Abstract
The invention relates to medical illumination equipment, in particular to a shadowless lamp for use in an operation, more particular to an LED (light emitting diode) shadowless lamp. The LED shadowless lamp comprises a round lamp shell, wherein a plurality of LED lamp plates are arranged in the lamp shell; control circuits for LED lamps are arranged on the lamp plates; the LED lamps on the lamp plates comprise LED lamps with color temperature of 4000K and LED lamps with color temperature of 6500K; each lamp plate is provided with four rows of LED lamps, and one LED lamp, two LED lamps, three LED lamps and four LED lamps are uniformly arranged in sequence from the center of a sector to the outside; and the rows of LED lamps on the six lamp plates form four concentric circles in the lamp shell. According to the LED shadowless lamp provided by the invention, an LED lamp set is adopted; the power is low; the color temperature, the illuminance, the color development index and the like all meet the standards of the industry; and the lamp set has long service life and low manufacture cost, and has a certain value for promotion and application.
Description
Technical field
The present invention relates to medical illumination equipment, especially use shadowless lamp required in operation, specifically a kind of LED shadowless lamp.
Background technology
Shadowless lamp mostly is halogen tungsten lamp as light source at present, adopts multiple tiny mirror-reflection lampshades, form shadowless lamp, but halogen tungsten lamp belongs to thermo-optical lamp, and little light Jiao of optically focused spot diameter is shallow, and bulb service life is short, easily makes people's visual fatigue.And LED lamp belongs to cold light source, very applicable use is on shadowless lamp, but in operating room, the light of shadowless lamp requires strictly, colour temperature, illumination, video picture index all to be had higher requirements.But the colour rendering of LED light is poor, and white-light spectrum is narrower, and LED lamp also has the low shortcoming of the video picture index that colour temperature is high colour temperature low, that video picture index is high, uses separately or simple multiple repeated arrangement is used the industry standard that all can not reach shadowless lamp.
Summary of the invention
Object of the present invention is exactly for the existing deficiency of prior art, solves traditional LED lamp and can not meet shadowless lamp manufacture requirement, and a kind of LED shadowless lamp is provided.
This programme is achieved by the following technical measures: a kind of LED shadowless lamp, it comprises circular lamp housing, in lamp housing, be provided with several LED lamp plates, lamp plate is provided with the control circuit of LED lamp, and it is two kinds of LED lamps that 4000K and colour temperature are 6500K that the LED lamp on described lamp plate includes colour temperature; In described lamp housing, be laid with ringwise six fan-shaped lamp plates, described lamp plate is provided with four row LED lamps, is outwards laid with successively one, two, three, four LED lamp by fan-shaped center; Each row LED lamp on described six lamp plates forms four concentric circles in lamp housing; On described each lamp plate, one of the 1st row, two of the 2nd rows, the 4th four of rows arrange the LED lamp that colour temperature is 4000K, and the 3rd three of rows are the LED lamp of colour temperature 6500K.
In order to regulate the hot spot focal length of shadowless lamp, described lamp plate is arcs of recesses, and one end and the lamp housing of lamp plate are hinged, is movable end in lamp housing center-side, and movable end is provided with adjusting knob can regulate light focusing position by the swing that regulates lamp plate.
The beneficial effect of this programme can be learnt according to the narration to such scheme, adopts LED lamp group, and power is little, and brightness is high, and the lamp group life-span is long.The LED lamp colour rendering index 93 that in the present invention, colour temperature is 4000K, total 7*6=42; Colour temperature is the LED lamp colour rendering index 78 of 6500K, total 3*6=18.Two kinds of mutual combined crosswise of LED lamp are used, and can reach the basic standard of operation shadowless lamp.Overall colour temperature is regulated within the scope of 4000K-5000K, and illumination reaches 160000lx, colour rendering index 90.Reach YY0627-08 operation shadowless lamp and the requirement of diagnosis illuminating lamp secure private completely.The present invention combines simply, is conducive to batch production, has larger practicality, and as can be seen here, the present invention compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 structural representation of the present invention.
In figure, 1, the LED lamp of colour temperature 4000K, 2, the LED lamp of colour temperature 6500K, 3, lamp plate, 4, lamp housing, 5, adjusting knob.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
The specific embodiment: as shown in Figure 1, a kind of LED shadowless lamp, it comprises circular lamp housing 4, is provided with several LED lamp plates 3 in lamp housing 4, lamp plate 3 is provided with the control circuit of LED lamp, 2 two kinds, the LED lamp 1 that the LED lamp on described lamp plate 3 comprises colour temperature 4000K and the LED lamp of colour temperature 6500K; In described lamp housing 4, be laid with ringwise six fan-shaped lamp plates 3, lamp plate 3 is provided with four row LED lamps, is outwards laid with successively one, two, three, four LED lamp by fan-shaped center; Each row LED lamp on described six lamp plates 3 is at four concentric circles of the interior formation of lamp housing 4.On each lamp plate one of the 1st row, two of the 2nd rows, the 4th four of rows colour temperature is set is that three of LED lamp 1, the 3 rows of 4000K are the LED lamp 2 that the LED lamp 2, of colour temperature 6500K has 1 and 18 colour temperature 6500K of LED lamp of 42 colour temperature 4000K.Described lamp plate 3 is arcs of recesses, and one end of lamp plate 3 and lamp housing 4 are hinged, is movable end in lamp housing 4 center-side, and movable end is provided with adjusting knob 5 can regulate light focusing position by the swing that regulates lamp plate.
