In addition, in order to increase the reflection efficiency of the reflector 12, a coating layer is formed on the reflecting surface of the reflector 12 by depositing a material having a high reflection coefficient such as aluminum or silver powder.

The conventional vehicle lamp 10 has a reflector 12 and a plurality of lenses 13 and 14 separately configured in addition to the light source 11, and the reflector 12 and the lenses 13 and 14 may reflect light. In order to satisfy various conditions such as diffusion and the like, a separate patterning and coating operation has to be added, and thus there is a problem in that manufacturing cost increases.

In addition, since a considerable separation distance is required between the light source 11 and the plurality of lenses 13 and 14, the space occupied by the vehicle lamp 10 is increased, and the light is subjected to a process such as reflection and diffusion. The loss of is inevitably present. In addition, the lens cut for expressing various images in the vehicle lamp 10 has a problem such that the transparency of the lens is rather reduced.

An object of the present invention is to provide a vehicle lamp that can represent a sense of depth while reducing the space occupied.

2 is a schematic diagram illustrating a vehicle equipped with a vehicle lamp according to an embodiment of the present invention.

As shown, vehicle 100 according to an embodiment of the present invention, the vehicle lamp 200 that can inform the driving state of the vehicle 100 to the vehicle located in the rear may be installed. The vehicle lamp 200 may be changed in position, number, size, and the like, depending on the use and need.

In addition, in the exemplary embodiment of the present invention, the vehicle lamp 200 has been described as an example in which the tail light is installed at the rear of the vehicle. However, the present invention is not limited thereto and includes a direction indicator light, a brake light, It can also be applied to a traffic light, a side marker light, a headlight having an illumination function, a fog light, and the like.

3 is an exploded perspective view showing a vehicle lamp according to an embodiment of the present invention, Figure 4 is a cross-sectional view showing a vehicle lamp according to an embodiment of the present invention.

As shown, the vehicle lamp 200 according to an embodiment of the present invention, the fixing plate 210, a plurality of light sources 211, 212, 213 for generating light on the outside, the outer periphery of the fixing plate 210 The first reflector 220 and the first reflector 220 reflecting the light generated by the plurality of light sources 211, 212, and 213 to the inside of the fixing plate 210 are formed along the first light. A second reflecting unit 230 reflecting through the hole 221 formed by the reflecting unit 220, a transmitting unit 240 transmitting the light reflected by the second reflecting unit 230 according to a predetermined transmittance, and A bezel 250 positioned between the first reflecting unit 220 and the transmitting unit 240 may be included.

In the embodiment of the present invention, the plurality of light sources 211, 212, and 213 are described as an example in which a light emitting diode (Light Emitting Diode) is used, which is faster in response to an incandescent bulb and advantageous in miniaturization. It is merely an example to help understand the present invention, and the present invention is not limited thereto, and an organic light emitting diode may be used.

In this case, the plurality of light sources 211, 212, 213 are fixedly installed along the outer side of the fixing plate 210 by the first reflector 220 to be described later. This is to prevent the light from being reflected from the plurality of light sources 211, 212, and 213 by the first reflecting unit 220 to the inside of the fixing plate 210.

The width of the first reflector 220 may be determined over a range in which light generated by the light sources 211, 212, and 213 reaches. Therefore, the light generated by the plurality of light sources 211, 212, and 213 may be blocked by the first reflecting unit 220, and further progress may be prevented. In other words, the first reflecting unit 220 may be formed by extending in the vertical direction of the fixing plate 210 from the outer circumference of the fixing plate 210 and the end is bent into the fixing plate 210. Therefore, the light generated by the plurality of light sources 211, 212, and 213 is further blocked by the end of the first reflecting portion 220 bent into the fixing plate 210, and is reflected inside the fixing plate 210. Can be.

In addition, the first reflector 220 may have a shape 222 represented by light transmitted through the transmission unit 240. In the exemplary embodiment of the present invention, a case in which the shape 222 is formed at the end of the first reflecting unit 220 through which light generated from the plurality of light sources 211, 212, and 213 arrives will be described.

For example, when a flame shape is formed on a surface on which the light generated by the plurality of light sources 211, 212, and 213 arrives in the first reflecting unit 220, it is represented by light transmitted through the transmitting unit 240. The shape may also be a flame shape that is a shape formed on the first reflection part 220. In addition, the shape 222 formed on the first reflector 220 may be changed according to a user's taste or preference.

