摘要
A voltage regulator unit (10) for regulating electrical power supplied to a lamp in a street lighting apparatus (2) is disclosed. The voltage regulator unit comprises an input part (12) for receiving electrical power, a first output part (28) for supplying electrical power a lamp, and a second output part (12) for supplying electrical power to a further voltage regulator unit. A transformer (40) has a primary winding receiving electrical current from the input part and a secondary winding (38). First (34) and second (36) relays selectively connect the secondary winding to the second output part.
