Description

A flashing apparatus for High luminance LED, and LED beacon with the same}

The present invention relates to a marine lighter, and more particularly, by adopting a high brightness LED having a much higher brightness than a conventional bulb lamp or shell type low brightness LED, high brightness can be realized, and is generated due to high heat generation of a high brightness LED. By discharging high heat effectively and quickly, it is possible to prevent breakdown or damage caused by thermal deformation, and also, the heat dissipation structure is simple compared to the conventional one, and the compactness is designed so that the weight increase due to the heat dissipation structure is not large. It relates to equalizer using the same.

In general, various types of route markers are installed and operated in the sea near the coast or harbor to safely guide the ship's route and identify the hazards at sea.

The light register mounted on the sea buoy is to help the safe operation of the ship by providing the location information by using the light emitted from the light source, and the brightness should be above a certain level, and it should be able to be driven with low power and light in weight.

In the case of the conventional bulb-type lighter, there is a problem that not only the weight is large but the replacement time of the bulb is short and the power consumption is severe. In addition, the 5mm shell-type low-brightness LED lamp has the advantage of long life and low power. However, in recent years, the demand for high-brightness lamps incorporating high-brightness LEDs is increasing due to the increase in the backlight of the sea.

Therefore, recently, a light emitter adopting a high brightness power LED having a power consumption of 1W or more as a light source has emerged.

Regarding such an identifier, various kinds and standards have already been known and patented or registered in Korea and abroad, and FIGS. 7 to 9 are front cross-sectional views illustrating some of the structure of the identifier.

FIG. 7 relates to a light register designed to be able to arbitrarily adjust the quantity of light sources as disclosed in Korean Patent No. 0920757, "Light source module used in the light register, and the light emitter having the same."

FIG. 8 discloses a light emitting device having a central LED rotating device. The beam is emitted from the upper lamp body by automatically maintaining the upper lamp in a vertical state even when the buoy is inclined according to the sea weather conditions. It relates to an equalizer that ensures that the angle of up and down is always horizontal.

9 is disclosed in Applicant's Patent No. 0897919, "High Brightness LED Declarator," which uses a high brightness power LED to form a light emitting means in a single layer, thereby simplifying a structure to reduce power consumption and dissipating high heat generated from a high brightness power LED. And an equalizer to be treated using a heat pipe.

As described above, as the back light increases due to the rapid urbanization of facilities near ports and coasts, the brightness required for the light register is also gradually increasing, and high brightness power LED lamps satisfy these requirements.

By the way, in the case of such a high-brightness power LED, the brightness is very high compared to the conventional shell-type LED, but the power consumption is relatively very high, there is a problem that heat generation is severe accordingly.

Therefore, the heat radiation problem must be considered when employing a high brightness power LED to increase the brightness of the illuminator. Otherwise, the product cannot run stably due to the heat generated by the high-brightness power LED, and eventually, the related parts may fail or break.

In the case of the registered patent disclosed in FIG. 8, the cooling structure of the LED heating element is not disclosed at all, and in the case of the registered patent disclosed in FIG. 7, a light source module including a heat radiating fin to which an LED light emitting member and a laminated condenser lens are attached is provided. It is arranged by plural in the circumferential direction of the upper body, the heat dissipation effect is not satisfactory, and there is a problem of weight increase due to the increase in the number of installation of the heat radiation fin of the aluminum metal material.

In the case of the registered patent of FIG. 9, a heat radiating fin made of a relatively light aluminum structure and a flat heat pipe structure connected to the heat radiating fin are adopted to radiate the high-brightness power LED. Installing is a challenge.

Therefore, by applying a high brightness power LED lamp to replace the conventional bulb lamp or low power shell type LED lamp, the brightness is increased, but the heat dissipation effect of the high brightness power LED made of high brightness power LED is high while the power consumption is high, There is a need to develop an isochronizer with a structure that does not increase weight.

Patent No. 0920757 "Light source module used in the lamp, and the lamp having the same" Registered Patent No. 0798728 "Central LED Lighting Machine Rotator" Registered Patent No. 0897919 "High Brightness LED Lamp" Registered Patent No. 0586862 "LED Register"

Since the heat dissipation is achieved by using the air circulation structure leading to the sink, the heat dissipation is quick and efficient, and there is an advantage of preventing an increase in weight due to an increase in the heat sink.
