[0010] A lighting fixture according to an embodiment of this disclosure will be described in detail with reference to the drawings. However, the figures described in the embodiments below are schematic diagrams, and the ratios of the size and thickness of each component do not necessarily reflect the actual dimensional ratios. The configuration described in the following embodiments is merely one example of this disclosure. This disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of this disclosure can be achieved.

[0011] (1) Overview The lighting fixture A1 according to this embodiment comprises a light source unit 2 (light source section) that emits illumination light, a fixture body 1 that supports the light source unit 2, a frame 3 that has a window 300 through which the illumination light passes and is attached to the fixture body 1, and an arm 4 that rotatably holds the frame 3 (see Figures 1-3).

[0012] In the embodiment of the lighting fixture A1, the arm 4 is attached to the frame 3 rather than the fixture body 1. Therefore, since the lighting fixture A1 in the embodiment does not require a part (for example, a screw hole) for attaching the arm 4 to the fixture body 1, the fixture body 1 can be formed from a metal plate.

[0013] As a result, the lighting fixture A1 according to this embodiment can be made lighter than the conventional example in which the fixture body is formed from die-cast aluminum. Furthermore, in the lighting fixture A1 according to this embodiment, for example, if the fixture body 1 is formed by processing a sheet of pure aluminum, both weight reduction and improved heat dissipation can be achieved.

[0014] (2) Details The lighting fixture A1 according to this embodiment (hereinafter referred to as lighting fixture A1) is used, for example, to illuminate outdoor parking lots, grounds, etc. In the following description, unless otherwise specified, the up and down, front and back, and left and right directions indicated by arrows in Figure 1 are defined as the up and down, front and back, and left and right directions of lighting fixture A1.

[0015] The lighting fixture A1 includes a fixture main body 1, a light source unit 2, a frame 3, an arm 4, a seal member 5, a power supply unit 6, a power cable 7, a lens unit B1, etc.

[0016] (2-1) Fixture main body The fixture main body 1 has a housing portion 10 that houses the power supply unit 6, and a flange portion 11 that supports the light source unit 2 and the lens unit B1 (see FIGS. 2 and 3).

[0017] The housing portion 10 is formed in a rectangular box shape with an open front (see FIG. 3). The power supply unit 6 is attached to the inner bottom surface of the housing portion 10. The power supply unit 6 includes, for example, a switching power supply circuit and converts the AC power supplied from the power system through the power cable 7 into DC power. The power cable 7 is drawn out to the rear of the housing portion 10 through a hole penetrating the bottom of the housing portion 10 (see FIGS. 2, 5, and 6). However, the power cable 7 is fixed to the outer bottom surface of the housing portion 10 by a cable ground 14 (see FIG. 2). The cable ground 14 fixes the power cable 7 to the fixture main body 1 and seals the gap between the power cable 7 and the hole in the bottom of the housing portion 10.

[0018] The flange portion 11 is formed in a rectangular frame shape when viewed from the front-rear direction and protrudes outwardly over the entire circumference from the front end (open end) of the housing portion 10. A protruding wall 13 that protrudes forward over the entire circumference is provided at the outer peripheral end of the flange portion 11 (see FIG. 3). Also, circular insertion holes 111 are provided at the four corners and the centers of the four sides of the flange portion 11, respectively. Further, cylindrical internal thread portions 112 are provided at both ends of the four sides on the inner peripheral edge of the flange portion 11 (see FIGS. 2 and 3).

[0019] The housing portion 10, the flange portion 11, and the protruding wall 13 that constitute the fixture main body 1 are integrally formed by drawing and bending a metal plate (for example, a plate made of pure aluminum).

[0020] (2-2) Light source unit The light source unit 2 includes an LED module 20 and a mounting plate 21 to which the LED module 20 is attached (see Figure 3).

[0021] The LED module 20 comprises a rectangular substrate 201 and a plurality of LEDs 200 mounted on the front surface of the substrate 201. Each of the plurality of LEDs 200 is a packaged white LED for illumination. The substrate 201 is, for example, a metal base substrate based on an aluminum plate. Because the substrate 201 is a metal base substrate, the heat generated by the plurality of LEDs 200 can be efficiently dissipated. The plurality of LEDs 200 are mounted on the surface of the substrate 201 in multiple rows along the vertical (up and down) and horizontal (left and right) directions, at approximately equal intervals.

