However, in the case of the existing floodlights and floodlights, since they do not have additional heat dissipation measures other than the lighting body and heat dissipation fins made of a metal material with excellent heat dissipation efficiency, high-temperature heat generation due to high brightness is still a problem, and the lighting Most of the converters have a structure in which the main body is fixed in close contact with each other, so the lighting body has a lower heat dissipation efficiency due to the converter, and the converter has a lower heat dissipation efficiency due to the lighting body. The main body and the converter have negative ends that act as an obstacle to each other.

In addition, the existing light emitter has a single light source, that is, an LED substrate, and designs a light distribution curve with the shape of the above LED substrate and lighting body. Inevitably, it is impossible to obtain illumination and uniformity in the desired direction through the change of the irradiation angle of the light projector to the lighting body.

Accordingly, since it is impossible to change the light distribution curve of the projector itself, it is necessary to secure the illuminance and uniformity for the lighting object or lighting space through angle adjustment of the lighting body with respect to the installation bracket, but the irradiation angle in the desired direction does not appear. Otherwise, if sufficient illuminance and uniformity cannot be secured, it is extremely poor in terms of lighting design and efficiency in consideration of the light distribution curve and uniformity, such as having to additionally install the floodlight or change the installation location of the floodlight.

As shown, in the dual-type light projector according to the present invention, both ends of the installation bracket 200 formed by bending a metal plate in the shape of a "C" at both ends of the fastening member 100 having a rectangular shape on a plane are hinged. It is coupled so that the angle of the fastening member 100 is adjusted from the installation bracket 200, and a pair of lighting bodies 300 and 300 ′ are provided at both ends of the fastening member 100 in one direction. Each is hinged so as to be individually adjusted from the angle.

In addition, a converter 400 for supplying power to the lighting body 300 and 300' is mounted on the upper side of the installation bracket 200, and the installation bracket 200 is fixed or suspended from the ceiling. In a state in which the installation bracket 200 is fixedly installed on the wall or floor, angle adjustment of the pair of lighting bodies 300 and 300 ′ through the angle adjustment of the fastening member 100 with respect to the installation bracket 200 is performed. Simultaneously, or as the respective lighting bodies 300 and 300 ′ are individually angled from the fastening member 100 , variable control of the light distribution curve of the projector itself or the change of the irradiation angle can be made.

Therefore, the convenience of lighting design for the desired lighting object or space is further improved due to the adjustment of the irradiation angle of the emitter and the variable setting of the light distribution curve, as well as the improvement of uniformity and the most efficient and reasonable lighting with the minimum emitter form can be implemented.

Here, the pair of lighting bodies 300 and 300' as described above are formed in a semi-circular shape on a plane, and when each hinged to the fastening member 100 in opposite directions, the pair of lighting bodies 300, 300' ) is configured to form a circle on a plane, and since a pair of lighting bodies 300 and 300 ′ form a circle by a combination, the appearance of the projector as a single entity is produced as a whole as in the prior art, and the conventional projector The light emitter of the present invention, which has the same appearance as that of the present invention, is not only able to adjust the overall angle with respect to the lighting body 300, 300', but also adjusts the individual angle of each lighting body 300, 300' to distribute light that is impossible with the existing projector. The variable setting of the curve is possible, as well as the effect of improving the evenness using this.

However, in the case of the lighting body 300, 300' as described above, it is not limited to just a semi-circle, but can be manufactured in various shapes such as a square, a rectangle, or an oval if necessary. It will be understood that the lighting body 300, 300' will have a shape most similar to that of a conventional circular projector, and thus it is described as a preferred embodiment.

Next, looking at the assembly structure of the fastening member 100 with respect to the installation bracket 200 and the mutual angle adjustment means using the same, both ends of the installation bracket 200 as described above have a through-screw shaft hole 201 as the center. A semicircular flow hole 202 of A fastening screw hole 102 is formed, and a hinge bolt 210 coupled to the fastening screw hole 101 through the screw shaft hole 201 and a fixing bolt to the fastening screw hole 102 through the flow hole 202 (211) is combined.

