Light adjustable lighting fixture
An electrical lighting fixture has a light source, like an LED module, located at the top end of the fixture and a light shroud attached to the LED module. The shroud has a stationary base member fixed to the LED module and a movable member overlaying the base member. Both the base member and movable member have side openings. The movable member is rotatably adjustable around the base member to control the size of the openings and therefore the amount of light radiating from the LED module. A vertically adjustable member circumscribes the movable member and can be moved vertically along the surface of the movable member to control the vertical direction of light radiating from the LED module.
1 . An electrical lighting fixture comprising:
an elongated lighting fixture body having a top end;
a light source providing illuminating lighting from the lighting fixture, said light source being located at the top end of the lighting fixture body; and
a light shroud attached to the light source, said light shroud comprising a stationary base member affixed to the light source, said base member having at least one opening through which illuminating light from the light source radiates, and a movable member circumscribing and overlaying the base member, the movable member having an opening through which illuminating light from the light source radiates, the movable member being adjustable from a position in which it totally covers the opening of the base member, to positions in which it partially covers the opening of the base member, thereby controlling the size of the opening of the base member, the light shroud being adjustable in relation to the light source in order to vary the direction and amount of illuminating light radiating from the light source.
2 . The electrical lighting fixture as in claim 1 wherein the movable member is adjustably rotatable around the base member to control the size of the opening of the base member in order to control the amount of illuminating light radiating laterally and horizontally outward from the light source through both the openings.
3 . The electrical lighting fixture as in claim 2 further comprising a vertically adjustable member circumscribing the movable member, wherein the position of the vertically adjustable member along the surface of the movable member controls the vertical direction of the illuminating light radiating from the light source.
4 . The electrical lighting fixture as in claim 1 further comprising a vertically adjustable member circumscribing the movable member, wherein the position of the vertically adjustable member along the surface of the movable member controls the vertical direction of the illuminating light radiating from the light source.
5 . The electrical lighting fixture as in claim 1 wherein the light source is an LED module.
6 . An electrical lighting fixture comprising:
an elongated lighting fixture body having a top end;
a light source providing illuminating light from the lighting fixture, said light source being affixed to the top end of the lighting fixture body; and
a light trim unit attached to the light source, said light trim unit having dual side openings through which illuminating light from the light source radiates, the light trim unit being adjustable in relation to the light source in order to vary the direction and amount of illuminating light radiating from the light source.
7 . The electrical lighting fixture as in claim 6 further comprising a vertically adjustable member circumscribing the light trim unit, wherein the position of the vertically adjustable member along the surface of the light trim unit controls the vertical direction of the illuminating light radiating from the light source.
8 . The electrical lighting fixture as in claim 6 wherein the light source is an LED module.
9 . An electrical lighting fixture comprising:
an elongated lighting fixture body having a top end;
a light source providing illuminating lighting from the lighting fixture, said light source being located at the top end of the lighting fixture body;
a light shroud attached to the light source, said light shroud having at least one opening through which illuminating light from the light source radiates, the light shroud being adjustable in relation to the light source in order to vary the direction and amount of illuminating light radiating from the light source; and
a vertically adjustable member circumscribing the light shroud, wherein the position of the vertically adjustable member along the surface of the light shroud controls the vertical direction of the illuminating light radiating from the light source.
10 . The electrical lighting fixture as in claim 9 wherein the light source is an LED module.
