NON-INCENDIARY DISPLAYS

摘要

Non-incendiary displays comprise the use of mainly relatively highly luminous particles emitted as a shower or a cloud from a delivery means or cannon which may include acoustic effects. Unlike fireworks light is generated without an ongoing process of combustion. Strontium aluminate is a preferred luminous material, coated onto confetti-like particles or other shapes of particles which have been designed to hang in the air for a period and may, after excitation, also continue to glow for some hours after falling onto a surface. Colours may be provided by the additional use of fluorescent dyes or reflective surfaces. Laser beams, floodlights, or the like may further enhance the appearance of the display which, like fireworks, is better when seen in the dark. The invention includes the particles themselves whether loose or in packs, delivery means, and display systems.
