Abstract: An LED lamp includes a heat dissipator, a socket mounted on one end of the dissipator, a glove formed of a light-transmissive glass or plastic material and attached to the other end of the dissipator, a module substrate on which an LED chip is mounted, the substrate being mounted on the dissipator, the LED chip being covered with the glove, a lighting circuit supplying electric power to the LED chip and mounted in the dissipater, the lighting circuit being connected to the socket, a light-transmissive sheet having a surface formed with a character, a symbol or a pattern, the light-transmissive sheet being fixed in the dissipater or in the glove so as to be located right in front of the LED chip, and a lens located on a top of the glove so that an enlarged image of the character, the symbol or the pattern is projected through the lens.

Abstract: A light fixture device has a light housing to receive a light source therein, a support assembly for supporting the light fixture relative to an anchor location, the support assembly including a post portion for mounting at the anchor location and a body portion, the body portion having a pair of opposed end regions, the post portion including a pair of cavities, each to receive a corresponding end region, the body portion being movable relative to the post portion about a first axis, the body portion and light housing having respective first and second support formations, the light housing being movable relative to the body portion about a second axis, to cause corresponding relative movement between the first and second support formations, the end regions and cavities having complementary third and fourth support formations, wherein relative movement between the body portion and post portion causes a corresponding relative movement between the complementary third and fourth formations.

Abstract: This invention relates to a sound wave generator with a variable effective aperture angle according to the electromagnetic principle for therapeutic applications and particularly for the contactless smashing of a concrement situated in the body of a living being. The sound wave generator includes a flat coil and a metallic diaphragm which is insulated with respect to the flat coil. The flat coil includes three separately activatable and concentrically arranged coil sections. The sum of the areas of the inner coil section and the center coil section is equal to the sum of the areas of the central coil section and the outer coil section. By means of the varying activation of the coil sections, the aperture of the shock wave source can be changed so that the focus geometry and the peak pressures can be varied for different applications, particularly kidney and gallbladder lithotrity.
