Description
Technical field
The utility model relates to medicine equipment, particularly a kind of medical examining lamp.
Background technology
Medical examining lamp, that is diagnosis illuminating lamp are the secondary light sources of lighting for medical use or diagnosis.What existing medical examining lamp generally adopted is matrix LED light emitting source, and because LED is matrix distribution, lens also adopt acrylic Integrated design mostly, all have higher requirements to optical design, mould, machined and assembly technology.Matrix LED light emitting source has multiple focusing unit, easily occurs plum blossom-shaped blackening in the hot spot that the light sent is formed by it, is difficult to obtain the hot spot even, mellow and full, size is adjustable.
Utility model content
The purpose of this utility model to provide a kind of new medical inspecting lamp, and what can solve in above-mentioned prior art problem is one or more.
According to an aspect of the present utility model, provide a kind of medical examining lamp, comprise light-emitting device, the first convex lens, iris ring and the second convex lens; The light that light-emitting device sends is successively through the first convex lens, iris ring and the second convex lens.
The light that the light-emitting device of medical examining lamp of the present utility model sends after the first convex lens converge, then can obtain the hot spot of inner homogeneous through the second convex lens.Between the first convex lens and the second convex lens, be provided with adjustable aperture, by regulating the size by the luminous flux of iris ring 4, the size of hot spot can be regulated, and make hot spot mellow and full.
In some embodiments, the distance of light-emitting device of the present utility model and the first convex lens is less than the focal length of the first convex lens.Thus, the light that light-emitting device sends as often as possible can be converged, improve the utilization rate of light.
In some embodiments, the utility model also comprises the lamp housing holding light-emitting device, the first convex lens, iris ring and the second convex lens, and adjustable ring and the lamp housing of iris ring periphery are rotationally connected.Like this, when adjustment iris ring, operate more convenient.
In some embodiments, light-emitting device of the present utility model is LED.Use LED as light source, relative energy-saving, environmental protection.
In some embodiments, LED rear portion of the present utility model is provided with fin.LED luminescence can produce a large amount of heats, arranges fin heat can be made to be shed as early as possible at its rear portion, can not service life of agglomeration economies LED.
In some embodiments, the power of LED of the present utility model is greater than 0.5 watt.As the light source of medical examining lamp, adopt the LED being greater than 0.5 watt could obtain enough illuminations.
Accompanying drawing explanation
Fig. 1 is the structural representation of the medical examining lamp of a kind of embodiment of the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 show schematically show the structure of the medical examining lamp of a kind of embodiment of the utility model.
As shown in Figure 1, this medical examining lamp comprises the light channel structure that light-emitting device 7, first convex lens 3, iris ring 4 and the second convex lens 5 are formed.The light that light-emitting device 7 sends is successively through injection after the first convex lens 3, iris ring 4 and the second convex lens 5.
The light that light-emitting device 7 sends, after the first optically focused of the first lens 3, is regulated the size of luminous flux, then projects required uniform light spots through the second lens 5 by iris ring 4.
The light that light-emitting device 7 sends after the first convex lens 3 converge, then can obtain the hot spot of inner homogeneous through the second convex lens 5.Between the first convex lens 3 and the second convex lens 5, be provided with adjustable aperture 3, by regulating the size by the luminous flux of iris ring 4, the size of hot spot can be regulated, and make hot spot mellow and full.
It is inner that light-emitting device 7, first convex lens 3, iris ring 4 and the second convex lens 5 are arranged on lamp housing 2.
In the present embodiment, the distance of light-emitting device 7 and the first convex lens 3 is less than the focal length of the first convex lens 3.The light that light-emitting device 7 sends as often as possible can be converged like this, improve the utilization rate of light.In other embodiments, the distance between light-emitting device 7 and the first convex lens 3 also can be set as required.If the lighting angle of light source is large, the distance between light-emitting device 7 and the first convex lens 3 should be closer; If the lighting angle of light source is little, the distance so between light-emitting device 7 and the first convex lens 3 can be suitably far away.
In the present embodiment, the adjustable ring 6 of iris ring 4 periphery is rotationally connected with lamp housing 2.Like this, when adjustment iris ring 4, operate more convenient.In other embodiments, also a jut can be set in iris ring 4 periphery, by back and forth pulling jut to regulate the logical light quantity by iris ring 4.The aperture that iris ring 4 can adopt the specialty optics utensils such as optical camera to use.
In the present embodiment, the first convex lens 3 and the second convex lens 5 are all the set of lenses respectively containing two panels convex lens.In other embodiments, the first convex lens 3 and the second convex lens 5 also can be only have monolithic convex lens, or have the set of lenses of convex lens of the quantity such as three, four.First convex lens 3 can be different from the quantity of the convex lens that the second convex lens 5 contain separately.
In the present embodiment, light-emitting device 7 is LED, can be COB area light source or single led.LED rear portion is provided with fin.LED luminescence can produce a large amount of heats, arranges fin and heat can be made to be shed as early as possible, can not affect the service life of LED because heat gathers at its rear portion.Use LED as light source, relative energy-saving, environmental protection.In other embodiments, light-emitting device 7 also can adopt other light source such as incandescent lamp or Halogen lamp LED.
LED is fixed on the lamp holder pedestal 1 of lamp housing 2 one end, and lamp holder pedestal 1 can adopt heat-dissipation aluminum sectional material, also can be provided with large-area fin.
The power of LED should be greater than 0.5 watt.As the light source of medical examining lamp, adopt the LED being greater than 0.5 watt could obtain enough illuminations.The requirement of structure of the present utility model to the lighting angle of LED light emitting source is lower, and lighting angle is 90 ° ~ 140 ° and all can normally uses.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
