Abstract

A lighting apparatus includes a driver module, a light source, a main housing and an optical plate. The driver module converts an external power to a driving current. The light source includes multiple LED chips. The light source is coupled to to the drive module to emit a light. The main housing is used for disposing the driver module and the light source. The optical plate is detachably inserted into a sliding track of the main housing via a lateral opening of the main housing so that the optical plate is replaceable. The optical plate changes a light direction of the light emitted by the light source to a light opening. A first surface of the light opening is substantially perpendicular to a second surface of the lateral opening.
