Embodiment 1
[0066] Embodiment one, with reference to Figure 1-8 , the embodiment of the present invention provides an LED lighting control system 100, including: a controller 101, a light metering probe 102 and a display 103; wherein, the light metering probe 102 is electrically connected to the controller 101; the display 103 It is electrically connected with the controller 101.
[0067] Due to the electrical connection between the light metering probe 102 and the controller 101, after the light metering probe 102 detects the brightness information in the film to be imaged, the brightness information can be transmitted to the controller 101, and the controller 101 can determine according to the brightness information For an appropriate exposure time, since the controller 101 is electrically connected to the display 103 , after the controller 101 determines the exposure time, the display 103 can be used to display the exposure time. Then the user can check the exposure time directly fro...

The invention discloses an LED light control system. The LED light control system comprises a controller, a photometric probe, a display and a light display gray scale strip. The photometric probe iselectrically connected with the controller. The photometric probe is used for detecting brightness information of a negative film to be imaged and transmitting the brightness information to the controller. The display is electrically connected with the controller. The display is used for displaying the exposure time transmitted by the controller. The light display gray scale strip is electricallyconnected with the controller. The light display gray scale strip is used for displaying the gray scale corresponding to the exposure time according to the triggering of the controller. According to the invention, multiple attempts do not need to be carried out on the photosensitive photographic paper in a manual mode, so that the efficiency of determining the exposure time is improved, the wasteof the photosensitive photographic paper is avoided, and meanwhile, the to-be-imaged negative film images the corresponding gray scale, so that a user can conveniently carry out operations such as later adjustment and the like, and the user experience is improved.
Description
technical field [0001] The invention belongs to the technical field of photography, and specifically relates to an LED light control system and an application method thereof. Background technique [0002] In the process of imaging through negatives, the negatives on the enlarging machine are projected through the lens onto the photosensitive paper under the lens through the light source to form images on the photosensitive paper. [0003] In order to make the image on the negative film appear clearly and beautifully on the photosensitive paper, it is necessary to set an appropriate exposure time. When adjusting the exposure time, generally set different exposure times first, then perform exposure flushing for the set exposure times one by one to obtain images corresponding to different exposure times, and then determine the ideal exposure time according to the clarity and aesthetics of each image . [0004] In the course of realizing the present invention, the inventor fin...
