ABSTRACT:
A lighting apparatus includes a heat-dissipating unit, a circuit board unit, and a lighting unit. The heat-dissipating unit includes a base wall that extends in a longitudinal direction. The base wall has a top side and a bottom side formed with a convex surface portion. The circuit board unit is disposed on the base wall. The lighting unit includes an outer pair of light emitting sets and at least one other light emitting set disposed between the outer pair of the light emitting sets. The light emitting sets are disposed on the convex surface portion and are coupled electrically to the circuit board unit. Each of the light emitting sets has a plurality of light emitting units that are spaced apart from each other. A number of the light emitting units in each light emitting set in the outer pair is larger than a number of the light emitting units in each of the other light emitting sets.
