Abstract
Lighting apparatuses and LED modules capable of both illumination and data transmission are disclosed. An exemplifying lighting apparatus has a LED module and a modulator. The LED module comprises a plurality of LED cells connected as a LED chain having two conductive pads. The light emitted from the LED module is visible. The modulator provides driving current to the LED module to transmit data.
Claims20
A lighting apparatus capable of simultaneously providing illumination and data transmission to a receiver, comprising:
- an LED module capable of emitting visible light, comprising a plurality of LED cells connected as an LED chain having two conductive pads;
- a modulator providing driving current to the LED module to transmit data through the LED module.
An LED cell module, comprising:
- a substrate;
- LED cells monolithically formed on the substrate, wherein a first group of the LED cells is connected as a first LED chain, driven for illumination, and a second group of the LED cells is connected as a second LED chain for data transmission;
- a first pair of conductive pads connected to the first LED chain and a second pair of conductive pads different from the first conductive pads, connected to the second LED chain.
