Stranded outer lead wire assembly for quartz pinch seals
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 glare measuring system is configured to have an imaging camera which is supported to be rotatable within a horizontal plane, and a processing device which calculates equivalent veiling luminance on the basis of a pickup image of the imaging camera and calculates the value of a glare rating GR on the basis of the equivalent veiling luminance. The imaging camera has a super-wide-angle lens mounted thereon, and picks up an image in a position which is rotated within the horizontal plane by every angle corresponding to the angle of view α of the super-wide-angle.
