The present invention relates to a manufacturing method and a manufacturing apparatus for a radiator for a lamp, a radiator for a lamp manufactured by the manufacturing method and a manufacturing apparatus, and more specifically, it is easy to manufacture and improves productivity while improving heat radiation performance. It relates to a manufacturing method and a manufacturing apparatus for a radiator for a lamp to increase the service life of the lamp, and to a radiator for a lamp manufactured by the manufacturing method and the manufacturing apparatus.

In general, LEDs (Light Emitting Diodes) are used to produce injected minority carriers (electrons or holes) using a pn junction structure of semiconductors and emit light by recombination thereof, and have been widely used in various industrial fields in recent years. .

In particular, high-brightness LED lamps are semi-permanent and have very low power consumption, so they are replacing various types of lamps including conventional fluorescent lamps, incandescent lamps, sodium lamps, and mercury lamps.

That is, as various harmful substances are included through the LED lamp and the existing lamp having a short life is replaced, an effect of reducing environmental pollution is obtained, and an energy saving effect is also obtained through low power consumption.

However, the high-brightness LED used for lighting as described above has a problem in that when the high-temperature heat generated during driving of the LED is not properly radiated, the amount of light is reduced and the lamp life is shortened.

Accordingly, various types of radiators are applied to the high-brightness LED lamps. Since these LED lamps can be installed in various forms according to the installation environment, the radiators must also be guaranteed a certain heat dissipation performance regardless of the installation state.

In addition, the LED lamp including the radiator of the LED lamp should be able to freely implement the shape of the lighting device in its design and production.

First, referring to FIG. 1A, the LED light source 20 is seated on the substrate 30 on which the circuit is printed, and the substrate 30 is seated in close contact with the radiator 10.

Here, the radiator 10 has a heat radiation block 40 of a certain thickness that is seated in a state in which the substrate 30 is in close contact, and a plurality of heat radiation fins branching and extending in an orthogonal direction from one surface of the heat radiation block 40 It consists of a configuration comprising 50.

The heat dissipation block 40 constituting the radiator 10 and the plurality of heat dissipation fins 50 are applied to those made of aluminum having excellent thermal conductivity. At this time, the heat dissipation block 40 and the plurality of heat dissipation fins 50 are It is also manufactured to be integrally formed by die casting, but in this case, there is a problem in that the production cost is increased according to the manufacturing of the mold.

In addition, since only a single shape radiator 10 can be manufactured by a pre-made mold, it is impossible to deform the shape and length of the heat dissipation fin 50 so as to correspond to the shape of the lamp, so that it cannot be applied to various lamps. There is also a disadvantage that the shape of the lighting device cannot be freely implemented in design and production.

On the other hand, in order to solve this problem, as shown in Figure 1b, after manufacturing the heat dissipation block 40 and heat dissipation fins 50 separately, the structure of the heat dissipation block 40 and heat dissipation fins 50 combined A radiator 10 is provided.

That is, referring to FIG. 1B, a heat radiation block 40 having a plurality of insertion grooves 42 formed on one surface is manufactured, and a plurality of heat sinks 40 are inserted into and fixed to the insertion grooves 42 of the heat radiation block 40. After manufacturing the heat dissipation fins 50 separately, the above problem is solved by forcibly fitting the end portion of the heat dissipation fin 50 to the insertion groove 42 of the heat dissipation block 40 to fit.

However, the separation and coupling type of the radiator 10, as shown enlarged in Figure 1b, by inserting and fixing the end of the heat dissipation fin 50 in the insertion groove 42 of the heat dissipation block 40 A fine gap may be formed, and as a result, the heat transferred to the heat dissipation block 40 is not properly transmitted to the heat dissipation fins 50, thereby deteriorating heat dissipation performance.

In this case, in order to solve this problem, by further performing a welding process for filling the gap between the end of the insertion groove 42 and the heat radiation fin 50 of the heat dissipation block 40, the workability and productivity are not good, thereby The problem of increasing production cost is being raised.

2 is a flow chart showing a manufacturing process of a lamp radiator according to an embodiment of the present invention.

In addition, Figure 3a is a schematic view showing a process for manufacturing a lamp radiator using a manufacturing apparatus for a lamp radiator according to an embodiment of the present invention, Figure 3b is a lamp according to an embodiment of the present invention It is a block diagram of a radiator for a lamp manufactured using a manufacturing apparatus of a radiator for heat.

