Abstract
An LED package assembly comprising two or more light emitting diode dies within an epoxy housing such that a wider light emitting angle with a higher light intensity everywhere around the package including its bottom part is obtained. The LED package can be a substitute for bulb illumination or serving some decorative functions. Furthermore, the LED has low power consumption, a tough body and a long working life. Moreover, a cluster of these LEDs in a large display screen is capable of enhancing clarity of vision and the range of observation from a few meters to a few kilometers away.
