 The basics of stage lighting technology and industry development NEWS

    Since the stage production, stage lighting, the stage will become a component part. Stage lighting, in your outstanding vision, realism, aesthetic and performance of the four elements. After years of evolution. Gradually developed into a more complete and advanced lighting systems. The first boom period drama, in two thousand years ago in ancient Greece. At that time the theater is open or semi-open. Stage lighting is by the sky that's enormous "light" - the sun, we can only perform during the day. The night entertainment needs rest, vulnerable to weather and other open-air performances and drama development objective disadvantages to become a stage lighting must be addressed. 
    Show the success of lighting design, stage lighting is based on the appropriateness of the treatment as a symbol. Stage lighting to illuminate not only the actors, the audience to see facial expressions, posture and movement, more importantly, make full use of lighting technology, lighting operations and other means to mobilize to strengthen artistic effect, give the audience a feeling.

    Stage lighting is mainly by the combination of computer lights and other lighting effect produced is a film scene through different shapes, different color changes, a different perspective, horizontal, vertical angle changes and the speed of light speed, strobe speed, aperture size changes , focal length changes and overall performance. Then, in stage lighting techniques to understand before they need to master these basics:

    First, the visible light

    Just form of electromagnetic waves by electronic transmission of radiant energy. Electromagnetic radiation wavelength range is very wide, only 380 ~ 760nm wavelength in this part of radiation can cause light vision, known as visible light. Wave length in the 380nm light is ultraviolet, x-rays, γ-rays; longer than 760nm is infrared light, radio waves, they are light on the human eye does not produce visual, that is invisible. Therefore, the energy just kind of objective existence, and with people's subjective feelings are closely linked.

    Second, the color classification

    Colors can be divided into two major categories of non-color and color. Color refers to non-white, light gray, gray to dark gray, until the black is called white-black series. White is ideal for light reflection completely object, the reflection rate of 1; black is the ideal non-reflective object, the reflection rate of 0. Therefore, non-color white light black line represents the reflectivity of the object changes. We know that the light reflectivity and brightness is proportional to the white interior walls and ceilings can be higher brightness. Color is black and white series of a variety of other colors. Color has three properties: hue, lightness and saturation, as the three elements of color.

    Hue is the color of that showing. That is the name of a variety of different colors such as red, green and blue. With the wavelength of light. Lightness (brightness) is the brightness of that color. Different shades of brightness is different, even if the same surface color due to the nature and intensity of light will produce a different shade, shades of difference. Such as yellow, can be light yellow, yellow, dark yellow and so on.<
