Abstract
Official abstract text for this publication.
An LED light bar includes a PCB and a plurality of LED lamps mounted to and electrically connected with the PCB. Each of the LED lamps has a light emission face that is perpendicular to the PCB. The LED lamps at two opposite ends are arranged to have the light emission faces thereof angularly shifted in directions away from the light emission faces of the LED lamps in the middle to thereby increase light irradiation range of the LED light bar. With the LED lamps at two ends of the LED light bar being arranged to have light emission faces thereof angularly shifted so as to form a predetermined included angle between the light emission faces of the LED lamps and a light incidence face of the light guide plate, the irradiation range of light from the LED light bar is increased.
First claim
Opening claim text (preview).
What is claimed is: 1. An LED light bar adapted to emit light to irradiate a light incidence face of a light guide plate, the LED light bar comprising a PCB and a plurality of LED lamps mounted to and electrically connected with the PCB, each of the LED lamps having a light emission face that is perpendicular to the PCB, the LED lamps in a middle portion of the LED light bar being arranged to have the light emission faces thereof arranged in a straight line corresponding to the lig…
