Description

Lamp module {LAMP MODULE}

The present invention relates to a lamp module, and more particularly to a lamp module that improves cooling performance while reducing its own weight and volume.

In general, the automotive lamp module is provided with a cooling device for heat dissipation of the LED used as a lamp, Figure 1 is a schematic configuration diagram of a conventional automotive lamp module.

Referring to FIG. 1, the lamp module 10 includes a lens 12 and a lamp 13 in the housing 11 to irradiate light in one direction.

That is, the housing 11 is opened in one direction to irradiate light in one direction, and the lens 12 is mounted to the opened portion to transmit light.

In addition, the LED lamp 13 is provided at a position spaced apart from the lens 12 by a predetermined distance to generate light. At this time, the reflective material is applied or adhered to the inner surface of the housing 11 so that the light of the lamp 13 is reflected to pass through the lens 12. On the other hand, the housing 11 may be integrally formed, or may be divided into a portion having a reflective material and a portion not having a reflective material and joined.

Since the lamp 13 is heated due to the generation of light, it is necessary to quickly discharge the generated heat. To this end, a heat radiation fin 14 in contact with the lamp 13 is provided. The heat dissipation fins 14 are designed to have a sufficient volume to increase surface contact with air.

In addition, the heat radiation fan 15 is further provided to improve the heat radiation efficiency of the lamp 13. The heat dissipation fan 15 discharges air in the direction of the heat dissipation fins 14 so that the heat dissipation fins 14 are cooled quickly.

Meanwhile, the heat dissipation fan 15 is installed on the support plate 16, and one end of the support plate 16 is coupled to the outer circumferential surface of the housing 11.

Therefore, when the lamp 13 is turned on, heat generated from the lamp 13 is conducted to the heat radiation fins 14 to escape into the air. Then, the heat conducted to the heat radiating fins 14 by the heat radiating fan 15 quickly exits into the air.

However, since the heat dissipation fin is provided only in a portion in contact with the lamp, there is a problem that the volume of the heat dissipation fin is increased for effective heat dissipation.

For this reason, there is a problem in that the size of the lamp module itself is increased and the weight and cost are increased.

Therefore, there is a need for improvement.

The present invention has been made to solve the above problems, and an object thereof is to provide a lamp module with a reduced volume.

In order to achieve the above object, the present invention is a housing that is open in one direction; A lens provided in the opened portion of the housing; A lamp mounted to the housing to irradiate light to the lens; A heat dissipation fin integrally provided on an outer circumferential surface of the housing; It provides a lamp module comprising a heat dissipation fan for discharging air to the heat dissipation fins.

Inside the housing is characterized in that the reflective surface for reflecting light in the direction of the lens is provided.

The heat dissipation fan is mounted to the heat dissipation fin close to the lamp.

As described above, the lamp module according to the present invention has an effect that the heat dissipation fin is integrally formed in the housing, thereby reducing the manufacturing cost of the module itself and reducing its own volume.

In addition, the lamp module according to the present invention is provided with a plurality of heat dissipation fins at predetermined intervals in the housing, thereby improving cooling performance.

Hereinafter, an embodiment of a lamp module according to the present invention will be described with reference to the accompanying drawings.

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

2 is a schematic configuration diagram of a lamp module according to an embodiment of the present invention.

2, the housing 21 of the lamp module 20 has a shape in which one direction is opened. In addition, the lens 22 is provided at the opened portion of the housing 21.

The housing 21 is provided with a lamp 23. The lamp 23 uses a light emitting diode (LED). The lamp 23 irradiates light toward the lens 22.

The heat dissipation fin 24 is integrally provided on the outer circumferential surface of the housing 21. That is, a plurality of heat dissipation fins 24 protrude at predetermined intervals on the outer circumferential surface of the housing 21 to cool the heat generated by the lamp 23. To this end, the housing 21 including the heat dissipation fins 24 is molded of a material having excellent thermal conductivity. On the other hand, the lamp 23 is designed to be in contact with the housing 21 so that the heat generated in the lamp 23 is conducted to the heat radiation fins 24. The housing 21 may be divided into a part in which the lens 22 is provided and a part in which the lamp 23 is provided, and may be coupled to each other.

The heat dissipation fins 24 are mounted to the heat dissipation fins 24. The heat dissipation fan 25 discharges air toward the heat dissipation fins 24 to forcibly cool the heat dissipation fins 24. The heat dissipation fan 25 is mounted to the heat dissipation fins 24 proximate to the lamp 23.

The inner surface of the housing 21 is provided with a reflective surface 26 so that the light irradiated from the lamp 23 is reflected in the direction of the lens 22. This reflective surface 26 suppresses the loss of light generated by the lamp 23. In addition, the reflective surface 26 allows the light generated by the lamp 23 to be moved toward the lens 22 even when the lamp 23 is not positioned in line with the lens 22.

On the other hand, the lamp 23 and the heat dissipation fan 25 is operated by being supplied with a power not shown.

Referring to the operation of the lamp module according to an embodiment of the present invention having the structure as described above are as follows.

When the lamp 23 is lit, the light is moved toward the lens 22 through the reflecting surface 26. The lamp 23 itself is heated by the lighting of such a lamp 23.

When the lamp 23 is heated, heat is conducted to the housing 21 in contact with the lamp 23, and the heat is cooled by the heat dissipation fin 24 integrally formed on the outer circumferential surface of the housing 21. That is, heat generated by the lamp 23 is cooled by the air.

On the other hand, the heat radiating fan 25 forcibly discharges air toward the heat radiating fins 24, thereby rapidly cooling the heat conducted to the heat radiating fins 24.

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.

Therefore, the true technical protection scope of the present invention will be defined by the claims below.
