REMOTE CONTROL LIGHT TRANSMITTER |
摘要 |
A light transmitter for use in a light activated T.V. remote control system. A modified cylindrical lens having a wide horizontal dispersion angle and a reduced vertical dispersion angle is directly coupled to a light emitting diode. The resulting combination provides a controlled light dispersion suitable for transmitting to a distant receiver location. |
