Everlight Extends JU Series of COB LEDs

Everlight Electronics Co. Ltd., a leading player in the global LED industry, has expanded its high performance JU series of chip-on-board (COB) LEDs to include 7, 10 and 15 W types in addition to the existing 4W version. COB LEDs are especially suited for directional applications that require a powerful single light source for effective illumination such as GU, MR and PAR retrofits, downlights and candelabras.

The JU series now consists of four JU1215 (15x12x1.6mm) and one JU2024 (20x24x1.6mm) type/s with powers ranging from 4 watts to 15 watts. All types provide an efficacy of 110lm/W or more at 3000K CCT, a CRI of >80Ra and 25°C substrate temperature, and are available in versions ranging from ANSI bin 2,700 K to 6,500 K. The JU series also offers 3 step (McAdam) options for advanced utilization.

JU COB LEDs are multi-chip solutions that are directly applied to the board without housing, for efficient thermal dissipation. Their ceramic substrate base allows for thermal resistances of below 2°C/W, with the largest wattage COB measuring around 0.8C°/W. Low thermal resistance and superior heat dissipation ensure high reliability and increase the LEDs’ service life.

Each COB has its unique features with carefully calculated chip configurations for optimal lumens per dollar of >400lm/$ and optically compact light emission surfaces (LES) for effective pairing with secondary optics.

Additional JU COB options such as Color Choice®, high voltages from 45 to 250V for different regions and applications, and high CRI (>90Ra) are available to meet customers' specific needs. All JU COBs have completed LM80 lumen maintenance testing and are offered with a complete line of accessories such as standardized holders, appropriate reflectors and more.

The future product roadmap of the JU family provides for additional higher power members as 25W / 35W / 50W for track light, down light or low bay applications by Q4/2013. Meanwhile, 4W / 8W / 13W / 17W / 26W MCPCB 120lm/W COB are coming out for wider options.

Mass production has already started and samples are available upon request.
