ELECTRICALLY FOCUSED SURGICAL LIGHT |
摘要 |
<p>A multi-filament lamp combination is disclosed which may be used alone and in multi-lamp arrangements with other single land multi-filament lamps to provide pattern size variation from a large diameter flood effect to a smaller diameter spot effect. A spot/flood capability exists to provide large pattern exposure simultaneously with secondary spotlighting. The filaments can be energized selectively from a remote switching station so that the individuals who are scrubbed and gloved need not touch any part of the switching arrangement to change the lamp pattern size. A cluster of lights can contain one or more multi-filament lamps with in the cluster, so that by switching on the rear most filament of the multi-filament lamps and switching off the single filament lamps, a small high intensity pattern is obtained by switching to the other filaments, a large pattern of high intensity is formed. More than two filaments can be provided in each lamp.</p> |
