Provided is a light emitting diode (LED) bulb, comprising a substrate (12), a lamp cup (11), a cover plate (14) and a power connection (13); the lamp cup is a two-piece structure consisting of a light-receiving part (111) and a lamp cup part (112); the substrate (12) is disposed inside the lamp cup (11); the power connection (13) is provided with a power supply driver (133) therein and is connected to the lamp cup (11). When a light emitting source and the power supply driver generate heat, the generated heat is dissipated through the lamp cup or the power connection; because the heat generated by the two heating sources in the bulb can be respectively dissipated, the present invention avoids the co-heat effect caused by the light emitting source and the power supply driver, thus improving the light emitting efficiency and service life of the light emitting source. Furthermore, the whole LED bulb is clamped together, thus saving assembly cost and time. |
