As a result, there is no end cover between the first light source units 51, and the light extraction efficiency can be improved. Also in this case, it is possible to prevent the shadow of the first connector 513 of the first light source unit 51 from appearing on the translucent cover 254 . Insufficient amount of light at the ends of the lamp 5 in the longitudinal direction can also be resolved.

2. Attaching the Lamp to the Mounting Device (1) Overall length of the projecting portion It is attached to the attachment tool 3 by engaging with 530 .
The projecting portion 530 of the lamp 5 may be provided over the entire length of the lamp side base 53 in the longitudinal direction, or may be provided at a portion of the attachment 3 corresponding to the lamp fixture 34 . When the lamp side base 53 is formed by extrusion molding or pultrusion molding, it is preferable to provide it over the entire length. Further, when the position of the lamp fitting fixture 34 is determined at the construction site, it is possible to improve workability by forming the projecting portion 530 over the entire length. In other words, in a lighting apparatus in which a lamp is attached to a mounting fixture after the mounting fixture has been provided on the installation surface, if the lamp mounting fixture is of a fixed type (a structure that cannot be moved in the longitudinal direction), the lighting fixture cannot be easily mounted. is to solve In addition, in a structure in which a lamp is easily attached to a fixture provided with a fixed lamp fixture, the fixture may not include the first light source unit. In other words, in a lighting device that is long in a first direction, the lighting device includes a light source section having an LED element on a substrate, a holder that supports the substrate, and a mounting fixture that engages with the holder. The engaging portion may be provided in a region longer than the entire length of the fixture in the first direction, and may be provided over the entire length in the first direction.

(2) Structure of Protruding Portion The structure of the protruding portion 530 is not particularly limited as long as it can be engaged with the engaging portion 340 of the lamp fixture 34 . In addition, this can prevent the lamp 5 from falling off. In addition, when the installation of the lamp 5 is carried out at a construction site, the installation can be easily carried out, and workability can be improved.
For example, as shown in FIG. 16(a), the protruding portion 1530 has a triangular shape, and includes an inclined region 1530a that protrudes in the lateral direction as it moves away from the attachment tool, and a lateral direction extending from the front side end of the inclined region 1530a. It may have a flat region 1530b extending inward in the direction.
For example, as shown in FIG. 16(b), the projecting portion 2530 may have a rectangular groove region 2530a with an open front side (engagement side). The engaging portion 340 of the lamp fitting 34 abuts against the abutting portion 2530c, which is the bottom portion forming the groove region 2530a, and the engaging portion 340 is disengaged from the abutting portion 2530c (in the lateral direction). It has an extending portion 2530b that extends from the outer side) to the engaging portion 340 side (front side) of the lamp fitting fixture . The stretched portion 2530b may be stretched in the front and back direction, may be stretched outward in the widthwise direction and inclined toward the front side (outward) as in the embodiment, or may be stretched in the widthwise direction. You may extend|stretch to the front side (inward) in an inclined shape. Thereby, it is possible to prevent the engaging portion 340 from coming off. In other words, in a lighting device in which a lamp is detachably attached to a mounting fixture (lamp mounting fixture), the problem of the detachment of the lamp is solved. In addition, in a structure in which the lamp does not easily come off from the mounting fixture (lamp mounting fixture), the lighting fixture may not include the first light source unit. In other words, in a lighting device comprising a light source section including an LED element on a substrate, a holder that supports the substrate, and a mounting fixture that is attached by engaging the holder, the engaged portion of the holder If it has an abutting portion with which the engaging portion of the mounting device abuts, and an extending portion extending along the engaging portion from the side of the abutting portion where the abutment of the engaging portion is released. good.
In the embodiment, the lamp fixture 34 engages with the lamp fixture side base 53 from the outside in the short direction, but it may be configured to engage from the inside in the short direction.

One rib portion may be provided on the instrument side back base and the other rib portion may be provided on the instrument side front base, or both rib portions may be provided on the instrument side front base. However, it may be provided on both the instrument side back base and the instrument side front base. As a result, a pair of (two) harnesses can be arranged separately on both sides in the short direction. In other words, in a lighting device in which a lamp is detachably attached to a mounting fixture and which has feed wiring for electrically connecting to another lighting device, the feed wiring may cross or the lighting may be detached when the lighting is attached or detached. This is to solve the problem that there is a risk of being caught on the wiring. It should be noted that the lighting device that uses feed wiring may be a lighting device that does not include the first light source unit. In other words, in a lighting device elongated in the first direction in which a lamp is detachably attached to a mounting fixture, the mounting fixture includes a first base (corresponding to the fixture side front base 37 of the first embodiment) and a second base ( in the first embodiment), and the base provided in a state of facing each other, in the first direction, on both sides of the second direction sandwiching the center in the second direction orthogonal to the first direction. and two harnesses for feed wiring are arranged separately in two spaced apart internal spaces on both sides in the second direction. In this case, the internal space may be configured with a rib portion as in the first embodiment, or may be configured with a recessed portion (groove portion). In particular, a harness connected to a connection portion located on one side in the second direction of the terminal block is arranged in an internal space located on one side in the second direction, and the harness is located on the other side of the terminal block in the second direction. It is preferable that a harness connected to the connecting portion to be connected is arranged in the internal space located on the other side in the second direction.
