Description

[0001] Square heat dissipation heat sink for Floodlight [

More particularly, the present invention relates to a quadrangular heat sink for a light emitting diode (LED) light source, and more particularly, to a quadrangular heat sink for a LED light transmitter which is capable of increasing the efficiency of heat conduction to a plurality of heat radiating fins through a heat releasing grease applied to a base portion and a base portion, So that heat dissipation of heat in the heat dissipation fin of the heat dissipation fin is increased.

Generally, a heat sink refers to a metal plate that discharges the heat inside the product to the outside using heat conduction phenomenon such as radiation or convection.

The higher the thermal conductivity of the heat sink, the more effective it is to use the copper plate. However, since the price of the copper plate is very high, the aluminum material is often used. Also, since the larger the contact area with the external space is, the higher the heat dissipation efficiency, the larger the area of the heat sink is, the better. Thus, the shape of the heat sink is formed to include irregularities.

And general lighting devices such as fluorescent lamps and incandescent lamps generate heat and light together, but in the case of LEDs, the light is generated in the forward direction, but the heat is generated in the backward direction and directed into the module.

If the heat is not discharged to the outside, the module remains inside the module. This causes breakage and deformation of parts such as an LED chip and a PCB, thereby reducing the lifetime of the LED product.

Therefore, the heat sink is the biggest factor that leads to the short life of the LED, and the role of the heat sink is to allow the heat inside the product to be quickly discharged to the outside.

A radiating and fixing unit for fixing a heat sink to a base plate formed in the form of a plate-like container provided with an internal space, such as Korean Registered Patent No. 10-1340411 (registered on Dec. 05, 2013) related to the heat sink, The tension spring formed of a metal body solidified from a liquid phase to a solid phase so as to be fixed to the same body is inserted into the lower side of the heat sink to enhance the heat radiation efficiency. However, the heat sink is inserted only under the plurality of heat sinks, Accordingly, there is a disadvantage in that heat is discharged to the outside in such a manner that the fixed supporting point is concentrated on the lower side of the heat sink, and the heat of the LED is intensively conducted to the lower side of the heat sink, and only through the tension spring on the lower side of the heat sink, There is a problem in that it can not be firmly fixed.

Accordingly, the heat of the LED is entirely transmitted to the upper and lower sides of the heat sink, thereby maximizing the efficiency of heat exhaust to the outside, and the upper and lower sides of the heat sink are firmly fixed to the base plate, And to search for ways to do so.

More specifically, the second fixing plate 330 is seated in the second receiving recess 212 formed at both ends of the lower side of the plurality of the heat-radiating fins 210, so that the second fixing member 340 is passed through in the longitudinal direction And a screw hole 331 is formed on the inner side where the both sides are bent and the upper side is opened.

The second fixing plate 330 is seated on the upper side of the second supporting member 230 coupled to the second receiving groove 212 of the plurality of radiating fins 210, The upper end of the second support member 230 is coupled to the upper side of the heat dissipation base 110 through a screw hole 231 formed in the plate 330 and the second support member 230,

The second fixing member 340 penetrates the second fixing plate 330 in the longitudinal direction and the lower end of the second fixing member 340 is coupled to the upper side of the heat dissipating base 110. Heat generated in the heat emitting body is transmitted to the heat dissipating base 110 And the heat of the transferred heat is transferred to the lower side of the plurality of radiating fins 210 through the second fixing member 340 so that heat radiation is increased in the plurality of radiating fins 210 .

As a result, heat is transferred to the plurality of radiating fins through the radiating grease applied to the base portion and the base portion of the heat generating body, thereby increasing the heat radiation of the plurality of radiating fins.

The plurality of radiating fins are firmly coupled to the upper side of the base portion through the plurality of supporting members and the plurality of fixing members, thereby increasing the efficiency with which the heat of the heating elements is transferred to the plurality of radiating fins.

Further, since the lower ends of the plurality of fixing members formed of a metal are coupled to the base portion, efficiency of heat transferring from the heat generating element to the plurality of radiating fins is increased, so that heat radiation from the plurality of radiating fins is increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
