Definitions

  • THIS INVENTION in its various aspects, relates to the construction of a lamp providing a high light intensity in a required direction and, more specifically but not exclusively, is concerned with a high-pressure discharge lamp or an incandescent lamp.
  • Ptchelin United States patent specification No. 5,051 ,755 describes a lamp having an elongated, convex, glass envelope which is non-circular in cross-section and is provided at one end with an electrical terminal connector.
  • An illumination assembly inside the lamp is provided with an intense light source of rod-like shape which extends lengthwise along a predetermined optical axis of the lamp.
  • the lamp envelope has its inside surface partly-coated with a highly reflective layer or film.
  • the envelope may be evacuated, or may be filled with an inert gas.
  • the interior surface profile of the lamp is so shaped that the reflected light follows a path which largely misses the optical axis with which the light rod is aligned, so that the light rod is not subjected to excessive heating. Its life time is therefore prolonged.
  • a lamp will be referred to hereafter as being "of the type described".
  • the pattern of the radiation produced by a lamp of the type described with regard to the consistency of its quality and the shape of the radiated pattern are determined by the accuracy of the positioning of the components of the illumination assembly inside the lamp envelope.
  • the consistency and quality of the light pattern falling on the street depends not only on the positioning of the light assembly within the lamp, but also on the angular positioning of a socket provided for the lamp inside the luminaire OBJECT OF THE INVENTION
  • An object of this invention is to provide an improved lamp.
  • a high intensity directional lamp has a terminal connection attached to a glass envelope and which includes inner and outer concentrically-arranged and electrically interconnected sleeves which are relatively rotatable without axial displacement with respect to one another, stop means for limiting rotation of the outer sleeve in one direction with respect to the inner sleeve, and electrically-conductive means providing an electrical connection between a light-generating source forming part of an illumination assembly within the lamp, and two mutually-insulated terminals provided on the terminal connection; in which lamp said stop means comprises a one-way ratcheting mechanism which permits unlimited relative rotation of the outer sleeve in one direction with respect to the inner sleeve, but which limits rotation of the outer sleeve when turned in the reverse direction with respect to the inner sleeve.
  • the one-way ratcheting mechanism allows the lamp to be screwed into its socket in a luminaire and then, by continued rotation of the lamp in the same direction, the pattern of illumination of the lamp can be turned to a required angular position. This is achieved without risk of the terminal connection being slightly unscrewed from its operating position and which would otherwise cause the lamp to make intermittent electrical contact with tne socket and to wobble in the socket. Removal of the lamp from the socket is not impaired by the ratcheting mechanism because it only allows indefinite rotation of the outer sleeve with respect to the inner sleeve, in one direction. If the lamp is to be removed from the socket, it is turned in the reverse direction and the one-way ratcheting means then act as an abutment or stop means so that the two sleeves turn together in the reverse direction to unscrew the lamp.
  • the invention also includes, in accordance with a second aspect, a lamp of the type described and comprising a glass envelope having a reflective layer and containing a light rod forming part of an illumination assembly which aligns the rod with a predetermined optical axis of the lamp, said rod being supported at one end by a terminal connection attached to one end of the envelope, and at the other end by a retainer which engages a formation provided at the end of the envelope opposite the terminal connector, the illumination assembly including electrical conductors connecting opposite ends of the light rod to two terminals on the terminal connection respectively, said conductors including a traverse wire located at a position between the light rod and the reflective layer on the envelope and which carries electrical current flowing between one of the terminals and the end of the light rod remote from the terminal connector; in which lamp the formation is of non-circular cross-section and the retainer has a cross-sectional shape which is complementary to that of the retainer and co-operates therewith to hold the traverse wire in a pre-determined angular position about the optical axis
  • the advantage of the second aspect of the invention is that the traverse wire is automatically positioned in its correct angular position by the positive engagement of the retainer with the formation, and such engagement also ensures the adjacent end of the light rod is correctly positioned on the optical axis.
  • the formation may take the form of a spigot or a socket of non-circular cross-section.
  • the formation is constructed as a well of triangular cross- section in the end of the glass envelope opposite to the terminal connection.
  • the catch can be released during fitting of the lamp in the luminaire so that the lamp can be turned until its optimum position is found.
  • the cup-piece can then be engaged with the external surface of the well so that the catch operates to retain the lamp against rotation and end-wise movement throughout its working life.
  • the catch may be provided with a compression spring to assist retention of the lamp firmly in its operating position in the luminaire.

  • Figure 1 shows a gas discharge lamp 1 provided with a non-circular, bulbous glass envelope 2 which provides the lamp with a convex transparent underside 3.
  • the upper part of the envelope 2 provides a convex, multi-vaulted roof 4 which is internally coated with a metallised reflecting film 5 as shown in figure 2.
  • the film 5 has its lower edges 6 lying in a horizontal plane spaced beneath an optical longitudinal axis 7 of the lamp.
  • the roof vaults intersect one another along lines lying in respective planes which are radial with respect to the axis 7.
  • the roof vaults are so shaped that heat and light produced by a light rod 8, positioned on the optical axis 7 of the lamp, is reflected downwards from the film 5 in a direction which misses the light rod 8 so that it is subjected to the minimum of reflected heat from the layer 5.
  • the lamp 1 has a terminal connection provided by an end-portion 9 which is provided with an Edison screw base 100.
  • a base has a central end-terminal 11 and a frusto-conical insulator 13 which insulates the terminal 11 from an external screw terminal 12.
  • the construction of the terminal end-portion 9 is shown in more detail in figures 3, 6 and 7.
  • the screw terminal 12 is formed by an outer metal sleeve 14 which provides external screw threads and which is contiguous with and rotates around a cylindrical inner sleeve 15 so that good electrical contact is maintained between the two sleeves at all angular positions of the outer sleeve 14 with respect to the inner sleeve 15.
  • the glass envelope is provided with a neck 50 at its terminal end which is sealed onto a glass stem 21 , partially shown in figure 1 as well as figure 3, and through which extend parallel electrode wires 23 and 24.

  • the other wire 24 (see Figure 1 ) is connected to the interior wall of the inner sleeve 15 at 59.
  • a cement filling 51 attaches the inner sleeve 15 to the outside wall of the glass neck 50.

  • Figure 7 shows how the sleeves 14, 15 and the collar 18 are assembled together to form a sub-unit.
  • the collar 18 is initially in the form of a cylinder, as shown in the lower part of figure 7, having a radial flange 16 at its lower end.
