Claims19
A semiconductor laser device including:
- a semiconductor laser chip;
- and
- a molded lens that encapsulates the semiconductor laser chip,
- wherein said molded lens is made of a resin compound, said resin compound comprising
- two or more materials of different refractive indexes providing light diffusion capability, and
- wherein the laser light emitted from the semiconductor laser chip is diffused through said molded lens.
A semiconductor laser device including a semiconductor laser chip encapsulated within molded lens, said molded lens made of resin having a light diffusion capability, wherein the semiconductor laser chip includes a plurality of light emitting portions.
A semiconductor laser device including a semiconductor laser chip encapsulated within molded lens, said molded lens made of resin having a light diffusion capability, wherein the semiconductor laser chip includes at least one light emitting portion having a width of about 7 μm or more.
A semiconductor laser device including a semiconductor laser chip encapsulated within molded lens, said molded lens made of resin having a light diffusion capability, and further including at least one additional semiconductor laser chip.
