However, the vehicle lamp 10 according to the embodiment of the present invention may be a simple It is possible to provide a vehicle lamp 10 having a depth-sensing image, that is, a gradation surface light source pattern, in addition to the functions of the present invention, thereby satisfying the aesthetic satisfaction demanded by the customers.

3 and 4 are views showing the structure of a lamp 10 for a vehicle according to an embodiment of the present invention.

3 and 4, a vehicle lamp 10 according to an embodiment of the present invention includes an optical assembly 14 composed of a reflecting portion 142, a half mirror 144, and an inner lens 146 . The optical assembly 14 can be received within the housing 16 and the housing 16 can be coupled with the outer lens 12. [ The first light source 142a disposed in the space between the reflective portion 142 and the half mirror 144 and disposed near the edge of the reflective portion 142 and the second light source 142b disposed on the side of the inner lens 146 And may further include a light source 146a.

The first light source 142a and the second light source 146a are accommodated in the housing 16 and can be blinked according to a control signal of the vehicle or a signal of a driver's command. The command of the driver may be configured to be transmitted to the control unit 200 by the first switch 30 and the second switch 40 located in the vehicle. The first switch 30 and the second switch 40 may be configured to be operable by a driver. The first light source 142a and the second light source 146a are controlled to be flickered according to the respective signals will be described in detail below.

In terms of structure, the half mirror 144 is positioned between the inner lens 146 and the reflective portion 142. The half mirror 144 existing at the position can realize a depth sensing image, that is, a gradient surface light source pattern using the principle of reflection of light. The principle that the gradient pattern is implemented by using the reflection principle will be described in detail below.

The half mirror 144 is a kind of mirror that transmits a part of light and reflects a part of light when light is irradiated from a predetermined light source. In the present invention, the half mirror 144 having a reflectance of 80% and a transmittance of 20% is used. However, the present invention is not limited thereto. However, in order to achieve the object of the present invention, it is preferable that the reflectance is larger than the transmittance.

The inner lens 146 is a concept that can be used as an inner lens and includes all the lenses that can be provided in the vehicle lamp 10 that a person skilled in the art can expect. In addition, although the inner lens 146 as one embodiment of the present invention is shown as a planar shape, it is needless to say that a lens having a positive curvature may be used as long as the object of the present invention can be achieved. When the inner lens 146 is composed of an inner lens having a positive curvature, the object of the present invention can be achieved through controlling the thickness of the inner lens 146 or the specification of the second light source 146a. Further, the inner lens 146 may further include a second optic portion (not shown). One of the purposes of the second optic portion is to maximize the amount of light emitted from the inner lens 146, and may be configured to have a concavo-convex shape, but the shape of the second optic portion is not limited thereto. In addition, it may further include a light guide part (not shown). A minute hole may be arranged in the light guide part to express a dot image or the like. However, the shape of the light guide portion is not limited to the above description. The second optic portion or the light guide portion is preferably located on the front surface or the rear surface of the inner lens 146, but is not limited thereto.

The first light source accommodating portion 143 is preferably made of metal, but any material that can be expected by a person skilled in the art is acceptable if it is an electrically conductive material. The reflecting portion 142 located on the first light source accommodating portion 143 has a function of reflecting the light emitted from the first light source 142a toward the half mirror 144 and a function of reflecting the light emitted from the second light source 146a And reflect the light passing through the half mirror 144 toward the half mirror 144 again. The reflective portion 142 is preferably made of an aluminum plate, but is not limited thereto.

The first light source 142a may be configured to be positioned between the reflective portion 142 and the half mirror 144. [ In an exemplary embodiment, the protrusion may extend to the side of the reflective portion 142, which is connected to the half mirror 144, but is not limited thereto. The first light source 142a receives a vehicle control signal and a signal by a driver's command, that is, a switch signal, determines whether the first light source 142a and the second light source 146a are blinking, To the second light source 146a and the control unit 200, which transmits the light to the first light source 142a and the second light source 146a.

