Description

Lamp for vehicle

Technical Field

The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp in which a high beam pattern and a low beam pattern are formed by one module.

Background

In general, a vehicle is equipped with various kinds of lamps having a lighting function for easily checking an object located in the periphery of the vehicle during night driving and a signaling function for informing a driver of another vehicle or a road pedestrian of the driving state of the vehicle.

For example, headlamps (Head lamps) and Fog lamps (Fog lamps) are provided for the main purpose of lighting functions, turn signals (Tail lamps), brake lamps (Brake lamps), side Marker lamps (Side Marker) and the like are provided for the purpose of signal functions, and regulations prescribe the setting standards and specifications of these lamps to fully exert the respective functions thereof.

The headlight forms a low beam pattern or a high beam pattern so that a driver's front view can be ensured when the vehicle is driven in a dark surrounding environment such as at night, and it plays a very important role in safe driving.

In addition, in the case where a low beam module forming a low beam pattern and a high beam module forming a high beam pattern are additionally provided and arranged in a vehicle, a space for the low beam module and the high beam module is additionally provided, and thus space inefficiency may occur. In addition, additional components for the respective modules are required, and thus manufacturing costs may also increase.

Therefore, there is a need for a vehicle light fixture in which the modules forming the low beam pattern and the high beam pattern are implemented as one body.

The interval between adjacent ones of the plurality of second light sources 211 may be formed to be larger from the center toward the edge. As described with reference to fig. 13, n2 may be formed to be greater than n1 and n3 may be formed to be greater than n2.

The second light source 211 arranged at the center of the plurality of second light sources 211 may irradiate light to a center region of the second beam pattern, and the second light source 211 arranged at the edge of the plurality of second light sources 211 may irradiate light to an edge region of the second beam pattern. The interval between the second light sources 211 arranged at the center among the plurality of second light sources 211 is smaller than the interval between the second light sources 211 arranged at the edge, so light may be concentrated toward the center region of the second beam pattern.

The length of the ARC2 formed by the plurality of second light sources 211 (hereinafter, referred to as a second ARC length) may be formed to be smaller than the length of the ARC1 formed by the plurality of first light sources 111 (hereinafter, referred to as a first ARC length). The distance between the second light sources 211 disposed at both side ends among the plurality of second light sources 211 may be smaller than the distance between the first light sources 111 disposed at both side ends among the plurality of first light sources 111. Further, the second curvature of the ARC2 formed by the plurality of second light sources 211 may be formed to be greater than the first curvature of the ARC1 formed by the plurality of first light sources 111.

As the second arc length is formed smaller than the first arc length and the second curvature is formed larger than the first curvature, the plurality of second light sources 211 may concentrate light to a smaller area with respect to the plurality of first light sources 111 to form a beam pattern. Accordingly, as shown in fig. 5, the high beam pattern HP has a small size compared to the low beam pattern LP. The high beam pattern HP may provide a night vision for a longer distance as light is concentrated to a relatively small area.

Fig. 14 is a plan view of the second reflector.

Referring to fig. 14, the second reflector 220 may include a plurality of second reflecting parts 221. The plurality of second reflecting portions 221 may reflect the second light irradiated from the plurality of second light sources 211.

The second reflector 220 may include a shield bond 222. The shield coupling portion 222 may be provided for coupling of the shield 130. For example, the shield coupling 222 may include bolt holes, and the shield 130 may be coupled to the shield coupling 222 using bolts.

Referring to fig. 15, the first beam pattern forming part 100 and the second beam pattern forming part 200 may be arranged at different heights from each other.

The first beam pattern forming part 100 may be disposed at a position higher than the second beam pattern forming part 200. The first light irradiated from the first beam pattern forming part 100 may be transmitted through the lens 400 and irradiated in a downward direction, thereby forming a first beam pattern, and the second light irradiated from the second beam pattern forming part 200 may be transmitted through the lens 400 and irradiated in an upward direction, thereby forming a second beam pattern.

Fig. 16 is a perspective view of the heat sink.

Referring to fig. 16, the heat sink 300 includes a first heat sink 310, a second heat sink 320, and heat sink fins 330.

The first heat dissipation plate 310 may be closely attached to the first light source part 110 to absorb heat of the first light source part 110. The second heat dissipation plate 320 may be closely attached to the second light source part 210 to absorb heat of the second light source part 210.

The first heat dissipation plate 310 and the second heat dissipation plate 320 may be disposed at different heights from each other. Specifically, the first heat dissipation plate 310 may be disposed at a position higher than the second heat dissipation plate 320. The first heat dissipation plate 310 and the second heat dissipation plate 320 may be arranged in a stepped shape. That is, the first heat sink 310 and the second heat sink 320 may have different heights and different distances from the lens 400. In the present invention, a distance between the first heat dissipation plate 310 and the lens 400 may be greater than a distance between the second heat dissipation plate 320 and the lens 400. In addition, according to several embodiments of the present invention, a distance between the first heat dissipation plate 310 and the lens 400 may be smaller than a distance between the second heat dissipation plate 320 and the lens 400.