On the other hand, in the surface where the light generated by the plurality of light sources 211, 212, 213 reaches in the first reflecting unit 220, the light reflected by the first reflecting unit 220 is moved into the fixing plate 210. It may be inclined to be reflected. In this case, the surface where the light generated by the plurality of light sources 211, 212, and 213 reaches from the first reflecting unit 220 is one surface of the end bent into the fixing plate 210 in the first reflecting unit 220. Can be understood.

When the light reflected by the first reflector 220 reaches the second reflector 230, the second reflector 230 may reflect the reached light through the hole 221 formed by the first reflector 220. The second reflector 230 may be installed inside the fixing plate 210, and may be formed integrally with the fixing plate 210 or may be formed separately.

In addition, the second reflector 230 may have a convex surface where the light reflected by the first reflector 220 reaches, and its curvature may also be changed according to a use and a necessity.

As such, the surface in which the light reaches the second reflector 230 is convex, and the light according to the shape 222 formed in the first reflector 220 is reflected by the second reflector 230. When the light is transmitted through the transmission part 240, an image according to the shape 222 formed in the first reflection part 220 may appear from the outside of the transmission part 240 to the inside of the transmission part 240, and at the same time, When the image according to the shape 222 formed on the first reflecting unit 220 appears, the image size is gradually reduced so that the second reflecting unit 230 has a depth feeling due to the image unlike the convex.

The transmissive part 240 is the light reflected by the second reflector 230 is reflected through the hole 221 formed by the first reflector 220, and the hole 251 formed in the bezel 250 Some of the reflected light may be transmitted according to a predetermined transmittance, and some may be reflected back to the second reflector 230. In the exemplary embodiment of the present invention, the transmissive mirror 240 transmits 1/2 of the light reflected from the second reflector 230 and reflects 1/2 back to the second reflector 230. Half Mirror) will be described as an example.

Therefore, when no light is generated from the plurality of light sources 211, 212, and 213, the transmission unit 240 serves as a mirror to prevent the inside of the vehicle lamp 200 from being seen from the outside. When light is generated from the light sources 211, 212, and 213, an image according to the shape 222 formed in the first reflector 220 may appear.

In addition, since the transmitting part 240 transmits only a part of the light reflected by the second reflecting part 230, the remaining reflected light reaches the second reflecting part 230, and the second reflecting part 230. When the light reaches again, a process of repeatedly reflecting the light reaching the transmission part 240 occurs.

Therefore, as the number of times the light is reflected between the transmissive part 240 and the second reflective part 230 increases, the image appearing in the transmissive part 240 decreases in size toward the inner side of the transmissive part 240. As such, although the second reflecting portion 230 is convexly formed due to the image that is reduced in size toward the inner side of the transmitting part 240, the image may appear with a sense of depth. In addition, the light emitting diode is used as the plurality of light sources 211, 212, and 213 to express an image having a depth in the transmissive part 240, that is, the shape 222 formed in the first reflecting part 220 even when the thickness is thin. have.

5 is a view showing a shape formed in the first reflective portion according to an embodiment of the present invention.

As shown in the drawing, the first reflector 220 according to the embodiment of the present invention may have a predetermined shape 222 formed on a surface on which light generated by the plurality of light sources 211, 212, and 213 reaches. In this case, FIG. 5 illustrates an opposite side of the surface from which the light reaches the first reflecting unit 220. In the embodiment of the present invention, only the surface of the first reflecting unit 220 reaches the shape 222. It may be formed, or may be formed on the opposite side. In addition, the shape 222 may be formed by forming a groove according to the shape 222 on one surface of the end bent in the fixing plate 210 in the first reflection portion 220.

As shown, when no light is generated from the plurality of light sources 211, 212, 213, the transmission part 240 may function as a mirror when viewed from the outside. Therefore, when the light is not generated, it is possible to prevent the internal structure of the vehicle lamp 200 from being visible through the transmission part 240.

As shown in the drawing, when light is generated from the plurality of light sources 211, 212, and 213, the generated light is reflected by the first reflecting unit 220 and the second reflecting unit 230 and transmitted to the transmission unit 240. After reaching, a part of the reached light may be transmitted so that an image 241 according to the shape 222 formed in the first reflector 220 may appear.

