An LED light bulb, successively including a light distribution module (11), a light source module (12), a heat dissipation module (13) and an electricity connection device (15). The light distribution module (11) and the light source module (12) are fixed each other, the heat dissipation module (13) includes a hollow structural member formed by more than one metal plate, the electricity connection device (15) is located at the top of the heat dissipation module (13), and the light distribution module (11) is located at the bottom of the heat dissipation module (13), and the light source module (12) is fixed at the inner end of the light distribution module (11). Concave and convex structures of a strip shape are arranged on the outer side wall of the heat dissipation module (13). The LED light bulb connects the utility power to a switching power supply (142) via the electricity connection device (15) and then adjusts the work parameter required by the light source module (12), the heat is dissipated through a dual channel of the heat dissipation module (13), and the light distribution module (11) is used to adjust the lighting required in households, business and industries. The LED light bulb can be used for assembling a lamp socket with IEC standards and can exchange the heat generated by the LED light source with the outside promptly, which makes the cost of the product lower, and performance better, thereby prolonging the service life of the product. |
