This procedure in general surgery, in case of sudden power failure, the most tight is the shadowless lamp. All kinds of UPSs sold on the market, that is, uninterruptible power supply, are difficult to use for shadowless lamps because of their voltage capacity and other reasons. I use some of the components of the waste equipment, designed and converted into a shadowless lamp dedicated UPS, the trial for seven holes shadowless lamp for two hours and 30 minutes (if equipped with large-capacity battery, the use of time can be extended), power easy to use , Operation and maintenance is simple, see power schematic. The UPS mainly by the controller and battery two parts. Storage battery with 12V40AH car battery two, installation
