Light guide bar and light emitting device

摘要

A light guide bar includes a light guide member and a light scattering member. The light guide member defines a cutout. The light guide member includes a first end surface, a second end surface, and a circumferential surface interconnected between the first end surface and the second end surface. The cutout is defined in the circumferential surface and passes through the first end surface and the second end surface. The light scattering member is received in the cutout and scatters light back to the light guide member. The light scattering member and the light guide member cooperatively form a complete cylinder, and a thickness of the light scattering member is less than a radius of the light guide member.

主权项

1. A light guide bar comprising:
a light guide member being substantially a cylinder with a cutout, the light guide member comprising a first end surface, a second end surface and a circumferential surface connecting the first end surface and the second end surface, the cutout defined in the circumferential surface along an axial direction of the light guide member and exposed at the first end surface and the second end surface; and a light scattering member received in the cutout for scattering light back to the light guide member, the light scattering member and the light guide member cooperatively forming a complete cylinder, and the largest radial thickness of the light scattering member being less than the radius of the light guide member.
