Main points of professional stage lighting design

1. Research on the characteristics and performance of lighting equipment and equipment Floodlights: heaven and earth row lights, footlights, top row floodlights, etc. Spotlight: convex lens spotlight, soft spotlight. Lensless spotlights: backlights, PAR lights and closed bulbs.

Including: parallel, concentrating, soft, astigmatism and other imaging spotlights: modeling lights and imaging inserts, follow spot lights. Slide effect lamps: water ripple slide, cloud running slide, PANI slide and other effect lamps, etc. Computer lamp: a lighting fixture that integrates color change, imaging shape, and motion change in the form of lamp body rotation and mirror movement.

Special projection lighting: effect equipment, color changer, fogger, digital computer projection equipment, etc. The functions of each part of the operation control system SCR dimmer and dimming console. Colored light filters: various color filters, color temperature, light reduction, reflective film, soft light film, etc.

Demonstration laser: use various low-power laser generators to complete the scanning of the screen under the control of the computer. Auxiliary effect equipment: smoke generator, exhaust and air supply device. Snow generating device, soap bubble generating device, carbon dioxide smoke, liquid nitrogen, fried tobacco, paper fireworks, dry ice, etc.

2. Research on the material characteristics of lighting and illuminated objects. Use the performance of materials - reflection, diffuse reflection, light transmission, semi-transparency, opacity, softness, hardness, softness, absorption and reflection law. Material - Textile Material - Cotton Satin Velvet Linen Gauze. Metal material--gold, silver, copper, iron, aluminum alloy, stainless steel.

Natural material - wood, stone, earth brick and plant synthetic material - nylon plastic foam material PVC sheet. Smoke material--ethylene glycol smoke oily lingering smoke dry ice low-layer smoke fried smoke liquid nitrogen performance--front projection, reverse projection, plane, three-dimensional, relief, texture, point, line, surface, layer, penetration, halo Silhouette, half silhouette, etc. Performance characteristics--mesh, rope, strip screen, pillar, veil, strip screen, frame, light box, etc. 3. Research and basic concepts of lighting modeling: feeling and performance Study the four elements of lighting arrangement 1) Key light: Determine the direction of the main light based on the theme and viewpoint. The main light is stronger than other lights, and hard light such as spotlights is used for lighting.

2) Auxiliary light: It is an auxiliary and supplementary to the main light, and plays a decorative role. Simulate the reflected light of the natural environment with soft lighting. 3) Backlighting: add light on top of the main light.

It can be stronger than the main light, or it can be lower than the main light and stronger than the auxiliary light, and it plays a decorative role. 4) Light ratio: the light and dark ratio of the body to the light received by all parties. The light ratio can be adjusted according to the creative needs, so as to obtain the ideal effect.