First, referring to FIG. 2, a method of manufacturing a radiator for a lamp according to an embodiment of the present invention comprises the steps of manufacturing a heat dissipation block 40 having a plurality of insertion grooves 42 formed at regular intervals on one surface (S10) ) And a step (S20) of manufacturing a plurality of heat dissipation fins 50 into which one end is inserted into the insertion groove 42 of the heat dissipation block 40 may be performed.

That is, the heat radiating block in which a plurality of insertion grooves 42 are formed at regular intervals on the other side corresponding to one surface of the heat radiating block 40 in which the high-brightness LED 20 and the substrate 30 are coupled in close contact ( It may include a step 10 of manufacturing 40), such a heat dissipation block 40 may be produced by die casting a molten aluminum material by a pre-made mold.

In addition, a plurality of heat dissipation fins 50 can also be manufactured by die casting a molten aluminum material by a pre-made mold.

As described above, when the heat dissipation block 40 and the heat dissipation fins 50 respectively manufactured separately are provided, and when they are combined in an orthogonal direction, as shown in FIGS. 2 and 3A, 3B, The heat sink block 40 is immersed in the oxidation tank 60 (S30), the anodizing, and the ends of the plurality of heat sink fins 50 are inserted into the heat sink block 40 immersed in the oxidation tank 60.

Here, the hoist 70 can move the other end of the plurality of heat dissipation fins 50 in a gripping state or release the gripping in the state where the other end of the heat dissipation fin 50 is gripped. And the release of the grip may be performed manually or automatically.

Therefore, in the state in which the heat radiation block 40 in which the insertion grooves 42 are formed is immersed in the oxidation tank 60 containing the oxidizing solution, when the anode is applied to the heat radiation block 40, the entire surface of the heat radiation block 40 An anodized film is formed by anodizing at this time, and the ends of the heat dissipation fins 50 are inserted into the heat dissipation block 40 as the hoist 70 holding the other end of the heat dissipation fins 50 is lowered at the same time.

At this time, the plurality of heat dissipation fins 50 are also immersed in the oxidizing liquid of the oxidation tank 60, so that the ends thereof are inserted into the insertion grooves 42 of the heat dissipation block 40, so that the heat dissipation block With respect to (40), a plurality of heat dissipation fins 50 are coupled in an orthogonal direction.

On the other hand, as described above, the heat dissipation block 40 is formed anodized by anodizing on the surfaces of the plurality of insertion grooves 42 as anodizing is performed, and thus an oxide film is formed on the surfaces of the insertion grooves 42 and At the same time, the end of the heat dissipation fin 50 is inserted into the insertion grooves 42. As between the insertion groove 42 and the heat dissipation fin 50 end, it is as if it is an integral shape without voids by the coating layer 80. The bond is made.

Therefore, the heat transferred to the heat dissipation block 40 is heat-conducted to the heat dissipation fins 50 without heat loss, so that the heat dissipation block 40 and the heat dissipation fins 50 are as if they were integrally manufactured. Will be able to exert.

That is, conventionally, when the heat dissipation block 40 and the plurality of heat dissipation fins 50 that form mutually orthogonal directions are integrally manufactured, the lengths of the heat dissipation fins are changed in correspondence with the manufacturing convenience and the applied lamp shape as described above. There was a difficult problem, but in the case of a radiator for a lamp manufactured by a manufacturing method and a manufacturing apparatus according to an embodiment of the present invention, the heat dissipation block 40 and the plurality of heat dissipation fins 50 are manufactured separately, and as if they are integrally formed. Since it is possible to combine, the manufacturing convenience is greatly improved, as well as the advantage of being able to apply heat dissipation fins 50 of various lengths or shapes in response to the shape of the applied lamp.

In addition, as the heat dissipation block 40 and the plurality of heat dissipation fins 50 are anodized in the oxidation tank 60 and combined to form an integral type, the surfaces of the heat dissipation block 40 and heat dissipation fins ( By anodizing simultaneously on the surfaces of 50), the effect of simplifying the manufacturing process can also be provided.

