摘要： An optical communication module comprises a light emitting element for generating the transmission signal, a condenser lens for connecting the transmission signal light from the light emitting element to the light transmission line, a light receiving element for receiving the receiving signal light from the light transmission line, and a package that covers the light emitting element and the light receiving element, and uses the condenser lens as an opening window, wherein the wavelength selective film for allowing the required waveband light to transmit and the unwanted waveband light to reflect is coated on the transparent member installed on or in the vicinity of the convex surface of the condenser lens. As a result, a bi-directional optical communication module of an inexpensive construction can be obtained, which can receive the desired waveband light only without using a special component such as a wave separator and does not return the unwanted waveband light to the light transmission line.

摘要： A blue light emitting element B and green light emitting element G are coupled in series with each other to constitute a ring. The coupling points of these elements are used as a first connecting point 24 and a second connecting point 26. The one electrode of a red light emitting element R is connected to the first input terminal 24 and the other electrode thereof is used as a third terminal. By adjusting the voltages to be applied to the input terminals 24, 26 and 28, the light emitting state of each light emitting element is adjusted. Therefore, it is only required that wiring is made for these three input terminals. With the input state of the input terminal 24 being fixed, only the input states of the input terminals 26 and 28 are changed using switches SW1 and SW2 so that the light emitting state of each light emitting element can be adjusted. Thus, the device structure inclusive of its wiring can be further simplified, thereby realizing high density display of the light emitting device.
