In general, a navigation light is used to enable a ship to know the position and condition of a ship at night or during limited visibility due to fog or smoke, and to allow an outside person to predict the direction of the ship. It is installed on the front and back and left and right of the ship. Depending on the length of the ship, there are 1 and 2 species, and depending on the installation position, it is divided into a bow, a light, a stern. Usually, In the case of the stern and so on, the light of white color is illuminated within the irradiation angle range of 135 ° so that the direction of the ship is illuminated during night voyage, To prevent accidents in advance.

However, most of marine navigation light such as incandescent lamps such as filament or halogen is used or light emitting diode (LED) is used. According to the international navigation standard, it is supplied with electric power of 200 W or more, The life of the filament is shortened due to the high heat due to the long period of time, and in the case of the light emitting diode (LED), the life is shortened and the illumination is also dark.

Due to such a problem, the heat dissipating from the light source is dissipated to the outside through a large number of heat dissipation holes on the bottom of the navigation light, but the seawater easily penetrates into the heat dissipating hole by the waves during the sailing process, Which shortens the life span and causes electric short-circuit, which is a cause of fire.

Accordingly, a method for improving the longevity of a navigation light for a marine LED, known as a patent application 10-2010-0097320, and an LED navigation light for a marine navigation using the method are disclosed and disclosed in Japanese Patent Application Laid- Chip LED package is used as a light source so that only a part of a plurality of LED chips in each multi-chip LED package is lit when the navigation light is lit, whereby the luminance per unit area is obtained by lighting all of the plurality of LED chips But the heat generation amount can be greatly reduced as compared with a case where a plurality of LED chips are all lit, so that it is possible to prevent the luminous efficiency and the life of the LED chip due to heat generation. Inefficient room where only a few LED chips should be lit As the non-fundamental radiation of heat, and the light source is limited to the LED chip when the filament, etc. There was a problem that can not be applied.

It is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a heat dissipating means for absorbing heat radiated to a light source in an internal space of a ship navigation light, And to provide a marine navigation light having a heat dissipating structure.

According to an aspect of the present invention, there is provided a lighting device comprising: a main body having an internal space in which a light source connection terminal is installed; and a light transmitting window and a cover which are assembled to an upper portion of the main body, And the heat of the light source can be dissipated to the outside.

The present invention also provides a navigation light for a ship having a heat dissipation structure, wherein the heat dissipation means comprises a heat dissipation fin block made up of a plurality of heat dissipation fins.

The heat dissipating fin block of the present invention comprises a heat absorbing part installed in the inner space through a hole formed in a bottom part of the inner space and a heat dissipating part connected to the outside of the body to dissipate the heat conducted from the heat absorbing part to the outside A navigation light for a ship having a heat dissipating structure is provided.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as claimed. .

1 to 4, the present invention includes a main body 100 having an internal space 2 in which a light source connecting terminal 1 is installed, and a light transmitting window (not shown) coupled to an upper portion of the main body 100 200 and a cover 300. The heat sink 400 is installed in the inner space 2 of the main body 100 so that the heat of the light source 3 can be dissipated to the outside .

The heat dissipating means 400 uses a heat dissipating fin block 5 having a plurality of heat dissipating fins 4.

The heat sink fin block 5 is connected to the outside of the main body 100 and a heat absorbing portion 5a provided in the internal space 2 through a hole 6 formed in a bottom portion of the internal space 2 to absorb heat, And a heat dissipation unit 5b for dissipating the heat conducted from the heater 5a to the outside.

The heat radiating fin block 5 is installed in the inner space 2 of the main body 100 and the radiating fin 4 is formed in an appropriate number corresponding to the size of the navigation light.

As another embodiment of the heat dissipating means 400, a heat pipe 7 sealing the heat medium oil may be used.

The heat pipe 7 is composed of a heat absorbing tube 7a provided along the inner space 2 of the main body 100 and a heat dissipating tube 7b connected to the outer surface of the main body 100 through a hole 8 .

As the thermal oil, oil, organic compound, volatile liquid and the like having excellent thermal conductivity are used.

In the present invention as described above, the heat dissipating means 400 for dissipating the heat radiated from the light source 3 to the outside is provided in the inner space 2 of the main body 100 on which the light source 3 is installed, So that it is possible to extend the lifetime of the light source 3 and exert the original brightness of the light source 3.
