Abstract

The invention discloses a long-persistence fluorescent source and a preparation method thereof. The fluorescent source comprises a base material (4) and a carrier (3) arranged on the base material (4). A fluorescent slurry layer (2) is arranged in the carrier (3). The long-persistence fluorescent source is characterized in that: a reflecting layer (5) is encapsulated on the carrier (3) in which the fluorescent slurry layer (2) is arranged so as to form the bottom luminescence type fluorescent source. The method comprises the following steps of: 1), selecting materials; 2), preparing an intermediate carrier; 3), preparing a slurry of the fluorescent slurry layer (2); 4), preparing a slurry of the reflecting layer (5); 5), printing the slurry of the fluorescent slurry layer (2); and 6), printing the slurry of the reflecting layer (5) to obtain the bottom luminescence type fluorescent source. The fluorescent source has the advantages of radiation resistance, long service life, energy conservation, environmental friendliness and wide application range.

Description

technical field [0001] The invention relates to a device capable of providing illumination at night, in particular to a printed long-lasting fluorescent light source and a preparation method thereof. Background technique [0002] Existing light sources such as figure 1 As shown, a traditional fluorescent light source device includes a substrate 4 and a light-emitting element mounted on the substrate 4, the light-emitting element is a phosphor particle 2 arranged on a carrier 3, and an encapsulation layer is encapsulated on the carrier 3 1, thus forming a top-emitting fluorescent light source. The reflective layer 5 of the top-emitting fluorescent light source is located between the base material 4 and the light-emitting layer, so that this kind of light source has many manufacturing steps and increases the production cost. [0003] Long afterglow phosphor (commonly known as luminous powder) is a new type of energy that can receive natural light (sunlight) and various light...
