The device comprises a support frame, a plurality of light-emitting diode (LED) light sources and a plurality of lenses, wherein the plurality of LED light sources are arranged on the support frame; and the plurality of lenses correspond to the LED light sources one to one, are arranged in front of each corresponding LED light source, and gather light rays emitted by the plurality of LED light sources to a target position. By the medical illumination device, the utilization rate of light emitted by the light sources is improved, and a multi-layer illuminated surface and an ideal operation illumination space are provided; the light path structure of the medical illumination device is simplified, and the volume of the medical illumination device is reduced while the requirement on the function of weakening the shadow of an object illuminated by the light, which is needed to be realized, is met, so that clean air can more easily arrive at the position of an operation wound, and the hidden danger of hurting personnel (such as a doctor who performs an operation activity, and the like) who participate in a medical treatment activity is eliminated.
Description
Technical field
The present invention relates to the medical illumination field, especially relate to a kind of medical illumination device.
Background technology
In curative activity (operation), lighting requirement to lighting for medical use equipment is different with the lighting requirement of general lighting equipment, lighting for medical use equipment not only will provide illumination to the zone of the curative activity (operation) that carried out, and will have and weaken light and be subjected to function, and to provide the 3D region of an illumination, colour rendering index, colour temperature unanimity according to the shade of thing what irradiation was subjected to be produced when the thing.
The existing lighting for medical use equipment that is used for curative activity (operation), in this equipment in order from different perspectives light to be projected shadow surface, thereby reach the effect that weakens shade, adopting all is on a spherical arc surface luminous point to be set, send out the some direction of illumination perpendicular to arc surface tangent the plane, each luminous point on the circular arc exposes to area of illumination from different directions, thereby reaches the light channel structure method that can weaken hatching effect.123
As shown in Figure 1, provided a kind of existing lighting for medical use equipment among Fig. 1, this lighting for medical use equipment is by circular arc type reflection shield 1 ', based on halogen bulb 2 ', filter 3 ' is formed, in entire equipment, has only a single light source, a reflection shield, its light channel structure method is that circular arc type reflection shield 1 ' is made up of the facet of different angles, the light that based on halogen bulb sends is projected to the facet on the circular arc type reflection shield 1 ', facet reflects light, just form numerous luminous points on the reflection shield 1 ' arc surface like this, each luminous point reflexes to light from numerous different angles and is subjected to according to object, thereby forms the effect that weakens shade.Simultaneously, in this lighting for medical use equipment, also be provided with an adjusting device 5 ', regulate the position relation of based on halogen bulb 2 ' relative circular arc type reflection shield 1 ', to change the area of illumination 4 ' that this lighting for medical use equipment is thrown light on.
Adopt the lighting for medical use equipment of structure as shown in fig. 1, the utilization rate of light that light source sends is extremely low.The principle of luminosity of based on halogen bulb 2 ' is the emission of 360 ° of ball-types, and reflection shield 1 ' can only be wherein 30% reflects, and passes through filter 3 ' and again the light that reflects is filtered 60%.Because area of illumination 4 ' is the stack of each light source, the illumination degree of depth is very poor.In addition, based on halogen bulb 2 ' also send the infrared ray that object temperature is raise, and filter 3 ' can only filter out the part infrared ray when sending visible light, the part infrared ray still arrives area of illumination 4 ' by reflection shield 1 ', causes area of illumination 4 ' temperature to raise.When carrying out curative activity (operation), the temperature of wound site need be lowered, with the survival of prolongation wound tissue, yet the unavoidable meeting of existing lighting for medical use equipment causes area of illumination 4 ' temperature to raise, make the wound temperature raise, this can produce injury to the patient.
Simultaneously, adopt the lighting for medical use equipment of structure as shown in fig. 1, owing to have only a reflection shield 1 ', a light source 2 ', all illumination light, be that light source 2 ' reflects from a reflection shield 1 ', the area of illumination 4 ' of reflection shield has only one, and the area of space of a desirable illumination, colour rendering index, colour temperature unanimity so just can not be provided.
In addition, the lighting for medical use equipment reflection shield of structure shown in Fig. 1 is very big, cause this lighting for medical use equipment volume very big, when being used for curative activity (illumination) illumination, can hinder clean air and arrive the surgical wound position, easily the personnel (doctor of the activity of performing a surgical operation etc.) that participate in curative activity be damaged.
