Abstract
A luminaire includes a lamp holder, a lamp cover and a plurality of first light-emitting modules. The lamp holder has a top surface, a plurality of protrusions protruding upwardly from the top surface. Each of the protrusions has an inclined surface. The lap cover is connected to the lamp holder, and covers the top surface and the inclined surfaces. Each of the first light-emitting modules includes a first light-emitting element. The view angle of the luminaire can be increased due to disposition of the first light-emitting elements on the inclined surfaces of the protrusions. Furthermore, since the first light-emitting elements are disposed on the protrusions, heat can be dissipated easily from the first light-emitting elements.
