Patent ID: 10253933

Abstract:
A light emitting device includes: a base; a laser element disposed on an upper face of the base and adapted to laterally emit a laser beam; a phosphor member disposed on the upper face of the base; a first optical member disposed on the upper face of the base, the first optical member comprising an entry-side lateral face through which the laser beam enters during use and an exit-side lateral face through which the laser beam exits during use, and the first optical member being configured to change a traveling direction of the laser beam such that the laser beam transmitted through the first optical member irradiates an upper face of the phosphor member; and a cap comprising: a light shielding member, and a light transmissive member located over the through hole, the laser element, the phosphor member, and the first optical member. The light shielding member includes a protruded portion extending downward to a position that is lower than an upper end of the first optical member so as to face the exit-side lateral face of the first optical member.
