Light path structure for operating astral lamp

Abstract

The invention provides an optical path structure used for an operating shadowless lamp, comprising a lamp body with an axes, at least one first LED light source group and at least one second LED light source group; the first LED light source group surrounds the axes of the lamp body; furthermore, a vertical angle is preset on the optical paths of the first LED light source group; the second LED light source group surrounds the first LED light source group; furthermore, the angle of the optical path of the second LED light source component group is adjustable, thus increasing the incident angle of the optical path; more especially, the operating shadow can be effectively eliminated during deep operating illumination; compared with the prior art in which the optical path which is converged from circumference to axes is provided, the central position of illumination can form a vertically incident optical column, thus excellently solving the problem of deep illumination and leading the adjustment of focusing depth to be relatively easy, thereby greatly facilitating the doctors.

Description

technical field [0001] The invention relates to a shadowless operating lamp technology, in particular to an optical path structure of the shadowless operating lamp. technical background [0002] With the advancement of science and technology and the improvement of medical conditions, a variety of existing medical equipment plays an extremely important role in various fields, especially when doctors perform operations on patients, surgical shadowless lamps are indispensable as lighting equipment. , Surgical shadowless lights are widely used whether in the operating room of the urban central hospital or in the operating vehicle of the field hospital. [0003] During the operation, the theoretical distance between the focal surface of the surgical wound and the lamp surface of the surgical shadowless lamp is 1 meter, but in the actual operation process, due to the installation position or use angle of the surgical shadowless lamp, the needs of various operations , and the doct...

AI Technical Summary

Problems solved by technology

However, since the light of this kind of surgical shadowless lamp is converged and superimposed from the surrounding to the central axis through the reflection of the multi-faceted mirror, when the focus plane moves up and down, the light spot will often appear uneven due to the change of the superimposition times of the light. The depth and the degree of shadowlessness will also be affected, especially in the operation of deep wounds, only relying on the light path that converges and superimposes from the surrounding to the central axis will easily form shadows on the inner wall of the surgical wound, which will affect the doctor's observation. Identification and Surgical Implementation

[0004] In the prior art surgical shadowless lamps, there are also multiple light sources used to achieve shadowless lighting effects, that is, perforated surgical shadowless lamps, such as 5 holes, 8 holes, or 12 holes, etc. However, although this kind of perforated surgical shadowless lamps change The multi-faceted mirror technology in the overall reflection shadowless lamp is adopted, but the light is still converged and superimposed from the surrounding to the central axis, and it is also difficult to completely eliminate the shadow deep in the wound, and it is still not easy to adjust the depth of focus Adjust the light focus point to the best position
