Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing refer to like elements.

1 is an exploded perspective view of the main body and the angle adjustment bracket in the lighting device of the present invention.

As can be seen from FIG. 1 , the lighting device of the present invention is based on including a lighting unit 10 , a controller, a shade assembly, and an angle adjustment bracket 100 .

The lighting unit 10 of the present invention is a main component for providing illumination light through illumination, and specifically consists of a main body 20 and an illumination 30 .

The main body 20 is provided with a physical volume in the form of a housing or a case, and an electric/electronic configuration (eg, a power cable, a power supply, etc.) for flickering the lighting 30 including a detailed configuration of a controller to be described later. It performs the function of accepting

Such a main body 20 is illustrated as a structure close to a cylindrical shape in the drawings. Of course, the shape of the main body 20 is not limited to the cylindrical shape and may be formed in various three-dimensional shapes.

In addition, when the lighting device of the present invention is used for a mobile purpose, a handle may be separately mounted on the main body 20 , or an angle adjustment bracket 100 to be described later may be used as a handle.

In addition, for efficient thermal insulation treatment against the heat generated by the lighting 30 or the ballast, the main body 20 has a structure in which two housings are assembled, specifically, a first housing 21 of a cylindrical shape adjacent to the lighting 30 and a second It is also possible to consist of a second housing 22 similar to a rectangular parallelepiped coupled to the rear surface of the first housing 21 .

The lighting 30 is mounted on the front of the main body 20 to provide a function of illuminating the illumination light, and various well-known lighting 30 can be applied. In particular, it is preferable that the lighting device of the present invention is made of a high-voltage discharge lamp to be used in an environment requiring high illumination, such as a night sports game or a search light.

Here, the 'front side of the main body 20' has a shape close to a cylinder in FIG. 1, and refers to an upper surface that looks at the front from the cylinder, that is, the side on which the illumination light is irradiated. Correspondingly, one surface of the opposite body becomes the 'rear surface of the main body 20', and the circumferential surface between the front and rear surfaces of the main body 20 is the outer peripheral surface of the main body 20 or the 'side surface of the main body 20' define it as

These lights 30 are preferably mounted in plurality in order to provide excellent illumination to the dimming area. As mentioned above, a specific area (dimming area) to be applied as a spotlight or lighting 30 for a night sports game. In order to be able to efficiently irradiate the illumination light to the body 20, it is not randomly distributed and mounted on the front surface of the main body 20, but is grouped in a plurality for each shade 40 (for example, a group consisting of a plurality of LEDs). It also consists of a plurality of pieces together with the nagad (40).

The cap assembly of the present invention consists of the above-mentioned inner cap 40 and outer cap 50.

The inner shade 40 takes a structure protruding toward the front direction of the main body 20 which is the irradiation direction of the illumination light while surrounding the peripheral portion of the illumination 30 , that is, the illumination 30 .

In addition, the outer shade 50 is a structure protruding toward the front side of the body 20, which is also the irradiation direction of the illumination light while surrounding the front peripheral portion of the main body 20, that is, the front of the main body 20.

The inner shade 40 and the outer shade 50 are each formed in a well-known truncated cone shape, thereby assisting in efficiently dispersing the illumination light irradiated from the illumination 30 .

Referring to FIG. 1 , it can be seen that the inner shade 40 is arranged in plurality at equal intervals and at equal angles to form an equilateral triangle, that is, an angle of 120 degrees when the front of the main body 20 is viewed from the front. Thereby, it is possible to more efficiently irradiate the illumination light with high illuminance to the dimming area. The plurality of nae shades 40 are also not necessarily limited to the structure shown in FIG. 1 , and various designs are possible, such as being arranged in four at an angle of 90 degrees or in six at an angle of 60 degrees.

In particular, the above-described inner shade 40 is assembled with a combination of a plurality of assembly pieces 42 to present a structure capable of maximizing the dimming function of the lighting 30 , which will be described later along with subsequent drawings.

The outer shade 50 serves to protect the lighting 30 from natural factors such as external shocks or rain and wind.

Although not shown in the drawing, the controller is accommodated in the internal space of the main body 20 or is electrically connected to the main body 20 so that the power supply and control unit, as well as a specific light 30 among several lights 30, will not be damaged or operated. It is possible to include a ballast that can turn on a separate light 30 when this. That is, the ballast may be connected to each of the lights 30 made of a plurality of lights to control each of the lights 30 .

