Thus, the light e reflected through the reflective layer of the housing to the second semi-transmissive portion 143b. A portion of the silver is transmitted (e1) through the second transflective portion (143b), and a portion is reflected (e2) again toward the reflective layer of the housing. In this case, when the second semi-transmissive part is configured as a half mirror, half of the light is transmitted and half is reflected.

In addition, the light e2 reflected toward the reflective layer of the housing again goes straight toward the second semi-transmissive portion 143b, which is partially transmitted through the second semi-transmissive portion 143b and partially Again reflected f2 toward the reflective layer of the housing.

In addition, the light f2 reflected toward the reflective layer of the housing again goes straight toward the second semi-transmissive portion 143b, which is partially transmitted through the second semi-transmissive portion 143b, and partially Again reflected (g2) towards the reflective layer of the housing.

That is, in the transflective portion, some transmissions and some reflections are continuously repeated, i.e., the light reflected by the transflective portion is partially transmitted and partially reflected, where some transmitted light is represented as an image, and some reflected light is The reflection is reflected back through the reflective layer of the housing to the transflective portion to form the next image, again repeating some transmission and some reflection.

As a result, with this continuous transmission of some transmissions and some reflections, the image formed by the partially transmitted light becomes smaller, thereby forming a sense of depth due to the image.

Meanwhile, in the drawing, some transmission and partial reflection by the second light source assembly 130 and the second transflective part 143b have been described, but the same is true of the first light source assembly 120 and the first transflective part 143a.

Accordingly, the vehicle lamp according to the present invention may divide the inner lens portion into a transmissive portion and a semi-transmissive portion, and may implement a luminance of a predetermined size or more to satisfy the light distribution law of the vehicle lamp by extracting all of the reflected light from the transmissive portion. By repeating some transmissions and some reflections continuously, it is possible to realize a sense of depth image.

5 is a photograph showing an implementation of a vehicle lamp according to the present invention.

Referring to FIG. 5, by repeating some transmissions and some reflections in the transflective portion, an image, such as the shape of the first light source assembly and the second light source assembly, is repeatedly made smaller and smaller, resulting in a sense of depth due to the image. It can be seen that formed.

In addition, it can be seen that by transmitting all of the reflected light in the transmission unit, the luminance of a predetermined size or more that can satisfy the light distribution law of the vehicle lamp.

That is, the inner lens part of the present invention includes a transmissive part and a semi-transmissive part, and the transmissive part can satisfy the light distribution law by transmitting all of the reflected light, and the semi-transmissive part repeatedly transmits and partially reflects the image. By forming a sense of depth due to, it is possible to provide a vehicle lamp that can satisfy the light distribution law and at the same time implement a sense of depth.

6A and 6B are schematic views showing a vehicle equipped with a vehicle lamp according to the present invention.

First, as shown in FIG. 6A, the vehicle 300 may be provided with a vehicle lamp 310 according to the present invention at the rear of the vehicle so as to inform the vehicle located at the rear of the vehicle 300.

In addition, as shown in Figure 6b, the vehicle 300, in addition to the vehicle lamp 310 according to the present invention is installed in the rear of the vehicle so that the vehicle located in the rear to inform the driving state of the vehicle 300, The vehicle lamp 320 according to the present invention may be installed on the side of the vehicle.

In this case, the vehicle lamp according to the present invention is formed long horizontally as the image is formed in the same image as the shape of the first light source assembly and the second light source assembly, when applied to the side of the vehicle, it can further maximize the aesthetic effect. .

However, the vehicle lamp according to the present invention may be variously changed in position, number, size, etc. installed according to the use and need.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
