摘要： An overhead projection system which includes a planar lens assembly having two concentrically-oriented condensing lenses. The outer lens has a greater focal length than the inner lens to receive light reflected from the system's reflector while the inner condensing lens receives direct lighting from the system's light source. Accordingly, the inner lens images the light source at the projection lens of the system and the outer lens images the virtual image of the light source.

摘要： A lamp assembly includes a reflector having a concave reflecting surface and an axis of rotation, and a light source including a filament mounted at or near a focal point of the reflecting surface. The filament has a length to diameter ratio of 6:1 or greater. The reflecting surface is formed as a multiplicity of reflecting facets. The facets on at least 50% of the reflecting surface have dimensions and curvatures selected to produce a light pattern wherein a ratio of filament width spread to filament length spread produced by the facets is at least 2:1. Preferably, the facets are arranged in axially adjacent rings. The facet rings can be successively offset in a rotational direction so as to reduce circumferential variations in the light pattern.

摘要： A miniature, low-wattage fluorescent lamp includes a double-bore inner capillary tube having a pair of ends and a convoluted shape. The inner capillary tube is comprised of a vitreous material (e.g., quartz) which is capable of transmitting ultraviolet radiation. A pair of electrodes (e.g., mercury pool) is located at one end of the inner capillary tube and disposed within respective bores. An ionizable medium is enclosed within the inner capillary tube and includes an inert starting gas and a quantity of mercury. When energized, the ionizable medium generates an arc discharge between the electrodes consisting of ultraviolet radiation. A phosphor coating responsive to the ultraviolet radiation is disposed on an outer surface of the inner capillary tube and remote from the arc discharge. An outer jacket of vitreous material surrounds the inner capillary tube and contains an inert gas at a predetermined pressure.

摘要： A source of red light includes a double-bore capillary tube having a pair of ends and a convoluted shape. A pair of electrodes is located at one end of the capillary tube and disposed within respective bores. An ionizable medium is enclosed within the capillary tube and includes neon at a pressure from about 300 to 600 torr. When energized, the ionizable medium generates an arc discharge between the electrodes consisting primarily of radiation in the range of from 590 to 670 nanometers. An outer jacket of vitreous material may surround the capillary tube and contain an inert gas (e.g., nitrogen) at a predetermined pressure.
