  • Publication number: 20140177224
    Abstract: A solid-state lighting having an air passage includes a light base, a main body, a collar, a first solid-state lighting module, at least one air passage, and a driving module. The main body has a first end and a second end. The collar is arranged between the light base and the first end of the main body and defines an air flow region air communicable to the atmosphere. The first solid-state lighting module is disposed on a portion of the main body other than the first end. The air passage defines a first opening and second opening thereon for air communication between the solid-state lighting and the atmosphere. The first opening is aligned with the first end. The second opening is arranged correspondingly to be in air communication with the first end. The driving module is arranged in the air passage between the first and the second openings.

  • Publication number: 20140084787
    Abstract: The present invention discloses a power converter contained base, lamp with power converter contained base and lamp with separable power converter contained base. The power converter contained base comprises a first commercial standard base, fundament, cover, power converter and a first connector. The fundament comprises a first opening connected to the commercial standard base and a second opening where the cover disposed. A containing space may be defined by the cover, base and the first commercial standard base. The power converter may be disposed inside the containing space. The first connector may be disposed on the cover or the fundament to be connected with a second connector of a light-emitting member to make the four elements, the first commercial standard base, the power converter, the one of or the combination of two or three of, the fundament, the cover and the connector, and the light-emitting member become electrically connected.

  • Patent number: 7919024
    Abstract: Disclosed are processes for producing monolithic and metal doped monolithic porous carbon disks from prepolymer organic precursors in the powder form composed of either or both polyimide and polybenzimidazole. The powders are consolidated (compressed) into disks and then pyrolyzed to form the desired porous carbon disk. Porous carbon-carbon composite disks are also prepared by adding carbon to the prepolymer organic precursors.
