Abstract: A projection system includes: a projection device that includes a laser scanner and projects one or more drawings individually onto work spots in a work site; and an adjustment unit configured to adjust at least one of (i) a quantity of the one or more drawings to be simultaneously projected by the projection device or (ii) a setting parameter regarding a mode of projection performed by the projection device.

Abstract: A projection method, which is executed by a projection device, for projecting drawing data for a building onto a projection plane of the building under construction includes: measuring a distance from each of three or more points which are not aligned in a straight line and are on either of two non-parallel straight lines on the projection plane to the projection device using a distance meter included in the projection device; and projecting the drawing data onto a projection position on the projection plane which is determined based on the distance measured and the angle of the distance meter at the time at which the distance is measured.

Abstract: A projection system includes a projection device that projects drawings individually onto a plurality of work spots in a work site. The projection device includes a driver that changes an orientation of the projection device. When drawings are individually projected onto a first work spot and a second work spot in a stated sequence, and the second work spot is outside a projection angle that is projectable by the projection device, the driver changes the orientation of the projection device to include the second work spot within the projection angle after work at the first work spot is finished. The first work spot and the second work spot are included in the plurality of work spots.

Abstract: An illuminating device according to the present disclosure is of a reflective type and uses a laser beam. The illuminating device includes: a laser element that emits a laser beam; an optical fiber that transmits the laser beam emitted by the laser element; a phosphor layer that converts a wavelength of light incident on one of surfaces and emits the light through the one of the surfaces; and an optical component that causes reflected light of the laser beam transmitted through the optical fiber to be incident on the one of the surfaces of the phosphor layer. With the illuminating device, an intensity distribution of the light incident on the one of the surfaces of the phosphor layer is sparse at a central region.

Abstract: A lighting device is provided which includes: a wavelength converter that emits, from laser light, light having a wavelength different from a wavelength of the laser light; and a reflector surrounding the wavelength converter and including a surface of revolution that reflects the light emitted from the wavelength converter. The reflector includes, in the surface of revolution, a through-hole through which the laser light passes.