Accordingly, the rotation of the fastening member 100 from the installation bracket 200 with the hinge bolt 210 as the central axis and the angle adjustment of the lighting body 300 and 300 ′ are made accordingly. When it is necessary to adjust the angle of the fastening member 100, loosen the fixing bolt 211 from the tightening screw hole 102 to a loose state, and then rotate the fastening member 100 in a desired direction to adjust the angle. In such a state that the fixing bolt 211 is tightened and inserted into the tightening screw hole 102, the fixing bolt 211 closely fixes the side end of the installation bracket 200 to the fastening member 100. Since it plays a role, as a result, the fastening member 100 of the angle-adjusted state can maintain a fixed state that does not flow from the installation bracket 200 .

Accordingly, the fastening member 100 can be freely adjusted in angle from the installation bracket 200 within the range of the flow hole 202 and fixed in the adjusted state. Through this, a simple change of the lighting irradiation angle can be made in the fixed installation state of the floodlight.

Next, in the case of the fastening member 100 as described above, as shown in FIG. 5 , on the upper surface, there are lattice-shaped heat dissipation fins 103 and 103 ′, upwardly protruding support ribs 104 and 104 ′, and vertical penetration slit fastening holes. 105 and 105' are formed, respectively, and the support ribs 104 and 104' protrude higher than the tip of the heat dissipation fins 103 and 103' to be in close contact with the bottom of the converter 400, The slit fastening holes 105 and 105' are configured to be vertically penetrated on the heat dissipation fins 103 and 103'.

Therefore, the converter 400 is mounted on the fastening member 100 as described above and coupled by the fastening bolts inserted and fixed into the slit fastening holes 105 and 105 ′ (symbols in the drawings are omitted). Since the support ribs 104, 104' from the upper surface of 100 are fixed upwardly spaced apart, an excellent heat dissipation action can be expected from the entire fastening member 100 including the heat dissipation fins 103 and 103'. In addition, since the converter 400 itself does not form a sealed or close-contact surface in all directions, the heat dissipation action of the converter 400 can also be greatly improved.

In addition, each of the hinge shaft portions 110 and 110 ′ having a shaft hole 111 are formed on both sides of the fastening member 100 in one direction as described above, and on the upper side of the lighting body 300 and 300 ′, the The shaft is inserted into the shaft bearing hole 111 and the shaft insertion hole 312 by forming a fastening guide 310 having a shaft coupling part 311 having a shaft insertion hole 312 corresponding to the shaft bearing hole 111, A pair of lighting bodies 300 for the fastening member 100 by the bolts 320 and 320' and the fastening nuts 321 and 321' coupled to the shaft bolts 320 and 320' ( 300') is configured so that each individual angle adjustment and fixation are made.

Therefore, as shown in Fig. 6, the shaft hole 111 formed in the hinge shaft part 110, 110' and the shaft insertion hole formed in the shaft coupling part 311 of the lighting body 300, 300' ( After inserting the shaft bolts 320 and 320' into 312), tightening nuts 321 and 321 are attached to the ends of the shaft bolts 320 and 320' that protrude through the hinge shaft portions 110 and 110'. '), a pair of lighting bodies 300 and 300' with respect to the fastening member 100 are individually hinged for each adjustable angle.

Accordingly, each lighting body 300, 300' as described above has a coupling structure rotatable about the shaft bolts 320 and 320' as a central axis, and the tightening nuts 321 and 321' It is possible to change the irradiation angle by rotating each lighting body 300, 300 ′ with respect to the fastening member 100 in a loosely coupled state, and the tightening nut 321 ( 321 ) ( When 321') is strongly tightened, the lighting body 300, 300' can continuously maintain the angle-adjusted state from the fastening member 100 by the mutual adhesion fixing force.

At this time, a stopping protrusion 112 is formed on one side of the hinge shaft portions 110 and 110 ′ of the fastening member 100 as described above, and a locking protrusion 313 is formed on one side of the shaft insertion portion 311 of the fastening guide 310 . ), the lighting body 300, 300' in a horizontal state from the fastening member 100 by mutual interference between the locking projections 313 for the stop projection 112 is converted to a vertical state and a horizontal state It may be configured to adjust the angle within the range from to the vertical state.

