FANCY REDUCING COATINGS FOR LED LIGHTING MODULES

Description of the project: The method for preparing light-converting coatings includes joint grinding of low-melting glass and phosphor (YAG: Ce3 +) powders, and subsequent preparation of a slip from finely ground glass powder with a phosphor and an organic polymer. Light-converting coatings were obtained on sheet glass substrates at an application temperature of 600–640 ° C.

Characteristics of fusible glass.

Synthesis temperature – 950–100
0 ºС Full spreading temperature – 540–600
ºС Temperature coefficient of linear expansion – (92–94) 107 K
– 1 Refractive index – 1.725

Advantages: The developed light-converting coatings are tested as an element of a luminaire layout with a remote light-converter. It was found that the emission spectrum of the device corresponds to quasi-white light when using high-power blue LEDs.
