Abstract: An illumination device includes a light source, a transmission part and a lighting appliance. The light source is configured to emit a laser light. The transmission part is configured to transmit the laser light emitted from the light source through an optical fiber. The lighting appliance is configured to convert a wavelength of the laser light transmitted through the transmission part and emit an illumination light. The transmission part includes a guide part having a rail-shape and extending along a transmission direction of the laser light. The lighting appliance is further configured to be mounted in an arbitrary position of the guide part.

Abstract: An optical fiber holding structure includes a light-transmitting tube configured to cover a surface-light-emitting optical fiber and a fixture configured to fix the tube to a building material. The tube is made of a material having such rigidity that the tube is not bent even when the tube is horizontally fixed by the fixture. The tube has a notch through which the optical fiber is introduced into the tube. The fixture includes an engaging portion, a mounting portion and a leg portion. The engaging portion is inserted into the tube through the notch to engage with an inner circumference of the tube. The mounting portion is mounted to the building material. The leg portion is configured to interconnect the engaging portion and the mounting portion with a predetermined gap left therebetween.

Abstract: An illumination device includes a light source unit and a light guide plate configured to guide light coming from the light source unit. The light guide plate includes an incidence surface, main emission surfaces from which the light incident on the incidence surface is emitted, and an end emission surface which is opposed to the incidence surface and from which the light is emitted. At least one of the main emission surfaces has a stepped surface which is formed such that the thickness of the light guide plate becomes thinner at a side of the end emission surface than at a side of the incidence surface. The stepped surface is configured to reflect the light in a direction opposite to a light guide direction extending from the incidence surface toward the end emission surface and inclined with respect to the light guide direction.

Abstract: An illumination device includes a light source configured to emit laser light; and a wavelength conversion part configured to convert a wavelength of the laser light emitted from the light source and to irradiate illumination light. The wavelength conversion part includes a conversion region provided with a phosphor which converts the wavelength of the laser light and emits the wavelength-converted laser light, and a non-conversion region not provided with the phosphor and configured to transmit the laser light irradiated from the light source. The non-conversion region is formed in a pinhole shape with respect to the conversion region.

Abstract: An illumination device includes a light source configured to emit laser light, a transmission part configured to transmit the laser light emitted from the light source, and a lighting appliance configured to convert a wavelength of the laser light transmitted through the transmission part and to emit illumination light. The transmission part includes a rail-shaped guide part extending in a linear shape along a transmission direction of the laser light. The lighting appliance is configured to be mounted in an arbitrary position of the guide part.