[0022] The mounting plate 21 is formed, for example, from an aluminum plate into a rectangular flat plate shape. The vertical (top and bottom) and horizontal (left and right) lengths of the mounting plate 21 are longer than the vertical and horizontal lengths of the substrate 201 of the LED module 20. Therefore, when the LED module 20 is screwed to the front of the mounting plate 21, the peripheral portion of the mounting plate 21 protrudes around the LED module 20 (see Figure 3). In the peripheral portion of the mounting plate 21 that protrudes around the LED module 20, one insertion hole is provided at both the left and right ends on the upper and lower sides.

[0023] The light source unit 2 is secured to the flange portion 11 by screwing mounting screws 22, one screw each, into the four internal threaded portions 112 of the flange portion 11, which are then screwed into the four internal threaded portions 112 of the flange portion 11 (see Figure 8).

[0024] (2-3) slots The frame 3 comprises a frame body 30, a pair of mounting parts 31, and a projection 32. The frame body 30, the pair of mounting parts 31, and the projection 32 that constitute the frame 3 are integrally formed by punching and bending a metal plate (for example, a sheet of pure aluminum).

[0025] The frame body 30 includes an upper plate 301 which forms the upper window frame, a lower plate 302 which forms the lower window frame, a left plate 303 which forms the left window frame, and a right plate 304 which forms the right window frame. The upper plate 301 and the lower plate 302 are formed in the shape of narrow strips and are arranged so that their thickness is aligned with the vertical direction. The left plate 303 and the right plate 304 are also formed in the shape of narrow strips and are arranged so that their thickness is aligned with the horizontal direction. The left and right ends of the upper plate 301 are connected to the upper ends of the left plate 303 and the right plate 304, respectively, and the left and right ends of the lower plate 302 are connected to the lower ends of the left plate 303 and the right plate 304, respectively. Thus, the frame body 30 has a window 300 which uses the upper plate 301, the lower plate 302, the left plate 303, and the right plate 304 as window frames. Furthermore, one concealed portion 33 is formed at each end of the upper plate 301 in the longitudinal direction (left-right direction) (see Figure 7). These two concealed portions 33 are formed in a trapezoidal shape and protrude from the rear ends of both ends of the upper plate 301 in the longitudinal direction.

[0026] The projection 32 is formed in a rectangular frame shape when viewed from the front or back direction, and protrudes toward the window 300 from the front ends of the upper plate 301, lower plate 302, left side plate 303, and right side plate 304. One through hole 320 is provided at each of the four corners of the projection 32 and at the center of the longitudinal direction of each of the four sides (see Figure 3).

[0027] The pair of mounting portions 31 are formed in a trapezoidal shape and are integrally formed with the frame body 30 so as to protrude rearward from the rear ends of the lower parts (the lower part from the center in the vertical direction) of the left plate 303 and the right plate 304, respectively (see Figures 3 and 5). One nut 81 is fixed to the lower part of each of the pair of mounting portions 31 (see Figures 3 and 6). Each nut 81 is a crimp nut (also called a piercing nut or rivet nut) and is fixed by crimping into a through hole provided in the mounting portion 31.

[0028] (2-4) Arm The arm 4 has a fixed portion 40 and a pair of arm portions 41. The fixed portion 40 and the pair of arm portions 41 are integrally formed by punching and bending a metal plate (for example, a sheet of pure aluminum).

[0029] The fixing part 40 is formed in the shape of a trapezoidal plate (see Figure 7). The fixing part 40 is provided with three circular mounting holes 400 arranged in a row. For example, one anchor bolt embedded in a concrete base or the like is inserted through each of these three mounting holes 400, and a nut is tightened on each anchor bolt to fix the fixing part 40 to the object to be fixed (base).

[0030] The pair of arm portions 41 are formed in a roughly L-shape and protrude diagonally upward and backward from the pair of slanted sides (sides corresponding to the legs of a trapezoid) of the fixing portion 40. Each of the pair of arm portions 41 is provided with one through hole 410 at its tip (see Figure 3).

