0% 10% 25% 100% CONFIGURATION The light fitting configuration includes an analysis of the potential incoming energy (geographical location of the light fitting) and a detailed analysis of the physical location of the light fitting (proximity of buildings or trees). Lastly, an analysis of the level of requested service and performance will be imple- mented (luminance levels, operation hours, potential discontinuity in the service, if any). TECHNICAL DATA Total number of heads with solar panels: 10 Solar panel voltage in open circuit: 10V max Peak power for each panel: about 75 W Number of heads with COB LEDs: 4 Installed power for each light head: 20 W at 1000mA. LEDs color temperature: 3000K, 3SDCM Maximum luminous flux for each head: minimum 2200 lm. Total number of “stems”: 10 LED power for each “stem”: about 1 W with a power supply of 350mA. 2 batteries Battery voltage: 12V Single battery capacity: 230 Ah 2 batteries boxes 1 box for 10 light stem panels wiring connection 1 box of 10 luminous “stems” wiring connection 1 power supply and battery connection box and power supply for LED heads + luminous “stems” + wireless charging / presence sensors (optional) WORKING Solar Tree was designed for operation in the HYBRID configuration: in addition to the batteries, generally of the appropriate capacity to contain energy for autonomous operation for up to 7-10 days (with an energy-saving operation cycle, better specified below) with full charge, connection with the mains is provided for energy supply to the appliances (via an appropriate DC power unit connected with the mains) when the batteries are depleted. This is to ensure full service availability even in case of persistent bad weather and/or reduced sun irradiation or 100% use of the luminous performance of the appliance, or anyway when the energy balance is negative. At dusk (recognized by determination of the dawn and sunset time entered into the calculation routine of the management programme or otherwise), the LED sources are turned on until dawn according to the pre-set duty-cycle. In “HYBRID” appliances, the system draws energy from the batteries until these fall to the lower charge limit, then switches automatically to the mains. For appliances based on this configuration, if mains connections coincided with the desired switching time of the public lighting appliances to which the Solar Tree functionally refers, appropriate settings would ensure that the voltage available upon powering is interpreted as a start signal for the Solar Tree and vice versa in case of disconnection from the mains. WORKING PROGRAMS Two operating modes are available to satisfy individual needs – Manual and Automatic. The Automatic mode can, in turn, be configured in three different ways, according to the desired performance and energy saving attitude. More specifically: AUTO ECO: 100% operation at times of maximum attendance of the venue, limited operation of the LED heads only in the middle of the night (to ensure average 8 lux ground illumination, the LED sources are turned on and adjusted to approximately 25% of their nominal operating power from sunset to dawn. This mode is recommended to tend to full operation coverage even during the fall/winter in view of energy balance). AUTO 100% : an operation mode that tends to ensure maximum operating performance of the appliance adjusting to the increased input of solar energy (if any). CUSTOMIZED: the user can select the desired operating times and profiles. The above-described profiles can be associated with deadlines and, therefore, be selected alternatively. MANUAL: can be enabled by the user in case of special events and/or needs. The user can access the “fine” adjustment menu for selection on a 0-100% scale of the flow emitted by the individual LED heads and by the bunch of stems. The sources then remain switched on and adjusted according to the user’s settings until switching off or returning to the automatic mode under the user’s control. The structure consists of curved steel poles of different diameters and heights, reaching a maximum total 6.4m height above road level. The system includes 10 “grass blades” with 3mm-thick poles with a 42mm diameter, fitted with 1 1W terminal LED protected by a PMMA diffuser screen, and 10 4mm-thick poles with a 76mm diameter supporting the heads. The heads are composed by an anodized aluminum structure and, in the lower part, of a UV-resistant PC cover, which ensures protection against water and dust. They are all equipped with solar panels. The poles are painted with green epoxy paint for exteriors, with iridescent effects on a galvanized base substrate. Four of the ten heads (all with photovoltaic cells on the top) are fitted with a COB LED unit with a warm white colour temperature, for an asymmetric direct emission. The base is made of hot-zinc coated sheet steel designed for enclosure in a plinth of the appropriate size, not provided with the appliance, to be sunk into the ground. Alternatively a base is available, also made of zinc-coated steel with reinforced concrete stabilizing units forming a round seat. In this case the base can simply rest on the ground, even if ground fixing is always recommended. The connection/cabling elements, as well as the control and charging boards, are contained in multiple water-tight boxes with plug-and-socket connectors with protection rating IP65 or higher, and located either in appropriate spots at the foot of the base for easy inspection and maintenance, or inside the concrete stabilizing unit, as specified in detail for the Solar Tree version constituting the object of the supply. The airtight accumulators are contained in specific boxes that allow, on one hand, to protect the battery mechanically and from outer agents and, on the other to release any gas discharges, to be provided for by the law. → → → → → → → → 898 899