As described above, the first beam pattern forming part 100 and the second beam pattern forming part 200 may be arranged at different heights from each other. That is, the first light source part 110 and the second light source part 210 may be disposed at different heights from each other, and specifically, the first light source part 110 may be disposed at a position higher than the second light source part 210. The first and second

light source parts

110 and 210 may be disposed closely to the first and second

heat dissipation plates

310 and 320, and the heights of the first and second

light source parts

110 and 210 may be determined by the first and second

heat dissipation plates

310 and 320.

The heat dissipation fins 330 may discharge heat of the first heat dissipation plate 310 and the second heat dissipation plate 320 to the outside. The heat dissipation fins 330 may be provided in plurality and provided to the first heat dissipation plate 310 and the second heat dissipation plate 320. The plurality of heat radiating fins 330 may be arranged at a predetermined interval from each other. Accordingly, the heat transferred to the respective heat radiating fins 330 can be discharged to the outside through the spaces between the heat radiating fins 330.

The heat radiating fins 330 may be exposed to the outside through heat radiating holes 521 provided in the lower bracket 520. The heat of the heat radiating part 300 may be discharged to the outside of the bracket 500 by the heat radiating fins 330.

As the heat dissipation of the first and second

light source parts

110 and 210 is performed by one heat dissipation part 300, the configuration of the lamp module 20 can be simplified and the assembly time can be shortened.

Fig. 17 is a perspective view of a lens.

Referring to fig. 17, the lens 400 may include a light transmitting part 410 and an insertion coupling part 420.

The light transmitting portion 410 may transmit light irradiated from the first and second beam

pattern forming portions

100 and 200. Specifically, the light transmitting part 410 may transmit the first light reflected by the first reflector 120 and the second light reflected by the second reflector 220.

The insertion coupling portion 420 may be inserted into and coupled to the

coupling grooves

512, 522 provided in the bracket 500. As the insertion coupling portion 420 is inserted into the

coupling grooves

512, 522, the lens 400 may be fixed to the bracket 500. The insertion bonding portion 420 may be formed along an edge of the light transmitting portion 410. For example, the insertion coupling part 420 may be formed in a ring shape along the edge of the light transmitting part 410.

The insertion coupling portion 420 may be formed to protrude outward from the light transmitting portion 410. Therefore, the light transmitting portion 410 can transmit light of the first and second beam

pattern forming portions

100 and 200 without interfering with the

coupling grooves

512 and 522 of the bracket 500.

Referring to fig. 18, the first beam pattern forming part 100 may irradiate light for forming a first beam pattern.

The light irradiated from the first light source 111 may be reflected by the first reflection part 121 and transferred to the lens 400. The light transmitted through the lens 400 may be used to form a first beam pattern while being irradiated in a downward direction.

Referring to fig. 19, the second beam pattern forming part 200 may irradiate light for forming the second beam pattern.

The light irradiated from the second light source 211 may be reflected by the second reflecting part 221 and transferred to the lens 400. The light of the transmission lens 400 is irradiated in an upward direction, so that it can be used to form a second beam pattern.

Hereinafter, a process of manufacturing the lamp module 20 will be described. The case where the lower bracket 520 is provided with the inner bottom surface of the lower bracket 520 facing upward will be mainly described.

Referring to fig. 20, the heat sink 300 may enter toward the lower bracket 520. The heat sink 300 may be mounted to the lower bracket 520 without a separate fixture.

Referring to fig. 21, the second light source unit 210 and the second reflector 220 may enter toward the lower bracket 520.

After the second light source part 210 is stacked on the heat sink part 300, the second reflector 220 may be stacked on the second light source part 210.

The second reflector 220 may be bolted to the lower bracket 520 using bolts BT. In a state where the heat radiation portion 300, the second light source portion 210, and the second reflector 220 are stacked in this order, as the second reflector 220 is screw-coupled to the lower bracket 520, all of the heat radiation portion 300, the second light source portion 210, and the second reflector 220 may be fixed to the lower bracket 520.

Referring to fig. 22, the first light source 110 and the shield 130 may enter toward the lower bracket 520.

The first light source part 110 may be stacked on the heat sink part 300, and the shielding member 130 may be stacked on the second reflector 220. The shield 130 may be coupled to the second reflector 220. Specifically, the shield 130 may be bolt-coupled to the shield coupling portion 222 of the second reflector 220 using the bolt BT. The shield 130 may be fixed to the lower bracket 520 by the second reflector 220.

The insertion coupling part 420 provided on the lens 400 may be inserted into the coupling groove 522 provided at the lower bracket 520 to perform the insertion coupling between the lens 400 and the lower bracket 520.

Referring to fig. 25, the upper bracket 510 may be accessed toward the lower bracket 520.

While the upper bracket 510 may be closely attached to the lower bracket 520, the locking protrusion 513 of the upper bracket 510 may be inserted into the locking portion 523 of the lower bracket 520, and simultaneously locking coupling between the upper bracket 510 and the lower bracket 520 may be performed. Further, the upper bracket 510 may be bolt-coupled to the lower bracket 520 using a bolt BT. The upper bracket 510 and the lower bracket 520 may be coupled to each other in a snap-coupling and bolt-coupling manner.

With the upper bracket 510 coupled to the lower bracket 520, the first reflector 120 may be pressed and fixed to the upper bracket 510.

The lens 400 may be pressed and fixed to the holder 500 by the upper and

lower holders

510 and 520. Since a separate coupling unit is not used, assembly of the lens 400 can be more easily performed.
