VEHICLE LAMP HAVING ADJASENT ARRAYS OF LENS AND REFLECTOR LAMPS AND VEHICLE EMPLOYING THEREOF}

The present invention relates to a vehicle lamp, and more particularly to a vehicle lamp having a plurality of unit lamps are arranged adjacent to each other the array of reflector lamp and the lens lamp.

In general, a vehicle includes an lighting device, that is, a vehicle lamp having a lighting function for viewing an object well at night and a signal function for informing a vehicle or other road user of a driving state of the vehicle. For automobile lamps, the level of brightness and the color to be used for each purpose are specified in detail. For example, headlights and fog lights are for lighting purposes, and turn signals, tail lights, brake lights, tail lights and so on are signals. Many lamps having various functions are united in structure, which is commonly referred to as a combination lamp.

Recently, vehicle lamps using photoelectric elements such as light emitting diodes (LEDs) have also been used. The light emitting diodes generate less heat and have a longer lifespan than conventional tungsten or halogen lamps. Headlights 19,000 to 45,000 cd) can also be satisfied, and can emit various colors of light. An example of a vehicle lamp using such a light emitting diode is disclosed in Philips "vehicle headlamps and vehicles", Republic of Korea Patent Publication No. 2001-0072865, published 31 July 2001. This example relates to a headlamp for a vehicle that can arrange and provide photoelectric elements such as light emitting diodes in an array and selectively switch on and off to emit light of a desired color in a desired spatial range.

By the way, in the vehicle lamp provided with two or more conventional LED unit lamps, the structure of each unit lamp was substantially the same. Specifically, a reflector lamp structure in which a conical reflector is installed around each LED arranged at regular intervals from each other. Alternatively, a Fresnel lens was installed on the front of the LEDs arranged at regular intervals to condense the lens lamp structure to diffuse into the fisheye lens. However, in the conventional lamp structure for a vehicle having a plurality of LED unit lamps, there is a disadvantage in that the flexibility of the aesthetic and structural design focusing only on lighting and signal functions.

Car lamps are a very important point in the appearance of the car, in addition to the light-emitting function for lighting or signals. Moreover, at night, the appearance of the car is determined by the shape of the lamp. In today's automobile industry, competition is becoming increasingly important and the exterior design of automobiles is becoming increasingly important. Industrial demand for vehicle lamps having a structure that can be made smaller and more diverse in size or shape while satisfying conventional lighting and signaling functions. Was present.

The present invention aims to improve the structure of a vehicle lamp having a plurality of photovoltaic light sources as described above and to propose a new vehicle lamp having additional advantages.

To this end, it is an object of the present invention to provide a vehicle lamp having a structure that can be smaller in size and more diverse in shape while satisfying an equalizing function such as an illumination function and a signal function.

Another object of the present invention is to provide a vehicle lamp having a structure in which the shape of the concave reflector and the shape of the convex lens are repeated in a predetermined pattern so that it is easy to design images of various patterns.

Another object of the present invention is to provide a vehicle lamp having a structure in which external light reflected from a reflecting mirror is diffusely reflected by an adjacent lens even when it is not lit, so that a sparkling jewelry image can be realized.

In addition, another object of the present invention is to provide a vehicle lamp having a structure that can easily implement a compact combination lamp that can be provided with a variety of colors on a relatively small size scale to satisfy various vehicle lighting functions.

Furthermore, another object of the present invention is to provide a vehicle equipped with the above-described vehicle lamp as a combination lamp having a signal function for informing other vehicles or other pedestrians of the driving state of their vehicle.

In order to achieve the above object, the present invention provides a vehicle lamp provided with a plurality of unit lamps each including one photoelectric element. The vehicle lamp may include: at least one reflector lamp array including a plurality of reflector unit lamps including a reflector configured to reflect and collect light from the photoelectric device; And a lens unit lamp arranged to be adjacent to the reflector lamp array, the lens unit including a lens having an incident surface on which light from the photoelectric element is incident and an exit surface on which light from the incident surface is emitted. At least one lens lamp array.

