Abstract: A light source device includes a connector, a light source, a lever member, and a detector. The connector allows the light guide member to be detachably connected thereto. The light source emits light to be incident on the light guide member connected to the connector. The lever member is displaced depending on presence or absence of the connection of the light guide member to the connector. The detector detects the displacement of the lever member and outputs a detection result.

Abstract: A light source device includes: an excitation light source that emits primary light; a first lens that condenses the primary light; a wavelength converting member that emits secondary light including the primary light and wavelength converted light; a sensor that detects an anomaly in the wavelength converting member; and a second lens that causes light which travels back toward the excitation light source to be incident on the sensor. The sensor detects the light via the second lens. The first lens includes (i) a first face through which the primary light enters, and (ii) a second face opposite the first face from which the primary light that has entered from the first face and transmitted through an inside of the first lens exits. The third face of the second lens has a curvature different from a curvature of the first face and the second face of the first lens.

CPC classification number: F21V23/0457 , F21V9/40
Abstract: The light source device includes at least one excitation light source which emits primary light, a light conversion member which emits secondary light that contains the primary light and wavelength-converted light obtained by converting a wavelength of at least part of the primary light, a sensor which detects the primary light and the wavelength-converted light, and a controller which obtains a first signal which is a signal indicating the detected primary light and a second signal indicating the wavelength-converted light detected by the sensor. The controller determines an operation safety parameter based on a ratio of an output value of the first signal to an output value of the second signal, and controls the at least one excitation light source based on the operation safety parameter with respect to a predetermined threshold or an amount of change of the operation safety parameter from that during normal operation.

Abstract: A light source device, includes: a plurality of excitation light sources that emit primary light; an optical member that condenses the primary light; a fluorescent unit that emits secondary light including the primary light and wavelength converted light which is at least some of the primary light on which wavelength conversion is performed; and a sensor that detects an anomaly in the fluorescent unit. In addition, when seen along an optical axis of the primary light emitted by the plurality of excitation light sources, the sensor circumscribes, among the plurality of excitation light sources, a first excitation light source and a second excitation light source different from the first excitation light source, and is disposed inside an imaginary circle having, as a diameter, a line segment connecting the first excitation light source and the second excitation light source.

Abstract: A light-emitting device that emits output light, is a light-emitting device that includes: a light-emitting element that emits a primary light; and a wavelength converter that converts at least a portion of the primary light into a secondary light. The output light includes at least a portion of the secondary light. The output light has a light intensity greater than or equal to a predetermined value throughout an entire wavelength range of from 750 nm to 900 nm, inclusive. A ratio of a light intensity of the output light at 900 nm to a light intensity of the output light at 750 nm is greater than or equal to 0.2 and less than 3.0. The output light has a spectral luminosity of at least 0.1 lm/W and at most 10 lm/W.
