Abstract
A flashlight is provided having a housing, a reflector and a light source, such as an LED. Preferably, an alignment structure is provided for aligning the LED with the focal axis of the reflector. For instance, the LED may be fixed to a circuit board, and the flashlight may include an alignment element configured to mate with the LED to position the LED at a pre-determined position. Alternatively, the LED may be electrically connected with a circuit board, and the circuit board my include an opening for receiving the LED to position the LED at a pre-determined position.
Claims35
A flashlight, comprising:
- a housing;
- a reflector disposed within the housing at a predetermined position relative to the housing, wherein the reflector has a focal point along a focal axis;
- a lamp assembly, comprising:
- a circuit board;
- an LED fixedly connected to the circuit board;
- a heat sink;
- an alignment element configured to mate with the LED to position the LED at a predetermined position relative to the alignment element;
- a cap configured to cooperate with the heat sink to position the alignment element and the circuit board between the cap and the heat sink;
- and
- a lamp housing configured to mate with the alignment element to position the alignment element at a predetermined position relative to the lamp housing;
- wherein the lamp assembly is configured to mate with the housing to position the lamp assembly at a predetermined position relative to the housing, thereby positioning the LED at a predetermined position relative to the focal axis of the reflector.

A method for producing a flashlight, comprising the step of:
- assembling a lamp assembly comprising a housing, an LED having a hub, and a
- locating element, comprising the steps of;
- positioning the locating element over the hub of the LED to position the LED relative to the locating element;
- positioning the locating element at a predetermined position relative to the housing;
- connecting the lamp assembly to a flashlight body to position the lamp assembly at a predetermined position relative to the body;
- connecting a reflector to the flashlight body to position the reflector at a predetermined position relative to the lamp assembly, thereby positioning the reflector at a predetermined position relative to the LED.

A flashlight, comprising:
- a housing;
- a reflector having a reflective surface, wherein the reflective surface is disposed about a focal axis;
- an light assembly, comprising:
- an LED comprising a hub;
- and
- a locating element having a first surface configured to cooperate with a surface of the LED hub to position the LED at a predetermined position relative to the locating element;
- wherein the locating element is configured to be positioned over the hub of the LED so that the locating element is positioned between a rearward end of the hub and the reflector;
- wherein the light assembly has a surface configured to cooperate with a second alignment surface to position the light assembly at a predetermined positioned relative to the focal axis of the reflector.
