Custom LED Optic Design – TIR lenses, Reflectors and Light Pipes

LED optics is critical as it helps pull light together, boost its strength towards the target, and achieve the required lighting objectives. With over 40+ years of designing LED optics, Light Engine is sophisticated in creating optical lenses for industrial, commercial, and household applications, including high-power LED street lights, specialized aquatic-used and pool lights, horticultural lights, and professional and general lighting. We make the ideal matching of primary optics, secondary optics, and the targeted application, aiming to optimize lighting efficiency.

Custom optics design for best illumination

Flexible LED strip light with total silicon TIR lens provides precise beam angles as requested. High CRI and lighting uniformity are applicable for different fixtures and lighting purposes.

Patented downlight with precise secondary reflector optics

Propriety and patented multi-faceted inward reflector of Array AR111 lamp generating uniform light patterns with homogenous color temperature, allowing better beam consistency with controlled glare and minimal light leakage.

Patented UFO lens for Vortex MR16 fixtures 

A multi-faceted TIR prism and a condensing lens collect 100% of the output light from the LED source. The central condensing lens has a lens array on the bottom for light-mixing and collimating the light. The tiny diamond-shaped facets arrayed outside the reflecting surface are precisely designed to light-mix and redistribute the light.

Freeform secondary optics of LED streetlights

A diamond-shaped multi-facets on the freeform surface for light-mixing generate a homogenous color temperature in the light pattern, both at the center and the edge, 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, maximizing the output efficiency. The lens has a wide light distribution with a beam angle of about 150° along the roadway.
