FULLY SEALABLE SPUTNIK-Z lenses for SSC P3, P4
- Use with Seoul Semiconductor P3 and P4 series of white and monochromate LEDs
- Lens material optical grade PMMA with high UV and temperature resistance
(105°C/220°F)
- High optical efficiency, up to 90%
- NEW smooth spot and oval versions with improved efficiency and color uniformity also
compatible with the new P4 package
- No lens holder. Fastening to heat sink with a PU foam adhesive tape of automotive
grade
- We advise customer to ensure the suitability and sufficiency of the bond in the end
product. For example, mechanical stress, vibration and holes on the surface of the
circuit boar weaken the strength of the tape.
- Please check fastening details from this link:
(http://www.ledil.com/datasheets/DataSheet_TAPE.pdf)
- Lens foot can be potted with resin without loosing anything in optical efficiency (fully
sealed construction possible)
-
Diameter 26 mm (approximately 1”)
-
Easy build of a complete luminaire using SPUTNIK, P3 or P4 and heat sink
- Mechanical CAD models available upon request
-
All lens types have the same outer dimensions, which allow a cross use of them in the
same lighting fixture
LENS TYPES
NAME ORDERING CODE FWHM Angle
Sputnik-Z smooth spot CA10321_Sputnik-Z-SS ±5°
Sputnik-Z medium CA10249_Sputnik-Z-M ±13°
Sputnik-Z oval CA10322_Sputnik-Z-O ±7° x ±18°
Sputnik-Z wide CA10241_Sputnik-Z-W ±32°
SMOOTH SPOT lens is a pure collimator lens with light mixing properties. It smoothens the
beam pattern and makes a uniform color distribution over the whole beam angle. Light
intensity is lower than for the REAL SPOT lens. SMOOTH SPOT lens is recommended for
white light applications, where pleasant, high-quality illumination is wished.
OVAL lens is optimal for cases where a narrow stripe of light is wished. If a wider vertical
distribution is needed, please consider LEDIL SSS-O with wider vertical distribution and a
color mixing structure.
