UHP (lamp)
The ultra-high-performance lamp, a high-pressure mercury arc lamp often known by the Philips trademark UHP, was originally known as the ultra-high-pressure lamp. It was developed by Philips in 1995 for use in commercial projection systems, home theatre projectors, MD-PTVs and video walls. Unlike other common mercury vapor lamps used in projection systems, it is not a metal halide lamp, but uses only mercury. Philips claims a lifetime of over 10,000 hours for the lamps. These lamps are highly efficient compared to other projection lamps – a single 132 watt UHP lamp is used by DLP manufacturers such as Samsung and RCA to power their DLP rear-projection TV lines. Manufacturers of high pressure discharge lamps (UHP or similar) include:
- Iwasaki (HSCR)
- Osram/Sylvania (P-VIP)
- Panasonic, Matsushita (HS)
- Philips (UHP)
- Phoenix (SHP)
- Ushio (NSH)