The angle adjustment bracket 100 of the present invention is a structure formed in a U-shape as a result of extending from both sides of the side of the main body 20 (specifically, the first housing 21) and then connecting two extension ends.

In more detail, the angle adjustment bracket 100 takes the same structure as '∩' when viewed from the front when the lighting 30 is viewed from the front, as can be seen by analogy with FIG. 1 .

The angle adjustment bracket 100 specifically includes a pair of extension parts 110 and a connection part 120 .

The pair of extensions 110 is a unit body as rotatably extended in the front-rear direction of the lighting 30 on each side of the main body 20 via the pair of first hinges 101, It means that the unit body is extended in a total of two from each of the left and right sides of the main body 20 .

At this time, the 'front-back direction of the lighting' means that a pair of extension parts 110 stand on the left and right sides of the main body 20 as shown in figure 11 in the front reference of the lighting 30, and then the first hinge 101 Means a direction in which the light 30 rotates toward the front or rear side via the , and this may be defined as a 'vertical direction'.

The first hinge 101 has the same configuration as a known hinge shaft or a hinge rod rotatably fastened to the indentation holes recessed in both sides of the left and right sides of the main body 20 .

Specifically, the first hinge 101 is fastened to a hinge hole penetrated in each of the pair of extensions 110, and then a known fastener such as a nut is also mounted, so that the extension 110 is the first The extension part 110 is coupled to the body 20 via the first hinge 101 so that the extension part 110 can rotate based on the first hinge 101 without being separated from the hinge 101 . can do.

The connection part 120 is a unit body connecting the ends of the above-described two extension parts 110 in a state in which at least one fastening hole 121 is penetrated in the central part or other parts of the entire extended length.

In this case, the fastening hole 121 is a space in which a fastener such as a bolt or a link provided for the lighting device of the present invention to be mounted on a mounting object such as a wall or a structure is accommodated.

That is, after the fastener is fastened to the fastening hole 121 and then fixed to the mounting target having the coupling hole (not shown), the lighting device of the present invention may be fixedly coupled to the mounting target as a result.

A stopper such as a tooth is formed on the outer circumferential surface of the fastener fixed to the mounting target at regular intervals along the periphery, and a plurality of accommodation grooves capable of accommodating the tooth is formed on the inner circumferential surface of the fastening hole 121 in response thereto. It is formed so that it is possible to adjust the angle of the lighting device of the present invention, for example, 10, 15, 20 degrees on the mounting target, and then fix it in a specific position.

According to the angle adjustment bracket 100, the lighting device 30 of the present invention is fixed to the mounting target through the fastener fastened to the fastening hole 121 of the connection part 120, based on the first hinge 101. ), the angle adjustment bracket 100 (specifically, a pair of extensions) is rotated in the front and rear direction to convert the fixed angle of the lighting device of the present invention conveniently in various environments and conditions while changing the lighting direction of the lighting 30 or The lighting angle can be varied.

In summary, the functional lighting device of the present invention provides the characteristic of conveniently adjusting the lighting direction or the lighting angle by the angle adjustment bracket 100 mounted on the main body 20 .

Referring back to FIG. 1 , it can be seen that a plurality of heat dissipation holes 130 are formed through the extension part 110 and the connection part 120 at regular intervals along each extension direction.

The heat dissipation hole 130 prevents the angle adjustment bracket 100 from being burned or injured when the angle adjustment bracket 100 is formed at a position not far from the lighting 30 and the operator holds the angle adjustment bracket 100 by hand. In other words, the heat dissipation hole 130 radiates this heat to the outside when the heat of the lighting 30 is transferred to the angle adjustment bracket 100, and the surface of the angle adjustment bracket 100 is at an unnecessary temperature or higher. It performs a heat dissipation function to prevent it from rising.

2 is a conceptual diagram illustrating a state in which the body is rotated by the angle adjustment bracket and the auxiliary angle adjustment bracket in FIG. 1 , and FIG. 3 is a conceptual diagram illustrating FIG. 2 from another angle.

As can be seen from FIGS. 2 and 3 , the lighting device of the present invention may include an auxiliary angle adjustment bracket 200 that is an additional bracket in addition to the angle adjustment bracket 100 described above.

The auxiliary angle adjustment bracket 200 is mounted via the above-described angle adjustment bracket 100 to provide a function of rotating the lighting device of the present invention in a separate direction as well as in the front and rear directions of the lighting 30, It consists of a plate-like structure like a thin disk.

