Fig. 2 is a schematic view showing air circulation of the composite material streetlight housing of the present invention. Fig.

As shown in FIG. 2, a PCB substrate 180 for the public and a heat sink 190 for cooling the heat are installed inside the streetlight housing.

In order to cool the PCB board 180 and the heat, air circulation is required inside the street lamp housing. Therefore, a plurality of air openings 160 through which the air flows into the side of the street lamp housing are formed. In order to prevent rainwater from entering the air, And an upper partition wall 111 protruding downward is formed on the upper partition wall 122 and the inner partition wall 121 so as to be positioned on the upper partition wall 122 have.

Since the SMPS (Switched-mode power supply) driven in association with the PCB substrate in the inside of the streetlight housing is a conventional structure, the illustration and explanation are omitted.

A drain hole (123) is formed between the outer partition wall (122) and the inner partition wall (121) so as to allow the rainwater to flow vertically through the lower plate.

In Fig. 2, A represents a flow of air, and W represents a flow of rainwater.

As shown in FIG. 4, the composite street lamp housing 100 of the present invention includes two glass fibers (GF) and carbon fibers (CP) in the lower metal mold 220 in the form of a street lamp housing, And the upper mold 210 is pressed to manufacture the street lamp housing 100.

At this time, the glass fiber GF and the carbon fiber CP are arranged to be spaced apart from each other, and the glass fiber GF and the carbon fiber CP are spread by the pressing force of the upper mold 210, So that the lamp housing 100 can be manufactured.

The glass fiber (GF) and the carbon fiber (CP) used for manufacturing the streetlight housing 100 are in the state of SMC.

Sheet Material Composite (SMC) is a semi-solid, viscous, 1 to 2 mm sheet-like raw material such as clay.

In the present invention, when the glass fiber is an SMC type glass fiber reinforced polymer (GFRP) or glass fiber reinforced plastic (GFRP), the carbon fiber is an SMC type carbon fiber reinforced concrete (CFRP) Polymer) or a carbon fiber plate (CF).

The two SMCs are stacked in accordance with the weight of the final street lamp housing when they are put into the lower mold 220. When the upper mold 210 is pressed, molded, heated and cured at a certain pressure, The materials are not bonded to each other and are not separated.

Therefore, the upper and lower molds are preheated between 110 and 130 DEG C, and compression molding is performed with a force of 1000 to 1500 ton.

After heating under pressure, the substrate is kept in a heated state for 3 to 5 minutes to be cured, followed by cooling for about 3 to 5 minutes.

Particularly, the glass fiber board is manufactured so as to contain an epoxy resin as a hardening material, so that the tensile strength is maintained at 100 to 120 MPa.

5 is a schematic diagram of a method of manufacturing a streetlight housing using three different SMCs, according to another embodiment of the present invention.

As shown in FIG. 5, three SMCs are used, and the street lamp housing 100 is manufactured by applying a high strength carbon fiberboard (CF), a high strength glass fiberboard (GF1), and a low strength glass fiberboard (GF2).

That is, the high-strength glass fiberboard (GF1) and the low-strength glass fiberboard (GF2) differ in the content of carbon fiber in the glass fiber. High strength and low strength.

At this time, the conditions for molding the street lamp housing are the same as those described above.

Therefore, the present invention has a remarkable effect in that it is easy to manufacture the street lamp housing, the use of the manufactured street lamp housing is convenient, the strength is great, the strength of the street lamp housing is different, and the corrosion resistance is excellent.
