Ultraviolet lamps designed for tanning beds typically emit UVA radiation, sometimes with a small percentage of UVB. Tanning lamp manufacturers like LightSources offer various innovative lamp designs and proprietary solutions.

UV light was first discovered by German physicist Johann Ritter in 1801 when he discovered that invisible light rays darkened paper soaked in silver chloride faster than visible light.

Far UVC lamps are becoming more popular as they are designed to emit wavelengths close to 222nm, which is found to provide the similar germicidal efficacy to 254 nm lamps while being safe to use in occupied spaces.

The history of UV light providing therapeutic effects dates back to the early 1900s, with UVA and UVB lamps providing effective treatment to a variety of skin conditions. Specific medical phototherapy lamps must be used for effective treatment and should be prescribed by a physician and used under a doctor’s care.

You can see this figure when you check the spec list of a video light. For example, the COLBOR CL220 LED constant light for photography offers 105000 lux of 5600K at 1 meter. It is 25% brighter than the similar fixtures on the market.In the case of illumination company, both illumination and illuminance are meant to show the same property of light. For instance, “illumination” is used for COLBOR video lights to indicate the illuminance. Here are the figures:

UVC germicidal lamps are also used in many surface disinfection applications to prevent the presence or buildup of harmful microorganisms on surfaces. UV surface disinfection lamps are used in hospitals and medical applications, restaurants, commercial kitchens, and residential products.

Artificial sources ofUV light

UV lamps are used in a variety of industrial processes that require curing various coatings, varnishes, lacquers, adhesives, and inks. UV curing provides many benefits to manufacturers with faster curing than air-dried processes and a higher level of quality. UV curing is used in many applications, such as automotive, electrical, optical, and other industrial applications.  LightSources offers various UV curing lamps, including medium pressure, high pressure, and amalgam curing lamps.

Illumination can render emotions and atmosphere. Understanding what does illumination mean can help photographers to capture many different types of emotions in photos. The good illumination produced by well-positioned and good-quality light will change the photography.

UVC lamps provide a highly effective, cost-efficient, and safe alternative to chemical water treatment. UVC lamps are found in many water disinfection systems, such as wastewater treatment for drinking water and industrial water, life sciences and aquaculture, pool and spa applications, and other water treatment applications.

Visiblelight source

Ultraviolet (UV) light means “beyond violet,” as violet is the highest frequency of light visible to the human eye. The electromagnetic spectrum of light that the human eye can detect is in the range of 380 to 700 nanometers (nm). UV lighting has a shorter wavelength and a higher frequency than visible violet light.

Upper room UVGI systems are designed to disinfect air above occupied spaces in wall or ceiling-mounted UVGI fixtures.  UVC lamps in HVAC systems also disinfect air as it passes through furnaces and AC units to remove harmful airborne contaminants and protect equipment against the buildup of mold and fungi.

What is illumination of light? As aforementioned, illumination is the property and effect of light in an observable form, presenting the use of light sources. By contrast, illuminance measures how much luminous flux is spread over a given area. Luminous flux, which is measured in the unit of lumens, can been considered as the measurement of how much visible light present in total while the illuminance as the measurement of illumination intensity on the surface.

Each category of UV lighting has very useful purposes for many industries and applications. UVA and UVB light are common in many medical phototherapy lamps. UVC light has been known for over a century to possess highly effective disinfection properties, particularly at 254 nm.

In photography, light is of the greatest importance, for the reason that illumination is the result from it. When taking pictures without light, it will only creates a photograph of complete blackness. However, with lighting, everything taken place will be illuminated. It is now then the photograph will actually present something. Therefore, the illumination given by light and the light itself are required for both human eye and the camera. To further define illumination, the illumination of scenes to be taken shots is called photographic lighting. Unlike photograph, which only records structure of color, light and shade, lighting focuses wholly on having control over the image. Illumination aims at the accurate reproduction of the scene, while considering the control of brightness, color and direction. Light and illumination are the fundamental features of photography. The genre of lighting, also the type of illumination that are being used is one of the most essential factors of photo when concerning photography. In photography, light means how the light source - natural or artificial - is placed in accordance with the subject. Both the position and the quality can be the causes affecting tone, atmosphere, mood as well as brightness and darkness. When making photography of portrait, still life or landscape, it is up to the characteristics of the subject, and the expected way of portraying in the photos that which lighting to choose, also how much illumination to get. Let’s take soft and hard lights as an example. The hard light puts emphasis on angles and rough surface while the soft one smooths these features.

LightSources is an industry-leading global supplier of UV lighting solutions and UV germicidal lamps used in these processes and other germicidal applications.

As for the word “photography”, it is derived from the Greek words - phos and graphis. In Greek, phos means light while graphis means drawing. When the two words combined as “photography”, it can be defined as “drawing with light”. The significance of photography is about capturing and recording light in the form of paper or digital format.

UV lamps designed to emit UVC radiation in the range of 254 nm are used in many germicidal applications, such as UV air purification systems, UV water disinfection, and UV disinfection of surfaces.

UVC lamps have been used for decades to disinfect and remove harmful contaminants from the air, including dust mites, mold spores, viruses, bacteria, fungi, and other harmful airborne microorganisms. UV C air disinfection has a long history of improving indoor air quality and preventing various airborne diseases, as reported by the National Library of Medicine, The History of Ultraviolet Germicidal Irradiation for Air Disinfection.

What does illumination means? When a light source is poured onto the objects, they reflect light that can been perceived by human eyes. What illumination means is the act of using this light source. Illumination is commonly seen, for example lighting in rooms or task lighting on desks.
