Lumileds launches LUXEON CSP HL1 LEDs in directional chip-scale packages for small, bright spotlights

Lumileds LLC of San Jose, CA, USA has launched the LUXEON CSP HL1 LED, supplied in compact, directional chip-scale packages that provide high lumen density in directed, narrow beams or in ultra-high-density arrays for indoor area lighting. The package size is 1.4mm x 1.4mm x 0.3mm, with two pads that attach directly to the PCB for ease of SMD assembly and reduced cost. The line is designed to set new records for shrinking the footprint of spotlights, wall grazing, wall washing and linear fixtures for architectural, high-impact retail, home and office lighting venues.

The LUXEON CSP HL1 consists of side-coated CSPs that emit 100% of their light from the surface and none from the sides, enabling very tight packing of packages together with no crosstalk and complete beam control (beam steering) using LEDs. The result is a very clear beam and what is claimed to be excellent color over angle, leading to outstanding punch (CBCP, center-beam candle power) and use of the industry’s smallest secondary optics. To achieve smart color tuning for human-centric lighting, fixture makers can combine CSPs of cool and warm color temperatures and use a simple control scheme.

“The combination of tiny source size, high lumen density and uniform color translates to spotlights with outstanding punch and color quality,” says product manager Alvin Yeoh.

The LUXEON CSP HL1 is available in correlated color temperatures (CCTs) from 2700K to 6500K with a color rendering index (CRI) of 80 or 90 minimum. Output is 104lm at 3000K and 80CRI when driven at 350mA or 190lm when driven at 700mA. Record-setting lumen density of 200lm/mm2 can be achieved. The wide variety of CCT/CRI combinations in the LUXEON CSP HL1 enables flexibility in fixture design, whether for color tuning, beam steering or designing a complete fixture portfolio around 80CRI and 90CRI options.