According to a preferred embodiment, the reflector lamp array and the lens lamp array can each be controlled to be on and off independently. Such control can be controlled automatically by the driver or in accordance with the forward / reverse state of the vehicle. The reflector lamp array and the lens lamp array may emit the same color, but may emit light of different colors, respectively. Here, the lens exit surface is preferably convex to the outside of the lens for the diffusion of light, and when the lens exit surface comprises an angled form, that is, at least two planes that meet at a predetermined angle is similar to the image of the jewelry This has the advantage of making the form easier to implement.

In addition, the reflector lamp array and the lens lamp array may be in the form of a ring in which each unit lamp is arranged in series, wherein the lens lamp array ring may be arranged between the two reflector lamp array ring. In this case, each lamp array ring may include the same number of unit lamps. Thus, for example, a vehicle lamp having a circular array of two reflector lamp arrays and one lens lamp array disposed therebetween can be constructed.

The photoelectric device preferably includes a light emitting diode (LED).

On the other hand, since the exit port side of the reflector of the reflector unit lamp and the lens exit surface of the lens unit lamp are adjacent to each other at the same level, the reflector unit lamp is concave while the lens unit lamp is formed convex. . As such, since the concave reflector and the convex lens are formed to intersect, it is easy to implement a sparkling jewelry image both on and off.

Moreover, this invention provides the vehicle provided with the vehicle lamp which has the above-mentioned characteristic as a signal combination lamp.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Specific embodiments of the present invention are shown in FIGS. 1 to 4, wherein FIG. 1 is a perspective view showing a vehicle lamp according to a preferred embodiment of the present invention, and FIG. 2 is a partially enlarged view showing region A of FIG. 1 in more detail. 3 is a schematic partial cross-sectional view taken along line BB of FIG. 2, and FIG. 4 is a schematic partial cross-sectional view taken along line CC of FIG. 2.

Referring to FIG. 1, a vehicle lamp 10 according to a preferred embodiment of the present invention includes a plurality of unit lamps 12, 14, and 16 each including a photoelectric device such as a light emitting diode. In the present invention, the unit lamps 12, 14, and 16 may be classified into two types. That is, the reflector unit lamps 12 and 16 including a reflector for reflecting and condensing light from the photoelectric element; And a lens unit lamp 14 including a lens having an incident surface on which light from the photoelectric element is incident and an exit surface on which light from the incident surface is emitted. The reflector unit lamp and the lens unit lamp may each be arranged in a ring form, in the form of an array in which a plurality are arranged in series, in the embodiment shown in FIG. 1.

In the embodiment of the circular lamp shown in Fig. 1, a central space 18, which is an empty space, is formed in the center of the area occupied by the lamp. The central portion 18 may be left as an empty space or a separate lamp may be further installed in the central portion 18, if necessary.

Referring to FIG. 2, which shows the area A of FIG. 1 in more detail, a reflector lamp array composed of reflector unit lamps 12 and 16 and a lens lamp array composed of lens unit lamps 14 are disposed adjacent to each other. Preferably, one lens unit lamp 14 is arranged between four unit lamps 12 and 16 so as to be inserted. In other words, the lens lamp array ring is preferably arranged between two reflector lamp array rings. This has the advantage of eliminating unnecessary empty space in the area occupied by the lamp. However, one of ordinary skill in the art will readily understand that such a compact arrangement is not necessarily necessary and that a more loose arrangement is possible due to aesthetic considerations or other structural reasons.

In this case, each lamp array ring preferably includes the same number of unit lamps. The use of the same number of unit lamps is not only easy to produce a constant pattern of a certain size, but also advantageous in manufacturing, assembly and replacement work. However, as mentioned above, it may be composed of different numbers of unit lamps of irregular size, if necessary.

As in the specific embodiment shown, when a vehicle lamp having a circular array of two reflector lamp arrays and one lens lamp array disposed therebetween, the lamps 16 constituting the circular inner reflector lamp array The size of may be smaller than the size of the lamp 12 constituting the outer reflector lamp array. In this case, the lamp 14 constituting the intermediate lens lamp array may have a shape similar to a sparkling jewelry image, such as a diamond or a star.

