The surgical shadowless lamp comprises a light source reference plate with a pointolite cardinal plane; a plurality of LEDs are arranged on the pointolite cardinal plane; the shadowless lamp also comprises a lens reference plate is provided with a plurality of lenses embedded in a lens cardinal plane; each lens corresponds to each LED on the pointolite cardinal plane; the lens cardinal plane is parallel to the pointolite cardinal plane; the distance between the lens cardinal plane and the pointolite cardinal plane is between 8 and 40 mm; the lenses are converging convex lens, and have the same specification. The surgical shadowless lamp mainly solves the problems that the structure of the prior product makes LED light sources project on the equidistant plane faculae with different diameters and consequently influences the distribution of faculas, lighting depth and other indexes; and the surgical shadowless lamp has the advantages of high illumination, low energy consumption, long service life, low irradiation, environmental protection and the like; in addition, the surgical shadowless lamp has good social and economic benefits and wide market prospect.
Description
Technical field
The present invention relates to a kind of medicine equipment operation shadowless lamp, especially a kind ofly be used for the operation shadowless lamp as light source with LED.
Background technology
At present, existing be used for operation shadowless lamp .LED with LED as light source and utilize electronics to move luminous, directly electric energy is converted to luminous energy, transformation efficiency is more than 5 times of incandescent lamp bulb up to 68%.Compare with halogen tungsten bulb commonly used putting LED, LED there are many advantages as the light source of shadowless lamp: the one, putting LED is real cold light source, under equal illumination, its emittance is lower than halogen tungsten bulb widely, that is to say with LED as the operation shadowless lamp of light source when being used for the operation illumination, people's injected organism tissue is not damaged at all; The 2nd, the LED heat energy loss is very low, and energy conversion efficiency is higher than general bulb, so more energy-conservation, more environmental protection; The 3rd, the service life of LED bulb is longer than common bulb, can reach 3 to 50,000 hours, is 100 times of halogen tungsten bulb.Because LED has many advantages, so the LED lamp is the inexorable trend of operation shadowless lamp development as a kind of new light source of operation shadowless lamp.
But existing LED operation shadowless lamp has following shortcoming:
1, a normally LED and combination of a lens formation of existing product, each is to relative position unanimity of combination, because the position in space is different, causes angle also to change thereupon.This can make that holder structure is complicated, and manufacturability is poor, and machining accuracy and difficulty significantly increase, and each led light source to project on the set a distance plane formed spot diameter also inconsistent, influence that hot spot distributes and index such as the illumination degree of depth.
2, the location of light source need be arranged on the different structures with heat radiation, has not only increased the complexity of structure, and has improved manufacturing cost.
Summary of the invention:
The objective of the invention is to a kind of operation shadowless lamp as light source that is used for LED, it is inconsistent that the structure that mainly solves existing product makes that each led light source projects on the set a distance plane formed spot diameter, influence the problem of indexs such as the hot spot distribution and the illumination degree of depth, it has it and has advantages such as high illumination, low energy consumption, long-life, low radiation, environment-friendly type, have good society and economic benefit, have vast market prospect.
For achieving the above object, the present invention is achieved in that
A kind ofly be used for the operation shadowless lamp as light source, it is characterized in that it comprises that one has the light source datum plate of spot light basal plane, a plurality of LED are installed on this spot light basal plane with LED; Also comprise a lens datum plate, this lens datum plate is embedded a plurality of lens on the lens basal plane, and each lens is corresponding one by one with LED on the spot light basal plane; Lens basal plane and distance the two between parallel with the spot light basal plane is 8mm-40mm; Described lens are the optically focused convex lens, and the specification unanimity of each lens.
Describedly be used for the operation shadowless lamp as light source, it is characterized in that described lens basal plane and optimum distance the two between parallel with the spot light basal plane is 20mm-25mm with LED.
Describedly be used for the operation shadowless lamp as light source, it is characterized in that this light source datum plate is that aluminium or aluminum alloy materials are made, simultaneously as heat sink with LED.
By technique scheme, the present invention has following advantage:
Advantages such as 1, the present invention has adopted colony's led light source basal plane and radiating surface and has been the scheme with one, and this plane had both solved heat dissipation problem, had solved the light source orientation problem again, and this makes this modulated structure succinctly reliable, and is easy to process, and cost of manufacture is low.
2, the present invention has adopted light source multiple spot colony basal plane and the parallel scheme of lens colony basal plane in light path design, can make and produce spot diameter overlapping hot spot of a size on the plane of all set a distances.This is the required effect of operation shadowless lamp just, though this result makes each LED spot light arrive the distance of hot spot face apart from different, but spot diameter is identical, this result makes all lens specifications parameters possibility that becomes in full accord again, thereby make this product manufacturability optimization, reduce the cost of large-scale production.Because this effect, leading indicators such as the illumination degree of depth of operating lamp and hot spot distribution are significantly improved, after tested:
LED operating lamp 12 hole operating lamps of the present invention
Illumination degree of depth 910-920mm 480mm
Hot spot distribution 55-56 51