[0031] The arm 4 is attached to the frame 3 with two bolts 80. Specifically, the bolts 80, which are inserted through the insertion holes 410 of each arm section 41, are screwed into nuts 81 fixed to each mounting section 31 of the frame 3, thereby rotatably attaching each arm section 41 to each mounting section 31 (see Figures 4-7).

[0032] (2-5) Lens Unit The lens unit B1 comprises a unit body 90, a peripheral portion 91, and a plurality of lenses 92 (see Figure 3). The unit body 90, the peripheral portion 91, and the plurality of lenses 92 are integrally formed from a light-transmitting synthetic resin material (for example, polycarbonate resin or acrylic resin).

[0033] The unit body 90 is formed in the shape of a square tray. The outer bottom surface (front) of the unit body 90 is flat, and multiple lenses 92 are formed on the inner bottom surface of the unit body 90. The multiple lenses 92 correspond one-to-one with the multiple LEDs 200 of the LED module 20. In other words, the light distribution of the light emitted from each LED 200 is controlled by each lens 92 that corresponds one-to-one with each LED 200.

[0034] The peripheral portion 91 protrudes from the periphery of the unit body 90 all around. One semicircular screw insertion groove 910 is provided at the center in the left-right direction at both the upper and lower ends of the peripheral portion 91, and at the center in the vertical direction at both the left and right ends of the peripheral portion 91 (see Figure 3).

[0035] (2-6) Sealing member The sealing member 5 is formed from silicone rubber and has a rectangular frame shape when viewed from the front or back direction (see Figure 3). However, the sealing member 5 may be formed from an elastic material other than silicone rubber.

[0036] The sealing member 5 has a first sealing portion 51 and a second sealing portion 52 (see Figure 8). Both the first sealing portion 51 and the second sealing portion 52 are formed in the shape of a rectangular frame. The outer circumferential ends of the first sealing portion 51 and the outer circumferential ends of the second sealing portion 52 are connected by a connecting portion 53 which is also formed in the shape of a rectangular frame. In other words, a groove 54 is formed around the entire circumference of the sealing member 5, surrounded by the first sealing portion 51, the second sealing portion 52, and the connecting portion 53, and opening to the inner circumferential surface (see Figure 8).

[0037] Two ribs 55 are formed around the entire circumference of the front and rear surfaces of the first seal portion 51 (see Figure 8). Similarly, two ribs 55 are formed around the entire circumference of the front and rear surfaces of the second seal portion 52. In addition, one screw insertion groove 56 is provided at each of the vertical and horizontal ends and in the center of the seal member 5 (see Figure 3).

[0038] (2-7) Assembly of lighting fixtures Next, we will explain the assembly procedure for lighting fixture A1. However, the assembly procedure described below is just one example, and the order of some steps may be changed.

[0039] First, the worker performing the assembly attaches the power unit 6 to the inner bottom surface of the housing section 10 of the main body of the device 1, and then electrically connects the power cable 7 to the power unit 6. Then, the worker pulls the power cable 7 out of the housing section 10 through a hole that penetrates the bottom of the housing section 10, and secures the power cable 7 to the outer bottom surface of the housing section 10 with a cable gland 14.

[0040] Next, the worker inserts one mounting screw 22 into each of the four insertion holes provided in the mounting plate 21 of the light source unit 2, and then screws these four mounting screws 22 into each of the four female threaded portions 112 of the flange portion 11, thereby screwing the light source unit 2 to the flange portion 11. Before screwing the light source unit 2 to the flange portion 11, the worker electrically connects the output wires drawn from the power supply unit 6 to the connector mounted on the circuit board 201 of the LED module 20.

[0041] Next, the worker inserts the peripheral edge 91 into the groove 54 of the sealing member 5 and attaches the sealing member 5 to the peripheral edge 91 of the unit body 90. Then, the worker places the lens unit B1 with the sealing member 5 attached onto the front of the flange portion 11, and then places the frame 3 over the sealing member 5 from the front.

[0042] Then, the worker inserts one mounting bolt 34 from the front into each of the eight through-holes 320 in the projection 32 and the eight through-holes 111 in the flange portion 11. The worker then fastens two mounting nuts 35 to each mounting bolt 34 inserted into each through-hole 111 of the flange portion 11 to fix the frame 3 to the flange portion 11 of the fixture body 1 (see Figure 8).

