  • Patent number: 7394189
    Abstract: An objective is to provide a compact self-ballasted fluorescent lamp which can reduce occurrence of a short circuit without protecting lead wires extending from each end portion of a spiral arc tube. To achieve the objective, a pair of connection pins is provided on a circuit board of the compact self-ballasted fluorescent lamp, near a periphery of the circuit board so as to oppose another pair of connection pins formed near the periphery. In this way, the pairs of connection pins can be respectively provided directly above the end portions of the spiral arc tube. Thus, lead wires extending from each of the end portions can be connected to a corresponding one of the pairs of connection pins with a relatively short distance. This prevents the lead wires from being in contact with the circuit board, thereby reducing occurrence of a short circuit.

  • Patent number: 6894429
    Abstract: In a discharge lamp device, the arc tube body is configured by welding and integrating shroud glass with an arc tube so as to enclose a discharging portion, and a rearward elongating portion of the arc tube that elongates in the rear of the shroud glass is inserted and held into an opening of an insulating plug which is made of synthetic resin. A UV blocking film is formed on the outer surface of the rearward elongating portion of the arc tube. UV components of leakage light from the rearward elongating portion are cut off, and the amount of ultraviolet rays to which the resin layer in the opening is exposed is reduced. The UV blocking film is in the opening, and hence cannot be seen through a front lens.

    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). Each of the spring clips (26) has a U-shaped projection (32) at and end (33) of the base (26). The U-shaped projection comprises first and second upstanding walls (34, 36) joined by a first lip (38) that extends in a second plane and is fitted over the wall of the shroud (20).

  • Patent number: 6836058
    Abstract: A low pressure gas discharge lamp with a tubular discharge vessel is provided with two separate capacitive coupling members at its ends, the discharge vessel having a small inner diameter of preferably less than 5 mm. Each coupling member has a cylindrical tube of dielectric material. The electrical connection to the coupling members is realized by pressing a spring element having an inner diameter smaller than the outer diameter of the cylindrical tube around this tube. The spring element tightly surrounds a metal body on the cylindrical tube while forming a number of contact points.