The first light source 142a may include a semiconductor point light source and may further include a first optic unit (not shown) surrounding the semiconductor point light source included in the first light source 142a. The first optic portion is for maximizing the amount of light emitted from the first light source 142a. The first optic portion may be formed in a substantially hemispherical shape having a concavo-convex shape, but the shape of the first optic portion is not limited thereto.

The direction in which the first light source 142a receives the lighting signal from the control unit 200 and emits the light may be configured to emit light toward the inside of the space formed between the half mirror 144 and the reflection unit 142 have. The emitted light forms a gradation pattern image through continuous reflection at the reflective portion 142 and the half mirror 144. The gradation pattern lit image refers to an image in which the center of the half mirror 144 is darkest as compared with other portions of the half mirror 144 as the intensity of light gradually decreases toward the center of the half mirror 144. However, this is not an image in which the central part of the half mirror 144 is darkest, but rather an image in which the side of the first light source 142a that emits light is the brightest, and the image which gradually becomes darker toward the other side . That is, if the image is a gradation pattern lit image, it should be understood as a broad concept including any form.

The arrangement of the first light source 142a shown in Fig. 3 is an embodiment of the present invention, and the first light source 142a can be configured to be positioned on both sides of the reflecting portion 142. [ However, it is also possible to dispose the first light source 142a on only one side of the reflector 142, and the number of the first light sources 142a may be one or more, Regardless of revenge. Semiconductor point light sources include all types of point light sources that those skilled in the art would expect, as long as light emitting diodes (LEDs) are desirable but can achieve the object of the present invention.

The second light source 146a may be positioned on the side of the inner lens 146 and fixed by the light source fixing part 148 which fixes the second light source 146a. The second light source 146a may be connected to the controller 200 in the same manner as the first light source 142a and the direction in which the second light source 146a receives the light signal from the controller 200 and emits light And may be configured to emit inwardly of the inner lens 146. However, when the first light source 142a is turned on, the second light source 146a may be turned off, and when the second light source 146a is turned on, the first light source 142a may be turned off. Lt; / RTI > In an embodiment of the present invention, when a predetermined vehicle control signal is a driving signal, only the first light source 142a may be turned on to realize a gradation plane light source pattern lighting image. Conversely, when the predetermined vehicle control signal is a stop signal, only the second light source 146a may be turned on, but the present invention is not limited thereto. That is, the second light source 146a may be configured to be turned on when the predetermined vehicle signal is a driving signal.

When the second light source 146a is turned on, the first light source 142a is turned on to realize the above-described gradation pattern lighting image, and a general simple surface light source image that can be expected by those skilled in the art can be realized. That is, an illuminated image having uniform brightness over the entire area of the inner lens 146 can be realized. This difference is a result of the characteristic of the half mirror 144 that reflects part of the light and transmits part of the light. The process of reflecting the emitted light is shown in FIGS. 6 and 7, and will be described later in conjunction with FIGS. 6 and 7. FIG.

The arrangement of the second light source 146a is an embodiment of the present invention, and the second light source 146a may be arranged on both sides of the inner lens 146. [ However, it is also possible to dispose the second light source 142a only on either side of the inner lens 146, and if the object of the present invention can be achieved, the number of the second light sources 146a may be a single number, Regardless of revenge. The second light source 146a may include a semiconductor point light source. Semiconductor point light sources include all kinds of semiconductor point light sources that a person skilled in the art can expect, as long as light emitting diodes (LEDs) are preferable but can achieve the object of the present invention.

Heat sinks 147 and 149 that can effectively remove the heat of the first light source 142a and the second light source 146a may be installed behind the first light source 142a and the second light source 146a. The heat sink 147 may be divided into a heat sink 147 connected to the first light source 142a and a heat sink 149 connected to the second light source 146a. However, the present invention is not limited thereto.

