Antimicrobial light, such as those in the so-called UVC range (about 222 nm wavelength) have been shown to effectively decontaminate irradiated surfaces against COVID-19 and other harmful depositions on the surfaces, with minimal harmful radiation to humans. Replacing or controlling a smartphone utility light, such as the LED responsive to a “flashlight” function, allows the personal device to be invoked to quickly irradiate surfaces prior to use, such as sitting, eating, opening doors, and the like. ## Claims ### Claim 1 An antimicrobial smartphone flashlight, further comprising: a light source adapted to irradiate a target surface with emitted light having antimicrobial properties; a range detection circuit, the range detection circuit configured for identifying a distance to the target surface; and disinfectant logic, the disinfectant logic for determining, based on a luminescence of the emitted light, a type of the target surface and the distance to the target surface, a duration of light emittance for disinfecting the target surface. ### Claim 2 (depends on 1) The device of claim 1 comprising an integrated antimicrobial light source, the light source powered by a smartphone battery. ### Claim 3 (depends on 2) The device of claim 2 wherein the antimicrobial light source further comprises: a light emitting diode (LED), the LED providing an antimicrobial and safe light emission having wavelengths including at least one of far UVC or antimicrobial visible blue light. ### Claim 4 (depends on 3) The antimicrobial light source of claim 3, wherein: the antimicrobial light source further comprises an additional LED with specific wavelength or LED with capability of emitting various wavelengths. ### Claim 5 (depends on 3) The antimicrobial light source of claim 3 wherein the antimicrobial light source is integrated into a smartphone. ### Claim 6 (depends on 5) The antimicrobial light source of claim 5 further comprising: a retrofit apparatus adapted for attachment onto the smartphone to enable antimicrobial light disinfection. ### Claim 7 An antimicrobial smartphone flashlight system, further comprising: means for invoking smartphone software for performing a 3D scan of a target object, and based on the 3D scan, calculating surface distance, area, shape, and a required antimicrobial light exposure time needed for specified level of disinfection; means for turning an antimicrobial flashlight on for a duration based on the exposure time; and means for disposing the flashlight around a target object to be disinfected. ### Claim 8 (depends on 7) The system of claim 7 comprising a system of quantifying and precisely disinfecting surfaces with an antimicrobial smartphone flashlight. ### Claim 9 An integrated antimicrobial light device, further comprising: an antimicrobial light source for emitting light having antimicrobial properties; a range detection circuit, the range detection circuit configured for identifying a distance to a target surface; and disinfectant logic, the disinfectant logic for determining, based on a luminescence of the emitted light and the distance to the target surface, a duration of light emittance for disinfecting the target surface. ### Claim 10 (depends on 9) The device of claim 9 comprising an electronic device including one of a tablet, iPad, smartwatch, smartphone, 3D scanner, computer, laptop, camera, sensor, robot, instrument, or light emitter. ### Claim 11 (depends on 9) The device of claim 9 wherein the device quantifies and precisely disinfects surfaces with safe, antimicrobial light. ### Claim 12 (depends on 9) The antimicrobial light source of claim 9 wherein the antimicrobial light source is integrated into an electronic device. ### Claim 13 (depends on 9) The antimicrobial light source of claim 9 further comprising: a retrofit apparatus adapted for attachment onto an electronic apparatus to enable antimicrobial light disinfection. ### Claim 14 (depends on 9) The light of claim 9 comprising safe, antimicrobial wavelengths including at least one of far UVC or antimicrobial blue light. ### Claim 15 (depends on 9) The device of claim 9 further comprising a user interface (UI) having a utility lighting selection, a wavelength of the antimicrobial light wavelength emitted selectable via the UI. ### Claim 16 (depends on 9) The device of claim 9 further comprising an object recognition circuit, the disinfectant logic configured to compute the duration based on a type of the object detected by the object recognition circuit. ### Claim 17 (depends on 9) The device of claim 9 further comprising an object recognition circuit, the disinfectant logic responsive to detection of a vulnerable target and deactivating the light source based on the presence of the vulnerable target. ### Claim 18 (depends on 17) The device of claim 17 further comprising: a translucent material in optical communication with the light source, the translucent material formed around a region for disinfectant. ### Claim 19 (depends on 9) The device of claim 9 further comprising: an affixation region, the affixation region configured for attachment in an area for decontamination, wherein device hardware is responsive to a control device for emitting the antimicrobial light.
