dedolight® Technology
.

The Optical System
The original dedolight patent introduced a second lens which provides several advatages over traditional Fresnel systems.

Low Voltage Lamps
Using low voltage lamps offers several advantages compared to traditional light sources.

The Lenses
Four years of optical research and development led us to further improvements in professional lighting. The resulting patent introduces a relation computed double Aspherics² system.

The Mechanics
An additional patent introduced the added movement of the second lens in relation to the lamp and reflector all being controlled by one focusing knob. This technology was first used in the dedolight Series 400 as a triple zoom focus.

UV Radiation
UV radiation is produced by many light sources. UV – C, the shortest wavelength, is the most hazardous type of radiation, and although natural sunlight contains a great deal of UV – C, this is fortunately filtered out by the ozone layer. Using artificial daylight sources like metal halogen, we are also subject to dangerous levels of this type of UV. No metal halogen light source should ever be used for direct lighting of people or sensitive objects without some form of protection.
A degree of protection may be provided by additives to the glass during manufacture or by utilizing special UV absorbing glass. This type of filtering may produce a color shift and loss of light, and still won‘t entirely cut out UV.
We have been successful in developing a filter coating which effectively cuts UV – A, UV – B and UV – C radiation below 405 nm. This coating is deposited on the inner side of the front lens and does not affect the visible light, color rendition or transmission. The UV emission of our daylight sources (DLH400DT and DLH200DT) is approximately 1/20 th (5 %) the UV emission of comparable light sources.
On our 400/575 W and 200 W daylight soft lights we utilize a doted quartz glass tube which effectively lowers UV values giving significant advantages over similar light sources. Our Series 200 lamps are manufactured with a UV stop envelope which does not lower UV values beyond our coating, but may be regarded as a backup safety.
The UV content from halogen light sources is regarded as less harmful to people lighting but will still affect sensitive objects such as textiles, paintings and photographs. We offer an optional UV protection which is commonly used in museum lighting. Our special dichroic filter technology offers the lowest UV values in the professional lighting world.

The Imager Projection Attachment
Building highly perfected optics for dedolight light heads, allowed us to design imaging attachments with matching optics for unprecedented precision, quality of image and light/shadow shapes.
