It includes a plurality of intermediate light emitting elements 33 arranged at intervals. The plurality of edge light emitting elements 32 are densely arranged at intervals narrower than the intervals between the plurality of intermediate light emitting elements 33.

Specifically, the first light source module 3a and the second light source module 3b each include a substrate 34 formed in a long rectangular shape and a plurality of light emitting elements 35 mounted on the surface (front surface) of the substrate 34. have Each of the plurality of light emitting elements 35 is an LED (light emitting diode). The plurality of light emitting elements 35 have the same specifications, and the luminous flux changes depending on the magnitude of the current flowing therethrough. The first light source module 3a and the second light source module 3b have a common structure. In this embodiment, the second light source module 3b is obtained by rotating the first light source module 3a by 180 degrees on a vertical plane. Below, the first light source module 3a will be explained in detail.

Four light emitting elements 35a, 35b, 35c, and 35d are mounted in a matrix on the end of the substrate 34 that is closer to the functional component 4 (that is, the left end). The four light emitting elements 35a, 35b, 35c, and 35d constitute a plurality of end light emitting elements 32.

Four light emitting elements 35 are arranged and mounted in a matrix on the end of the substrate 34 that is far from the functional component 4 (that is, the right end). The arrangement of the four light emitting elements 35 is similar to the arrangement of the four light emitting elements 35a, 35b, 35c, and 35d. That is, the first light source module 3 a further includes a second end light emitting section 36 located at the end farthest from the functional component 4 . An intermediate light emitting section 31 is located between the end light emitting section 30 and the second end light emitting section 36 . The second end light emitting section 36 includes four light emitting elements 35 mounted in a matrix on the right end of the substrate 34 . Therefore, the second end light emitting section 36 has a larger luminous flux per unit area than the intermediate light emitting section 31.

A plurality of light emitting elements 35 are mounted on the remaining portion of the substrate 34 excluding the left and right ends so as to be lined up in a row in the left and right direction at regular intervals. The plurality of light emitting elements 35 lined up in a row in the left-right direction constitute a plurality of intermediate light emitting elements 33.

The first light source module 3a further includes an electric circuit 7 shown in FIG. The electric circuit 7 supplies a current flowing through each of the plurality of end light emitting elements 32 (light emitting elements 35a, 35b, 35c, 35d) to one of the plurality of intermediate light emitting elements 33 (the plurality of light emitting elements 35). It is configured to be larger than the current flowing through it.

Specifically, the first light source module 3a includes one first block B1, one second block B2, and a plurality of third blocks B3. The first block B1 is configured by three light emitting elements 35a, 35b, and 35c electrically connected in parallel. The second block B2 is configured such that a light emitting element 35d and three light emitting elements 35 forming the intermediate light emitting element 33 are electrically connected in parallel. Each of the plurality of third blocks B3 has four sets of two light emitting elements 35 electrically connected in series, and the two light emitting elements 35 of these four sets are electrically connected in parallel. It is configured. The first block B1, the second block B2, and the plurality of third blocks B3 are each electrically connected in parallel with a capacitor C1 for suppressing current ripple.

A current of the same magnitude is supplied to the first block B1, the second block B2, and the plurality of third blocks B3 from a regular lighting device described later. For example, assume that a current of 400 mA is supplied from the regular lighting device to the first light source module 3a. At this time, a current of 100 mA flows through each of the plurality of light emitting elements 35 belonging to the second block B2 and the plurality of third blocks B3. Further, a current of 100 mA flows through the light emitting element 35d. On the other hand, a current of 400 mA÷3≈133 mA flows through each of the three light emitting elements 35a, 35b, and 35c belonging to the first block B1. As a result, the amount of light (luminous flux) of the three light emitting elements 35a, 35b, and 35c becomes approximately 1.3 times the amount of light (luminous flux) of each of the other plurality of light emitting elements 35.

The current flowing through each of the plurality of end light emitting elements 32 (light emitting elements 35a, 35b, 35c, 35d) is (400mA+100mA)÷4=125mA, and the current flowing through each of the plurality of intermediate light emitting elements 33 (the plurality of light emitting elements 35) is (400mA+100mA)÷4=125mA. The current flowing per one is 100 mA. Thereby, the current flowing through one of the plurality of end light emitting elements 32 (light emitting elements 35a, 35b, 35c, 35d) is changed from the current flowing through one of the plurality of intermediate light emitting elements 33 (multiple light emitting elements 35). can be made larger than. As a result, in the first light source module 3a, the light flux per unit area of the end light emitting section 30 (that is, the four light emitting elements 35a, 35b, 35c, 35d) is ) can be made larger than the luminous flux per unit area.

The current flowing through each of the four light emitting elements 35 constituting the second end light emitting section 36 is 100 mA, which is the same as the current flowing through each of the plurality of intermediate light emitting elements 33 constituting the intermediate light emitting section 31. It is. The current flowing through each of the four light emitting elements 35 constituting the second end light emitting section 36 is smaller than the current flowing through each of the plurality of end light emitting elements 32 constituting the end light emitting section 30 . Therefore, the second end light emitting section 36 has a smaller luminous flux per unit area than the end light emitting section 30.

