Description
Attorney Docket No.: 04-1-767 HIGH TEMPERATURE LAMP CONNECTOR AND SOCKET FOR
DOUBLE-ENDED LAMP
TECHNICAL FIELD
This invention relates to lamp sockets and more particularly to high-temperature lamp sockets for double-ended lamps BACKGROUND ART
Double-ended metal halide arc discharge (amps are known. Some kinds of these lamps have achieved wide usage in entertainment lighting. One particular version of such a lamp is designated SharXS~ and is produced by Osram Photo-Optic. Lamps of this type are available from Osram Sylvania Inc., Danvers, MA 01923. These lamps are provided in wattages from 200 to 1200 and operate at quite high temperatures. In fact, typical operating temperatures in area of the connector are in the range of 200 to 300°C in lamp fixtures. It is, of course, imperative that the connectors employed with these lamps also be able to operate for long periods of time at such temperatures and still maintain good electrical contact. One type of socket for double-ended lamps is shown and described in German Gebrauchmuster No. 295 04 517, filed March 22, 199. The socket comprises a pair of spaced ceramic bodies containing electrical contacts in the form of a clip with a single lateral retaining spring. However, because of the limited number of contact surfaces and the single retaining spring, poor electrical and mechanical contact with the lamp can result, particularly after multiple lamp insertions and high-temperature operation. In particular, bending or over depression of the single retaining spring will result in poor or no electrical contact or a lack of contact force.
SUMMARY OF THE INVENTION
It is, therefore, an object of the invention to obviate the disadvantages of the prior art.
Attorney Docket No.: 04-1-767 It is another object of the invention to provide connectors that enhance high-temperature lamp sockets, It is yet another object of the invention reduce the cost of high-temperature lamp sockets.
Still another object of the invention is the reduction of the complexity of such sockets.
These objects are accomplished, in one aspect of the invention. by a connector for a lamp that comprises a ceramic housing having a top surface and a bottom surface and including a contact receiving area formed in the top surface. An electrical contact is positioned in the contact receiving area, the electrical contact having a rectangular base with two sides and two ends and having opposed, upright walls extending from the sides of the base. An upright clip extends from an end of the base and the upright walls and the upright clip have portions projecting beyond the top surface of the ceramic housing to receive an end of a lamp therein. The electrical contact is mounted within a supplemental spring having opposed legs which are adjacent to the upright walls of the contact. The supplemental spring engages the upright walls when a lamp is inserted in order to maintain contact force during operation of the lamp.
In another aspect of the invention, a lamp socket is provided for a double-ended lamp wherein the lamp socket has opposed connectors as described above. The opposed connectors are separated by a given distance and attached to a connecting bar.
The contact design improves the insertion and retention forces resulting in better insertion and retention of the lamp, lower contact resistance, and lower contact temperature. The lower insertion force results in less stress on the lamp during installation.
The improved retention force during lamp operation results in a longer operating life and better long-term performance after multiple lamp installations.

DETAILED DESCRIPTION OF THE INVENTION
For a better understanding of the present invention, together with other and further objects, advantages and capabilities thercoi~, reference is made to the following disclosure and appended claims taken in conjunction with the above-described drawings.
Referring now to the drawings with greater particularity, a socket 5 for a lamp 12 comprises a pair of opposed connectors 10. The connectors 10 include single-piece ceramic housings 14 each having a top surface 16 and a bottom surface 18 and including a contact receiving area 20 formed in the top surface 16. In a preferred embodiment of the invention the ceramic is a steatite. Other useful ceramics include cordiorite, alumina, and porcelain. The one-piece ceramic housin~~ design reduces the number of parts as well Attorney Docket No.: 04-1-767 as the overall weight. An electrical contact 22 is positioned in the contact receiving area 20 and secured by any suitable means, such as eyelet 80. ~~he electrical contact 22 has a rectangular base 24 with two sides 26, 28 and two cads 30. 32 and is preferably made from a high temperature nickel, such as 201 Nickel. It may also be desirable to provide the electrical contact with a pure nickel plating at a thickness of 2-4 microinches.
