Abstract
A luminaire comprises a lamp holder, a lamp cover, a light-emitting module, and a light guide element. The lamp cover is assembled to the lamp holder to define an accommodating space therebetween. The lamp holder has a platform part protruding into the accommodating space. The light-emitting module is mounted to the platform part, and includes a circuit board and at least one LED disposed on the circuit board. The light guide element is mounted to the platform part, and covers the light-emitting module. The light guide element has an outer diameter longer than that of the platform part. The light guide element is shaped to allow light emitted from the LED to be transmitted out of the lamp cover through the light guide element in a lateral direction, and thus the view angle of the luminaire is increased.
