Led flash light integrates the wireless infra-red technology

Different models of control systems are different, but basically works the same electronic control system mainly consists of the following components (1) power supply circuit all parts for the printer to provide the control voltage. 220V AC power supply circuit by the rectifier, filter, transformer, for a green laser pointer to provide 24V, 5V DC operating voltage (2) interface circuit for the computer to establish communication with the printer. receiving computer data information, and convert it to a printer language, print to the printer control circuit to provide data interface circuit includes a microprocessor (CPU). memory (RAM / ROM). (3) the main control circuit is the main control circuit to receive data interface circuit , according to the command control of all printer devices to work together to complete the printing process. green laser pointer is on the basis of WAP technology service.(4) scan drive circuit will receive computer information generated by high-frequency oscillator laser beam, and control the scanning motor uniform rotation, driven scanning mirror, complete drum scanning exposure, so as to form electrostatic latent image (5) main motor drive circuit according to the directives issued by the main control circuit, driving the main motor rotation, the gears, the transmission of power to run the various parts of the work (6) high-pressure transfer circuit of the circuit is to provide low-voltage power supply circuit, provided by the transformer into a high voltage charging and transfer roller drum needed to transfer laser printer appears to be simple, but it combines sound, light, electrical and mechanical , chemical and many other high-tech. led flash light integrates the wireless infra-red technology.These are just a brief laser printer structure and working principle, the operator on the emotional understanding of the various parts of the printing system's role in the printer and laser imaging of the whole process of these work to solve the case in great help to the problem, especially the maintenance staff, if not fully understand the working principle of laser printer parts and functions, it would not "maintenance" word. Photonics photonics technology, Nankai University, Tianjin University Science and co-educational professional development in the field of photonics technology has a generous scientific theory, solid expertise and skilled experimental skills, moral, intellectual, physical, and aesthetic development of advanced photonics technology scientific talent, to make students have in optics, optoelectronics, laser science, optical communications technology, optical waveguides and optical integration technology, optical information processing technology, computer application technology and other areas of basic research and innovation in the design, application development and management should have green laser pointer integrates the wireless radio frequency technology.The theoretical and technical basis. The profession of "physics-based national training base," the Ministry of Education, "Optical Information Science and Technology" Key Laboratory of disciplines rely on high academic standards, strong teacher. 31 professors of the profession (including Chinese Academy of Sciences 2, 20 doctoral tutors, "Cheung Kong Scholars Program" Distinguished Professor of 4). Subjects covering four doctoral, master's degree 9, postdoctoral 3, 2 national key disciplines, is a national "211 Project" and "Education Promotion Plan" key construction disciplines, combined with training Polytechnic scientific complex photonics technology personnel advantages.green laser pointer integrates the cursor control technology.
