Summary: | PROBLEM TO BE SOLVED: To provide an illumination lamp which efficiently attains an outgoing beam having high uniformity, and to provide a lighting device.SOLUTION: An illumination lamp includes: a laser beam source 21 which emits a laser beam; a plate-like light guide part 30 to which the laser beam emitted from the laser light source 21 enters, the plate-like light guide part 30 which transmits the laser beam between a first surface 33A and a second surface 33B facing each other; a reflection part 32 which is provided at the first surface 33A side and reflects the laser beam to the second surface 33B side; a wavelength conversion part 34 which is provided at the second surface 33B side and converts a wavelength of the laser beam entered from the reflection part 32 side; and a cover 4 which transmits the beam converted by the wavelength conversion part 34.SELECTED DRAWING: Figure 4
【課題】均一性が高い出射光を効率良く得ることができる照明ランプおよび照明装置を提供する。【解決手段】照明ランプは、レーザ光を出射するレーザ光源21と、レーザ光源21から出射されたレーザ光が入射され、互いに対向する第1面33Aと第2面33Bとの間で、レーザ光を伝搬する板状の導光部30と、第1面33A側に設けられ、第2面33B側にレーザ光を反射する反射部32と、第2面33B側に設けられ、反射部32側から入射されたレーザ光の波長を変換する波長変換部34と、波長変換部34で変換された光を透過させるカバー4と、を有することを特徴とする。【選択図】図4 |
