Document Type and Number:
Japanese Patent JP7362132
Kind Code:
B2
Abstract:
The present invention relates to method for producing LED by one step film lamination. The method comprises: laminating two or more LEDs with two or more colored phosphor films by one step film lamination; wherein each of the colored phosphor film comprises each other different colored phosphor composition which has a Maximum tan δ; and the difference of each Maximum tan δ varies within a range of 0-30%. In the present invention, the method for producing a LED may greatly improve production efficiency (i.e., dual and multi-color LEDs in one step) and lower cost of ownership. Further, it may improve uniformity of phosphor dispersion, thereby improve color quality of LEDs.
