The invention relates to a gas discharge lamp for dielectrically impeded discharges, which gas discharge lamp includes a phosphor layer containing a blue phosphor with a host lattice and Nd3+ as the activator, electrodes for a dielectrically impeded discharge and means for igniting and maintaining the discharge. The encapsulation unit includes a first encapsulation material located over the LED chip and a second encapsulation material located around the first encapsulation material. The decode module is coupled to: enable a counting process based on the pre-decoded baseband data to produce a count resultant; and compare the count resultant with a threshold at a data bit interval to produce decoded RFID data. The downward slope of the process tunnel enables gravity to drive the floatingly supported substrates through the successive segments, causing the atomic layer deposition of a film onto the substrates. Wherein the cathode includes a graphene andor graphene oxide. The controller transmits a controller signal to the transceiver after receiving the Hall-effect sensor signal.
