According to an aspect of the present invention, there is provided an illumination device for an automobile, the illumination device including: a light source for generating light; and a light source mounting part for mounting the light source so that the light source can emit the light in a predetermined direction. And a heat sink coupled to the flexible substrate to allow the light source mounting portion to maintain bending.

The details of other embodiments are included in the detailed description and drawings.

The light source mounting portion of the flexible substrate on which the light source is mounted is bent in a predetermined direction and the heat sink coupled to the flexible substrate maintains bending of the light source mounting portion, The light generated by the light source can be emitted in the predetermined direction without the need for such a separate member so that the weight of the lighting apparatus is reduced, the number of operations is reduced, and the size is compact.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned may be clearly understood by those skilled in the art from the description of the claims.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to accomplish them, will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. It should be understood, however, that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Is provided to fully inform the owner of the category of design, and the design is only defined by the scope of the claim. Like reference numerals refer to like elements throughout the specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a vehicle lighting apparatus according to an embodiment of the present invention will be described with reference to the drawings.

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a view showing an automotive lighting apparatus according to an embodiment of the present invention; FIG.

Referring to FIG. 1, an automotive lighting apparatus according to an embodiment of the present invention includes a light source 10 for generating light, and a flexible printed circuit board (FPCB) 20 having a light source mounting portion 25 on which a light source is mounted. A heat sink 30 coupled to the flexible substrate 20 for cooling the heat generated by the light source 10 and an LDM (LED Driver Module) ASM 40 coupled to the heicink 30 do.

The light source 10 is formed of a light emitting diode (LED). A plurality of light sources 10 are provided and coupled to the front surface of the flexible substrate 20.

In the flexible substrate 20, a plurality of light source mounting portions 25 corresponding to the plurality of light sources 10 are formed. One light source 10 is mounted on the light source mounting portion 25.

The light source mounting portion 25 is formed by cutting the flexible substrate 20 and bending it in a predetermined direction. The light source mounting portion 25 is formed such that the left side and the upper and lower sides in the drawing are cut away from the flexible substrate 20 and only the right side is attached to the flexible substrate 20. [ The light source mounting portion 25 is bent so that the left side protrudes forward with respect to the right side attached to the flexible substrate 20, and is disposed so as to gradually protrude forward from the right side to the left side.

A square hole 22 is formed in the lower right end of the light source mounting portion 25. The square hole 22 allows the flexible substrate 20 to bend easily when the light source mounting portion 25 is bent forward. The square hole 22 is covered by a heat sink 30 coupled to the rear surface of the flexible substrate 20.

The light source mounting portion 25 is bent in a predetermined direction so that the light source 10 coupled to the light source mounting portion 25 can emit the generated light in a predetermined direction.

The heat sink 30 is coupled to the flexible substrate 20 so that the light source mounting portion 25 can maintain bending. The heat sink 30 is formed of an aluminum material having excellent heat dissipation performance because the heat sink 30 needs to cool the heat generated by the light source 10 although the heat sink 30 can be formed harder than the flexible substrate 20. [ .

The heat sink 30 is coupled to the rear surface of the flexible substrate 20, which is the opposite surface of the front surface on which the light source 10 is mounted.

The heat sink 30 includes a flexible substrate coupling portion 32 to be coupled to the rear surface of the flexible substrate 20 and an LDM coupling portion 34 formed to be bent from the flexible substrate coupling portion 32.

The flexible substrate coupling portion 32 is formed with a first coupling protrusion 31 inserted into and coupled to the flexible substrate 20 and a second coupling protrusion 33 inserted into the light source mounting portion 25 to be coupled thereto. Of course, the flexible substrate 20 is provided with a first coupling hole 21 into which the first coupling projection 31 is inserted and a second coupling hole 21 into which the second coupling projection 33 is inserted, 23 are formed. The first coupling protrusion 31 is inserted into the first coupling hole 21 to be coupled with the flexible substrate 20 and the second coupling protrusion 33 is inserted into the second coupling hole 23, Lt; / RTI >

The portion of the flexible substrate coupling portion 32 coupled with the light source mounting portion 25 is incised and bent in correspondence with the light source mounting portion 25. [ However, the portion corresponding to the square hole 22 formed in the flexible substrate 20 is not cut so that the square hole 22 is covered from the rear side.

The LDM coupling portion 34 is bent forward in the flexible substrate coupling portion 32 and protrudes to the lower side of the flexible substrate 20. Two LDM coupling portions 34 are formed. An LDM array 40 is coupled to the right side of the two LDM joining parts 34.

The LDM array 40 includes a current circuit for supplying current to a plurality of light sources 10. A power connector 45 is provided at one side of the LDM array 40 so as to supply current to the plurality of light sources 10.

The LDM array 40 may be bolted to the LDM coupling part 34 while being seated on the upper side of the LDM coupling part 34 in front of the flexible substrate 20. [ It is preferable that the upper surface of the LDM array 40 is disposed at a lower position than the light source mounting part 25 so as not to block the light generated by the plurality of light sources 10. [

As described above, in the automotive lighting apparatus according to the present invention, the light source mounting portion 25 of the flexible substrate 20 on which the light source 10 is mounted is bent in a predetermined direction, and the heat sink The light generated by the light source 10 can be emitted in the predetermined direction without a separate member such as a back cover because the light source unit 30 maintains the bending of the light source mounting unit 25, The workload is reduced and the size becomes compact.

Those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative and non-restrictive in every respect. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all changes or modifications derived from the meaning and scope of the claims and equivalents thereof are included in the scope of the present invention Should be interpreted.
