  • Publication number: 20180087753
    Abstract: A light fixture has two reflective blades that are adjustable. Adjusting the setting on the reflective blades allows for the controlling of how widely or narrowly the light will be focused from the light fixture. The reflective blades reside within the light fixture, and are positioned on either side of the lamp. The reflective blades attach to the light fixture via a fastener on two ends of the light fixture's casing, while alloblade each reflective blade to pivot along the two fasteners. The reflective blades are pivoted along the fasteners, and are held stationary through the use of a spring loaded knob that has a rounded base for embedding itself with in receptacle on the light fixture's casing.

  • Patent number: 9583329
    Abstract: Disclosed herein is an adjustable induction lamp adapter that is also extendable. The adjustable induction lamp adapter attaches to an induction lamp by clamping onto an induction lamp bar. The clamping is achieved through the use of a removable end cap at the base of the adjustable induction lamp adapter, wherein the end cap has a cutout and screw to hold the induction lamp bar in place. The adjustable induction lamp adapter is designed to also be able to extend in length by attaching one or more extension adapters.

  • Patent number: 9053920
    Abstract: An internal induction lamp with a glass envelope bulb assembly and an inductor shaft assembly. The glass envelope bulb assembly is a hollow glass envelope bulb with a mercury amalgam stem protruding downwards from the bottom of the hollow glass envelope bulb. The mercury amalgam stem is fragile, and protected by a stem protector. The inductor shaft assembly, which inserts into the glass envelope bulb assembly accommodates the protrusion of the mercury amalgam stem along with the stem protector. The inductor shaft assembly and envelope bulb assembly may attach via a threaded ring connector. The inductor shaft assembly may have a heat sink, and a gap within the heat sink to accommodate placement of the stem protector within this gap.

  • Patent number: 9030088
    Abstract: A fluorescent lamp has an amalgam chamber that is in communication with the interior of the lamp through an exhaust tube. The amalgam chamber is constructed as a three-way junction with the exhaust tube and is formed at a supplementary angle of 180 degree or less with respect to the exhaust tube. The construction of the chamber utilizes the force of gravity to keep the amalgam away from the opening of the exhaust tube leading to the interior of the lamp. The amalgam chamber is capable of effectively retaining the amalgam within the chamber and preventing it from penetrating into the interior of the lamp regardless of mounting direction.

  • Publication number: 20130294098
    Abstract: Disclosed herein is a lamp socket extender, generally comprising a base section, an extendable body, and a head section. The base section connects to a light socket, such as an Edison style light socket. The head section attaches to a lamp adapter, which holds a lamp. The extendable body is capable of extending to create more or less distance between the head section and the base section. In a preferred embodiment, the extendable body is comprised of a core covering and a telescopic covering. There may be a wiring harness utilized to more easily attach and detach the wiring from the lamp to the lamp socket extender.
