Abstract

An LED light fitting having heat dissipation structure comprises a plurality of LED modules, a first radiator which is closely provided with the LED modules, a lampshade that covers the LED modules and the first radiator, a base installed at one end of the lampshade, and a second radiator arranged at the other end of the lampshade; wherein, one part of the second radiator is arranged inside the lampshade and leans against the first radiator, and the other part is arranged outside the lampshade. Compared with the prior art, the second radiator arranged outside the lampshade is connected with the first radiator which is closely provided with the LED modules inside the lampshade by the LED light fitting, so that the heat generated by an LED is rapidly transmitted from the first radiator to the second radiator and then dissipated out, thus realizing better heat dissipation effect of the LED light fitting, and ensuring the LED modules to work effectively and stably.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp with a heat dissipation structure. Background technique [0002] As an efficient light source, light-emitting diodes have many characteristics such as environmental protection, high brightness, power saving, and long life, and have been widely used in various fields. However, light-emitting diodes generate heat when they work, especially some high-power light-emitting diodes used for lighting. If the heat is not dissipated in time, it is easy to cause overheating, which will lead to a decrease in its luminous efficiency. [0003] A traditional light emitting diode lamp includes a cylinder with heat dissipation effect, several LED modules are installed on the outer wall of the cylinder, and a lampshade covers the light emitting diode modules inside. When the light-emitting diodes are lit, the temperature inside the lampshade gradually increases; after a ...
