Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a double-

The present invention relates to an LED lamp having a double waterproof structure, and is designed to protect a LED module and a power module (SMPS), which are weak parts of LED lighting, from water, Packing is sealed and the waterproof packing of circular ring type having a cross section with external thread structure is pressed by the joint part of external thread structure to realize waterproof function, .

Currently, various kinds of illumination lamps using LED elements that are significantly lower in power consumption than the other light sources in the residential / industrial area are being provided.

However, the conventional LED illumination lamp is not easy to implement the waterproof function, and thus, there is a problem that it is used in a limited part of indoor or waterproof function.

In the case of such LED lighting, it is installed in a building such as a home or an office, an outdoor facility / an industrial use, an agricultural use, and is used according to its use.

In this case, water, moisture, or other foreign matter penetrates into the interior of the interior of the interior of the interior of the interior of the interior of the interior of the interior of the interior.

In order to solve such a problem, conventionally, a side-cap is coupled to a frame-cover combination while a water-tight packing in the form of a ring is used therebetween.

Particularly, the frame and the cover constituting the frame-cover combination are each half-divided into a hemispherical shape so that they are fastened with each other. In this structure, a screw is used while fastening the ring- There is a problem that the waterproofing performance can not be guaranteed due to penetration of moisture or water into the threaded joint portion through a gap in the connection portion.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to provide an external cover for protecting an LED PKG and an electric power module (SMPS) vulnerable to water and having a cylindrical pipe shape, It has a closed cover with side cover part and a circular cross-section waterproof packing in the form of a circular ring. It is installed inside the LED lighting lamp to completely block the contact between the LED module and the electric power supply part. A LED lighting fixture having a waterproof function for preventing damage caused by a lamp is provided.

And the power module (SMPS) part inserted inside the LED lighting is inserted into the inside of the aluminum frame and inserted into the protective case of the power module having the electric insulation and the waterproof function.

When the ring member is used in the form of a ring by a conventional waterproof member, the side cap is in contact with the surface of the ring member simply by being in contact with the surface of the ring member, There is a problem that it is difficult to ensure airtightness in the waterproof member due to a difference in the amount of pressing and the amount of pressing.

In order to ensure a sufficient amount of waterproofing of the waterproofing member and to ensure airtightness, the waterproofing member is screwed into the circular ring-shaped watertight packing having a "?" And a waterproof LED lighting lamp which can ensure reliability and waterproof safety.

The waterproof structure according to the present invention is characterized in that the waterproof structure according to the present invention includes a first sealing structure by an outer cylindrical cover and a watertight packing, and a second sealing structure for protecting a power module (SMPS) inserted into the aluminum frame structure inserted inside the cylindrical cover It is another object of the present invention to provide an LED lighting lamp having a double waterproof performance, which is capable of maintaining a high level of waterproof performance.

The present invention is configured as follows to achieve the above object.

A light-transmitting frame is mounted on both sides of a cylindrical pipe-type light-transmissive case, a light-transmitting case is formed in a pipe-like structure without a gap in an external assembly structure, and a power module And a secondary protection case is formed on the side surface of the cylindrical light-transmissive case, and the waterproof packing is coupled to the end of the side surface of the cylindrical light-transmissive case so that the screw of the side cap and the nut- And the water-tight packing in the form of a circular ring is pressed and pressed to have air-tightness evenly.

The watertight packing used as the waterproof member according to the present invention is formed by a rubber material having elasticity or a synthetic plastic material of an elastomer series so that a packing mounting groove having a depth between the light transmitting case and the side cap engaging portion of the cylindrical pipe is formed And a watertight packing in the shape of a circular ring having a " C " -shaped cross section in the formed packing groove is inserted into the pipe-shaped side portion when the watertight packing is coupled with the translucent case.

In addition, the waterproof packing structure of the circular ring type having a " true " cross-section between the light-permeable case and the side cap has a primary waterproof structure for pressing the water- And a secondary case having a secondary waterproofing structure for protecting a power supply part formed inside the heat radiation frame inserted inside the light transmission case, and having a double waterproof structure.

The illumination lamp having a double waterproof structure and a completely waterproof performance according to the present invention includes a light pipe case cover in the form of a cylindrical pipe surrounding the LED module and the heat radiation frame embedded in the heat dissipation frame, And a light transmission case-coupling nut for pressing the water-tight packing in the form of a circular ring having a "

This is because when the O-ring type ring member is used as a conventional waterproof member, both ends of the heat-radiating frame-cover combination are in contact with the ring member surface in such a manner that they are simply in contact with each other and tightened with screw bolts. In order to solve the problem that it is difficult to ensure the airtightness by the waterproof member to the complete waterproof due to the tilting phenomenon,

It is a cylindrical pipe type light-emitting case that eliminates the external coupling structure and is a structure that can not infiltrate with water and moisture at the origin. It is a circular ring type water-tight packing having a "?" The watertight packing in the form of a circular ring having a cross-sectional shape with a casing-engaging nut is pressed against the entire joint surface of the cylindrical type, thereby greatly improving the airtightness, thereby ensuring watertight reliability and safety of the product.

And a waterproof packing of circular ring shape having a cross section of " C " to secure the first waterproof airtightness, and a case which protects the power supply part while coupling the power supply part inside the heat radiation frame coupled to the inside of the light transmission case, By adopting a sealed case to construct a double waterproof structure, it is possible to maintain a waterproof performance with higher perfection.
