Lens and light-emitting device including the lens
First Claim
1. A lens defining a central axis, said lens comprising:
- a bottom surface;
a first reflecting surface obliquely angled with respect to the central axis and extending from said bottom surface in a direction away from the central axis;
a second reflecting surface obliquely angled with respect to the central axis; and
a refracting surface obliquely angled with respect to the central axis and extending from said second reflecting surface in a direction toward the central axis;
wherein light entering said lens through said bottom surface and directly incident on said first reflecting surface is reflected from said first reflecting surface to said second reflecting surface, is subsequently reflected from said second reflecting surface to said refracting surface, and is then refracted from said refracting surface to exit said lens and to form a first refracted light beam; and
wherein light entering said lens through said bottom surface and directly incident on said second reflecting surface is reflected from said second reflecting surface to said refracting surface, and is then refracted from said refracting surface to exit said lens to form a second refracted light beam.

Abstract
A light-emitting device includes a light-emitting component and a lens. The lens includes a bottom surface, a first reflecting surface, a second reflecting surface, and a refracting surface such that light entering the lens through the bottom surface and directly incident on the first reflecting surface is reflected from the first reflecting surface to the second reflecting surface, is subsequently reflected from the second reflecting surface to the refracting surface, and is then refracted from the refracting surface to exit the lens, and that light entering the lens through the bottom surface and directly incident on the second reflecting surface is reflected from the second reflecting surface to the refracting surface, and is then refracted from the refracting surface to exit the lens.

12. An light-emitting device comprising:
-
a package base;
a light-emitting member mounted on said package base; and
a lens mounted on said package base, covering said light-emitting member, and defining a central axis, said lens including;
a bottom surface, a first reflecting surface obliquely angled with respect to the central axis and extending from said bottom surface in a direction away from the central axis, a second reflecting surface obliquely angled with respect to the central axis, and a refracting surface obliquely angled with respect to the central axis and extending from said second reflecting surface in a direction toward the central axis;
wherein, light emitted by said light-emitting component, entering said lens through said bottom surface, and directly incident on said first reflecting surface is reflected from said first reflecting surface to said second reflecting surface, is subsequently reflected from said second reflecting surface to said refracting surface, and is then refracted from said refracting surface to exit said lens to form a first refracted light beam; and
wherein light emitted by said light-emitting component, entering said lens through said bottom surface, and directly incident on said second reflecting surface is reflected from said second reflecting surface to said refracting surface, and is then refracted from said refracting surface to exit said lens to form a second refracted light beam. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
