1 is a cross-sectional view illustrating a rear combination lamp for a vehicle according to an embodiment of the present invention. Fig. 2 is a view showing the structure of the rear combination lamp of Fig. 1 as a modular structure.

Referring to FIGS. 1 and 2, a rear combination lamp for a vehicle according to an embodiment of the present invention includes a lens unit that transmits light and emits light, a reflector that reflects incident light to the lens unit, And at least one light source that emits light toward the lens unit, wherein the first light source unit includes at least one light source that emits direct light to the lens unit, And includes a light source portion. At this time, for convenience, a light source that serves to irradiate indirect light is referred to as a first light source 31, and a light source that serves to direct direct light is referred to as a second light source 32. [ The reflection surface on which the light emitted from the first light source 31 directly enters is referred to as a first reflection member 21 and the reflection surface on which reflection light is incident on the first reflection member 21 is referred to as a second reflection member 21, Is referred to as a reflective member 22. A place where the first light source 31 and the second light source 32 are mounted is referred to as a light source mounting place 35.

Here, the lens portion includes a bezel 11, an inner lens 13 disposed inside the bezel 11 to receive indirect light or direct light, and an inner lens 13 disposed on the outer side of the bezel 11, And an outer lens 15 through which light transmitted through the outer lens 15 is transmitted.

The bezel 11 may have a concave shape and the outer lens 15 may be combined with the housing 5 to form an overall shape. The inner lens 13 is located outside the reflection portion and is reflected by the reflection portion and is emitted. The light emitted from the light source 32 passes through the inner lens 13, ) Are emitted together and emitted. The outer lens 15 is located at the outermost position of the rear lamp, and light passing through the inner lens 13 is transmitted and emitted.

At this time, since the inner lens 13 may be caused to diffuse light by indirect light and light by direct light, a method for solving this problem will be described in detail later.

3A is a view for explaining irregular reflection according to the reflection of indirect light, and FIG. 3B is a view for explaining the inner surface of the inner lens to be corroded. Fig. 4A is a view for explaining light incidence of direct light due to the curvature of the inner lens, and Fig. 4B is a view for explaining the outer surface of the inner lens which is corroded.

3A, the light emitted from the first light source 31 is reflected at least once by the first reflecting member 21 and the second reflecting member 22, and is reflected by the inner lens 13 do. That is, the reflector sequentially reflects the light incident from the first light source 31 of the first light source unit at least once by the first and second reflection members 21 and 22, and indirectly reflects the light to the inner lens 13 of the lens unit You can investigate. At this time, an irregularity may occur on the inner surface of the inner lens 13 due to the diffuse reflection of light A1.

Thus, as shown in Fig. 3B, the inner surface of the inner lens 13 is corroded (A2) to prevent an illusion caused by diffuse reflection. In addition to the inner surface of the inner lens 13 being corroded, the reflection surfaces of the first and second reflection members 21 and 22 are vapor-deposited with aluminum or the like. However, by removing vapor deposition of the reflection surface, It is also possible to prevent visibility.

4A, the light emitted from the second light source 32 is directly incident on the inner lens 13. The light incident from the second light source 32 is reflected by the inner lens 13 in a curvature direction The light can be incident on a large portion, and the light beam B1 due to direct light can be generated.

Thus, as shown in FIG. 4B, the outer surface of the inner lens 13 is corroded (B2) to prevent an illusion caused by diffuse reflection.

Therefore, by completely corroding the entire surface of the inner lens 13, it is possible to prevent interference between the indirect light incident on the inner lens 13 and the direct light and the light incidence caused by the direct light. The corrosion of the front surface of the inner lens 13 can be performed by chemical treatment such as calcium chloride or sulfuric acid, and it is natural that a corrosion method obvious to those skilled in the art can be applied.

The reflecting portion includes a first reflecting member 21 and a second reflecting member 22 which can be disposed in front of the first light source portion including the first light source 31 And the second reflecting member 22 may be disposed on the side of the second light source unit including the second light source 32. [ The light emitted from the first light source unit including the first light source 31 is incident on the first reflection member 21 and the second reflection member 22 by arranging the first reflection member 21 and the second reflection member 22, And the light emitted from the second light source unit including the second light source 32 is reflected by the first reflection member 21 and the second reflection member 22, And is directly incident on the inner lens 13. The first reflection member 21 and the second reflection member 22 may be modularized for convenience of installation, and will be described in detail later.

5 is a view showing a reflection module in which a plurality of light sources are mounted in a structure in which the rear combination lamp of FIG. 2 is modularized. 6A is a view for explaining unevenness line unevenness due to deformation of a reflective surface, and FIG. 6B is a view for explaining a rib applied to prevent deformation of a reflective surface.

Referring to Fig. 5, a reflection module 20 including a first reflection member 21 and a second reflection member 22 is shown. In the reflection module 20, a plurality of holes through which a light source is coupled and irradiated with light are formed. The first light source 31 and the second light source 32 emit light in different directions and the light emitted from the first light source 31 toward the first light source 31 And a second reflecting member 22 is formed on the side of the plurality of second light sources 32. The second reflecting member 22 is formed on the side of the plurality of second light sources 32. [ In the reflection module 20, since the reflection surface of the first reflection member 21 may easily deform, the ribs 24 may be formed to prevent the reflection surface.

For example, as shown in FIG. 6A, if the width of the first reflecting member 21 is made thinner, deformation can be easily caused by an external force. Therefore, as shown in FIGS. 5 and 6B, The ribs 24 can be applied. The ribs 24 are applied to the first reflecting member 21 to prevent deformation of the first reflecting member 21 so that the first reflecting member 21 is brought into contact with the inner lens 13 of the lens portion at least at one point Can be maintained.

The first and second light sources include a plurality of light sources, which may be LED light sources having LED (Light Emitting Diode) elements. In this case, a low-voltage and low-power rear combination lamp can be constructed. In addition, the LED has a color temperature of about 5500K, which is close to solar light, which minimizes fatigue in the eyes of the human eye and minimizes the size, thereby increasing the freedom of the design of the lamp and also the economical efficiency due to the semi-permanent lifetime.

For example, as shown in FIG. 7, the shape of the light source mount 35 where the light sources 31 and 32 are mounted in the light source module 30 in which the first light source portion and the second light source portion are formed as a single module, Module 20 so that the design freedom of the rear combination lamp can be further improved. It will be apparent to those skilled in the art that the LED may include any type of LED using an electroluminescent effect such as an OLED (Organic Light-Emitting Diode).

5 and 7, when the reflection module 20 and the light source module 30 are manufactured, the first light source 31 reflects the indirect light reflected from the first and second reflection members 21 and 22, The second light source 32 irradiates the direct light not passing through the first and second reflecting members 21 and 22 with the inner lens 13 so that the light emitted from the first light source 31, The light emitted from the second light source 32 can have a higher luminous intensity in the inner lens 13. [ Thus, the first light source unit including the first light source 31 functions as a tail lamp by irradiating indirect light to the lens unit, particularly, the inner lens 13, and functions as a tail lamp, The second light source unit including the second light source unit emits direct light to the lens unit to perform a stop lamp function.

Therefore, it is possible to realize a tail / stop lamp with a simple structure through the rear combination lamp for a vehicle according to an embodiment of the present invention, and to prevent the indirect light and direct light from being incident on the rear combination lamp, And it is possible to eliminate non-uniformity line unevenness due to the reflection surface deformation.
