LUXIM is a privately owned clean tech company based in Sunnyvale, California, which was founded in 2000.LUXIM manufactures a solid-state electrodeless lamp lighting system. LUXIM technology is used in general lighting, entertainment lighting, instrumentation lighting and specialty lighting.Their light-emitting plasma lamp is claimed to be able to operate up to 50% more efficiently than conventional high-intensity discharge lamps while generating the same maintained lumen as a conventional 400-watt system at about half the energy. LUXIM's light-emitting plasma is designed to complement LED. LEP is designed for use in high illuminance applications; LED is more suitable in low illuminance applications.In the general lighting market, LUXIM offers two products: the STA 41-01 and the STA 41-02. Both systems have a CCT in the 5600–5700 range. The STA 41-01 has a CRI of 75 and a life of 50,000 hours, the STA 41-02 has a CRI of 95 and a life of 30,000 hours. These products are used in high-illuminance applications such as streets, parking lots, big-box retailers, distribution centers, parks, and sports lighting applications.LUXIM works with a variety of luminare manufactures across the world. Presently, the following luminaire types are available on the market: Cobra head, shoe-box, high bay, low bay, canopy, aquarium, and architectural. Wikipedia.

An electrodeless plasma lamp is described comprising a lamp body including a solid dielectric material. The lamp includes a bulb received at least partially within an opening in the solid dielectric material and a radio frequency (RF) feed configured to provide power to the solid dielectric material. A conductive material is provided adjacent to the bulb to concentrate the power proximate the bulb. The conductive material may be located below an upper surface of the solid dielectric material. The conductive material may modify at least a portion of an electric field proximate the bulb so that the portion of the electric field is oriented substantially parallel to an upper surface of the lamp body.


In an example embodiment, an electrodeless plasma lamp is provided which comprises a lamp body comprising a dielectric material having a relative permittivity greater than 2, and a bulb adjacent to the lamp body, the bulb containing a fill that forms a plasma when RF power is coupled to the fill from the lamp body. An RF feed is coupled to the lamp body and a radio frequency (RF) power source for coupling power into the lamp body through the RF feed is provided. A shortest distance between an end of the bulb and a point on the RF feed traverses at least one electrically conductive material of the lamp body.


An electrodeless plasma lamp is described that employs acoustic resonance. The plasma lamp includes a metal enclosure having a conductive boundary forming a resonant structure, and a radio frequency (RF) feed to couple RF power from an RF power source into the resonant cavity. A bulb is received at least partially within an opening in the metal enclosure. The bulb contains a fill that forms a light emitting plasma when the power is coupled to the fill. The RF power source includes a controller to modulate the RF power to induce acoustic resonance in the plasma.

An electrodeless plasma lamp and method of generating light are described. The lamp may comprise a lamp body, a source of radio frequency (RF) power and a bulb. The lamp body may comprise a solid dielectric material and at least one conductive element within the solid dielectric material. The source of RF power is configured to provide RF power and an RF feed configured to radiate the RF power from the RF source into the lamp body. The bulb is positioned proximate the lamp body and contains a fill that forms a plasma when the RF power is coupled to the fill from the lamp body. The at least one conductive element is configured to concentrate an electric field proximate the bulb.


A lamp and methods of forming are shown. In one example, a dielectric layer is formed over a gap between conductors in a plasma lamp. Electric arcing is reduced or eliminated, thus allowing tighter gaps and/or higher voltages. In one example a glass frit method is used to apply the dielectric layer. A lamp is shown with a barrier layer that prevents tarnish such as tarnish from sulfur exposure. The barrier layer reduces or prevents degradation of the lamp due to conversion of a conductor material to non-conductive tarnish material.
