(1), fluorescent material mixed the back stir with glue, form the mixture of uniform fluorescent material and glue;
(2), the inner surface that adheres to the optics of fluorescent material to needs cleans up, and with its outer surface protection good seal, is placed in the sealing spray chamber;
(3), with the atomizing of the mixture of fluorescent material and glue, then the fog of atomizing is sent in the above-mentioned sealing spray chamber;
(4), the fog of the mixture of fluorescent material in the above-mentioned sealing spray chamber and glue is attached on the inner surface of above-mentioned optics;
(5), the optics that will be attached with the mixture of fluorescent material and glue takes out and carries out solid glue from the sealing spray chamber, processes required remote fluorescence powder optics.
The inner surface that adheres to the optics of fluorescent material to needs in the step (2) cleans up, and uses frock or diaphragm with its outer surface protection good seal, is placed in the sealing spray chamber.
Mixture with fluorescent material and glue in the step (3) atomizes through vibration of ultrasonic wave atomizing or gases at high pressure spray gun, sends to then in the described sealing spray chamber of step (2).
The fog that the method for use natural subsidence or Electrostatic Absorption will seal in the spray chamber in the step (4) is attached on the inner surface of optics.
Said fluorescent material selects for use diameter less than 20 microns spherical particle fluorescent material; Said glue is selected transparent antiultraviolet glue for use.Fluorescent material mixes with glue will guarantee when stirring that fluorescent material is even in glue.
The optics that need adhere to fluorescent material can be brand-new customization device, also can use original optics to carry out upgrading through the said method step and be remote fluorescence powder optics.
Above-mentioned optics can have the different shape surface, the fluorescent material after the atomizing and the mixture of glue evenly is attached to the different shape surface, thereby prepares difform remote fluorescence powder optics.
The fluorescent material painting method of remote fluorescence powder optics of the present invention has the following advantages:
1, adopts remote fluorescence powder attachment techniques can reduce, reduce the processing technology difficulty, increase the versatility of remote fluorescence powder technology thereby reduce cost to the raw-material restriction of plastic optical component;
2, adopt remote fluorescence powder attachment techniques can reduce the indirect processes influence to fluorescent material, whole process does not have thermal shock and mechanical stamping to fluorescent material, can improve yields;
3, adopt remote fluorescence powder attachment techniques to upgrade to existing traditional optical device, compatible multiple molded device makes that new technology can good transition;
4, remote fluorescence powder attachment techniques attached to the device inner surface, makes fluorescent material be protected in fluorescent material, improves the life-span of optics;
5, preparation technology is simple, is applicable to existing multiple light transmissive material, simplifies the harsh requirement of conventional method to plastic material, can adapt to difform surface, thereby, have good value for applications.
