摘要： The preferred embodiment of the present invention provides a control system which permits operation of electrically powered apparatus in any one of several active modes from a controller mounted remotely from the apparatus. The system is particularly useful for controlling the operation of at least a pair of light sources. The system permits switching, from the controller, energizing power from an energized light source to a de-energized light source. Electrical communication between the controller of the system and the light head can be provided by only two electrical conductors.

摘要： A controller for controlling operation of a multi-filament lamp is provided that permits selection of the filament to be energized from a control box placed at a remote location from the lamp. Only two leads are required to electrically connect the control box to the lamp. The controller automatically switches energizing power from a burned out filament to an alternate filament. The controller can also include a source of alternate power for the controller in the event that primary power is lost. The controller can also include a lock out feature which prevents switching energizing power at the control box from an energized filament to a failed filament.1. Field of the InventionThe present invention relates to controllers for lamps and, in particular, a controller for a lamp having more than one light source that permits control of the lamp from a location remote from the lamp.2. Description of the Prior ArtLamps having more than one light source are known generally and are useful during the performance of surgical procedures. Such lamps provide a readily available source of light upon failure of one of the light sources of the lamp. For example, the lamp disclosed in U.S. Patent Application Ser. No. 936,240 filed Aug. 24, 1978, discloses a lamp having multiple filaments, each of which provides light having a pattern different from those provided by the remaining sources.Although lamps having more than one light source are more useful during performance of surgical procedures than are lamps with a single light source, several problems are associated with their use. First, the selection of which light source is energized must be made at the lamp head. Further, the switch to an alternate light source upon failure of an energized light source must be accomplished manually which causes a temporary loss of light.SUMMARY OF THE INVENTIONThe present invention provides a controller for a lamp having more than one light source that permits selection of which light source is energized at a location that is remote from the lamp head. Accordingly, personnel performing surgical procedures need not effect light source selection at the lamp head. Further, the present invention senses failure of a light source and automatically switches energizing current to an alternate light source. The apparatus of the present invention which is separated spatially from the lamp head is connected electrically to the lamp head with only two leads. Accordingly, the present invention can be installed easily in existing lamps which receive electrical power through only two leads. New lamps manufactured with the present invention installed are less complicated mechanically and less expensive than lamps which require three or more leads connected between the lamp head and the remotely located control apparatus.The controller of the present invention includes apparatus separated spatially from the lamp for receiving electrical power from a primary source of electrical power and impressing across two leads which communicate electrically with the lamp an electrical potential capable of producing in the leads an electrical current suitable for energizing the light sources. The receiving apparatus includes apparatus for reversing the direction of flow of the energizing current by reversing the polarity of the electric potential. The controller also includes apparatus located at the lamp for permitting energizing current to flow through a light source, which light source is energized depending on the direction of flow of the energizing current. The controller also includes apparatus separated spatially from the lamp for automatically reversing the polarity of the electric potential upon failure of the light source that is energized by the energizing current.The receiving apparatus can include apparatus for preventing the reversing apparatus from effecting a reversal of the polarity of the electric potential that would energize a failed light source. Further, the controller can include an alternate source of electrical power suitable for energizing the light sources and apparatus for supplying power from the alternate source to the controller upon failure of the primary source. Also, the controller can include apparatus separated spatially from the lamp for varying the intensity of the light produced by the light sources.Preferably, the elements of the invention that are separated spatially from the lamp are located in a control box mounted at a convenient location. Reversal of the polarity of the electric potential can be accomplished by a bridgeconfigured switching apparatus comprising four switching devices. The polarity of the impressed voltage depends on which set of two switching devices is conducting. The apparatus for permitting energizing current to flow through one light source is, preferably, a diode.When used herein, the terms "light source" and "filament" shall include elements through which electrical current flows to cause the elements to emit light.
摘要翻译： 提供一种用于控制复丝灯的操作的控制器，其允许从放置在远离灯的远程位置的控制箱中选择要被激励的灯丝。 只需要两根导线将控制盒电连接到灯。 控制器自动将激光功率从烧光丝切换到交替灯丝。 在主电源丢失的情况下，控制器还可以包括控制器的备用电源。 控制器还可以包括锁定功能，其防止控制箱处的通电功率从通电的灯丝切换到故障灯丝。 用于灯的控制器技术领域本发明涉及用于灯的控制器，特别地涉及一种具有多于一个光源的灯的控制器，其允许从远离灯的位置控制灯。 背景技术具有多于一个光源的灯一般是已知的，并且在执行外科手术过程中是有用的。 这种灯在灯的光源之一故障时提供容易获得的光源。 例如，在美国专利申请 1978年8月24日提交的No.936,240公开了一种具有多个细丝的灯，每个灯提供具有与由剩余源提供的图案不同的图案的光。 虽然具有多于一个光源的灯在外科手术过程中比具有单个光源的灯更有用，但是与其使用有关的几个问题。 首先，必须在灯头进行选择哪个光源通电。 此外，在通电光源故障时切换到备用光源必须手动完成，这导致暂时的光损失。
