Local CU Phosco P567As

The P567A made its Derbyshire début in late 2012, using either 4, 6 or 8 LEDs (depending on the requirements for individual schemes) mounted to the inside walls of the canopy. At this time, this variant of the P567A was new to the market and was used by the local authority as something of a trial for a side road LED lantern that would offer good column spacings whilst remaining affordable - always a key factor.

This 4 LED P567A is installed beneath a railway bridge near Chesterfield Town Centre. Owing to limited clearances above the lantern, it is fitted to a 4 m mid-hinged column.

 

The lantern is unusual in that it is not fitted with a photocell - it runs constantly throughout the day and night. The thinking behind this was that, because the lantern does not have a clear upward view of the sky, it would tend to remain lit for much of the day anyway - the apparently bright surroundings seen in the above photograph are exaggerated by the camera. As can be seen below, any sort of photocell control would quickly have lost any sort of accuracy as a result of being splattered by birds using the lantern as a perch-cum-toilet!

 

The internal polished aluminium reflector panels produce an unusual beam pattern when the lantern is viewed from the front.

 

This 4 LED P567A is one of several that, in early 2014, were retro-fitted to the existing 5 m hinged columns on a footpath leading through the park in Riddings. The footpath at this end emerges on Park Side; the first column passed after leaving the footpath is installed at the former location of my own cast iron column.

 

The previous lantern at this location was a Philips 'Streetfighter' SGS 101 running a 50 W SON-T lamp. Conversely, the 4 LED lantern runs at approximately 20 W.

 

The optical system in these lanterns comprises a series of highly reflective surfaces surrounding the LEDs.

 

Remaining in Riddings for the moment, this 4 LED example is situated on the junction of Church Street and Park Mews.

 

As the P567A was designed for running traditional 'lamp' light sources, when adapted for LED operation, a large portion at the front of the lantern is unused.

 

This is one of several P567As installed on Park Mews itself in 2013.

 

A Zodion SS6 35 Lux photocell is employed here.

 

This 5 m column supporting a 4 LED P567A in Long Eaton replaced a sleeved Stanton 10F concrete column supporting a Philips MI 26 35 W SOX lantern. The old column was installed at the front of the footway (its former position can just be seen in the tarmac).

 

This view demonstrates the slight depth to the lantern's bowl.

 

Half of the lantern's LED complement can be seen here.

 

This P567A in Swadlincote is of the 6 LED variety, and is seen attached to the spigot of a 6 m Mallatite column.

 

The lantern is switched using a Zodion Super6 photocell. Three of the LED chips can be glimpsed inside the lantern, at about the middle portion of the bowl. A mirror image of this setup exists on the inside of the facing side of the canopy.

 
 

This 6 LED example was one of two that were installed on Ryknield Road, Kilburn, in 2013 after traffic signals were installed at a nearby junction. The column in the foreground replaced a Stanton 1806 concrete column supporting a Thorn Beta 2 55 W SOX lantern at the same location; the column in the background was a new position.

 
 
 
 

The P567A was also retro-fitted to existing columns; the tree-lined section of Newton Road in Tibshelf saw its 55 W SOX lanterns replaced with 6 LED lanterns in late 2013.

 

An ELECO GR 501 lantern was removed here.

 

Meanwhile, a GEC Z9536 was formerly fitted here.

 

The P567A incorporates the now familiar "trapdoor" means of allowing side-entry or post-top mounting.

 

This version, again 6 LED, resides on an industrial estate in Chesterfield.

 

An issue that was quickly discovered when these lanterns started being retro-fitted to the hockey stick columns that are prevalent around the town was that the natural tilt of the bracket section of these columns caused the main beam of these lanterns to be cast too far forwards, resulting (in some cases) in the light shining in through windows of houses opposite. A solution was found involving a cranked adaptor that fitted between the end of the column and the lantern; this lessened the lantern tilt to a more acceptable position.

 
 

This 8 LED version is one of several installed on Market Street, Ilkeston in 2013.

 

The full complement of LEDs can be seen on the internal circuit board this time.