First, the second hinge 201 is coupled to the fastening hole 121 of the connection part 120 in the angle adjustment bracket 100 .

The second hinge 201 is a structure such as a shaft or bar that is rotatably coupled to the fastening hole 121 , and has the same or similar structure to the first hinge 101 described above.

Based on this, the auxiliary angle adjustment bracket 200 is coupled to one side of the angle adjustment bracket 100 , specifically, to the fastening hole 121 of the connection part 120 , and more specifically to the second hinge 201 . It refers to a plate-shaped body rotatably coupled to the connection part in clockwise and counterclockwise directions based on the surface of the connection part 120 in a state having a coupling hole (specified below).

Here, 'rotating clockwise and counterclockwise based on the surface of the connection part 120' means the rotation direction of the auxiliary angle adjustment bracket 200 shown in FIG. 1, which is referred to as a 'horizontal direction'. can be defined

That is, through the angle adjustment bracket 100 and the auxiliary angle adjustment bracket 200 of the present invention, it is possible to rotate in two directions: a vertical direction and a horizontal direction.

In addition, since the fastener for coupling with the mounting target is originally fastened to the fastening hole 121 of the connection part 120, the second hinge 201 is coupled to the fastening hole 121 as described above, so the mounting target It is necessary to provide a separate fixing means to the auxiliary angle adjustment bracket 200 for fixing with the.

To this end, the second hinge 201 is coupled to the lower part (lower part) of the coupling hole of the auxiliary angle adjustment bracket 200, and the upper part (upper part) remaining after the second hinge 201 is coupled is left as an empty space. Through this space, fasteners for coupling with the mounting object can be fastened. In this case, a screw thread is formed on the upper inner circumferential surface of the coupling hole, and correspondingly, a screw thread is also formed on the outer circumferential surface of the fastener. environment can be provided.

Of course, in the structure provided with the above-described screw thread, if the lighting device of the present invention rotates in only one direction, the lighting device may be detached or bound to the mounting target. It needs to be rotated counterclockwise.

According to this auxiliary angle adjustment bracket 200, it is possible to adjust the lighting angle in the up and down (vertical) direction as well as in the left and right (horizontal) directions by the angle adjustment bracket 100 described above, so that a more colorful lighting angle adjustment environment It provides the properties that can be built.

4 is a conceptual view showing the structure of the coupling plate mounted on the auxiliary angle adjustment bracket.

Referring to FIG. 4 , it can be seen that the auxiliary angle adjustment bracket 200 is made of a combination of the base body 210 , the rotating plate 220 , and the socket 230 .

The base body 210 is a structure in which a through hole 211 is penetrated at a position corresponding to the fastening hole 121 of the connection part 120 in the center in a state in which it extends for a certain length in the same direction as the extension direction of the connection part 120, It is a plate-shaped body that is fixedly coupled to the fixing holes formed on both sides through holes and bolts formed separately in the connection part 120 .

The rotating plate 220 is a plate-shaped body rotatably seated or coupled to the central portion of the base body 210 , and the first coupling hole 221 passes through at a position corresponding to the through hole 211 of the base body 210 . has been

At this time, the base body 210 is formed with a recessed space that can accommodate the rotating plate 220 can accommodate the rotating plate 220, otherwise the rotating plate 220 directly on the surface of the base body 210 is It may be seated while touching.

The circumference of the rotating plate 220 in a state in which a plurality of first coupling protrusions 222 protrude radially around the first coupling hole 221 around the first coupling hole 221 of the rotating plate 220 . extended to each part.

Finally, the socket 230 is seated or coupled to the surface (upper surface) of the rotating plate 220 in a state where the second coupling hole 231 is penetrated in the central portion corresponding to the first coupling hole 221 . It is a plate body.

The socket 230 also has a second coupling protrusion 232 extending radially around the second coupling hole 231, and an inner ring 233 formed around the second coupling hole 231 as shown in the figure. ) through the second coupling protrusion 232 may be formed to extend.

At this time, the second coupling protrusion 232 is formed in a smaller number than the first coupling protrusion 222 and further, the width (left and right width based on the horizontal plane) is wider than the first coupling protrusion 222 .

According to this structure, the second hinge 201 passes from the fastening hole 121 of the connection part 120 to the through hole 211 of the base body 210 and the first coupling hole 221 of the rotating plate 220 to the socket. It extends to the second coupling hole 231 of the 230 . In other words, in a state in which the base body 210 , the rotation plate 220 , and the socket 230 are coupled to the second hinge 201 , the rotation plate 220 excluding the base body 210 fixedly coupled to the connector 120 . ) and the socket 230 are rotatable based on the second hinge 201 .

