Description

Street lamp {Street lamp}

The present invention relates to a street lamp, and more particularly, to circulate outside air into a street lamp to dissipate heat generated from the lamp, and to a street lamp for collecting rainwater introduced into the street lamp and discharging it to the outside.

In general, the light emitting diode is one of the solid state light emitting diodes, and a single color light emitting device including red (R), green (G), and blue (B), which are three primary colors of light, is implemented as well as a white light LED that can be applied to various fields. It became.

Unlike general fluorescent lamps, lighting facilities using light emitting devices have a simple lighting circuit, do not require inverter circuits and iron ballasts, and consume less power and have a lifespan of about 10 times.

Accordingly, the application field of the light emitting device is gradually increasing its application range as a next-generation lighting equipment that can replace incandescent lamps, fluorescent lamps, street lights, as well as the light emitting source for the backlight of the display in a general display device.

In the street lamp using such a light emitting device, a cover disposed on a back surface of a substrate on which a plurality of light emitting devices are attached is formed of a metal material, thereby cooling heat by emitting heat generated from the light emitting device having high brightness to the outside through the cover.

However, in the case of the metal cover, the heat dissipation efficiency is low, the internal temperature of the head portion of the street lamp LED lamp is installed, there is a disadvantage that the LED and the electronic components are damaged or the life is shortened by the heat.

In addition, when rainwater flows into the lamp, there is a problem in that a lamp is defective due to rainwater because no discharge means is provided to discharge the rainwater flown outward.

The present invention was devised to improve the above problems, and circulates the outside air in the street lamp to dissipate heat generated from the lamp, and to provide a street lamp for collecting rainwater introduced into the street lamp and discharged to the outside. have.
