This disclosure is related to a surface light source LED device which comprises a circuit board, at least one power input and at least two LED Bar assembly components, wherein the at least two LED Bar assembly components are arranged in a staggered manner and each LED Bar assembly component consists of a plurality of LED Bars arranged linearly on the circuit board, further each LED Bar has a straight strip structure and is provided with a plurality of LED dies of the same type inside. The plurality of LED die are arranged linearly at equal intervals. This disclosure can effectively solve the problem that the design of the heat sink is complicated or the size is too large due to excessive energy consumption, further it can also improve the problem that the existing lamps with LED as the light source will have uneven surface light source, uneven brightness. Meanwhile, this disclosure achieve a large surface light source area with a less number of LEDs, this disclosure also has the high quality of the lamp body,
