RGB LED features superior heat dissipation

Lumex Inc. announces the global launch of the through-hole QuasarBrite 4-Leaded RGB LED. With a 120° viewing angle, the new LED is suited for applications that require high intensity light in spatially restricted spaces. Additionally, the 4-Leaded RGB LED boasts a lead frame design that provides superior heat dissipation and provides opportunities for cost and space savings.

The QuasarBrite 4-Leaded RGB LED provides excellent visual performance. Whereas a traditional through-hole LED features a viewing angle of 30° to 60°, the QuasarBrite LED has a viewing angle of 120°. The RGB format combined with this extended viewing angle provides consistent, well-matched visual performance and even view angle throughout the display.

The RGB LED features an enhanced thermal design lead frame, which allows for superior heat dissipation and therefore longer life expectancy. The off-the-board design also provides enhanced convection with air freely passing on all sides of the epoxy for more efficient cooling.

These features make the QuasarBrite LED suitable for applications that require a matrix of high intensity output with a wide viewing angle including:

  • High output signage (close proximity), such as airport, retail, and hospitality signage
  • General lighting, including decorative lighting and indicator lighting
  • Gaming, including decorative and indicator lighting throughout gaming machines

The QuasarBrite LED also provides several opportunities for cost and space savings. The use of a single 4-Leaded RGB LED can result in up to a 30% cost savings as well as a 70% space savings compared to the use of individual red, green, and blue packages. Replacing three parts with a single part number also simplifies ordering and maintenance processes.

The RoHS compliant 4-Leaded RGB LEDs (part number SSL-LX503SIUPGUSBC) contain three individual dies in red (635 nm), green (520 nm), and blue (470 nm). Samples of these devices are available from stock, with production quantities in six to eight weeks.
