ILLUMINATION DEVICE AND ILLUMINATION UNIT

摘要

According to one embodiment, an illumination device includes a first light-transmissive member, a first chassis, and a first semiconductor light emitting unit. The first light-transmissive member has first and second member ends. The first chassis includes a first base portion, first and second side portions. The first base portion is separated from the first light-transmissive member and has first and second base ends. The first side portion extends from the first base end toward the first member end and has first and second end portions. The second side portion extends from the second base end toward the second member end and has third and fourth end portions. A distance between the first and third end portions is shorter than a distance between the second and fourth end portions. The first semiconductor light emitting unit is provided between the first and second side portions.

主权项

1. An illumination device, comprising:
a first light-transmissive member having a first member end and a second member end, the second member end being separated from the first member end in a first direction; a first chassis including
a first base portion separated from the first light-transmissive member in a second direction intersecting the first direction, the first base portion having a first base end and a second base end, the second base end being separated from the first base end in the first direction,a first side portion extending from the first base end toward the first member end, the first side portion having a first end portion and a second end portion, the first end portion being connected to the first base end, the second end portion being on a side of the first member end, anda second side portion extending from the second base end toward the second member end, the second side portion having a third end portion and a fourth end portion, the third end portion being connected to the second base end, the fourth end portion being on a side of the second member end,a distance along the first direction between the first end portion and the third end portion being shorter than a distance along the first direction between the second end portion and the fourth end portion; and a first semiconductor light emitting unit provided between the first side portion and the second side portion in a space between the first light-transmissive member and the first base portion.
