OSRAM unveils the first flush-mountable infrared LED
The T-shaped transmitter takes up only 4.6 square millimeters (mm2) of board space and emits a powerful focused beam to the side. The beam angle of +/-25 degrees is created by an integrated reflector – a real plus point in terms of space requirements. The SFH 4140 produces an impressive 50 milliwatts per steradiant (mW/sr) as its typical radiant intensity from 100 mA; therefore it achieves the ranges needed for remote control functions. The wavelength of 940 nanometers is also perfect for meeting the requirements of this application.
This component is OSRAM Opto Semiconductors' contribution to the trend of turning smartphones and tablet computers into universal remote controls, particularly for home entertainment electronics. If the device is equipped with the appropriate infrared transmitter diode then the diode can be controlled with a suitable app. Where classic remote controls traditionally use radial infrared LEDs, this option is not an attractive one for slim smartphones and tablets. These need a low-profile SMT solution which can nevertheless operate over the required distance. Up to now, manufacturers have been using transmitters such as Midled, Mini Midled and Chipled. The powerful T-Midled SFH 4140 is OSRAM Opto Semiconductors' latest addition to its portfolio of remote control transmitters, a no-compromise low-profile solution for which there will almost always be sufficient space.
