Preheating method for xenon lamp light source of endoscope, xenon lamp light source and endoscope

Abstract

The invention provides a preheating method of an endoscope xenon lamp light source, a xenon lamp light source and an endoscope, the method can determine the target brightness of the endoscope xenon lamp light source and collect the real-time brightness of the endoscope xenon lamp light source in the preheating process, and the endoscope xenon lamp light source can be preheated when the real-time brightness of the endoscope xenon lamp light source is larger than or equal to the target brightness. When the endoscope xenon lamp light source is preheated, it can be prompted that the preheating progress of the endoscope xenon lamp light source is completed, at the moment, in the process of preheating the endoscope xenon lamp light source, the completion of the preheating progress can be fed back timely and accurately, and therefore it can be guaranteed that the endoscope xenon lamp light source is fully preheated, and meanwhile waste of working time caused by blind waiting after full preheating is avoided; the light emitting effect of the endoscope xenon lamp light source is guaranteed, and the preheating efficiency of the endoscope xenon lamp light source is also improved.

Description

technical field [0001] The invention relates to the technical field of xenon lamp light sources, in particular to a method for preheating an endoscope xenon lamp light source, a xenon lamp light source and an endoscope. Background technique [0002] Xenon lamp is an electric light source that emits light through xenon gas discharge. Its radiation spectrum energy distribution is close to that of sunlight. It is widely used as artificial light source and used in photography, copying, medical treatment, photovoltaic testing and other fields. [0003] The xenon lamp usually needs to be preheated to make its brightness reach the brightness required by the work. The preheating time may vary according to the work and environmental conditions. For example, the xenon lamp in the endoscope usually needs to be preheated for about 20 minutes. The warm-up of the xenon lamp is considered complete when the preset time is reached. [0004] However, the preheating time can only reflect the ...

Problems solved by technology

[0004] However, the preheating time can only reflect the length of the xenon lamp preheating process, but not the state change of the xenon lamp during the preheating process. It may happen that the xenon lamp has been preheated before the end of the preheating time and can be put into work. However, the xenon lamp is put into work after the warm-up time is over, resulting in a waste of working time, or, the xenon lamp has not been warmed up after the warm-up time is over, so that the brightness of the xenon lamp cannot meet the work requirements, such as using the xenon lamp as a cold light source for an endoscope Insufficient brightness of the xenon lamp makes the imaging brightness low and the definition poor, which affects the imaging effect of the endoscope
