1 is a perspective view schematically illustrating a configuration of a lamp for a vehicle according to an embodiment of the present invention, and FIG. 2 is a front view of the main light source module and the sub light source module in FIG. 1 .

As shown, the vehicle lamp 100 according to an embodiment of the present invention may be configured to include light source modules 110 , 120 , 130 , a shield member 200 , and a lens 300 .

For reference, the vehicle lamp 100 in the embodiment of the present invention will be described as an example in the case of a head lamp that enables a front view to be secured when driving in a dark place such as night driving or tunnel driving, The present invention is not limited thereto, and the vehicle lamp according to an embodiment of the present invention may be various lamps such as a fog lamp, a tail lamp, a brake lamp, a position lamp, and a turn signal lamp installed in a vehicle.

The light source modules 110 , 120 and 130 may include at least one main light source module 110 and at least one sub light source module 120 , 130 .

Here, the main light source module 110 and the sub light source modules 120 and 130 may be disposed at different heights from each other.

For example, when the main light source module 110 is disposed near the optical axis Ax or the optical axis, the sub light source modules 120 and 130 are disposed below the optical axis with respect to the vertical direction and are lower than the main light source module 110. can be placed.

For reference, in the embodiment of the present invention, the main light source module 110 is disposed on the upper side with respect to the vertical direction and the sub light source module 120, 130 is disposed on the lower side as an example, but it is not limited thereto, The sub light source modules 120 and 130 may be disposed above the main light source module 110 .

In addition, when the main light source module 110 is disposed near the optical axis Ax or the optical axis, the sub light source modules 120 and 130 are left with respect to the main light source module 110 in a horizontal direction intersecting the optical axis Ax direction. Or, it may be disposed at any one position among the right.

Here, the sub light source modules 120 and 130 may be disposed to face each other on the left and right with respect to the main light source module 110 in a horizontal direction intersecting the optical axis Ax direction.

Meanwhile, the main light source module 110 includes at least one first light source 112 and a first reflector 114 that reflects the light generated from the first light source 112 and transmits it to the lens 300 . It may consist of

In addition, the sub light source modules 120 and 130 include at least one second light source 122 and a second reflector 124 that reflects the light generated from the second light source 122 and transmits it to the lens 300 . The first sub light source module 120 , at least one third light source 132 , and a third reflector 134 that reflects the light generated from the third light source 132 and transmits it to the lens 300 .

The included second sub light source module 130 may be provided as a pair. In this case, the first sub light source module 120 and the second sub light source module 130 are aligned in the optical axis direction with respect to the main light source module 110 . They may be disposed on the left and right, respectively, based on the intersecting horizontal direction.

When the first sub light source module 120 and the second sub light source module 130 constituting the sub light source modules 120 and 130 are disposed on the left and right sides of the main light source module 110, respectively, the first sub light source module 120 and the second sub light source module The two sub light source modules 130 may be disposed at the same height in the vertical direction or may be disposed at different heights.

Meanwhile, the main light source module 110 and the sub light source modules 120 and 130 may be installed in a structure supported by one base plate 150 .

Accordingly, the base plate 150 is disposed on both sides of the first plate 152 and the first plate 152 in which the central portion is disposed at a relatively high position, but at a position relatively lower than that of the first plate 152 . The second plate 154 and the third plate 156 disposed on may be configured in a stepped shape.

An insulating layer is formed on one surface of the base plate 150 , that is, one surface on which the first light source 112 of the main light source module 110 and the second light source 122 and the third light source 132 of the sub light source modules 120 and 130 are seated. 158 is coated, and at least one connector (not shown) is disposed on one side of the base plate 150 , so that the first light source 112 of the main light source module 110 and the second light source module of the sub light source modules 120 and 130 are disposed.

In addition, the connector may increase/decrease the amount of light of the first light source 112 , the second light source 122 , and the third light source 132 .

In this way, since the first light source 112 of the main light source module 110 and the second light source 122 and the third light source 132 of the sub light source modules 120 and 130 can be simultaneously controlled by one connector, Since the control logic is simplified, the design is simplified, and thus the number of parts is reduced, thereby providing an effect of reducing the manufacturing cost.

The first light source 112 of the main light source module 110 may have a larger amount of light than the second light source 122 and the third light source 132 of each of the sub light source modules 120 and 130 . In this case, the first light source 112 of the main light source module 110 has an amount of light at least three times greater than that of the second light source 122 and the third light source 132 of each sub light source module 120 and 130 . desirable.

For example, when the light amount of the second light source 122 and the third light source 132 of each sub light source module 120 and 130 is 270 lumens (lm), the light amount of the first light source 112 of the main light source module 110 is By applying about 1000 lumens (lm), the first light source 112 of the main light source module 110 is at least 3 compared to the second light source 122 and the third light source 132 of each sub light source module 120 and 130 . It can be made to have more than double the amount of light.

At this time, if the first light source 112 provided to the main light source module 110 and the second light source 122 and the third light source 132 provided to the sub light source modules 120 and 130 have the same amount of light, the main The light source module 110 may be provided with three times the number of the first light sources 110 than the number of the second light sources 122 or the third light sources 132 provided to the sub light source modules 120 and 130 .

In addition, the first light source 110 provided to the main light source module 110 has a light quantity three times or more than that of the second light source 122 or the third light source 132 provided to the sub light source modules 120 and 130. It may be provided as a light source.

In this way, the amount of light of the first light source 110 provided to the main light source module 110 is greater than the light amount of the second light source 122 and the third light source 132 provided to the sub light source modules 120 and 130 . The reason for application is that, when the lamp is on, such as during night driving or tunnel driving, the light generated from the first light source 110 of the main light source module 110 always passes through the lens and irradiates to the outside. This is because it forms a specific beam pattern, which will be described in detail later.

For reference, the first light source 112 of the main light source module 110 and the second light source 122 and the third light source 132 of the sub light source modules 120 and 130 applied to the embodiment of the present invention are semiconductor light emitting diodes. A light emitting diode (LED), which is a device, may be applied, and in some cases, various types of light sources such as a bulb and a laser may be applied.

The shield member 200 is formed in a flat plate shape and may be positioned near the optical axis Ax or the optical axis, and the front end both sides are gradually displaced toward both sides of the lens 300 along the rear focal plane of the lens 300. Curve shape to be formed so that at least a portion of a surface that blocks some light generated from the main light source module 110 and the sub light source modules 120 and 130 has a step difference to form a cut-off line according to the beam pattern can

The shield member 200 may be rotatably driven by a predetermined angle by a driving means such as an actuator (not shown). For example, as it is driven by a driving means such as an actuator, it is possible to change the position to the shielding position and the non-shielding position, and accordingly, various beam patterns can be formed while the change of the beam pattern is generated. This will also be described in detail later. decide to do

The lens 300 may be disposed in front of the shield member 200 and may irradiate light passing through the shield member 200 and light reflected by the shield member 200 to the outside, and may vary according to the light irradiation range.
