The problems of the conventional outdoor high power LED lighting lamp will be described with reference to FIGS. 1 to 3. As illustrated in FIG. 1, the outdoor high-power LED lighting lamp is composed of a transparent cover 101 and a heat sink 102 connected to the transparent cover 101. More specifically, the transparent cover 101 is sealed by the heat sink 102 and the packing ring 106. The transparent cover 101 is generally made of polycarbonate, and the packing ring 106 is made of rubber or silicone material. On the front of the heat sink 102, an LED-mounted printed circuit board 104 is mounted, and an LED 105 is mounted on the front of the printed circuit board 104 to emit a light source through the transparent cover 101 to the outside. . In order to improve the heat conduction of the heat sink 102, a plurality of heat sink fins 103 are formed on the rear surface of the heat sink 102 to discharge heat generated from the LEDs by air cooling.

2 is a view showing an installation form of a high-power LED lighting for outdoor use. 2 (a) is a form in which the transparent cover 101 is installed facing downward, Figure 2 (b) is a form in which the transparent cover 101 is installed facing the side, Figure 2 (c) is a transparent cover 101 ) Is shown inclined at a predetermined angle while facing downward. As shown in Figure 2 (a), when the transparent cover 101 is installed to face downward, the heat generated by the LED 105 heats the air inside the transparent cover 101, and the heated air As it becomes lighter and moves upward, air heated toward the LED 105 is collected. 2 (b), when the transparent cover 101 is installed to face the side, the heat generated by the LED 105 is heated and moves to the top, so as shown in the drawing, the top of the transparent cover 101 Go to and gather. Figure 2 (c) is a case where the transparent cover 101 is installed in an inclined state, and in this case, as shown in the figure, the upper portion of the transparent cover 101 is moved to gather.

FIG. 3 shows the case where the power is applied to the LED 4 and turned ON (FIG. 3 (a)) and when the power is turned off (FIG. 3 (b)). When power is applied to the outdoor high-power LED lighting and the internal power is about 200W to 1.2KW, the temperature in the transparent cover (1) rises to 70 ~ 100 ℃ and heats the internal air, and the heated air expands, resulting in internal pressure. When the internal pressure is increased and the external atmospheric pressure is greater, the expansion pressure is applied to the outside, so that the stress of the sealing portion 106, the packing ring 106, is forced to be exerted. FIG. 3 (b) shows the light-off state. When the light is off, the temperature in the transparent cover 101 decreases to 20 to 50 ° C, which is the ambient temperature, and the inside is vacuumed due to the temperature drop of internal air in the light-off state. In the state, the external atmospheric pressure acts inside the transparent cover 101. Accordingly, the inside of the transparent cover 101 is vacuumed so that outside air or moisture can be introduced. That is, repetitive stress due to lighting and extinguishing of the lighting lamp acts on the packing ring 106, and the sealing function of the packing ring 106 may be lost due to repeated stress, and the transparent cover ( 101) Moisture flows into the inside to form water droplets, thereby causing defects such as electrical shorts on the PCB inside the transparent cover 101, thereby shortening the life of the lighting lamp. In addition, since different materials such as a transparent cover (PC material) and a heat sink (aluminum), which are heterogeneous materials, are fastened, a problem of waterproof failure may occur due to continuous shrinkage and expansion. In particular, in the high temperature and high humidity environment, such as the summer rainy season or Southeast Asia, poor waterproofing may occur more frequently.

4 to 9, the air vent 1 according to the present invention will be described in detail. As shown in Figure 4, the air vent 1 includes a cover 10, a bolted body 30, and a filter 20 attached to the front surface of the bolted body 30 and a bolted body 30. It is composed of a packing ring 40 that is inserted into the threaded portion 36 and fastened together. The cover 10 includes a top plate 11 and side plates 12, which are spaced at regular intervals from the edges of the top plate 11, and three fastening hooks 13 formed inside the bottom of each side plate 12. ), And a stopper 14 formed inside the upper side of the side plate 12. Typically, the spacing of the side plates 12 may be formed at an interval of 120 ° so as to correspond to the hexagonal head 31 of the bolted body 30.

