LED lighting systems, methods, and devices can provide increased intensity at a different portion of the spectrum than conventional LEDs, providing a useable white light even when unfavorable portions of the wavelength are attenuated by a notch filter. LED lighting systems, methods, and devices can switch between a daytime configuration and a night time configuration, wherein the daytime configuration provides unfiltered light and the night time configuration provides filtered light.

A method for treating spermatozoa of an animal includes: irradiating the spermatozoa with light having wavelengths in a range of 390-420 nm at a fluence effective to increase motility of the spermatozoa by 75% or more.

A system includes a laser source coupled to an optical waveguide which has a laser output portion, and a vaginal housing transparent to laser energy which is emitted by the laser source and which exits the laser output portion, wherein the optical waveguide is movable along a path inside the vaginal housing.

Provided is a method of improving a blood flow in a subject's brain, the method including noninvasively sequentially delivering light energy light having a wavelength of about 810 nm to about 870 nm toward blood vessels in an occipital lobe, a temporal lobe, a frontal lobe, and a parietal lobe of the subject along a blood flow starting from one portion of a carotid artery of a subject.

A single loop hardware-based system for producing laser pulses in a microsecond scale operational mode includes a GUI to enable a user to select the operational mode of the system; a laser source for producing one or more laser beam pulses, the laser source being a diode laser pump source module; a DSP which enables and disables a hardware-based FPGA. The FPGA controls the diode pump source module. When a user selects one or more microsecond scale laser sub-pulses on the GUI, the DSP transmits to the FPGA the sub-pulse energy level and the sub-pulse on-time selected by the user on the GUI. A photodetector operatively connected to the hardware-based system measures the power of the laser pulse beam that was transmitted to the photodetector and, in a feedback mode, transmits a feedback signal of that power measurement to the FPGA. The FPGA compares the power of the laser beam measured by the photodetector to the power of the laser beam selected by the user on the GUI. If the power level read by the FPGA is higher than the selected power level, the FGPA decreases the power level to the pumping source module for any subsequent laser pulses; and if the power level read by the FPGA is less than the selected power level, the FGPA increases the power level to the pumping source module for subsequent laser pulses.

A method, system, and apparatus for sterilization, decontamination, and antimicrobial therapeutic treatment, which may include a dispensing device to cover a person, plant, animal, surface, enclosure, room or other structure or area with an antimicrobial solution. Radiation sources may expose the antimicrobial agent to a certain wavelength of radiation. The combination of the solution and the radiation may create a synergistic reaction that causes an effect greater than the radiation or solution separately. The same reaction creates a residual antimicrobial effect. A container, area or passageway including an dispensing device a solution so that a person, plant, animal or object is covered or saturated with an antimicrobial solution. Exposure to a certain wavelength of radiation creates a residual, synergistic reaction resulting in a supercharged antimicrobial agent that exhibits retained antimicrobial effects that exist longer than previously discovered due to the antimicrobial agent being exposed to the radiation together.

A light-emitting module includes a housing, a flexible film, and a protection portion. The housing includes a plurality of light-emitting units arranged in a matrix configuration and at least a switch electrically connected to at least one of the plurality of light-emitting units. The flexible film is detachably coupled to the housing. The protection portion covers the plurality of light-emitting units.

The present invention discloses a method for adjusting the level of galanin in brain, by optic nerve light conduction, comprising the following step: controlling light of different wavelengths, different intensities and different frequencies to illuminate an eye by a light adjustment device, so that galanin receptors in the eye are activated to produce signal, stimulation, and signals transmitted to the hypothalamic visual receiving area via the optic nerve can influence the level of galanin expression in the brain.

Methods and systems for treating a biological fluid with light are disclosed. The methods and systems include determining the light dose being delivered to a biological fluid and adjusting the duration of a treatment or the intensity of light emitted in the event of a detected light source outage.
