Vishay Introduces Streaming Video Product Demonstration of Phototransistor-Based Ambient Light Sensors on Web Site
Video Shows Superior Performance of Vishay’s Ambient Light Sensors With Different Light Sources
MALVERN, Pa. — Feb. 17, 2010 — To assist customers in understanding the advantages of using ambient light sensors in their applications, the Optoelectronics group of Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has added a new streaming video product demonstration to its Web site (http://www.vishay.com).
Vishay’s ambient light sensors feature an exclusive infrared filtering epoxy technology to match the spectral sensitivity of the human eye, with minimal sensitivity to light beyond the visible range. This helps to prevent interference from the infrared component of natural light and artificial lighting such as incandescent and halogen light bulbs. The new five-minute video features a brightness level test which highlights the superior performance of Vishay’s TEMT6200FX01 over competitor and standard silicon phototransistor parts.
The demonstration shows that with different light sources, other technologies show a significant deviation in the brightness level detected. Vishay’s TEMT6200FX01, however, most closely matches the spectral sensitivity of the human eye by showing nearly no deviation.
This level of performance allows Vishay’s ambient light sensors to be used for automatic control of LCD brightness in consumer electronics, where they increase user comfort level and reduce power consumption by turning on keypad backlights only in low ambient conditions, and controlling LCD display brightness to optimize viewing based on ambient light.
