It is a wireless system, specially used in temporary work zones, it works with 2 batteries (one for each trailer) of 12V that are located in a proper battery container where are also located the central board (one for each trailer).
Each trailer is equipped with back side wheels and handle shaft, that make the system very suitable for quick installation and removal. The compact and foldable structure of the traffic light housing makes it easy for its transportation and its moving (loading and unloading from van).
Working description The led traffic light system works with a microprocessor system that permits to set very easily the time of the red and green lights. The microprocessor of the traffic light permits to set 3 times:
- red/red
- green 1
- green 2
The maximum time for each phase is 99 seconds with 1 second each step, it is also possible to reach 495 seconds with 5 seconds each step.
The standard time for the flashing yellow is 5 seconds. During the flashing mode the central boards go on with the intermittent sequence, and so when the flashing configurations stop the 2 central boards are still synchronized together and go on their sequence as the one already set from the user at the beginning of the operation.
Led optics control: If one led optics doesn't work it is possible to see on the display this problem of working and in case of the red optics problem of working, the traffic light will start flash in yellow colour. In order to let it works properly it is necessary to change the red optics with a new one.
Battery level control: If the battery is under the level, on the display is shown the Lb word.
Breaking of protection fuse control: If the fuse is broken a red light starts flash.
Inside the battery box there is also an internal battery to memo the setting data, it is also used when is necessary to change the power supply batteries as afterwards it is not necessary to synchronize again the 2 traffic lights.
Decrease of consumption The traffic light is equipped with a photo-cell control (located in the green optics) that permits to check the environmental brightness and to regulate the led brightness intensity in any situation.
Using the automatic regulation of the brightness intensity is possible to have several advantages; on first it is possible to prevent (during very shining days) that the traffic light is hardly visible, and that during the night the traffic light makes bother or glare to the drivers.
The automatic regulation of the brightness also permits to reduce the consumption; in fact the control of the light intensity, regulated by the central boards, permits to have lower energy consumption, only when it is necessary.
Thanks to the used of led optics the led traffic light consumption is 6 times lower than the traditional traffic light with a bulb of 25W, for this reason it is possible to use less powered battery (70Ah instead of 180Ah) and an autonomy of 6 days (instead of 4 days of autonomy using a 25W bulb).

Sun phantom effect The sun-phantom effect (the reflection through the lens of external light) is a problem mainly observed with traditional traffic lights. The effect has been solved through the introduction of a coloured LED mounted onto the optics. As a result, any reflected sun-light directed through the lens becomes neutralized and consequently, will no effect on the illuminated colour. Further, in order to maximize the contrast in light between the 3 optics, both the housing and background of each lens has been painted black.
