1. A lamp comprising:
- an LED module including a plurality of LEDs arranged in a first pattern on a substrate;
an optical system including a plurality of lenses in optical communication with the LED module;
a zoom apparatus that selectively relatively axially translates the optical system and the LED module, the zoom apparatus including;
an inner sleeve on which the LED module is disposed, and an outer sleeve on which the zoom apparatus is disposed, the inner and outer sleeves being slidably interconnected with the inner sleeve disposed inside the outer sleeve.

Abstract
A lamp (10, 30, 80) includes an LED module (16, 36, 86) having at least one LED (12, 32, 82) arranged on a substrate (14, 34, 84). An optical system includes at least one lens (18, 38, 88) in optical communication with the LED module (16, 36, 86). A zoom apparatus (20, 40, 90) selectively adjusts the relative axial separation of the optical system and the LED module (16, 36, 86). In one embodiment (30), the zoom apparatus (40) is slidably adjustable. In a another embodiment (80), the zoom apparatus (90) is rotatably adjustable.

4. A lamp comprising:
-
an LED module including at least one LED arranged on a rigid substrate;
an optical system including at least one lens in optical communication with the LED module; and
a zoom apparatus that selectively adjusts the relative axial separation of the optical system and the LED module, the zoom apparatus including;
a first sleeve having the LED module rigidly arranged thereon, the first sleeve further having a first threading arranged thereon; and
a second sleeve having a second threading arranged thereon that is adapted to cooperate with the first threading such that the first sleeve and the second sleeve are relatively movable in a screwing fashion, the second sleeve further having the optical system rigidly arranged thereon. - View Dependent Claims (5)

7. A lamp comprising:
-
an LED module including at least one LED arranged on a substrate;
an optical system including at least one lens in optical communication with the LED module; and
a zoom apparatus that selectively adjusts the relative axial separation of the optical system and the LED module, the zoom apparatus including a first sleeve having the LED module disposed thereon and a second sleeve having the optical system disposed thereon, the second sleeve slidingly connected with the first sleeve, the zoom apparatus further including a mechanical interlock between the first and the second sleeves that prevents relative rotation therebetween, the mechanical interlock including;
a protrusion on one of the first and the second sleeves, the protrusion being aligned parallel to the optical axis, and a groove on one of the first and the second sleeves that receives the protrusion to prevent relative rotation of the first and the second sleeves.