In addition, cables 145a and 145b may be provided to exchange a predetermined electrical signal between the first light source 142a and the second light source 146a and the control unit 200 of the vehicle. The second light source 146a may be divided into a cable 145a connected to the first light source 142a and a cable 145b connected to the second light source 146a. However, the present invention is not limited thereto.

FIG. 5 shows a lamp 10 for a vehicle to which a light source control module according to an embodiment of the present invention is connected.

Referring to FIG. 5, the first light source 142a and the second light source 146a may be connected to the controller 200 included in the light source control module 20. As described above, the function of the control unit 200 is to receive each signal transmitted from the first switch 202, the second switch 204, and the vehicle control signal transmission unit 206 and to determine which light source is to be turned on Function can be performed. The first switch 202 may be configured to light up the first light source 142a and the second switch 204 may be configured to light up the second light source 146a. The first switch 202 and the second switch 204 can be installed inside the vehicle and can be operated by a driver. However, the first switch 202 and the second switch 204 may be configured to be unselectable in order to achieve the object of the present invention. When the first switch 202 is selected by the driver, a lighting signal for lighting the first light source 142a may be transmitted to the control unit (202a). Likewise, if a second switch is selected by the driver (204a), a light signal may be transmitted to the control unit (204a) in which the second light source 146a is lit.

The vehicle control signal transmitter 206 may transmit a vehicle control signal, for example, a stop signal and a traveling signal. However, the present invention is not limited thereto, and it includes a vehicle control signal that can be expected by a person skilled in the art that may occur during operation. When the vehicle control signal transmission unit 206 receives the vehicle traveling signal and transmits the signal to the control unit 200, the control unit 200 transmits a lighting signal to the first light source 142a based on the signal Lt; / RTI > Similarly, when the vehicle control signal transmitting unit 206 receives the vehicle stop signal and transmits the signal to the control unit 200, the control unit 200 controls the second light source 146a to turn on the light signal based on the signal Lt; / RTI >

The first switch 30 and the second switch 40 that are located inside the vehicle and that respectively control the on-off of the first light source 142a and the second light source 146a may be configured . The first switch 30 and the second switch 40 may be utilized as means for inputting an operator's command. It can be configured so that it can be operated by the driver. Each of the first switch 30 and the second switch 40 may be connected to the first switch signal transmitter 202 and the second switch signal transmitter 204 included in the light source control module 20, respectively. When the driver turns on and off the first switch 30 and the second switch, the first switch signal transmitting unit 202 and the second switch signal transmitting unit 204 transmit predetermined switch signal information related thereto to the controller 200 (202a, 202b). ≪ / RTI > When the driver of the vehicle turns on the first sweeper 30, predetermined signal information related thereto is transmitted to the first switch signal transmitter 202, and the signal is transmitted to the controller 200 (202a). The controller (200) can transmit a turn-on signal to the first light source (142a) based on the received predetermined electric signal. In this case, the first light source 142a is turned on and can emit light. Even when the driver of the vehicle turns on the second switch 40, the above-described operating characteristics can be achieved.

However, only one of the first light source and the second light source may be turned on at a time point. In view of the driver of the vehicle, it is not possible for the driver of the vehicle to simultaneously turn on the first switch 30 and the second switch 40, and the first switch 30 or the second switch 40, The control unit 200 may be configured to determine whether the light source is turned on prior to the predetermined vehicle control signal.

FIG. 6 illustrates a path through which light is emitted from the first light source and reflected when a driving signal or a driver's command is inputted in the vehicle control signal according to an exemplary embodiment of the present invention.

