ru_translateУважаемые сообщники! Не могу разобраться с двумя аббревиатурами. Сначала решила, что первые лампы (PL) -- фотолюминесцентные, но не найдя расшифровки SL что-то уже и в этом сомневаюсь. На всякий случай абзац целиком:
It introduced the Compact Audio Cassette in 1963 and produced its first integrated circuits in 1965. The flow of exciting new products and ideas continued throughout the 1970s: research in lighting contributed to the new PL and SL energy-saving lamps; other key breakthroughs came in the processing, storage and transmission of images, sound and data where Philips Research made key breakthroughs, resulting in the inventions of the LaserVision optical disc, the Compact Disc and optical telecommunication systems.
Заранее спасибо за отклики.
