A lamp system (36) includes an electric lamp (10) having an internal reflector (24) disposed within an envelope (12) for redirecting light emitted from a filament (14) away from a base (20) of the lamp (10) and onto the filament (14). Utilizing the internal reflector (24) in this manner improves the efficiency and increases the life expectancy of the lamp (10) by reducing the electrical current required to maintain an optimum temperature of the filament (14) for producing light. Additionally, the ability to place the lamp filament (14) in close proximity to the base of an external reflector (38) alters the focal point of a lamp system (36) incorporating the lamp (10), thereby allowing use of external reflectors (38) of lesser bulk and diameter without sacrificing efficiency and intensity of the light beam emitted therefrom. |
