As most led product with constant current driver , LED street light have 5 important parts :
LED driver , brands as meanwell sosen philips osram inventronics moso ...
LEDs , brands as lumileds philips osram samsung Nichia cree bridgelux San'an
Housing , there are housing manufactures , some LED street light producers have their own design mould hosing .
PCB , aluminium PCB LED board , to fix the LEDs and make them in series and parallel , and get power from the driver , transmit heat from LEDs to the housing .
Lens , to control the beam angle of the LED , to make them suitable for street lighting
Poweroff protector , surge protector , nema base are not essential parts for a led street light to work , but important part to make a better led street light .
Other parts in the picture belongs to the housing of the LED street light .
Normally the housing would not have problem while the cooling and waterproof would not have problem , most problems happen to the driver or LEDs .
While driver and LEDs have problems , we have to replace the damage parts , the replacements could get from the market or producer .
If the driver damaged , the new driver should have same input voltage , same output voltage and current , or the street light would not work . For example , while the old driver output is 58V 2A , the new driver is 36W 1A , after replacement , the LED street light would not work , or could work but couldn't have same performance as before.
If the LEDs failed , have the replace the whole LED board , only replace the damaged LEDs need specially tools and knowledge . Only the replace the LED board , if not from the producer , would be very hard to find LED PCB that have same size , hole position , and LED quantity , sery and parreal , the best way is to ask the producer to offer replacements , and tell them the product model and the character on the PCB .
