Hereinafter, with reference to the accompanying drawings will be described an embodiment of a lighting device according to the present invention. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a perspective view of a lighting device according to an embodiment of the present invention, Figure 2 is an exploded perspective view of a lighting device of the device according to an embodiment of the present invention, Figure 3 is a view of the device according to an embodiment of the present invention Sectional view of the lighting device.

1 to 3, a lighting device according to an embodiment of the present invention includes a housing 100, a light guide member 200, and a panel 300.

The housing 100 forms a space 110 open upward. In addition, the housing 100 forms the pair of recessed recesses 120 downward from the space 110 so as to be independent of each other. The recessed grooves 120 serve to independently mount the light sources 10, respectively. Thus, the space 110 is connected to two or more recessed grooves 120. For convenience, the recessed groove portion 120 is shown to be formed two. In particular, the light source 10 may be variously applied, such as an LED, and emits light when power is applied from the outside. The structure in which the light source 10 is connected to an external power source is general.

Of course, the shape of the housing 100 can be variously applied.

On the other hand, the light guide member 200 is detachably mounted to the housing 100. The light guide member 200 is made of a transparent material as a whole. In particular, since the light guide member 200 is a transparent material, it is scattered while the light is transmitted. Thus, the light sources 10 mounted on the recessed recesses 120 form a portion where the light overlaps upon light emission.

In more detail, the light guide member 200 includes a light incident member 210, a function branch member 220, and a state branch member 230.

The light incidence member 210 is a portion accommodated in each recessed groove 120 of the light guide member 200, and serves to directly inject the light of the corresponding light source 10.

In addition, the functional branch members 220 are integrally formed by being laminated while extending from the upper edges adjacent to each other of the neighboring light receiving members 210, and the state branching members 230 are opposite to each other of the neighboring light receiving members 210. The upper edge is independently formed so as not to be connected to the functional branch member 220, respectively.

At this time, the functional branch member 220 forms a functional irradiation surface portion 240 on the upper side, each of the independent state branch members 230 forms a state irradiation surface portion 250 on the upper side.

On the other hand, the housing 100 further includes a panel 300 on the upper side. The panel 300 forms a function recognition member 310 to correspond to the function irradiation surface portion 240 of the light guide member 200 and simultaneously corresponds to the state irradiation surface portion 250 of the light guide member 200. To form a use state discriminating member 320.

For convenience, two light sources 10 are illustrated, and the light guide member 200 has one functional irradiation surface portion 240 and two state irradiation surface portions 250. At this time, the light guide member 200 forms a functional irradiation surface portion 240 in a range in which the light of the light source 10 is overlapped when emitting light at the same time. Therefore, even if either light source 10 emits light, the functional irradiation surface portion 240 transmits light. Of course, when one light source 10 emits light, the state irradiation surface 250 corresponding to the light source 10 transmits light.

In particular, the use state discriminating member 320 is formed in the panel 300 so as to correspond to each of the light sources 10 to induce the light from the corresponding light source 10 to the outside. Therefore, the use state discriminating member 320 is formed equal to the number of light sources 10. At this time, the use state discriminating member 320 is preferably made of a hole shape through the panel 300. Thus, the use state discriminating member 320 transmits the light of the corresponding light source 10 so that the user can visually check whether the device is operating or operating state through which light source 10 emits light. Of course, the use state discriminating member 320 can be applied in various forms.

In addition, the function recognition member 310 is formed on the panel 300, and transmits the light of at least one light source 10 of the different light sources 10 so that the user can recognize the use function of the device. do. Of course, the function recognition member 310 may be irradiated with overlapping light of two or more light sources 10. Here, the function recognition member 310 is shown in a hole shape, it can be variously applied.

At this time, each of the state irradiation surface portion 250 corresponds to each of the use state discriminating member 320 independently, the function irradiation surface portion 240 is formed to correspond to the function recognition member 310.

In addition, the pair of functional branch members 220 are laminated to form the functional irradiation surface portion 240 on the upper side, the independent state branch member 230 forms the state irradiation surface portion 250 on each upper side.

On the other hand, the light receiving member 210 forms a receiving groove 212 to accommodate the light source 10 inside the housing 100. This is to maintain the illuminance emitted through the function recognition member 310 and the use state discriminating member 320 to transmit the most light of the light source 10 to a predetermined value or more.

 The state irradiation surface 250 and the function irradiation surface 240 form an uneven portion 260 which is etched. This is to improve the visibility of the function recognition member 310 and the use state discriminating member 320 by increasing the degree of scattering of the light transmitted.

In addition, the recessed groove portion 120 forms an inclined wall surface 130 inclined symmetrically with respect to the center. This means that even when the light of each light source 10 hits the inclined wall surface 130, it is reflected and irradiated to the corresponding use state discriminating member 320 or the function recognition member 310, and also does not correspond to the use state discriminating member. This is to prevent the reflection at 320.

Hereinafter, the operating state of the lighting device of the present invention configured as described above will be described in detail.

For convenience, the function recognition member 310 is displayed as 'SHIFT' indicating the position shifting function of the lever (not shown) for the gear setting of the vehicle, the use state discriminating member 320 is the function recognition member 310 It is represented by 'UP' and 'DOWN' indicating the correct state.

Of course, the function recognition member 310 and the use state discriminating member 320 can be variously applied.

Here, since the use state discriminating member 320 is provided with two, the panel 300 is preferably arranged in order of the use state discriminating member 320, the function recognition member 310, and the use state distinguishing member 320.

That is, the function recognition member 310 is engraved between the at least two use state discriminating member 320 in the panel 300. Of course, the function recognition member 310 may increase the required number according to the number of use state discriminating member 320. At this time, the function recognition member 310 is less than the number of the use state discriminating member 320 so as to be able to overlap the light of the two or more light sources 10. Therefore, even if only one light source 10 emits light, the light of the light source 10 is always emitted to the outside of the panel 300 through the function recognition member 310, so that the user has a function such as a role of the device. You can check in the dark.

In more detail, when the light source 10 mounted on the housing 100 emits light so as to correspond to the use state discriminating member 320 denoted as 'UP', the light is recessed in the corresponding recess 120 and the light receiving member 210. Through the function branch member 220 and the state branch member 230 corresponding to the light at the same time.

Thus, the light is irradiated to the outside through the function recognition surface 310 through the functional irradiation surface portion 240 and at the same time through the use state discriminating member 320 denoted as 'UP' via the state irradiation surface 250. Is investigated.

At this time, the light of the light source 10 corresponding to the use state discriminating member 320 denoted as 'UP' is irradiated to the inclined wall surface 130 which is formed symmetrically between the neighboring light sources 10 and is 'DOWN'. It is not irradiated in the direction of use state discriminating member 320 indicated by.

Of course, although not shown, when the light source 10 corresponding to the use state discriminating member 320 indicated as 'DOWN' emits light, the use state discriminating member 320 and the function recognition member 310 located on the opposite side as described above. At the same time guides outward light irradiation.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
