At least two launches LED and the LED of at least two transmitting cool white light, the material selection of described light penetrating panel 3 of warm white
Lucite or simple glass, the upper surface of described light penetrating panel 3 is inclined-plane or double inclined plane, and lower surface is plane or monocline
Face, described inclined-plane includes circular sloped surface, square sloped surface or hexagon inclined-plane, and described shade controls parts 5 and includes a signal
Receptor (not marking in figure) and a signal projector (not marking in figure).
Change the size of hot spot by the method for electrical adjustment, need illumination spot to be divided into multistage illumination region, by electricity
Stream changes the brightness proportioning in illumination regions at different levels and makes the ascending change of whole hot spot.Hot spot change during colour temperature,
Center brightness and illumination depth all can keep constant.In the implementation case, we use LED as illuminating source, will illuminate
Region is divided into 2 grades: being respectively spot center and hot spot is peripheral, as it is shown in figure 1, now, the LED on operating lamp lamp plate divides 4 kinds,
Figure is respectively labeled as a1, a2, b1 and b2.The illumination region of wherein a1, a2 is the center of hot spot, and that a1 launches is 3500K
Warm white, what a2 launched is the cool white light of 5000K；The illumination region of b1, b2 is the periphery of spot center, and b1 launches
Being the warm white of 3500K, what b2 launched is the cool white light of 5000K.By regulation a1, a2 and b1, the luminous power of b2 can make
The colour temperature of hot spot is adjustable in the range of 3500K-5000K.Such as, working as that a1, b1 be bright and a2, when b2 does not works, hot spot colour temperature is 3500K；
Working as brightness and the a2 of a1, b1, when b2 brightness is identical, hot spot colour temperature is 4250K；Work as a1, b1 not work and a2, hot spot colour temperature when b2 is bright
For 5000K, by suitably regulating a1, a2 and b1, b2 luminous strong and weak is so that under conditions of center spot intensity is constant
The size of hot spot changes.Such as, working as a1, a2 all light and b1, when b2 does not works, hot spot is minimum, such as labelling 1.0 institute in Fig. 1
Refer to；Work as that a1, a2 brightness is relatively strong and time b1, b2 brightness is more weak, hot spot be centre size, such as labelling 2.0 indication in Fig. 1；Work as a1, a2
More weak and b1, when b2 is stronger, hot spot is maximum, such as labelling 3.0 indication in figure.The mode of this electrical adjustment has only to by changing
The electric current power proportioning becoming operating lamp each ingredient LED can realize the independence of colour temperature, spot size and brightness and appoint
Meaning regulation, method is simple, simple operation, ensures center brightness and illumination depth not during colour temperature and spot size change
Becoming, the whole structure of hot spot is good.
More than use LED as light source, actually can also use other kinds of light source.
Warm white and two kinds of LED of cool white have more than been used to carry out colour temperature regulation, actually can also be with 3 kinds and above LED
Lamp carries out colour temperature regulation.
Above for simplifying explanation, spot area is divided into 2 grades, respectively Shi Zhao center (a1, a2) and according to peripheral (b1,
B2), the regulation of spot size is carried out by regulating brightness proportioning at different levels.Actually can also with 3 grades (respectively according to center,
According to middle part with according to edge) or the LED of more stages carry out spot size regulation.The most replacement scheme of classification has bigger hot spot
Range of accommodation, but the LED number used also can be the most.
As in figure 2 it is shown, the present invention uses multi-blade type structure design operating lamp promote without shadow rate and promote that cross-ventilation dissipates
Heat.Containing irradiating LED a of spot center and irradiating peripheral LED b on spider 1 and fan disk 2, and their number
Amount carries out suitable proportioning as requested.The blade of each fan incidence from different perspectives all can be right to use multi-blade type design ensure that
The various piece of hot spot produces contribution, even if partial blade is blocked, still has light to arrive operative region, not only has higher
Rate without shadow, and the size of the hot spot after being blocked and colour temperature still keep constant.
Above for simplifying explanation, use fan spider 1 and a multi-blade type structure for two fan leaf dishes 2, it practice, leafy
The structure of formula design freely can set according to the needs of moulding, and the LED on every fan leaf dish 3 all includes at least irradiation 2 grades
The component of hot spot.
In order to realize the electrical adjustment of spot size, the illumination region of each LED is intended to through particular design, must
Their crevice projection angle accurately need be controlled.In order to achieve the above object, we have employed in the front of LED special
Light is controlled by the multi-angle refraction light penetrating panel 3 of design, as it is shown on figure 3, multi-angle refraction light penetrating panel 3 is by some
Refraction structure forms, and the refraction structure in each LED front is different.During design first by LED according to illumination region
Classify, such as, according to LED a and LED b of irradiation speckle periphery of spot center.Further according to each LED and projection area thereof
The position in territory is calculated the inclination angle of corresponding plane of refraction according to formula.The light that LED sends is after the refraction of plane of refraction
Just can accurately project respective illumination region such that it is able to realize the regulation of spot size.Relative to directly changing LED
The method towards the crevice projection angle controlling light of base, uses the method for multi-angle refraction light penetrating panel 3 can allow LED
Arranging tightr at grade, structure is smaller and more exquisite, simple, overall more attractive.
