Although the LED bulb in the prior art can meet the use requirements under the general condition, the heat dissipation performance of the LED bulb is limited, the service life of the LED bulb is influenced, and therefore the applicability and the practicability are limited.
Disclosure of Invention
The utility model aims at providing a structure sets up reasonable and the suitability is strong LED bulb.
Realize the technical scheme of the utility model is a LED bulb, including lamp holder, driver, lamp holder converter, radiator, LED light source and lamp shade. The driver is arranged in the lamp cap, the lamp cap converter is connected between the lamp cap and the radiator, and the LED light source and the lampshade are fixed on the radiator. The radiator is in a hollow cylindrical shape with the top part being semi-closed, radiating fins are integrally formed on the outer wall of the radiator, and radiating through holes are respectively formed in the bottom and the top of the radiator. The lamp shade is in a hollow cylindrical shape with the top end being semi-closed, the top of the transparent lamp shade is provided with a heat dissipation through hole, and the bottom of the transparent lamp shade is sleeved on the heat dissipation fin of the radiator to form a groove-shaped heat dissipation through hole.
The height of the radiating fins is 1-3 mm.
The radiator is an aluminum material body.
The utility model discloses has positive effect: the structure of the utility model is reasonable, and the radiating fins are arranged, thus improving the radiating area of the bulb; the heat dissipation through hole at the bottom of the heat radiator, the heat dissipation through hole at the top of the heat radiator and the heat dissipation through hole at the top of the lampshade form cold and hot air convection of a hollow space of the heat radiator; the heat dissipation efficiency of the bulb is improved by the groove-shaped heat dissipation through holes at the bottom of the transparent lampshade and the cold and hot air convection of the hollow space of the lampshade formed by the heat dissipation through holes at the top of the lampshade, the service life of the bulb is prolonged, and the bulb is high in applicability and practicability.
