Product model: KULLEN
Product name: Total Internal Reflection Fresnel Lens (T.I.R Fresnel Lens)
Product category: Fresnel lens
Total Internal Reflection Fresnel lens (T.I.R Fresnel lens in short) has the characteristics of ultra-short focal length, high transmittance, high efficiency concentrating, uniform output, and good spot transition.
How to use: Place the LED at the focus position of the centerline of the lens, and the position of the light source and the lens is fixed.The beam angle will widen and narrow with the LES of LED.Multiple light sources and lens units can be used to form a high-power matrix, and the beam angle is almost the same as that output by a single group.
Applications: flood lights, stadium lights, exhibition lights, audience lights, spotlights, downlights, high bay lights, beam lights, outdoor searchlights, flashlights, etc.
Light pattern: Beam angle changes with the LES of LED
