Abstract:
A robust LED lamp may be assembly by forming a heat sinking sandwich with two metal heat sinks positioned around the circuit board and pinned together a heat conductive element. The assembly is positioned by pressing it into a base providing electrical connections. The robust assembly is rapidly assembled, thermally effective in draining or spreading heat from the circuit board and is readily adaptable to a variety of applications lighting. The heat sink may be decorated, colored or otherwise esthetically enhanced for consumer appreciation.
Abstract:
The light bulb contains a transparent body member and a contact member at an end of the body member that could be screwed into a conventional light bulb socket for establishing electrical connections. The light bulb also contains at least a disc and a supporting pole. A number of LEDs are back-to-back configured along the circumference of each disc with appropriate distance therebetween. The discs are threaded by the supporting pole with appropriate spacing therebetween. Each disc also contains a circuit for driving the LEDs that is connected to the contact member's electrical connections via an appropriate conduction mechanism in the supporting pole.

In the electrodeless lighting system according to the present invention, a position of a stud mounted inside the resonator can be changed, the size of the stud mounted inside the resonator can be changed, or the number of studs can be changed thereby changing distribution of intensity of the electromagnetic field distributed inside the resonator, so that one of the luminescent materials within the first and second bulbs selectively emits light according to the taste of a user or a season. Accordingly, in the present invention, desired light of various kinds can be emitted.
Abstract:
A high pressure gas discharge lamp includes first and second discharge devices electrically connected in series within an outer envelope. The discharge devices each include a discharge vessel enclosing a discharge space with an ionizable fill and first and second discharge electrode assemblies. The first discharge electrode assemblies of the discharge devices are connected so as to receive a starting pulse and lamp operating voltage. Each discharge vessel includes a first wall portion spaced from the first discharge electrode assembly and defining an ionizable gap therebetween. A conductive element bridges the discharge devices at the first wall portions and capacitively couples the first discharge electrode assemblies to induce ionization in one of the discharge devices in the ionizable gap between the first wall portion and first discharge electrode assembly.
Abstract:
Multiple concentric, triangular cross-sectioned fluorescent lamp tubes, located substantially in the same plane with respect to each other, are utilized in appropriate assemblies for: 1) a direct screw-in replacement for reflective incandescent lamps and; 2) recessed ceiling fixtures that are typically hardwired. The inherent triangular geometries of the concentric, substantially same plane lamps create mutually benefiting reflecting surfaces to maximize the net light output. The triangular geometry enables light from two sides of the fluorescent tubing to be efficiently cast if desired (or muted by absorbent housing wall if desired). The remaining side, or base, of each triangular tube produces light that is redirected by opposing, intersecting, coaxial, conical reflectors arranged to direct the light through the unobstructed center of the concentric tubing arrangement. A transparent collimating structure adjacent to the triangular tub bases is used to enhance control of the light emanating from the base. The arrangement is incorporated in a single assembly with an Edison screw-in base and as lamp assemblies for use in hardwired fixtures.
Abstract:
A high pressure discharge lamp includes a pair of arc tubes connected electrically in parallel within an outer envelope, which includes a lamp stem having a pair of stem conductors entering the lamp envelope in a common plane. The arc tubes include conductive feed-throughs at each end thereof. A lamp frame supports the arc tubes in a plane parallel with the stem conductors and is welded directly to each of the feed-throughs with all welds in a common plane with the welds between the frame and the stem conductors. The frame includes a resiliently deformable transverse member which allows for independent changes in length of the arc tubes during lamp operation due to thermal expansion/contraction. The frame is free of slip fit connections with the feed-throughs and free of additional conductive straps connected to the feed-throughs.
