Light resource device and lamp service life detection method for endoscope

Abstract

The invention discloses a light resource device and a lamp service life detection method for an endoscope. The device comprises at least one group of light sources, driving control units having the same number as the group number of the light sources, an optical path synthetic unit, a lamp detection unit and a system control unit. The method comprises the following steps of: receiving light signals from the light sources and converting the light signals into data representing light intensity; and judging whether the data representing the light intensity is lower than the preset lamp service life threshold or not, if so, sending alarming information. Due to the adoption of the embodiment of the invention, the service life of a lamp can be timely and accurately known and a user is prompted to timely change the lamp which reaches the end of the service life, so the phenomenon of abnormity of the lamp in an endoscope detection period is avoided; and the realization way is simple, so the light resource device is more acceptable by a patient.

Description

technical field [0001] The invention relates to the technical field of light sources of endoscopes used in medical treatment, in particular to a light source device for endoscopes and a lamp life monitoring method. Background technique [0002] With the development of endoscopes (including ordinary endoscopes and electronic endoscopes) and the improvement of people's requirements for diagnosis, it is hoped that the endoscope light source device that provides illumination can have uniform and adjustable brightness, lower power consumption, and low cost. . Traditional endoscope light source devices all use a high-power halogen lamp or xenon lamp as the main light source, and a high-brightness light-emitting diode (LED) lamp as the backup light source. The main light source works at full power when it is turned on, and the luminous flux is adjusted by adjusting different apertures on the optical path, and then the brightness of the light is adjusted. [0003] Since the light ...

Problems solved by technology

[0006] It can be seen that both of the above two methods use an indirect method to detect the life of the lamp, and neither can accurately detect whether the light source is really invalid. In this way, it may cause waste of the lamp due to premature replacement of the light source, and it may also be caused by the exhaustion of the light source. The impact of changing the light source on the final image quality
