1. A hand-held high-intensity ultraviolet inspection lamp comprising:
- a) a substantially-straight handle having two ends, a grip area, and a longitudinal axis;
b) a bulb housing comprising an enclosed chamber attached to one end of the handle, the bulb housing also having a longitudinal axis, the handle and the bulb housing being in a fixed in-line attachment such that the axis of the housing is substantially aligned with the axis of the handle, and the bulb housing comprising a conic section dish made of a plastic material;
c) a high-intensity light bulb within the bulb housing;
d) an aperture in the bulb housing located along the longitudinal axis of the housing at the end of the housing opposite the handle;
e) a focusing reflector inside the bulb housing;
f) an ultraviolet light filter positioned to block the emission of visible light from the lamp;
g) the handle having internally mounted an electrical socket adapted to receive the light bulb such that the bulb extends into the bulb housing substantially at the focus of the reflector; and
h) means for isolating heat generated by the bulb and filter from conduction to the grip area of the handle.

Abstract
A compact hand-held high intensity ultraviolet inspection lamp having a straight handle aligned with beam direction includes a high-intensity light bulb enclosed within a bulb housing, a light-emitting aperture at the end of the bulb housing away from the handle, and an ultraviolet light filter in alignment with the aperture to absorb substantially all light emitted from the bulb at frequencies outside of the ultraviolet spectrum and to transmit the unabsorbed ultraviolet light. Three embodiments of such lamp are disclosed herein.