Opposed, upright walls 34, 36 extend from the sides 26, 28 of the base 24, and an upright clip 38 extends from one end of the base, for example, end 30. The upright walls 34, 36 and the upright clip 38 have portions projecting beyond the top surface 16 of the ceramic housing 14 to receive an end 40 of the lamp 12 therein.
Because the end 40 of the lamp 12 is generally cylindrical, the opposed, upright walls 34, 36 have curved terminal ends 42 to accommodate the curved surface and additionally the opposed, upright walls 34, 36 are resilient so as to fi-ictionally engage the end 40 of the lamp 12.
The upright clip 38 has its terminal end 44 horseshoe-shaped to engage a second zone 46, typically a threaded projection, of the end 40 of the lamp 12.
To further insure good electrical and mechanical contact between the lamp and upright walls 34 and 36, the electrical contact 22 is mounted within a supplemental spring 50.
The supplemental spring 50 is substantially U-shaped with a bight 52 positioned beneath the rectangular base 24 of the electrical contact 22 and with its opposed legs 54, 56 adjacent to the upright walls 34, 36. The opposed legs 54, 56 of the supplemental spring 50 engage the upright walls 34, 36 of the contact 22, particularly when a lamp is inserted, providing increased tension thereto. Preferably, the supplemental spring material should substantially retain its resiliency to at least a temperature of about 300-350°C. More preferably, the supplemental spring 50 is made from Inconel 718. The contact structure with the supplemental spring greatly enhances the retention ol~ the lamp.
Furthermore, Attorney Docket No.: 04-1-767 the additional contact surfaces act to reduce the electrical resistance between the lamp and the connectors.
An alternative embodiment of the supplemental spring SOa is shown in Fig. 6.
The opposed legs 54a, 56a have a notch 90 located in a region adjacent to bight 52. By adjusting the size of the notches 90 in the supplemental spring SOa, it is possible to change the force applied to the upright walls 34, 36 of the contact 22 without changing the spring material itself. In a preferred embodiment, the supplemental spring is made from 0.040-inch thick Inconel 718, each notch is 0.06 inches high by 0.09 inches deep, and the opposed legs are about 0.188 inches wide.
A wire connector 60 is attached to the upright clip 38 by a screw or bolt 65 and comprises a metal block 62, preferably of brass, and can be nickel plated. The block 62 has two orthogonal apertures 64, 66 therethrough; a first of the apertures, for example 64, for receiving the screw or bolt 65 to mount the wire connector 60 to the upright clip 38. The second of the apertures 66 is formed to receive a wire from a power supply.
Preferably, the aperture 66 comprises a bore through the metal block 62 so that the wire from the power supply may be inserted from either side of the block.
As noted, the socket 5 comprises opposed connectors 10 that are separated by a given distance and are attached to a connecting bar 70, as by eyelets 23.
Figs. 4 and 5 are graphs comparing the contact resistance and contact temperature of the lamp socket of this invention versus a prior art socket similar to the one described in German Gebrauchmuster No. 295 04 517. The data was obtained by operating identical lamps in the lamp sockets which were not installed in fixtures. The data is shown as a function of operating time. The advantages of lower contact resistance and lower contact temperature for the lamp socket of this invention are evident.
Attorney Docket No.: 04-1-767 While there have been shown and described what are present considered to be the preferred embodiments of the invention, it will be apparent to those skilled in the art that various changes and modifications can be made herein without departing from the scope of the invention as defined by the appended claims.

DETAILED DESCRIPTION OF THE INVENTION
For a better understanding of the present invention, together with other and further objects, advantages and capabilities thercoi~, reference is made to the following disclosure and appended claims taken in conjunction with the above-described drawings.