At this time, the remaining light except for the transmitted light is transmitted back to the second reflecting unit 230, and the received light is reflected back to the transmitting unit 240. As such, the image 241 according to the shape 222 formed in the first reflecting unit 220 by repetitive reflection between the second reflecting unit 230 and the transmitting unit 240 is in the inward direction of the transmitting unit 240. It may appear as the size decreases.

Thereafter, the reflected light among the light reaching the transmissive part 240 reaches the second reflecting part 230 again, and the reached light is reflected back by the second reflecting part 230 to reach the transmissive part 240. Then, the image 241b located second from the outermost of the image 241 shown in FIG. 8 appears.

Therefore, as the repeated reflection between the second reflector 230 and the transmissive part 240 is performed, the image 241 appearing in the transmissive part 240 may appear smaller and smaller in the direction of the arrow of FIG. 8. As described above, since the size of the image 241 decreases toward the inner side of the transmissive part 240, the second reflective part 230 may have a sense of depth when viewed from the outside despite the convex shape.

In addition, the size of the image 241 appearing in the transmissive part 240 becomes smaller in the inward direction of the transmissive part 240, so that the viewer may have a sense of depth when looking at the transmissive part 240 from the outside.

Meanwhile, although the shape of the transmissive part 240 is illustrated as an example in FIG. 9, this is merely an example to help understanding of the present invention, and the shape of the transmissive part 240 is not limited thereto. It can be made in the shape of a polygon as well as circular.

Hereinafter, the operation of the vehicle lamp according to an embodiment of the present invention will be described in detail.

In operation of the vehicle lamp according to the embodiment of the present invention, when the vehicle lamp 200 is operated first, light is generated from a plurality of light sources 211, 212, and 213 fixed to the fixed plate 210. Light generated by the plurality of light sources 211, 212, and 213 is reflected into the fixing plate 210 by the first reflection part 220 formed along the outer circumference of the fixing plate 210.

In other words, the light generated from the plurality of light sources 211, 212, and 213 in the first reflector 220 reaches one surface of the end bent into the fixing plate 210 in the first reflector 220. At this time, the light reaching surface is formed to be inclined so that the reflected light can be reflected inside the fixing plate (210). In addition, the light reflected from the first reflector 220 may have different reflection angles and be reflected into the fixing plate 210 by the shape 222 formed on the surface where the light reaches the first reflector 220. have.

The light reflected by the first reflector 220 into the fixing plate 210 is reflected by the second reflector 230 positioned inside the fixing plate 210. In this case, the second reflector 230 may have a convex surface on which the light reflected by the first reflector 220 reaches.

The light reflected by the second reflector 230 may reach the transmission part 240 through the hole 221 formed by the first reflector 220 and the hole 251 formed in the bezel 250. . At this time, the light reaching the transmission part 240 reaches the outside of the transmission part 240 due to the convex shape of the second reflection part 230. In addition, the light reaching the transmissive part 240 represents the image 241 according to the shape 222 formed on the surface where the light reaches the first reflecting part 220.

At this time, in the embodiment of the present invention, since the transmissive part 240 illustrates a case of a semi-reflective mirror that transmits a part of the received light and reflects a part of the light, the transmissive part 240 reaches the transmissive part 240. At the same time as the image 241 due to the light appears, some of the light may be reflected back to the second reflector 230.

When the light reflected by the transmissive part 240 reaches the second reflecting part 230, the reached light is reflected by the multi-reflective second reflecting part 230 to be formed by the first reflecting part 220. 221, and the transmission part 240 may be reached through the hole 251 formed in the bezel 25. In this case, the light reaching the transmission part 240 may be weakened due to some light passing through the transmission part 240 compared to the light reaching the transmission part 240. In addition, due to the convex shape of the second reflector 230, the size of the second reflector 230 may be reduced in the inner direction of the transmissive part 240 rather than the position where the first image appears in the transmissive part 240.

As such, due to the convex shape of the second reflecting portion 230 and the repeated reflection of the second reflecting portion 230 and the transmitting portion 240, the image 241 appearing in the transmitting portion 240 is directed toward the transmitting portion 20. The size may get smaller and smaller. Therefore, when looking at the transmission unit 240 from the outside it is possible to feel the depth due to the images.

If no light is generated from the plurality of light sources 211, 212, and 213, the transmissive part 240 may function as a mirror, and thus the vehicle lamp 200 may be viewed when looking at the transmissive part 240 from the outside. It is possible to prevent the inside of the) from being seen.
