Color Mixing and Zoom Lenses

Color Mixing and Zoom Lenses
 
By positioning Khatod lenses onto the micro LEDs in Red, Green, Blue and White (RGBW) colors, a real perfect optical system providing an excellent color mixing is settled.

Such optical systems are suitable for lighting items at short distance, because the light beams they produce do not transmit either UV rays or heat. They are particularly fit for close lighting such as shop windows, museum showcases, works of art, architectural and artistic details, etc.
They are also recommended in the specific wall-washing lighting which requires a perfect uniform light beam.
In fact, they prevent even the smallest uniformity differences which may cause annoying visual effects. The RGBW Polychromatic Technology generates the light through a very precise and accurate process which guarantees the exact reproduction of the selected color.
Khatod Color Mixing Optics for RGBW Systems are specifically designed for mixing four light beams of different colors in one beam, perfect and uniform, without any chromatic dispersion. Multi-chip sources used without specific secondary optics for RGBW systems, often produce chromatic shades caused by four separate lighting beams. This kind of lighting without using the proper lenses generates annoying chromatic effects, highly visible behind the lighted item.
On the contrary the use of Khatod specific optics guarantees an excellent colour mixing by creating one uniform beam, chromatically perfect. Khatod’s customers can always rely on our engineering and designing capabilities to create the most innovative products absolutely responding to the ever evolving requests of the optoelectronic technological progress.

Khatod, your best support in the growing requirements of the Solid State Lighting Market.

Color Mixing Lenses for RGBW Solutions

Single Color and Color Mix Appearance
The following figure shows the color appearance when all the LED chips are driven with same current, separately and simultaneously.
Viewing angles of single color and full color are almost identical, and the relative variation is smaller than those resulting from optical manufacturing and LED’s parameters dispersion.

AUTOFOCUS LENSES - Color Mixing - Zoom with MLA

AUTOFOCUS LENSES - Color Mixing - Zoom with MLA

Full range of Color Mixing Optics Equipped with Moving Lenslet Array (MLA) 45mm diameter; beam angles from 11° to 45°. Can be equipped with a special MLA to be mounted on top of the lens allowing ZOOM and AUTOFOCUS applications. By sliding it on top of the lens you can vary the beam angles in a range from 11° to 45° by preserving a perfect color mixing and a high optical efficiency over 90% in the full range of the beam angles. The MLA and the lens fit perfectly as they have the same diameter. The beam angles vary from the narrow confi guration when the device is in contact with the lens, to the wider configurations when the MLA is made sliding over the lens.
