Abstract:
A lamp is provided which is suitable for use in low-profile applications. The lamp includes a light source and a lens. The lens includes a first surface opposite a second surface, where the second surface includes an injection surface and the first surface includes a multi-faceted optical element converging towards the injection surface. The light source injects light into the lens via the injection surface and the light refracts through the first surface while total internally reflecting off the first surface and the second surface toward the periphery of the lens.
Abstract:
In accordance with one aspect of the present disclosure, a waterproof LED lamp is disclosed. The waterproof LED lamp includes a housing having one or more LEDs disposed within said housing. The housing comprises a housing base including a body with a first opening, the first opening having an edge surrounded by a first sealing portion. The housing further includes an optical cover comprising a shell having a second opening, the second opening having a border surrounded by a second sealing portion. The second sealing portion is configured to be removably inserted into the first sealing portion, forming a water-tight seal between the housing base and the optical cover.
Abstract:
Drivers and ballast circuits are presented having a boost converter with a triac compatibility circuit providing regulated current load to accommodate phase-cutting triac circuit holding current requirements, including auto switching driver circuit with overvoltage protection and an auto leveling circuit to regulate against thermal and load fluctuations.
Abstract:
A lamp assembly provides both instant light through use of an incandescent/ halogen lamp source and an energy saving type light provided by a compact fluorescent lamp source. Both light sources are fixed within the assembly by a fixing mechanism that spaces the lights sources from each other such that heat from one source does not negatively affect the second light source or any other portion of the assembly.
Abstract:
A method and apparatus for measuring runout of using a distance measuring sensor mounted to a rotor and targeted at a circular wall, an electronic inclinometer mounted within a diameter of a hub of the rotor, and a microcontroller in data communication with the inclinometer and the sensor. A computer may be operably connected to the microcontroller and used for programming the microcontroller. A rotatable fixture including a bar mounted to the hub may be used to mount the sensor to a distal end of the bar and the microcontroller and the inclinometer may be mounted on the bar. Runout of a fan shroud circumscribing fan blades of an engine rotor may be measured with the apparatus and method and the bar angularly located between a pair of adjacent blades. The computer may be used to gather data from inclinometer and sensor and calculate runout.
Abstract:
Disclosed herein are mercury free ceramic metal halide high intensity discharge lamps of specified arc tube geometry and composition of ionizable fill. Embodiments herein generally employ a discharge vessel formed of a ceramic material having an aspect ratio satisfied by 1
Abstract:
A low pressure discharge lamp comprises a phosphor composition configured to provide a total light emission having characteristics within specified parameters, including color point above or substantially on the Planckian locus in the CIE standard chromaticity diagram; CCT of from about 2500 kelvin to about 3600 kelvin; general color rendering index Ra(8) of at least about 80; and special color rendering index R'a(14) of from about 72 to about 87. These novel lamps result in incandescent-like color quality while also having favorable efficacy. Also disclosed are phosphor blends which enable the achievement of such lamps.
Abstract:
The present application provides a solids feeder in communication with a flow of solids and a flow of a conveying fluid. The solids feeder may include an outlet channel with the flow of the solids therein and a discharge port in communication with the outlet channel. The discharge port further may include an inlet in communication with the flow of the conveying fluid and a flow channel. The flow channel may include a reduced cross-sectional area about the outlet channel as compared to the inlet.
Abstract:
A filament coil (100) for an incandescent lamp assembly is provided. The filament coil includes a helical winding extending generally along a longitudinal axis (102) between a first end (104) and a second end (106). The filament coil further includes a winding having a first pitch ratio h/d at the first and second ends, and a different, second pitch ratio along an intermediate portion (108) located between the first and second ends.
Abstract:
A ballast circuit (6) comprises a rectifier circuit (8) and dual starting circuits (11, 13) that ensure ballast startup and lamp ignition regardless of input waveform half cycle. The first starting circuit comprises resonant circuit (10), and the second starting circuit includes a resistor (11). The resistor (11 ) comprising the second startup circuit provides a bias resistance to the second switches (72) to ensure ballast startup when an oscillating input waveform is in a negative phase.
