LED Spotlighting System for billboards
General description:
LED12.BB-12/24-350 has been properly studied for the use in high luminous efficiency and high Energy saving
applications as in PV stand alone systems. It has been optimized for outdoor lighting as regards fixings and light
projection.
All this is the ideal solution for the lighting of billboards considering also the possibility of a direct connection to
Western Co. charge regulators code SPB-LB, SPB-LR e SPB-LG.
The lamp has got a power supplying and control electronics @ DC low voltage (12-24VDC) which has an average
conversion efficiency > 92% and a control system by microcontroller of the maximum working temperature.
In case of reduced Energy availability it is possible to obtain a consumption saving by using the flux reduction up
to -30%; this function can be activated and managed directly by the PV charge regulators SPB-LB, SPB-LR and
SPB-LG.
Installation procedure:
LED12.BB-12/24-350 has been studied for fixing and installation with adjustable projection angle in outdoor
applications. Having a IP65 degree protection, it provides protection against dust and water. While installing pay
the maximum attention in respecting the polarities and avoid short-circuits; they are destructive and they
annul warranty. Place LED12.BB-12/24-350 having care to block its position using the proper fixings. We
recommend an horizontal installation to avoid dazzling effects, light pollution and a greater quantity of
direct flux.
