Description

Tunnel light which radiates internal heat naturally {TUNNEL LAMP FOR NATURAL EMITTING INTERNEL HEAT}

The present invention relates to a tunnel lamp for spontaneously radiating internal heat, and more particularly, to a tunnel lamp for spontaneously radiating internal heat capable of spontaneously radiating high heat inside the tunnel lamp according to the lighting of the tunnel lamp.

As a tunnel lamp 1 for radiating internal heat, which is widely used in the related art, it is disclosed in Korean Patent Utility Model Publication No. 20-0244565 (registration date; August 17, 2001).

Tunnel lamp 1 for radiating the internal heat disclosed in the registration number 20-0244565 of the Korea Utility Model Publication No. 1, the upper case 11 and the lower case 12 as shown in Figs. In a closed tunnel, which is completely engaged to achieve the effect of waterproofing and dustproofing, vent holes 2 are formed on the outer circumferential surface of the lower case 12 so as to face each other, and vent holes 21 are installed to open and close according to temperature changes. An overheat prevention device (2) capable of lowering the temperature inside the tunnel lamp (1) through the flow of external air into the inner space formed by the upper case (11) and the lower case (12) was provided.

The overheat prevention device 2 is connected to the air vent cover 21 for sealing the vent hole 3 and the arm 211 of the plate-shaped body formed in the vent cover 21, the arm 211 and the link 24 And a solenoid 22 operated by an automatic return type overheat sensor s and a restoring spring 23 installed on the other side of the solenoid 22 to return the arm 211 to its original position.

Tunnel lamp (1) for radiating the internal heat of the prior art configured as described above is to seal the vent hole (3) formed opposite to each other on the outer peripheral surface of the lower case 12 of the tunnel lamp (1) as shown in Figs. When the solenoid 22 is operated by the overheat sensor s installed inside the vent cover 21 is white paper coupled to the lower case 12, the vent cover 21 is opened to open the hot air inside the tunnel lamp 1. Is convection easily through the vent (3) is configured to lower the temperature inside the tunnel lamp (1).

The opening of the vent cover 21 of the overheat prevention device 2 is such that the automatic return type overheat sensor s on one side of the tunnel lamp 1 senses the overheating of the internal temperature of the tunnel lamp 1 and the overheat sensor ( When s) is energized, the solenoid 22 is operated and the vent cover 21 is opened by operating the arm 211 of the vent cover 21 through the link 24 through the piston of the solenoid 22.

In addition, when the internal temperature of the tunnel lamp 1 is lowered to an appropriate temperature, the solenoid 22 does not operate as the automatic return type overheat sensor s is turned off so that the restoring force of the restoring spring 23 is reduced. Therefore, the vent hole 3 is closed by operating the arm 211 of the vent cover 21.

By the way, the conventional tunnel function (1) for radiating the internal heat is configured to open the vent cover (21) even when the internal temperature of the tunnel lamp (1) in the rainy season is high, so the vent cover ( When water 21 penetrates into the tunnel at the time of opening 21, the tunnel light 1 penetrates into the tunnel and there is a problem of deteriorating the characteristics of the electric parts of the tunnel light 1 due to a short circuit. There is a problem that the lamp does not turn on due to deterioration of the lamp, and there is a risk of a fire occurring due to deterioration of the characteristics of the electric parts, and the solenoid 22, the link 24, the arm 211 and the vent cover. When (21) was rusted or damaged, there were also various problems such as a very difficult part replacement.
