4) * light than the same visual space screen chiaroscuro. * Visual experience of light and shade effects - the use of physiological characteristics of the eye to design, from the eyes into the dark visual photopic state requires approximately 15 to 30 minutes, while the time required to enter the photopic state is relatively short from the dark vision. Therefore, performance lighting scenes can be designed according to the contents of the script the plot, intended to distinguish between light and dark intensity of each scene. * Holistic; stressed parts. The brighter overall stage actor darker contrast of light and shade and color the size may produce different visual change in the same screen space. * Character modeling master light and auxiliary light and shade and color contrast: to show visual appreciation needs to be set. 2: 1,5: 1,10: 1,30: 1,50: 1,100: 1 range. * Compare the main characters of light and non-light main characters: the same environment and you want to show the difference between primary and secondary relationship based on intent space level, 2: ranging from 1: 1,3: 1,5. * Comparative figures light and ambient light: 2: 1, 5: 1, 10: 1 range. * Foreground, middle ground, background light ratio: 2: 1 to 10: 1 range. * The brightness and color contrast scenes and performances scene images of space: use the time plot development changes; seasonal variation; scene change: changes in brightness; contrast color change.

5) Zone * light projected onto the regional distribution of the stage or performance space as well as the difference between the inner and outer zones. * In front of the stage after the performance area, the left-right divide is based on the design of the illumination area. * Partial or overall performance needed for development plot area to be illuminated. * Performance area lighting and scenic lighting.

6) a bit of light light projection direction: refers to the specific location of the lamp in which the three-dimensional space. These include, surface light, ears, mouth column table light, light foot, light station roof of the mouth, the top row of the condenser, the top row floodlight, day light row, row to light, the light side of the bridge, the flow of light, side light, (hanging cage bench) chasing light and the like. * Plot development in the desired direction performance: backlight light, sunrise and sunset, dawn dawn like. * Required performances zones particular lamp-bit designs.

(1) Lighting: - matt no body to control the light and dark as a means of rendering form.

(2) shaping the image of: - depicting the characters of character, show the effects of different space scene.

(3) Light ratio adjustment - the pursuit of a good visual effect; the actual effect of contrast; visual contrast.

(4) space-time atmosphere: - the performance of a given situation normalized needed time and space atmosphere.

(5) relating to the performance of: - the color associated with lighting and other visual vocabulary.

(6) Communication in Performance Relationship: - facilitate emotional communication between the actors and the audience.

(7) illumination (direct light): - facilitate emotional communication between the actors and the audience. * Illumination: surface per unit area of the obtained flux. Is uniformly illuminated object, when on 1 square meter area of the resulting flux is 1 lux, the illumination surface is 1 lux; therefore 1 candela point light source as the center and the radius of 1 meter in the sphere illumination produced is called 1 lux. Lux letter or express Lu. * Irradiation intensity is determined by the distance power and design as well as the projection surface between the light source. Light source intensity, the higher the illuminance; the closer, the higher the illuminance. * Illuminance is irradiated surface level but also with the value of the projected light angle about, the more likely that the vertical distribution of light, the higher the illuminance. * Illuminance inverse square law: the same light, vertical illuminance irradiated surface and it is inversely proportional to the square of the distance from the light source. For example: If the floodlight to move backwards 2 times the original distance illumination area increased 4 times, only a quarter of the original illumination value; If you move back 3 times, the illuminance value diminished 9 times. Conversely if you move forward from the original luminance value of 1 and a half four-fold increase. Usually focus on measuring performance in vertical illumination source applications. * Degree of vertical illuminance: Stage illumination level determines the level of brightness stage mesa; determine the level of vertical illuminance.

(8) Brightness: The brightness of the surface luminous intensity values. Whether the surface is its own light or reflected light, or transmitted light, as long as it is from the surface of the "issue" Light of view, we can call it a light emitting surface. In the luminous intensity per unit area of both brightness of the object surface. In the same light-emitting surface, different brightness values orientation. Brightness measurements are generally in a direction perpendicular to the line of sight will be the light emitting surface in luminous intensity per unit area is called brightness. The light intensity constant, the smaller the projected area of the light-emitting surface, the brightness, the greater the projected area of the light-emitting surface, the lower the brightness. A unit of luminance is nit (nt). 1 nit = 1 cd / 1 square meter. Secondly, the reflectance of the object, the higher the brightness. Under the same light, white and black object reflectivity is different according to different light reflection and absorption capability, different surface brightness. In addition, there are still actual brightness brightness brightness concept and visual concepts. Visual brightness referring to the brightness of the visual senses, in low light conditions and strive to make the audience feel comfortable watching the performance of visual brightness, namely the use of people's visual physiological characteristics, resulting in luminance higher than the actual physical effect. Horizontal and vertical illuminance illuminance: Stage illumination level determines the level of brightness stage mesa; vertical illuminance determines the level of brightness of the audience to see the characters and visual effects scenes. Performance applications typically focus on measuring the brightness of the object according to the reflected light.

(9) Color: Color temperature is a "full radiator" to represent the spectral content of the actual light source, which is based on absolute zero "Kyle text." Scale (-273 ℃) as a benchmark to K (or K ) symbol. With increasing temperature, the blackbody radiation color change, starting with the dark red into the yellow, blue and finally converted into white. "Full radiator" at different temperatures radiated spectral components, will produce a series of radiant light and color changes. As the temperature change "full radiator" emitted by the wavelength spectrum of the light and consistent hue, at this time is "full radiator" color temperature. Color is the color temperature of the light source based on objective figures to represent the concept of physics, it does not refer to the color temperature of light. The lower the color temperature of the light source, a warmer light color more visual effects. The higher the color temperature of the light source, the light color bias cool visual effects. For example: tungsten as the voltage and increases the filament temperature increase as the filament light source whose color temperature is from red to white. Voltage drop 1V color temperature is decreased by approximately 8K.

(10) CRI: refers to the level of color rendering light source illuminating the subject visual quality evaluation. This evaluation is based on the reference value of light seen color index-based, full-color spectrum of the object under illumination, as reflected in the truest color. Sunlight is the best play isometric color full-color light, stage lighting and video in addition to high luminous efficiency requirements, and requires a good light source color rendering properties, less color distortion is irradiated object. For example: 1kw ~ 2kw halogen lamp stage lighting color rendering index can reach 100 assessment, and mercury lamp color rendering index of only 50 evaluation. * Direct light: or so-called direct illumination light. * Reflected light: brightness of the light through the reflective surface obtained. * Diffuse light: or so-called indirect illumination. * Transmitted light: the brightness of the light by different light-transmitting material obtained.
