Abstract
A trim member for a lighting device module includes an annular body having a first end portion that is connectable to a housing of the lighting device module and has a light receiving opening, and a second end portion opposite to the first end portion. The second end portion has a light emitting opening and is configured to be positioned outside of the housing of the lighting device module. A first curved or tapered surface extends from the light receiving opening toward the light emitting opening, and has a diameter that increases toward the light receiving opening. A second curved or tapered surface extends from the first curved or tapered surface to the light emitting opening, and has a diameter that increases toward the light emitting opening.
Claims20
A trim member for a lighting device module, the trim member comprising an annular body having:
- a first end portion that is connectable to a housing of the lighting device module and having a light receiving opening that is arranged to receive light from the lighting device module when the first end portion is connected to the housing of the lighting device module;
- a second end portion opposite to the first end portion, and that is configured to be positioned outside of the housing of the lighting device module when the first end portion is connected to the housing of the lighting device module, the second end portion having a light emitting opening;
- a central channel defining a light passage extending through the annular body, from the light receiving opening to the light emitting opening;
- a first curved or tapered surface extending from the light receiving opening toward the light emitting opening, the first curved or tapered surface having a diameter that continuously increases in a direction toward the light receiving opening;
- and
- a second curved or tapered surface extending from the first curved or tapered surface to the light emitting opening, the second curved or tapered surface having a diameter that increases toward the light emitting opening.

- a first curved or tapered surface extending from the light receiving opening toward the light emitting opening, the first curved or tapered surface having a diameter that continuously increases in a direction toward the light receiving opening;
- and
- a second curved or tapered surface extending from the first curved or tapered surface to the light emitting opening, the second curved or tapered surface having a diameter that increases toward the light emitting opening;
- wherein the first curved or tapered surface is light-reflective and is configured to reflect a peripheral portion of light from the lighting device module back toward the housing of the lighting device module, while allowing a central portion of light from the lighting device module to pass through the central channel;
- and
- wherein the second curved or tapered surface has a black or light absorbing material, coating or treatment.

6 more elements
A method of making a lighting device module with a trim member, the method comprising:
- arranging a light source in a housing of a lighting device module for emitting light from the housing;
- connecting a first end portion of an annular body to the housing of the lighting device module, the first end portion having a light receiving opening to receive light from the housing of the lighting device module;
- positioning a second end portion of the annular body outside of the housing of the lighting device module when the first end portion is connected to the housing of the lighting device module, the second end portion having a light emitting opening;
- providing the annular body with a first curved or tapered surface extending from the light receiving opening toward the light emitting opening, the first curved or tapered surface having a diameter that continuously increases in a direction toward the light receiving opening;
- and
- providing the annular body with a second curved or tapered surface extending from the first curved or tapered surface to the light emitting opening, the second curved or tapered surface having a diameter that increases toward the light emitting opening.