4 is a configuration diagram of another type of lamp radiator manufactured by using the manufacturing apparatus of the lamp radiator according to an embodiment of the present invention. , As shown in FIG. 4, it is possible to manufacture a radiator for a lamp having heat radiating fins 50-1 of various shapes and lengths.

<Other embodiments>

5A and 5B, 6 and 7 are schematic views showing a process of manufacturing a different type of lamp radiator using a manufacturing apparatus for a lamp radiator according to another embodiment of the present invention, and FIG. 8 Is a flow chart showing a manufacturing process of a lamp radiator according to another embodiment of the present invention.

For reference, in describing another embodiment of the present invention, repeated description of the same parts as in the previous embodiment will be omitted.

5A and 5B, an apparatus 100 for manufacturing a radiator for a lamp according to another embodiment of the present invention includes an oxidation tank 60 in which an oxidizing liquid is accommodated, and a heat dissipation block immersed in the oxidation tank 60 In a configuration including a hoist 70 in which lifting is performed in a state where the other end of the heat dissipation fin 50-2 is gripped so as to insert the end of the heat dissipation fin 50-2 into the insertion grooves 42 of the 40. It can be done.

However, the radiator for a lamp according to another embodiment of the present invention has a heat radiation block 40 in which a plurality of insertion grooves 42 are formed on one surface, and a cone shape heat radiation fin whose cross-sectional area gradually decreases as it goes upward. A combination of (50-2) can be applied.

At this time, the heat dissipation block 40 and the plurality of heat dissipation fins 50-2 may also be made of a molten aluminum material by die casting by a pre-made mold, respectively, and they may be formed in a configuration in which they are coupled in an orthogonal direction to each other. .

In addition, the apparatus for manufacturing a radiator for a lamp according to another embodiment of the present invention forms a cone shape in a state in which a plurality of radiating fins 50-2 are coupled to the insertion grooves 42 of the radiating block 40. A plurality of heat dissipation fins (50-2) at least one or more heat dissipation plate 110 may be made of a configuration further comprising a pressing portion 160 for simultaneously coupling with anodizing.

Here, the pressing unit 160 is provided in a pair facing each other, but at least one pair of grip holders 120 spaced apart at regular intervals, and in a direction parallel to one side of the grip holder 120 An elastic member 140 installed between the support part 130 extending and formed vertically adjacent to the support part 130 and the pressing protrusion for pressing the uppermost support part 130 among the support parts 130 ( 150).

The pair of grip holders 120 arranged in opposite directions are gripped at both ends of the heat dissipation plate 110 so that the heat dissipation plate 110 is level, and an operator manually removes the heat dissipation plate 110. Both ends may be gripped, or both ends of the heat dissipation plate 110 may be gripped by electric transmission.

For reference, in the drawing for supporting another embodiment of the present invention, the heat radiation plate 110 coupled to the heat radiation fins 50-2 in the shape of cones are all shown as one example, but this is one embodiment As it is only, the heat radiation plate 110 may be a plurality of one or more.

However, when a plurality of heat dissipation plates 110 are stacked here, as the heat dissipation plate 110 located on the upper side is formed, a pass hole 112 having a small size is formed to correspond to the heat dissipation fin 50-2 having a cone shape. Can be.

That is, the heat dissipation fin 50-2 has a cone shape in which the cross-sectional area gradually decreases toward the upper side, and the cross-sectional area becomes larger as it is directed toward the lower side.

Therefore, the through hole 112 of the heat dissipation plate 110 inserted into the lower side of the heat dissipation fin 50-2 is relatively large, and the through hole 112 of the heat dissipation plate 110 located on the upper side is relatively small. do.

In other words, when all four heat dissipation plates 110 coupled in a direction orthogonal to the heat dissipation fins 50-2, the passage hole 112 of the heat dissipation plate 110 positioned fourth from the top is the largest, The passing hole 112 of the third heat dissipation plate 110 is the second largest, the passing hole 112 of the second heat dissipation plate 110 is the third largest, and the first heat dissipation plate The passage hole 112 of 110 may be formed to be the smallest.

For reference, the through holes 112 of the heat dissipation plates 110 are preferably formed so that the inner circumferential surface forms a vertical surface. That is, when the inner circumferential surfaces of the through holes 112 are formed to be inclined to correspond to the cone-shaped heat dissipation fins 50-2, if there is no tolerance, the insertion may not be properly performed, so the through holes ( 112) by making the inner circumferential surface to form a vertical surface, it is preferable that the fixing is made at a point where the diameter of the lower portion of the through hole 112 coincides with the diameter of the radiating fin 50-2.

