Abstract

The invention discloses an LED (light-emitting diode) lamp with a fan. The LED lamp comprises a substrate in which LED lamp beads are encapsulated, a controller, a base, a lampshade and the fan, wherein the controller is electrically connected with the LED lamp beads, the base is connected with the substrate, the lampshade is connected with the base, and the fan is connected with the lampshade; the lampshade comprises a panel and a plurality of reflection cups connected with the panel; the reflection cups hold the LED lamp beads in a one-to-one correspondence manner, and a light outlet hole is formed in the joint of the panel of each reflection cup; air inlets are also formed in the panel; one end, connected with the lampshade, of the base is provided with an adapter ring; a plurality of heat dissipation holes arranged at intervals are formed in the adapter ring; the adapter ring is connected with the panel, and the fan is arranged on the face, connected with the adapter ring, of the panel. When the LED lamp with the fan is turned on, blades of the fan arranged on the lampshade starts to rotate, so that air motion between the lampshade and the substrate is accelerated; under the rotation of the blades of the fan, convection can rapidly occur between the air between the lampshade and the substrate and the air outside the lampshade, so that the heat dissipation efficiency of the LED lamp can be improved.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with a fan. Background technique [0002] LED (Light Emitting Diode), that is, semiconductor electric light source, light-emitting diode, also known as semiconductor lamp, is a kind of electric light source without filament, which directly converts electrical energy into light energy. [0003] LED lights have the characteristics of energy saving and long life, avoiding the trouble of changing bulbs frequently, and are favored by more and more users. However, the heat dissipation problem of LED lights is also a key issue, which seriously affects the light efficiency and life of LED light sources. For traditional LED lamps, the lampshade used for concentrating light is generally closed. Such a lampshade cannot dissipate heat from the substrate, resulting in low heat dissipation efficiency and high temperature of the LED light source, which affects the light efficiency and performance of ...
