Antenna Integrated into Optical Element
An antenna is integrated with an optical element, such as a lens, a collimator, a diffuser, a reflector, or some other part that allows at least some light to pass through or reflects light. In some embodiments, the antenna is molded into the optical element. In other embodiments, the antenna is printed on, or attached to, the surface of the optical element. The antenna may be formed from a transparent or a non-transparent conductor, depending on the embodiment.
1 . A lighting apparatus comprising:
a light source;
an optical element situated to allow at least some light from the light source to pass through the optical element;
an antenna integrated into the optical element;
a radio electrically coupled to the antenna to allow radio frequency signals to pass between the antenna and the radio;
wherein the antenna is of a type selected from a group consisting of a loop antenna, an F antenna, and a meander style antenna, and is for communication using a carrier frequency of about 2.4 GHz.
2 . The invention of claim 1 wherein the antenna is molded into the optical element.
3 . The invention of claim 1 wherein the antenna is situated on a surface of the optical element.
4 . The invention of claim 1 wherein the antenna is made of a non-transparent material.
5 . The invention of claim 1 wherein the lighting apparatus is a light bulb.
6 . An apparatus comprising:
an optical element capable of allowing at least some light to pass through the optical element;
an antenna integrated into the optical element;
wherein the antenna is of a type selected from a group consisting of a loop antenna, an F antenna, and a meander style antenna, and is for communication using a carrier frequency of about 2.4 GHz.
7 . The invention of claim 6 wherein the antenna is molded into the optical element.
8 . The invention of claim 6 wherein the antenna is situated on a surface of the optical element.