Below the upper surface of light penetrating panel 3 uses inclined-plane, lower surface to use the mentality of designing of plane in figure 3, it practice,
Can also use double inclined plane, lower surface is the designs such as monocline face, and the moulding on each inclined-plane can be circular, square, hexagonal
Shape etc..Any refraction structure utilizing light penetrating panel 3 carries out reflecting the similar approach of luminous intensity distribution all should be in protection scope of the present invention
Within.
As shown in Figure 4, use shade to control technology and can promote the rate without shadow of operating lamp further.Have on each blade
One shade controls parts 5, and in the present embodiment, it comprises a signal projector (not marking in figure) and a signal receives
Device (does not marks in figure).Signal projector launches laser at an angle under operating lamp, if laser after running into shelter 4 is
Scattering, some scattered light can return and received by signal receiver.Control shade by software and control the dutycycle of parts
So that control component working to avoid interfering with each other at same time only one of which shade.Signal receiver receives scattering
After optical signal, the lamp brightness of this fan leaf dish 2 can suitably weaken, and the lamp brightness of other blades suitably strengthens so that after being blocked
Hot spot brightness remain unchanged as far as possible, thus promote the effect without shadow of operating lamp.
In actual operation process, due to reasons such as the head of doctor may frequently move, cause laser by frequently
Block.If operating lamp receives these interference signals and still makes the reaction of frequent changes brightness, visual effect can be affected.
We use delay error correcting technique maximized can avoid the problems referred to above.The principle of this technology is: in shade controls parts 5
One timer is set and a length of delay, such as delay time are 10 seconds.When the occlusion state of operating lamp changes every time
Becoming, the timer in software all can be cleared reclocking, and only when timers value reaches 10, operating lamp just does depanning
Formula changes response.Illustrated below: to assume that original state state laser is not blocked, be now state 1.If meeting the screening of barrier afterwards
Gear, then enter state 2, and timer resets timing, and now operating lamp wouldn't do and react, if occlusion state changes again in 10 seconds
Become (such as barrier removes, then be returned to state 1, or another beam of laser is blocked, then enter state 3), now timer
Again resetting reclocking, operating lamp does not the most do and reacts, if state 2 remains in that after 10 seconds, then it is assumed that this state is stable
, enumerator stop timing going forward side by side row mode switching, thus can avoid the impact that external interference is brought.
The present invention proposes multiple light courcess array that a kind of operating lamp comprises operating lamp lamp plate, is placed on lamp plate, is placed in light source
The multi-angle of array dead ahead reflects light penetrating panel and the shade control parts etc. being placed on lamp plate.Foregoing operating lamp
Lamp plate plays the effect of fixed light source；Foregoing multiple light courcess array (i.e. light source) can use the LED chip of different-colour
And light-distribution lens rearranges (general designation LED)；Foregoing multi-angle refraction light penetrating panel is by light transmissive material (such as glass
Glass or lucite etc.) constitute, the light source of corresponding diverse location, the refraction angle of light penetrating panel is the most different.The light of light source outgoing
On multi-angle refraction light penetrating panel, the deflection at refraction angle, projects different illumination regions.Foregoing shade controls
Parts, are made up of a signal projector and a signal receiver, such as, laser can be used as the letter launched and receive
Number, when the laser that these parts are launched is blocked and returns to the receptor of correspondence, it is bright that operating lamp can make regulation lamp panel automatically
The feedback of degree, promotes the rate without shadow of operating lamp.In order to prevent laser from frequently being switched by frequently blocking the state caused, software uses
Postpone error correcting technique and avoid the adverse effect of interference signal.
Multi-blade type operating lamp proposed by the invention, uses the electrical adjustment mode of a key touch-control to control the bright of each light source
Degree power, the colour temperature to operating lamp, brightness and spot size that can be independent be adjusted.During regulation, arbitrarily join
Other parameters all will not be impacted by the change of number, and the uniformity of hot spot and illumination depth remain constant.Owing to it is adopted
By electrical adjustment rather than the mode of mechanical adjustment, designing simple and reliable, the lighting quality of hot spot is good, operates the easiest.
The method for designing of multi-angle refraction light penetrating panel is not only simple in structure, and moulding is frivolous attractive in appearance, also greatly increases the freedom of design
Degree, improves without shadow rate.Shade controls technology can enter one according to the brightness of the occlusion state Automatic adjusument lamp panel of operating lamp
Step improves the effect without shadow of operating lamp.Postpone error correcting technique and then shield the adverse effect that interference signal brings.
