Semiconductor lighting device for use as e.g. LCD backlight, has lighting units installed on substrate and encapsulated in translucent resin, where units with different directional characteristics are arranged adjacent to each other

摘要

The device has a set of semiconductor lighting units (3a, 3b, 3c) installed on a substrate, and n-electrodes and p-electrodes, which are connected by chip bonding or wire bonding in an alternative manner. The lighting units are encapsulated in a translucent resin that contains phosphorus, and have two types of different directional characteristics, where the lighting units with different directional characteristics are arranged adjacent to each other.
