The through-hole QuasarBrite 4-Leaded RGB LED from Lumex features a 120° viewing angle and is targeted for applications that require high intensity light in spatially restricted spaces. The new LED has an innovative lead frame design that provides superior heat dissipation and provides opportunities for cost and real estate savings.
A traditional through-hole LED has a viewing angle of 30° to 60°, while the QuasarBrite 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 enhanced thermal design lead frame of the new QuasarBrite 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. The QuasarBrite also has superior moisture resistance when compared to typical surface-mount devices.
The QuasarBrite 4-Leaded RGB LED is designed for applications that require a matrix of high intensity output with a wide viewing angle, such as close proximity high output signage (airport, retail and hospitality signage); general lighting (decorative lighting, indicator lighting); and gaming (decorative and indicator lighting throughout gaming machines).
The new LED provides several opportunities for cost and real estate savings. The use of a single 4-Leaded RGB LED can result in up to a 30 percent cost savings as well as a 70 percent real estate 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 (635nm), green (520nm) and blue (470nm). Samples of these devices are available from stock, with production quantities in 6-8 weeks. Pricing is dependent on quantity ordered, and is less than one dollar per unit in production quantities.