The bolt-shaped body 30 is formed integrally with the hexagonal head 31 on which the side plate 12 of the cover 10 is mounted, and on the lower portion of the hexagonal head 31 and mounted on the lighting cover 101 It is formed through a threaded portion 36, a hexagonal head 31 and a threaded portion 36, and is formed of a through hole 37 through which air flows in and out. Specifically, the hexagonal head 31 is formed from the upper surface 32, the side plate guide grooves 33 formed on the hexagonal side surfaces of the head 31, and the upper side of the side plate guide grooves 33 from both sides to the bottom. The extended stopper seating projections 34a, the hook stopper projections 34b formed by connecting the lower sides of the stopper seating projections 34a to each other, and the filter mounting portion 35 formed on the upper surface 32 of the head 31 And, the filter mounting portion 35 is made of a buffer groove 38 that is formed stepped inside. The hexagonal head 31 may be formed in a hexagonal shape for easy mounting using an instrument. Accordingly, the air vent 1 can be mounted or detached using a hexagon wrench or a monkey spanner. In addition, the stopper seating projections (34a) are formed on both sides so that the stopper (14) formed on the inner top of the side plate (12) of the cover (10) can no longer move to the lower side, and the two stopper seating projections (34a) are lower It is extended to, and connected to each other at the bottom to form a hook seating projection (34b). The fastening hook 13 is seated on the hook seating projection 34b so that the position of the cover 10 is fixed.

The buffer groove 38 is made of a larger diameter than the through hole 37 so that the air passing through the filter 20 can be temporarily stored.

The stopper seating projections 34a are formed on both sides to allow the fastening hook 13 to be seated and to guide the fastening hook. Therefore, the stopper seating projection 34a serves as a guide, and the fastening hook 13 is easily guided along the stopper seating projections 34a on both sides, and can be finally fastened to the hook seating projections 34a.

The filter mounting portion 35 is formed in a ring shape on the upper surface 12 of the body head 31 and the outer mounting portion 35-1 and the outer mounting portion 35-1 is formed radially in the buffer groove 38 of the It consists of a number of inner supports 35-2 extending to a certain distance. The inner support portion 35-2 may be radially extended in the form of a bar. The inner support portion 35-2 is formed of three or more, preferably four. Since it consists of four, it assists the adhesive force of the filter and further supports the filter, so that it is possible to prevent the filter from being damaged when the filter is mounted. In addition, it can also serve to improve the adhesion of the filter.

10 to 11, the transparent cover 101 of the lighting is formed with a through hole 107 in which a thread is formed on the inner circumferential surface. This is to allow air in and out of the atmosphere to flow through the through hole 107. However, since the moisture in the atmosphere should not be introduced as much as possible, an ultra-fine membrane filter capable of introducing only gas is used. As shown in Figure 7, the filter is composed of a disc-shaped filter 20, the disc-shaped filter 20 is formed of an adhesive on the edge of either side of the filter body 21 and the filter body 21 An adhesive portion 22 is provided, and an adhesive is not formed in the central portion 23 of the filter body 21 to allow gas to flow in and out through the central portion 23. Since the adhesive portion 22 is formed on the disc-shaped filter 20, it can be easily attached to the filter mounting portion 35. Also, when the adhesive force of the disc-shaped filter 20 is weakened, remove it and attach a new filter 20. You may. A release sheet (not shown) may be attached to the surface on which the adhesive portion 22 is formed to be provided together with a lighting lamp. The user may remove the release paper attached to the portion where the adhesive portion 22 of the filter 20 is formed, and then attach it to the filter mounting portion 35 and use it. Since the through hole 107 is formed in the transparent cover 101, it is possible to easily grasp the state of the air vent 1, and further, there is an advantage of easy maintenance. In addition, since the air vent 1 is attached to the front side of the transparent cover 101, the pressure inside and outside of the transparent cover 101 becomes the same even if the lighting lamp is repeatedly lit and turned off, thereby providing a sealing function. No stress is applied to the packing ring 106. Therefore, even if the packing ring 106 is used for a long time, the waterproof function can be faithfully performed.

In addition, since the threaded portion 36 is formed of a thread, it is easy to attach and detach, and the head 31 is formed in a hexagonal shape, so that it can be mounted using a mechanism such as a monkey spanner when fastening.

Although some embodiments have been described by way of example, the fact that the present invention can be embodied in various other forms without departing from its spirit and scope is obvious to those skilled in the art. Therefore, the above-described embodiments are to be regarded as illustrative rather than restrictive, and all implementations within the scope of the appended claims and equivalents thereof will be included within the scope of the present invention.