Referring now to the drawings with greater particularity, a socket 5 for a lamp 12 comprises a pair of opposed connectors 10. The connectors 10 include single-piece ceramic housings 14 each having a top surface 16 and a bottom surface 18 and including a contact receiving area 20 formed in the top surface 16. In a preferred embodiment of the invention the ceramic is a steatite. Other useful ceramics include cordiorite, alumina, and porcelain. The one-piece ceramic housin~~ design reduces the number of parts as well Attorney Docket No.: 04-1-767 as the overall weight. An electrical contact 22 is positioned in the contact receiving area 20 and secured by any suitable means, such as eyelet 80. ~~he electrical contact 22 has a rectangular base 24 with two sides 26, 28 and two cads 30. 32 and is preferably made from a high temperature nickel, such as 201 Nickel. It may also be desirable to provide the electrical contact with a pure nickel plating at a thickness of 2-4 microinches.
Opposed, upright walls 34, 36 extend from the sides 26, 28 of the base 24, and an upright clip 38 extends from one end of the base, for example, end 30. The upright walls 34, 36 and the upright clip 38 have portions projecting beyond the top surface 16 of the ceramic housing 14 to receive an end 40 of the lamp 12 therein.
Because the end 40 of the lamp 12 is generally cylindrical, the opposed, upright walls 34, 36 have curved terminal ends 42 to accommodate the curved surface and additionally the opposed, upright walls 34, 36 are resilient so as to fi-ictionally engage the end 40 of the lamp 12.
The upright clip 38 has its terminal end 44 horseshoe-shaped to engage a second zone 46, typically a threaded projection, of the end 40 of the lamp 12.
To further insure good electrical and mechanical contact between the lamp and upright walls 34 and 36, the electrical contact 22 is mounted within a supplemental spring 50.
The supplemental spring 50 is substantially U-shaped with a bight 52 positioned beneath the rectangular base 24 of the electrical contact 22 and with its opposed legs 54, 56 adjacent to the upright walls 34, 36. The opposed legs 54, 56 of the supplemental spring 50 engage the upright walls 34, 36 of the contact 22, particularly when a lamp is inserted, providing increased tension thereto. Preferably, the supplemental spring material should substantially retain its resiliency to at least a temperature of about 300-350°C. More preferably, the supplemental spring 50 is made from Inconel 718. The contact structure with the supplemental spring greatly enhances the retention ol~ the lamp.
Furthermore, Attorney Docket No.: 04-1-767 the additional contact surfaces act to reduce the electrical resistance between the lamp and the connectors.
An alternative embodiment of the supplemental spring SOa is shown in Fig. 6.
The opposed legs 54a, 56a have a notch 90 located in a region adjacent to bight 52. By adjusting the size of the notches 90 in the supplemental spring SOa, it is possible to change the force applied to the upright walls 34, 36 of the contact 22 without changing the spring material itself. In a preferred embodiment, the supplemental spring is made from 0.040-inch thick Inconel 718, each notch is 0.06 inches high by 0.09 inches deep, and the opposed legs are about 0.188 inches wide.
A wire connector 60 is attached to the upright clip 38 by a screw or bolt 65 and comprises a metal block 62, preferably of brass, and can be nickel plated. The block 62 has two orthogonal apertures 64, 66 therethrough; a first of the apertures, for example 64, for receiving the screw or bolt 65 to mount the wire connector 60 to the upright clip 38. The second of the apertures 66 is formed to receive a wire from a power supply.
Preferably, the aperture 66 comprises a bore through the metal block 62 so that the wire from the power supply may be inserted from either side of the block.
As noted, the socket 5 comprises opposed connectors 10 that are separated by a given distance and are attached to a connecting bar 70, as by eyelets 23.
Figs. 4 and 5 are graphs comparing the contact resistance and contact temperature of the lamp socket of this invention versus a prior art socket similar to the one described in German Gebrauchmuster No. 295 04 517. The data was obtained by operating identical lamps in the lamp sockets which were not installed in fixtures. The data is shown as a function of operating time. The advantages of lower contact resistance and lower contact temperature for the lamp socket of this invention are evident.
Attorney Docket No.: 04-1-767 While there have been shown and described what are present considered to be the preferred embodiments of the invention, it will be apparent to those skilled in the art that various changes and modifications can be made herein without departing from the scope of the invention as defined by the appended claims.
