The invention relates to a body irradiating device, in particular for irradiating a body of a person or a part of a body of a person, in particular with cosmetically and hygienically useful radiation, comprising a radiation source with a base and at least one first LED chip which can emit a first radiation spectrum with a first radiation peak and at least one second LED chip which can emit a second radiation spectrum with a second radiation peak differing from the first radiation peak. A body irradiating device allowing the radiation spectrum of more than one LED chip to be combined and uniformly supplied to the human body is achieved in that the first LED chip and the second LED chip are arranged below a common lens in an LED package and can be controlled separately.

A light based therapy helmet has a circuit board layer which is equipped with multiple lighting dots. Each of the multiple lighting dots respectively is a first, a second or a third light-emitting unit. The first, the second and the third light-emitting units respectively emit a light of a first, a second and a third light band which respectively include a wavelength of 660 nm, 940 nm and 1600 nm. A lower helmet body is provided with an accommodation space configured for a user's head to be accommodated directly. An upper helmet body is provided with an accommodation space that fits the circuit board layer. When the lower helmet body, the circuit board layer, and the upper helmet body fit together, the circuit board layer is fixed between the upper helmet body and the lower helmet body. A controller controls the on/off and the brightness of the multiple lighting dots.

A personal therapy compartment includes a base of size to receive a human patient. The compartment includes a bed in the base said bed being made of a light transmissive material. An array of lights mounted is below the bed to transmit light onto a body supported on the bed. A control panel controls at least the wavelength, intensity and pulsation of the light.

Methods of treating skin disorders are disclosed. The methods involve impinging light having a first peak wavelength on the tissue at a first radiant flux, wherein the first peak wavelength and the first radiant flux is selected to provide an anti-inflammatory effect, and impinging light having a second peak wavelength on the tissue at a second radiant flux, wherein the second peak wavelength and the second radiant flux are selected to either stimulate enzymatic generation of nitric oxide to increase endogenous stores of nitric oxide or release nitric oxide from the endogenous stores are disclosed. Representative skin disorders include pruritus, psoriasis, acne, rosacea, and eczema, and the skin can include the scalp. The methods can reduce stinging and/or itching associated with the skin disorder. The anti-inflammatory wavelengths can be in the range of between about 650 and about 680 nm.
