Abstract
The device to give LED lighting lamps capacity for coronavirus destruction, allows to give any white light LED luminaire or LED lighting lamp an anti-coronavirus sanitizing capacity through an electronic circuit that drives white lighting LEDs, RGB or fluorescence type in an unconventional way, producing intense and very brief pulses of light within the 400 to 460 nm band, which allows the LED luminaries to produce white light with very narrow pulses of light with 400 to 460 nanometers wavelength controllable using a wall switch. The destruction of coronaviruses is done by weakening the lipid cover of coronaviruses and works for all coronavirus variants.
Claims5
A device to give LED lighting lamps capacity for coronavirus destruction characterized by a voltage overexcitation module that has four terminals, two of which are connected to the electrical power supply through a switch and two others that are connected directly to a fluorescent or RGB white light LED illuminator, where said voltage overexcitation module is in turn constituted by an overexcitation driver and a remote control of sanitization level and where the overexcitation module provides the white light LED illuminators with controlled voltage pulses that exceed by at least 1.5 times the magnitude of the nominal operating voltage of the LED illuminator.
The device to give LED lighting lamps capacity for coronavirus destruction, in accordance with claim number 1, where the voltage overexcitation driver is a relaxation-type circuit, characterized by having a capacitor that is charged through a transistor that constitutes a current source controlled by a second transistor and the corresponding polarization and reference resistances, the latter transistor activates or cuts the current supply to the capacitor based on a signal that in turn controls the activation or cut-off of a field effect transistor that connects to the LEDs of the illuminator in such a way that when this transistor is activated, the entire charge of the capacitor is drained through the LEDs, the field-effect transistor gate is controlled by a comparator with positive feedback that compares the voltage in the capacitor with a reference voltage level set by a voltage divider connected to a fixed voltage so that the discharge of the capacitor through the LEDs is synchronized with the capacitor charge, so that while the capacitor load is being carried out, it is not possible for the capacitor to be discharged and while the capacitor is discharging, the charge of the same capacitor is suspended, all these circuits being powered by a rectifier and a power capacitor, while a sanitization level control circuit regulates the maximum level of the voltage of the discharge pulses by modifying the reference level to the inverter input of the comparator, this level being modifiable by a sequential action of the switch by means of which the voltage overexcitation module is connected to the electrical power supply.
