S/P SMT LED LIGHT SOURCE WITH IMPROVED S/P RATIO

摘要

The present invention relates to a surface mount type LED light source, and more particularly, to a surface mount type LED light source, in which a blue LED chip and a yellow phosphor are mixed to form a white light source, Technology LED), a green phosphor is mixed with a transparent silicon to form an additional molding portion. The additional molding portion is wrapped around each basic molding portion to increase the wavelength of the green region. Then, a red LED chip It is possible to improve the S / P ratio while using the conventional surface mount type LED by implementing the distortion free white color, thereby improving the S / P ratio, which enables the user to visually feel brighter while consuming the same power. Mounted type LED light source.
