BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a side-

BACKGROUND OF THE INVENTION Field of the Invention [0002] The present invention relates to a vehicular side repeater lamp, and more particularly, to a vehicular side repeater lamp capable of realizing a light irradiated to the outside using a reflecting film.

The rear combination lamps and headlamps for vehicles include a turn signal lamp that flickers at regular intervals during lane change, left turn or right turn during driving.

In addition to the turn signal lamp, a separate side repeater lamp is mounted on the side mirror or the fender panel to clearly indicate the turning direction of the vehicle to the surrounding vehicles or the pedestrian.

The conventional side repeater lamp has a structure in which the light generated in the light source moves along the light guide and then is directly emitted to the outside through the projection lens directly from the ride guide. Since such a structure can realize only one-dimensional lighting effect There is a disadvantage in that the light can not be stereoscopically projected, resulting in a disadvantage that the visual effect is monotonous.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a vehicular side repeater capable of improving the visual effect through the use of a reflective film, The purpose of the lamp is to provide.

According to an aspect of the present invention, there is provided a side repeater lamp for a vehicle, comprising: a housing having a reflective layer on an inner surface thereof and a light source module including a PCB and a light source in an inner space; An inner cover fixed to the housing so as to be positioned in front of the housing and having a surface coated with the inner cover; An inner lens coupled to the inner cover, the inner lens having a light guide integrally formed on one surface thereof and a reflection film coupled to the other surface thereof; And an outer lens fixedly coupled to the housing to be positioned in front of the inner lens.

The reflective layer of the housing is characterized in that when the light source is turned on by the aluminum coating layer, the light emitted through the light guide is reflected backward and a hidden effect is realized when the light source is not illuminated.

The coating layer of the inner cover is characterized in that the aluminum coating layer reflects light scattered outside the inner lens toward the inner lens when the light source is lit, thereby reducing light loss and hiding the light source when the light source is not illuminated.

A light guide is integrally formed along the longitudinal direction of the inner lens on either the lower side or the upper side of the rear surface of the inner lens facing the housing; And a reflective film is coupled to the entire surface of the inner lens facing the outer lens.

The reflective film is an aluminum evaporated reflective film. When the light source is turned on, the reflective film reflects light scattered outside the inner lens to the reflective layer of the housing to reduce light loss and realize a hidden effect by evaporation when the light source is not illuminated .

The reflecting layer of the housing and the reflecting film of the inner lens are configured to be inclined downward so as to reduce diffuse reflection and to realize the depth of the outer lens to be illuminated to the outside.

According to the present invention, the light generated from the light source is irradiated to the outside of the outer lens through the reflection layer of the housing and the reflective film of the inner lens, which are installed at an inclined angle, thereby reducing irregular reflection, It is possible to secure an additional amount of light, and thus the light efficiency of the lamp can be greatly improved.

In addition, since the present invention can realize a depth feeling by the reflection layer and the inner lens, it is also possible to realize a stereoscopic effect of light emitted to the outside of the outer lens.

FIG. 7 is a diagram illustrating a lighting state of a side repeater lamp according to the present invention. FIG.

Hereinafter, a vehicle side repeater lamp according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

The side repeater lamp 100 according to the present invention is mounted on the outside mirror 1 of the vehicle as shown in Figs. 1 to 7, thereby clearly indicating the turning direction of the vehicle to the surrounding vehicles or the pedestrian.

The side repeater lamp 100 includes a housing 10 fixed to the outside mirror 1, a light source module 20, an inner cover 30, an inner lens 40, and an outer lens 50.

The housing 10 is preferably provided with a reflective layer 11 on the inner surface facing forward and is preferably a black smog color so as to realize a hidden effect when the light source is not illuminated. It can be implemented variously.

The light source module 20 includes a plurality of LED light sources 21, a PCB 22 for controlling power supply to the light source 21, a wire 23 electrically connecting the light source 21 and the PCB 22 And is installed in the inner space of the housing 10.

The inner cover 30 is fixedly coupled to the housing 10 so as to be positioned in front of the housing 10 and a coating layer 31 is provided on the surface thereof.

The inner lens 40 is coupled to the inner cover 30, a light guide 41 is integrally formed on one surface, and a reflective film 42 is coupled to the other surface.

The outer lens 50 is fixedly coupled to the housing 10 so as to be positioned in front of the inner lens 40.

Only the outer lens 50 is installed so as to be exposed to the outside of the outside mirror 1 so that the light generated by the light source 21 is finally irradiated to the outside through the outer lens 50.

