A negative-pressure cup structure includes a negative-pressure cup body and a light therapy module. The negative-pressure cup body has a rim. The light therapy module is received in the negative-pressure cup body and includes a circuit board and multiple light-emitting diodes (LEDs) mounted on the circuit board and irradiating corresponding to the rim. Therefore, the negative-pressure cup structure further has functions of light therapy and skin care.

The present invention is directed to a tandem-structured bio-organic light emitting diode (bio-OLED) for photodynamic therapy, and to a photodynamic therapy device including the same to convert a red light emitted from the bio-organic light emitting diode into a near-infrared light (NIR) emission, thereby enabling the use of a PBM therapy in a wide wavelength range of 600 to 1,000 nm.

An LED exterior luminaire comprising light-emitting diodes (LEDs) with a circadian-adjustable light output mode for its medical safety comprises at least two switchable LED chip chains I and III, wherein chain I comprising at least one LED chip emitting orange light from a wavelength range of 580 nm to 610 nm and at least one LED chip emitting red light from a wavelength range of 610 nm to 700 nm, chain III comprising at least one blue LED chip overlaid with a luminophore emitting a continuous band spectrum of visible light from a wavelength range of 440 nm to 700 nm and a correlated color temperature CCT of 2200 to 4200 K, wherein chains I and III are each separately connected to a power source via a dimming ballast that regulates the proportion of input current to each chain separately.

Lighting systems, methods, and devices for protecting human circadian neuroendocrine function during night use are described. Suitable lighting conditions can be provided for a working environment while protecting the circadian neuroendocrine systems of those occupying the illuminated workplace during the night. Lighting systems, methods, and devices can provide substantive attenuation of the pathologic circadian disruption in night workers. Lighting systems, methods, and devices can attenuate the specific bands of light implicated in circadian disruption. 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.

The present disclosure presents infant soothing devices which provide timed, color, and intensity controlled light and sound projections to assist in sleep therapy. The devices may be part of a smart nursery which has a number of electronically connected devices which communicate with a central electronic application to gather information and provide operation instructions to the devices. The smart nursery may be connected to a larger network to provide feedback and controllability outside of the nursery.

“DEVICE FOR TREATMENT OF WOUNDS AND MEANS OF USE”, deals with a new configuration applied to a device for wound treatment, for the medical field, where said device has the action of electromagnetic waves on parts of a patient's body, more specifically, a product for the improvement of the treatment of wounds of the body surface as those resulting from severe consequences and difficult healing, which can be used by diabetic or non-diabetic patients.

A method of enhancing penetration of a topical composition of 5-aminolevulinic acid (ALA) into tissue for photodynamic therapy includes topically applying ALA to a treatment area to be treated with photodynamic therapy. The method further includes, after the ALA is applied to the treatment area, covering the treatment area with a low density polyethylene barrier. The treatment area is covered with the low density polyethylene barrier prior to light treatment to minimize transepidermal water loss from the treatment area.

A handheld light therapy device may include a plurality of LEDs selected from a group of colors including red, green, blue, and near infrared, a first and second end, and a light color controller. The first end includes a handle for holding the apparatus and the second end includes the plurality of LEDs. The light color controller receives a light color signal from a user and outputs a polychromatic light corresponding to the light color input signal from at least two of the plurality of LEDs.

The present invention relates to light therapy devices and related methods to treat the female genitalia and areas proximal thereto, including the vaginal cavity and vulvar regions in cisgender females or transgender females who have undergone sex reassignment, in particular for post-surgical indications, vaginal rejuvenation, or other medical conditions suitable for treatment with light therapy. The devices and methods are configured to provide a therapeutic amount of low level light therapy to a patient in need of treatment thereof.
