People who have been to KTV will be attracted by her interior decoration, and in interior decoration, the design of lighting is the key. Lighting is a silent language. It explains the designer's thought with brightness, color, pattern and change. For an excellent KTV interior design project, the quality of lighting design is directly related to the overall effect.

We should use this highlight for exquisite indoor lighting design. When you have been to the beautifully decorated KTV, the well decorated places will leave a deep impression. When installing, you should not only consider her color scene layout and the selection of lamp types, but also consider her installation wiring, circuit direction and switch position. Choosing lamps with good brands can often guarantee the quality and the effect of lighting.

1、 The origin and development of KTV
（1） Understand the origin of KTV. She originated in Japan and developed from the walking and singing band of several people in small pubs to today's karaoke. "Karaoke" means "empty" in Japanese, and "OK" means the first two words of English "Orchestra Symphony Orchestra". The Japanese made words to combine these two words into "karaoke", which means no one band, After several years of evolution, it was later spread to Taiwan and installed karaoke in the room. It was named KTV, "K" was the first word of karaoke and "TV" was the last two words of MTV (Music TV).
（2） The development process in recent years. In the 1990s, karaoke was the most popular time, but it also underwent a series of evolution. In the early days, I saw someone pushing a karaoke for mobile business, which was very similar to the situation when Japan launched karaoke at the beginning. Later, following the example of Japan, the venue design changed from open to box. In recent years, family karaoke machines have been shelved, and the karaoke hall in the city has developed into mass selling. Now there are no large KTVs with high prices. Instead, KTV chains or mass sellers such as Taiwan cash counters and Shanghai haoledi. The sound equipment is good. We eat, drink and have fun together. Different consumption patterns lead to different services.

2、 Lamps
The design of KTV lighting should be divided into three parts: artistic lighting, conventional lighting and emergency lighting. Art lighting is a color based lighting design for decoration; Conventional lighting is normal room lighting dominated by brightness; Emergency lighting is a lighting design that is automatically started by the battery in case of emergency. The lighting design should take energy conservation and environmental protection as the central idea, be simple and bright, and do not produce glare.
The design of KTV lighting should closely combine artistry and technology, take into account the effect and atmosphere, and give people a colorful feeling. This feeling can only be given by light. First, we need to know about lamps.
（1） Understand the classification of lamps
According to the installation method, it can be generally divided into six types: ceiling lamp, chandelier, wall lamp, movable lamp, architectural lighting, etc; According to the light source, it can be divided into incandescent lamp, fluorescent lamp, etc; According to the place of use, it can be divided into civil lights, architectural lights, stage lights, etc; According to the light distribution and severe cold, it can be divided into direct lighting type, semi direct lighting type, full diffuse lighting type and indirect lighting type.
（2） Clear principles for selecting lamps
1. The principle of simplicity, lighting should be the finishing touch in the room. Too complex shapes and too complicated colors are not suitable for designing simple rooms.
2. According to the principle of convenience, most people have experienced the embarrassment of replacing the ceiling lamp bulb: stepping on the table, stepping on the chair, holding your head up 90 degrees, and raising your arms to the ceiling 2.5m high or even higher. When selecting lamps, the convenience of changing bulbs must be considered.
3. Safety principle: lamps from regular manufacturers must be selected. Regular products are marked with total load. According to the total load, you can determine how many watts of bulbs to use, especially for multi head chandeliers. In addition, waterproof lamps should be selected for toilets and kitchens with high moisture.
（3） Focus on understanding LED lights
LED lamp is a semiconductor solid-state light-emitting device. It uses solid-state semiconductor chip as light-emitting material. When a forward voltage is applied at both ends, the carriers in the semiconductor recombine and cause photon emission to produce light. LED can directly emit red, yellow, blue, green, green, orange, purple and white light.
The characteristics of LED lamp are: changeable and illusory: the LED light source can realize multiple changes of color and pattern under the control of computer technology by using the principle of short led pass time and three primary colors of red, green and blue. It is a "dynamic light source" that can be controlled at will; Long service life: the LED light source has no filament and low working voltage. The service life can reach 50000 to 100000 hours, that is, 5 to 10 years; Environmental protection: no harmful elements in production and no harmful substances in use.

3、 Selection and application of KTV lamps
（1） Selection of decorative materials. In the indoor lighting design of KTV, the general types of lamps to be used are: spotlight, downlight, chandelier, wall lamp, LED lamp and so on. Each of these lamps can create a different atmosphere effect. Spotlight can gather a beam of light together to illuminate a certain area. The gathering of multiple beams of light will create a different atmosphere effect. Downlight, the simplest thing is to play the role of conventional lighting. Of course, it can also be combined with several groups of lamps to create a gorgeous effect. Chandeliers often give people the feeling of luxury, but now some chandeliers also have a modern sense. They are matched with metal and glass, and their texture is integrated with the matching of private rooms. The most common is led lamp. The dynamic change, color diversity and lasting brightness of LED lamp are used in KTV interior decoration.

（2） Construction, installation and maintenance of lighting. During interior decoration, priority shall be given to the wiring of lamps, and corresponding pipelines and power sockets shall be reserved for each lamp. In KTV, there are usually dozens or even hundreds of lamps with different purposes and different effects. If each lamp is controlled by an independent switch, although it can increase the flexibility of control and the patterns of different lamp combinations, so as to derive more rich and diverse lighting effects, it not only increases the installation cost, Moreover, it greatly increases the complexity of operation and use, and the gain is not worth the loss. Therefore, in the design, various lamps in the song and dance hall should be classified and grouped first. After installation, the light shall be debugged to adjust the brightness and tone of the light according to the environment and the desired atmosphere effect.

4、 Summary
Using lights to decorate the indoor space of KTV is a re creation of beauty. The lighting design of KTV should be selectively shaped according to different styles. The lighting design of KTV entrance and private room is the top priority. The design of population can establish a good corporate image and make people feel good as soon as they come in. The private room is a place for customers to entertain, and the time in it is the longest. Of course, the lights in the private room should not be too gorgeous to avoid customers' eye fatigue. The lighting of the walkway should not only consider the decoration, but also consider the safety, and should not be too dim. Therefore, when decorating KTV, we should pay attention to the lighting design, use colorful interior lighting design to attract customers and stand out from many KTV.
