Description

Light source device

Technical Field

The present disclosure relates to the field of illumination light sources, and in particular, to a light source device.

Background

The illumination sources can be generally divided into a source end and an illumination end. The source end converts the electric energy into light energy and emits a light beam. The illumination end adjusts the light beam emitted by the source end, such as light distribution and diffusion angle, to form illumination light.

In a conventional light source device, a source end and an illumination end are commonly packaged in a housing. In general, this is advantageous, for example, in that the overall size and volume can be reduced.

However, in some special occasions, such as security protection, search and rescue, mines, headlamps and the like, the light source device has the defect. Because the source end and the illumination end are integrated in a space as small as possible, the heat generated by the source end and the illumination end are superposed, the heating value of the device is large, and the requirement of heating value and even safety is difficult to meet.

One solution known is to separate the source end from the illumination end, i.e. photo-electrically. The source is typically placed in a particular location and the illumination end is coupled to the source by a light-guiding element having a length so as to direct a light beam generated by the source to the illumination end, which is independently applied to the target location relative to the source to perform the task. In this way, the source end and the illumination end realize photoelectric separation, the illumination end independently performs work at the above place relative to the source end, and only the illumination end generates heat at the place where the work is performed, so as to finally meet the requirement of heat productivity.

Any one of the source end, the illumination end and the light guiding element is abnormal by using the light source device with photoelectric separation, so that the whole device cannot work normally. For example, when a laser is used as the light emitting device, if light leakage occurs, it may even threaten the health of the human body. It can be seen that it is necessary to detect abnormality of the light source device in time.
