Intelligent light regulating touch-control-free LED operating shadowless lamp circuit control system

Abstract

The invention relates to an intelligent light regulating touch-control-free LED operating shadowless lamp circuit control system comprising a power supply input device and a power supply processing device which is used for processing the power supply input device. The power supply processing device is connected with a microprocessing device and an electrification indicating device. A channel selection device, an operation indicating device, a fault detection device, a working state display screen and a noncontact key detection device are connected on the microprocessing device. The channel selection device is connected with an LED driving device which is connected with the power supply processing device. The intelligent light regulating touch-control-free LED operating shadowless lamp circuit control system has the advantages of being simple in structure, practical in function, high in anti-interference capacity, stable in performance, low-carbon and environment-friendly and intelligent in design.

Description

technical field [0001] The invention relates to a circuit for circuit control of a surgical shadowless lamp, in particular to a circuit control system for a touch-free LED surgical shadowless lamp capable of intelligent dimming. Background technique [0002] At present, the general surgical shadowless lamp is still dominated by halogen bulbs, because of its high power, generally around 150W, high energy consumption, high heat generation, and elevated temperature in the surgical field. If the doctor’s head is close to the lamp for a long time, it will It is obvious that the temperature of the head is high, especially when the brightness is adjusted high. In addition, because the life of the halogen lamp is generally only about 2000 hours, it is often necessary to replace the bulb, which brings inconvenience to the use. Some hospitals have begun to gradually use LED surgery. The shadowless lamp replaces the traditional halogen-type surgical shadowless lamp. The LED light sourc...

[0002] At present, the general surgical shadowless lamp is still dominated by halogen bulbs, because of its high power, generally around 150W, high energy consumption, high heat generation, and elevated temperature in the surgical field. If the doctor’s head is close to the lamp for a long time, it will It is obvious that the temperature of the head is high, especially when the brightness is adjusted high. In addition, because the life of the halogen lamp is generally only about 2000 hours, it is often necessary to replace the bulb, which brings inconvenience to the use. Some hospitals have begun to gradually use LED surgery. The shadowless lamp replaces the traditional halogen-type surgical shadowless lamp. The LED light source type surgical shadowless lamp has the advantages of high luminous efficiency, energy saving, long life (more than 30,000 hours), and because it is a cold light source, the temperature rise of the surgical field is small. PWM control, there is
