激光产品的安全性.第3部分:激光显示器和显示指南

[中文适用范围]： IEC 60825 的这一部分是一份技术报告，为利用高功率激光器的激光显示器和演示的规划和设计、设置和实施提供了指导。在剧院、竞技场或建筑场所等大空间中进行有效的戏剧或艺术展示所需的激光功率足够大，足以造成严重的意外暴露危险，即使个人暴露时间非常短暂。因此，IEC/TR 60825-14 第 4.1.5 条规定，只有 1 类、2 类或可见光束 3R 类激光产品才应用于无人监管区域的演示、展示或娱乐目的。其他类别的激光产品只能在严格控制的条件下并在经过培训的经验丰富的操作员的控制下才允许使用。本技术报告中提供的指南无意包括科学、医疗或工业激光产品的展示或演示。然而，本指南中的许多原则可能是相关的。本指南为那些用于展示光学原理的激光显示器或演示、艺术展示、广告或光雕塑或博物馆作品等提供安全建议。可在家庭环境中使用或供以下人员使用的激光产品不能预期已接受过适当级别的培训应为 1 级、2 级或可见光束 3R 级。因此，此类设备不在本指南的范围内。 [外文原描述]： This part of IEC 60825, which is a technical report, gives guidance on the planning and design, set-up and conduct of laser displays and shows that make use of high power lasers. The laser power needed to produce effective theatrical or artistic displays in large spaces such as theatres, arenas, or architectural sites is great enough to pose a severe accidental exposure hazard, even when personal exposure is very brief. For this reason, subclause 4.1.5 of IEC/TR 60825-14 specifies that only laser products that are Class 1, Class 2 or visible-beam Class 3R should be used for demonstration, display or entertainment purposes in unsupervised areas. Laser products of other classes should only be permitted under carefully controlled conditions and under the control of a trained experienced operator. The guidance provided in this technical report is not intended to include the display or demonstration of scientific, medical or industrial laser products. However, many of the principles in this guidance may be relevant. This guidance provides recommendations for safety for those laser displays or demonstrations that are shows, artistic displays, advertising or light sculptures, or museum pieces used to demonstrate optical principles, etc. Laser products available for use in a domestic environment or for use by people who cannot be expected to have received a suitable level of training should be Class 1, Class 2 or visible beam Class 3R. Therefore, such equipment is outside the scope of this guidance. This guidance is intended to be used by those who: - design, manufacture, assemble, install or operate laser products that are Class 4, Class 3B, or non-visible beam Class 3R for display and entertainment purposes; - operate arenas, theatres, planetaria, discotheques or other places where such laser products may be installed and operated; or - are responsible for reviewing the safety of such equipment, installations or displays. This guidance is not normative, but rather a code of practice for the design, installation, operation and evaluation of the safety of laser light shows and displays, and the equipment employed in their production. This guidance is also intended for persons who modify laser display installations or equipment. This guidance contains safety criteria for the protection of the public or persons in the vicinity of laser displays in the course of their employment. In some countries, there may be specific requirements, such as government permissions or notifications of shows, or prohibitions, such as against laser scanning of spectators without appropriate safeguards. This guidance is not to be understood as in conflict with such requirements but merely to be supplementary. This second edition cancels and replaces the first edition published in 1995. It constitutes a technical revision. The main changes since the first edition include - clarification of the scope; - specific guidance on factors to take into account regarding scanning safeguards; - clarification of the records to be maintained; and - modification of the requirements for the zones where unattended laser projectors are used.
