| titleOfInvention | LED package with adjustable color temperature |
| abstract | The present invention accommodates two or more LED chips in one reflecting cup of the package body and adjusts the amount of current supplied to each LED chip to enable color temperature adjustment, thereby increasing color mixing efficiency, simplifying structure, and reducing cost. And it can be miniaturized and relates to an LED package capable of color temperature adjustment that can easily implement the emotional lighting. Color temperature adjustable LED package according to the present invention, the package body is formed with one reflection cup; A first LED chip accommodated in the reflective cup; A second LED chip accommodated in the reflecting cup and formed in the vicinity of the first LED chip; A phosphor formed on the first LED chip and the second LED chip; And a current controller configured to adjust each color temperature by varying a current supplied to at least one of the first and second LED chips. Preferably, the first LED chip is a red series, and the second LED chip is a blue series. The phosphor is a single kind of phosphor, and it is preferable that it is a yellow phosphor. The phosphor is preferably an phosphor of one of the yttrium phosphors, aluminum phosphors, garnet phosphors, nitride phosphors, verylene derivatives, zinc selenide phosphors and silicate phosphors, or a combination of two or more phosphors. Two or more of the first LED chip and the second LED chip may be provided in parallel, respectively. An electrode pattern layer and an insulating layer are formed on the bottom surface of the first LED chip and the second LED chip, respectively. |