Referring to FIG. 6, when light is emitted from the first light source 142a, the emitted light may be directed to the reflective portion 142 (A '). Assume that the intensity of light at this time is 1. The light incident on the reflective portion 142 may be reflected and directed toward the half mirror 144 (B '), and the intensity of the light may be 1 at this time. In the half mirror 144, the transmittance may be 20% as an embodiment, and 20% is emitted through the inner lens 146 (C ') so that other drivers or pedestrians can recognize the emitted light have. In this case, the emitted light intensity may be 0.2. The light not emitted from the half mirror 144 is again directed to the reflector 142 (D ') and the light is re-reflected E' to 20% of the re-reflected light And is discharged through the inner lens 146 (F '). In this case, the emitted light may be 0.16 less than the intensity of the light emitted through the first inner lens 146. (G ', H', I '), the driver or the pedestrian of the other vehicle can recognize the gradation pattern lighting image which gradually becomes darker toward the center of the vehicle lamp 10 have. This is shown in the lower end schematic 10b of FIG. 8, the brightness of the portion 10b_4 closest to the outermost boundary line of the light emitting portion (not shown) included in the inner lens 146 of the vehicle lamp 10 is set to be the most (10b_3? 10b_2? 10b_1) gradually becomes darker as it progresses to the center of the light emitting portion. However, this is an embodiment, and the shape of the gradient pattern image is not limited by the above description.

However, in FIG. 6, only the first light source 142a located at one side of the first light source accommodating part 143 emits light. However, this is merely to explain the principle of the present invention, But is not limited to. When the entire first light source 142a located on both sides of the first light source accommodating portion 143 is turned on, a light image that gradually becomes darker toward the center of the vehicle lamp 10 can be realized. In addition, when only the first light source 142a located at one side of the first light source accommodating portion 143 is lit, it is possible to realize an illuminated image that gradually becomes darker toward the other side of the vehicle lamp 10. [ However, it is preferable that all of the first light sources 142a located on both sides of the first light source accommodating portion 143 are turned on, although not limited thereto. When only the first light source 142a is lit, other drivers or pedestrians may not recognize the inner lens 146 portion.

FIG. 7 is a diagram illustrating a path in which light is emitted and reflected from a second light source when a stop signal or a driver's command is inputted in the vehicle control signal according to an embodiment of the present invention.

Referring to FIG. 7, when light is emitted from the second light source 146a, the emitted light may be directed toward the half mirror 144 (A). In this case, the intensity of the initially emitted light may be one. In one embodiment, the half mirror 144 has 20% transmission and 80% reflection characteristics, so 20% is transmitted (C) and 80% is reflected (B). The reflected light is emitted outside the inner lens 146 and can be recognized by other drivers or pedestrians. The principle that the light transmitted through the half mirror 144 is reflected and re-reflected is the same as that described with reference to FIG. However, in the case where the second light source 146a is lighted and emits light, an image that does not have a gradation pattern unlike the case where the first light source 142a emits light, that is, A simple surface light source image of the form can be recognized by another driver or a pedestrian. This is because the inner lens 146 itself directly serves as a light guide to emit light forward. Specifically, the intensity of the light B emitted to the outside of the first inner lens 146 and the intensity of the light D and I emitted to the outside of the second third inner lens 146 are almost constant (0.8 , 0.84, 0.832) The other driver or pedestrian is recognized as an image in which there is no gradient pattern, that is, an image in the form of a simple surface light source. The light E and H that are transmitted through the half mirror 144 and reflected and re-reflected by the reflecting portion 142 are transmitted through the half mirror 144 to the (F, J) half mirror 144, It can be combined with the reflected light (B, D, I) without being transmitted to help maintain the intensity of the light in a simple surface light source image realization.

The space between the lower end of the inner lens 146, that is, the reflective portion 142 and the half mirror 144 is not visible due to the presence of the half mirror 144, so that the rear portion of the inner lens 146 is dark, Can realize a bright image. This is shown in the upper part schematic 10a of FIG. 8, in one embodiment, a simple planar light source image may be implemented according to the configuration of FIG. However, in the presence of the half mirror 144, the rear portion of the light emitting portion may be dark and the front portion may be bright.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description, and all changes or modifications derived from the meanings of the claims and their equivalents are included in the scope of the present invention. .
