Patent Images
1. A waterproof light assembly for directing a beam of light comprising:
- a lamp-reflector assembly containing an electrically powered lamp housed within a reflector;
a translucent lens; and
a flexible enclosure extending between a front opening and a rear opening;
wherein the front opening in the flexible enclosure surrounds the lamp reflector assembly and at least a portion of the lens and the rear opening surrounds at least a portion of a power cord passing therethrough and interconnected with the lamp, the front and rear openings being adapted to form a seal about the lens and the power cord respectively.

Abstract
A light assembly for providing a directed beam of light. The light assembly includes a specially configured lamp-reflector assembly which incorporates a high output lamp. The lamp-reflector assembly also incorporates a multi-faceted reflector for directing the beam of light within a restricted cone angle as it exits the light assembly. The lamp-reflector is housed in a flexible enclosure surrounding a translucent lens at one end and a power cord exiting the opposing end. The flexible enclosure is adapted for waterproof applications.

17. A light assembly directing a light beam comprising:
-
an electrically powered lamp having an axially-aligned filament; a reflector housing the lamp and having an inside surface configured with at least 32 radial lanes of facets, each lane having at least 12 facets, at least 6 of said at least 12 facets being oriented in a direction generally facing the light beam emanating from the lamp and at least 6 of said at least 12 facets being oriented in a direction nearly parallel with the axis of the light beam emanating from the lamp; a translucent lens; and a flexible enclosure extending between a front opening and a rear opening; wherein the flexible enclosure houses the lamp and the reflector and surrounds a portion of the translucent lens. - View Dependent Claims (18, 19, 20, 21)

22. A light assembly directing a light beam comprising:
-
an electrically powered lamp having an axially aligned filament; and a glass reflector housing the lamp and having a generally parabolic shape with an inside reflective surface configured with a multiple number of facets arranged in radial lanes; wherein a plurality of radial lanes of a first type are between a plurality of radial lanes of a second type so as to provide the reflector with increased mechanical strength and more uniform average thickness of the glass material; wherein the light from the reflector is focused by said facets to provide an output light beam having a total included cone angle of less than 60°

24. A light assembly for directing a light beam comprising:
-
an electrically powered lamp having an axially aligned filament, wherein the filament has a bottom closest to the base of the lamp and a top distant from the base; a reflector assembly, housing the lamp and having an inside surface configured with a multiple number of facets, the reflector having a top at the reflector opening and an apex, wherein the top of the filament is no more than about two-thirds the distance from the apex to the top of the reflector and the ratio of the reflector diameter at its opening to the height of the reflector measured from the reflector apex to the top is 1.67 or less, wherein the light from the reflector is focused by said facets to provide an output light beam having a total included cone angle of less than about 80°
