Problems solved by technology

[0003] However, compared with LEDs, semiconductor lasers generate a lot of heat when emitting light
In addition, since the energy of the light emitted from the semiconductor laser is also large, the deterioration of the phosphor that generates fluorescence based on the light of the semiconductor laser is also rapid.

Abstract

A laser lighting module (1) includes a base part (21), a laser diode (11) which is a blue laser device, a substrate (12) with which the laser diode (11) is in contact, a ceramic phosphor (13) which reflects light entering from the laser diode to thereby change a direction of the light and is excited by the light to generate yellow fluorescence, and a lens (21) for adjusting luminous intensity distribution of light emitted from the ceramic phosphor(13). The substrate (12) is formed of a material which is thin and has excellent thermal conductivity, and is in surface contact with the laser diode (11) and the base part. In the laser lighting module (1), since the substrate (12) serves as a device heat radiator, it is possible to easily remove the heat generated by the laser diode (11).

Description

technical field [0001] The invention relates to a light source device and a lighting device. Background technique [0002] In recent years, lighting devices using LEDs (Light Emitting Diodes: Light Emitting Diodes) as light sources are used in offices, stores, and the like. On the other hand, a semiconductor laser (LD: Laser Diode) is used as a light source of an optical pickup for an optical drive, a laser printer, a laser pointer, and the like. For example, Japanese Patent Application Laid-Open No. 2011-215531 (Document 1) discloses a projector having a light source that emits laser light. In this projector, a phosphor is arranged on an optical path between a light source and a cross dichroic prism (Cross Dichroic Prism). In the measurement endoscope of Japanese Patent Application Laid-Open No. 2007-205918 (Document 2) or the inner surface measurement device of Japanese Patent Laid-Open No. 2007-33298 (Document 3), the exit surface of the prism on which the excitation li...
