A photo-bio-stimulation device uses near infrared (NIR) laser illumination of the scalp to promote hair growth with a lightweight user wearable device. All the remaining components are mounted on the concave underside of an outer cap shell. Many VCSEL laser device chips are surface mount soldered underneath of a single large flexible printed circuit. These discrete devices direct a diffused, near uniform flood of 678-nanometer monochromatic laser light deep into the hair roots and follicles across the scalps of its users. Petal shapes along a central spine are cut deep into the side edges of the flexible printed circuit to allow it to be conformed and fixed into a hemispherical dome and attached with dozens of plastic snaps inside the outer shell. This connects inside to a rechargeable battery and power controller. A protective clear covering matching the concave underside is attached along the brims.

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.

An adjustable illuminator for photodynamically diagnosing or treating a surface includes a plurality of first panels and at least one second panel. The plurality of first panels have wider widths and the at least one second panel has a narrower width. The narrower width is less than the wider widths. The illuminator further includes a plurality of light sources, each mounted to one of the plurality of first panels or the at least one second panel and configured to irradiate the surface with substantially uniform intensity visible light. The plurality of first panels and the at least one second panel are rotatably connected. The at least one second panel is connected on each side to one of the plurality of first panels. The second panel acts as a “lighted hinge” to reduce or eliminate optical dead spaces between adjacent panels when the illuminator is bent into a certain configuration.

Disclosed are embodiments of a method for affecting thrombi formation on an indwelling catheter. The method involves the step of providing an intravenous catheter. The intravenous catheter includes an inner surface and an outer surface, and the intravenous catheter is located within a blood vessel. A light diffusing element is inserted into the intravenous catheter. Light is emitted from the light diffusing element such that the light irradiates the intravenous catheter. The light emitted from the light diffusing element is configured to promote or hinder thrombi formation on the inner surface or outer surface of the intravenous catheter. Also disclosed are an illumination system for affecting thrombi formation on an intravenous catheter as well as an indwelling intravenous catheter system.

The present disclosure provides systems, methods and apparatuses for inducing a desired biological response in an organism through the use of one or more repetitive signals from one or a series of LED lights designed to emit the signal with multiple pulsed components. Each component of the signal contains a one or more light color spectrum or wavelength that is within 50 nm of the peak absorption of a photon receptor of the organism corresponding to the desired biological response. Each component has a repetitive ON duration with an OFF duration and an intensity where the relationship between the ON duration and OFF duration of the first component and the second component induces the desired response in the organism through the stimulation or excitation of a molecule associated with a photoreceptor and the reset of the molecule.
