Lighting: Stage Tech 1

A circuit dimmer number refers to a number that identifies the stage circuit into which an instrument should be plugged in. This number helps to ensure that each instrument is connected to the correct circuit and can be controlled or adjusted accordingly. It is not a boring number or a broken circuit, but rather a useful identifier in stage setups.

A dimmer is a device used to control the amount of light. It allows users to adjust the brightness of a light source by increasing or decreasing the voltage supplied to it. By doing so, the intensity of the light can be adjusted to create different atmospheres or meet specific lighting needs.

An instrument schedule is a document that contains detailed information about each instrument used in a production, including technical data. It serves as a record of all the instruments and their specifications, allowing for easy reference and organization. Additionally, it is also referred to as a hookup sheet, which further emphasizes its purpose in recording the technical aspects of the instruments. Therefore, the statement that an instrument schedule is a form used to record all of the technical data about each instrument used in the production is true.

A focus area refers to an area where the light should be concentrated or directed. In the context of lighting design for a plot, it is an area that is designated for focused lighting, and it is identified by a specific letter.

Amps, short for amperes, is a unit used to measure electric current. Current refers to the flow of electric charge in a circuit. It is the rate at which electric charges pass through a given point in a conductor. The higher the current, the greater the amount of charge flowing per unit of time. Therefore, the correct answer is "current" as it accurately defines what amps represent in the context of electricity.

A light plot is a scaled drawing that provides a top view of where the lighting instruments should be placed. It helps the lighting designer and technicians to determine the exact locations for hanging and focusing the lights in a performance space. This drawing includes details such as the type of lighting fixtures, their positions, and any other necessary information for the lighting setup.

A color media refers to a material or substance that is used to alter or enhance the color of light. In this context, a gel is a type of color media commonly used in photography, film, and stage lighting. Gels are transparent sheets made of colored polyester or polycarbonate that are placed in front of a light source to change the color of the light emitted. They come in various colors, including cyan and magenta, and are widely used to create different lighting effects and moods in visual productions.

Voltage is a measure of the potential pressure or difference in electric potential energy between two points in an electric circuit. It represents the force that pushes electric charges through a conductor, causing electric current to flow. Voltage is often referred to as potential pressure because it is similar to the pressure in a fluid system that causes the fluid to flow.

The beam designation is used with Ers's ellipsoidal reflector spot. This suggests that the beam designation is a term or code used to classify or describe the type of beam produced by this specific type of lighting fixture. It is likely that different beam designations correspond to different beam angles, shapes, or qualities, allowing users to easily identify and select the desired beam characteristics for their lighting needs.

Ohms is a unit of measurement used to quantify electrical resistance. Resistance refers to the opposition that an electrical circuit or component offers to the flow of electric current. It is measured in ohms and determines how much current will flow through a circuit for a given voltage. Therefore, the correct answer is resistance.

Ellipsoidal, parabolic, and spherical is correct!

The given information states "find amperage: 5-150 watts" and the answer provided is "7.5". Since the question is incomplete and does not provide any context or further details, it is difficult to determine the exact meaning or intention behind it. However, one possible interpretation could be that the question is asking for the amperage corresponding to a power range of 5-150 watts, and the answer "7.5" represents the amperage value for that power range.

Wattage refers to the rate at which work is done or energy is consumed or produced. It is a measure of the power used by an electrical device or system. The unit of wattage is watts, which is equal to one joule of energy per second. Therefore, the correct answer is "work" because wattage is directly related to the amount of work being done or the energy being transferred or transformed.

A hanging card is a section of the lighting plot that is handed out to show where a small section of lighting instruments belong

A lighting section is a side view scaled drawing that shows the position of lighting equipment in relation to the set and physical structure. This drawing helps in planning and implementing the placement of lights for a performance or event. It provides a visual representation of how the lighting equipment will be positioned and how it will interact with the set and physical structure. This allows the lighting designer to effectively design and execute the lighting design for the production.

The correct answer is concave and convex. Concave lenses are thinner in the middle and thicker at the edges, causing light rays to diverge. They are used to correct nearsightedness and are commonly found in glasses. Convex lenses, on the other hand, are thicker in the middle and thinner at the edges, causing light rays to converge. They are used to correct farsightedness and are also found in glasses. Both types of lenses have different properties and applications in optics.

A cut list is a list of every gel to be used on every fixture. Gels are colored filters that are used in stage lighting to create different effects and colors. The cut list helps in organizing and planning the use of gels by specifying which gel should be used on each fixture. This ensures that the correct gels are used in the right places, allowing for precise and consistent lighting design during a show.

Direct current (DC) is a type of electric current that flows in only one direction. In a direct current, the flow of electrons is from the negative terminal to the positive terminal. This is in contrast to alternating current (AC), where the flow of electrons constantly changes direction. Therefore, the correct answer is "One that moves negative to positive" as it accurately describes the direction of the current flow in a direct current.

A gobo is a gate accessory used in lighting fixtures. It is a thin metal or glass plate with a pattern or design cut into it. When placed in front of a light source, it creates a patterned or textured effect by blocking or shaping the light. Barn doors, dimmers, and yolks are not gate accessories. Barn doors are used to control the direction of light, dimmers are used to adjust the intensity of light, and yolks are used to mount lighting fixtures.

Alternating current refers to a type of electrical current that constantly changes direction. It moves back and forth, oscillating between positive and negative directions. This change in current is what distinguishes alternating current from direct current, which flows only in one direction.

In this context, a channel refers to two different things. Firstly, it is something that you watch on TV, typically referring to specific TV networks like Disney Channel. Secondly, it also refers to the assigned channel for an instrument, specifically in the context of how a light board controls light. This means that the correct answer encompasses both meanings of the term "channel" in this particular scenario.

The focal point refers to the point where light rays converge after passing through a lens or reflecting off a surface. This convergence of light rays is a result of the lens or reflecting surface's ability to bend or focus the light. At the focal point, the light rays come together, creating a focused image or a point of maximum intensity. The focal point is an essential concept in optics and is utilized in various optical systems such as cameras, telescopes, and microscopes.

The ellipsoidal reflector spot consists of several parts including a focus knob, shutter, lens, lens train in soft focus position, focal point, lamp, lamp base, gel frame holder, instrument housing, ellipsoidal reflector, filament of lamp, and pin connector. These components work together to control the focus, intensity, and direction of the light emitted by the spot. The focus knob allows for adjusting the sharpness of the beam, while the shutter controls the shape and size of the beam. The lens and lens train help in achieving the desired soft focus effect. The lamp, lamp base, and filament provide the light source, while the gel frame holder allows for adding color filters. The instrument housing houses all the components, and the ellipsoidal reflector helps in shaping and directing the light beam. The pin connector ensures proper electrical connection.