The lighting fixture 1 is a single regular lighting unit that converts AC power supplied from a regular power source such as a grid power source into DC power, supplies the DC power to light source modules 3a and 3b, and lights up the light source modules 3a and 3b. The apparatus further includes a device. The regular lighting device includes a printed circuit that constitutes a power conversion circuit that performs power conversion, a constant current circuit that makes the direct current supplied to the light source modules 3a and 3b a constant current, and the like.

The second lens 62 is provided at the right end of the base portion 60 (that is, the end farthest from the functional component 4). The third lens 63 is provided between the left and right ends of the base portion 60 in the left-right direction. The base portion 60 is located so as to surround the first lens 61, the second lens 62, and the third lens 63. The base portion 60, the first lens 61, the second lens 62, and the third lens 63 are integrally formed of a transparent synthetic resin such as polycarbonate resin.

The end lens (first lens 61) is provided. The end lens (first lens 61) is a part of the lens block 6 that covers the end light emitting section 30 and the intermediate light emitting section 31.

The right end portion of the first lens block 6a is fixed to the front surface of the front plate 220 of the third instrument main body 22 by a fixture 66 inserted so as to fit into the first fixing hole 64. Further, the other portion of the first lens block 6a is fixed to the front surface of the front plate 220 of the third instrument main body 22 by a fixing tool 66 inserted into a second fixing hole 65 in the shape of a long hole.

Point e in FIG. 8 indicates a point on the rear surface of the front wall 52 where the light distributed by the first lens 61 has a peak luminous intensity (maximum luminous intensity).

In the lighting fixture 1 of this embodiment, the angle θ3 of aоe is set to be larger than the angle θ1 of aоb and smaller than the angle θ2 of aоc. Thereby, formation of a portion darker than other portions in front of the functional component 4 of the lighting fixture 1 can be suppressed. Further, the light distributed by the first lens 61 of the first lens block 6a and the light distributed by the first lens 61 of the second lens block 6b overlap, and the point b (in the horizontal direction on the cover 5) It is possible to prevent the luminous intensity at the center from becoming too high.

Furthermore, in the lighting fixture 1 of this embodiment, the line connecting the point о and the point e is set so as not to intersect with the point d (that is, the edge 410). Thereby, it is possible to suppress the appearance of a shadow on the front surface 41 of the functional component.

3. Effects In the lighting fixture 1 of this embodiment described above, the functional component 4 and the light source modules 3a, 3b are lined up in a row along the left-right direction (the longitudinal direction of the fixture main body 2). Therefore, in the lighting fixture 1 of this embodiment, the lighting fixture 1 can be slimmed down in the vertical direction.

In the lighting fixture 1 of this embodiment, each of the light source modules 3a and 3b has an end light emitting part 30 at the end adjacent to the functional component 4, which has a larger luminous flux per unit area than other parts. Therefore, in the lighting fixture 1 of this embodiment, the brightness (luminous flux) can be suppressed from decreasing in the portion where the functional component 4 is present, and the brightness is likely to be stable over the longitudinal direction of the lighting fixture 1.

Moreover, in the lighting fixture 1 of this embodiment, the light from the end light emitting part 30 can be distributed to the front side of the functional component 4 by the end lens (first lens 61) that covers the end light emitting part 30, so that It is possible to further suppress a decrease in brightness (luminous flux) in the area where the component 4 is present.

In addition, in the lighting fixture 1 of this embodiment, since the end lens (first lens 61) is constituted by a part of the lens block 6, the positioning of the first lens 61 to the end light emitting section 30 and the intermediate The third lens 63 can be aligned with the light emitting section 31 at the same time.

This can be tolerated by the two fixing holes 65, and damage to the lens block 6 can be suppressed.

Further, in the lighting fixture 1 of the present embodiment, the end light emitting section 30 includes a plurality of end light emitting elements arranged densely at intervals narrower than the intervals between the plurality of intermediate light emitting elements 33 constituting the intermediate light emitting section 31. Since the element 32 is included, it is easy to differentiate the luminous flux per unit area.

Furthermore, in the lighting fixture 1 of the present embodiment, each of the light source modules 3a and 3b allows the current flowing through one of the plurality of end light emitting elements 32 to be lower than the current flowing through one of the plurality of intermediate light emitting elements 33. The electric circuit 7 is configured to increase the size of the electric circuit 7. Therefore, in the lighting fixture 1 of this embodiment, a difference in luminous flux per unit area can be created between the end light emitting section 30 and the intermediate light emitting section 31 using electric power supplied from one power source.

The size of the luminous flux per unit area of the end light emitting parts 30 of the light source modules 3a, 3b is appropriately set according to the length of the functional component 4 in the left and right direction. For example, when another functional component 4 that is longer in the left-right direction than the functional component 4 of this embodiment is sandwiched between the light source modules 3a and 3b, the end light emitting section 30 in this case is different from the end light emitting section 30 of this embodiment.
