LIGHTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/126248
Kind Code:
A2
Abstract:
The present design relates to a lighting apparatus which ensures consistent illumination of constant brightness during darkness or in unlit areas. The lighting apparatus comprises: a lamp unit including a plurality of main lamps and a plurality of auxiliary lamps; a detection sensor unit composed of a sensor for detecting a motion of an object; and a controller for controlling operations of the lamp unit and the sensor unit, wherein the auxiliary lamp is adapted to stay turned on at all times, and the main lamp, which operates independently of the auxiliary lamp, is adapted to be turned on if the detection sensor detects a signal, and the controller is adapted to control ON/OFF of the lamp unit according to a signal detected by the detection sensor and to adjust brightness of the entire lamp unit. While the auxiliary lamps stay turned on all the time, the plurality of main lamps are turned on only if the detection sensor detects a signal and are turned off sequentially if a signal for an object in motion is no longer detected. Accordingly, a lighting configuration of constant brightness is consistently provided during darkness or in unlighted areas. This configuration prevents accidents and alleviates feelings of insecurity for persons moving about in a building.
