Abstract

The utility model relates to the field of lighting, in particular to an LED (Light Emitting Diode) lamp with good heat dissipation, which comprises a lampshade, a lamp housing, plugs and an aluminum base plate, wherein the lamp housing is matched with the lampshade to form a lamp tube, and the two ends of the lamp tube are provided with the plugs connected with an external power supply; and the aluminum base plate for loading circuits is arranged between the plugs of the two ends of the lamp tube. A circuit board electrically connected with the outside is arranged on the aluminum base plate, and a plurality of LEDs are arranged on the circuit board, wherein warped pieces with a pectinate heat dissipation structure are also arranged on the lamp housing. The warped pieces increase the heat dissipation area of the lamp housing, and the pectinate heat dissipation structure is beneficial to air convection of the surface of the lamp housing to carry away heat and is beneficial to prolonging the service life of the whole lamp.

Description

A kind of LED lamp that dispels the heat good
[technical field]
The utility model relates to lighting field, specifically refers to a kind of LED lamp that dispels the heat good.
[background technology]
