Food and beverage processors are increasingly using UVC LEDs to disinfect surfaces and reduce the risk of foodborne illness. UVC LEDs inactivate harmful bacteria and viruses by damaging their DNA, preventing them from reproducing.

Specifies an f-stop value that allows you to intuitively increase/decrease the light's intensity when matching to a plate, or rendering large/tiny scenes without using hugh/miniscule Intensity Multiplier numbers. A value of 0.0 means the intensity does not change.

Yes, it depends on what you are going to use it for. But in my opinion, 365nm UV light is more powerful to detect fluorescence, identiy jade, etc.

Natural sources ofUV light

UVC LEDs are used in a variety of ways in hospital sanitization, including disinfecting medical devices and equipment, air and surface disinfection, and water purification.

This setting increases or decreases the intensity of the light in "stops" for your back-plate. Therefore, a value of one means "twice as bright", a value of two means "four times as bright" and so on. A value of -1 means "half as bright", a value of -2 means "quarter bright" and so on.

Some renderers use a different convention for how a domelight should wrap around the virtual world in the X axis. The Flip Horizontal option, as the name suggests, flips the domelight in the X axis to help match the look of a different renderer.

When enabled the dome light background will render with a solid alpha value of 1. If you need alpha for the background be certain to enable Replace Alpha Channel and set the Alpha value appropriately.

When enabled this allows you to over-ride the texture alpha values, which may be necessary if they are either non-existent or not correct.

In the example below you can see how in the render aspect ratio version all of the back-plate texture is squeezed into the frame horizontally.

This is a percentage value, so 100 results in the full saturation of the loaded Texture being used. Since this Saturation only applies to the loaded Texture, you can still use the Color setting of the light.

In the examples below the grey floor object has been rendered as a matte object to better demonstrate the uses of a back-plate. In the first image the you can see only the dome map as the background however once the back-plate is enabled it completely replaces it. Note that you can still see the reflections of the dome map in the reflective ball, not reflections of the back-plate.

The closer your tint color is to white the less affected your light color will be. For a mild color tint be sure to use a desaturated color, a fully saturated color can fully tint all the colors in the scene as pictured below in the saturated green example.

You can use this color not only for the light, but also to use as a visible background color, if the Background option is active. If you decide to load a Texture this color will get multiplied with the texture.

Light parameters controllable by a light shader include the lights Color settings, Decay, Shadow options and Attenuation.

You can use this value to shift the colors used in the loaded texture. If you just like to color the loaded Texture, you can use the Color instead.

Dome lights cannot be combined with environment shaders. If the scene or any material uses environment shaders, the dome light will override them.

Note: Other wavelength LED’s are also available including 310 nm, 365 nm and 405 nm (UVA and UVB). Minimum buy and lead times will vary, but typically start at 25 pcs and 2-3 weeks.  Please contact customer service with your wavelength and quantity to receive pricing and lead times.

UVC LEDs are effective against E. coli, Salmonella, Listeria, Legionella, Staphylococcus aureus, COVID-19, influenza, norovirus, among others.

Our UVC LEDs are rated as 275 nm (270 - 280 nm) wavelength and they are available in few different power levels and styles. Choose from single, chip-on-board, strip, to complete light source module using the specification chart below.  Volume pricing is available for all items noted in the chart below. Longer strip lengths with higher outputs are also available. Lead time will vary by product ranging from 1-6 weeks depending on the item selected and volume required.

Perhaps the most important element of a dome light is its texture map. Ideally, HDR textures in OpenEXR format should be used because they can capture a wide range of intensities. Such HDR can textures can either be obtained in the web or an application (like "HDR light studio") can be used to author them.

Typically, for environment textures, the alpha value should always be 0.0, if you plan on compositing environment layers.

This setting sets the color saturation of the back-plate. Values below 100 are desaturated and values above 100 are oversaturated.

UV lightsources in home

Yes, UVC LEDs can be used for mold and mildew control in residential and commercial settings by killing mold and mildew spores, preventing the growth of these harmful fungi.

UVC LEDs are very effective for surface sterilization, with studies showing that they can kill up to 99.99% of bacteria and viruses on surfaces.

Below are a couple of shots demonstrating this. The first image of each pair is the dome light map and the second is the final rendered result.

UVC LEDs are a more sustainable and energy-efficient alternative to traditional UV lamps for disinfection applications. They consume less power, produce less heat, and do not emit harmful mercury vapor or ozone.

UVC LEDs belong to the category of light-emitting diodes that produce ultraviolet light within the UVC wavelength band (200-280 nanometers). The emitted UVC light is recognized for its capacity to inactivate bacteria, viruses, and various other microorganisms.

Visiblelight source

In a sense, the domelight's texture features behave like area lights: large area lights produce soft shadows while small area lights produce sharper shadows.

The Redshift domelight is an infinite, texture-mapped area light. Using HDR images you can achieve high-quality lighting results that would otherwise require several lights. Since a single dome light can reproduce the lighting of several distant lights, it can help with performance, too. Furthermore, given that the HDR image can originate from a real-world environment, the dome light is an important tool to match the lighting of cg elements with live-action elements.

Yes, UVC LEDs can be used for water purification to inactivate bacteria, viruses, and other microorganisms that can cause waterborne diseases.

Many settings of the Redshift light object can also be set through the material node system. Using this button will create a new Redshift Shader Graph material and connect it to this light.

LED's have been increasingly used in applications where UV lamps (mercury, xenon, amalgam, excimer) have operated for decades.  Improvements in UV-LED flux density, stability and life hours have made UV LEDs a viable solution for replacing traditional UV light sources such as mercury arc lamps, arch lamps, hot and cold cathode lamps, and grid lamps.  UV LEDs are more environmentally friendly as they do not contain harmful mercury, do not produce ozone, and consume less energy.  Use of UV-C LEDs is rapidly growing in applications such as germicidal (UVGI) for air, surface and water purification.

If a Shader Graph material has been asigned to the light, you can open the Redshift Shader Graph by using this button and edit the shader directly there.

For the next example, the boxes were made bigger. The more brightness a dome light map contains, the brighter the lighting. For this reason the 'tint' parameter was reduced to (2, 2, 2). As it can be seen on the final render, larger boxes create softer lighting.

The dome light map contains only two small boxes. This is not an HDR map and, because the boxes are small, they can produce very dark lighting results by default. To fix this issue, the dome light's 'tint' parameter was set to (60, 60, 60). Because of the small bright boxes, the shadows on the final render are fairly sharp.

International Light Technologies offers UVC LEDs for a variety of applications and uses. Our UV LEDs are effective against eliminating harmful bacteria, fungi, and viruses such as COVID-19. Below are some of the most common applications our products can be used in:

You can find these commands in a menu to the right of the Type menu. You can use them to add a Target expression tag to the light. By linking an object to that tag you can aim the z axis of the light to that object. Using the Add Target Tag and Null command creates an additional Null object and uses that as the Target Object with the Target expression tag.
