Description

Vehicle rear lamp device using optical fiber

The present invention relates to a rear lamp device of a vehicle, and more particularly to a rear lamp device of a vehicle that can illuminate the rear lamps on both sides of a vehicle by using a single light source.

In general, the lighting device used in a vehicle includes a lighting device for lighting, which is mainly composed of a head lamp, a backup lamp, a room lamp, a brake lamp, and a turn signal lamp. It is divided into equalizer for signal including Turn Signal Lamp and Emergency Lamp and equalizer for external display which consists of Side Lamp, Tail Lamp, and License Plate Lamp. Lose.

In particular, backup lamps, brake lamps, tail lamps, and turn signal lamps mounted on the rear of the vehicle among the lighting devices are usually installed in one case to constitute a rear lamp. Also known as Rear Combination Lamp. Among the lamps constituting the rear lamp, all of the lamps except for the turn signal lamp for displaying the driving direction of the vehicle are configured to simultaneously turn on or blink the lamps installed on the left and right sides of the vehicle.

The rear lamp includes a plurality of bulb socket housings forming bulb bulbs, bulbs respectively mounted on the bulb sockets, connectors coupled to the bulb sockets, and a plurality of cables connecting the connector and the power supply unit. The bulb of the rear lamp is turned on or flashes by turning on and off the driving power supplied to the bulb by the driver's switch operation and the lighting control unit.

However, since the conventional rear lamp requires a plurality of bulbs and a plurality of connectors and cables for supplying power to the bulbs, the rear lamps are not only expensive to manufacture and install, but also light a plurality of bulbs. In order to consume a lot of power, and occupy a lot of internal space of the vehicle, there was a problem of reducing the efficiency of space utilization.

In order to solve the above problems, an object of the present invention is to provide a rear lamp device of a vehicle using an optical fiber in order to maximize power consumption and space consumption by using a minimum light source.

In order to achieve the above object, the present invention is a rear lamp device of a vehicle, comprising: a light source unit which is turned on by the input of a driving voltage and emits light, and a lens which is attached to the front and installed at both rear ends of the vehicle One end is fixed to the housing and the light source so that the cross section is facing, and the other end surface comprises a plurality of optical fibers attached to the lenses of both lamp housings.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a schematic diagram of a rear lamp device of a vehicle using an optical fiber according to a preferred embodiment of the present invention, Figure 2 is a cross-sectional view of the AA 'portion of Figure 1, Figure 3 is a rear using an optical fiber according to an embodiment of the present invention Side sectional view of the lamp.

As shown in FIGS. 1 to 3, the rear lamp device of the vehicle according to the embodiment of the present invention is largely composed of a light source unit 10, an optical cable 20, and a rear lamp 40.

The light source unit 10 includes a bulb housing 14 having one side opened, a bulb 12 mounted inside the bulb housing, and the rear lamp 40 includes a lamp housing 42 and a lens 44 attached to a front surface of the lamp housing.

The optical cable 20 includes a flexible tubular jacket 26, a plurality of optical fibers 30 embedded in the jacket, and a housing cylinder 22 and a lamp cylinder 24 coupled to both ends of the jacket, in particular, the optical fiber 20 transmits light. And a coating layer 34 surrounding the outer circumferential surface of the nucleus to prevent the loss of light passing through the nucleus.

In addition, the housing cylinder 22 is installed at the opened front of the bulb housing 14 so that the cross section of the optical fiber is toward the bulb front, and the lamp cylinder 24 is installed at the rear of the lamp housing 42 to project the cross section of the optical fibers of the lens 44 Attach to the back.

Referring to the operation of the rear lamp device of the vehicle using the optical fiber according to the embodiment of the present invention coupled as described above are as follows.

When the driving voltage is supplied to the bulb 12 by the driver's switch operation and the light control unit and the bulb 12 is turned on, the light emitted from the bulb 12 is incident into the optical fiber through the optical fiber 30 cross section in the housing cylinder 22. Subsequently, light incident through one end of the optical fiber 30 is transmitted through the nucleus 32 of the optical fiber 30, and is transmitted to the other end of each optical fiber 30 attached to the lens 44 of the rear lamp 40. At this time, since the light is emitted to the outside through the other end of each optical fiber 30 attached to the lens 44, it is possible to enjoy the same effect as the light is turned on the entire lens 44 of the rear lamp 40.

Meanwhile, as described above, the rear lamp includes a backup lamp, a brake lamp, a tail lamp, and a turn signal lamp, and all of the lamps except for the turn signal lamp for indicating the driving direction of the vehicle are located on the left and right sides of the vehicle. Since each of the lamps are to be turned on or flashing at the same time, if one light source for each lamp is provided, the left and right lamps can be turned on simultaneously.

As described above, the rear lamp device of the vehicle using the optical fiber according to the embodiment of the present invention has a small space occupied in the vehicle, which is advantageous for space utilization, and can drive both rear lamps by driving only one light source to consume power. Has the effect of reducing.
