Problems solved by technology

[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 a certain frequency, which will interfere with some medical instruments with cameras, causing stripes to run, and it is easy to cause visual fatigue after the doctor's eyes look at it for a long time; on the other hand, conventional circuits do not have intelligent dimming technology. If the doctor's head is close to the light source to block the light, it will cause the brightness of the operation area to drop. At the same time, the blocked lamp bead light source is not used correctly, which will also cause some temperature rise to the doctor's head; moreover, almost all current The dimming of shadowless lamps is controlled by buttons or touch screens. This kind of control is contact type. Because buttons and touch screens are generally not easy to be sterilized, there are easy bacteria residues, and there is a certain risk of secondary infection, and there is a certain life span for contact controls. Especially the button type, the button will fail after a long time
