MOON is an innovative solution for very small form factor luminaires requiring both a zoom and a colour mixing function. MOON is a silicone light guide and projection lens based on our experience in stage lighting and entertainment.
It was developed in collaboration with one of our most important customers in the stage lighting market. Since the colors or white colour temperature are mixed using multiple internal reflections inside a silicone rod, the homogeneity of the colour is perfect, even on the most difficult colors. This is the best possible solution for high-end luminaires with a diameter of less than 20 mm.
Please note that as a partner product, it will not be available for all applications. Do not hesitate to contact your sales representative for more information.
MOON being a very innovative and atypical optical solution, you will need some guidelines to prototype and integrate it. We have published a MOON Application Note to help you in this process. This application note covers the main questions you will be facing while designing you upcoming fixture. It covers mechanical integration, qualification of beam angles and LED selection option.
A LED injects light on the base of the light guide. Multiple reflections among the light guide length ensure a perfect light homogeneity on the output surface. The image of the output surface is projected by the lens to create the beam.

As a light guide technology based system, MOON consists of two references :
MOON G : Assembled part containing silicone light guide and two-parts holder
MOON is recommended to be integrated with high power flat top LED. As the light guide technology is capable of color/chip emission mixing, single or multi chip, white or RGBW references can be used.
The input part of the light guide has been designed to fit with up to total 4 mm² LES. Using bigger LES might impact efficacy as a significant part of the light will not be collected by the light guide. To ensure the best possible light collection in the light guide, a distance of 0.1 mm is recommended between the LED and the light guide input. The MOON G holder has been designed to fit LED presenting a 1.3 mm thickness thus presenting a 1.4 mm difference between the PCB surface and the light guide input. When using a LED with a lower thickness, it is recommended to create routed areas on the PCB surface to compensate the difference.
MOON beam angle will vary while adjusting distance between MOON G light guide output and MOON
L lens input. This range has to be kept between 1.95 mm (wide beam) and 8.45 mm (narrow beam).
1.95mm corresponds to MOON G and MOON L in mechanical contact.
8.45mm corresponds to a 6.5 mm distance between the top of MOON G and bottom of MOON L.
