Abstract: A flexible light therapy device, a bandage and a plaster for providing a therapeutic effect to a treatment target area (226) of a living being are provided. The flexible light therapy device comprises a light source (214) for emitting light (220), a light transmitting element (212) and a heat management means (210). The light transmitting element (212) is of a flexible light transmitting material and is optically coupled to the light source (214). The light transmitting element (212) comprises a light exit window (222) to emit the light (220) towards the treatment target area (226). The heat management means (210) is thermally coupled to the treatment target area (226) and distributes heat and controls the distribution of heat across the treatment target area (226). Part of the distributed heat may originate from the light source (214).

Abstract: A light-emitting device includes a plurality of light-emitting elements or light sources and a flexible pad for positioning and conforming the light-emitting device to a portion of a body of a user. The flexible pad includes a three-dimensional structure having a plurality of protrusions for contacting a skin of the portion of the body when the light-emitting device is applied to the portion of the body by the flexible pad. Further, the three-dimensional structure includes a plurality of recesses for creating a clearance between the skin and the flexible pad when the light-emitting device is applied to the portion of the body, and a plurality of apertures for engaging with the plurality of light-emitting elements. Each protrusion includes an extended part and a withdrawn part, where the extended part is further extended than the withdrawn part, and the extended part is configured to contact the skin.

Abstract: A relative flux sensor (122) and a method of characterizing characteristics of light emitters are provided. The relative flux sensor (122) comprises a color point sensor (108) and a sensor color (118). The color point sensor (108) measures a color point in a color space of light emitted by a light source (101) comprising a first light emitter (102) for emitting light of a first color and a second light emitter (114) for emitting light of a second color being different from the first color. The light source (101) is arranged for emitting light of a controllable color, being a mix of light of the first color and light of the second color.
