一個好的ktv設計效果圖離不開完美的燈光設計，而燈具投光范圍在燈光設計可達到完美的陪襯效果，那么ktv燈光設計怎樣選擇合適的投光范圍?
A good KTV design effect diagram can not be separated from the perfect lighting design, and the light range of the lamp in the lighting design can achieve a perfect foil effect, then KTV lighting design how to choose the appropriate range of light?
投光范圍就是指燈具所提供的標準照度范圍的大小，它決定于人們的活動范圍和被照物體的體積及面積等。如餐桌所需的投光范圍就是餐桌的面積;乒乓球臺所需的投光范圍就是球桌的面積;壁畫則應使光線照射到整個畫面;起居室內休息、待客的地方，則應使光線照射到整個沙發座位。有些時候為了強調景物中某些位置，比如畫面的某一點，雕塑的某個局部，則可增設專用燈具，以取得預期效果。

The light range refers to the size of the standard illuminance range provided by the luminaire. It depends on the range of motion and the volume and area of the object being illuminated. If the table required light range is the table area; table tennis table needed to cast light range table is the area; mural should be light to the entire screen; the living room to rest, the local hospitality, should be light to the sofa seat. Sometimes, in order to emphasize some places in the scene, such as a certain point of the picture, a part of the sculpture can be added with special lamps to achieve the desired effect.
在KTV設計裝修中，投光范圍是一個相當重要的問題。如大型的會議室、辦公室和教室等，由于需要均勻的光線，其投光范圍亦是均勻的。但是更多的空間則常需要通過燈具的布置來控制投光的范圍，使室內光線形成一定的明暗對比。
In the KTV design and decoration, the light range is a very important issue. For large conference rooms, offices and classrooms, the light range is uniform due to the need for uniform light. However, more space is often required to control the range of light distribution through the arrangement of lamps, so that the indoor light to form a certain brightness contrast.
分成明暗不同的區域。例如，在劇院中燈光的投射范圍都集中在舞臺上，有時還采用專用燈具，使光線隨著演員在舞臺上的活動而移動其投光范圍，以此來烘托表演的氣氛，并把觀眾的注意力集中到舞臺上以增強演出效果。
Divide into areas of light and shade. For example, in the light projection range in the theatre are focused on the stage, sometimes using special lamps, the light with the actors on the stage of the activities of the mobile light range, in order to express the atmosphere of the performance, and the audience's attention to the stage to enhance performance.
相反，如果把燈具的光線都集中到觀眾廳的范圍，那不僅會分散觀眾的注意力，而且還會沖淡甚至破壞舞臺的照明，進而影響表演效果。
On the contrary, if the light of the lamp is concentrated in the auditorium, it will not only distract the attention of the audience, but also weaken or even destroy the lighting of the stage, thus affecting the performance.
