Local OrangeTEK AriaLEDs

As with its sister lantern, the TerraLED, the AriaLED is not especially common in Derbyshire, although it has made an appearance in parts of Derby itself.

This example is attached to a 6m mid-hinged column on a footpath between Brisbane Road and Magdalene Drive in Mickleover. At the time of photographing, in April 2017, the installation was only a matter of weeks old.

 

Twenty closely-spaced LEDs (with a total power consumption of 22 W) are present in this lantern. The top of a conical Royce Thompson Oasis 2000 photocell can be seen fitted to the lantern.

 

Staying in Mickleover, we move to the Spinneybrook Way estate, which dates from 2001/2. AriaLED lanterns were fitted to the existing 5, 6 and 8 m columns on this estate in March 2016; replacing 35 W, 55 W and 90 W SOX lanterns respectively. At the same time, the columns were treated to a new coat of paint - the original 'Derbyshire Green' finish being replaced with the corporate dark blue of the columns installed as part of Derby's Street Lighting PFI. This example is installed on a 5 m column, on the aptly-named Lantern Grove.

 

Again, these lanterns run 20 LEDs. Here, Telensa radio nodes are fitted in place of photocells, in order for the lanterns to be switched remotely, as well as having the ability for their output to be dimmed during quieter periods of the night.

 

A narrow air gap surrounds the LEDs.

 

A 6 m example is observed here.

 

The 10 and 20 LED version of this lantern measures 432 mm (17 inches) in length - at such a diminutive size, even the Telensa node looks out of proportion!

 

The outreach brackets attached to the 8 m columns on this estate were cut back as part of the conversion work, in order for the lantern to be sited closer to the column.

 

The extra height has meant that an additional 20 LEDs are fitted in these lanterns - the modular design of the AriaLED ensuring that a uniform appearance is maintained, even though the lantern length has increased as well - these are 502 mm (19.76 inches).

 

For a brief period, the photocells that had been fitted to the gear-in-head MA 90 lanterns that originally adorned these columns were re-used in some of the new lanterns - perhaps, there had been a supply issue with the Telensa units, which required the new lanterns to be on local photocell control until it could be resolved.

     

The first two columns on the estate have 50 LEDs; the second of which is seen below.

 

Owing to the LED modules being configured in groups of 20, ten blank positions are visible in the front module. This version is 572 mm (22.51 inches) in length.

 

AriaLED lanterns were also to be seen on a housing estate that was being built on the site formerly occupied by Mackworth College. As the new roads had not yet been adopted by the Local Authority at the time of photographing, also in April 2017, all of the lanterns were dayburning, owing to their Telensa nodes having not been programmed in to the remote operation system at the time.

 

Although the LEDs appear to be warm-white in the picture below, they are actually cool-white.

 

All of the AriaLEDs installed for this development are of the 40 LED variety.

 

This estate in Darley Abbey had WRTL Arc lanterns providing its night-time illumination prior to their replacement with AriaLEDs in early 2016.

 

These columns were also repainted when the new lanterns were fitted - notice that the new blue paint doesn't quite extend up to the lantern, revealing the original 'Derbyshire Green' paint beneath.

 

On the night of Thursday, 28th April 2017, some of the Thorn Alpha 2000 lanterns on the A6 'Derby Spur' link road between the A50 and the A6 itself were replaced with AriaLED lanterns.

 

Owing to the lighting being group-controlled, neither the Alpha 2000s, nor the AriaLEDs, are fitted with photocells.

 

I assume that the remaining Alpha 2000s on this road and junction are set to be replaced themselves at some point.

 

The mixture of golden light emitted by the Alpha 2000s and the much whiter light emitted by the AriaLEDs must make for an interesting sight after nightfall.

 

These lanterns are fitted with 50 LEDs, although their running current must be higher, in order for the LEDs to run more brightly at the 10 m mounting height on the heavily-used road.