[0043] Finally, the worker attaches the arms 4 to the frame 3 by inserting one bolt 80 into each of the insertion holes 410 of the pair of arm sections 41 and screwing one bolt 80 into each of the nuts 81 fixed to the pair of mounting sections 31.

[0044] The assembly of lighting fixture A1 is completed by following the steps above.

[0045] (3) Advantages of the embodiment As described above, lighting fixture A1 has an arm 4 attached to a frame 3 which is attached to the fixture body 1. Therefore, compared to conventional examples where the arm is attached to the fixture body, lighting fixture A1 does not require holes in the fixture body for inserting bolts to attach the arm. As a result, lighting fixture A1 can be made by processing a metal plate to form the fixture body 1 instead of using a die-cast fixture body, thus reducing the weight of the fixture body 1. In addition, by using a pure aluminum plate to form the metal plate that makes up the fixture body 1, lighting fixture A1 can achieve improved heat dissipation compared to a fixture body made of aluminum alloy. Furthermore, with the weight reduction of the fixture body 1, the thickness of the metal plate that forms the arm 4 can be reduced (thinned down), which reduces manufacturing costs by reducing material costs.

[0046] Furthermore, in lighting fixture A1, the tips of the pair of arm portions 41 of the arm 4 are rotatably attached to the pair of mounting portions 31 provided on the frame body 30 of the frame 3, thereby improving the strength of the joint between the frame 3 and the arm 4. Moreover, in lighting fixture A1, the width dimension of the pair of mounting portions 31 is larger than that of the frame body 30 other than the pair of mounting portions 31, so that the size of the frame 3 can be suppressed while further improving the strength of the joint between the frame 3 and the arm 4.

[0047] In the lighting fixture A1, the shaft of the bolt 80 connecting the frame 3 and the flange portion 11 of the fixture body 1 protrudes from the rear surface of the flange portion 11 (see Figure 2). Therefore, lighting fixture A1 is provided with concealed portions 33 that protrude parallel to the fixture body 1 from both ends of the upper plate 301 of the frame body 30, and the shaft of the bolt 80 protruding from the rear surface of the flange portion 11 is concealed by the concealed portions 33 (see Figure 7). Thus, lighting fixture A1 can improve its appearance by concealing the bolt 80 with the concealed portions 33.

[0048] Incidentally, when lighting fixture A1 is installed with the illumination direction facing upward, the mounting bolts 34 and mounting nuts 35 may loosen, potentially causing part or all of the fixture body 1 to detach from the frame 3. However, in lighting fixture A1, a portion of the fastening members (bolts 80 and nuts 81) that fasten the frame 3 and the arm 4 are hidden by the fixture body 1 (flange portion 11) when viewed from the rear (direction facing the window 300) (see Figure 6). Therefore, lighting fixture A1 can prevent the fixture body 1 from falling by having it hit the bolts 80 and nuts 81 when it detaches from the frame 3.

[0049] Furthermore, the lighting fixture A1 is further equipped with a light-transmitting panel (lens unit B1) that is transparent to illumination light and positioned in the window 300 to protect the light source unit 2. In this embodiment, the light-transmitting panel also functions as a light distribution control member that controls the light distribution of the LED module 20. In other words, since the lighting fixture A1 incorporates the light distribution control member and the protection function for the light source unit 2 into a single component (lens unit B1), the number of parts can be reduced, thereby improving the workability of the assembly process. In the lighting fixture A1, the peripheral portion of the mounting plate 21 and the peripheral portion 91 of the lens unit B1 are sandwiched between the projection 32 and the flange portion 11 (see Figure 8). Therefore, the lighting fixture A1 can be attached to the fixture body 1 together with the frame 3, thereby improving the workability of the assembly process.

[0050] Furthermore, lighting fixture A1 has a housing section 10 in the fixture body 1, and the power supply unit 6 that supplies power to the light source unit 2 is housed in the housing section 10 (see Figure 3). Therefore, lighting fixture A1 can reduce the installation space compared to when the power supply unit 6 is installed outside the fixture body 1.
