first optical unit 110.

When the first control signal is received from the control device 200, the light source 140 may emit light of a specific wavelength or phase and be reflected by the selective transmission panel 132. Thus, the light is reflected again by the reflection plate 133 and transmitted to the first optical unit 110.

When the second control signal is received from the control device 200, the light source 140 may emit light having a different wavelength or phase to be transmitted by the selective transmission panel 132. Thus, the light is transmitted to the second optical section 120.

The first optical portion 110 includes a lens 610 that emits light forward. The light may be incident on the lens 610 at an angle with respect to the incident surface of the lens 610, but may be refracted by the lens 610 and emitted forward in parallel on the exit surface of the lens 610.

The light transmitted by the lens 610 forms the first light pattern P1 to ensure the driver's field of view during cornering.

In the present invention, the lens 610 of the first optical unit 110 may be a transparent or semitransparent light guide. Accordingly, the light can be scattered by the lens 610 and irradiated.
