How to install stage LED lights to look good? The gods help!

Stage lighting what color stage lighting and film lighting design principles and lighting techniques a stage lighting lighting stage lighting is broadly divided into theater stage lighting and variety show lighting, which is mainly characterized by the ornamental effect of the scene, often with a certain degree of artistic subjective abstraction. 1. Theater stage lighting According to the different repertoire, the requirements of the lamps and lanterns are different. Here the basic lighting configuration of the theater stage refers to the basic to meet the general opera, dance, ballet, drama, local theater and other performance needs. Downlight, also known as RAP lamp, its structure is installed in the cylinder mirror bulb or in the reflective bowl installed tungsten bromine bulb, the main feature is able to shoot a more fixed beam of light beam angle wide and narrow a variety of, but the size of the spot can not be adjusted; the sky row of lamps, row of lights on the ground, the high-power diffusion lamps, used to irradiate the upper and lower canopy with the requirements of bright and balanced light, irradiation area is large; imaging lamps, or modeling lamps, ellipsoid lamps, the beam angle has a variety of, can be selected according to the needs of the performance. Angle has a variety of applications can be selected according to need, the main feature is that the light spot can be cut into square, diamond, triangle and other shapes like a slide, or project the required variety of patterns and patterns, the power is also 1KW, 2KW and so on can be selected to configure; there are fewer and fewer applications of spotlighting, the spotlighting on the stage refers to the front of the lamp using the plano-convex condenser mirror, the lamp can be adjusted to adjust the size of the light spot, and come out with a more concentrated beam, next to the diffuse beam, and the light beam is more concentrated. The beam is more concentrated, next to the diffuse light is relatively small, the power of 0.5W ~ 5KW variety of focal length has a long, medium, short points, depending on the distance between the shooting distance can be selected as needed. Stage lighting lighting with light more than a fixed point light source, with different colors to achieve a variety of visual effects. Stage lighting first respect for the human eye, that is, give full consideration to people's viewing habits, on the basis of the molding. 2. Variety show lighting Large variety show is a long-lasting art form, and the rapid development of its form more and more diversified, such as the Spring Festival gala, a variety of thematic nature of the evening, the commemorative evening of the different festivals, etc.; from the scene, more and more complexity, there are different types of auditoriums, amphitheaters, arenas, sports stadiums and squares, etc.; from the audience, the level of more and more, the number of people is more and more; from the form of the program, the more the number of people is more and more. More and more; from the program form, there are music, dance, drama, opera and so on. The lighting design of variety show is based on stage lighting, incorporating many new elements and using advanced lighting equipment, paying more attention to the diversity of angle selection. In the choice of lamps and lanterns, most of the evening variety show used advanced computer lights, the overall lighting basic illumination control in the range of 800LX ~ 1000LX, the use of zonal lighting, the front area of the illumination in the range of 2000LX ~ 2500LX, in the middle of the illumination of 1500LX ~ 2000LX, the back of the area of the illumination of 800LX ~ 1000LX, but also the changes in the light effect of the rapid and varied. Another feature of concern is that, in order to meet the needs of television broadcasting, variety show light also has to take into account the color rendering of the light is consistent with the camera, not only to be suitable for the human eye to watch, but also to meet the requirements of the camera shooting. Film and television lighting film and television lighting is broadly divided into film lighting and television program lighting, which is characterized by more objective and natural light effects, the pursuit of light effect authenticity, rationality, and more consideration of the coordination of recording equipment and the light source when lighting. 1. Movie lighting movie lighting is divided into location lighting and indoor lighting. Location lighting generally respect the laws of natural light, try to reproduce or moderately supplement the natural light effect; indoor lighting requires full consideration of the characteristics of light-sensitive materials, based on the type of film and sensitivity of the use of different types of illumination and color temperature of the lamps and lanterns. The selected lamps are mainly traditional lamps, but the power is relatively large, and the color temperature of the light source is high. At the same time, we should also pay attention to the tolerance of light-sensitive materials, strict control of the light ratio. 2. Television program lighting Television program lighting is mainly divided into film and television drama lighting, studio lighting and television news location lighting and other aspects. (1) film and television drama lighting film and television drama lighting and film lighting is relatively close to the difference is that the camera for the illumination of the adaptive range to be weak, but the adaptability of the color temperature is better than the film. (2) studio lighting studio lighting as a special plastic light effect has its own characteristics, that is, before determining the lighting program, a detailed understanding of the performance characteristics of the recording equipment used, and the facial features of the announcer to make an analysis of the study, but also to take into account other modelling means (such as hair, clothing fabrics and colors, etc.) on the impact of the character modeling, so as to achieve the desired effect of the picture through the lighting. The brightness of the background light should be lower than the character light, and the ratio of the character light should be between 1:1.5 and 1:2. Minimize shadows when lighting and keep excess light behind the announcer. In the use of color should not be too deep, too mixed, it is appropriate to use light tones or neutral colors, too much color will affect the announcer's clothing and image, resulting in a hustle and bustle. Also according to the facial features of male and female announcers, to determine the main light position. If the two faces differ greatly, the main light needs to be set separately, and the height and angle of the light position should be determined according to the character's face. The main light is the main light source of the character modeling, is to shape the character image, reflecting the character outline and skin color temperament of the light, the light orientation angle should be based on the character's face and facial features. In general, the main light in the announcer facing one side. Lighting in the female announcer's light position should not be too high or too Answer the person's supplementary 2009-06-08 12:21 side, the position of the main light is generally in the parallel degree of 30 ° ~ 50 °, the height of the nose in a sitting position when the shadow and then a little below the best. General auxiliary light shadow do not over the bridge of the nose, to avoid butterfly nose shadow, brightness and the ratio of the main light brightness to 2:1 to 2:1.5 is appropriate. Face light is used to irradiate the front of the character, the light position is generally in the character's facial height on the upper side, in the machine position on the throw of about 30 °. Can also be used double light face light, that is, the first soft light for facial lighting, and then use a small light plus eye light. Contour light is used to outline the character lines and three-dimensional outline of the light, it can enhance the depth of the picture, highlighting the people and scenery space level, in the character modeling can reflect the texture of hair accessories, shoulder clothing, three-dimensional sense.
