Method for exciting mixed light emitting of long-afterglow material by electric light source, mixed light luminophor manufactured based on the same and control method thereof

Abstract

The invention discloses a method for exciting mixed light emitting of a long afterglow material by an electric light source. By combining a first long-afterglow luminescent material, a second long-afterglow luminescent material and an excitation light source with mutually matching spectral performance, the excitation light source is powered on to emit light and excite the two long-afterglow materials, the mixed light emitted by the two long-afterglow materials under the excitation of the exciting light presents a color identical or close to the light emitting color of the first long-afterglowluminescent material, the mixed light emitting of the emergent light of the excitation light source and the excited light of the two long-afterglow materials enables the total light emission reaches arequired light emission brightness; after power failure, the two long-afterglow materials can achieve mixed light emitting in the form of afterglow luminescence, the second long-afterglow luminescentmaterial also can excite the luminescence of the first long-afterglow luminescent material and effectively improve the afterglow luminescence brightness of the first long-afterglow luminescent material, so that the total afterglow luminescence brightness is greater than the afterglow luminescence brightness of the first long-afterglow luminescent material, and the luminescent color is the same asor close to that of the first long-afterglow luminescent material. The invention also provides a mixed light luminophor manufactured based on the method and a control method.

Description

technical field [0001] The invention relates to the field of special luminescence, in particular to a method for exciting a long-afterglow material to emit mixed light by an electric light source, a mixed light illuminant manufactured based on the method and a control method thereof. [0002] technical background [0003] Long afterglow luminescent materials are also called luminous materials, which have the function of afterglow luminescence and can be excited by external light sources such as ambient light or lights. Generally, it absorbs light and is excited to emit light during the day or under the light, and glows afterglow at night or in an environment without light. Its products are mainly various signs, signs or coating products, which are widely used in emergency, induction, fire protection, escape, energy saving, etc. in transportation, construction, military and other fields. expand. [0004] The early long-lasting luminescent materials are mainly sulfide system ...

AI Technical Summary

Problems solved by technology

[0018] In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a method for exciting a long-lasting material to emit mixed light by an electric light source and a mixed-light illuminant (especially a red-based mixed-light illuminant) manufactured based on the method. ) and its control method, the method and the products manufactured based on the method have the advantages of large material selection space, wide adaptability of luminous color, high luminous brightness when excited, high afterglow brightness after excitation stops, long afterglow time, partial chromaticity Small shift, good energy saving effect, long service life, etc., can solve the problem of poor luminous performance of existing long-lasting photoelectric devices or equipment and can promote the further development of this industry
