Abstract

The invention discloses an LED lamp which comprises an LED chip, a radiating base, a lampshade fixed to the radiating base and a radiating substrate connected between the radiating base and the lampshade, wherein the radiating base is a hollow cylindrical radiating body with a plurality of radial radiating fins formed on the periphery; the radiating fins are arranged in the axial direction of the radiating base; a radiating through hole is formed in the radiating base; the LED chip is fixed to the radiating substrate; a through hole is formed in the radiating substrate; and a drive power supply is arranged on the radiating substrate and electrically connected with the LED chip. According to the LED lamp disclosed by the invention, the radiating substrate is designed for the LED lamp to carry out radiating, and in addition, the radiating through hole is also formed in the radiating base, and the through hole is formed in the radiating substrate, so that air convection radiating between the interior of the lampshade and the external environment is ensured, the radiating performance is greatly promoted, and the service life of a product is prolonged; and as the lampshade and the radiating substrate are detachably arranged, lampshades in multiple styles can be designed for change.

Description

technical field [0001] The present invention relates to the technical field of lighting equipment, and more specifically relates to LED lamps. Background technique [0002] Due to the advantages of long life, high efficiency, and no radiation, LED lights are deeply loved by users. Existing LED lamps generally include a radiator, a spherical lampshade, and an LED chip. One end of the radiator is a lamp cap, and the other end of the radiator is fixed to the LED chip and the lampshade. However, the heat dissipation performance of the LED lamp is extremely critical. Too high temperature will cause the LED to work unstable and even shorten the life. The LED chip of the LED lamp in the prior art can only dissipate heat through the heat dissipation base above it. Therefore, it is necessary to design LED lamps with better heat dissipation effect, simple structure and diversified styles to meet the needs of the LED lamp market. Contents of the invention [0003] In order to solve...
