The present invention relates to a dermatological treatment apparatus. Such dermatological treatments include but are not limited to hair removal, treatment of acne and lesions and also skin rejuvenation. The apparatus comprises a housing; a light emitting source provided in the housing arranged to emit light energy along an energy pathway to external of the device; and a filter arrangement positioned in the energy pathway having at least a first and a second light energy filtering portion together combining to span across the energy pathway for filtering the light energy passing to external of the device.

The present disclosure is directed to a phototherapeutic apparatus for focused UVB radiation and vitamin D synthesis and associated systems methods. In one embodiment a phototherapeutic apparatus can include a housing at least partially defining an irradiation zone, and an ultraviolet (UV) radiation source carried by the housing. The irradiation zone can be configured to accommodate at least a portion of a human patient. The phototherapeutic apparatus can further include a filter between the UV radiation source and the irradiation zone. The filter can be configured to at least substantially remove UV radiation outside of a predetermined spectrum centered at about 297 nm and having a bandwidth of at most 10 nm.

Certain exemplary embodiments of the present disclosure can provide an apparatus and method for generating at least one radiation can be provided. The exemplary apparatus and/or method can selectively kill and/or affect at least one bacteria. For example, a radiation source first arrangement can be provided which is configured to generate at least one radiation having one or more wavelengths provided in a range of about 190 nanometers (nm) to about 230 nm, and at least one second arrangement can be provided which is configured to prevent the at least one radiation from having any wavelength that is outside of the range can be provided.

The present invention is directed to a system and method for photoeradication of microorganisms from a target. The target is irradiated with pulsed purple or blue light in which (a) the light pulses have a peak irradiance and a pulse duration sufficient to optically excite a photoactive molecule capable of photoeradication of the microorganisms and (b) the light pulses are separated by an off time sufficient to allow the photoactive molecule to return to a ground state creating an oxidation reaction that produces free radicals which destroy a cellular structure of the microorganisms and thereby photoeradicate all or a portion of the microorganisms. The photoactive molecule may comprise either an endogenous molecule present in the microorganisms or an exogenous molecule applied to the target.

The present invention provides a composite intelligent biological phototherapy device including a base structure, a plurality of white light fluorescent tubes arranged side by side on the base structure, a plurality of LEDs disposed between the white light fluorescent tubes, a housing having an opening and configured to accommodate the base structure and the white light fluorescent tubes and the LEDs thereon, a light-transmittable plate disposed on the housing corresponding to the opening, and an control module configured to respectively control the white light fluorescent tubes and the LEDs. The base structure includes a plurality of sections, and each of the sections has a first surface facing the light-transmittable plate. The white light fluorescent tubes and the LEDs are provided on the first surfaces, and the sections are bent relative to each other so an angle between the first surfaces of adjacent sections is less than 180 degrees.

A light therapy apparatus is provided for delivering ocular light to a subject to treat disorders that are responsive to ocular light therapy, including a power supply and a hand-held light output device. The light output device includes a plurality of light sources powered by the power supply. A method of light therapy is provided, wherein ocular light is administered to a subject to treat disorders that are responsive to ocular light therapy. The method includes delivering the light to the eyes of a subject by a hand-held light source operated by a power supply.
