What is switchable (smart) film?
Switchable film, also known as smart film, is a specialized material that can change its transparency from opaque to clear when an electrical current is applied. This film is typically composed of multiple layers of conductive polymer materials, such as liquid crystal molecules or electrochromic materials. The switchable film is designed to be applied to glass surfaces, including windows, glass partitions, skylights, and display cases. It offers a versatile solution for privacy control, sun control, and display purposes. Here's a breakdown of how switchable film works: Opaque State: When the electric current is turned off, the switchable film remains in its opaque state. The liquid crystal molecules or electrochromic materials within the film are randomly oriented, scattering light and making it difficult to see through. In this state, the film provides privacy, blocking the view from both sides of the glass. Transparent State: When an electric current is applied...
What is Dolby Atmos in home theater system?
Dolby Atmos is an advanced audio technology developed by Dolby Laboratories that provides an immersive sound experience for home theater systems. It was initially introduced for commercial cinemas and has since been adapted for home use. Traditional surround sound systems use channels to deliver audio, such as 5.1 or 7.1 setups, where the numbers refer to the number of speakers and the ".1" denotes a subwoofer channel for low-frequency effects. Dolby Atmos, on the other hand, goes beyond the channel-based approach and introduces object-based audio. In Dolby Atmos, sound is treated as individual objects rather than being tied to specific channels. These audio objects can be precisely placed and moved in a three-dimensional space, including overhead, to create a more realistic and immersive soundstage. This means that sound can come from above, around, and even below the listener, resulting in a more accurate representation of how sound occurs in...
What is PET acoustic material?
PET acoustic material refers to a type of sound-absorbing material made from polyethylene terephthalate (PET). PET is a thermoplastic polymer commonly used in the manufacturing of various products, including plastic bottles and packaging materials. However, when PET is processed and treated in a specific manner, it can be transformed into an effective acoustic material with sound-absorbing properties. PET acoustic material is engineered to absorb sound waves, reducing noise and reverberation in a given space. It is commonly used in applications where sound control and acoustic performance are important, such as in architectural and interior design projects, auditoriums, theaters, recording studios, offices, and public spaces. The manufacturing process typically involves recycling PET bottles and other PET waste materials. The PET is shredded into small flakes, melted, and then processed into a fibrous material. The resulting PET fibers are compressed and formed into panels, tiles, or other shapes that can be...
How distributed sound system differs from live sound system?
A distributed sound system and a live sound system are two different approaches to audio reinforcement, designed for different purposes and environments. Purpose and Environment Distributed Sound System: A distributed sound system is typically used in commercial or public spaces such as airports, shopping malls, offices, hotels, or restaurants. The primary goal is to evenly distribute sound throughout the entire area, providing background music or making announcements. Live Sound System: A live sound system is employed in venues where live performances take place, such as concerts, festivals, theaters, or clubs. It aims to deliver high-quality, immersive sound to the audience, enhancing the live experience. Sound Reinforcement Approach Distributed Sound System: In a distributed sound system, multiple speakers are installed throughout the space, strategically placed to provide consistent audio coverage. These systems often employ smaller speakers that are evenly distributed to ensure uniform sound levels and intelligibility across the entire...

Light vs pigment color mixture
The knowledge of additive and subtractive color mixing is essential in various fields, including graphic design, digital media, printing, photography, and fine arts. By understanding how colors combine and interact, you can create accurate and desired color results in your work. Additive Color Mixing (Light) Additive color mixing refers to the process of combining different colors of light. This is the method used in electronic displays, such as computer monitors and televisions. In additive color mixing, the primary colors are red, green, and blue (RGB). By varying the intensity of these primary colors, different shades and hues can be created. When red, green, and blue light are combined at their maximum intensities, they produce white light. By adjusting the intensity of each color, you can create a wide range of colors. For example, mixing red and green light at equal intensity produces yellow light. Mixing different combinations of the...
What is IVL lighting?
IVL stands for "Induction Vapor Lamp," which is a type of lighting technology that combines elements of both induction and vapor lamp technologies. IVL lighting is often used for outdoor lighting applications, such as street lighting, parking lots, and large area illumination. IVL lamps operate through a combination of electromagnetic induction and the ionization of gases inside the lamp. The lamp contains a tightly wound coil that produces a high-frequency magnetic field. This magnetic field induces a current in the mercury vapor inside the lamp, causing the vapor to emit ultraviolet (UV) radiation. The UV radiation emitted by the mercury vapor excites phosphor coatings on the inner surface of the lamp, converting the UV radiation into visible light. This process produces a bright and efficient light output. IVL lighting typically provides a white light with a color temperature similar to daylight, enhancing visibility and color rendering. One of the...
