The present invention relates to a lamp ballast having multiple printed circuit boards (PCB). Particularly, the present invention relates to a lamp having a plurality of a printed circuit boards capable of increasing space use efficiency and minimizing heat transmission from a light source according to the operation of a lamp. According to an embodiment of the present invention, lamp ballast circuit elements are individually separated on the PCBs by different functions. Thereby, heat transmission from the light source according to the operation of the lamp can be minimized. Also, each of the lamp ballast circuit elements arranged on the PCB is separated to become each unit which operates independently. Therefore, a product manufacturing process can be simplified. Moreover, the inspection process of the product can be simplified. |
