Description
Technical field
The present invention relates to a kind of lighting device and means of illumination, particularly relate to a kind of surgical operation microscope lighting device and means of illumination thereof.
Background technology
Existing surgical operation microscope means of illumination mainly comprises following several:
1. high-power Halogen lamp LED or gas-discharge lamp illumination: the method comprises the parts such as light-source box, Medical light-guiding fiber, optically focused-projector (being usually integrated in the camera lens of surgical operation microscope).Wherein light-source box is core component, its primarily of light source (high-power Halogen lamp LED or gas-discharge lamp), ensure the power supply that normally works of light source and a few part composition such as cooling system, filter element, light source-fiber coupling system.During instrument work, the light that light source sends first after filtration optical element filters out harmful ultraviolet and infrared composition, then Medical light-guiding fiber is imported by light source-fiber coupling system and in its other end outgoing, emergent light illuminates the surface (being usually referred to as object plane) needing to observe after optically focused-projector.The method is the most frequently used means of illumination of current surgical operation microscope lighting technical field, and its advantage is that structure is very ripe, R&D risk is lower, but its shortcoming is also very obvious, comprising:
A. structure is comparatively complicated: Halogen lamp LED and gas-discharge lamp due to the life-span shorter, need an extra increase light source for subsequent use when therefore designing light-source box, and design corresponding switching mechanism for it, like this when breaking down in certain light source surgical procedure, user switches to standby power source rapidly by switching mechanism, to ensure carrying out smoothly of operation.In addition, because the emission spectrum of Halogen lamp LED and gas-discharge lamp contains more harmful ultraviolet and infrared composition, the special filter element of design during practical application, is needed to filter.
B. use cost is higher: be equally due to Halogen lamp LED and the gas-discharge lamp life-span shorter, in the useful life of instrument, user needs often to change light source.In addition, the Medical light-guiding fiber in the method along with service time prolongation can aging gradually and and then affect its optical transmission efficiency, therefore also need user to regularly replace.
C. the efficiency of light energy utilization is low: why the method uses Medical light-guiding fiber as biography optical element, its main cause is the ultraviolet component that optical fibers can filter in light source emission spectrum further, and the larger light-source box of operating noise (needing powerful fan to dispel the heat during work) can be made as far as possible away from user.But, the maximum drawback of Medical light-guiding fiber is that its light transmittance is low, generally all below 40%, if consider the luminous energy loss of other components and parts again, the actual efficiency of light energy utilization is lower, and this is also the main reason that the lighting source of the method all adopts high-power (generally all at more than 100W) Halogen lamp LED and gas-discharge lamp.
2. small-power Halogen lamp LED integrated lighting: compared with method one, the method eliminates the parts such as light-source box, Medical light-guiding fiber, be integrated in the camera lens of surgical operation microscope by small-power Halogen lamp LED (only needing the small-power radiator fan of low noise to carry out dispelling the heat or do not need heat radiation) and optically focused-projector, this just overcomes the baroque shortcoming that method one exists.But, because small-power Halogen lamp LED exists the disadvantage that the life-span is short, luminous efficiency is low equally, although cancel Medical light-guiding fiber can to a certain extent lowering apparatus use cost, improve the efficiency of light energy utilization, but be difficult to fundamentally improve.In addition, in small-power Halogen lamp LED emission spectrum, there is infrared and ultraviolet component equally, therefore, need to design corresponding filter element or method is filtered, objectively add application cost.
3. multichannel power-type LED integrated form light-combined illuminating: the method is the further improvement to method two, it adopts power-type LED (Light Emitting Diode, light emitting diode) as lighting source, it is long (generally more than tens thousand of hours that the method can make full use of the life-span that LED has, without the need to changing light source in instrument useful life), luminous efficiency is high, the advantages such as security high (without any ultraviolet and infrared composition in emission spectrum), fundamentally improve the lighting quality of surgical operation microscope, simplify lighting system structure, the use and maintenance cost of lowering apparatus.But LED is as a kind of lambert's dignity illuminating source, and its " optically focused " effect is poor, and existing optically focused-projector element has been difficult to improve.For this reason, simultaneously current way uses multichannel (being generally two-way) power-type LED as lighting source, by being projected to object plane again after optics (being generally prism, lens or its combination) optically focused, conjunction light.Obviously, the existence of LED multi-path can improve complexity and the cost of system, and reduces the reliability of system, and in addition, multichannel power-type LED also has higher requirement to heat radiation, and Wind Volume fan namely must be used to dispel the heat, and this can improve the operating noise of system undoubtedly.
