Abstract
A lighting arrangement in a hospital bed service unit. The service unit is adapted for hanging on the wall in the hospital room and includes a window in the upper portion through which light from a light source is projected. A pair of lamps are mounted in the service unit one of which is arranged to direct light upwardly through the window toward the ceiling to indirectly illuminate the room. The other lamp is arranged to direct the light through the window downwardly toward a bed for examination and reading purposes. Intensity control switches are mounted on the service unit and are connected to the downwardly directed lamp to vary the intensity of the light therefrom so that it may be adjusted from a full high intensity light for examination purposes to a variable desired intensity light for reading and other purposes.

Typically, the service unit includes a pair of pylons and a wall module support bracket having shelves for supporting the pylons. The pylons contain electrical outlets and observation, examination, reading, indirect and night-light lighting facilities. The pylons rest on a support bracket extending upwardly adjacent each side of the bed headboard. One system of this type is disclosed in a commonly assigned copending application Ser. No. 380,356 entitled HOSPI- TAL BED SERVICE UNIT, filed on the same date as this application and incorporated herein by reference.
In some prior art service units, separate light sources are provided for examination, indirect lighting and reading lighting. Such separate facilities, however, add not only to the total cost of the service unit, but also increase its total weight, thereby making its mounting difficult and requiring heavy duty mounting brackets and the like therefor. In addition, the additional components required for the separate lighting, are additional possible areas for failures to occur thereby significantly adding to the overall maintenance costs.
' SUMMARY OF'THE INVENTION The combination lighting assembly of the present invention improves upon the lighting systems of the prior art and is specifically adapted for use in a hospital bed service unit of the type described in the aboveidentified, commonly assigned, copending application. The lighting unit of the present invention fits in such a service unit, the service unit including a window in one wall thereof, having a lens thereover, wherein the improved lighting means includes a pair of lamps fixed in the service unit. One of the pair of lamps is adapted to direct light through the lens generally upwardly toward the ceiling to indirectly illuminate the room. The other of the pair is adapted to direct light through the lens generally downwardly toward the bed which is positioned adjacent the service unit. Intensity control switches are mounted on the service unit and are operatively connected to the downwardly directed light to vary the intensity of the light from a high intensity, for examination purposes, to a variable desired intensity for reading and like purposes.
The many objects and advantages of the present invention will be readily appreciated by those skilled in the art as the invention becomes better understood by reference to the following detailed description and the accompanying drawings illustrating a preferred embodiment of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a fragmentary perspective view illustrating a typical hospital bed and service unit arrangement in which the present invention is utilized;
FIG. 2 is a fragmentary perspective view partially broken away illustrating the lamps mounted in the service unit; a
FIG. 3 is a somewhat schematic cross-sectional view showing the arrangement of the examination and reading lamps; and
FIG. 4 is a somewhat schematic cross-sectional view illustrating the lamp directed upwardly for indirectly lighting the room.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, FIG. 1 is a perspective view of a hospital bed service unit incorporating the lighting system of the present invention. The service unit 10 is of the type described in the above-mentioned commonly assigned copending application entitled HOSPITAL BED SERVICE UNIT. As therein described, the service unit includes a pair of spaced substantially identical pylons 12 supported on the horizontal shelf portion 16 of a wall-mounted support bracket 18. Pylons 12 each carry electrical outlets, suitable switches therefor, speakers, night lights, and the like all as described in the above-identified application. The pylons are adapted for connection by means of an electrical supply line 20 to an external electrical source. The pylons are electrically connected to each other through suitable hidden wiring passing through the mounting bracket 18 so that either one of the pylons may be connected to the supply source.
A high-intensity lamp assembly 38 is positioned adjacent back wall 36 near the top extremity of the pylons. The high-intensity lamp includes a housing 40 mounted in the pylon at an angle with respect to walls 22 and 36. The housing includes a reflector surface 42 for directing the light rays from a light element 44 through lens 28 and downwardly toward the bed.
An intensity control element 5 0 of conventional solid state construction is mounted on one of the pylons at an outer edge thereof and includes'a knob 52 which may be rotated to vary the intensity of the output of high-intensity lamp assembly 38. Suitable electrical wiring 54 is provided to operatively connect lamp 38 to intensity control 50. Intensity control switches 50 comprising switches 51 and 52 is in turn connected via wiring 56 through a switch panel 58 and to supply line 20 to an external power source.
As shown in FIG. 3, lamp assembly 38 is positioned within pylon 12 such that the light rays emitted therefrom are directed through the window opening generally downwardly onto the surface of a bed. Preferably, each pylon includes a similar high-intensity light 38 and wiring means (not shown) are provided between the pylons to interconnect the two lamps. Intensity control switches 51 and 52 are connected to each of the lamps and therefore adjust the intensity thereof. Intensity control switch 52 is a solid state rheostat type control. Switch 51 bypasses switch 52. When intensity control switch 52 is bypassed, highest illumination of the lamps is provided, in which event the lamps are generally used for examination purposes since the light brightly illuminates the bed area. Lower intensity adjustments of lamps 38 are used for reading and like purposes. This is accomplished by simply rotating knob of switch 52 on intensity control 50. It should .be noted that switch panel 58 includes a number of switches and suitable wiring is provided from these switches to the lamps and the intensity control such that one or the other of the lamps may be turned off if desired. The switch 51 is used to bypass the intensity control and obtain examination lighting.
A second lamp assembly 60 is positioned adjacent back wall 38 below the window opening 26 and includes a housing 62. The housing carries conventional base elements to receive a second light element 64 which is preferably a spot or flood-light type of lamp. As shown in FIG. 4, lower lamp-assembly 60 is positioned so as to direct light rays emitted therefrom upwardly through lens 28 toward the ceiling of the room to thereby provide indirect lighting of the room. Lamp assemblies 60 are provided ineach pylon 12 and may be connected by suitable wiring 66 to switches in panels 58 for selective operation thereby.
It may therefore readily be seen by those skilled in the art that the combination lighting assembly in the present invention provides an improved lighting system for use in a hospital bed service unit. Lamps in each pylon service unit are adapted to projectlight therefrom to provide both indirect lighting for the room and additionally light for examination, reading, and other purposes on the bed. The lighting assembly of the invention, because of its minimal number of component parts, reduces the total weight of the service unit and in addition great savings are realized in the cost of manufacturing and in the costs of operation of the service unit. Other modifications and variations will be suggested to those skilled in the art without departing from the scope of the invention as defined by the following claims.
