  The light source unit 1 includes a plurality of light emitting diodes (LEDs) 10, a rectangular mounting substrate 11, a receptacle connector (first connector) 12, a protective cover 14, and a mounting plate 15. The light source unit 1 preferably further includes a lens block (light distribution control member) 13 and a reflection sheet 16.

  The LED 10 is a package-type white LED that is conventionally known. The plurality of LEDs 10 are mounted (surface mounted) on the lower surface of the mounting substrate 11 by soldering electrodes (anode electrode and cathode electrode) to lands (not shown) formed on the lower surface of the mounting substrate 11. The

  The mounting board 11 is formed with the lands arranged vertically and horizontally at regular intervals and a conductor (copper foil) electrically connecting the lands on the lower surface. In addition, the first connector 12 is mounted at the front center in the left-right direction on the lower surface of the mounting substrate 11. The first connector 12 is electrically connected to all the LEDs 20 via a conductor, and is detachably connected to a plug connector (second connector 7) described later. However, the LEDs 20 do not necessarily have to be mounted on all lands, and the LEDs 20 may be mounted by thinning some lands.

  The reflective sheet 16 is formed by forming a reflective layer made of a material having a relatively high reflectance on the surface (lower surface) of a sheet material made of an insulating material such as synthetic rubber or synthetic resin. In the reflection sheet 16, through holes (not shown) for exposing the LEDs 20 and the lands are formed side by side in the vertical and horizontal directions. That is, the light emitted from the LEDs 20 is reflected downward by the reflection sheet 16 by arranging the reflection sheet 16 on the lower surface side of the mounting substrate 11.

  As shown in FIG. 1, the lens block 13 is a synthetic resin in which a plurality of (in the illustrated example, 64) lenses 130 that diffuse the light of the LED 20 and a coupling member 131 that couples the plurality of lenses 130 are translucent. (For example, an acrylic resin) is integrally molded.

  In the coupling member 131, a recess 132 for escaping the first connector 12 is provided at the center in the left-right direction on the front side. In addition, a pair of protrusions 133 are provided on the left and right sides of the front end side of the recess 132. The pair of protrusions 133 are L-shaped, and are formed integrally with the coupling member 131 so that their tips (lower ends) face each other (see FIG. 2). The pair of protrusions 133 are provided at a length and a position that overlap with the insertion port side (front side) end portion of the first connector 12 when viewed in the vertical direction (see FIG. 2A).

  The lens block 13 is attached to the mounting plate 15 together with the mounting substrate 11 and the reflection sheet 16 by screwing. The mounting plate 15 is formed of a rectangular metal plate. A notch is formed in each of the left and right edges of the mounting plate 15 in the center in the front-rear direction. Further, three fixing pieces 150 are arranged at equal intervals in the left-right direction on the front edge of the mounting plate 15. These three fixed pieces 150 are all formed in a rectangular flat plate shape. However, rectangular recesses 151 are formed at the front end edges of the two fixed pieces 150 at both the left and right ends. Furthermore, a screw insertion hole (not shown) is provided in the center of the rear end portion of the mounting plate 15 in the left-right direction.

  A plug connector (second connector 7) is detachably connected to the first connector 12. The 2nd connector 7 is provided in the front-end | tip of the electric wire 6 which consists of a 2-core covered electric wire. The electric wire 6 is electrically connected to an output terminal (output terminal block 54) of the power supply unit 5, and forms a power feeding path from the power supply unit 5 to the light source unit 1. However, the connector 60 is provided in the middle of the electric wire 6, and the electric wire 6 is configured to be separable by the connector 60.

  As shown in FIG. 5, the protective cover 14 is configured to cover a part of the first connector 12, the second connector 7, and the electric wire 6. As shown in FIG. 4, the protective cover 14 is formed in a key shape from a synthetic resin material such as a fluororesin. However, the protective cover 14 is preferably colored as a whole or made of a white material.

  The protective cover 14 includes a rectangular flat plate-shaped main portion 140 with rounded corners, a trapezoidal bent portion 141, and a strip-shaped connecting portion 142 that connects one end edge of the main portion 140 and a lower bottom portion of the bent portion 141. And are integrally formed. In the main part 140, circular through holes 144 are formed so as to be arranged in the left-right direction. In the connection portion, the width dimension of the bending portion 141 is larger than the width dimension of the connection portion 142. In the bent portion 141, the portion that protrudes outside the connecting portion 142 becomes the hook portion 143.
