In professional stage performances, fascinating lighting is a very important component. It can drive emotions and boost your emotional impact on your music.

If you have a dedicated lighting technician in your team, you can use industry terminology in the field of lighting to make your communication more efficient. Here are some basic terms that you need to know about the field of lighting.



Atmospherics: Particles that are released into the air to enhance the visibility of the lighting effect.
Common examples include: mist, fog and dry ice. The mist is almost undetectable, and its sole purpose is to let it reflect light. The effect of the fog is more awkward and more easily noticeable. Dry ice fog will remain in a lower position, closer to the floor, and you can recall the scenes in those monster movies or in the cemetery.

Beam Angle: The angle of the beam used to measure (in degrees) to indicate the angle at which light is emitted from the lights. The light emitted by the lights is conical, and the beam angle helps you determine the size of the illuminated area based on the distance.

Derby: A lighting effect that projects many fast-moving, sharp, multi-colored beams over a wide range.

D-Fi: The technology used in Oppray's lighting products provides wireless DMX functionality for the device. Allows you to control your lighting with a DMX controller or other smart device, wireless control, without the need for a connection cable.

DMX: Abbreviation for Digital Multiplexing, a serial data protocol that controls most lighting devices. Most LED lights use multiple DMX channels. The meaning of DMX in the field of lighting is just like the meaning of MIDI in the audio field.

Effects: Effects, used to add an atmosphere to the stage, color and visual effects. It consists of basic lighting fixtures, lasers, fog machines and more.

Ellipsoidal Reflector: An ellipsoidal mirror that is a mirror that converges light to a point, placing a point source above a focus, and the emitted light converges to another focus. The width of the beam reflected by the ellipsoidal mirror varies according to the distance between the two points. The shape of the ellipsoidal mirror is similar to the end of the ellipsoid. It is sometimes called Leko.

Ellipsoidal Spotlight: ellipsoidal spotlights, spotlights with elliptical mirrors and visors, and occasionally iris diaphragms and pattern slots.

Facade: Similar to the backdrop, but it can be placed directly in front of the DJ, not just behind the DJ or around the room. Normally, the Facade will be your "showcase" and the DJ will stand behind it.

Framing Shutters: Framed blinds, sometimes called visors, can move light from a unit to block light from certain areas.

Fresnel Spotlight: a Fresnel spotlight with a Fresnel lens. This type of luminaire is capable of providing a beam with a blurred outline, usually containing a spherical mirror and an adjustable focal length that covers the full range between the spotlight and the floodlight.

Gobo: A curtain or board placed in front of a spotlight to cover certain areas and let the light project some shape.

Iris Diaphragm: A variable aperture, also known as an iris diaphragm, is a circular opening made up of a series of thin movable metal plates. The diameter of this opening is adjustable so you can change the diameter of the beam or mechanically dim the light.

Lens: lens, lens. Made of transparent material, usually glass. The lens allows the light to bend as it passes. Colored lenses can be used to create colored lights.

Moving Head: Moving head light with luminaires that are either automatic or mechanical. Moving headlights can be controlled by sound or controlled by preprogrammed or DMX to create complex and fascinating lighting.

PAR: PAR is an abbreviation for Parabolic Mirror - used as a general staining lamp that illuminates areas larger than 6-8 feet in diameter and has a parabolic shape.

Pattern Slot: A pattern slot that is a narrow opening that can be inserted into a pattern frame or pattern rotator. The pattern holder can add a pattern to the projection of the light, while the pattern rotator can switch the projection pattern.

Prism: Prism, used in moving heads, refracts light, illuminates the beam to a larger space, and makes gobo's effects look more interesting.


Scrim: A base fabric, a translucent material that allows some light to pass through. It allows the light to produce diffuse reflections that increase the color and dynamics of the light.


Spot: Abbreviation for Spotlight - Used to highlight an important small area to condense visual attention. Spotlights can also be placed with gobo patterns such as logos and logos.

Strobe: The flash has a strong lighting effect that can be turned on and off quickly. If used in a dark place, it can produce a stroboscopic (flashing, slow motion) effect.

Wash: A dyeing lamp, a type of lighting that covers a large area.

WiFly: The technology used in ADJ's lighting products provides wireless DMX capabilities. Enables you to control your lighting with a DMX controller or smart device, wireless control, without the need for cables.

RGB (red, green, blue): A color mode that adds color, using a combination of red, green, and blue light to produce a variety of other colors.

RGBA (red, green, blue, amber): The alpha mode of the alpha channel is added to the RGB color mode. This extra channel is used to indicate the opacity of each pixel. By using alpha blending, you can use a transparent area to combine one image onto another, and if you use an opaque area, you can make the edges smoother.

RGBAW + UV (red, green, blue, amber, white, UV): Adds the color mode of the white channel and UV channel to the RGBA color mode. These additional channels provide more color mixing and a wider color gamut than four-color LED luminaires such as hot pink, lemon green and electric blue.
