The invention relates to a body irradiation device for use of directional actinic radiation on a living organism, in particular a human being, which comprises at least one irradiation module, and wherein the at least one irradiation module comprises: at least two LED radiation sources which generate the actinic radiation and are arranged on a common carrier; a plate which spans the at least two LED radiation sources, wherein the plate is spaced apart from the carrier; at least two planoconvex optical lenses which are integrally bonded to the plate such that the flat surfaces of the lenses face the carrier, and wherein each lens is configured and arranged in such a way as to at least substantially collimate or direct radiation emitted by one of the LED radiation sources.

The invention relates to a skin tanning chamber, the improvement comprising at least one light emitting diode emitting a UVA light, such as a UVA LED that emits essentially only UVA. Additionally, multiple LEDs of varying types with various characteristic wavelengths are controlled independently to produce an arbitrary light pattern in an arbitrary sequence over time. The chamber can be rigid or flexible. It can be a bed, booth or incorporated into a flexible form, such as a garment or cloth. In one embodiment, the chamber further comprises at least one LED emitting a UVC light, whereby the UVC light sanitizes the chamber surface. Preferably the LED emitting the UVA light is under independent control from the LED emitting UVC light.

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.

Equipment including a lamp for producing UV light in the range 300-314 nm wavelength having spectral power in the range 302-307 nm wavelength across a 5 nm bandwidth of 40% of overall spectral power and spectral power in the range 307-312 nm of 40% of overall spectral power with a reflector of 90% reflectance in the range 300-314 nm wavelength. A key operated arming switch is series connected to a timer switch.
