Abstract: A luminous electric display unit is disclosed in which glass tubing containing inert gas such as neon is entirely or substantially enclosed within a protective housing, thereby providing protection both for the glass tubing and the public.

Abstract: A luminous electric display unit having glass tubing, filled with an inert gas, fully or partially enclosed within a protective housing, thereby providing protection both for the glass tubing and the public.

Abstract: An improved tubular bulb supporting clip is disclosed. This clip allows for multiple modes of movement between the bulb supporting portion and the stationary stem of the clip. This structure allows for proper support of the tubular bulb even if the bulb has imperfections therein or the clips are not precisely positioned.

Abstract: A low pressure gas discharge lamp has a low profile which includes at least one glass plate with a tube envelope channel having a cover plate covering the evacuation tube which is substantially flush with the plate.

Abstract: Improved structures for housing assemblies for illuminated glass tubing are provided with this invention which comprises a housing assembly with a base section having wall portions forming an elongated channel having an open side; a central section having wall portions forming an elongated channel having an open side; and a light-transmitting cover section having wall portions forming an elongated channel having an open side; the central section secured to the cover section to form a light unit, the light unit being shorter than the base section; an elongated support plate for glass tubing, the wall portions of the central section including means adjacent the open side of the central section channel for supportably receiving the support plate in the channel; and the wall portions of the base section and the central section including means for securing the central section to the base section in snap-fit relation to close said open sides of said channels; whereby the longitudinal position of the light unit on t

Abstract: A longitudinally curved, modular housing assembly for the protective support of illuminated glass tubing, such as neon lights, characterized by interconnected base, central, and cover sections which are all curved and have equal radii of curvature. The configuration of the housing assembly is such that it permits combination thereof with other, similar, housing assemblies to provide continuous lighting systems having various shapes and outlines. The housing assembly preferably contains a transformer and wiring for connection to a power source.

Abstract: A low pressure gas discharge lamp has a low profile which includes at least one glass plate with a tube envelope channel having a cover plate covering the evacuation tube which is substantially flush with the plate.

Abstract: An electric luminous display unit for conveying visual information including a housing comprising an opaque front face portion of substantially rigid molded plastic, an elongated groove in the front face portion of the housing, inert gas-containing glass tubing located in the groove and extending therealong, and electrical means located behind the front face portion of the housing and electrically connected to ends of the glass tubing for supplying electrical energy to illuminate the same. In one embodiment, an edge-lighted board is described for receiving written information thereon.

Abstract: A housing assembly for protective support of illuminated glass tubing of the neon tube type comprising a base section, a central section, and a transparent cover section, each having wall portions forming an open sided elongated channel, a support plate mounted in the central section, elongated glass tubing disposed in the cover section and supportably mounted on the support plate in fastening clips, the base, central, and cover sections being formed of resiliently deformable material, such as plastic, and being assembled in snap-fit relation with each other to enclose the open sides of the channels. End caps enclose ends of the cover and central channels and protect the glass tubing and an electrical transformer and wiring disposed therein against weather.
