  • Patent number: 11966033
    Abstract: A system and method of generating white light for a projection system in a compact form factor using laser diodes, a reflection system, and a phosphor target. Light emitted from the laser diodes can be directed towards a region of the phosphor target, where the phosphor target is excited and emits light in a desired spectrum in all directions. Some emitted light is collected by a collection lens. The emitted light collected by the collection lens can be combined with light from the original laser diodes to create white light for use in the projection system. Light emitted in a direction away from the collection lens can be redirected to the collection lens by the reflection system that employs a curved reflector on one side of the phosphor target and a flat reflector on the opposite side of the phosphor target.

  • Publication number: 20050148270
    Abstract: A discharge device is described that contains an anode, a cathode, and an insulating layer disposed between the anode and the cathode. A cavity is extends entirely through at least one of the anode or cathode and penetrates the dielectric layer. At least one of the anode or cathode may include a screen or the dielectric layer may have a plurality of films with at least two different dielectric constants. The voltage differences between the anode and cathode in each of multiple devices electrically connected together may be limited.

  • Patent number: 6563257
    Abstract: A discharge device of the invention includes multiple bonded ceramic layers with electrodes formed between the layers. It can be combined with the various MCIC technologies to produce myriad useful devices. Contacts are made to the electrodes, which may be grouped in different arrangements. The electrodes contact a hole through some or all of the ceramic layers to define a discharge cavity. Different groupings of the electrodes will produce different types of discharge. Alternating the electrodes in interdigitated pairs permits an arbitrary extension of the discharge cavity length. Having consecutive anodes or cathodes permits formation of regions where electrons may cool. Another device of the invention includes a multilayer ceramic structure having a hole formed in a least one outer layer through an electrode on the outer side of the layer and in contact with an electrode between two layers. A contact is formed to the electrode between layers through any remaining layers in the multilayer ceramic structure.
