Abstract
Description
The present invention relates to a pressure-resistant explosion-proof LED lamp, and more particularly, to an explosion-proof LED lamp having a structure in which an illuminating body located inside is sealed without being exposed to the outside, It is about LED light.
In general, explosive gases and explosive atmospheres due to vapors or dust are formed, and factories handling various flammable materials are areas of constant risk. These hazardous areas are classified into 0, 1, and 2 hazardous areas according to the hazardous conditions. Among these hazardous areas, 0 and 1 are always exposed to fire, explosion and heat. .
The electric apparatus and the lighting apparatus used in the place where the explosion danger atmosphere is formed are designed to prevent the spark generated by the electrical coupling from being released to the outside and to prevent the gas, Structure.
For example, an explosive gas can penetrate into a small gap caused by expansion and contraction caused by blinking of the lighting apparatus, and it is difficult to obtain explosion-proof effect even if the apparatus is closed. Therefore, in the prior art, the explosion-proof lamp uses an inert gas introduced therein so as not to be ignited even when an explosive gas is infiltrated into the explosive gas. Generally, such explosion-proof lamps use incandescent lamps, fluorescent lamps, There is a problem that the size is large and power consumption is large.
In particular, when a discharge lamp such as a fluorescent lamp is used as a light source, a ballast is used to control an overcurrent, which is bulky, consumes a lot of power, and is exposed to an unstable state in a place where vibration is high.
In addition, when the light source and the stabilizer are not properly heat-dissipated, such an explosion-proof lamp has a problem that it can shorten its life due to overheating and cause a very dangerous situation. Therefore, such an explosion-proof lamp usually has a lamp having a glass bulb such as a high-pressure mercury lamp or a high-pressure sodium lamp, or a metal halide lamp, and has a pressure-resistant casing for preventing explosion of the lamp from secondary explosion in the event of spark due to overheating do.
The pressure-resistant casing has an internal pressure that resists pressure when an explosion occurs inside due to an electrical defect therein, and air tightness is required which is not likely to be ignited by external explosive gas through a joint surface, an opening or the like. A casing such as an explosion-proof casing has a structure in which a glass globe or a tempered glass is tightly bonded to a casing main body made of a metal and a protective net is formed outside the glass globe or tempered glass to protect it from an external impact.
In addition, since the lamp is formed in a form having a glass bulb, it is necessary to secure a sufficient inner space for the glass globe or the tempered glass to accommodate the glass bulb and to have an internal pressure against the breaking force at the time of explosion of the glass bulb. The entire casing including the tempered glass is thick and the explosion-proof structure is large in size.
On the other hand, there is disclosed an explosion-proof lamp using a LED as a light source, which is less likely to generate sparks due to heat, as disclosed in Korean Patent Registration No. 10-0910539, "LED explosion-proof lamp" Shinan Bulletin No. 20-0459504 "LED light source module for explosion-proof device" has a complicated structure and can not support the heat dissipation performance, resulting in lowered illuminance and short life span.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a new type of lighting system in which an internal lighting body is sealed without being exposed to the outside, Resistant explosion-proof LED illumination lamp of the present invention.
In particular, a new type of epoxy resin coating is applied on the outer circumferential surface of a glove made of PC to prevent static electricity by epoxy resin to prevent explosion which may be caused by static electricity outside the lamp And to provide an explosion-proof explosion-proof illuminating lamp.
According to an aspect of the present invention, there is provided a lighting apparatus comprising: a rectangular illumination body having an LED inside and a side cover on both sides; A groove (30) formed in a cylindrical shape and having the illumination body (20) installed therein, for emitting light of the LED of the illumination body (20) to the outside; A side cover (40) hermetically joined to a part of an outer circumferential surface of both ends of the grove (30); A

As described above, according to the explosion-proof LED illumination lamp according to the present invention, the lighting body disposed inside is hermetically sealed without being exposed to the outside, so that even when the explosion occurs in the lighting body, the flame does not propagate to the outside.
In particular, by applying a conductive epoxy paint in the longitudinal direction on the outer circumferential surface of the groove, it is possible to prevent static electricity by the epoxy resin and to prevent an explosion which may be caused by sparks due to static electricity outside the illumination.
