Description

{LED tunnel lamp}

The present invention relates to an LED tunnel having improved heat radiation efficiency, and more particularly, to an LED tunnel having an improved heat dissipation efficiency and having a module mounting portion and an electric component chamber separately for easy maintenance.

In addition, the present invention relates to an LED tunnel and the like, which can separate and manage the heat generated from the LED module and the electrical component by separately configuring the space in which the LED module and the electrical component are installed, thereby improving heat dissipation efficiency.

In addition, the present invention relates to an LED tunnel, which is formed by connecting a plurality of LED modules in parallel, so that illumination efficiency can be improved by lighting the LEDs of the remaining LED modules even when an abnormality occurs in one of the LED modules.

In addition, in the present invention, the LED module is coated with a transparent material so as not to be contaminated by moisture or dust from the outside, and a cover can be provided in the electric room for opening and closing to facilitate maintenance, The present invention relates to an LED tunnel having improved heat dissipation efficiency by reducing the vibration of the LED module installed in the module mounting part by reducing the vibration of the electric room fixed to the wall formed by extending from the electric room.

Fluorescent lamps and incandescent lamps are often used as lamps, but fluorescent lamps use less fluorescent light than incandescent lamps, so they are mostly used for lighting purposes, and most offices use these fluorescent lamps. However, since a fluorescent lamp has a low illuminance and low energy efficiency, recently, an LED illumination using a light emitting diode (hereinafter referred to as "LED") is widely used as an illumination lamp having relatively higher illuminance and lower power consumption than these.

The LED illumination typically includes an LED substrate on which a plurality of LEDs are mounted and a circuit pattern is formed on the LED to supply power to the LED, and a housing for supporting the LED substrate. The power supply includes a power supply for supplying power to the LED. [0003] In such an LED illumination, a lot of heat is generated when the LED is emitted, and various techniques for discharging such heat have been developed. Patent literatures 1 and 2 are technologies related to such LED illumination.

Patent Document 1 is an improvement of the heat dissipation structure. In order to improve the heat dissipation effect, Patent Document 1 proposes an outer heat dissipation tube 100 in which a plurality of heat dissipation vanes 100w radially protrude from the outer surface, and a plurality of heat dissipation vanes 200w are formed on the inner surface of the inner tube 200 to allow heat dissipation to the outside. This is an air-cooling system in which the heat radiation is made only by the heat dissipation vane.

Patent Document 2 discloses an LED illumination lamp which can easily be replaced with a ballast, and includes a frame having an upper plate attached to the ceiling and a side plate formed around the upper plate, the frame having a plurality of mounting holes formed on the upper plate; A substrate mounted on a lower surface of the upper plate of the frame to close the mounting hole and having a plurality of LEDs mounted on a lower surface thereof; And a stabilizer mounted on the upper surface of the substrate and inserted into the mounting hole. The LED illumination of the patent document 2 has an advantage that the ballast can be easily replaced, but it has a disadvantage that the entirety of the ballast must be replaced when a failure occurs due to a single LED panel.

In other words, in the conventional LED lighting apparatus, since the electrical components including the LED module, the converter for supplying electricity to the LED, and the ballast are installed in one space, the heat generated from the LED module and the heat generated from the electrical component are stored in one space There is a drawback that the heat dissipation efficiency is lowered.

In addition, since the LI module and the electrical parts are installed in one space, it is difficult to replace only the damaged parts when one of the parts is damaged. Therefore, there is a problem that unnecessary materials are wasted.

In addition, when the LED light is installed in a place such as a tunnel, a cover made of a transparent material is installed to protect the LED from foreign matter such as dust inside the tunnel. This cover is generated by a vehicle passing through the inside of the tunnel There is a problem in that a vehicle accident is caused by being separated from the main body due to the vibration to fall.
