Abstract
The utility model relates to a medical illumination device, especially a shadowless lamp used in an operation, and in particular an LED shadowless lamp including a round lamp housing, wherein a plurality of LED lamp plates are arranged in the lamp housing, a control circuit for the LED lamps is arranged on the lamp plates, the LED lamps on the lamp plates includes two types of LED lamps which have 4000K color temperature and 6000K color temperature, the lamp plates are provided with four rows of LED lamps, one, two, three and four LED lamps are uniformly distributed in order from a sector center to the outside, and each row of LED lamps of the six lamp plates form four concentric circles in the lamp housing. The LED shadowless lamp employs LED lamp groups, the power is small, all the color temperature, illumination and colour rendering index or the like reach the standard code of the industry, and the service life of the lamp groups is long, the manufacture cost is low, thus the LED shadowless lamp has a certain popularization and usage value.
Description
Technical field
The utility model relates to medical illumination equipment, especially uses 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 a plurality of tiny mirror-reflection lampshades, form shadowless lamp, but halogen tungsten lamp belongs to hot light modulation, and little light Jiao of optically focused spot diameter is shallow, and bulb service life is short, makes easily people's visual fatigue.And the LED lamp belongs to cold light source, and very suitable use is on shadowless lamp, but the light of shadowless lamp is strict in the operating room, and colour temperature, illumination, video picture index are all had higher requirements.But the colour rendering of LED light is poor, and white-light spectrum is narrower, and the LED lamp also has the low shortcoming of the high video picture index of colour temperature colour temperature low, that the video picture index is high, uses separately or simple a plurality of repeated arrangement is used the industry standard that all can not reach shadowless lamp.
Summary of the invention
The purpose of this utility model is exactly for the existing deficiency of prior art, solves traditional LED lamp and can not satisfy shadowless lamp manufacturing 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, be provided with several LED lamp plates in the lamp housing, lamp plate is provided with the control circuit of LED lamp, and it is that 4000K and colour temperature are two kinds of LED lamps of 6500K that the LED lamp on the described lamp plate includes colour temperature; Be laid with ringwise six fan-shaped lamp plates in the described lamp housing, described lamp plate is provided with four row LED lamps, outwards is laid with successively one, two, three, four LED lamp by fan-shaped center; The LED lamp of respectively arranging on described six lamp plates forms four concentric circles in lamp housing; One of the 1st row, two of the 2nd rows, the 4th four of rows arrange the LED lamp that colour temperature is 4000K on described each lamp plate, 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 the circular arc of depression, and an end and the lamp housing of lamp plate are hinged, is movable end in the lamp housing center-side, and movable end is provided with adjusting knob can regulate the light focusing position by the swing of regulating 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.Colour temperature is the LED lamp colour rendering index 93 of 4000K in the utility model, 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.Whole colour temperature is regulated in 4000K-5000K scope, and illumination reaches 160000lx, colour rendering index 90.Reach YY0627-08 operation shadowless lamp and diagnosis illuminating lamp secure private requirement fully.The utility model combination is simple, is conducive to batch production, and larger practicality is arranged, and this shows that the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement also is apparent.
Description of drawings:
Fig. 1 structural representation of the present utility model.
Among the 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 the lamp housing 4, lamp plate 3 is provided with the control circuit of LED lamp, and the LED lamp on the described lamp plate 3 comprises 2 two kinds on the LED lamp of the LED lamp 1 of colour temperature 4000K and colour temperature 6500K; Be laid with ringwise six fan-shaped lamp plates 3 in the described lamp housing 4, lamp plate 3 is provided with four row LED lamps, outwards is laid with successively one, two, three, four LED lamp by fan-shaped center; Respectively arrange the LED lamp at four concentric circles of lamp housing 4 interior formation on described six lamp plates 3.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 that the LED lamp 2, of colour temperature 6500K has the LED lamp 1 of 42 colour temperature 4000K and the LED lamp 2 of 18 colour temperature 6500K.Described lamp plate 3 is arcs of recesses, and an end and the lamp housing 4 of lamp plate 3 are hinged, are movable end in lamp housing 4 center-side, and movable end is provided with adjusting knob 5 can regulate the light focusing position by the swing of regulating lamp plate.
