Local OrangeTEK Voyagers
In Derbyshire, the Voyager can be seen at mounting heights ranging from 5 m to 8 m; the varying quantity of LEDs, along with their running current, allowing flexibility in providing different light levels at these heights.
This example is to be found on a side street in Clay Cross; it being installed, along with the column, in September 2017 as a replacement for an older 5 m column supporting an ELECO GR 5011 35 Watt SOX lantern.
A SELC / Westire AcRo photocell set at 35 Lux provides a means of switching the lantern on and off as necessary.
This close-up of the label tells us all that we would ever wish to know about the lantern - in operation, the 4000 K LEDs are driven at 300 mA, with a total power consumption of 13 Watt; however, there is a dimming regime incorporated into the LED driver - the lantern runs at 100% operation from dusk until 21:30. From then until midnight, the output is reduced to 75% operation. Between midnight and 05:00, the output reduces again; this time, to 50%. The output increases back to 75% from then until 06:00. Finally, full brightness is returned after 06:00 until dawn. The Time Zone is described as "London", although, there is no mention of whether this is GMT, BST or both. The beam distribution on this example is described as 'MDE' - for roads of a 'medium' width. Meanwhile, the address for the company is given as the 5th Floor of 192 Dadun Road, in the Nantun District of Taichung City, Taiwan...or here, in other words! A far cry from the very rural Staffordshire base for OrangeTEK's UK office. Curiously, while the uppermost label states a manufacture date of March 2017, the lower label suggests a manufacture date of December 2016 instead. The close-up image also reveals that the lantern is set to a tilt of five degrees above the horizontal.
An air gap is provided at the front of the lantern as a means of dissipating heat away from the LEDs. Although the lantern appears to be running 30 LEDs, many of these positions are blank on the circuit board. Only the two rows that border the centre row are equipped with LEDs, making the actual total 12.
Elsewhere in Clay Cross is this example attached to a 6 m column.
The overall appearance of the lantern is no different from the example seen above.
Only when the label is zoomed in on do the changes begin to be spotted. Whilst the running current remains at 300 mA, the wattage is now 24 Watt, owing to the inclusion of more LEDs. This is an older lantern, as the individual identification is provided with a couple of barcodes, instead of the more modern QR-type code seen above. The registered address in Taiwan is also different; here it is listed as 'OMA Lighting Co. Ltd', which is based on the 11th Floor of 90 Xingde Road, in the Sanchong District of New Taipei City, Taiwan, which can be seen here.
The narrow profile of the lantern can be appreciated here.
Access to the internal wiring of the lantern is gained by releasing the two stainless steel catches that are fitted to the sides of the lantern.
Several other examples are seen along the road.
Here, all but the centre row of the circuit board is equipped with LEDs.
Fields Farm Road in Long Eaton is also home to a number of these lanterns. These were installed on new columns in September 2016 and replaced 8 m columns supporting (mostly) 90 Watt SOX lanterns.
As with their predecessors, the new columns are 8 m in height.
Once again, the same basic lantern is fitted.
The lantern measures 621 mm (24.44 in) × 167 mm (6.57 in). The full complement of 30 LEDs are fitted here. Let's have a look at the information label towards the rear of the lantern...
This time, the LEDs are driven at 700 mA, with a total power consumption of 66 Watt; however, the same dimming regime is employed. The beam distribution on this example is described as 'NDE' - for 'narrow' roads.
Further examples are seen after the bend is traversed.
AcRo photocells are fitted here too.
Several 66 Watt Voyagers were installed along Portland Road in Shirebrook, as part of the construction works for a new supermarket.
Instead of being painted black, as most Voyagers in Derbyshire are, these are painted light grey instead, although there is no difference in the actual operation of the lantern.
The close-up of this label shows that a 'WDE' ("Wide") optic is employed here.
