Abstract
A lighting apparatus having high operation reliability includes a first lighting unit with a first turn-on voltage and a second lighting unit with a second turn-on voltage greater than the first turn-on voltage. The lighting apparatus is put in use for generating output light according to a driving current flowing through the first lighting unit or the second lighting unit. The first lighting unit is capable of generating output light having a first brightness according to the driving current. The second lighting unit, electrically connected in parallel with the first lighting unit, is capable of generating output light having a second brightness according to the driving current. The second brightness is preferably identical to the first brightness.
