A lighting device is described that includes a voltage source, a substrate, a wiring, a first light emitting diode (LED) and a second LED, a first electrical conductive element (ECE) and a second ECE, and a transparent, conductive sheet material. The wiring is formed on the substrate, and is connected to the voltage source. The first LED and the second LED are formed on the wiring. The first ECE and the second ECE are formed on the wiring. The sheet material is laminated onto the first and second LEDs and the first and second ECEs. The first and second LEDs are electrically connected in parallel and have opposite polarities. A sheet resistance exists between the first ECE and the first LED and between the second ECE and the second LED.
