Problems solved by technology

These heats seriously affect the luminous efficiency and service life of the light-emitting diodes, and, because these light-emitting diodes are located on the same side of the heat sink, the light emitted by them can only radiate outward from this side of the heat sink, and the luminous angle is limited. not effectively

Embodiment Construction

[0012] Such as figure 1 As shown, the LED lamp of the present invention includes several LED modules 20, a heat absorber 30 for attaching the LED modules 20, a radiator 40 located at one end of the heat absorber 30 and closely connected with it, and a lampshade 10. The lampshade 10 is disposed on one side of the radiator 40 and covers the heat absorber 30 and the LED module 20 therein. A lamp holder 50 is disposed in the middle of the other side of the radiator 40 .

[0013] The lampshade 10 is a bowl-shaped structure with an opening, which is usually made of transparent plastic, glass or other materials. The lampshade 10 is placed on the bottom of the radiator 40, and forms a closed chamber with the radiator 40 to accommodate the LED module 20 and the heat absorber 30 and prevent objects such as dust and insects from entering the lampshade 10 and affecting the LED module. Set of 20 lighting effects.

[0014] Please also see figure 2 and image 3 Each LED module 20 incl...

Abstract

An LED light fitting comprises a plurality of LED modules, a lampshade that covers the LED modules, a heat receiver which is positioned in the lampshade and closely provided with the LED modules, and a radiator that is arranged outside the lampshade and is connected with the heat receiver; wherein, the heat receiver comprises a bottom surface contacted with the radiator and a plurality of inclined planes extending from the edge of the bottom surface towards the lampshade to a peak, the inclined planes are distributed in a radial form around the peak, and the LED modules are closely arranged on the inclined planes. Compared with the prior art, as the LED light fitting is provided with the radiator positioned outside the lampshade, the heat in the lampshade can be dissipated into the ambient air to lower the temperature in the lampshade, thereby ensuring the stable work of the LED; furthermore, as the inclined planes of the heat receiver used for carrying the LED modules are distributed in a radial form, the LED modules are arranged along the circumferential direction around the peak of the heat receiver; therefore, the area lightened by the LED is wider than that lightened by the traditional LED.

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 a high-efficiency light source, light-emitting diodes have many characteristics such as environmental protection, 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 LED lamp includes a plate-shaped heat sink, several LED modules installed on one side of the heat sink, and a lampshade that covers the heat sink and the LED modules inside. When the light-emitting diodes are lit, the temperature inside the lampshade gradually increases; after a period of use, a large amount of heat accumulat...
