Definitions

  • the invention relates to an illuminating device, and more particularly to a changeable lamp base suitable for use with an energy saving lamp
  • a base of an energy saving lamp is affixed to the lamp.
  • energy saving lamps are restricted in use by different standards and shapes. For example, if a lamp holder is bayonet-type, a screw-type lamp base cannot be used. Moreover, it is required that the inner diameter of the lamp holder fits with that of the lamp base, which brings about inconvenience.
  • Another objective of the invention is to reduce the cost of low volume production of energy saving lamps with different standards and shapes.
  • the invention provides a changeable lamp base, comprising a bottom housing, a bulb holder and a press-type conductor; wherein the bottom housing is removably connected to the bulb holder; a protrusion is disposed at the top of the bottom housing; a groove is disposed at the bottom of the bulb holder, a fixed ring is rotatably connected between the bottom housing and the bulb holder; and the press-type conductor is disposed at the top of the bulb holder.
  • An outer wall of the top of the bottom housing is in the shape of a ladder.
  • An inner diameter portion of the top of the bottom housing is a plug-in portion.
  • An outer diameter portion of the top of the bottom portion is a revolving portion.
  • An outer diameter of the plug-in portion is fit with an inner diameter of the bottom of the bulb holder.
  • a protrusion is disposed outside the plug-in portion.
  • a groove is disposed inside the bottom of the bulb holder. The bottom of the bulb holder is received in the plug-in portion.
  • An outer diameter of the revolving portion at the top of the bottom housing is the same as that of the bottom of the bulb holder.
  • One outer screw thread is disposed on the outer diameter of the revolving portion, and another co-rotating outer screw thread is disposed on the bottom of the bulb holder.
  • An inner screw thread is disposed in the fixed ring, and engaged with the outer screw threads on the revolving portion and the bulb holder.
  • An electric conduction post extends from a center of the top of the bottom housing.
  • the outer wall of the electric conduction post is an insulator.
  • a core of the electric conduction post is a conductive metal pipe, and a conductive metal spring is disposed on one side of the electric conduction post.
  • the press-type conductor is received in the top of the bulb holder via an insulative fastener.
  • the electric conduction post extends from the press-type conductive.
  • a diameter of the electric conduction post fits with an inner diameter of the conductive metal pipe in the bottom housing, and an electric conduction block is disposed in the inner wall of the bulb holder.
  • the press-type conductor is received in the top of the bulb holder via an insulative fastener.
  • the electric conduction post extends from the press-type conductive.
  • a diameter of the electric conduction post fits with an inner diameter of the conductive metal pipe in the bottom housing, and an electric conduction groove is disposed in the inner wall of the bulb holder.
  • the outer housing is of a screw-type or a bayonet-type.
  • the changeable lamp base makes the energy saving lamp more appealing, convenient and economical for use, as a user may easily exchange the different types of bulb holders (such as replacing a screw-type bulb holder with a bayonet-type bulb holder, or a wide-diameter bulb holder with a narrow diameter bulb holder, etc.) as required.
  • the bottom housing of the lamp base of the invention may be separated from the bulb holder, when producing a small volume of lamps having different shapes of bulb holders, a large volume of bottom housings of the lamp bases may be made with the same standard first, then the corresponding circuit boards can be mounted, and finally different bulb holders can be configured, which reduces the production cost, and improves the production efficiency.
  • Fig. 1 is an exploded view of a first embodiment of the invention
  • Fig. 2 is a perspective view of a first embodiment of the invention
  • Fig. 3 is an perspective view of a second embodiment of the invention.
  • Fig. 4 is an exploded view of a second embodiment of the invention.
  • a changeable lamp base is of a screw-type with a large bulb holder, and comprises a bottom housing 5, a bulb holder 4, a press-type conductor 1, an insulative fastener 2 and a fixed ring 3.
  • the bottom housing 5 is removably connected to the bulb holder 4.
  • the fixed ring 3 is rotatably connected between the bottom housing 5 and the bulb holder 4.
  • the press-type conductor 1 is disposed at the top of the bulb holder 4 via the insulative fastener 2.
  • An outer wall of the top of the bottom housing 5 is in the shape of a ladder; an inner diameter portion thereof is a plug-in portion 53. An outer diameter portion thereof is a revolving portion 55. An outer diameter of the plug-in portion 43 is fit with an inner diameter of the bottom of the bulb holder 4. A protrusion 54 is disposed outside the plug-in portion 43. A groove 41 is disposed inside the bottom of the bulb holder. The bottom of the bulb holder 4 is received in the plug-in portion 53. An outer diameter of the revolving portion 55 at the top of the bottom housing is the same as that of the bottom of the bulb holder.
  • One outer screw thread 43 is disposed on the outer diameter of the revolving portion, and another co-rotating outer screw thread 56 is disposed on the bottom of the bulb holder.
  • An inner screw thread 31 is disposed in the fixed ring 3, and engaged with the outer screw threads 43 and 56 on the revolving portion 5 and the bulb holder 4.
  • An electric conduction post 51 is extended from a center of the top of the bottom housing 5.
  • An outer wall of the electric conduction post 51 is an insulator.
  • a core of the electric conduction post 51 is a conductive metal pipe, and a conductive metal spring 52 is disposed on one side of the electric conduction post 51.
  • the press-type conductor 1 is received in the top of the bulb holder 4 via the insulative fastener 2.
  • An electric conduction post 11 is extended from the press-type conductive 1.
  • a diameter of the electric conduction post 11 is fit with an inner diameter of the conductive metal pipe in the bottom housing, and a electric conduction block 42 is disposed in an inner wall of the bulb holder 4.
  • a circuit board and a light pipe are mounted in a lower cavity of the bottom housing 5 (not shown).
  • the press-type conductor 1 is fixed on the bulb holder 4 via the insulative fastener 2 (generally by the manufacturer).
  • the groove 41 inside the bottom of the bulb holder 4 is aligned with the protrusion 54 on the bottom housing 5, and the bottom of the bulb holder 4 is received in the top of the bottom housing 5, so as to insert the electric conduction post 11 on the press-type conductor 1 into the conductive metal pipe in the bottom housing, and to enable the electric conduction block 42 on the inner wall of the bulb holder 4 to abut against the conductive metal spring 52.
  • the fixed ring 3 is rotatably connected to the screw threads 43 and 56 on the revolving portion 5 and the bulb holder 4 assembly of the bulb holder is finished.
  • the bulb holder 4 When the bulb holder 4, the bottom housing, or the lamp pipe need to be changed, firstly the fixed ring 3 is rotatably taken out, and then the bulb holder 4 and the press-type conductor 1 are pulled out, so as to detach the bulb holder 4 from the bottom housing 5, and thus the bulb holder 4 and the bottom housing 5 are changed, which makes the changing convenient without any tools.
  • Embodiment 2 As shown in Figs. 3 and 4, a changeable lamp base is of a screw-type with a large bulb holder. Compared with embodiment 1, since a diameter of a top portion of the bulb holder 4 is small, an electric conduction groove 44 is disposed somewhere in an inner wall of the bulb holder 4, for receiving the conductive metal spring 52 on the bottom housing 5. A structure and a dimension of the bottom portion of the bulb holder 4 of this embodiment are the same as those of the bulb holder 4 of embodiment 1, therefore, both of the bulb holders 4 may be interchanged.
  • the bottom housing is removably connected to the bulb holder, and thus has good generality for large-volume production.
  • the invention is convenient for production, manufacture and use, and has high industrial availability.
