As is well known, the floodlight is installed indoors or outdoors so that light of desired brightness can be inspected in architectural structures, large monuments, various stadiums, various factory facilities, and industrial facilities. These floodlights are mainly made of high-intensity discharge lamps. The surface where the light is projected is made of glass or acrylic, which is excellent in transmittance. It is installed at an optimal position for enhancing the lighting effect, They are arranged at proper intervals and projected in a desired direction.
Metal halide lamps such as metal halide lamps and sodium lamps, such as halogen lamps, are used as light sources used for such light projections. These lamps require a large amount of electric power, short service life, and long lighting time. And pollute the environment.
Therefore, recently, LEDs which require low power consumption and have semi-permanent lifespan characteristics are widely applied as light sources in terms of illumination improvement and energy saving.
A light emitting diode (LED), a light emitting diode (LED), a light emitting diode (LED), a light emitting diode (LED), a light emitting diode And a heat sink attached to the back surface of the top cover to cool the heat generated by the LED.
On both sides of the top cover, a mounting frame for fixing the illumination lamp to the floor, ceiling or wall surface is installed. At this time, the mounting frame and the top cover are bolted to each other while being in surface contact with each other, There is a disadvantage that it is difficult to adjust the angle of the user's desired angle by slipping the mounting frame in the top cover in the process of tilting the top cover.
In addition, there is a problem that rainwater seeps through the fastening holes to which the bolts are fastened when raining, thereby damaging electrical parts such as a substrate.

1 to 3, the outdoor light 100 of the present invention mainly includes an LED 12, a top cover 20, a side cover 30, a heat sink 40, and a mounting frame 50 .
The LED (Light Emitting Diode) 12 is mounted on the printed circuit board 10 as a light emitting means and emits light to an external power source.
The top cover 20 is formed by injection molding with a transparent plastic material and has a receiving space 22 for receiving the printed circuit board 10 on which the LED 12 is mounted, .
An insertion groove 24 is formed in the front and rear of the inner housing space 22 of the top cover 20. A protrusion 49 protrudes from the lower end of the heat sink 40, .
When the LED 12 accommodated in the accommodation space 22 emits light from an external power source, the top cover 20 transmits the light to the outside.
The heat dissipation plate 40 is in contact with the upper surface of the printed circuit board 10 and has a flat plate shape as a means for cooling the heat generated by the LED 12. At least one heat dissipation fin 42 A protrusion 49 protrudes from the top and rear of the upper surface of the heat sink 40. The protrusion 49 prevents the heat sink 40 from entering the space of the top cover 20 The heat sink 40 is securely fixed to the top cover 20 while being inserted into the insertion grooves 24 formed in the front and rear of the receiving space 22, Thereby preventing the water from penetrating into the accommodation space 22 of the waterproof case 22 so as to implement the waterproof function.
When the LED 12 emits heat, the heat sink 40 functions as a heat pipe and conducts the heat to the heat sink 42. At the same time, the heat sink 40 is connected to the outside air And the LED 12 is cooled.
A heat dissipation box 44 is further formed at the center of the heat dissipation plate 40 to increase heat conduction efficiency of the heat dissipation plate 40. The heat dissipation box 44 is formed with a space 46 therein and the shaft pin 70 assembled to fix the mounting frame 50 to the side cover 30 can be fitted to the bottom surface of the space 46. [ So that a fastener 48 is further formed. Also, it is preferable that the space 46 in which the fastener 48 is formed is configured to fill the silicone 80 in consideration of airtightness to realize a waterproof function.
The side cover 30 is integrally formed on both sides of the top cover 20 and is provided for connecting the mounting frame 50 to the top cover 20. [
A hole 32 for fastening the shaft pin 70 is formed at the center of the side cover 30 and a gear 34 is formed on the outer surface of the side cover 30 along the circumferential surface of the hole 32. [ .
The mounting frame 50 is a frame used as means for fixing outdoor lighting to use. The arm 52 is vertically bent so that the arm 52 faces forward, (60) to the outer surface of the side cover (30) integrally formed on both sides of the side cover (20).
The connection cap 60 is formed with a space 62 in which an arm 52 of the mounting frame 50 is inserted and a shaft hole 70 for fastening the shaft pin 70 is formed at the center thereof. And a gear 66 for engaging with the teeth 34 of the side cover 30 is formed on the inner surface of the connecting cap 60 along the circumference of the hole 64. [
The connecting cap 60 is closely attached to the outer surface of the side cover 30 in a state where the connecting cap 60 is assembled to the arm 52 bent downward on both sides of the mounting frame 50. In this state, The top cover 20 is assembled to be rotatable in the mounting frame 50 by coupling the shaft pin 70 to the holes 60 and the holes 32 and 64 formed in the side cover 30 . At this time, the arm 52 is formed with a connection hole 54 for connecting the hole 64 of the connection cap 60 and the hole 32 of the side cover 30 so that the shaft pin 70 is inserted into the connection cap 60 so as to be inserted into the hole 64 of the side cover 30 and the hole 32 of the side cover 30.
After the angle of the top cover 20 is adjusted by the user through the gears 34 and 66 engaged with each other by the connection cap 60 and the side cover 30, It is possible to prevent a situation in which the top cover 20 whose angle has been adjusted slips due to its own weight and the angle can be changed.
Hereinafter, the operation of the outdoor lighting according to the present invention will be described with reference to FIGS. 1 to 3 attached hereto.
The assembly of the outdoor light 100 according to the present invention is performed by first inserting the printed circuit board 10 on which the LED 12 is mounted in the accommodation space 22 of the top cover 20, The mounting frame 50 is fastened to the side cover 30 provided on both sides of the top cover 20 with the shaft pin 70 and then the mounting frame 30 is mounted on the mounting cover 30. [ (50) to the place of use so that outdoor lighting is used.
Meanwhile, in order to adjust the angle of illumination in the course of using the outdoor lighting, when the top cover 20 is pulled or pushed while being held by hand, the top cover 20 is rotated about the pivot pin 70 A gear 34 formed on the outer surface of the side cover 30 and a connecting cap 60 used to assemble the mounting frame 50 to the side cover 30 are mounted on the side cover 30, The angularly controlled top cover 20 is maintained in a state in which the angle is adjusted without continuously slipping without using a separate fixing means even if its own weight is applied, .
