San Jose, Calif. Avago Technologies has released a low-profile, 3-watt high-power white light emitting diode (LED) emitter for a variety of solid-state lighting applications. The ASMT-MW20 surface-mount power LED emitter offers a combination of high brightness, long life and compact size.
The ASMT-MW20 SMT LED emitter can be driven to a high current of 700 mA to deliver up to 160 lumens of light output, which is said to be 40 percent brighter than competing LED emitters to offer the industry's best lumens per watt efficiency. The combination of high drive current capabilities and high brightness make the power LED emitters suitable for solid-state lighting applications that require a high-output light source where space is limited.
Typical applications include lighting for machine vision equipment, billboard and sign backlighting, street lights, reading and track lights, accent lighting, architectural facade lighting, and torch lights and miner headlights.
The ASMT-MW20 Power LEDs provide two advantages in the production environment they can be easily soldered using conventional surface-mount techniques to minimize production costs, and the package is qualified to a Joint Electronic Device Engineering Council (JEDEC) moisture sensitive level (MSL) rating of 2a. This rating means that the LEDs can be kept in the open air (30°C, 60 percent relative humidity) for up to four weeks after being removed from its sealed package without the need to remove absorbed moisture.
In addition, with an exposed pad design at the back of the package, the ASMT-MW20 power LEDs incorporates InGaN technology to offer low thermal resistance which allows it to efficiently transfer heat from the package to the motherboard for long-term device reliability. Other features include a wide viewing angle of 110 degrees and heat and UV resistant silicone encapsulation. The operating temperature is -30° to 85°C. The devices are lead free and RoHS compliant.
Pricing: In the $6 range for small quantities.
Availability: Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners.
