Laser light warning protection product

Abstract

The laser luminescent thermal protection is based on functional pigments that are incorporated into the base material or applied by means of a binder to flat materials of all kinds, but preferably to textile fabrics of laser protective equipment for people and rooms or solid walls and devices in the vicinity of lasers, making invisible laser beams visible.

Description

The invention describes a warning light for large-area laser safety products such as personal protective equipment, shields, or even large walls and enclosures that generate visible light (approx. 380–780 nm) when struck by invisible laser radiation (approx. 180–380 nm or 780–11,000 nm). The warning light appears as a luminous effect in different colors, as it depends on the laser beam wavelength, the type and structure of the functional pigments, the duration of the radiation, and the beam power. The luminous effect signals the need for action in the presence of directed and stray laser beams. The user or operator within the operating area of ​​an invisible laser is warned of uncontrolled or unintentional exposure to laser radiation by the light emitted by the material struck by the laser, before the laser safety equipment or shielding is damaged or even penetrated. The invention relates to protection against laser beams of all kinds. This is achieved by functional pigments that are applied to materials of all kinds using a binder or incorporated into a base material. The functional surface can be a flat, flexible, or solid coating or be incorporated into a material. The following laser safety products or products used in the vicinity of a laser can be coated or equipped with this functional material: - Personal protective equipment: Clothing, gloves, helmets and hoods, goggles - Laser safety shielding: Curtains, partitions, booths with and without doors, windows, room walls in the form of paint for buildings - Products and materials used in the vicinity of a laser: Laser optical tables and laser equipment, tables and workbenches, floors, housings of devices and measuring systems Excluded from this are so-called laser light cards, which are used to track a laser beam. These have significantly smaller illuminated areas compared to this invention and therefore cannot fulfill the warning function. The large-area material described in the invention converts invisible, dangerous radiation into visible wavelengths and thus becomes recognizable to the user as a warning. The effect is achieved through a combination of light-sensitive pigments (functional pigments) that convert a wavelength of invisible radiation into visible radiation through physicochemical processes. In this application, an invisible beam strikes a warning light surface. After light conversion, this surface emits light back at a wavelength visible to the human eye. The laser energy required to generate the light is far below the destruction threshold of the materials used. The inventor has sufficient experience and developments in laser safety products, but these are not the subject of this invention. The invention is explained with reference to a drawing. Description of the drawing Fig. 1: A laser-sensitive material or coating (1) on a substrate (2) or even without a substrate is struck by an invisible laser radiation (3) of approximately 180 - 380 nm or approximately 780 - 11000 nm and converts the laser light waves into visible light (380 - 780 nm) (4) that can be perceived by a human eye (5).

Claims
