A high output lamp is made with LED filaments (i.e., LED chips mounted on a long narrow substrate and encapsulated in silicone). High output is enabled by structurally minimizing thermal resistance between filaments and bulb. The bulb is generally tubular and contains a mount structure with longitudinally extended LED filaments electrically and mechanically connected between ring or disc shaped end connectors, and spaced apart around the structure's perimeter. An outer surface of the LED filaments defines a mount structure perimeter that is held adjacent to an inner surface of the bulb, separated by a total diameter difference gap of substantially zero to three millimeters maximum. End connectors may have a cut out portion enabling resiliently compressible diameter. The bulb may be filled with pure helium, or pure hydrogen, or a mixture of the two. A contaminant cleaner inside the bulb may be an oxygen dispenser.

An aiming device configured for easily removable attachment to a light projecting luminaire. The device has a body with attachment members that are configured to fit a specific luminaire that has corresponding attachment receiving features, and is further configured with clamps for mounting a light source outputting a high intensity collimated visible light aiming beam such that, when the device is removably attached to the luminaire (i.e., latched in place) the laser is prepositioned to direct the laser beam parallel to a center axis of the luminaire's light output beam. Ideally the luminaire has preexisting features that can be utilized as the attachment receiving features for corresponding attachment members of a suitably configured aiming device.

LED lamp

A glass jacketed led lamp is characterized by a prismatic LED module positioned coaxial to the axis of a cylindrical glass jacket having an inside diameter D, wherein the LED module comprises: a prismatic LED carrier structure having N longitudinal sides, and LEDs that are operationally mounted on at least one of the N sides; wherein: the carrier structure was formed by folding a single metal core printed circuit board (MCPCB) into a convex prismatic polyhedron; the prism cross section is an irregular and incomplete polygon such that the N sides are bounded by N+1 longitudinal fold edges, wherein a first edge and the (N+1)th edge are back edges that are spaced apart by a first separation GAP

A stranded outer lead wire assembly for a quartz pinch sealed lamp. The stranded outer lead wire assembly is a butt welded connection of a refractory metal outer pinch lead (e.g., molybdenum solid wire) and a stranded soft metal lead wire (e.g., nickel wire strands twisted together). The assembly is prefabricated and then welded to sealing foil to make a four part foliated lead wire assembly for pinch sealing in the quartz outer jacket. The foliated lead wire assembly and a quartz envelope lamp utilizing the stranded outer lead wire assembly are also claimed. The sealing machine is adapted to protect the stranded outer lead assembly with a water cooled sleeve. In an embodiment, the outer end of the stranded lead is fused to prevent fraying.

An LED lamp is enhanced by adding an integral control receptacle, wherein a frame structure of the lamp having a horizontal top surface is adapted by attaching a photocontrol receptacle on the top surface and wiring it for powering some pins of the receptacle and for connecting some pins for controlling functions of the LED lamp. The control is provided by plugging a suitable controller into the receptacle. Advantageously, a metal plate is attached between the receptacle and the lamp frame, thereby enhancing performance in ways that include heat sinking, blocking uplight, reflecting added light down and outward. Additional lighting effects are derived from optionally shaping the plate, providing different surfaces on it, and/or attaching more LEDs on it.

A lamp assembly and a method for securing a base on the lamp that electrically connect a side lead wire to the base shell and that also secure the base to the lamp without using either solder or adhesive. Welding efficiency is optimized for the side lead wire to base shell connection. A metal screw base having base screw threads is screwed onto an outer jacket having a threaded seal with seal screw threads and with at least one lead wire extending out of a bottom of the seal being electrically and mechanically connected to a flag assembly being at least a wire in a close-fitted electrically nonconductive sleeve. A groove is formed across the seal screw threads, the groove being dimensioned to closely fit around the flag assembly; and the flag assembly being positioned in the groove such that an inner end of the flag assembly is electrically connected to the lead wire, and an outer, flag, end of the flag assembly is bent over a lip of the base and welded to an outside surface of the base, with the weld preferably being near to the lip.