1 and 2 show a vehicle lamp comprising two arrays of reflector lamps and one array of lens lamps disposed therebetween, but in an alternative embodiment of the present invention, two lens lamp arrays are provided between It can be configured to include one reflector lamp array. Furthermore, in another alternative embodiment of the present invention, the reflector lamp array and the lens lamp array may be included only one line. Since the characteristic idea of the present invention is that the reflector lamp array and the lens lamp array are alternately arranged adjacently, the number of participating array types need not be limited.

3 and 4 show the cross section of each unit lamp 12, 14, 16 in more detail. In figure 3 a cross section of the lens lamp 14 is shown schematically. The lens lamp 14 includes a photoelectric element 144 such as a light emitting diode as a light source and a lens 142 for diffusing it. The lens has an incident surface 142a through which light enters from the photoelectric element 144 and an exit surface 142b that emits light forward. Here, the lens exit surface 142b is preferably convex to the outside of the lens for the diffusion of light. Furthermore, as shown in FIG. 3, the lens exit surface 142b is more preferable when the angle includes a shape that includes at least two planes that meet at a predetermined angle. It has the advantage of being easy to implement. Although not shown, the incident surface 142a may be formed as a concave groove to surround and fix the photoelectric device 144.

Referring to FIG. 4, a cross section of the reflector lamps 12, 16 is schematically shown. The reflector lamps 12 and 16 include photoelectric elements 1244 and 164 and reflectors 122 and 162, respectively. The reflectors 122 and 164 have reflecting surfaces 122a and 162a through which the light from the photoelectric elements 124 and 164 is reflected, and it is easily understood that the reflecting surfaces have a concave shape as a whole. Therefore, the exit port of the reflector from the reflector unit lamps 12 and 16, that is, the end side of the reflecting surfaces 122a and 162a from which light is emitted, and the lens exit surface 142b of the lens unit lamp 14 are adjacent to each other at the same level. In this case, the reflector unit lamps 12 and 16 have a concave shape, while the lens unit lamps 14 have a convex shape. In this case, the concave reflector and the convex lens are formed to intersect. Therefore, both on and off, complex reflection and refraction effects such as light from the light source or light from the outside are reflected, scattered, and diffusely reflected can be generated, and as a result, a shiny gem image can be easily implemented.

According to a preferred embodiment of the present invention, the reflector lamp array and the lens lamp array are preferably controlled to be turned on and off independently of each other. For example, by lighting only the reflector lamp array, it can serve as a red brake light, for example. Meanwhile, when only the lens lamp array is turned on, it may serve as a red tail light. Such control can be for example controlled automatically by the driver or in accordance with the forward / reverse state of the vehicle. The reflector lamp array and the lens lamp array may emit light of the same color as in the example of serving as a brake light and a tail light, but it is also preferable to configure each to emit light of different colors. In this case, various functions may be implemented as one vehicle lamp.

It can be easily understood that the vehicle lamp having the above-described characteristics can be mounted on the vehicle by being configured as a signal combination lamp for indicating a driving state of the vehicle such as a braking light or a tail light.

Many variations can be made by those skilled in the art having the feature of the invention that the lamps of the reflector structure and the array of lamps of the lens structure are alternately arranged. In the illustrated example, circular arrangements are mainly dealt with, but various other forms such as rectangular, oval, and long strips are possible. Therefore, it should be pointed out that the protection scope of the present invention should not be limited to the specific embodiments shown and described, but only by the claims in the claims.

As described above, the present invention improves the structure of a vehicle lamp having a plurality of conventional photoelectric element light sources described above and has additional advantages. The vehicle lamp of the present invention has the effect of being smaller in size and more diversified in shape while satisfying an equalizing function such as an illumination function and a signal function. The vehicle lamp of the present invention has the effect that the shape of the concave reflector and the shape of the convex lens are repeated in a constant pattern to easily design images of various patterns. Furthermore, even when non-lighting, the external light reflected by the reflector is diffusely reflected from the adjacent lens, thereby making it possible to realize a sparkling jewelry image. In addition, it can be provided with a variety of colors in a relatively small size has a remarkable effect, such as easy to implement a compact combination lamp to satisfy the various vehicle lighting functions.
