Application of laser level in stage lighting

With the continuous development of stage lighting technology, laser levels, as a measurement tool that can provide high-precision horizontal lines, are also widely used in the debugging and correction of stage lighting. This article will discuss in detail the principle of the laser level, its application in stage lighting and its advantages and disadvantages.

Working principle of laser level

The laser level uses the laser beam as the measurement reference line, utilizes the linearity, monochromaticity, coherence and other characteristics of the laser beam, receives the laser signal through the photoelectric sensor, and performs signal processing to finally obtain an accurate horizontal line. The main working principle of the laser level can be divided into three steps:

Laser emission. The laser level generates a laser beam through a built-in laser
transmitter, and the laser beam is emitted through a collimating lens or a prism to form a straight beam.

Laser reception. The laser level receives the laser signal through the built-in photoelectric sensor, the sensor converts the laser signal into an electrical signal, and then processes it through the signal processor to finally get the position of the horizontal line.

A horizontal line is displayed. The laser level displays the position of the horizontal line through the built-in display screen or LED indicator to reflect the position of the horizontal plane.

Application of laser level in stage lighting

The application of laser level in stage lighting is mainly reflected in the debugging and correction of lighting. In terms of lighting adjustment, the laser level can provide a high-precision horizontal line for positioning and correction of the light, ensuring the position and angle accuracy of the light; in terms of light correction, the laser level can quickly and accurately measure the inclination angle and horizontal position of the light , used to adjust the angle and position of the light to achieve the best stage effect.

In the specific application, firstly, the laser level needs to be placed in the center of the stage. According to the number and position of the lights to be adjusted, the laser level should be adjusted so that it can cover the entire stage. Then, use the laser level to measure the position and angle of each light, adjust and correct according to the measurement results, and finally realize the precise positioning and angle correction of the light.

Advantages and disadvantages of laser level in stage lighting

advantage:

1. High precision: The laser level can provide extremely high measurement accuracy, reaching 0.1mm/m, to ensure the position and angle accuracy of the light.
2. High efficiency: The laser level can quickly and accurately measure the position and angle of the light, which can be used to quickly debug and correct the light and improve work efficiency.
3. Easy to operate: easy to operate: the digital display of the laser level can intuitively display the measurement results, as well as information such as the direction and angle of adjustment that needs to be made, and the operation is simple and convenient.
4. Wide range of application: The laser level is suitable for different types of stage lighting equipment, including moving headlights, LED lights, beam lights, etc., and can meet the measurement needs of different lighting equipment.

shortcoming:

1. The price is high: the price of the laser level is relatively high, and sometimes additional investment is required to increase the cost of stage lighting equipment.
2. Affected by the environment: In some special environments, such as a lot of dust and insufficient light, the measurement accuracy of the laser level may be affected.
3. High maintenance cost: The laser level needs to be maintained and calibrated regularly to ensure measurement accuracy and accuracy, which increases the maintenance cost and workload of the equipment.

To sum up, the advantages of laser level in stage lighting are high precision, high efficiency, easy operation and wide application range, but there are also disadvantages such as high price, environmental impact and high maintenance cost. When using it, these factors need to be considered comprehensively, and appropriate equipment and operation methods should be selected to ensure the accuracy and effect of stage lighting.
