Beschreibung
Zusammenfassung:	The utility model provides a novel technology capable of reducing the possibility that laser with high energy density is not scattered and leaked to the outside. The light-emitting module includes: alight-emitting element that emits laser light; a wavelength conversion member that emits converted light obtained by wavelength-converting the laser light; and a detection unit (26) that is fixed to the wavelength conversion member and detects the amount of displacement of the wavelength conversion member. The detection unit (26) includes a piezoelectric material that outputs an electrical signalthat varies in accordance with the amount of displacement of the wavelength conversion member. 本实用新型提供一种可降低具有较高能量密度的激光不被散射地向外部漏出的可能性的新技术。发光模块包括：发光元件，其发出激光；波长转换构件，其发出将激光进行波长转换后得到的转换光；以及检测部(26)，其被固定于波长转换构件，并对该波长转换构件的位移量进行检测。检测部(26)包含压电材料，该压电材料输出根据波长转换构件的位移量而变化的电信号。
