Patent ID: 10784425

Abstract:
The light illumination module includes a substrate, a plurality of wiring patterns formed in parallel on the substrate, and a plurality of LED devices disposed on the wiring patterns. Each wiring pattern has a stripe-shaped portion extending in a first direction, a first protrusion portion protruding in a second direction, and a second protrusion portion protruding in an opposite direction. The first and second protrusion portions are formed in an alternating manner along the first direction, and the LED devices are disposed on the first protrusion portion and the stripe-shaped portion at a location corresponding to the second protrusion portion. A first electrode of each LED device is electrically connected to the first protrusion portion or the stripe-shaped portion immediately below, and a second electrode of each LED device is electrically connected to the stripe-shaped portion or the second protrusion portion of an adjacent wiring pattern with a wire.
