Optical System
• Bulb-related
• Bulb Type: It is clearly stated that a 380W gas discharge bulb is usually adopted, and well-known brands such as Osram may be selected. Gas discharge bulbs are commonly used light sources in stage lighting, featuring high brightness and luminous efficiency.
• Bulb Life: It is approximately 1500 - 2000 hours. However, the actual life will be affected by the usage environment (such as temperature, humidity, dust, etc.) and the frequency of use. For example, in an environment with high temperature, high humidity and more dust, the bulb life may be shortened; and if the usage frequency is too high and the bulb is switched on and off frequently, it will also have an adverse impact on the bulb life.
• Color Temperature: It is generally in the range of 6000K - 7500K. This kind of cold white light is suitable for creating strong beam effects and clear color presentation.
• Beam Angle
• Minimum Beam Angle: It can be narrowed down to 2° - 3°, which can generate very concentrated and powerful beams for long-distance projection and highlighting key areas.
• Zoom Range: It usually has a relatively large zoom range, for example, from 3° to 30° or wider, which can flexibly adjust the diffusion degree of the beam according to the scene requirements, realizing the effect from sharp beams to wide-area lighting.
Mechanical Structure and Motion Performance
• Pan/Tilt Angle
• Horizontal Scanning: 540° or infinite rotation (depending on the specific model and design), which can achieve all-round horizontal coverage and meet the needs of various stage layouts and performance movements.
• Vertical Scanning: It is generally about 270°, which can accurately position the light within a large vertical range, creating rich light and shadow levels and dynamic effects.
• Scanning Precision: High-precision stepper motors or servo motors are mostly used for driving, and the scanning precision can reach 16bit or higher, ensuring smooth movement, accurate positioning, without jitter and noise.
