Apollo lights the way with LED
Overview
This building at University of Manchester was completed in 2008 and has a maze of inter-linking internal corridors and walk ways. The corridors are like long barrels flying through the sky. Both the corridors and walk ways are lit by LED fittings provided by Apollo Lighting Ltd.
Design Concept
The original concept was to wash all the internal walls of the corridors with colour and for this to be controllable so that any atmosphere could be created in the corridors.
Initially two runs of continuous mounted Arol LED strip were proposed, one each side of the corridor. This was eventually reduced to just one side.
Mounting
The Arol strips are mounted inside a bespoke mounting channel provided by the contractor to prevent pedestrians from looking directly in to the LED chip.
The 36w drivers for the LED strips are mounted remotely from the LED luminaires to aid with any maintenance or re-addressing that might be required through the life of the installation.
The majority of the LED strips require one driver per luminaire. A few smaller units were required to ensure a continuous line of light without any breaks. Some units split the output of one driver to more than one LED housing.
Fittings
A total of over 130 Arol strips are installed along these corridors, each strip is only 50mm wide and 28mm high. The majority of strips house 36 Luxeon LEDs, 12 red, 12 green and 12 blue. All the LEDs have and optic fixed to the front, the optic used for this installation was an oval optic with a beam angle of 5° x 20°.
Each Arol strip has a temperature detector mounted in its circuit board, if the specified optimum operating temperature is exceeded the driver will automatically reduce the power of the LEDs until the temperature is within range.
As the drivers are mounted up to 50m away from the LEDs then the cabling was an important factor to ensure the maximum output from the LED could be achieved. Working closely with the electrical contractor Apollo Lighting assisted with all the technical aspects of the installation
