Abstract

A lighting unit includes a housing, a first cover, and a second cover. The housing is configured to house a light source and a circuit body constituting a circuit between the light source and an outside of the housing. The first cover is mountable to the housing and configured to emit light from the light source to the outside of the housing. The second cover is mountable to the housing and includes a cover-side attachment portion attachable to an attachment hole of a lighting attachment member. The second cover is configured to emit the light from the light source to the outside of the housing through the attachment hole. The first cover and the second cover are selectively mountable to the housing.

Claims

1. A lighting unit comprising:

a housing configured to house a light source and a circuit body constituting a circuit between the light source and an outside of the housing;

a first cover mountable to the housing and configured to emit light from the light source to the outside of the housing; and

a second cover mountable to the housing and including a cover-side attachment portion attachable to an attachment hole of a lighting attachment member, the second cover being configured to emit the light from the light source to the outside of the housing through the attachment hole,

wherein the first cover and the second cover are selectively mountable to the housing.

2. The lighting unit according to claim 1, wherein the housing comprises a housing-side attachment portion to be attached to the lighting attachment member.

3. The lighting unit according to claim 1, wherein

the first cover comprises a first deformation restricting rib,

the second cover comprises a second deformation restricting rib,

the housing comprises a deformation restricting groove selectively receivable of the first deformation restricting rib and the second deformation restricting rib, and

the cover-side attachment portion is attachable to the attachment hole of the lighting attachment member by rotation of the cover-side attachment portion.

4. The lighting unit according to claim 1, wherein

the housing is formed of a member that does not transmit light,

the first cover is formed of a member that transmits light, and

the second cover is formed of a member that does not transmit light.
