LED street lighting from Greenbridge Energy Australia
The streetlight fitting consists of a single unit which houses the
LED plate, the control unit and switching power supplier. It is connected to;
- solar cell panel (with a power rating that ranges from 50 to 140 W, depending on
the application and lamp power);
- 12 V storage battery (with a capacity ranging from 120 to 144 Ah, depending on
the application).
The structure of the light fitting comprises;
- casing and dissipater made of aluminium;
- cover in grey coloured (RAL 7035) shockproof polycarbonate, stabilized against
deterioration caused by UV radiation;
- front cap: the structure is protected at the front by flat glass. This is fixed
to the light fitting by strong hinges that allow the unit to be serviced without the
cap having to be removed. The cap is closed by three stainless steel clips and a seal,
ensuring that the LED compartment is perfectly tight;
- 12 Vdc power supply. An easily removable powering plate contains the electrical
equipment, which comprises an electronic control and monitoring circuit and a high
frequency switching power supplier; During the winter months or lengthy periods of bad
weather, the control circuit will automatically reduce the brightness of the LEDs
during the central hours of the night and depending on the battery charge, thus saving
the stored energy so that it is available for the following nights.
