Description
Technical field
This invention relates to a kind of LED operation shadowless lamp, belongs to the operation shadowless lamp technical field.
Background technology
Operation shadowless lamp is used for the operative site that throws light on.Traditional shadowless lamp adopts incandescent lamp or halogen tungsten lamp as light source, but the optical efficiency of incandescent lamp or halogen tungsten lamp is low, colour rendering is poor, and the focal beam spot diameter is little, and light Jiao is shallow, and service life is short.Because above-mentioned shortcoming, patient's eyes are tired easily, are unfavorable for the quality of performing the operation.Simultaneously during corrective surgery, the heat that shadowless lamp produced, big to the damage of inside of human body cell tissue, be unfavorable for patient's rehabilitation.And the LED light fixture have spectrum narrow, photochromic pure, than common incandescent source have higher luminous efficiency, power consumption is little and long service life characteristics and being used widely.Advanced at present operation shadowless lamp adopts light emitting diode as light source, the multi-group light-emitting diode unit is installed on the lampshade, by increasing the no shadow degree requirement that quantity of light source reaches operation shadowless lamp.But the shadowless lamp of said structure still exists little and shallow, unclear to the different depth structure observation problem of light Jiao of focal beam spot diameter.Simultaneously because the basis of light emitting diode can produce heat when work, and the heat that is arranged on the Light-Emitting Diode on the lampshade only relies on the cross-ventilation heat radiation, so heat dispersion is not good, after light emitting diode divides heating, influence the efficient of light emitting diode, and reduce service life.
Summary of the invention
The purpose of this invention is to provide a kind of compact conformation, can increase the focal beam spot diameter and the illumination degree of depth, and the LED operation shadowless lamp of good heat dissipation effect.
The present invention is that the technical scheme that achieves the above object is: a kind of LED operation shadowless lamp, comprise shell, be hemispheric reflection shield, diffuser and LED lamp, it is characterized in that: described shell inboard has and is the heat conduction bar that distributes shape, the axle sleeve on lamp socket top is installed in the fairlead of cover top portion, lamp socket diameter of axle periphery is equipped with annular LED lamp group, the middle heat pipe that is installed in the lamp socket endoporus is connected with fairlead, plural outer heat pipe is installed on the lamp socket, fan base is installed in the lamp socket bottom, fan is installed on the fan base, reflection shield is positioned at the top of annular LED lamp group, shell is connected with diffuser with reflection shield, be provided with heat-dissipating space between reflection shield and the shell, Connection Block is bearing on the diffuser, and the adjusting rod that is connected with fan base passes Connection Block and is connected with regulating handle.
The present invention adopts annular LED lamp group, make of the outer circumferential periphery diffusion of the light-emitting area of LED lamp around the lamp socket diameter of axle, the optics fan who forms by a plurality of LED light-emitting areas looses, and synthetic large-area light source shines light on the working region of operation from multi-angle after the reflection shield overall reflective, increased the focal beam spot diameter, colour rendering index is big, and colour temperature is true to nature, and gloss is evenly distributed, so guarantee that surgical field of view has enough brightness, patient's eyes indefatigability.
The present invention is equipped with heat pipe on lamp socket, fast the heat that annular LED lamp group is produced is reached lamp socket and connected shell equably by heat pipe, and the heat-delivery surface by lamp socket and shell is with heat and surrounding air convection current, compact conformation is reasonable, owing to increased substantially heat transfer rate and area of dissipation, thereby effectively control the junction temperature of high-powered LED lamp, make that the LED lamp can be normally stably luminous, also the temperature because of the working region is lower, has reduced inside of human body cell tissue is caused damage.
Two groups of above annular LED lamp groups that the present invention is provided with vertically, the light-emitting area of each the LED lamp setting that interlaces on the two adjacent groups annular LED lamp group, light source is more even to the periphery diffusion, and increased the illumination degree of depth of shadowless lamp, make the patient can observe the interior tissue of human body different depth better, guaranteed the operation quality.The present invention adopts two groups of above annular LED lamp groups, can play the effect of major-minor light source, need not major-minor lamp handover operation, and compact conformation reduces the volume of shadowless lamp.
