Abstract
The utility model relates to an operating shadowless lamp, which comprises a lampshade. The utility model is characterized in that the lampshade is provided with 50 to 200 LED units. The utility model has the advantages of high shadowlessness, low temperature rise and long service life.
Description
Technical field
The utility model relates to a kind of operation shadowless lamp light source, is applicable to operation, belongs to the lamp source technical field.
Background technology
The primary effect of operation shadowless lamp is the shade of eliminating in the operation, reduces the temperature rise of operating field.Traditional cellular type shadowless lamp adopts 3～12 incandescent lamp bulbs or based on halogen bulb as light source usually, and by the reflective mirror reflection, so light also is 3～12 times at the stacking fold of operating field; Common overall reflective shadowless lamp usually adopts 1 based on halogen bulb as light source, and the curved surface quantity by reflective mirror decides the stacking fold of light at operating field, and what adopt usually is that 8～12 curved surfaces carry out the stack of light at operating field; In addition, many minute surfaces overall reflective shadowless lamp also is to adopt 1 based on halogen bulb as light source, but reflective surface is nearly more than 1000, and no shadow degree is higher.The light efficiency of incandescent lamp bulb or based on halogen bulb is lower, and the life-span is shorter; Spectral characteristic shows more infrared ray, therefore heat is higher, need take to absorb or intercept the infrared ray measure during use, usually adopt that optical coating intercepts, antisolar glass absorbs or adopt plated film and antisolar glass to intercept simultaneously and absorb and reduce the operating field temperature rise, simultaneously traditional cellular type shadowless lamp and common overall reflective shadowless lamp light are few at the stacking fold of operating field, cause no shadow degree not high.
Summary of the invention
The purpose of this utility model provides a kind of no shadow degree of operation shadowless lamp, operation shadowless lamp of control operating field temperature rise of increasing.
For realizing above purpose, the technical solution of the utility model provides a kind of operation shadowless lamp, comprises lampshade, it is characterized in that, is provided with 50-200 LED unit on lampshade.
Described LED unit is formed by LED lamp and lens or with reflective mirror, and the LED lamp is located at the upper end of lens or reflective mirror, is positioned on the axis of lens or reflective mirror.
The utility model with the no shadow degree that increases quantity of light source and improve operation shadowless lamp, need not to take to absorb or intercept the infrared ray measure and control the operating field temperature rise.
Light source of the present utility model adopts white large-power light-emitting diodes LED, each LED focuses on by corresponding lens or corresponding reflective mirror, adopt the combination of 50-200 LED, make through the light after focusing on to superpose at operating field from different perspectives, reach no shadow.
Adopt white large-power light-emitting diodes LED, have higher colour rendering and luminous efficiency, when the light of She Chuing shines the same area from different directions, can eliminate shade, the effect of the stack elimination shade of many more light is good more and heat is low, the life-span is long, has controlled the operating field temperature rise effectively.
The utility model has the advantages that no shadow degree height, temperature rise is low, and the life-span is long.

Fig. 2 is diode (LED) and lens combination structure schematic diagram;
Fig. 3 is diode (LED) and reflective mirror combining structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be operation shadowless lamp light-source structure schematic diagram, described a kind of operation shadowless lamp is made up of lampshade 1 and LED unit 2, and 50 LED unit 2 are housed on lampshade 1, from different perspectives operating field is shone, and reaches no shadow effect.
Process lens or reflective mirror earlier, each LED and lens or reflective mirror are carried out the synthetic LED unit 2 of assembled group, described LED unit 2 is made up of LED lamp 6 and lens 7, and as shown in Figure 2, LED lamp 6 is located at the upper end of lens 7, or form with reflective mirror 8, as shown in Figure 3, LED lamp 6 is located at the upper end of reflective mirror 8, is positioned on the axis 5 of lens 7 or reflective mirror 8, light 3 scioptics, 7 refraction backs or reflective mirror 8 reflection backs form irradiation hot spot 4 in the regulation zone, and superposeing at operating field reaches no shadow.
Forming the LED unit for two kinds can be used in combination separately separately, also can simultaneously and deposit use.
