Abstract

A lighting device having a support module supporting LEDs and having an outer perimeter defining a curved portion, and a housing with an inner surface having a curved portion configured to receive the curved portion of the support module to enable the disk to be aimed, while the curved portions of the disk and housing remain in contact. Optional adjustment means facilitate aiming of the support module without the need to open the sealed LED module.

Claims

1. A lighting device installed inground comprising:

a support module supporting a plurality of LEDs and having an outer perimeter defining a curved portion;

a first housing having an inner surface defining a curved portion configured and arranged to receive the curved portion of the support module and hold the support module in a desired orientation, the curved portion of the first housing having an upper end and a lower end and the lower end is located radially inward of the upper end such that the curved portion of first housing opens upward;

a lens enclosing the support module within the first housing such that the curved portion of the first housing opens upward toward the lens;

wherein the support module outer perimeter curved portion is configured and arranged to remain in contact with the first housing inner surface curved portion at any of a plurality of desired orientations.

2. The device of claim 1, further comprising a means for adjusting the support module orientation within the first housing.

3. The device of claim 2, wherein the means for adjusting comprises a worm gear and an adjustment screw.

4. The device of claim 1, wherein the support module comprises a spherical outer surface and the first housing comprises a spherical inner surface configured and arranged to receive the spherical outer surface of the support module when the support module is oriented in any one of a plurality of orientations.

5. The device of claim 1, further comprising a second housing, with a longitudinal axis, configured and arranged to receive the first housing.

6. The device of claim 5 the second housing configured to be placed inground.

7. The device of claim 5, wherein the support module comprises a spherical outer surface and the first housing comprises a spherical inner surface configured and arranged to receive the spherical outer surface of the support module when the support module is oriented in any one of a plurality of orientations.

8. The device of claim 7, further comprising a pair of pivot screws between the first housing and the support module that are configured and arranged to allow the support module to pivot within the first housing, wherein the pivot screws define a first pivot axis of the support module.

9. The device of claim 7, wherein the support module is tilted within plus or minus about 25 degrees from vertical.

10. The device of claim 9, wherein the support module is tilted within plus or minus about 15 degrees from vertical.

11. The device of claim 7, wherein a light direction axis of the support module is within a solid angle with the longitudinal axis of the second housing of about 25 degrees.

12. The device of claim 11, wherein a light direction axis of the support module is within a solid angle with the longitudinal axis of the second housing of about 25 degrees.

13. The device of claim 11, further comprising an intermediate housing and a second pair of pivot screws defining a second pivot axis for the support module, wherein the second pivot axis is about normal to the first pivot axis, wherein the light direction axis is aimable over a solid angle.

14. The device of claim 11, wherein the first housing is rotatable within the second housing, wherein the first pivot axis rotates with respect to the longitudinal axis.

15. The device of claim 1, further comprising a lens secured to the first housing enclosing the support module within the first housing.
