Abstract

The invention relates to a portable lighting device and a using method. The invention belongs to the technical field of lighting equipment, the lighting device comprises a lighting source, a directionregulator and a finger fixator. The illumination light source is used for emitting light beams to illuminate an object for cleaning. The direction adjuster is used for adjusting and fixing the emission angle and the emission direction of the illumination light source. The finger fixer is used for fixing the portable lighting device on the finger of an operator; according to the invention, the lighting requirement is met; an optical element can be synchronously cleaned by a single person with one hand; the manpower demand is reduced, meanwhile, the emission angle and the emission direction ofthe illumination light source can be flexibly adjusted and fixed by adopting the direction adjuster; the optical element is irradiated in a swept incidence mode, dust particles on the surface of the optical element are clearly identified, then the optical element is accurately and rapidly cleaned, the structure is simple, implementation is easy, stability is good, working efficiency is high, and the using requirements for cleaning of the large-caliber optical element and the like are met.

Description

technical field [0001] The invention belongs to the technical field of lighting equipment, and in particular relates to a portable lighting device and a using method. Background technique [0002] The ultra-strong laser output capability of high-power laser devices depends on a large number and variety of large-aperture optical components. Taking the NIF laser device as an example, the whole device contains a total of 7360 large-aperture optical elements (0.5-1.0 meters). The operation and use of high-power laser devices has very high requirements on the surface cleanliness of optical components. During laser emission, the main laser light or stray light is irradiated on the optical components, which may generate a large amount of aerosol and particle pollutants, and the aerosol and particle pollutants may adhere to the optical components. When the intense laser interacts with the particle contaminants on the surface of the optical element, it will cause thermal damage, se...
