Abstract
A reflector for shadowless lamp is uses a group of serially connected annular conical reflectors with different angles relative to horizontal plane to form a conical step-type structural element, wherein the inclination of each reflector confirms an annular spot of same size reflected from the reflector on one basic radiation plane, and all annular spots are laminated into a focus spot. The reflector can form a focus spot of same diameter when the distance between the reflection plane and the radiation plane changes, prevent the position adjustment of light source, and can reduce shadow, thereby being beneficial to the medical operation.
Description
Technical field
The utility model relates to a kind of medicine equipment, relates in particular to a kind of reflector that is used for shadowless lamp.
Background technology
Operation shadowless lamp in actual use, its reflective surface has to the distance of shadow surface closely to be had far, thereby the diameter dimension of focal beam spot also can respective change.Existing operation shadowless lamp is owing to its structural reason, when the distance of shadow surface changes, keep certain spot diameter at reflective surface, needs to adjust the position of light source (bulb) in reflector.This part work is carried out in surgical procedure by the doctor, causes operational inconvenience.The optical principle of existing reflector as shown in Figure 1, reflector 9 has only a focus point along central optical axis 10, after departing from basic focusing surface 11, hot spot can become (shown in 12) greatly, keep the hot spot of certain size, then requires the position of adjustment light source 13.
The utility model content
The purpose of this utility model is exactly in order to provide a kind of reflector that is used for shadowless lamp that need not to adjust the position of light source in reflector.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of reflector that is used for shadowless lamp, become the annular tapered surface reflective mirror of different angles to be linked in sequence into the ladder-type structure spare that an integral body is cone shape with horizontal plane by one group, the angle of inclination of each annular tapered surface reflective mirror guarantees that the light of its reflection forms the basic the same ring-shaped light spot of size at same basic shadow surface, and focal beam spot is formed in each ring-shaped light spot stack.
The angle of inclination of described each annular tapered surface reflective mirror is 1 meter design according to its basic shadow surface apart from the vertical range of light-emitting area all.
When reflector of the present utility model was applied to the operation shadowless lamp of hospital operating room use, light converged to apart from the basic shadow surface of 1 meter of light-emitting area from the shadowless lamp light-emitting area is tapered, formed the focal beam spot of a circle.When doctor's head shoulder check a part of reverberation when producing shade at the focal beam spot place, the retrodirected ray of taper reflection ray can compensate it, thereby can weaken shade.At reflective surface not simultaneously, still can form the essentially identical focal beam spot of diameter, need not adjust light source position, and can weaken shade equally to the shadow surface distance.

Fig. 2 is the structural representation that the utility model is used for the reflector of shadowless lamp;
Fig. 3 is the optical principle schematic diagram of the utility model reflector.
The specific embodiment
Referring to Fig. 2, Fig. 3, the utility model is used for the reflector 1 of shadowless lamp, become the annular tapered surface reflective mirror 2 of different angles to be linked in sequence into the ladder-type structure spare that an integral body is cone shape with horizontal plane by one group, the angle of inclination of each annular tapered surface reflective mirror guarantees that the light of its reflection forms the basic the same ring-shaped light spot of size at same basic shadow surface 3, and focal beam spot 4 is formed in each ring-shaped light spot stack.
In the present embodiment, the angle of inclination of each annular tapered surface reflective mirror is 1 meter design according to its basic shadow surface apart from the vertical range of light-emitting area all.
The utility model be used for shadowless lamp reflector optical principle as shown in Figure 3, each annular cones face reflective mirror 2 has the focus point of different distance along central shaft 5, after light is sent by light source 6, after each annular cones face reflective mirror 2 reflections of reflector 1, form the reflection light beam 7 angled respectively with central shaft 5.The angle of inclination of each annular tapered surface reflective mirror is 1 meter design according to its basic shadow surface apart from the vertical range of light-emitting area all in the reflector, make its reverberation on the basic shadow surface 3 at 1 meter of distance light-emitting area, be converged to focal beam spot 4, produce a general character hot spot very nearly the same in the certain distance up and down at shadow surface simultaneously, form a convergence light beam 8 with certain depth and certain spot diameter by these general character hot spots with this focal beam spot diameter.So, at reflective surface (greater than 1 meter or 1 less than rice) when the shadow surface variable in distance, as long as shadow surface drops in the scope of assembling light beam 8, still can form the essentially identical focal beam spot of diameter, need not adjust light source position, and can weaken shade equally, greatly facilitate medical worker's operation.
Claims (2)
1. reflector that is used for shadowless lamp, it is characterized in that: become the annular tapered surface reflective mirror of different angles to be linked in sequence into the ladder-type structure spare that an integral body is cone shape with horizontal plane by one group, the angle of inclination of each annular tapered surface reflective mirror guarantees that the light of its reflection forms the basic the same ring-shaped light spot of size at same basic shadow surface, and focal beam spot is formed in each ring-shaped light spot stack.
2. the reflector that is used for shadowless lamp as claimed in claim 1 is characterized in that: the angle of inclination of described each annular tapered surface reflective mirror is 1 meter design according to its basic shadow surface apart from the vertical range of light-emitting area all.
