• Low costs. This is true for most
lighting applications.
A remote-controlled lamp often
includes a microcontroller, either as
a discrete component or integrated
in another IC. Unless a complex
communication protocol is adopted
with a complex stack (e.g., ZigBee®),
a basic microcontroller is typically
sufficient. The microcontroller’s
duties will typically include decoding
of the communication protocol,
generation of dimming signals for
the LED driver, reading faults, and
controlling the lighting effects of the
lamp (e.g., theater dimming).
For wireless communication in
lighting applications, Maxim offers
the MAX1473 receiver and the
MAX1472 transmitter. These products
allow communication in the 300MHz
to 450MHz free bands, over a range
of 30m to 50m in an indoor environ-
ment. The MAXQ610 microcontroller
offers all the required features at a
low cost.
For PLC, Maxim’s solution includes
the MAX2991 analog front-end (AFE)
and the MAX2990 baseband
processor. These devices form a
powerline transmitter/receiver
chipset that is capable of transmit-
ting data over distances up to 10km
and at data rates up to 100kbps.
This range makes the parts ideal
for street-lighting applications.
A microcontroller with PWM outputs
to control the PWM dimming input of
the LED driver is integrated into the
MAX2990. This feature eliminates the
need for another circuit to generate
this signal.
