Currently, there are many agencies, institutions, associations, enterprises and so built their own halls, auditoriums, function rooms and other Arts areas need to configure some of the appropriate professional lighting facilities, lack of knowledge of stage lighting, the right choice in how to professional lighting equipment, and not very proficient; and a lot of professional lighting equipment vendors, professional stage lighting equipment is also little knowledge, can not be correct by the guidance, so that waste of money. To avoid this situation, this basic knowledge of stage lighting to make some brief introduction.

         First, the stage lighting in order to do the usual light-bit configuration of professional stage lighting, stage lighting channel should first understand the common light bit. This is the correct selection of an important part of configuration.

         1, the surface light: the front toward the stage from the audience at the top of the light, the main effect of lighting for the characters and the entire front of the basic optical shop contamination.
         2 ears: in the estuary on both sides of Taiwan, oblique light cast on the stage, divided into upper and lower layers, the main auxiliary plane light, enhance facial lighting, increase the figure, three-dimensional scenery.

         3, the column of light (also known as edge-lit): Since the units of light projected on both sides of the mouth, mainly for the characters or the scenery on both sides of surface lighting, increase the three-dimensional outline of sense.
         4, top light: from the stage above the stage toward the light, from front to rear into a row of roof light, the second row of the top light, top three rows of light ... ... and so on, mainly used for general stage lighting, enhanced illumination stage, and there a lot of scenery, props fixed-point radiation, mainly by roof light to resolve.

         5, Backlight: reverse the direction of projection from the stage light (such as the top light, back light bridge light, etc.) can be sketched out the characters, King said that the contours, and enhance a sense of three-dimensional and transparent, but also as a specific source.

         6, the bridge of light: the stage at the bridge on both sides of the stage toward the light, mainly for supporting column of light, enhanced three-dimensional, but also for other optical projection of the direction bit inconvenient, but also as a specific source.

         7, foot of light: from the proscenium stage in front of units projected to the light board, the main supporting surface light illumination and eliminate exposure to surface light and other high figures formed by the face and chin shadows.

         8, World ranked light: from the sky above and below the canopy toward the light, mainly for the canopy lighting and color changes.
         9, the flow of light: in the flow of light shelves on both sides of the stage, the main auxiliary bridges light, added on both sides of the stage lighting or other specific light.
         10, the spotlight: the auditorium or other location required from the light-bit, mainly for tracking performance or highlight a particular cast of light, but also for the host, is the art of close-up stage of the pen, play dragon eye-dotting the surface effect.

         Second, the common characteristics of lamps and

         1, the spotlight: the stage lighting is the most widely used one of the main lamp types, the current market 1KW, 2KW, 2KW to the most widely used. It focused on the light exposure, spot clearer outline of the edge, to highlight a local, but also an area to zoom in spot lighting, as the stage for the main light source, commonly used in the surface light, face, side light and other light bits.

         2 Soft Light: light soft symmetry, both prominent a part, and no blunt spot, easy to link up a few lights, a common 0.3KW, 1KW, 2KW, etc.. Used for columns of light, mobile and other close-light bit of light.

         3, back to the light: it is a reflection of the lamps, which is characterized by light quality hardware, according to high and long-distance, is an economic, efficient and light lamps, common mainly 0.5KW, 1KW, 2KW, in order to use up to 2KW.

         4, astigmatism light: diffuse light, are said projected area, is divided into days of discharge and drainage of astigmatism astigmatism, a common 0.5KW, 1KW, 1.25KW, 2KW, and many more for the sky radiation, can also be used for theater Chairman Taiwan's general lighting.

         5, the modeling lamp: Principles between the chase between the light and the spotlight is a special lamp, mainly for the characters and scenery modeling project.
         6 foot light (also known as bar lights): soft lighting, the wide area. Mainly as the medium shot, Netscape light cloth, cloth color, the location can also be assisted in Taiwan port side lighting.

         7, light beam lights (also known as Downlight): currently used more widely, such as PAR46, PAR64 models. Can be used for all position figures and scenery lighting, also can be installed directly on the stage, exposed to the audience to form a light array, for the dual role of the stage decoration and lighting. 8, King slide and canopy effects cast light: in the stage to form an overall picture on the sky, and all kinds of special effects, such as: wind, rain, thunder, electricity, water, fire, smoke, clouds and so on.

         9, the computer lights: This is a RS232 or PMX by the DMX512 signal control or intelligent lighting, and its light color, spot, are better than more conventional lighting illumination in recent years developed an intelligent lighting, often installed in the surface light, top light, the stage level positions, such as the operation of the color, shape, maps, etc. can be compiled to run programs. As the power of different sizes, using the stage to be different. General low-power computer lights, only suitable for ballroom use. Low-power computers in the stage lighting cable, spot often spotlight, such as talk of back light off, so in the selection, we should pay special attention.

         10, chasing light: Yes, stage lighting lamps, characterized by high brightness, the use of lens imaging, can present a clear spot, by adjusting the focus, but also to spot changes in the actual situation. There is activity light bar, you can easily change the color, light body can be free running and so on. More varieties currently on the market, mark targets are not the same way to power as the standard, such as: 1KW halogen light source, 1KW Dy light, 1KW metal halide light source, 2KW metal halide light source, but also to recover from a standard light light (in light intensity under a certain distance, illumination), such as 8-10m ,15-30m chasing light chasing light ,30-50m ,50-80m chasing light chasing light, etc., and function is divided into: Mechanical chasing light, its focus, light bar, change color are done manually; another way for the computer chasing light, its focus, light bar, change color, adjust the color temperature are automatically done by push-pull electrical, so Be sure to choose carefully selected a variety of indicators.

         Third, the stage light color changer color changer design promotion, greatly simplifying the number of stage lighting, reducing the labor intensity of the light workers, but also saves the amount of investment, so it is now an indispensable instrument configuration stage , currently on the market are mainly mechanical and electrical devices for color and color changers two.

         1, stage machinery, color changers: its design is simple, lower prices, 80 to 90 of 20 mid-century mainstream products, currently close to eliminated.
         2, computer color changer stage: in recent years developed a new color changer, which uses the international standard DMX-512 signal output, controlled by dedicated control Lu, can also be connected to the computer lighting console to use, how it mode, high-precision, large capacity, control, distance and so on, become the mainstream market, color changer products.

         Fourth, lighting control dimmer equipment currently on the market, there are analog dimming and digital dimming, which is characterized by:
         1, analog dimmer: use analog dimming technology, the output signal is 0-10V-one output. Generally designed to be simple analog dimmers, controllers road less dimming curve is poor, but the market price is lower, easy to learn to master, as the 20th century, late 70s to the mid 90's mainstream products. Common are 3-way, 6 way, 9 way, 12 Road, 18 Road, 24 Road, 60 Road, 120 Road, etc., each power mostly 8KW, but there are 2KW, 4KW, etc., the path a few more as one of the machines, road number of split type.

         2, the digital light modulator: Using sound machine technology, for the DM512 digital signal.
Easy to use digital dimming sets (especially the big loop), the dimming function, backup functions, grouping functions, dimming curve sets were better than analog dimming, performance, reasonable price, very popular with customers. Common are 12, 36, 72 Road, 120 Road, 240 Road, 1000 Road, etc, each mostly 2KW, 4KW, 6KW, 8KW and so on. In understanding the lights, lighting features and control equipment and color changer, you can according to their characteristics, the use of the size,
