Abstract:
An emergency exit sign having a beacon module for indoor positioning and an indoor positioning system using the same are provided. The emergency exit sign includes a power supply unit, an AC/DC converter, an indoor positioning beacon module, an LED lamp, and a charger. The power supply unit receives an input of a power source and supplies the power source. The AC/DC converter converts the power source supplied and supplies a driving power source. The indoor positioning beacon module periodically wireless transmits a beacon signal including a beacon ID through a built-in antenna. The LED lamp is installed within the housing such that the lamp is positioned in rear of the display. When a power source is not supplied from the power supply unit, the charger supplies a driving power source.
Abstract:
An apparatus for generating light may be comprised of a light source with a lens interposed in a light path from the light source. The lens may be comprised of two or more sections wherein at least one section may be comprised of smart glass. Electrical circuitry may be configured to control a transparency state of the smart glass lens sections. Another embodiment may have two reflectors wherein one of the reflectors may be interposed between the light source and the other reflector and may be comprised of smart glass with a transparent state and a reflective state so that two different reflection patterns may be created. A method for illumination wherein at least one area's illumination is controlled by a section of smart glass is also disclosed.
Abstract:
The invention relates to lamps, and particularly to incandescent electric lamps. incandescent electric lamps operating at mains voltage are known for decades and are widespread throughout the world. However, this type of lamp is not power efficient. It is suggested to provide a halogen lamp with a burner surrounded by an outer envelope for an incandescent electric lamp. The appearance of this lamp is identical to known incandescent lamps, but the lamp is more power efficient as it uses the well-known technology of a 12 V halogen lamp.
Abstract:
An incandescent lamp has incorporated a circuit board within a recess in the bulb, wherein the circuit board contains connections and circuitry to control power to the lamp filament while maintaining the attachment of the bulb to the metal base, wherein the completed lamp assembly including the circuit board and the metal base maintains the external physical dimensions to fit into standard incandescent light fixtures. The circuitry on the circuit board contains performance-modifying or performance-monitoring electronic circuitry configured to reflect the restrictive size and thermal considerations while employing designs and manufacturing processes most typically found in such products.

Abstract:
An incandescent lamp has an attachment for connection to a two-wire electrical power line and a bulb containing a radiating element. At least two filaments are housed in the bulb and constitute the radiating element, and circuitry has an input connected to the electrical power line and an output connected to filaments. When a selection signal indicating the desired brightness is passed to circuitry, preferably along the electrical power line, and acts in such a way that circuitry selectively provides a feed to filaments on the basis of the selection signal, a change in brightness is obtained without deterioration of the color characteristics because the filaments operate under their rated operating conditions. The change in brightness will not be continuous, but discrete, but is more than acceptable for domestic requirements even with a small number of filaments.
Abstract:
A new and improved electronic control module (ECM) for controlling lighting functions of an incandescent light bulb and method of manufacturing the ECM. The ECM is installed, such as by press fitting into a dielectric insulating material at the socket end of the bulb, after the high temperature bulb fabrication steps have been completed. In this manner, the solid state and associated circuitry of the electronic control module are not subjected to the high temperature processing used in lamp bulb fabrication. The electronic control module is especially well suited and adapted for integration into the lamp bulb housing and is constructed using a minimum number of reliably constructed and connected electrical components in a hybrid-type circuit module assembly which is economical to manufacture. In one embodiment of the invention, this module is operative by rotational adjustment to provide lighting function control and selectivity for the bulb, and in both embodiments described herein it is in direct contact with the copper center terminal of an adjoining electrical socket. This feature provides excellent heat sinking for and cooling of the module.
Abstract:
An improved 120 Volt/40 Watt incandescent light bulb is adapted to be used in an ordinary Edison-type lamp socket and provides nearly twice the effective Lumen-output as that of an ordinary 120 Volt light bulb of same power rating and same life expectancy.The improved light bulb comprises an electronic inverter-type voltage conditioner that provides a voltage of about 15 Volt RMS magnitude to the filament of a small Tungsten-Halogen lamp. This voltage conditioner is comprised within the bottom part of the light bulb and the Tungsten-Halogen lamp is mounted right above the power conditioner--all within an outer envelope.The improved light bulb has shape and size substantially the same as that of an ordinary household 120 Volt/40 Watt light bulb.Means are provided by which the Lumen output can be manually adjusted over a wide range.In one version, the outer envelope is removable and the small Tungsten-Halogen lamp is replaceable.
Abstract:
An improved incandescent light bulb which is capable of affording increased light efficiency without a resultant increase in either cost or energy consumption. In one embodiment of the bulb, said bulb includes a refractory stiff supporting element, at least one elongated helical resistive filament, two terminals which are each capable of being physically and electrically connected to a different socket and an elongated light transmissive envelope. In another embodiment the bulb additionally includes a reflector bonded to the envelope which reflects light and conducts heat away from said envelope. The stiff supporting element is formed to have a hollow interior. In said hollow interior a magnetizable elongated slug and two holding magnets may be contained. The slug and holding magnets cooperate with a switching means in the interior of the envelope to allow the bulb to selectively emit either a bright or a dim light.
Abstract:
An incandescent lamp possessing a ballast circuit comprising a resistor and capacitor in parallel further includes means for interrupting the connection between the ballast and external contacts provided on the base of the lamp. This interruption occurs upon removal of the lamp from its matching socket to prevent the occurrence of capacitor voltage across the external lamp contacts. The circuit is again closed upon reinsertion of the lamp in the matching socket to permit normal lamp operation.
