ams OSRAM adds RGB versions of OSTAR Projection Compact LEDs
ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has added Red, True Green and Blue colors to its OSTAR Projection Compact family of low-profile, ultra-high-brightness LEDs, to enable manufacturers of machine vision systems or stage lighting fixtures to create more powerful and slimmer products. ams OSRAM already offered a White option in this package specification (at that time known as OSLON Boost).
The new LEDs are suitable for premium high-power lighting products because of their high current density and very high brightness. Featuring a new rectangular ams OSRAM 2mm2 chip, the LEDs produce very high luminous output – the KT CULPM1.13 True Green version is reckoned to be the brightest 520nm product in its class (1000lm at 6A), while the KT CULPM1.23 Red has a maximum output power of 650lm at 6A and the KB CULPM1.14 Blue has a maximum output power of 7200mW at 8A. The existing KW CULPM1.TG White version emits 1700lm at 10A.
Because of their thermal dissipation and small, flat package, the OSTAR Projection Compact LEDs can be packed very closely together in high-power luminaire designs. The thermal resistance is just 1.4K/W, while the 4040 package has dimensions of 4.0mm x 4.0mm x 0.75mm. The LEDs’ low profile enables lighting equipment and vision system manufacturers to reduce the size of their products without compromising brightness and performance.
Compared with competing products with a domed primary lens, the flat package of the OSTAR Projection Compact LEDs makes them easy to couple into optics, giving considerable flexibility to optimize the optical performance of the products for individual applications. All the OSTAR Projection Compact LEDs share the same footprint, enabling easy exchanging of colors in variants of a single board design.
“The excellent current-carrying capability, low thermal resistance and low profile of the OSRAM OSTAR Projection Compact LEDs means that machine vision products and stage lighting equipment can produce an impressively powerful output in any color,” says marketing manager Winfried Schwedler. “These LEDs can also offer high value in projectors and in architectural lighting units such as wall washers.”
The OSTAR Projection Compact LEDs are available now in production volume.
