Focusing light intensity enhancing device for operating lamp

Abstract

The invention relates to a focusing light intensity light intensity enhancing device for an operating lamp. The device comprises a suspending or supporting system, and one or a plurality of lamp holders carried by the suspending or supporting system, wherein each lamp holder comprises a group of housings, one or a plurality of handles, a plurality of light resources, a focusing mechanism, a focusing detection device and an automatic light intensity compensation mode; the one or plurality of handles are arranged on the housing and used for holding or moving the lamp holder to a suitable position; the one or plurality of light resources are arranged in the housing for illumination; the focusing mechanism is used for adjusting the illumination focal length; the focusing detection device is used for sensing the position of the focusing mechanism within a variable range; the automatic light intensity compensation mode can be used for automatically enhance or reduce the light intensity of the light resource. Therefore, the focusing mechanism can be used for setting light ray focal length of each light resource; a set focal length range can be sensed by the focusing detection device, once the right range is changed, and the light ray focal length and the light intensity of each light resource can be adjusted automatically, so that the effects of automatic detection and automatic light intensity enhancing can be achieved.

Description

technical field [0001] The invention relates to a focusing photometric reinforcement device for an operating light, especially a related controller that can be used as the light source of the operating light. Background technique [0002] The known operating light adjusts the focus of illumination by changing the relative position of the light source of the lamp head and the reflector, or synchronously changing the angles of multiple lamp heads. [0003] When the focus of the operating light illumination changes, the diameter of the lighting range of the lamp head can be changed on the same focal plane, or the relative distance between the focus plane and the lamp head can be changed. Since the illuminance is inversely proportional to the square of the diameter of the lighting range and the lighting distance, therefore When the diameter of the illumination field increases or the focal plane is pulled away, the illumination of the surgical light in the surgical field will be ...

Problems solved by technology

[0004] Take the focal length transformation of the operating lamp illumination disclosed by the combination of US Invention Publication No. 2002 / 0145885 and Publication No. 2005 / 0052875 as an example. It can only increase the diameter of the lamp head reflector in the illumination range, or intercept the Relative light energy, but unable to increase the illuminance of the surgical light in the surgical area, which does cause inconvenience in actual use
