Description

[0001] The present invention relates to an LED lamp for a marine module having a detachable module structure,

The present invention relates to a marine LED lamp having a removable module structure, and more particularly, to a light source module in a lamp groove formed into a disc-shaped module capable of being detachably attached to an existing housing, To a marine LED lamp having a detachable module structure to be used in various applications such as the above.

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. It is classified into long, light, and stern depending on the installation position. Normally, red light of a port light is illuminated and green light of a green light is illuminated within an irradiation angle range of 112.5 °. , White light is illuminated within an irradiation angle of 135 ° so that a safety accident at sea can be prevented in advance by identifying the course direction of the ship at night navigation.

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 general, an incandescent lamp is a typical electric component used mainly for lighting. It is composed of an incandescent lamp and a socket for fixing the incandescent lamp. In order for the incandescent lamp to emit light that emits darkness, It must be assembled into a socket that is electrically connected to an external power source.

The incandescent lamps constituting such incandescent lamps are classified into a glass ball which is filled with an inert gas such as nitrogen and argon, a filament which generates heat when an electric current flows and a coiled tungsten line which generates light when heat is increased A glass stem provided inside the glass sphere to support the lead wire and having a lead wire electrically connected to the filament, a base electrode part formed at the lower end, and a round screw-threaded screw part formed on the outer surface Base and so on.

However, the above-mentioned incandescent lamp has a short life span as compared with an LED and a large consumption of electricity, and its use tends to be limited.

Therefore, many lamps using LEDs which have less energy consumption than conventional incandescent lamps and have a long life and various lighting effects are being developed.

The LED lamp includes an LED and a PCB inside a lamp housing having a reflective layer formed on an inner side thereof so that light emitted from the LED is emitted through the lens.

In the lower part of the lamp housing, a lead-out hole for drawing electrode pins for supplying power to the PCB is formed, and an adhesive is filled in the space between the PCB and the lamp housing to fix the electrode pins and the PCB.

In the LED lamp having the above-described structure, a space for forming the reflective layer is secured in the front surface of the LED, so that the LED has to be mounted on the lower surface of the lamp housing.

1, a conventional LED lighting apparatus 10 includes an LED module including a plurality of LED elements 14 and a printed circuit board 13 for driving the LED elements 14, A heat sink 16 made of an aluminum material on the back surface of the printed circuit board 13 so as to allow heat generated from each of the LED elements 14 to be emitted to the outside, And includes a surrounding glass bulb 15.

However, since the light emitted from the LED device has a linearity, the irradiation range is considerably narrower than that of the conventional interior lamp when it is used for an interior lamp or a street lamp. In the conventional LED illumination device, since the LED module is mounted on the case so that the LED module faces downward, almost no light is transmitted to the reflector disposed around the LED module. In this manner, due to the narrow irradiation angle of the light emitted from the LED device, only a region immediately below the lighting device is excessively bright and the distribution of the luminous intensity as a whole is uneven.

In addition, in general, a lamp such as a conventional incandescent lamp or a three-wavelength lamp is used as a lamp of a signal lamp used in a ship. However, in such an illumination lamp, a light source section providing a light source has a light distribution curve of 360 degrees, A separate light collecting structure is additionally required in the housing such as a traffic light or a voyage.

In addition, the conventional signal lamp or navigation lamp has a problem in use due to a loss of function due to the breakage of a general lamp in a glove, and a sudden drop of the luminous flux with time.

Therefore, by using LED instead of the conventional incandescent lamp, it is possible to provide a general-purpose LED lamp which can be used for marine signal lamps and navigation lights that are strong against impact, prolonged life, reduce power consumption and reduce maintenance cost, Is urgently needed.
