Abstract

A multiple LED light device with adjustable angle function has multiple LED-units, each including a housing and extensions that fit within tracks to adjust the LED'"'"'s light beam angle, thereby enabling a plurality of the LED-units to direct light beams to different desired locations.

Claims

1. A multiple LED light device having an adjustable angle function, comprising:

a device housing;

at least one LED unit having extensions that fit within respective tracks, wherein the tracks have any geometric shape that permits the LED unit to be moved in a first plane, the LED unit also being movable about the extensions in a second plane to enable light beams from the LED unit in a desired direction, and wherein said LED unit includes a lens and a reflective housing which are separate pieces;

circuit and power means within said housing for supplying electric signals to cause said LED unit to emit said light beams; and

attachment means for installing the light device on an surface.

2. A multiple LED light device having an adjustable angle function as claimed in claim 1, wherein said extensions are freely movable within said track to enable said LED-unit to be moved to a desired angle when a force is applied to said LED-unit.

3. A multiple LED light device having an adjustable angle function as claimed in claim 1, wherein said power means changes incoming DC or AC current into a current and voltage for triggering an LED in said LED unit.

4. A multiple LED light device having an adjustable angle function as claimed in claim 1, wherein the light device is adapted for use indoors, outdoors, in cars, trucks, vans, boats, vessels, airliners, recreational vehicles, and in any area inhabited by human beings.

5. A multiple LED light device having an adjustable angle function as claimed in claim 1, wherein the attachment means comprises glue, double-sided tape, foam tape, hook and loop tape, chemical adhesives, a screw, a phone hook, a catch, or a rivet.

6. A multiple LED light device having an adjustable angle function as claimed in claim 1, wherein the tracks includes stoppers for limiting movement of said LED unit beyond a predetermined angle.

7. A multiple LED light device having an adjustable angle function as claimed in claim 1, wherein the tracks are curved and said LED unit is therefore cause to rotate when said extensions are moved in said path, said LED unit being additionally free to swivel about said extensions in a second place different from the plane of rotation.

8. A multiple LED light device having an adjustable angle function as claimed in claim 1, wherein the LED unit is one of a plurality of units having a desired size, dimension, surface arrangement, and number of units.

9. A multiple LED light device having an adjustable angle function as claimed in claim 1, further comprising means for causing LEDs in the device to exhibit predetermined lighting functions.
