The control unit 80 controls the first light source unit 30 and the second light source unit 40 to be turned on and off. The control unit 80 has a first mode for turning on the first light source unit 30 and turning off the second light source unit 40, and a second mode for turning on the second light source unit 40 and turning off the first light source unit 30. Mode, a third mode in which the first light source unit 30 and the second light source unit 40 are turned off, and a fourth mode in which the first light source unit 30 and the second light source unit 40 are turned on together are selectively selected. Operate.

For example, if you want to implement the turn signal function, operate it in the first mode, and if you want to implement the daytime running light (DRL) function, operate it in the second mode, and When you want to implement other functions or completely turn off the lights, you can operate the third mode. In addition, the fourth mode with the strongest visibility may be operated in other cases when necessary or in an emergency.

When the control unit 80 is operating in the first mode, that is, the first light source unit 30 is turned on and the second light source unit 40 is turned off, the light irradiated from the first light source unit 30 is shown in FIG. 8. As shown in FIG. 2, the light is finally emitted over a region corresponding to the light guide optics 20.

At this time, the light emitted from the first light source unit 30 is incident into the interior of the light guiding optic unit 20 through one end of the light guiding optic unit 20, as shown in FIGS. 9 and 10, The first optical path proceeding toward the other end of the light-guided optic part 20 along the extension direction of the light-guided optic part 20 by an optical action, and a forward-progression due to the reflective action of the reflective groove part 24 Go through the second optical path. When light proceeds to the second optical path, light is emitted with a uniform luminance throughout the light guide optics 20 due to light mixing and light diffusion of the light transmitting part 23.

In a state in which the control unit 80 is operating in the second mode, that is, in a state in which the second light source unit 40 is turned on and the first light source unit 30 is turned off, the light irradiated from the second light source unit 40 is shown in FIG. As shown in FIG. 1, the light guide area of the bezel 71 and the light guide area of the bezel 71 are finally emitted.

At least a part of the light guiding optics unit 20 according to an embodiment of the present invention is positioned on an optical path through which light emitted from the second light source unit 40 passes through the outer lens unit 10. This means that when viewed from the front, a part or all of the light guiding optics 20 overlaps the light guiding area as shown in FIG. 11.

When a part of the light guiding optical unit 20 overlaps the light guiding area, since the emission is made over the combined area of the light guiding area and the light guiding optical unit 20, a wider emission area can be realized, thereby improving visibility. Can be improved. In addition, when all of the light guiding optics 20 overlap the light guiding area, the first light source unit over the area corresponding to the light guiding optics 20 inside the light guiding area while operating in the fourth mode The luminous intensity or color equal to the sum of the light irradiated from 30 and the second light source unit 40 may be implemented to be different from the outer lens unit 10.

It passes through and proceeds forward, but the light is emitted with uniform luminosity throughout the light guide optics 20 by the light mixing and light diffusion of the light transmitting part 23.

In a state in which the control unit 80 is operating in the fourth mode, that is, in a state in which the first light source unit 30 and the second light source unit 40 are turned on together, irradiation from the first light source unit 30 and the second light source unit 40 As shown in FIG. 11, the light is finally emitted over the light guiding area of the bezel 71 and the area corresponding to the light guiding optical unit 20, but corresponding to the light guiding optics 20 The luminous intensity of the region is higher than that of the second mode, or the color of the region corresponding to the outer lens unit 10 and the region corresponding to the light guide optic unit 20 are different from each other.

For example, the outer lens unit 10 and the light induction optic unit 20 are made of a colorless transparent material, and the first light source unit 30 and the second light source unit 40 emit red and yellow light, respectively. In this case, red light is emitted in the first mode and yellow light is emitted in the second mode, and in the third mode, yellow light is emitted in the area corresponding to the outer lens unit 10, and the light-guided optics 20 In the area corresponding to, an orange light mixed with yellow and red is emitted.

In addition, if the light-guided optics part 20 is formed to extend from the left end of the outer lens part 10 to the right end, even if applied to the left side of the vehicle, the lighting state of the light on the left side of the vehicle as well as on the right side of the vehicle is easy. Can be confirmed. In other words, it is possible to implement improved visibility by a simple structure in which the light guide optics 20 are formed unevenly on the outer lens unit 10.

Accordingly, according to the present invention, compared with the conventional outer lens and vehicle lamp unit, which has a complex optical structure to convert the traveling direction of light irradiated from the rear to the left and right directions, and has a limitation in realizing the aesthetics of the exterior design, With fewer light sources and optical parts, it is not only possible to improve the emission range and visibility more easily, but also to form the overall thickness of the outer lens unit 10 evenly, or to be more freely applied in a desired three-dimensional shape. Diversification and aesthetic improvement can be implemented.

In addition, according to the present invention, when implementing the turn signal function, one of the first light source unit 30 and the second light source unit 40 is turned on, and when the function of the daytime running light is to be implemented, the first light source unit ( 30) and the second light source unit 40, the other side of the light can be operated in a plurality of lighting modes, it is possible to differentiate lighting by function.

More specifically, when the first light source unit 30 is turned on, external light distribution is performed in a shape corresponding to the color of the light irradiated from the first light source unit 30 and the light guide optic unit 20, and the second When the light source unit 40 is turned on, the color of the light irradiated from the second light source unit 40 and the shape corresponding to the light guide area formed by the bezel 71 or the like, or the outer lens unit 10 and the light guide optic unit (20) It is a shape corresponding to the whole, and external light distribution is mainly performed.
