Abstract
A linear light emitting diode (LED) light including electrical-to-optical converters (EOs) on circuit boards in end housings to couple photons into ends of an acrylic rod. Photons from the electrical-to-optical converters radiate from the acrylic rod to light the space around the linear LED light.
Claims18
A light comprising;
- an acrylic rod having a first end and a second end;
- a first circuit board including one or more electrical-to-optical converters to generate photons;
- a first end housing having a first opening through which the first end of the acrylic rod is inserted, the first end housing to house the first circuit board and align the one or more electrical-to-optical converters of the first circuit board with the first opening and the first end of the acrylic rod;
- and
- a first reflector coupled to the first circuit board around the one or more electrical-to-optical converters at a first end, a second end of the first reflector aligned with the first opening and receiving the first end of the acrylic rod, the first reflector to reflect photons into the acrylic rod.

A light comprising:
- an acrylic rod having a first end and a second end;
- a first circuit board including one or more electrical-to-optical converters to generate photons;
- first end housing having a first opening through which the first end of the acrylic rod is inserted, the first end housing to house the first circuit board and align the one or more electrical-to-optical converters of the first circuit board with the first opening and the first end of the acrylic rod;
- an electrical-to-optical controller coupled to the first circuit board to control the one or more electrical-to-optical converters;
- an on/off switch to switch the generation of photons by the one or more electrical-to-optical converters on and off;
- and
- an intensity selection switch to vary the brightness of the generated light.

A light comprising:
- an acrylic rod having a first end and a second end;
- a first circuit board including one or more electrical-to-optical converters to generate photons;
- a first end housing having a first opening through which the first end of the acrylic rod is inserted, the first end housing to house the first circuit board and align the one or more electrical-to-optical converters of the first circuit board with the first opening and the first end of the acrylic rod;
- and
- a transformer to transform AC power to a safe efficient power to power the one or more electrical-to-optical converters of the first circuit board in an efficient manner.
2 more elements
A method of lighting without a light bulb, the method comprising:
- generating first photons of a desired color;
- coupling the first photons into a first end of an acrylic rod;
- radiating the first photons out of the acrylic rod as light;
- and
- uniformly varying the mixture of the first photons generated and coupled into the acrylic rod to vary the intensity of the light.
