Talk about the regulation of stage lighting use and application effect

During stage lighting design the use of light color is an important means of dramatic art and by using light colors we must master its skills and laws.

Light color addition and Light color subtraction

The deployment of spices adopts the “Light color subtraction” law which is common in color science. Knowing this rule, the use of color filters can call up the desired superposition of various light colors. If we put the superposition of different types of filters together we can obtain variety of light color by the light in stage lighting. Stage Wash Par Can Uplighting also uses this ” Light color subtraction ” rule of drawing palette. But it is worth mentioning that the stage lighting not only has to use this method,But also need to use the “light hue plus” approach to obtain different light colors. Namely, the regularity of three primary colors of light of red, green, and blue are added to white.

Discussion of stage lighting luminous body and filter applications

Theatre performance is the art seen by naked eyes, but is different from Color film or television felt by the optic nerve. Human eye color cells are weak in the dim light does not distinguish color.

The important issues of stage Lighting need to be resolved without the aid of a gas discharge lamp or development of a metal halide lamp, improving the brightness and purity cool lighting is very difficult.

At present, with the above-described methods, Professional Stage lighting’s dimming is not ideal, which limits its use on stage. The average voltage drops by the use of a warming light color cast, especially the impact of varying luminous light. Over the years it has been able to study the use of fluorescent to solve this perplexing problem. In recent years, film and television began using trichromatic fluorescent lamps of frequency dimming fiber optic lines. Now filters used in stage Led Flat Par lighting are mostly ester resin dyed material, which is convenient but is difficult to avoid never fade. Filters from well-known manufacturers are up to hundreds of species, which are often called micro-filter. Difference between two pieces of filter is very small. Because television is very sensitive to light color, two types of filters with small difference can be visually distinguish, while it is almost unacceptable in film industry. But for stage lighting, the requirement is not so high.

Because polyester resin filters are hard not to fade, some foreign repertory theater performances remain the habit of using colored glass filters. Stained glass is produced by adding some of the metal or an oxide in the molten glass to produce different colors, and its color does not fade. This can guarantee the quality of the repertoire performance not to change.
