Compact LED for safety
20 April 2010
One of the most compact and energy efficient 3W miniature high power LEDs has been launched.
Avago Technologies’ 3W high power LED emitters comes in an ultra-small package for SSL applications.
It is for use in a range applications and measures 5mm x 4mm x 1.85mm. The 3W ASMT-Jx32 is packaged in a 6-leaded small outline package (SOP) and is capable of being driven to up to 700mA to provide high flux output performance.
Additionally, this compact LED emitter features a wide viewing angle and long life reliability. By delivering a high flux output of a minimum of 100 lumens (lm) at 350mA driving current, the 3W LED emitter is ideal for safety exit and emergency lighting, portable lighting applications, street lighting, residential lighting, task lighting, and other solid-state lighting applications requiring high flux output performance.
The ASMT-Jx32 provides a wide viewing angle of 140° to meet the needs of designers who require good colour uniformity. The ASMT-Jx32 features a maximum allowable junction temperature of 135°C to provide greater design flexibility to lighting designers. This LED has high Electrostatic Discharge (ESD) resistance of 16 kV, which makes it insensitive to ESD. As a result, special ESD protection equipment is not required to handle the part during installation. Furthermore, this 3W LED is compatible with standard SMT reflow soldering processes.
This LED is encapsulated in a heat and UV resistant silicone material and also features a low thermal resistance of 9°C per Watt due to its heat dissipation capability. In addition, the electrically neutral heat pad allows arrays to be connected on a common heat sink; simplifying thermal design.
