Issuing time:2023-02-23 10:10


TOPLITE specializes in innovative optical design, delivering leading, reliable, and competitive optical solutions for over a decade. With multiple patents in LED RGBW color mixing, high-efficiency light concentration, matrix modules, narrow-angle projection, and HD imaging, we aim to enhance your product’s market edge. Below are our core optical products:



1. Total Internal Reflection (TIR) Fresnel Lens

Patent: Invention Patent ZL201710661235.9

Key Advantages:

  • Ultra-Compact Design: Enables lightweight fixtures via short-focal-length high-concentration optics.

  • Dual-Mode Lighting: Supports white/colored LEDs for soft white or vibrant colored outputs.

  • Adaptive Optics: Electronic zoom & ambient control; switch between narrow-wide angles via LED source selection.

  • Thermal Efficiency: Spacious lens-source gap reduces heat buildup, compatible with high-power LEDs.


Design Principle:

Features a planar exit surface with a convex central area and annular sawtooth structures on the input side. Utilizes refraction + total internal reflection (TIR) to concentrate light: LEDs emit rays refracted to a reflective surface, undergo TIR, and exit through the planar lens. Each tooth structure achieves short-focal, high-intensity concentration with uniform light spots. Available in plastic/glass, supports multi-lens arrays and good color mixing.

Applications: Stage beam lights, effect lights, searchlights, wall washers, outdoor beam lights, flashlights, commercial downlights, flashlights, vehicle/ship lighting.



2. Matrix Optical System, Condensing System & Fly-Eye Lens

Patent: Invention Patent ZL201910006857.7

Key Advantages:

  • High-Density Optics: Smaller beam waist with higher light intensity enables compact & brighter fixtures.

  • Modular Flexibility: Separates LED sources from optics for easy upgrades/maintenance across 190~1,800W power ranges.


Design Innovation:

Introduces a non-coaxial multi-layer fly-eye lens concept. Two-layer lenses with staggered micro-lens arrays (different spacing) match LED matrix modules (19/37/61 LEDs) for customizable power/condensing needs. A dual-convex lens outside the fly-eye array forms a high-efficiency optical system with adjustable light parameters.

Applications: LED moving head beam lights, BSW hybrid moving head, gobo projectors, searchlights, outdoor long-range beam systems.



3. Cylindrical Polyhedron Matrix LED Light Source

Patent: Utility Model Patent ZL201520595979.1

Key Advantages:

  • Dual-Function Optics: Simultaneously achieves high-efficiency color mixing & concentration, eliminating color aberration and stray light for uniform, professional-grade lighting.

  • Thermal Optimization: Arrayed LED chips with spacing enhance heat dissipation, improving luminous efficiency and lifespan.


Structure:

Comprises an LED chip substrate, cylindrical light guide pillar array, and metal housing. Light from RGBW/monochrome chips refracts through the bottom of light guides, undergoes TIR for mixing, and exits through a seamless top emission plane. Reduces output angle from 120° (standard COB) to 38°, increasing intensity while maintaining planar emission.

Product Line: STONEHENGE

Applications: High-power imaging systems, wash spotlights, follow spots, searchlights, film projectors, and projection light sources.



4. Zoomable Optical Imaging System

Patent: Invention Patent ZL201910238295.9

Key Advantages:

  • Versatile Design: Linear zoom/fixed-focus functionality with diameter options (22~200mm, customizable).

  • Achromatic Clarity: Achromatic cemented lenses (positive-negative pairs) eliminate color fringing for HD imaging.

  • Cost-Effective: Modular lens groups enable multi-scenario reuse, reducing design/production costs.


Working Principle:

Consists of a pattern plate, first/second lens groups (cemented doublets). Moving lens groups along the optical axis adjusts focal length; single-group use enables fixed-focus. Mathematical ratios between system/element focal lengths ensure linear zoom within allowable angles.
