    Abstract: An assembly (10) for a lamp. The assembly 10 includes a light source (12) having a center chamber (14) and opposite ends (16, 18), arrayed along a longitudinal axis (19). The ends (16, 18) are cylindrical in cross-section. A tubular shroud (20) surrounds the light source (12) and is coaxial with the longitudinal axis (19). The light source (12) is mounted within the shroud (20) by spring clips (26) one of which is mounted at either end of the shroud. The spring clips each include a base (28) lying in a first plane and having an aperture (30), for example, a star-shaped aperture, centrally located in the base. The apertures (30) in the two spring clips frictionally engage one of the ends (16, 18) of the light source (12).

  • Patent number: 6822380
    Abstract: In an electron emitter based on Metal-Insulator-Semiconductor or Metal-Insulator-Metal emitters, field emission structures are enclosed within the emitter structure. The electron emitter may include a conductive substrate and an electron supply layer formed on the conductive substrate. The electron supply layer, for example undoped polysilicon, has protrusions formed on its surface. The sharpness and density of protrusions may be controlled. Above the electron supply layer and the protrusions, an insulator may be formed thereby enclosing the protrusions. A top conductive layer may be formed above the insulator. The enclosed protrusions are relatively insensitive to vacuum contamination. The thinness of the insulator allows high intensity electric fields at the protrusions to be generated with low applied voltage. Field-enhanced injection of electrons into the insulator and thence through the top conductive layer results. Furthermore, electron beam dispersion and divergence are minimized.

  • Patent number: 6815883
    Abstract: A cold cathode fluorescent lamp (CCFL) comprises an inner fluorescent tube and an outer glass tube which is sheathed on the outside of said inner tube, characterized in that said inner fluorescent tube and said outer glass tube is separately disposed, and there is a space therebetween. Said CCFL further comprises electrodes sealed at the ends of said inner fluorescent tube and said outer glass tube. The CCFL of the present invention has a double-tube construction, as a result, the inner fluorescent tube is not so much affected by a change in the environmental temperature. Further, the inner fluorescent tube and the outer glass tube are separately disposed so that the end of the inner fluorescent tube and the end of the outer glass tube are not integrally joined, so that a rate of the breakage caused by the temperature difference between two ends is dramatically reduced.
