Vishay Semiconductors SurfLight 红外发射器
威世 SurfLight 红外发射器重新界定了红外发射器的性能标准。标准红外发射器从芯片各个方向发光，而 SurfLight 器件则不同，几乎所有光和功率都是由芯片的上侧发射出去的。由于光线集中在表面，客户可获得五倍于标准发射器技术的光线密度。这意味着可减少发射器的数量， 从而降低了整体系统成本。
Nearly all the light and power is emitted out the top of the chip, unlike standard infrared emitters that emit light in all directions. With surface concentrated light, you get up to five times higher intensity than standard emitter technology. This means fewer emitters are needed, lowering the total system cost. Typical applications include miniature light barriers, photo interrupters, optical switch, light curtains, infrared data transmission/communication, smoke detectors, and 3D TV active glasses synchronization.
