NK8035A Pre-wired Lighthouse Beacon Kit
Product & installation overview:
The NK8035A is designed to generate slowly increasing & decreasing brightness
for
the LED connected
to its outputs (solder points
3 & 4) when power is applied to the inputs (points
1 & 2).
The lighting effect is timed to accurately represent the slowly rotating beacon in a
lighthouse.
Utilizing the industry’s smallest
microcontroller and associated voltage control circuitry, the total module
with LED
consumes less than
20 ma. This
makes the NK8035A well
suited for low power applications such as battery operation but can easily be
powered by any well-filtered and regulated DC power source with an output of
6-18VDC. The very small overall size of this module will allow it to be easily
placed in and around any structure, even in Z-scale.
Connecting the NK8035A:
Installing
the NK8035A is very straightforward. Because the
module has circuitry on both sides, care must be taken to be sure that the
components or wire solder points will not make contact with any metal object which could cause a short
circuit.
This
kit is pre-wired with input power wires already connected. The red wire is for
connection to +DC and the black wire is for connection to –DC (ground). These
wires are pre-tinned for easy soldering
to your power source. Figure 1 below shows a close-up of the circuit and
wiring connections. Point 3 & 4 are the outputs that connect to the attached
LED. All wires are multi-stranded so they are very flexible allowing for easy
routing in the model.
Important note:
A low-wattage
iron with a pointed tip should be used for connection of wires. Too much heat or
solder can easily damage the wires.
Figure 1
The LED is a
Ngineering N1022C high intensity Incandescent LED. It is quite bright and is
constructed in a 2 X 3mm ceramic housing. Although the main source of light is
out of its face (surface with the orange oval) it produces sufficient side-shine
that it can be mounted facing up and
still project sufficient light from all 4 sides to illuminate the beacon area of
a lighthouse model.
We recommend
mounting the LEDs from the back by attaching adhesive to the wires near
the back of the LEDs so adhesive is not placed directly on the LED. It
is also recommended that whatever adhesive is used that it does not
contain high aggressive solvents that could attack the insulation on the
wires. Walthers Goo is an example of an “aggressive” solvent type
adhesive. Elmers white Glue, CA (superglue) and 2-part epoxies are very
safe for this type of mounting and will not damage wires or surfaces of
your model in most cases.
If the LED
is to be mounted slightly above a flat surface, we recommend cutting a
narrow slot from the edge of the surface to slide the wires into
position where the LED is to be located. Then gluing the wires in
position will be very easy and hold the LED in place while the adhesive
dries.
This
completes hookup of our NK8035 Lighthouse module. We hope the added
realism it provides enhances your enjoyment of the hobby.
