The Luxeon V2 LEDs use chip-scale package (CSP) technology to implement a compact optical source with tight beam control and high luminous efficacy, even at high drive current. Housed in a standard 3.5×3.5mm (3535) package, the emitter consists of an InGaN LED chip mounted on a ceramic substrate with low thermal resistance, which connects the die to a thermal pad to simplify thermal design. The ceramic substrate is overmoulded with a silicone dome. Each emitter includes a transient voltage suppressor (TVS) to protect against electrostatic discharge (ESD). With a drive current of 700 mA, a Luxeon V2 produces typical luminous flux of 310 to 315lm. Increasing the drive current to 2A boosts the output to around 760lm, at 123 lm/W luminous efficacy. Maximum drive current is 2.4 mA. The devices are now available from RS in the EMEA and Asia Pacific regions in packs of 10 or on reels of 2500.
