Optical lens

Low-angle ring lights have horizontally mounted high-powered LEDs that bounce light off a light guide creating uniform vertical light. They come in white, red, green, blue, and IR choices.

See the small protective dome above the diode? This is called the primary optic and helps protect and shape the output of small LED diodes. The light from the LED's primary optics is still too broad for most applications and too weak to illuminate only certain surfaces. Therefore, most LED lamps use secondary optics (lenses, reflectors, TIR optics, etc.) to capture all the light from the LED and increase its intensity. The most common LED lens is the convex lens that is placed around the LED. However, as technology advances, other types of lenses are also becoming more common. There are square lenses, high dome lenses, medium dome lenses and flat lenses. Each with its own light distribution and mounting over the LED diode.

Lens andlightphotography

An important part of LED lighting is the LED lens. As you probably know from cameras, the lens is sometimes more important than the optical source itself. With LED lighting, you can practically see the same thing. The lens determines how the emitted light is distributed. In other words, it determines the optics of the light. light pattern. Several factors are very important here. The convexity of the lens, the surface area and, of course, the thickness of the glass. The lens in combination with the reflector and the emitted light ensure the distribution and intensity of the light beam.

Coaxial lights provide uniform diffuse light from the same axis as the camera. Compared to bar lights, these lights reduce the impact of surface unevenness. They come in white, red, green, blue, and IR choices.

Standard ring lights illuminate the workpiece with direct light from an angle concentrating toward the center. They come in white, red, green, blue, and IR choices.

Uniform ring lights have vertically arranged LEDs transmitting light through a special light guide to produce highly uniform light. They come in white, red, green, blue, and IR choices.

Dome lights provide even light from a dome-shaped reflective panel flowing through a diffuser.  Even if the distance to the workpiece changes, there is little change in the uniform region. They come in white, red, green, blue, and IR choices.

Bar lights create direct light suitable for large workpieces. They come in various lengths, either 22mm or 37mm widths, and offer white, red, green, blue, and some IR choices.

Our online products represent only a fraction of the available lighting. All lights are available in additional sizes and spectrums.

Flat dome lights recreate the effect of a dome light from a low-profile case design. In addition, the light is uniform, shadowless, and can be coaxial with the camera. They come in white, red, green, blue, and IR choices.

De bollere lenzen bij LED’s, zorgen vaak voor een evenredig verdeelde lichtstraal. Ligt de bolling van de lens vlak op de LED chip, dan kun je uitgaan van een vrij evenredig beeld. Is de bollig van de lens hoog en lang? Dan zul je zien dat de lichtstraal meer gefocust is op één specifiek punt. Je kunt hier dan spreken van een gefocust lichtbeeld. Ook de binnenzijde van de lens heeft effect op het uitgestraalde licht. Zo zie je bij een vierkante binnenkant (lage lens, vierkant) een andere lichtverdeling, dan die van de bolle binnenkant. Een voorbeeld van een lamp die gebruik maakt van een vierkante binnenkant gecombineerd met een bolle lens, is de Fish-eye equipped optimus series.

Since lenses can have different purposes, different materials are used. One of the most common materials is PMMA. By heating this material and using a sturdy mould, this clear, reflective material is easily moulded into the desired shape. When making LED lenses, this has some advantages. The material can also withstand any heat. If you want to equip a sturdy light source that radiates heat with a certain lens, it is handy that this lens does not deform over time and therefore loses the desired light image. Other materials that can be found are polycarbonate and glass. However, these are quite expensive to process in your lighting.

Choose from a selection of durable lamps and magnifiers that brighten up your desktop or workspaces with full-spectrum or fluorescent bulbs.

The answer to this is simple: No! A lamp is composed of multiple components that together determine the light pattern. Although the LED lens is crucial for this light pattern, it should always be considered in combination with a reflector or the upper glass. For example, with an LED work lamp, you can use different types of lenses for different applications. The same applies to LED taillights, where the lens, in combination with a distinct color, must emit light. For this reason, an LED lens is not good, bad, or better. Seek advice from specialists if you want to add LED lighting to your machinery.

In the same table you can also see that there are two models with a flat lens. This flat lens is found on both the inside and the outside. Because of this you can see that the light distribution is not or hardly affected by the present lens. You can therefore see this as a protection for the LED diode rather than an actual optically changing component.
