Abstract

The invention discloses an intelligent light adjustment system for an LED shadowless lamp based on ultrasonic positioning, and the system comprises a main control board, a light induction sensor, an ultrasonic sensor array, an ultrasonic control board, a distance measurement positioning module, an illumination analysis module, a communication module, an ARM processor, an interface control module, an LED control board, an LED light source module, and an LCD touch screen unit module. The system is formed by the construction of an embedded-type processor, a photoelectric sensor and the supersonic positioning detection technology, and takes an ARM microprocessor as the core. The system employs the photoelectric sensor and the ultrasonic sensing technology to achieve the closed-loop control. The system employs the supersonic positioning technology to detect the spatial position of an operative region sheltering object, and achieves the control of a plurality of LED arrays through an embedded microprocessor system, thereby achieving the adaptive light adjustment of the shadowless lamp, achieving the real-time adjustment of the illumination position and brightness of the shadowless lamp, eliminating the shadow of a working plane, and enabling the illuminance of a light spot to be uniform and constant.

Description

technical field [0001] The invention relates to a special medical lighting equipment, in particular to an intelligent dimming system of an LED shadowless lamp. Background technique [0002] Surgical shadowless lamp is one of the necessary important medical equipment in the hospital operating room. Whether its light position and brightness can be adjusted in time will affect the normal operation of the operation. In addition, the brightness and shadowless performance of the surgical shadowless lamp are directly related It is related to the quality of surgery and the health of patients; traditional shadowless lamps are mostly adjusted manually, which is manually adjusted by the operator according to his own comfort, and the accuracy of the brightness is difficult to guarantee, which has great limitations. During the operation, the doctor's head, hands and instruments will block the operation area and form a shadow. If it is not removed in time, it will definitely affect the no...
