Replacement of Conventional Signages with LED Signages in Operational Area at Aurangabad Airport.

Amount

Retro-Fit conversion of existing signage board by replacing internal source & driver with high luminous long life typically 50,000 Hrs. type, LED's assembled on aluminium PCB of size 700mm X 20mm and having 11 LED's per PCB for boards having height 850mm. The thickness of the aluminium PCB should be 2mm in order to ensure proper heat dissipation. These aluminium PCB's should be placed at a distance of less than 160mm apart across the length of the board in orderto ensure uniform distribution of light across the signages board. Each board having length from 650mm up to 3000mm should be illuminated by a single multi-driver & by using existing isolating transformer. The entire signboard should work on taxiway current (supplied from CCR's) varying from 2.8 to 6.6 Amp & should have uniform brightness across the entire range of current variation from 2.8 Amp to 6.6 Amp. The illumination of the sign board should be as per relevant ICAO guidline and should be suitable for outdoor installation , LED lights , signage, components, driver will be as per technical specifications given in Tender Document etc. as per site requirement.

Dismantling of Existing signage form Airside location and taking to Power house/suitable location at site for retro-fit modifications, cleaning the entire board and re fixing the sign board at original location after completion of retro-fit work including connection to isolating transformer etc. as per site requirement.

Supply, of internally illuminated LED based Signage boards with central split type opening for easy maintenance mandatory/information signages of various sizes made out of 4mm thick glare free poly carbonate sheet at front and body (all sides except front ) made out of 2.0mm thick powder coated anodized aluminum profile having minimum width of 150mm and supported at back by 50mm dia (Nominal size) die cast aluminum pipe as per site requirement and frangible coupling as per ICAO norms. Light source shall be highly luminous, long life typical 50,000 Hrs. type, 11 -Nos LED’s assembled on each PCB of minimum size 700mm x 20mm x 2mm for boards having height 600mm or more. Efficiency of LED shall have delivered minimum output 110 lumens per watt and colour temperature should be more than 5000 Kelvin with proper heat dissipation. The aluminum PCB’s should be placed across the length of the board in order to ensure uniform distribution of light across the board. The signage boards with length varying from 900 mm to 2000mm shall be suitable for operation on 230 V AC , 50 Hz, single phase, including supply and installation of suitable capacity/wattage electronic converters (driver) etc. 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 etc. , suitable for outdoor installation, , LED lights , signage, components, driver will be as per technical specifications given in Tender Document etc. as per site requirement.
