How do small mirror ball in the center of the stage?

Mirror ball is a new ball composed of small glass mirrors attached to a ball that can reflect different types of light. It was once the shining light ball of dance halls, but now it is the finishing touch in creative space design. How did it achieve this?

Key points of production process and technology

The production of mirror balls is a fine carving process from macro to micro. First, select optical glass (such as BK7, fused silica) or sapphire and other materials. After cutting the raw materials, rough ball blanks are formed through rough grinding, and then gradually approach the design dimensions in precision grinding. The most crucial step is polishing, usually using asphalt polishing technology. Professional equipment is used to roll the ball blank in the polishing solution, ultimately obtaining a mirror like smooth surface and extremely high sphericity. Thus, the most critical lens production was completed;

Next is the ball embryo attached to the production lens. At present, most of them use foam ball embryo, which is easy to shape, easy to make mold, light in weight, and not fragile. Select different sizes of glass lenses according to different sizes, and carefully stick them to the embryo body manually or by machine. During the production process, it is necessary to pay attention to whether the lenses are damaged or smooth like mirrors. Defective lenses need to be picked out and replaced.

Range of dimensions for mirror balls

This article is mainly for the mirror balls for commercial use. The diameter range is mainly 2 cm to 200 cm. If the diameter is not larger, the safety factor should be taken into consideration. Because most of the mirror balls are suspended, the glass lens itself has a certain weight. A mirror balls with a diameter of 2 meters foam bulb weighs 85-335KG, which is larger and heavier.

How to make colored mirror balls?

In the past, the production of colored mirror balls mainly relied on the characteristics of the material itself: adding metal oxides (such as cobalt to appear blue and chromium to appear green) to the glass formula to melt and produce a uniformly colored glass, and then grinding it into balls. This method has uniform colors, but the types of colors are limited and cannot produce complex patterns.

Nowadays, the production methods are more diverse and flexible. In addition to using traditional pigment glass, it is more common to use coating technology: by coating multiple layers of dielectric or metal films on the surface of transparent mirror balls, specific transmission or reflection colors can be interfered with, and even gradient colors can be achieved. This process not only achieves rich colors, but also endows the mirror balls with additional optical functions such as anti reflection or light splitting.

Gorgeous Turn of Application Scenarios: From Dance Halls to City wide Carnival

The application of mirror balls has undergone a transformation from "functionality" to "coexistence of functionality and art".

Previously, mirror balls mostly appeared in dance halls or discotheques. The sparkling sphere hanging from the ceiling disperses a beam of light into countless dots, creating a hazy and dreamy dance floor atmosphere as the motor rotates. It was an indispensable iconic element in the nightlife of that era.

Nowadays, mirror balls have already left dance halls and become the atmosphere for various celebration occasions and festivals, with diverse application scenarios

1. The finishing touch on the Christmas tree: Hanging small colored mirror balls on the Christmas tree, combined with warm toned string lights, makes the traditional Christmas tree shine with brilliant starlight effect. The light reflected by the sphere falls onto the gifts and walls, instantly filling the entire space with festive magic.

2. The flowing starlight of the carnival: On the parade floats of the carnival, large-sized mirror balls are matched with dynamic colorful lights, changing colors with the rhythm of music, projecting a joyful atmosphere onto the crowds of the entire street. It no longer hangs still, but becomes a mobile pleasure maker.

3. The ceremonial feeling of New Year's Eve countdown: At the New Year's Eve event, a giant mirror balls slowly descends from a high altitude, and with the countdown of the entire venue, it becomes the focus of attention. When the lights are focused and countless light points are scattered towards the crowd, the sense of ceremony at that moment is irreplaceable.

4. Romantic atmosphere for weddings and celebrations: At outdoor lawn weddings, small mirror balls are decorated in floral backgrounds, reflecting the mottled light and shadow of afternoon sunlight; In the banquet hall, it can also spread candlelight like warm light throughout the entire space, creating a warm and romantic atmosphere.

5. The powerful tool for attracting commercial beauty: the giant mirror balls art installation in the atrium of shopping centers often becomes a hot spot for check-in. With different festival themes (Valentine's Day, Mid-Autumn Festival), the color and lighting design of the mirror balls will also change accordingly, and continue to attract customers.

How to install the mirror balls in different places?

1. Stick on the wall: usually using a "traceless adhesive base". First, fix a transparent acrylic bracket on the wall that matches the curvature of the mirror balls, and then bond the mirror balls to the bracket with structural adhesive to achieve a visual suspension effect.

2. Standing on the ground: For small and medium-sized spheres, "buried installation" is often used. Customize a metal or stone base with grooves, embed the sphere into the grooves and secure it. For large-sized spheres, it is necessary to ensure that the base is stable enough to prevent overturning. Alternatively, you can simply cut off a small piece from one end to create a flat surface and place it directly in place. This is the safest and simplest option, but the downside is that you cannot see a complete circular sphere.

3. Hanging in the air: The weight of the large-sized mirror balls is astonishing, and safe suspension is the biggest challenge. Multiple point clamps must be used to support the bottom of the sphere, and the suspension cable must be firmly connected to the building load-bearing beam through expansion screws. If pursuing ultimate visual appeal, high-strength transparent nylon ropes can be used for lifting, creating a magical effect of a sphere floating in the air.
