The concept of reflected light is as old as image creation itself. In the past it used to support other lighting situations, now it can possibly be a predominant lighting practice. Versatile creative and with some unprecedented advantages.
The concept of creating the illusion of natural light deriving from a very far distance, even in the smallest most confined space. dedolight Lightstream practice can also enhance the sensation of space and depth, creating a three-dimensional illusion. It can offer a very different character compared to other kinds of lighting. Now we can talk about different light sources starting with sunlight and other traditional light sources and we will also explain different reflecting tools.
The biggest lighting instrument that we provide at the moment is the parabolic parallel beam light PB70. Such lights are not new; they have existed for a long time in different versions in the professional lighting and entertainment industry, for special effects as well as for military applications.
For our purpose we want a parallel or near parallel light that is clean and homogenous as possible. This can be achieved with a parabolic reflector which on its own is not perfectly suitable, it needs a little bit of help. This will best work with a point light source so therefore we use a metal halide HMI light source.
We developed a special light source modified for good homogeneous color spectrum maintained through the entire lifetime and modified to contribute the most homogeneous light distribution and the smoothest near parallel beam within the parabolic reflector.
Several aspects of this may be noteworthy: the virtual light source with such a near parallel beam the light does not derive anymore from the light fixture, the instrument, it is to be seen as a virtual light source from way behind the fixture.
How do we define this?
We elongate the outer rays of the beam backwards until they cross and that is where the virtual light source is active. With the PB70 this is between 6 and 20 meters behind the instrument. This enhances the distance from the effective light source to the object and thus it diminishes all the ill effects of the square law - when our actors move the change of intensity is less noticeable than we've known before. This inverse square law, as you know, is defined double the distance one quarter of the light. Now we know different ways to overcome these deficiencies but dedolight Lightstream with the PB70 light is also a very effective tool in this matter.