At this time, the first and second coupling protrusions 222 and 232 of the rotating plate 220 and the socket 230 may be tooth-like coupled along the space therebetween, and the number and width of the first and second coupling protrusions 222 and 232 are different. Therefore, instead of maintaining a perfect tooth-like coupling, they are momentarily misaligned with each other according to the rotational acceleration of the rotating plate 220 and the socket 230 .

Here, when the rotating plate 220 and the socket 230 are in perfect contact, the above-described action does not occur, so a spotter such as a nut is placed at the upper and lower lower points higher than the overall height of the rotating plate 220 and the socket 230 . When the lighting device of the present invention rotates by fixed coupling, the rotation plate 220 and the socket 230 can be spaced apart from each other, and the above-described operation can be implemented.

In addition, as can be seen from the drawings, it is also possible that the second hinge 201 is provided with a hollow in the state in which it is opened in the direction of the mounting target, and a fastener for fixing to the mounting target is fastened in the hollow.

For this reason, when the lighting device of the present invention is rotated, a deceleration effect can be seen, and as a result, the lighting device can be rotated stably without being twisted to the left or right or flowing excessively.

In addition, of course, the socket 230 may serve as a kind of cushioning and anti-wear packing between the mounting target and the base body 210 and the rotating plate 220 .

By this configuration and action, the auxiliary angle adjustment bracket 200 provides a characteristic that can ensure more stable rotation when the lighting device of the present invention rotates clockwise / counterclockwise.

Figure 5 is a perspective view showing the separation structure of the naegat of the present invention, Figure 6 is a side view showing a state in which the assembly piece is coupled.

As can be seen from FIGS. 5 and 6 , the inner shade 40 of the present invention is not made of a single unit, but a combination of a plurality of assembly pieces 42 .

Specifically, the inner shade 40 extends along the peripheral portion of the lighting 30, that is, the ring 41 surrounding the lighting 30, and the ring 41 along the perimeter of the ring 41 to be radially overlapped with each other and extended. It includes an assembly piece (42).

At this time, coupling protrusions 42a and slits 42b are formed on both sides of the assembling piece 42 based on the extending direction of the assembling piece 42, so that they can be fixedly coupled to each other while performing uneven coupling with the adjacent assembling piece 42. In addition, a plurality of engaging slits 41a are formed through the upper portion (end in the ring direction) of the assembly piece 42 at regular intervals along the circumferential direction of the ring 41 in correspondence with the engaging projections 42a. It is possible to be firmly fixedly coupled to the ring 41 so as not to be separated to the outside.

By this structure, it is possible to adjust the range in which the lighting 30 is diffused while partially adjusting the inclination of the assembly piece 42 rather than the inner shade 40 made of a single body, as well as convenient and convenient assembly piece 42 by a relatively simple structure. ) can be provided with the ability to assemble.

As another embodiment, it is possible that the coating layer is laminated on the inner surface facing the lighting 30 in the assembly piece 42 . At this time, the inner surface of the assembly piece 42 may be first coated with a light reflective layer (ie, a reflective layer made of a known material that reflects light without absorbing light) capable of reinforcing the smooth reflection of illumination light.

The coating layer has high hardness and transparency to prevent the inner surface (for example, the light reflective layer coated on the inner surface) of the inner shade 40 from being peeled off by an external force, thereby inhibiting the reflection function of the illumination light or contamination with external foreign substances. As to provide a protective role of the inner side of the shade 40, it is made to be transparent to translucent so as not to impair the function of reflecting illumination light on the inner surface of the shade 40.

More specifically, the coating layer contains DMDS (Dimethyldichlorosilane), which is a precursor for producing PCS (Polycarbosilane) with hardness and transparency, and PPCS (Poly phenylcarbosilane) that has more carbon than PCS to reinforce the mechanical properties of the coating layer. do.

By including such a composition in the coating layer, the coating layer secures excellent hardness and transparency to prevent damage to the inner surface of the inner cap 40 as well as foreign substances easily staining the inner surface of the inner cap 40 easily. .
As described so far, although the configuration and operation of the functional lighting device having an improved angle adjustment function according to the present invention have been expressed in the above description and drawings, this is merely an example and the spirit of the present invention is not limited to the above description and drawings is not limited thereto, and various changes and modifications are possible without departing from the technical spirit of the present invention.
