Abstract
Description
More particularly, the present invention relates to a safety LED (Light Emitting Diode) which uses an LED as a light source for heat dissipation and explosion proof. The heat dissipation area is widened to rapidly dissipate heat, And an LED explosion-proof which prevents lifting of the ballast housing due to vibration or the like.
Generally, an explosion-proof structure is a structure of a container made such that a gas intruding into a container of an electric device does not affect an external gas even if an explosion is caused by a flame or heat of an electric circuit therein.
Meanwhile, the International Electrotechnical Commission (IEC) and the National Fire Protection Association (NFPA) classify hazardous places into approximately zero, one, and two locations according to the hazardous conditions. In particular, the zero type and type 1 places are always exposed to fire, explosion, and heat. Therefore, electric appliances are required to have an explosion-proof structure.
In other words, the use of explosion-proof equipment is legally required to prevent explosive gas from surrounding electrical equipment used in dangerous places, such as factories handling hazardous materials such as gas or chemical substances, from becoming an ignition source.
Accordingly, the pressure-proof explosion-proof structure must have mechanical strength to withstand the explosion pressure of the container, and the flame or hot gas generated by the explosion inside should not ignite the external gas through the joint portion of the container, The temperature should not reach the ignition temperature of the external gas.
A general explosion-proof lamp is a structure that can withstand external shocks by introducing air or an inert gas so that even if an explosive gas penetrates inside the device, it does not burn. Such explosion-proof lamps generally use incandescent lamps, fluorescent lamps, and three-wavelength lamps as light sources, which have a problem of high power consumption and short life span.
In addition, if the light source and the stabilizer are not properly heat-dissipated, the explosion-proof lamp has a problem that the lifetime is shortened due to overheating and the situation is very dangerous.
Therefore, explosion-proofing using a light emitting diode (LED) as a light source has been proposed.
FIG. 1 is an exploded perspective view showing a conventional LED explosion-proof, etc., and FIG. 2 is an assembled perspective view showing a conventional LED explosion-proof.
As shown in FIGS. 1 and 2, a conventional LED explosion-proof lamp includes an
A radiating fin F is radially formed on the upper surface of the
Conventional LED explosion-proof lamps have almost no risk of sparking of the lamp due to heat by adopting the LED lamp, and the casing can be made lighter and smaller.
Although it is known that these LEDs have a semi-permanent lifetime, it is important to quickly and efficiently emit heat emitted from the LEDs when the LEDs are lit so that the PCBs in which the LEDs and the LEDs are arranged are not exposed to high temperatures.
However, in the conventional LED explosion-proof lamp, a heat sink is provided on the outer edge of the casing to dissipate heat, but a stabilizer is provided adjacent to the light source to deteriorate heat dissipation and safety, and a
In addition, there is a problem in that the coupling portion of each constituent element such as the connecting portion of the power source driving unit casing is loosened due to vibration, and the sealed state is not maintained.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to solve the above problems by providing an LED explosion-proof lamp .
According to an aspect of the present invention, there is provided a liquid crystal display comprising: a main body having a radiating fin formed on an outer surface thereof and having an inner space portion opened at one side thereof; an LED module embedded in the inner space portion; An annular cover for supporting the light emitting portion; A mounting box provided with a mount and attached to the ceiling; A power supply pipe connected to the light emitting unit and the mounting box by screw connection, the electric supply line being connected to the inside of the mounting unit; And a ballast housing connected to a side of the mounting box and having an inner space formed by square pillars for receiving the ballast, and a radiating fin formed on the upper and lower surfaces of the outer casing in a lateral or longitudinal direction.
In the present invention, the ballast housing may include a cylindrical inlet having a thread formed on an inner circumferential surface thereof, and a ballast housing cap having a thread formed on the outer circumferential surface thereof and coupled to the cylindrical inlet and having a plurality of protrusions formed at radially- desirable.
In the present invention, the power supply pipe includes a penetration penetration hole formed with a through hole through which each electric wire passes, and a metal ring is additionally formed in the power supply pipe for press-fitting the moisture penetration barrier.
In addition, the ballast housing is provided with a protrusion, and when the ballast housing is connected to the mounting box, a screw is fastened to the connection tube of the mounting box at the protrusion to prevent the ballast housing from loosening.
The present invention can reduce size and weight by using an LED lamp, reduce power consumption, and have a heat radiating fin formed outside the ballast housing. Therefore, the heat dissipating area is increased to provide better heat dissipation, And the safety can be improved.
In addition, the stabilizer is stably installed in the square-column type ballast housing, and after the ballast housing is coupled, the screw can be further tightened to the protrusion to prevent the ballast housing from loosening due to vibration.
