Light emitting diode device

Abstract

An LED device has an LED mounted on a substrate, and a transparent resin including phosphor particles for changing a color of light emitted from the LED, and sealing the LED. The transparent resin is colored by a dye at least on the surface. The dye is for correcting the changed color to a desired color.

What is claimed is:  
     
         1 . An LED device comprising: 
 an LED mounted on a substrate;    a transparent resin including phosphor particles for changing a color of light emitted from the LED, and sealing the LED; and    a dye dyeing the sealing resin for correcting the color of the light from the LED.    
     
     
         2 . The device according to  claim 1  wherein the dye has a color for correcting the color of the light from the LED to acquiring a desired color of light.  
     
     
         3 . The device according to  claim 1  wherein the dye has a complementary color to the color of the light emitted from the LED for a desired color.  
     
     
         4 . The device according to  claim 1  wherein at least a surface of the sealing resin is dyed by the dye.  
     
     
         5 . A method for manufacturing an LED device comprising the steps of: 
 mounting an LED on a substrate;    sealing the LED with a transparent resin including phosphor particles to form an LED device before being dyed;    measuring chromaticity of light from the LED device before being dyed;    dyeing the sealing resin by a dye having a color for correcting the measured chromaticity to a desired color.    
     
     
         6 . The method according to  claim 5  wherein dyeing of the transparent resin is controlled by at least one condition selected from the concentration of the dye, the temperature of a liquid in which a dye is put, and the time in soaking the LED device before being dyed in the liquid containing the dye.
