This simulator replicates the older-style signal and hazard warning flashers that used incandescent (filament) lamps to generate light. Typical flash rate of 3/4 second with a increasing and decreasing brightness curve to duplicate that of filament type lamps. Three outputs will each drive up to one pair (wired in  series) of red and/or yellow LEDs Outputs flash sequentially so the module could also drive a very short series of "chase" lights.

This simulator provides a single repeating burst, increasing and decreasing in intensity for a single yellow 20ma LED. While designed to mimic a typical roof warning beacon, it also simulates the effect of most early-era bulb-type roadside warning flashers (detour, road work, pedestrian crossing, hospital zone, etc.).

Early-era Alternating Flasher Simulator

This module reproduces alternating flashes (with increasing and decreasing brightness curves) as seen in the older early-era incandescent lamp driven traffic signals alternating between red and yellow (yield and stop) at intersections, or 2 alternating yellows, such as a school zone. Will drive two pairs of series-wired red or yellow (or mixed) LEDs without additional external circuitry.

This module is designed to reproduce a highly realistic simulation of a rotating beacon by sequencing 3 yellow LEDs (sold separately) that are positioned to produce the effect. See LED Construction in the More Info table to the right for complete information. The timing of the rotational effect replicates that of rotating beacons used occasionally on street or highway signs to draw attention.

Do you need a special lighting effect that that no one produces or have a unique prototype requirement? We may be able to help. The N8050 will support 1 LED output, the N8051, 2 LED outputs, and the N8052 will support 3 LED outputs. For an additional programming charge (quoted separately), we will program the appropriate simulator to create your effect. Just email or call us with your requirements. We will review them, determine if they are within the capabilities of our simulator, and if so, respond with our quotation. Delivery can be within 2 weeks and our quote will be reasonable.

Catenary Spark Simulator

We have all watched electric locomotives, traction vehicles or trolleys as they move along the rails and have seen the sparks created by the pickup as it travels along the overhead (catenary) wires. This visual effect also very closely resembles the sparking seen with shorting power cables such as wires between power poles. The tiny size of our Nano white LEDs are perfect for this application, and if strategically placed will greatly enhance a scene of a roadside repair crew.

Arc & Gas Welding Simulators

Finally, welding simulation that looks just like the real thing! A bit of shameless back-patting, but we believe it is warranted. These simulators are configured for connection of two LEDs to accurately reproduce the varying intensity, intermittence and slight color changes just like real welders. Our Nano LEDs are perfect for reproducing these effects. N8064 is the arc welder and N8064B is the gas welder. See Connecting under More Info to the right, for product details.

AUTOMATIC CURRENT PROTECTION!

At just 3/4" square, this product series includes a state-of-the-art current source which provides a constant 20 ma for LEDs connected to the module. This means any color 20 ma LED can be connected without the need for external current limiting resistors, multiple LEDs can be connected in series (requires a power source of sufficient voltage) and different colors of LEDs can be combined in the same series. All will operate at 20 ma.

For certain applications it may be desirable to have the LED (or series string) connected to operate at less than full brightness. For this purpose, solder pads are included on the back of the module for placement of resistors to adjust of current source output.

Input voltage range 6-16 VDC. Extra power wires included.

This module is designed to produce a short "burst" flash of approximately 1/15 of a second (65-70 ms) at a rate of two times per second (2 Hz). This simulates strobe flashers such as those used on modern-era road work signs.

Campfire / Fireplace Simulator

This simulator produces a random varying change in output intensity for either a single LED, or 2 series-wired LEDs. Two LEDs will provide double the light output. The effect realistically mimics the crackling fire of a campfire. Perfect to add a road or trailside scene of a campfire or picnic BBQ. If used with our Nano LEDs even the smallest scale scene can enjoy the realism this effect produces.

Produces a flash of 3/4 of a second (700-750 ms) with a 50% duty cycle (equal on and off periods). This simulates the style of flasher used for various modern-era traffic signals, certain highway/roadway conditions, air traffic clearance for buildings/radio towers, etc.

Produces a flash with a 50% duty cycle (equal on and off times). Rate of flash is adjustable from 30 flashes per second (33 ms) to one flash every 3 seconds. This adjustment is made by rotating the slotted center of a variable resistor (bottom right corner of flasher). This flexibility allows for adaptation to a wide variety of warning and attention lighting.

Supports up to 200mA and 18VDC per output channel

This module creates an alternating flash between a pair (or pairs) of LEDs of approximately 3/4 of a second and 50% duty cycle. This is a typical sequence for many modern-day traffic warnings such as school zones, traffic revisions, low bridges, etc. This product supports "common anode" devices, see More Info for details.
