Since the light toward the front is concentrated toward the center of the lens 30 while passing through the lens 30, the light passing through the lens 30 goes straight without interfering with each other.

At this time, since the cooling fan 44 is driven, heat generated from the light source 10 is conducted along the cooling fins 42, and in contact with the air generated by the driving of the cooling fans 44 and the cooling fins 42. Heat is released.

As a result, while the head lamp device is driven for a long time, it is possible to suppress the overheating of the light source 10.

The headlamp device for a vehicle according to the related art has a problem in that a volume and weight of the headlamp device cannot be reduced because a cooling device including a cooling fin and a cooling fan is installed to dissipate heat generated from a light source.

Therefore, there is a need for improvement.

An object of the present invention is to provide a headlamp device for a vehicle that can reduce the volume and weight of a product by simplifying the structure by improving the cooling method, to solve the problems as described above.

In order to achieve the above object, the present invention provides a light source for irradiating light, a reflector for refracting the light irradiated from the light source to the front, the lens refracted by the reflector to go straight without interfering with each other And a cooling block on which the light source, the reflecting plate, and the lens are supported and which emits heat generated from the light source.

In addition, the cooling block of the present invention, the light source, the reflecting plate, the first plate on which the lens is supported, the second plate coupled to the plate to form a predetermined space, the cooling fins provided on the second plate, and the It provides a vehicle headlamp device comprising a cooling water flow path formed between the first plate and the second plate.

In addition, the first plate of the present invention provides a headlamp device for a vehicle, characterized in that the projection provided with the light source is provided.

The headlamp device for a vehicle according to the present invention is provided with a cooling block for supporting a reflector, a lens, and a light source, so that a component that constitutes the headlamp device can be supported without a separate plate, thereby reducing the number of parts and reducing weight. And, since the cooling water is circulated inside the cooling block to achieve a water-cooled cooling device without a separate drive device, the volume, and weight of the product is reduced, there is an advantage that the unit cost of the product is lowered.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of a vehicle headlamp device according to the present invention.

For convenience of description, the headlamp device for a vehicle will be described as an example.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or custom.

Therefore, the definitions of these terms should be based on the contents throughout the specification.

2 is a cross-sectional view showing a headlamp device for a vehicle according to an embodiment of the present invention, Figure 3 is a block diagram showing a headlamp device for a vehicle according to an embodiment of the present invention.

2 and 3, the headlamp device for a vehicle according to an exemplary embodiment of the present invention includes a light source 50 for irradiating light and a reflector for refracting light emitted from the light source 50 to face forward. 60 and a lens 70 for allowing the light refracted by the reflector 60 to go straight without interfering with each other, the light source 50, the reflector 60, and the lens 70 are supported, and the light source 50 is supported. It includes a cooling block 80 for releasing heat generated from.

Thus, when the headlamp device is installed, the headlamp device is assembled by mounting all of the light source 50, the reflector plate 60, and the lens 70 to the cooling block 80 without any supporting member. The number of parts required is reduced.

The cooling block 80 includes a first plate 82 on which the light source 50, the reflecting plate 60, and the lens 70 are supported, and a second plate 84 that is combined with the first plate 82 to form a predetermined space. ), A cooling fin 86 provided on the second plate 84, and a cooling water flow path 88 formed between the first plate 82 and the second plate 84.

Thus, when power is applied to the light source 50 and the light is irradiated, the pump 92 is driven in response to a signal from the controller 90 to circulate the coolant along the coolant flow path 88 to generate heat generated from the light source 50. It will be released to the outside.

In addition, since the heat is secondarily released by the cooling fins 86 formed on the second plate 84, it is possible to suppress overheating of the light source 50 generated by long time use.

The first plate 82 is provided with a protrusion 82a in which the light source 50 is installed. Since the light source 50 is installed on the rear surface of the protrusion 82a, the light emitted from the light source 50 is irradiated to the rear. .

In addition, since the reflecting plate 60 is formed in a panel shape in which bent portions are formed in a plurality of parts, the space required compared with the reflecting plate 20 (see FIG. 1) of the prior art having a curved surface is reduced.

In addition, since the lens 70 uses an aspherical lens corresponding to the polygonal panel reflector 60, it can be seen that the volume of the headlamp device is reduced compared to the technical configuration in which the spherical lens and the curved reflector are installed.

Since the aspherical lens and the polygonal reflector are commonly used structures, descriptions of specific structures and operations will be omitted.

Looking at the operation of the vehicle headlamp device according to an embodiment of the present invention configured as described above are as follows.

First, when assembling the headlamp device, the light source 50 is installed on the protrusion 82a formed on the upper surface of the first plate 82 of the cooling block 80, and the reflective plate 60 and the lens 70 are installed. The assembly of the headlamp device can be completed without the supporting member.

When power is applied to the assembled headlamp device in this manner, light is irradiated from the light source 50, and the light is refracted by the reflector 60 to face forward.

Since light toward the front passes straight through the lens 70 without interfering with each other, the front of the lens 70 can be brightened.

At this time, when power is applied to the light source 50, an electrical signal is transmitted from the controller 90 to drive the pump 92, and thus the cooling water flow path 88 formed between the first plate 82 and the second plate 84. Cooling water is circulated along.

The circulating cooling water absorbs heat generated from the light source 50 and flows to the outside of the head lamp device so that heat is first released. Heat that is not released by the cooling water is conducted to the second plate 84 to be cooled. Released by 86.

As such, the water-cooled heat dissipation action by the cooling water is primarily performed, and the air-cooled heat dissipation action by the cooling fins 86 is secondly, and thus the heat dissipation efficiency is improved.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.

In addition, the headlamp device for a vehicle has been described as an example, but this is merely illustrative, and the headlamp device of the present invention may be used in a product other than the headlamp device used in a vehicle.
