LIGHTING DEVICE AND LIGHT CONTROL COMPONENT THEREOF
First Claim
1. A lighting device comprising:
- a base;
a light emitting component disposed on said base and operable to generate light when supplied with electricity; and
a light control component disposed on said base, and cooperating with said base to enclose said light emitting component, said light control component including a light transmissive body made of a material having a predetermined refractive index, said light transmissive body having;
a datum point,a main axis passing through said datum point,a light incident surface that is disposed to receive light from said light emitting component and that is axis symmetrical relative to said main axis, said light incident surface including a plurality of annular incident surface portions that form a Fresnel lens configuration and that are concentric with respect to said main axis, anda light exit surface that is spaced apart from said light incident surface and that is axis symmetrical relative to said main axis.

Abstract
A lighting device includes a base, a light emitting component operable to generate light, and a light control component cooperating with the base to enclose the light emitting component. The light control component includes a light transmissive body that has a datum point, a main axis passing through the datum point, a light incident surface that is axis symmetrical relative to the main axis, and a light exit surface that is axis symmetrical relative to the main axis. The light incident surface includes a plurality of annular incident surface portions that form a Fresnel lens configuration and that are concentric with respect to the main axis.
