Problems solved by technology

[0010] Existing lighting devices usually have a single lighting function and do not have a camera function (see utility model patent, a medical lighting device, application number: 92204340.X); in actual medical operations, experiments, shopping malls, supermarkets, underground coal mines, In the case of tunnels, residences and vehicle pedestrian passages, etc., when realizing lighting and simultaneous shooting, a separate camera device (such as a video camera, etc.) is often used to shoot on the spot. The cost of realizing lighting and simultaneous shooting is high, and good real-time shooting cannot be performed. Or the charge-coupled device (CCD) camera is fixed on the lighting device, but the light beam of the illumination light required by the synchronous camera lighting device cannot be satisfied and the beam of the camera collection light is coaxial, so it cannot be guaranteed that the camera and the lighting are the same area
Recently, some people have integrated the camera system and the lighting system together to realize a lighting device with a camera function, and the light beam of the lighting light is coaxial with the light beam collected by the camera. However, the camera lighting head is relatively heavy and the system is more complicated. And the system parameters are inconvenient to adjust

Abstract

The present invention relates to an adjustable camera illuminating apparatus, including three portions of main machine, camera illuminating head and terminal display. The camera shooting and illuminating are identical in optical axis, and its illuminating light intensity, depth of field and magnification ratio can be regulated.

Description

Technical field: [0001] The present invention is related to camera, in particular to an adjustable camera lighting device, a parameter adjustable lighting device with camera function. It is mainly used in medical operations, experiments, shopping malls, supermarkets, underground coal mines, tunnels, residential and vehicle pedestrian passages, etc. The parameters are convenient and adjustable for synchronous real-time camera and lighting. Background technique: [0002] In existing medical operations, experiments, shopping malls and supermarkets, underground coal mines, tunnels, residential and vehicle pedestrian passages, etc., lighting fixtures often do not have the camera function, but in some cases, it is desirable to be able to take pictures while lighting. In medicine, taking pictures while lighting can better collect important medical data, record the patient's symptoms or the doctor's operation process in real time, and facilitate medical identification; in coal mines...
