A light-emitting section () and a transparent member () which is arranged on a side of a surface (SUF) of the light-emitting section () and exhibits transparency with respect to laser light (L) are provided, and the transparent member () includes a plurality of scattering microregions (MP) which isotropically scatter the laser light (L) passing therethrough and increase a light-emission spot size of the laser light (L).

Light-emitting element, light-emitting device, and method for product light-emitting element

The light-emitting section contains a fluorescent substance which is a YAG:Ce fluorescent substance. An average particle size of the fluorescent substance is 1&#xb7;m or larger and 50&#xb7;m or smaller, and a sealing material for sealing the fluorescent substance has a density of 2.0 g/cmor higher and 7.0 g/cmor lower.

Wavelength converting member, light-emitting device, illuminating device, vehicle headlight, and method for producing wavelength converting member

A headlamp () includes a semiconductor laser (); a light-emitting element () that emits light in response to laser light emitted from the semiconductor laser (); a heat-conducting member () that receives heat generated by the light-emitting element () through a light-emitting-element facing surface (); and a gap layer () that is disposed between the light-emitting element () and the light-emitting-element facing surface () and that conducts the heat generated by the light-emitting element () to the light-emitting-element facing surface (). The gap layer () contains at least an inorganic amorphous material.

Light-emitting apparatus, illumination system, vehicle headlamp, projector, and method for manufacturing light-emitting apparatus

A positional deviation detection unit () includes a detection portion () that detects a relative positional relationship between a laser element (), a condensing lens (), and a light emitting portion (), and a determination portion () that compares a detection result from the detection portion () with a reference relative positional relationship which is used as a reference for the relative positional relationship, so as to determine whether or not there is a deviation of the relative positional relationship between the laser element (), the condensing lens (), and the light emitting portion () when the detection portion () performs the detection, from the reference relative positional relationship.
