Description

(LED underwater lights with high pressure to maintain the weatherproof and moisture-proof property)

The present invention relates to an LED underwater, and more particularly, to an LED device capable of illuminating light in all directions while allowing light emitted from an LED device to reach a long distance in water (under water) The present invention relates to an LED lamp that can remarkably improve pressure resistance and water tightness and can maintain a waterproof and moisture-proof performance even under a high water pressure.

LED light is a light emitting diode (LED) has less power consumption, has a semi-permanent life span, less time to light up, and can produce natural light because of the advantage of street light, security, tunnel, And it can affect the plants, plants and human body by using a special single wavelength which can not be realized in the existing light source. Therefore, there is a demand for replacing the existing light sources It is increasing exponentially.

For example, a fish can be classified into a light-stimulating fish species that follows light in response to light, and a non-fish species that does not follow light, such as squid, anchovy, mackerel, horse mackerel, In order to catch fishes such as sardines, it is common to use an ear bud while fishing. In the past, a metal halide lamp has been mainly used as a fish eye catcher. However, since the luminescent efficiency is low and power consumption is high and the lamp must be periodically replaced Recently, a lot of LED lights have been used.

For example, Patent Application No. 2010-129800 entitled " LED underwater lighting and glue light actively responding to changes in water pressure "has emerged. However, the above patent discloses that the structure of the glider structure is an envelope type envelope, It is not possible to use it at all for purposes other than a fishing rod used for underwater use because it is shaken by a large amount of surface area, .

In order to solve the above problems, the present applicant (inventor) has developed a patented patent No. 1400069 entitled " LED lighting device capable of omnidirectional illumination with heat, waterproof and moisture-proof structure by fluid " As a result, the problem that was not expected was revealed.

In other words, when the tongue is deeply penetrated into the sea up to 100m depth, a huge water pressure of about 10 tons is applied and the tongue keeps moving by the tide, and the vibration is applied. The upper and lower frames of the tongue are bonded with the light pipe bonding or tightening the screws. Therefore, the pressure resistance and seismic resistance against the large water pressure are poor. Therefore, the following problems occurred. First, there is a problem that a great hydraulic pressure acts at deep water depths, vibrations are applied due to continuous movement of the earpieces by tidal currents, cracks are generated in some fastening portions and close contact portions, and perfect sealing can not be ensured.

Second, the weight of the earthing light mounted on the tip of the cable is more than several kilograms. When the earthing light is dropped into the seawater and the ear is lifted up to the deck, the cable is broken at the connection portion between the cable and the earthing light. The cable is damaged and the cable and the headlight are separated from each other.
