Abstract

The invention belongs to the field of optical technology, and in particular relates to a fluorescent glass material, a preparation method thereof, a lampshade and a lamp. The invention provides a kind of fluorescent glass material, the chemical composition of fluorescent glass material is (P 2 o 5 ) 0.56 (B 2 o 3 ) 0.15 (Al 2 o 3 ) 0.20 (ZnF 2 ) 0.10 (MnO) x ; where, 0.01≤x≤0.025. The fluorescent glass material of the present invention can emit white light under the excitation of the excitation light source, and the emitted white light is obtained by mixing blue-violet light with a peak value of about 410nm and yellow light with a peak value of 520nm and 580nm. Compared with traditional fluorescent powder, the fluorescent glass material of the present invention , has better thermal stability, avoids the problem of uneven dispersion of phosphor powder in organic resin, reduces the loss caused by light scattering, and the production cost of the fluorescent glass material of the present invention is low, simple to prepare, and convenient Processed into various shapes, suitable for mass production.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a fluorescent glass material, a preparation method thereof, a lampshade and a lamp. Background technique [0002] Currently, the mainstream lighting methods are white light emitting diodes (White Light Emitting Diode, WLED) and fluorescent lamps. There are two main ways for WLEDs to achieve white light. The first one uses multi-chip WLEDs, which mix red, green and blue monochromatic LED chips to produce the target white light; the second one uses phosphor powder to convert WLEDs to excite yellow through blue LED chips. Phosphor powder or ultraviolet LED chips are used to excite three primary color phosphors to mix target white light. [0003] Multi-chip WLEDs can achieve high luminous efficiency, and there is no aging related to phosphors and poor pink color when packaged. However, different LED chips require different driving circuits, which are complicated in stru...
