LIGHT SOURCE UNIT AND LIGHTING FIXTURE

摘要

A light source unit includes an attachment body including an attachment board, a circuit board having a first surface in contact with the attachment board and a second surface on which lighting sources are mounted. The light source unit further includes a cover attached to the attachment body so as to cover the second surface of the circuit board. The cover includes a panel covering the circuit board and a pair of inner flanges each of which extending from both ends of the panel in a width direction of the panel so as to come toward each other. The circuit board is supported by being held between the pair of inner flanges and the attachment board of the attachment body.

主权项

1. A light source unit comprising:
an attachment body having an elongated shape, which has a longer side in a length direction and a shorter side in a width direction shorter than the longer side, and including an attachment board; a circuit board having a first surface in contact with the attachment board and a second surface on which lighting sources are mounted; and a cover having an elongated shape, which has a longer side in a length direction and a shorter side in a width direction shorter than the longer side, and attached to the attachment body so as to cover the second surface of the circuit board, with the length direction of the cover being in parallel to the length direction of the attachment body, wherein: the cover includes:
a panel having an elongated shape, which has a longer side in a length direction and a shorter side in a width direction shorter than the longer side, and covering the circuit board; anda pair of inner flanges each of which has a board shape and which extend from both ends of the panel in the width direction of the panel so as to come toward each other, and the circuit board is supported by being held between the pair of inner flanges and the attachment board of the attachment body.
