8 Claims.
(Granted under Title 35, U. s. Code (1952),
sec. 266) p I The present invention relates to a lighting socket and more particularly to a lightin socket for use in transmitting light through the surface of an illuminated plastic sheet.
Plastic surface or edge lighting has become of prime importance in vehicle lighting systems, and particularly for control box and console illumination in aircraft. Lighting of this type is accomplished by transmitting light through the edge of the plastic sheet. and then ejecting the light to the eye of the observer by means of engraved or other suitable markings placed on the surface of the sheet, the remainder of the sheet surface being opaque. Utilization of plastic edge lighting has resulted in a more even illumination of the control surface and a greater visibility particularly in night or blind flying.
In the production of plastic edge lighting systems, difiiculty has been experienced in obt-ain ing a lamp socket which willsatisfactorily illuminate the plastic sheet without utilizing too much of the available space on the panel and without extending too far within the control box or too far beyond the surface of the panel. Furthermore, the socket must be readily accessible so that a defective lamp may be removed, and must be a unitary structure so as to enable quick and ready manufacture and assembly.
Accordingly, an object of the present invention is the provision of a unitary lighting socket for a plastic edge lighting system.
Another object is to provide a lamp socket for a plastic edge lighting system which occupies a minimum of space.
A further object .is to provide .a lamp socket for a plastic edge lighting System which projects :into the control box a minimum distance and projects only a short distance above the illuminated surface.
Still another object is the provision of a watertight socket .for a plastic lighting system.
A still further object of this invention is the provision of .a lamp socket for a plastic edge lighting system in which the lamp may be readily removed, and the electrical connections to the socket may be readily made.
The "exact nature of this invention as well as other objects and advantages thereof will be readily apparent from consideration of the :following specification relating to the annexed drawings .in which:
Fig. .1 is a :front elevational view of an aircraft lighting control box employing plastic edge lighting.
Fig. 2 is .a sectional view along the .line 2-4 of Fig. 1 illustrating one embodiment or the socket of the present invention.
Fig.- 3, is a sectional view similar to Fig. 2 illustrating a second embodiment of the socket of thepresent invention; and p Fig. 4 is a sectional view similar to Fig. 2 illustrating another embodiment of the present invention as applied to a spaced plastic sheet.
Referring now to the drawings, wherein like reference characters designate like or corresponding parts throughout the several views, there is shown in Fig, 1 an aircraft lighting system control box, generally designated H, which comprises a plastic sheet l2 suitably mounted on the front mounting panel l3 of the box, as shown in Fig. 2. Also mounted on panel l3 are various switches M for controllingthe lighting at various points of the aircraft, a master switch l5 for controlling the type of lighting at the.
Various points, a coder 16 for automatically coding the lighting, and a manual coder 11.
Suitably marked on plastic sheet l2, which readily transmits light, are the necessary designations of the various components of control box 1 I. These designations may be marked on sheet :2 in various ways well known in the art, one being to coat the entire surface of sheet I 2 black except for the desired designations, so that the light may penetrate therethrough. The portions of the surface of sheet i2 directly beneath switch l5 and coder l6 are also uncoated so that the light may penetrate therethrough and reach the designations on the dials, which are of similar coated plastic material. It is to be understood that the particular method for marking the designations forms no part of the present invention and that any plastic edge lighting system may be used.
Mounted on panel I 3 are a pair of lamp sockets 38 which support lamps 19 for illuminating sheet I 2 and the markings or designations thereon. One 'form of socket 18 as shown in Fig. 2 comprises an inner shell 2'! having a lead connection '22 at one end thereof, to which is soldered, or otherwise secured, one lead from the power supply, not shown, shell 2| serving as a support ior'lamp 1:9 as clearly shown in Fig. 2. An outer shell 24 is positioned in an opening in mounting plate 13 and sheet I 2 and extends outwardly thereof, shell 24 being provided with a shoulder 25 which rests on the interior surface of plate l3. I-nterposed between shells 2| and 24 is a transparent member 26 which completely Sillrounds lamp [9 and serves as an insulator between theshel-ls. Member 26 is transparent and may be made of glass or plastic for transmitting and shells are held in press fit relationship with each other. If desired, member 26 may be colored so as to act as a filter for transmitting colored light, such as red, to plastic sheet I2.
Referring now to Fig. 3, wherein is shown another embodiment of the present invention, outer shell 34 is provided with conventional bay,- onet slots 33 while cap 39 is provided with retaining pins 36, cap 39 acting directly against flexible washer or gasket 38 to obtain the watertight seal- Outer shell 34 is retained directly upon plate l3 by means of nut 31 which threadedly engages the inner end of shell 34 while shoulder 35 of shell 34 engages the front 01' outer surface of plate l3. In this manner, the socket is directly secured to plate I3 and any damage to sheet l2 due to mounting the socket thereon is removed. The inner shell of the embodiment of Fig. 3 has a central extension 32 thereon which serves as one terminal for the lamp, the remainder of the socket structure being substantially the same as that of Fig. 2.
Fig. 4 discloses a modified arrangement of the socket of Fig. 2 for use with a plastic sheet l2 which is displaced from mounting plate l3 by means of spacers, or other suitable means, 42. Outer shell 44 is supported directly by sheet I2 and is retained in place by nut 41, gasket 48 being provided for making the socket watertight. Outer shell 44 is provided with a projection 45 adapted to be connected to one terminal of the power supply, while inner shell 4| has a central projection 43 thereon for connection to the other terminal of the supply, the electrical circuit being completed through compression spring 46 within cap 49.
It is understood that the bayonet slot arrangement of Fig. 3 may be used with the arrangement of Fig. 4, and that the spacing between plate [3 and sheet |2 need not be greater than that required to permit passage of the terminals from the power supply therethrough.
Obviously, many modifications and variations of the present invention are possible in the light of the above teachings. It is, therefore, to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
