The present invention relates to an engine room lighting apparatus, and more particularly, to an engine room lighting apparatus capable of illuminating a complex engine room interior using an optical fiber.

Generally, when checking the engine room of a vehicle, a separate portable lighting device such as a flashlight is used to look at every corner of the engine room at night as well as during the day.

However, as described above, there is a hassle of having to prepare and store a portable lighting fixture at all times, and the engine room maintenance work is inconvenient as well as a hand because the portable lighting fixture must be held in one hand and the engine room must be checked with the other hand. There is a high risk of a safety accident, such as injury.

On the other hand, as shown in Figure 1, the engine room hood 4 is provided with a lighting device 6 using an illumination lamp or a reflector, etc. In general, the engine room inspector is the engine room (2) Since the body bends toward the engine room 2 to look in, the light of the lighting device 6 is obscured, which does not help much.

The present invention has been made to solve the above problems of the prior art, by being configured so that the interior of the engine room can be illuminated using the optical fiber, not only can the engine room maintenance efficiency can be improved, but the optical fiber is complex inside the engine room It is an object of the present invention to provide an engine room lighting apparatus that can be easily installed in the.

Engine room lighting apparatus according to the present invention for solving the above problems is a light source; Is installed inside the engine room is connected to the light source, characterized in that configured to include an optical fiber having at least one hole so that light can be emitted.

The engine room lighting apparatus may further include a reflector provided at an end of the optical fiber that is not connected to the light source.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3.

Figure 2 is a perspective view showing an embodiment in which the engine room lighting apparatus according to the present invention is applied, Figure 3 is a schematic diagram showing the configuration of the engine room lighting apparatus according to the present invention, Figure 4 is an engine room lighting apparatus according to the present invention The figure shows the lighting action.

The engine room lighting apparatus according to the present invention is installed in the vehicle body 10 and is connected to the light source 20 to provide light of a specific wavelength range, and to receive the light of the light source 20 and Including an optical fiber 30 is installed along the inner edge of the engine room 12 and formed with at least one hole 31 so that light transmitted from the light source 20 can be emitted into the engine room 12. It is composed.

The light source 20 includes a sealed box 22 through which light cannot pass, a lamp 24 provided inside the sealed box 22 to emit light in a specific wavelength range, and the lamp 24 lights up. And a lamp power supply unit 26 for supplying power to the lamp 24 and a lamp power supply switch 28 for selectively supplying power of the lamp power supply 26 to the lamp 24.

The sealed box 22 is formed with a sealed box hole 22a so that the light emitted from the lamp 24 can be transmitted to the optical fiber 30.

The sealed box hole 22a of the sealed box 22 is provided with a connector 40 for connecting the sealed box 22 and the optical fiber 30.

The lamp 24 may be implemented as a light emitting diode (LED) or the like.

The lamp power switch 28 may be installed in the instrument panel 11 in the vehicle compartment to enable manual operation.

That is, the lamp power supply switch 28 may be provided to operate in two modes of ON / OFF, and in the on mode, the power of the lamp power supply 26 is applied to the lamp 24. In the off mode, power of the lamp power supply unit 26 is not applied to the lamp 24.

The optical fiber 30 has a core 32 through which the light of the light source 20 is transmitted by total reflection or refraction, and the light transmitted through the core 32 is leaked out by being covered outside the core 32. It consists of a cladding 34 which blocks the thing and a sheath 36 covered on the outside of the cladding 34.

The optical fiber 30 has a hole 31 so that light transmitted through the core 32 of the optical fiber 30 can pass through the cladding 34 and the sheath 36 of the optical fiber 30. The cladding 34 and sheath 36 of 30 may be formed by damage.

The optical fiber 30 configured as described above is provided with a spot light unit 30a connected to the light source 20 through the connector 40 and a hole 31 of the optical fiber 30. The side light may be divided into a side light unit 30b.

The optical fiber 30 provided as described above may be installed at the left and right edges of the engine room 12 so as to evenly illuminate the inside of the engine room 12.

At this time, one end of the optical fiber 30 is connected to the light source 20 and the other end is an open loop type. Of course, the optical fiber 30 may be provided in a closed type with respect to the light source 20.

On the other hand, at the open end of the optical fiber 30, the light of the light source 20 to the open end of the optical fiber 30 through the core 32 of the optical fiber 30 to minimize the light source loss After being delivered, a reflector 38 may be provided to allow it to be delivered again through the core 32 of the optical fiber 30.

Looking at the operation of the present invention configured as described above are as follows.

When the lamp power supply switch 28 is operated in the on mode, the power of the lamp power supply 26 is applied to the lamp 24, and the lamp 24 emits light of a specific wavelength band.

Light emitted from the lamp 24 is transmitted to the optical fiber 30 through the connector 40. In addition, the light transmitted to the optical fiber 30 leaks out of the optical fiber 30 through the hole 31 of the optical fiber 30, so that the engine room 12 may be illuminated.

Engine room lighting apparatus according to the present invention configured as described above has the advantage that the engine room maintenance efficiency can be improved because it can illuminate the inside of the engine room using the optical fiber.

In addition, since the optical fiber is manufactured to be relatively light and slim because it is like a thin thread of about 125 μm, it can be easily installed and repaired no matter how complicated the inside of the engine room is. There is no need to change, and the structure has a simple advantage.

In addition, since the optical fiber is made of quartz extracted from the sand, it is environmentally friendly, and because it uses light, electromagnetic waves are not generated, and electricity and heat do not pass.

In addition, the engine room lighting apparatus according to the present invention is less power consumption, maintenance costs are much cheaper than before, and the maintenance costs are economically advantageous.
