ΔW1: shift amount in the short direction of the LED module 120 (substrate 120b) with respect to the center C1 in the short direction of the frame 110-1 ΔW1 ≦ W5
W6 = W3 + ΔW1 (ΔW1 = W6-W3)
W7 = W3-ΔW1 (ΔW1 = W3-W7)
W6 = W7 + (2 × ΔW1)
W6 + W7 = W2

Only when one of the pair of (two) through holes formed in the LED module 120 is completely opened, it can be determined that the LED module 120 (substrate 120b) is a poorly arranged lamp. In the first embodiment, the pair of (two) through holes formed in the short direction of the frame 110-1 penetrate from the mounting side of the frame 110-1. When mounting is performed, it is possible to determine good / bad even after the cover is mounted on the frame 110-1 and assembly of the light source unit 100 is completed. For this reason, there is no possibility that the assembling work in the post-process will be continued in an unsatisfactory state, or the unsatisfactory light source unit 100 will not be shipped.

  As described above, the frame (base) according to the first embodiment has the pair of through holes H1 and H2 formed therein, and the light source unit (the lamp) does not have any one of the through holes covered with the LED module. In the case of the open state, it is detected that the arrangement state of the LED modules is not good.

<Summary of actions and effects>
It is possible to determine whether the arrangement of the LED module (substrate) with respect to the frame is a good arrangement or an unfavorable arrangement in all directions by combining the configurations described in the first to fifth embodiments and combinations thereof. Can be.
(1) It is possible to determine whether the arrangement of the LED modules in the lateral direction of the frame described in the first to fifth embodiments shown in FIG. .
(2) In addition, the arrangement of the LED modules in the longitudinal direction of the frame shown in FIG. 21 (b) and the arrangement of the LED modules in the oblique direction of the frame in which the lateral and longitudinal displacements are combined are good. Alternatively, it can be determined whether the arrangement is a poor arrangement.
(3) Further, it is also possible to determine whether the LED module is arranged in a good or bad manner in the rotation direction of the frame shown in FIG.

  In this way, it is possible to accurately determine whether the lamp is good or bad. Preferably, in Examples 1 to 5, when the arrangement of the LED modules is confirmed, if a part of the through hole provided in the frame is opened, the through hole is sealed with an adhesive tape or the like. At this time, the adhesive tape may also be used for other functions such as fixing the electric wire. Confirmation of the arrangement of the LED modules can be performed in a lamp assembly process, shipping inspection, delivery (acceptance) inspection, pre-construction inspection, and the like.

  The identification mark M can be laid at any position that is not affected by the size or shape of the LED module 120 (substrate 120b), and the through hole H7 is a position that overlaps with the identification mark M, and depends on the size and shape of the frame 110-5. Since the LED module can be formed at an arbitrary position that is not affected, as a result of checking the arrangement of the LED modules, the position can be determined so that the through hole provided in the frame is completely closed. Therefore, it is not necessary to seal the through-hole with an adhesive tape or the like.

(Example 6)
A sixth embodiment will be described with reference to FIG.
FIG. 22 is a partially enlarged perspective view of the light source unit 100 according to the sixth embodiment.

  FIG. 22A shows a state in which an L-shaped protrusion 115 is cut and raised from the frame 110-6, and FIG. 22B shows a state in which a mountain-shaped protrusion 116 is cut and raised from the frame 110-6. Is shown.

  In Examples 1 to 5, the through holes H are formed in the frame, and the arrangement of the substrate 120b is confirmed. In the sixth embodiment, a through hole formed by cutting and raising a part of the frame toward the mounting side is used as a through hole H for confirming the arrangement of the substrate 120b. In the sixth embodiment, FIGS. 22A and 22B show two examples in combination with the first embodiment. The cut-out projections 115 and 116 are used for mounting spring mounting brackets, a power supply, a wiring fixture, and the like, which are arranged on the mounting side of the frame. Since the rigidity of the frame 110-6 is increased by attaching a structure other than the frame 110-6, the strength of the lamp is improved.

Although the first to sixth embodiments have been described above, they are particularly useful in the following cases.
In the process of successively assembling the lamps without waiting for the adhesive to completely solidify for the purpose of shortening the production (assembly) time for the lamps in which the LED module is adhered and fixed to the flat surface using the adhesive, Therefore, there is a possibility that the LED module is shifted. By using the configuration or method of the first embodiment in such a process, even after the cover is attached, only the lamp in which the light source is arranged in a favorable position without depending on the positioning of the LED module Can be reliably selected. Therefore, it is possible to prevent the unsatisfactoryly arranged lamps from flowing out to the next process, thereby preventing the unsatisfactory lamps from being shipped by mistake.

The lighting device 10A includes a lighting fixture 200A and a light source unit 100A. Two LED modules 1201 and 1202 connected in the longitudinal direction are attached to the light source unit 100A. Therefore, the length of illumination device 10A in the longitudinal direction is approximately twice that of illumination device 10 of the first embodiment. A specific example of the length of the lighting device 10A is approximately 8 feet.

<Light source unit 100A, lighting fixture 200A>
As shown in FIGS. 26 to 28, in the light source unit 100A, two LED modules 120 arranged adjacent to each other in the longitudinal direction are attached to the frame 110-7. In the second embodiment, the two LED modules 120 are LED modules 1201 and 1202. That is, the light source unit 100A includes two substrates 120b connected in the longitudinal direction and the light emitting element 120a mounted on each substrate 120b on the substrate mounting surface 111a of the frame 110-7.

The light source unit 100A includes a frame 110-7, two LED modules 120 (LED modules 1201 and 1202), a cover 130, two power supply devices 140 (power supply devices 1401 and 1402), and three mounting fixtures 150 (mounting fixtures 1501 and 1502). , 1503).
The three fixtures 150 (the fixtures 1501, 1502, and 1503) are connected to leaf springs 2301, 2302, and 2303 arranged in the lighting fixture 200A.

Here, the positions where the three fixtures 150 (the fixtures 1501, 1502, and 1503) of the light source unit 100A are arranged on the light source unit 100A are connected to the three leaf springs 2301, 230, and 2303 of the lighting fixture 200A, respectively. At this time, the adjustment is performed so that the light source unit 100A is attached to substantially the center in the longitudinal direction of the lighting fixture 200A.
That is, when the light source unit 100A is fixed to the luminaire 200A, the position at which the mounting fixture 1502 at the center is disposed in the longitudinal direction of the light source unit 100A so that the stress in the longitudinal direction of the light source unit 100A is balanced. Offset to the end. In addition, the leaf spring 2302 at the center of the lighting fixture 200A may be offset to either end in the longitudinal direction of the lighting fixture 200A together with the attachment 1502, or only the leaf spring 2302 at the center of the lighting fixture 200A may be offset. The lighting fixture 200A may be offset to any end side in the longitudinal direction.
By offsetting in this way, it is possible to eliminate the imbalance in the stress in the longitudinal direction depending on the orientation of the fixture 1502 and the leaf spring 2302 in the central portion. Also, no gap is generated between the light source unit 100A and the lighting fixture 200A.

  The frame 110-7 is approximately twice as long as the frames 110-1 to 110-5 of the first embodiment.