In this way, the heat dissipation fins 50 of the radiator immersed in the oxidizing tank 60 in a state in which the heat dissipation plates 110 having a large size of the passage hole 112 are sequentially fixed to the holding holders 120 of the pressing portion. When the pressing portion 160 is lowered toward -2), the elastic members 140 disposed between the supporting portions 130 are compressed by the pressing force of the pressing protrusion 150 while being pressed against the heat dissipation fins 50-2. In the orthogonal direction, a plurality of heat dissipation plates 110 are forcibly fitted at regular intervals to be combined.

At this time, by the compression force of the elastic members 140, the heat dissipation plates 110 are pressurized to the point where the diameter of the through hole 112 is the same as the diameter of the heat dissipation fins 50-2, forcibly fitting. Fixing is done in a completely tight state.

In this way, the heat dissipation plate 110 by the pressing unit 160 against the radiator immersed in the oxidation tank 60 in a state in which the heat dissipation block 40 and the heat dissipation fin 50-2 are coupled to the heat dissipation fins 50- 2) In the process of inserting and fixing, in addition to anodizing, inserting and fixing are performed.

Therefore, when the anode is applied to the radiator immersed in the oxidation tank 60 containing the oxidizing liquid, an oxide film is formed by anodizing on the entire surface of the radiator, and at this time, the heat radiating plate 110 is immersed in the oxidation tank 60 at the same time. In addition, an anodized film is formed by anodizing.

Therefore, as the pass holes 112 of the heat dissipation plate 110 are also formed on the inner circumferential surface thereof, the space between the pass holes 112 and the outer circumferential surface of the heat dissipation fins 50-2 is as if the voids were not formed by the coating layer 200. The coupling is made as if it were an integral shape.

Therefore, the heat transferred to the heat dissipation block 40 is heat-conducted to the heat dissipation fins 50-2 without heat loss, and the heat transferred to the heat dissipation fins 50-2 is heat dissipation plate 110 again. As the heat conduction is performed, heat dissipation performance can be further improved.

For reference, although not separately shown, as a convection of air is formed by forming a separate through hole (not shown) around the through holes 112 inserted into the heat dissipation fins 50-2 in the heat dissipation plate 110. Due to this, it is possible to further improve the heat dissipation effect, and further improve the heat dissipation performance by increasing the contact area with air by forming a separate concavo-convex (not shown) around the through hole 112 of the heat dissipation plate 110. It might be.

In addition, while anodizing the radiators immersed in the oxidizing tank 60 in a state in which the heat dissipation plates 110 having different through holes 112 having different diameters are fixed (S500) to the pressing unit 160, pressure is applied. By immersing the heat dissipation plate 110 in the oxidation tank 60 as the portion 160 descends, the heat dissipation plates 110 are spaced apart at regular intervals in a direction orthogonal to the heat dissipation fins 50-2. Insert and combine (S600) to be stacked.

Finally, after the anodizing of the oxidation tank 60 is stopped, after the release holder 120 of the pressing unit 160 against the heat dissipation plate 110 is released, the pressing unit 160 is raised and then the oxidation tank When the radiator is pulled out from the 60, as shown in FIG. 7, the heat dissipation block 40, the plurality of heat dissipation fins 50-2, and the heat dissipation plate 110 are completed as if they were integrally formed. You can.

At this time, the end coupling portion of the heat dissipation fins 50-2 to the insertion grooves 42 of the heat dissipation block 40 and the outer diameter of the heat dissipation fin 50-2 and the through hole 112 of the heat dissipation plate 110 When the anodizing treatment is performed, the bonding sites are filled without voids to maintain the bonding as an integral type, so that the thermal conductivity is improved and the heat dissipation performance can be greatly improved.

That is, the heat dissipation block 40, the heat dissipation fins 50-2 and the heat dissipation plate 110 are manufactured separately, but they can be combined as if they are integral, thereby maintaining the heat dissipation performance while maintaining the production convenience. Of course, the anodizing treatment is simultaneously performed on the entire radiator as well as greatly improved, and thus the production cost can be reduced by reducing the number of work hours.
