Energy harvesting wireless light switch AFIS-2004
Safety instructions
1. Application field
Batteryless and wireless RF light switch for the direct communication with a LED bulb.
2. Product description
2.1 Light Switch
The light switch includes a generator which converts the mechanical energy of the switch into electrical energy. The
energy is used for the RF electronics and the data is transmitted without batteries and wires via 2.4 GHz to a receiver
integrated into the LED bulb.
2.2 Receiver
The receiver chip NXP JN51xx is integrated into the LED bulb. The chip receives the RF signal from the light switch
and forwards the information for switching the bulbs on and off.
3 Implementation
For the implementation, a E27 socket powered with 230V/AC is necesseary. Functions: On / Off / Dimming

5. Declaration of Conformity
Radiofrequency radiation exposure Information:
The radiated output power of the device is far below the FCC radio frequency exposure limits. Nevertheless, the
device shall be used in such a manner that the potential for human contact during normal operation is minimized.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
