Kind Code:
B2
Abstract:
A lighting device with a plurality of light-emitting elements such as light-emitting diodes disposed in an in-line configuration at regular interval on a base plate; and a plurality of reflectors attached to the base plate, the plurality of reflectors being so formed as to cover each of the light-emitting diodes with mixed reflecting surfaces structured by reflecting surfaces which are planar except their lower portions, the planar reflecting surfaces being perpendicular to in-line direction of the light-emitting elements such as diodes, and other side surfaces which are able to mix reflected lights from the light-emitting elements; therefore, the present invention provides economical lighting devices which can illuminate relatively wide area nearly evenly by effectively mixing the lights from the light-emitting elements such as light-emitting diodes, and further which can be used like conventional electric lamps and fluorescent lights.
