Circuit control system for LED shadowless lamp of digital operating room

Abstract

The invention discloses a circuit control system for an LED shadowless lamp of a digital operating room. The circuit control system comprises a microprocessor, a mode conversion circuit and a communication control circuit, wherein a power processing module is arranged at an input end of the microprocessor and a signal processing circuit is arranged at an output end; the other end of the signal processing circuit is connected with an LED drive signal output circuit through the mode conversion circuit; the LED drive signal output circuit is branched into a pure white light LED drive signal output circuit, a cold light LED drive signal output circuit, a warm light LED drive signal output circuit and a special LED drive signal output circuit for a pure white endoscope; an obstacle detection module interface and a light spot position sampling circuit are also arranged at the input end of the microprocessor; and a drive control interface and an electric focusing circuit are arranged at the output end of the microprocessor. The circuit control system has three communication modes and five working modes, stepless dimming or light adjustment of any gear can be achieved under the five working modes and the circuit control system also has an automatic light occlusion detection function.

Description

technical field [0001] The invention relates to a circuit control system, in particular to a circuit control system for digital operating room LED shadowless lamps. Background technique [0002] In recent years, the operating room equipment of major hospitals is developing in the direction of integration, intelligence and digitization. However, due to the independence of its control, the traditional LED surgical shadowless lamp can only be controlled and operated on the control panel, and cannot realize integrated and intelligent management control and maintenance. In addition, the existing LED surgical shadowless lamp also has the following defects: 1) Generally, the size of the shadowless light spot is manually adjusted through the disinfection handle, which cannot realize intelligent control and is not convenient to operate; even if there is an electric focusing method, it is also based on artificial The control of the jog button cannot achieve accurate digital adjustmen...

However, due to the independence of its control, the traditional LED surgical shadowless lamp can only be controlled and operated on the control panel, which cannot realize integrated and intelligent management control and maintenance.

In addition, the existing LED surgical shadowless lamp also has the following defects: 1) Generally, the size of the shadowless light spot is manually adjusted through the disinfection handle, which cannot realize intelligent control and is not convenient to operate; even if there is an electric focusing method, it is also based on artificial The control of the jog button cannot achieve accurate digital adjustment; 2) The circuit structure is simple, it is difficult to realize the simultaneous existence of color temperature adjustment, cavity mirror mode, and bright mode, and the traditional color temperature adjustment generally only uses two series of high and low color temperatures Changes in the color temperature of lamp beads and color temperature can easily cause changes in illuminance; 3) Traditional LED shadowless lights are generally controlled as a whole and do not have the function of automatically detecting light occlusion, so that the light utilization rate is not high, and when there is a lot of occlusion, the illumination of the central spot will drop seriously.
