Step 5, paste one layer of saturating face resin in described glue layer, that is, obtain described luminescent film finished product.
It is 20mcd/m as form 1 summarizes embodiment 1～4 in intensity of illumination2It is luminous that lower Continuous irradiation 10min obtains
The luminous intensity of film：
Can draw, the luminescent material poor waterproof properties that this case provides, when being not coated by waterproof layer in luminescent material periphery, institute
The luminous intensity of prepared luminescent film is low, and luminous persistence is short.After applying waterproof layer around luminescent material, it is obtained and sends out
In the luminous intensity of light film and fluorescent lifetime and luminescent layer, contained luminescent material ratio is relevant, when shared by the quality of luminescent material
When the ratio of photosphere is 20%, the luminous intensity of its luminescent film is 6mcd/m2, fluorescent lifetime is 20min, with luminescent material institute
The increase of accounting example, the luminous intensity of luminescent film strengthens, and fluorescent lifetime extends, when proportion 50%, luminescent film luminous
Intensity reaches maximum, and fluorescent lifetime is the longest, increases with luminescent material proportion afterwards, and the luminous intensity of luminescent film diminishes, and sends out
Shorten between the light time.
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in description and embodiment
With, it can be applied to various suitable the field of the invention completely, for those skilled in the art, can be easily
Realize other modification, therefore under the general concept being limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
