LED Lighting sources are ideally suited for applications where lighting requirements are principally dictated by the need to be seen. (Traffic signals, navigational beacons, obstruction lighting, signage, runway lighting, brake lights...)

Innovative traffic design and signaling, designed as per your Specs. for their lighting needs. Amber alert, Futuristic iintersection control, "Emergency Vehicle Approaching", signs have been designed and delivered.

1.0 General Display Characteristics
The unit shall display a legend in accordance with the requirements in the federal Standard Highway Signs Book. The message shall be bright in color against an f l a t black background. The color of the illuminated message is a function of the
Specified LED. The display shall consist of an array of LEDs

Which f o r m the legend. The sign shall be discernible attracting
Attention under any lighting conditions varying from t o t an l
darkness to bright s u n light. The message shall be clearly legible
at a minimum of 300 ft (91 meters). When n o t energized, the sign
Shall be blanked out (unreadable) with no phantom images,
Regardless of solar intensity or direction. The sign shall have a
Limited viewing a n g l e of 30' centered about the optical axis and
Perpendicular to the surface of t h e matrix display. The unit
Shall be capable of continuous operation over a temperature range
Of -35'F to +130’F? (-37C to +74C) -
2.0 LED Module

The LEDs shall be mounted into one and one-half inch pixels and
Arranged on t h e front aluminum faceplate to display the requested
Message. The LED pixel unit shall be completely self contained
and removable from the door.

3.0 Housing
The housing and door assembly shall be black powder coated
Aluminum with an overall material thickness of 0.125 inches
(0.3cm). All seams shall be continuously welded, an internal
Stiffening rib of 0.125 inch (0.3m) aluminum shall be welded to
The housing f o r additional strength and rigidity. Aluminum
Piano hinge and 8 latches will be provided to hold the door shut.
A gasket will be used to seal the door of the housing. All nuts,
Bolts, screws, washers, lock washers, and other fastening
Materials shall be stainless steel.
4.0 Electrical Requirements

Wiring shall be made via a barrier terminal strip. All wiring
Shall be #16 gauge wires.
5.0 Illumination System Requirements
The sign shall be illuminated by super bright LEDs. Each LED
Shall be rated for 100,000 hours of continuous operation with a
Luminous intensity of 1200 (typically) mcd at 20ma. In a standard
LED sign, the LEDs shall have the following characteristics:
Size T-1 3/4
Peak Wave Length 630 nm
Brightness 1400 (typically) mcd
6.0 Optional Dimmer
There shall be available, as an option, a photocell and dimming
Circuit, shielded from any direct light source, which are capable
Of automatically adjusting the message light output in response
To changes in ambient light conditions. The photoelectric cell
Shall operate automatically to brighten the intensity of the sign
Illumination to one-half of t h e daylight illumination as
Nighttime occurs. Pixels shall be wired t o utilize h a l f the U D s
In dim mode during one 24 hour cycle and alternately the second
Half of the pixel in the second 24 hour cycle to evenly balance
The use of all LEDs.
