Abstract
PURPOSE: To permit AC driving and at the same time, to increase substrate utilization efficiency by combining a pair of light emission diodes which are connected in parallel in the opposite direction.
CONSTITUTION: n-Type regions 2 and 3 are diffusion-formed on both sides of a p-type semiconductor substrate. An electrode 1' is attached through a low resistant region for ohm contact to the side surface of the substrate 1, an electrode 2', to the region 2, and an electrode 3', to the region 3. In this way , a diode pair consisting of two diodes D1 and D2 was formed and drived by use of AC source. The voltage of the AC source is transformed to ones suitable for driving the diodes D1 and D2 by use of a transformer T, and they are connected to the terminals of the diodes D1 and D2. In addition, an intermediate tap of the transformer T is connected to connection point of the diodes D1 and D2. Thus the diodes alternately emit light every half cycle of AC frequency and therefore continue the emission of light over all the cycle.
