Abstract

Light systems and light fixtures are described herein. In one embodiment, a light system may include a light fixture, a first diffuser attached to the light fixture, where the first diffuser and the light fixture define a cavity, a first LED producing ambient light within the cavity, and a second LED producing directional light in the cavity, where the first diffuser is adapted or configured to receive the ambient light and the directional light and emit the ambient light and the directional light external to the light system. In another embodiment, a light fixture may include a first LED subsystem including a first LED and a diffuser, the first LED subsystem adapted or configured to produce ambient light, a second LED subsystem including a second LED and a reflector, the second LED subsystem adapted or configured to produce directional light, where the directional light passes through the diffuser.

Claims (26)

1. A light system, comprising:

a linear light fixture;

a first diffuser attached to the light linear fixture, wherein the first diffuser and the linear light fixture define a cavity and the first diffuser can be removed, replaced, or interchanged from the linear light fixture;

a first LED producing ambient light within the cavity, the first LED comprising a second diffuser configured or adapted to produce the ambient light; and

a second LED producing directional light in the cavity, the second LED comprising a lens configured or adapted to produce the directional light;

wherein the first diffuser is adapted or configured to receive the ambient light and the directional light and produce the ambient light and the directional light external to the light system, the first diffuser masking the first LED and the second LED from a view external to the light system when the first LED and the second LED are not powered; and

wherein the second LED is coupled to a repositionable structure in the cavity, the second LED being repositionable to change a position or angle of projection of the directional light.

2. The light system of claim 1 , wherein the second LED comprises a light reflector.

3. The light system of claim 1 , wherein the emitted directional light comprises a directional light beam with an angle of less than 60 degrees relative to a transmission surface face of the first diffuser.

4. The light system of claim 1 , wherein the first LED and the second LED are independently operable.

5. The light system of claim 1 , wherein the linear light fixture further comprises a socket coupled to the repositionable structure of the second LED, the repositionable structure configured to allow for rotary movement of the second LED within the linear light fixture.

6. The light system of claim 1 , wherein the repositionable structure comprises a ball mount or a pivot.

7. The light system of claim 1 , wherein the ambient light forms a batwing projection pattern.

8. The light system of claim 1 , wherein selected areas of the first diffuser emit the light differently compared to other areas of the first diffuser or lens.

9. A linear light fixture for providing ambient light and directional light, the linear light fixture comprising:

a first LED subsystem comprising a first LED and a diffuser, the first LED subsystem adapted or configured to produce ambient light;

a second LED subsystem comprising a second LED and a reflector, the second LED subsystem adapted or configured to produce directional light;

wherein the directional light passes through the diffuser and the diffuser masks the first LED and the second LED from a view external to the linear light fixture when the first LED and the second LED are not powered;

wherein the diffuser can be removed, replaced, or interchanged from the linear light fixture; and

wherein the second LED subsystem is coupled to a repositionable structure in an internal portion of the linear light fixture, the second LED being repositionable to change a position or angle of projection of the directional light.

10. The light fixture of claim 9 , wherein the diffuser comprises either a light lens or a light filter.

11. The linear light fixture of claim 9 , wherein the directional light is directable to an angle relative to a transmission surface face of the diffuser.

12. The linear light fixture of claim 9 , wherein the ambient light forms a batwing projection pattern.

13. The linear light fixture of claim 9 , wherein the first LED subsystem and the second LED subsystem are independently operable.

14. The light linear fixture of claim 9 , further comprising:

a linear light source producing light rays in an opposite direction of the emitted ambient light from the first LED subsystem.
