In the operating room of major hospitals, the application of LED surgical shadowless lamp can be described as extremely common, the so-called shadowless lamp, simply put, is composed of multiple lamp heads, fixed on the balance arm suspension system, can meet the needs of different lighting heights and angles in the operation of a class of equipment. In order to deepen everyone's understanding of LED surgical shadowless lamp products, this article will briefly introduce the unique technical highlights of LED surgical shadowless lamp compared with traditional surgical lamp, I hope you will be interested.
LED surgical shadowless light consists of a five-dimensional positioning mechanism, an LED array cold light source with a power converter and a regulator, a CCD camera, and a higher-level computer, under the control of the upper-computer computer, the five-dimensional stepper motor moves according to the given digital amount, so that the light source reaches the required accurate position and tilts to the exact angle. Set the functions of group adjustment, group adjustment, and single adjustment of the LED light source, and the illuminance of the LED corresponds to different current setting points, and the output PWM duty cycle is controlled. Based on CCD camera image tracking, real-time detection of shadows caused by occlusion objects in the illuminated area, and automatic adjustment of LED illuminance to achieve the purpose of eliminating shadows. Its high degree of automation, the realization of digital positioning and dimming functions, with high technology, specifically, the innovation point of LED surgical shadowless lamp is mainly manifested in the following aspects:
1. LED surgery shadowless lamp adjustable switch is set on the mobile bracket, the arm of the horizontal extension of the mobile bracket is fixed with a concentrator, the concentrator is composed of a focusing mechanism with a handle, a lamp plate, the bottom surface of the lamp disk is a downward concave spherical surface, several heat dissipation seats equipped with lens groups are distributed on the bottom surface of the lamp plate, at least 3 lamp plates are distributed at an equal distance around the focusing mechanism, the lamp plate and the focusing mechanism are hinged by hinges: the heat dissipation seat is fixed with an LED driver controller, The power converter and the backup power supply are connected to the input end of the power switch, the output end of the power switch is connected to the LED drive controller and the adjustable switch, the adjustable switch is connected in series with the LED drive controller, and the LED driver controller is electrically connected to several high-power LED chips in series.
2. The focusing mechanism with handle includes a screw nut mechanism and a connecting rod, wherein a screw nut mechanism is provided on the handle, one end of the connecting rod is connected with the light plate, and the other end is hinged with the screw nut mechanism. The ball arc radius of 1m on the bottom surface of the lamp plate is the mounting surface of the heat sink, the heat sink is distributed at equal distances on the mounting surface of the heat sink, and a lens group is provided in the center of the bottom surface of the lamp plate.
3. The LED surgery shadowless lamp lens group is composed of a high-power LED chip and a convex mirror, the high-power LED chip is fixed on the bottom surface of the heat dissipation seat, and the convex mirror is embedded on the top surface of the heat dissipation seat.
