Description

Street lamp head {Street lamp head}

The present invention relates to a street lamp head, and more particularly, to a street lamp head that can quickly release the heat generated from the lamp unit installed in the street lamp.

In general, the light bulbs used in street lamps use mercury bulbs as much as sodium bulbs. Sodium and mercury bulbs have advantages and disadvantages, but they are used for proper use. The brightness of the low, compared with the power consumption is a lot of energy efficiency is low.

Therefore, recently, streetlights using light emitting diodes (LEDs) have been developed. Conventional streetlights using light-emitting diodes have significantly lower power consumption than conventional streetlights using conventional sodium or mercury bulbs, and have higher brightness than traditional streetlights. As it can be extended several times, management costs can be greatly reduced, and replacement with existing streetlights is also increasing.

As such, the light emitting diodes used in streetlights have advantages of high brightness, low power consumption, and long lifespans compared to conventional light bulbs, and thus their use is increasing not only in streetlights but also in various fields such as indoor lighting, decorative lighting, and vehicle lighting.

However, since a single light emitting diode alone cannot satisfy the high brightness required by a street light, a large number of light emitting diodes are usually connected to each other to form a module, and the modules thus configured are connected in series or in parallel. High brightness by configuring a single lamp.

As long as the light emitting diode lighting connected with a module consisting of a plurality of light emitting diodes is turned on for a long time, the light emitting diodes having low heat resistance are damaged by heat, so that a failure occurs frequently. Because a cooling structure must be provided to prevent failure due to overheating of the lamp by dissipating the heat of the diode, each company that manufactures a streetlight using the light emitting diode emits heat of the light emitting diode using a unique technology.

In order to solve the problems of the prior art as described above, Korean Patent No. 10-1035944 discloses a streetlight mechanism having a natural convection heat dissipation function.

Protrudes, and a bottom surface of the protrusion is formed on an upper side of the upper case. It is is the cover plate installed to be spaced apart from the upper surface of the upper case so as to cover the upper side of the air circulation hole.

However, the street light fixture having the natural convection heat dissipation function has a problem that the size and weight of the overall street light fixture increases because the upper and lower widths of the heat sink are thick, and the upper case is closed and the air distribution hole is formed in a part of the lower case. There is a problem that the efficiency is low because the amount of air passing through the heat sink is not substantially large.

The present invention is to solve the conventional problems as described above, by heat dissipating heat generated in the light emitting diode more quickly and with high efficiency to improve the efficiency and life of the light emitting diode, mounting portion mounted to the light emitting diode module And to provide a street light head that can reduce the volume and weight by integrally forming a heat dissipation unit for dissipating heat generated from the light emitting diode.

The first heat dissipation unit is characterized in that it is formed to have a honeycomb structure.

A space portion is formed between the mounting portion and the first heat dissipation portion, and the second heat dissipation portion extends from the first heat dissipation portion toward the mounting portion so as to contact the upper and lower surfaces of the mounting portion via the space portion; And a first contact rib and a second contact rib.

The first contact ribs and the second contact ribs are characterized in that a plurality of air passage holes are formed so that air can pass through the position corresponding to each other in the vertical direction.

According to the street lamp head according to the present invention, the heat generated from the light emitting diodes can be released more quickly and with high efficiency, thereby improving the efficiency and life of the light emitting diodes, and the heat generated from the mounting portion and the light emitting diodes on which the light emitting diode modules are mounted. Since the first heat dissipation unit for dissipating the heat dissipation unit is integrally formed and does not require a separate heat dissipation plate, it is possible to reduce the volume and weight of the street light head.
