45mm collimators for CoBs in PMMA and PC

by admin

Gaggione has produced a household of 45mm collimators for cob (chip-on-board) leds.

VEGA45V produces a 50° beam

Known as Vega, they observe on from its 45mm LLC59 colimators.

Like LLC59, Vega collimators will probably be obtainable in PMMA plastic, but additionally in polycarbonate.

There are eight beam choices, a few of them suitable with color mixing or tunable white use.

Compatibility is claimed to be full for CoBs as much as 6mm in diameter, then “partial” from there to 9mm.

They’re:

  • VEGA45U extremely slim, 8.5° beam
  • VEGA45UF extremely slim frosted, 9° beam
  • VEGA45N slim, 9° beam
  • VEGA45C color, 11° beam
  • VEGA45M medium, 25° beam
  • VEGA45W vast, 34° beam
  • VEGA45V very giant, 50° beam
  • VEGA45E  elliptical, 9-33° beam

From the ‘color’ model downwards, all are appropriate for tuneable-white, RGBW and dim-to-warm purposes. Beam angles are FWHM (full width half max, so 34° is ±17°) measured with PMMA collimators utilizing a 6mm emitter Citizen CLU7S3. The very giant beam sort is within the pipeline.

Taking the ultra-narrow PMMA VEGA45U (proper) for example, the info sheet supplies these beam angles:

Citizen

CLU7S3 Cree

CXB1310 Cree

CXB1520 Luminus

CXM_3 FWHM 8.6° 12.7 17.9 8.1 FWTM 14.7° 21.8 30.8 13.4 Efficacy 35.2cd/lm 14.6 6.1 40.5

And the web site reveals the polycarbonate VEGA45U delivering 9.1° FWHM from a CLU7S3.
