Lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the beam

Lenses in standalone versions or lens assemblies in many sizes and with different light patterns are bringing high quality to LED optics of a complete light module. The main goal is to achieve better beam control by reduction of glare caused by the ”point source” and a wide angle intensity distribution. It offers now the possibilities to make more uniform light with different beams and cutoffs. This is needed for illumination standards in many applications such as street lights, aviation lights, medical lights and others. We are able to offer you selection of lenses upon outcome beam picture. Lenses also give a finished look and a protection for the LED. With it you can collect all the light from the light source and make it a narrower more intense beam such as 40° which is by the way a usual beam angle for halogen replacement. We are offering thru our lines large variety of lenses for almost all high power LED models in stand-alone versions and and lens assemblies in many sizes and with different light patterns: Asymmetric lenses for many high power LEDs optimized light distribution and high efficiency and high quality materials for outdoor use, lenses for multiple LEDs large variety of lenses for most LED types in different arrays and clusters as well as standard lenses for up to 13 LED arrays. 


Reflector is an optical part that regulates luminous flux from the light source by reflection from reflector material - a mirror reflection, a diffuse reflection, and a mixed reflection

Reflectors are basically divided into two groups: first group includes conic reflectors of four basic geometries – elliptical, zonal, hyperbolic, and parabolic; second group includes non-conic reflectors, such as square or asymmetric ones of the same basic geometries of reflection surfaces. Single reflectors used in spots and wall washes produce a beam with an even output and a sharp cut-off, however, it is not possible to produce narrow-angle beams. When the LED is placed exactly at the focus of a parabolic reflector, there will be a bright spot in the center of the emitted beam. So in many cases it will make more sense to mount the LED light source off the reflector focus. A very efficient solution is TIR (Total Internal Reflector) optics, which combine a reflector with a lens to form a compact and robust light source. Spot- and track-light designs particularly benefit from the TIR optics’ efficiency of about 85%. Such a system is fixed focus and cannot produce very narrow beams. Designers should ensure that the light source is well-centered to avoid the appearance of dark spots in the image.


Diffuser directs the light by diffuse-scattering through its material

Based on diffusion mechanism diffusers are divided into the following types: Opal, Gaussian, and Prismatic diffuser. For example opal glass and plastic, etched glass, fabric and paper shades act as diffusers.


A collimator is a optical device that narrows the beam

The highly efficient product line of collimators from LEDnLIGHT Solution by Gaggione provides excellent color mixing properties bringing several benefits like light output efficiency up to 90%, sharp cut off with very narrow beam available, additional versions offer range of angles including elliptical planned and ZOOM alternative with secondary lens. They are perfect to address stage lighting, entertainment lighting, architectural lighting applications and other applications looking for power and intensity with excellent cut-off and light efficiencies. A perfect parabolic mirror will bring parallel rays to a focus at a single point. Conversely, a point source at the focus of a parabolic mirror will produce a beam of collimated light creating a Collimator. Since the source needs to be small, such an optical system cannot produce much optical power. Spherical mirrors are easier to make than parabolic mirrors and they are often used to produce approximately collimated light. Many types of lenses can also produce collimated light from point-like sources.
