OPTICAL DESIGN

Virtual Filament for
LED Candle lamps

  • State of the art secondary optics technology provides an essential sparkling effect on crystal chandeliers

  • Ideal bulb to replace the traditional filament bulb as it has a wide range of light and output beam patterns with similar focal positions above the base

  • Optical design of the virtual filament outputs with near uniform intensity across a whole beam angle of 270° to 300°

Precise Secondary Reflector Optics for AR111

  • The basic principle of anti-glare is to hide the LED source inside the luminaire. The human eye can only see the light reflected by the reflector but cannot see the glare of the light source.

  • The optical principle of the AR111 is to reverse the LED source and point it to the reflector. The reflector redistributes the light into a precise beam angle, which forms a uniform light pattern. The human eyes cannot see the light source, only the reflected light

UFO (Vortex lens) for MR16 fixture

  • State-of-the-art multi-faceted total internal reflection secondary optics, generating very uniform light patterns with homogenous color temperatures.

  • A multi-faceted TIR prism and a condensing lens, which collect 100% of the output light from the LED source.

  • Tiny diamond-shaped facets arrayed outside of the reflecting surface are precisely designed for light-mixing and redistributing the light.

  • The central condensing lens has a lens array on the bottom for light-mixing and collimating the light.

Freeform secondary optics of LED streetlights

  • Adopts the diamond-shaped multi-facets on the freeform surface for light-mixing and to generates a homogenous color temperature in the light pattern. This means the color temperatures at the center and at the edge of the light pattern are the same, thus eliminating the yellow edge problems in regular LED streetlights.

  • The micro prism array on the bottom of the lens acts as a retro-reflector to recycle the stray light that slips back to the bottom of the lens, so output efficiency is maximized.

  • The lens has a wide light distribution along the roadway and a beam angle 2Θ is about 150°, so the light patterns of adjacent lamps can be overlapped.