The reflective layer 11 of the housing 10 is an aluminum coating layer. When the light source 21 is turned on, the light emitted from the light guide 41 is reflected backward. When the light source 21 is turned off, , A hidden effect is implemented to realize a high quality lamp.

The coating layer 31 of the inner cover 30 is an aluminum coating layer that reflects light scattered outside the inner lens 40 toward the inner lens 40 when the light source 21 is lit, And when the light source 21 is not illuminated, the reflection effect of the reflection layer 11 is realized to realize a high quality of the lamp.

The reflective film 42 is a reflective film formed by deposition of aluminum and reflects light scattered outside the inner lens 40 to the reflective layer 11 of the housing 10 when the light source 21 is lit. The light loss is reduced. When the light source 21 is not illuminated, a hidden effect due to vapor deposition is realized, thereby realizing a high-quality feeling of the lamp together with the reflective layer 11 and the coating layer 31.

The light guide 41 is integrally formed on the rear surface of the inner lens 40 facing the housing 10 and is provided along the longitudinal direction (left and right direction) of the inner lens 40 on either the lower side or the upper side of the rear surface. do.

A light source 21 is provided at one end of the light guide 41 so that the light generated by the light source 21 moves along the light guide 41 and then is emitted outside the light guide 41.

The embodiment according to the present invention has a structure in which the light guide 41 is integrally formed on the rear surface of the inner lens 40 without using a separate assembly member, thereby reducing the number of components and reducing the cost.

Further, when the light guide 41 is coupled to the inner lens 40 by a separate assembling member, there is a fear that an image of reflection by the assembling member is generated at the time of lighting the light source 21. In this case, In order to prevent this, the light guide 41 may be fixed to the inner lens 40 by using a separate assembling member so as to prevent the light efficiency of the outer lens 50 from being insufficient. But the structure is formed integrally.

Further, the reflection film 42 according to the present invention is bonded to the front surface of the inner lens 40 facing the outer lens 50.

Since the outer lens 50 is shrunk due to the nature of the injection process, it is difficult to produce the outer lens 50 at a thickness of at least 3 mm. The present invention is not limited to the case where the reflective film 42 is attached to the inner lens 40 manufactured separately from the outer lens 50 So that the distance from the outer lens 50 is maximized, so that the light can be solidified by the depth sense.

In the embodiment of the present invention, the reflection layer 11 of the housing 10 and the reflection film 42 of the inner lens 40 are installed in a structure inclined downward at a predetermined angle with respect to a vertical line, It is possible to reduce the thickness of the outer lens 50 and to realize the depth of light.

That is, when light is generated in the light source 21, the light travels along the light guide 41 of the inner lens 40 and then is emitted through the light guide 41. The light emitted from the light guide 41 A part of the light is irradiated to the outside through the inner lens 40 and the outer lens 50 (solid line arrow M1) and the remaining part of the light is reflected by the reflective film 42 of the inner lens 40, (Dotted arrow M2)

At this time, the reflective layer 11 of the housing 10 and the reflective film 42 of the inner lens 40 are installed in a downward inclined structure with respect to a vertical line, thereby improving reflection efficiency and reducing irregular reflection.

Particularly, by controlling the inclination angles of the reflective layer 11 and the reflective film 42, it is possible to minimize irregular reflection on the reflective film 42.

The light reflected by the reflecting layer 11 of the housing 10 by the reflecting film 42 is again reflected by the inner lens 40 and is irradiated to the outside through the outer lens 50, The light loss due to light can be greatly reduced, and further, the light quantity can be secured, so that the light efficiency of the lamp can be greatly improved.

The light emitted from the light guide 41 is reflected repeatedly over the entire height of the reflective film 42 by the reflective film 11 of the housing 10 and the reflective film 42 of the inner lens 40, The light emitted from the light guide 41 is emitted from the light guide 41 at a position where the light guide 41 is located at the lowest position and the light guide 41 is located far away from the light guide 41. [ (Upper side), the intensity of the light is gradually weakened. As a result, the depth feeling can be realized, thereby realizing the light irradiated to the outside of the outer lens 50 (see FIG. 7).

As described above, according to the embodiment of the present invention, the light generated from the light source 21 is incident on the outer lens 50 through the reflection layer 11 of the housing 10 and the reflection film 42 of the inner lens 40, The light loss due to scattered light can be largely reduced, and additional light quantity can be secured, which is advantageous in that the light efficiency of the lamp can be greatly improved.

Also, the embodiment according to the present invention has an advantage of realizing the stereoscopic effect of the light irradiated to the outside of the outer lens 50 as the depth feeling can be realized by the reflection layer 11 and the inner lens 40. [

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims It will be apparent to those of ordinary skill in the art.
