Description

Integrated LED packaging device Technical Field The present invention relates to an integrated LED package device, and more particularly, to an integrated LED package device in which an LED, a driver for controlling the same, and a memory storing information of a color temperature range of the LED are integrated into one chip form. Background LEDs are widely used as effective light emitting devices for electronic devices, and are used in various fields such as lighting, displays, and signal lamps. The LEDs have the advantages of low power consumption, long service life and the like, and the required current and voltage values can be different according to the characteristics of each LED. Thus, a system using a plurality of LEDs needs to set a current individually in consideration of characteristics of each LED, but there are various difficulties in design and implementation thereof. In particular, when a plurality of LEDs are to be connected to the same circuit or controlled in the same package, since the intrinsic characteristics (color temperature range information) of the respective LEDs are different, there is a disadvantage in that it is necessary to individually set a suitable current value for the respective LEDs. The color temperature range information means data for determining optimal current, voltage, color, brightness and the like required for each LED to emit light. However, the conventional technology requires to separately manage color temperature range information of each LED and control current based on the information, and thus, it is required to separately layout control circuits and settings according to different LEDs, and thus, it has drawbacks in that design is complicated and it is required to perform a plurality of wiring works. In addition, when color temperature range information of each LED is stored in another external memory or a control device, communication or additional wiring is required to be performed with the external device in order to appropriately control the current according to the information, and thus, there is a disadvantage in that the size or complexity of the system is increased, and additional costs and time are consumed to achieve optimal control. Therefore, the conventional LED system has problems that the realization of the color temperature range information management and the individual control of each LED causes the problems of complicated circuit structure, increased wiring, reduced system efficiency, and the like. In view of this, there is a need to develop a novel LED package device of monolithic shape that integrates a memory and a control circuit that have stored therein LED color temperature range information in advance.