That is, in the state in which the lighting body 300, 300' is horizontal, the upper one side of the locking protrusion 313 comes into contact with the bottom surface of the stopper 112 and can no longer descend. The locking projection 313 of the fastening guide 310 coupled to the lighting body 300 and 300' by rotating the lighting body 300, 300' upward for angle adjustment is the stopping projection 112. When it reaches a state in which it can no longer be rotated upward in contact with the upper front surface of the lighting body 300, 300', a state in which the angle is adjusted in the vertical direction is produced.

Accordingly, the lighting body 300, 300 'can be adjusted in angle within a range of 90° from a horizontal state to a vertical state. lighting will be produced, and through individual angle adjustment for the lighting body 300, 300 'of both sides, it can be adjusted colorfully so that simultaneous lighting in vertical and horizontal directions as well as lighting in various oblique directions are produced. will be.

Next, the fastening guide 310 may be integrally formed on the upper surface of the lighting body 300, 300', but more preferably, the fastening guide 310 as shown in FIGS. 7 and 8 is provided. It is formed separately from the lighting body 300, 300' so that it can be easily mounted or detached from the upper surface of the lighting body 300, 300', and more preferably, the lighting body 300, 300') It is configured so that the fastening guide 310 is fixed in flow.

That is, on the upper surface of the lighting body 300, 300', position adjustment holes 301 and 301' spaced at regular intervals are repeatedly formed, and the position adjustment hole 301 is formed on the fastening guide 310. Positioning holes of the lighting body 300, 300' with respect to the assembly holes 314 and 314' of the fastening guide 310 by penetrating through the assembly holes 314 and 314' corresponding to the 301'. According to the mutual coupling position between the (301) and (301'), the lighting body (300) (300') is configured to be variable in extension from the fastening member (100).

Therefore, the lighting body 300, 300' is moved and fixed in the outward direction with respect to the fastening guide 310 hinged to the fastening member 100, so that the dual lighting body 300, 300' of both sides is outside. It can be expanded and assembled in the direction, and by this expansion assembly, a change in the light distribution curve and a change in the uniformity can be caused, so that it can be used efficiently in various lighting designs, as well as adjustment of the irradiation angle as described above and the above The best lighting can be produced through one-sided deflection expansion or both-side expansion assembly of the lighting body 300, 300'.

Next, on the upper surface of the lighting body 300, 300' as described above, guide ribs 303 and 303' that are positioned on both sides of the fastening guide 310 along the longitudinal direction of the fastening guide 310 are projected upward. By forming the fastening guide 310 to be easily guided and seated, the flow of the fastening guide 310 along the guide ribs 303 and 303' can be easily made, and these guide ribs 302 ) The position adjustment holes 301 and 301' formed between the 302' are configured to be formed in the assembly bosses 302 and 302' that protrude upward from the upper surface of the lighting body 300, 300'. .

In addition, in the lower surface of the assembly holes 314 and 314' of the fastening guide 310, expansion grooves 315 and 315' through which the tips of the assembly bosses 302 and 302' are inserted are formed to form the lighting body ( When the fastening guide 310 is placed between the guide ribs 303 and 303' of 300 and 300', the assembly bosses 302 and 302' having the positioning holes 301 and 301' Since it will be possible to fix the bolts in the state inserted into the extension grooves 315 and 315', eventually rainwater from the upper surface of the lighting body 300, 300' is the lighting body 300, 300'. It can be prevented from flowing into the interior of the lighting body 300, 300' through the positioning holes 301 and 301' due to the assembling bosses 302, 302' formed at a position higher than the upper surface. An effective waterproof coupling structure can be realized.

At this time, except for the position adjustment holes 301 and 301' of the lighting body 300 and 300', which are bolted to correspond to the assembly holes 312 and 312' of the fastening guide 310, the remaining exposure positions are A waterproof structure for the entire position adjustment hole 301, 301' may be applied by inserting and fixing the waterproof caps 330 and 330' made of a soft elastic material into the adjustment holes 301 and 301'.
