Flashlight housing
First Claim
1. A flashlight assembly comprising:
- a portable flashlight housing;
a lighting assembly including a lighting element and a heat sink wherein heat generated by said lighting element is absorbed by said heat sink, said lighting assembly disposed within said flashlight housing; and
a power source fully contained within said flashlight housing for selectively energizing said lighting assembly wherein said lighting assembly generates heat and light when energized,wherein said flashlight housing further includes at least one opening, said opening positioned adjacent said heat sink whereby said heat from said energized lighting assembly is transferred via said heat sink from an interior of the flashlight housing to a surrounding environment through said at least one opening in said flashlight housing.

Abstract
The present invention provides a lighting assembly that incorporates a high intensity LED package into an integral housing for further incorporation into other useful lighting devices. The present invention primarily includes three housing components, namely an inner mounting die, an outer enclosure and an outer housing that cooperate to enhance the heat management of the overall assembly. The inner and outer components cooperate to retain the LED package, provide electrical and control connections, provide integral heat sink capacity and includes an integrated reflector cup. Surface area enhancements on the outer surface of the outer enclosure are aligned with openings in the outer housing to allow efficient air flow around the LED assembly to enhance cooling. In this manner, high intensity LED packages can be incorporated into lighting assemblies with reduced risk of overheating and malfunction.

16. A flashlight assembly comprising:
-
a housing; a lighting assembly disposed within said housing, said lighting assembly including a light emitting diode and a heat sink; and a power source for selectively energizing said light emitting diode said light emitting diode generates heat and light when energized, said heat being transferred from said light emitting diode into said heat sink, wherein said housing further includes at least two openings adjacent said heat sink whereby said heat from said energized light emitting diode is further transferred from said heat sink disposed within said housing and ambient air enters a first opening, circulates around said heat sink to absorb said heat and exits a second opening thereby dissipating said heat to a surrounding environment. - View Dependent Claims (17, 18, 19, 20, 21)
