Description

LED Explosion Proof Lighting, etc. {LED Explosion Proof Lighting}

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 LED lamp 10 in which LEDs 11 are arranged on a printed circuit board (PCB) 13, And a power supply driving unit 20 for controlling and supplying power to the LED lamp 10. The first casing 30 includes a main body 31 formed with a lamp mounting portion for performing heat dissipation of the LED, A second casing 40 that dissipates heat from the power source driving unit 20 and a second casing 40 that is spaced apart from the main body unit 31 of the first casing and that also serves as a wire passage C (P) in the form of a hollow tube, and the main body portion (31) of the first casing and the second casing (40) are connected by the connecting post (P).

A radiating fin F is radially formed on the upper surface of the main body 31 of the first casing 30. The first casing 30 includes a glass cover 32 which is air- A protective net 33 is fixed to the main body 31 to protect the cover 32. [

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 protection net 33 for protecting the glass cover 32 The light irradiation efficiency is lowered. In the case where a defect occurs, the casing of the power source driving unit 20 is detached and it is difficult to replace and repair the light source.

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.
