摘要:
A device for holding a compact fluorescent lamp in a light fixture with a socket 10 and a lamp base is shown and described. The bayonet-type fixing of the lamp base in a socket 10 is effected by means of a plug-and-rotate motion. In order to give manufacturers of light fixtures the possibility of manufacturing light fixtures for lamps with a predetermined or maximally admissible lamp wattage, the invention proposes a key system with seven key pairs. Each key pair comprises a lamp key and a socket key and characterizes a predetermined lamp wattage. Concretely speaking, the socket key is a lug arranged in a hole and the lamp key is a plug corresponding to the socket hole with a outwardly open cutout. In addition, a key system for making predetermined lamp types recognizable is described.

A phosphor blend for a compact fluorescent lamp is described wherein the phosphor blend comprises a green-emitting Tb3+ phosphor, a Y2O3:Eu3+ phosphor, a Sr6BP5O20:Eu2+ phosphor, a Mg4GeO5.5F:Mn4+ phosphor, and optionally a BaMgAl11O17:Eu2+ phosphor, wherein the blend contains from 1% to 20% by weight of the Sr6BP5O20:Eu2+hosphor and from 5% to 30% by weight of the Mg4GeO5.5F:Mn4+phosphor. A compact fluorescent lamp having a phosphor coating containing the phosphor blend produces a light that is perceived as more pleasing than the light produced by standard compact fluorescent lamps.

摘要:
A subassembly (10) for a lamp base, the subassembly (10) has an outer (12) housing having a circumferential wall (14) and a top (16) closing one end (18) of the outer housing (12); at least one lamp receiving aperture (20) in the top (16); and an inner housing (22) contiguous with an entire inside surface (24) of the outer housing (12), the outer housing (12) being a metallic material and the inner housing (22) comprising a plastic material.
摘要:
A lamp base has a projection that carries lamp contacts and has an outer surface formed with retaining formations arrayed with irregular spacing. A socket forms a recess into which the projection can be inserted with play and apertures provided with contacts engageable with the lamp contacts. Retaining formations in the socket fit with the lamp-base retaining formations in only one defined angular alignment of the lamp base and the socket. The projection has a central plug projecting toward the socket and forming a lamp key coded for a predetermined lamp wattage. The socket has a hole corresponding to the plug and itself forming a socket key coded for the maximally admissible lamp wattage for the socket. The lamp base only fits into the socket when the lamp wattage indicated by the lamp key does not exceed the maximally admissible lamp wattage defined by the socket key.
摘要:
A special purpose lamp (12) (SPL) and a socket (14) therefore, the SPL (12) having a light source (16), a base (18) connected to the light source. The base (18) has electrical connectors (20) and a negative key (22). The socket (14) includes a pocket (23) for receiving the base (18), receptors (24) for receiving the electrical connectors (20) and a positive keyway (26) for receiving the negative key (22). In a preferred embodiment, the base (18) has a portion (18a) that is substantially rectangular in cross-section and the negative key (22) is associated with a corner (18b) of the portion (18a). Lamps so constructed can fit older sockets while older lamps will not fit the sockets of the invention.
