発光モジュール
Document Type and Number:
Japanese Patent JP4151355
Kind Code:
B2
Abstract:
A light emitting module 10 is provided with a semiconductor light emitting device 21 , a semiconductor light receiving device 22 , a mount member 20 on which the semiconductor light emitting device 21 and semiconductor light receiving device 22 are mounted, a lens 32 , and a lens holding member 30 for holding the lens 32 . Part of light emitted by the semiconductor light emitting device 21 is reflected by a reflecting film 32 c provided on a first surface 32 a of the lens 32 to enter the semiconductor light receiving device 22 . Therefore, the semiconductor light receiving device 22 can receive forward light from the semiconductor light emitting device 21 , without using a half mirror.
