Description

{LED Navigation light for vessels}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to navigation light for a ship that allows the user to know the traveling direction of a ship while at night, etc., and more particularly, to an LED navigation light capable of achieving uniform horizontal light distribution using an LED.

In general, a navigation light is installed to indicate the existence and direction of a ship during night voyage or in restricted visibility due to fog or smoke. The navigation light is classified into 1, 2 Depending on the installation position, it is classified as long, light and stern.

Conventional marine navigation lights use incandescent lamps such as filament lamps or halogen lamps. When a ship is operated, it can not be repaired or replaced if the bulb life is shortened or a fault occurs due to disconnection of the filament inside the bulb. .

However, existing marine navigation lights not only exhibit very high luminance according to the international navigation standards, but also have a problem that the base supporting the light source is damaged due to high heat because the light is illuminated for a long time, or the life of the light source itself is reduced.

In the conventional marine navigation lights, 95% of the energy generated when the current flows through the filament is discharged as heat and only about 5% is converted into light. As a result, incandescent lamps or halogen bulbs having a very low luminous efficiency are used as light sources. In addition, since the lifetime of the filament is shortened to 1/2 to 1/5 level due to the hull vibration generated by the engine driving during the operation of the ship, the durability is remarkably decreased, There was a problem.

In order to overcome such a problem, it is possible to greatly reduce power consumption compared with existing marine navigation lights, and to provide a high-output high-brightness LED capable of significantly extending the service life by exhibiting characteristics of hull vibration generated when the engine of a ship is driven There has been proposed an LED navigation light for use as a light source.

As shown in FIG. 1, a conventional marine LED navigation light uses a plurality of multi-chip LED packages 2, which are constructed by integrating a high-output high-brightness LED chip, as a light source. As shown in FIGS. 2 to 4, the multi-chip LED package 2 includes a lower body 3 having a plurality of lead frames 4 on both sides thereof and a heat sink 5 at the center thereof A plurality of LED chips 6 individually connected to the respective lead frames 4 are mounted on the upper surface of the heat sink 5 of the lower body 3, And a lens 8 is attached to an upper portion of the light transmitting hole 7a of the upper body 7. The upper body 7 has a through hole 7a,

However, since the conventional marine LED navigation light configured to illuminate all of the plurality of LED chips 6 in each multi-chip LED package 2 simultaneously, If the heat generated when all of the plurality of LED chips 6 are simultaneously turned on is not sufficiently radiated, there is a problem that the luminous efficiency is drastically reduced or the life span is remarkably shortened.

Therefore, in order to commercialize an LED navigation light for a ship, there is a desperate need for measures to completely solve the problem of reduction in efficiency and life span due to the heat generation of the LED chip.

In addition, due to the structure in which a plurality of LED modules are arranged in a luminaire of an LED navigation light for ships, it is difficult to realize uniform horizontal and vertical light distribution.
