After interposing the support 50 to the ballast fixing plate 40, the heat sink 10, and the support 50 to each other by fixing bolts 70 to each other to fix.

Then, the tempered glass 33 is inserted into the tempered glass fixing hole 32a of the base 32.

Then, the ballast 90 is fixed to the upper surface of the ballast fixing plate 40 and one inner surface of the base 32, respectively.

Then, the four corners of the heat sink 10 are placed on the upper surface of the support portion 32b of the four parts formed on the inner upper surface of the base 32 and fixed with fixing bolts, and then the stabilizers 90 on both sides are connected to the conductive wires ( 100 to the circuit board 20, respectively.

When the lower portion of the cover 31 of the housing 30 is fixed to the one side edge portion of the base 32 corresponding thereto, the assembly of the luminaire is completed.

Then, the support base body 61 of the luminaire support 60 is placed on the pole 80 to pass through the fixing strap 61d through the fixing holes 61c on both sides thereof, and is tied to the pole 80.

Then, one side of the support tube 61a of the luminaire support 60 fixed to the pole 80 is inserted into the hollow portion of the other side of the luminaire base 32 of the luminaire where the assembly is completed, in which case the fixed After inserting one end of the piece 61b into the fixing recess 32d of the base 32 of the luminaire, the support tube 61a of the luminaire support 60 is inserted into the hollow portion on one side of the base 32, and then fixed. Tightening the bolt 110 to the lamp fixture may be fixed to the fixture support 60.

In the present invention, as shown in Figs. 9B, 9C, 10A and 10B, one fixing recess 32d formed in any one of the upper, lower, left and right portions of the other end of the base 32 is provided. Or the fixing protrusion 61d or the support formed on any one of the upper, lower, left and right sides of the outer surface of the support tube 61a of the luminaire support 60 corresponding to the fixing recess 32d formed in two or more portions. Support tube 61a of the luminaire support 60 in the hollow on one side of the base 32 while inserting the fixing protrusion 61d formed in at least two of the upper, lower, left and right portions of the outer surface of the tube 61a. After inserting, tighten the fixing bolt 110 to fix the luminaire to the luminaire support (60).

Therefore, the fixing protrusions 61d of the luminaire support 60 corresponding to the one or more fixing recesses 32d of the base 32 can be easily inserted and fixed, and the installation state of the security lamp or the street lamp is horizontal. It is easy to maintain.

Therefore, even if someone other than the worker who installs the luminaire on the pole does not tell whether the luminaire is installed straight from the bottom, the worker who performs the installation work on the pole is formed in the hollow part formed at one end of the base 32 of the luminaire ( When fitting the support tube 61a of 60, it is only necessary to insert the fixing piece 61b or the fixing protrusion 61d of the luminaire support 60 into the fixing recess 32d formed at one end of the base 32. It is easy, quick and easy to install the lamp fixture straight on the pole with only one worker installing the lamp.

Fixing bolts by inserting the support tube 61a and the fixing piece 61b or the fixing protrusion 61d of the luminaire support 60 into the hollow part and the fixing recess 32d of one end of the base 32 of the luminaire where the assembly is completed. After fixing by tightening with 110, the luminaire support 60 coupled to the luminaire may be tied to the jeonju 80 with a fixing string 61d through the fixing hole 61c to install the luminaire to the jeonju. Do.

The lighting device of the present invention installed as described above is configured to be circuitd by a circuit of the circuit board 20 when power is applied to the LED lighting device by the user to light up the LEDs 21 respectively bonded to the circuit board 20 of the lighting device. Power is applied to the LEDs 21 connected to the substrates 20, respectively, so that the plurality of LEDs 21 are turned on.

As the LEDs 21 light up, the light from the LEDs 21 is irradiated downward of the luminaire.

As the light is emitted from the LEDs 21, high heat is generated in each of the LEDs 21. The high heat is generated by the heat dissipation plate 10 which is fixed to the circuit board 20 in contact with the circuit board 20. Thus, heat conduction is made of each of the heat dissipation fins 11. At this time, since the heat dissipation area of each of the heat dissipation fins 11 is formed to be maximized, high heat is efficiently radiated through the heat dissipation fins 11.

Therefore, the high heat radiated from the heat dissipation fins 11 is discharged in the upper direction, the front and the rear direction of the space formed between the heat dissipation fins 11, and then moves downward toward the base 32, and the base 32 The heat is dissipated to the outside through the heat dissipating plate 10 or the tempered glass 33 and the circuit board 20 and the space 32c of the base 32.

Therefore, the high heat generated from the LED 21 of the luminaire can be smoothly dissipated to the outside atmosphere so that the interior of the LED luminaire can maintain a proper temperature so that the life of the LED is not reduced and luminous efficiency is not reduced. In addition, the efficiency as a luminaire can be greatly increased.

In the present invention, the heat dissipation fins 11 ', 12, 12', 13, 14, and 15, which are other embodiments of the heat dissipation fins 11, are used, respectively. The same action effect or more action effects can be obtained.

That is, the heat dissipation fins 12, 13, 14, and 15 have high heat radiated from the heat dissipation fins 12, 13, 14, and 15, respectively. After being discharged in the upper direction, the front and the rear direction of the space between them, and moving downward toward the base 32, the heat dissipation fin 11 'can be exerted in the same manner as the heat dissipation fin (11). ) 12 'is the left and right sides through each of the left and right vents 11'b or the ventilation holes 12'b in addition to the upper direction or the front and rear directions of the space between the heat dissipation fins 11' and 12 '. Since the high heat is also emitted in the direction, it is possible to exert a better effect than the effect of the release pins (11) (12) (13) (14) (15).

The heat dissipation fins 13, 14, and 15 are smaller in size than the heat dissipation fins 13, 14, and 15 of the heat dissipation fins 13, 14, and 15. The high heat is rapidly released in the vertical direction or the horizontal direction of the space between them. In addition, since the shape of the portion of the heat dissipation fins 13, 14, 15 is large and high, the shape of the portion is formed in a curved surface, so that the space portion between the heat dissipation fins 13, 14, 15 is vertical or horizontal. In the direction of the high heat is easily released. Therefore, the high heat can be efficiently released by the curved shape of the heat radiation fins 13, 14, 15.

In addition, when using a luminaire provided with a heat radiation and a light emitting portion (A) to which the circuit board 20 ', 20 "and the heat sink 10' which are other embodiments of the circuit board 20 or the heat sink 10 are applied, respectively. High heat is also efficiently radiated through each of the small flat plates or curved circuit boards 20 '20 "

That is, as shown in FIG. 5A, since the circuit boards 20 'are separated and installed, high heat in the circuit boards 20' generated due to the high heat generated by the LEDs 21 is also efficiently radiated. It becomes possible.

In addition, as shown in Figure 5b, the heat sink 10 'is formed in a curved shape so that the area is wide, and the circuit board 20 "fixed in contact with the heat sink 10' is also separated by several Since the heat sink 10 is formed in the shape of the heat sink 10 formed of a flat plate and the circuit board 20 of the flat plate fixed to the heat sink 10, the heat generated from the LED 21 to the heat sink 10 'and the circuit board ( 20 ") also allows for efficient heat dissipation.

Therefore, the embodiment of the effect of the parts other than the heat radiation fins 11 ', 12, 12', 13, 14, 15, the circuit boards 20 ', 20 ", and the heat sink 10', which are the above-described embodiments Since the same as 1, the overall operation of each of the other embodiments will be omitted in order to avoid duplication.
