Abstract: A lighting system and process for lighting objects particularly art works such as paintings and sculptures, comprising a diffusing film that scatters the light such that the object is illuminated substantially uniformly. The preferred embodiment employs one row of such lighting sources for small objects, and two or more rows for larger objects. The inner row is directed towards the top portion of the object and the outer row is directed towards the bottom portion of the object. The rows need not be placed next to each other. For 3-dimensional objects, one row may be below the object and the other row above to eliminate shadows.

Abstract: A capacitive discharge welding method is used to join firing tips, such as those made from various precious metals, to spark plug electrodes. In one embodiment, charged capacitors or other energy storage devices coupled to welding electrodes quickly release stored energy so that a peak weld power and maximum interface temperature is quickly established, followed by a rapid decline in weld power and interface temperature. The resulting capacitive discharge weld joint may include solidified molten material from both the firing tip and the electrode and possess a number of other desirable qualities.

The lower section includes therein a separation board and two stop boards having a wedge-like shape arranged at each side of the separation board. The pins of the LED extend into the lower section and each positioned against an upright face of the separation board and the stop boards. Metal cores of electrical wires that are partially stripped are received between the stop boards to contact the pins of the LED.

Abstract: A spark plug where a predetermined cross section of a noble metal tip is divided by a vertical line into two half cross sections having a first half cross section and a second half cross section. The first half cross section satisfies h1/t?0.2 and Rw1/Rt1?1.03, and the second half cross section satisfies h2/t?0.2 and Rw2/Rt2?1.03. At a welding interface, an oxidation scale progresses in a direction away from an axis along side surfaces and changes the progressing direction at the end points so as to progress in a direction toward the axis along bottom surfaces. The progress of the oxidation scale is restrained. Since the noble metal tip is held by an engagement portion of a ground electrode, separation of the noble metal tip from the ground electrode 40 can be restrained.

Abstract: Solid state lamps and bulbs comprising different combinations and arrangements of a light source, one or more wavelength conversion materials, regions or layers which are positioned separately or remotely with respect to the light source, and a separate diffuser. These are arranged on a heat sink in a manner that allows for the fabrication of lamps and bulbs that are efficient, reliable and cost effective and can provide an essentially omnidirectional emission pattern, even with a light source comprised of a co-planar arrangement of LEDs. Additionally, this arrangement allows aesthetic masking or concealment of the appearance of the conversion regions or layers when the lamp is not illuminated. Various embodiments of the invention may be used to address many of the difficulties associated with utilizing efficient solid state light sources such as LEDs in the fabrication of lamps or bulbs suitable for direct replacement of traditional incandescent bulbs.

Abstract: A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards a street is beneficial. The source can be coupled to an optic that comprises an inner surface facing the source and an outer surface that is opposite the inner surface. The inner surface can comprise a refractive surface that receives light headed away from the optical axis of the light source, for example opposite the street. The refractive surface can form the received light into a beam. The outer surface of the optic can reflect the beam back across the optical axis, for example so that light headed away from the street is redirected towards the street.
