LED bulb easy to assemble

The invention discloses an LED bulb easy to assemble. The LED bulb comprises a lamp cap, a lamp housing, a driving plate, a radiator, an LED light source plate and a lampshade. The lamp cap is fixedly connected with the lamp housing, clamp grooves are formed in the lamp housing, the driving plate is clamped in the clamp grooves of the lamp housing, and a pin which is used for being electrically connected with the LED light source plate is arranged at the end, which is far away from the lamp cap, of the driving plate; the radiator is clamped on the inner wall of the lamp housing and is provided with an end surface which is far away from the lamp cap, a yielding hole is formed in the end surface of the radiator, the LED light source plate is fixedly connected onto the end surface of the radiator, an electric connector is arranged on the LED light source plate and penetrates the yielding hole to be connected with the pin of the driving plate in a plugged manner, or the pin of the driving plate penetrates the yielding hole to be connected onto the electric connector in a plugged manner, or the electric connector and the pin of the driving plate simultaneously extend into the yielding hole and are connected with each other in a plugged manner; the lampshade is clamped on the lamp housing; a gland is further clamped with the lamp housing and presses the radiator, and a light guide column is clamped in the middle of the gland. The LED bulb has the advantages of easiness in assembling, high production efficiency, good product specification and suitability for automatic production.
