SteFly Canopy Flasher red upgrade
Original price was: 178,50 €.119,00 €Current price is: 119,00 €.
incl. 19% VAT plus shipping
After consultation, send us your green SteFly canopy flasher and we will exchange it for a red canopy flasher. Please also enter in the “AIRCRAFT TYPE” field if you would like us to optimize the cable length of your new canopy flasher (e.g. shorten the cable between the canopy flasher and the canopy contact by 2 cm).
Delivery time: 5-7 Werktage / Business Days
Scope of Delivery:
- SteFly canopy flasher with red LEDs and black aluminum / polymer housing
- Control box is not included, as this can be taken over from the green canopy flasher
- Masking foil template for precise alignment of the canopy flasher in the direction of flight
- Cable holder for tidy cable routing along the canopy frame
- For flashers with canopy contact: new mounting bracket for attaching the canopy contact to the acrylic glass
Highlights of Function and Design
- 6 red LEDs of the latest generation, which can be operated at a very high current for maximum brightness thanks to the aluminum heat sink
- The light beam formed by the lenses warns oncoming aircraft, especially from the front
- At the same time, the high-performance LEDs produce enough light to widen the angle of reflected beam, so that aircraft appearing diagonally in front of your own glider are also warned
- Stray light is not absorbed by the housing, but is instead reflected by the high-quality Reflective foil, as used on road signs. Therefore all the light coming out of the LEDs contributes to warn other pilots.
The elegant canopy flasher with the “curved design”
The development goal was to design the brightest red canopy flasher. Nevertheless, the housing had to be smaller than that of other canopy flashers on the market. How can that be achieved?
FORM FOLLOWS FUNCTION
By arranging the individual LEDs at the smallest possible distance from the canopy glass and having the housing follow this curved contour, maximum space is left under the housing, e.g. for the ventilation flap. The flasher can be mounted far forward on the canopy. Together with the small dimensions, this allows the pilot to maintain a full view to the front. The canopy ventilation is also obstructed as little as possible.
There are again several housing shapes to choose from so that we can always offer the best solution for the individual canopy curvatures and space requirements of different aircraft types.
Aluminum Housing for Thermal Management
Red LEDs produce a lower luminous flux compared to green LEDs with the same energy input. The energy that is not converted into light must be dissipated into the environment as waste heat. This requires an efficient waste heat concept and, in particular, a heat sink with a large surface area made of a material with high thermal conductivity. All plastics have a very low thermal conductivity of 0.23 W/(m*K) for nylon, for example. Aluminum, on the other hand, has a thermal conductivity of 220 W/(m*K) - that is 950 times better! A heat sink made of plastic is nearly useless and can only be used as a design element. Thanks to its greater thermal mass, an aluminum heat sink absorbs the heat emitted by the LEDs with every flash and continuously transfers it to the cooler outer surface of the heat sink. From there, it is absorbed by the ambient air.
In a nutshell:
- We rely on a milled aluminum heat sink for optimum cooling of the LEDs
- Perfect heat transfer for long LED life and high light output even in summer temperatures and with high solar radiation, because a cooler LED has a higher degree of efficiency
- Thanks to the heat sink, the 6 high-performance LEDs can be operated with a current and brightness that would be far from possible with a plastic heat sink
- The housing of the flasher is black anodized and provides the SteFly logo .
The housing also convinces with many other details:
- The front part of the housing is manufactured in a 3D laser-sintering process made from high-performance polyamide .
- To visually check whether and exactly when flashes of light are emitted, an optical light guide was integrated into the heat sink
- Double-sided 3M VHB acrylic tape reliably connects canopy flasher and acrylic glass
