Miscellaneous GLF works at Tirupati Airport.

Supply, installation,testing and commissioning of internally illuminated LED based Mandatory/ Information /Location/VOR check point Runway / Taxiway guidance signage of various sizes made out of 4mm thick glare free poly carbonate sheet at front and body made out of 2.0mmthick powder coated aluminum profile having minimum width of 150mm and supported at back by 50mm dia (Nominal size) die cast aluminum / GI pipe at a separation as required, and frangible coupling as required. Light source shall be high luminous, long life typical 50,000 Hrs type, 0.5 Watt s LED's assembled on aluminum PCB of size 700mm X 20mm and having 11 LED’s per PCB for boards having height 800mm & 500mm X 20mm PCB having 8 LED’s per PCB for board having height 600mm respectively. The thickness of the aluminum PCB should be 2mm in order to ensure proper heat dissipation. These aluminum PCB’s should be placed not more than160mm apart across the length of the board in order to ensure uniform distribution of light across the board. Each board having length from 800mm up to 3000mm should be illuminated by a single converter & by using single isolating transformer of suitable watt age in order to save the capital cost of multiple isolating transformers. Signage shall be suitable for operation on series circuit at variable current from 2.8Amp - 6.6Amp and will give constant brightness for all current variation. All the signage shall have letters and symbols made by computerized cutting of vinyl and pasting on the polycarbonate sheet from inside/outside of the sign face of required color as per ICAO specifications.
