A LIGHTING APPARATUS USING MULTI OLED PANEL

摘要

The preset invention relates to a lighting device using a multi OLED panel. More specifically, the present invention provides a lighting device using the multi OLED panel, in which a plurality of OLED panel are connected to one another and used as a single lighting device. The lighting device comprises: an auxiliary light-emitting means which allows light to be incident on a waveguide, which is formed in a non-luminous region between frames of OLED panels when the OLED panels are connected to one another, and allows the non-luminous region to emit light; and a light-emitting control means which controls the OLED panel having relatively low efficiency and the light amount of the auxiliary light-emitting means so as to follow the light amount of the highest-efficiency OLED panel among the OLED panels, based on previously measured light-emitting efficiency with respect to each OLED panel. In a case where a lighting product is manufactured by connecting a plurality of OLED panels, it is possible to obtain the effect of removing another non-luminous region occurring in frames between the OLED panels by allowing light to be incident through the waveguide. Also, the panels having relatively low efficiency are controlled so as to follow the light amount of the highest-efficiency panel after measuring the efficiencies of panels in manufacturing the lighting device and then grouping the panels based on efficiency, thereby improving the light-emitting uniformity of the entire lighting device.
