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 irradiation range is limited. not effectively

Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the light-emitting diode lamp of the present invention includes a lamp frame 10, two lamp bodies 30 installed on opposite sides of the lamp frame 10 and parallel to each other, and a reflector installed above the lamp body 30 for reflecting the light emitted by the lamp body 30. plate 50.

[0014] The reflector 50 is generally airfoil-shaped, and includes a longitudinal mounting portion 51 and two reflective portions 53 extending obliquely upward from opposite sides of the mounting portion 51 . The two reflectors 53 are placed above the two lamp bodies 30 for reflecting the light emitted by the lamp bodies 30 .

[0015] The lamp stand 10 includes a cuboid fixed rod 11 , a lamp holder 12 fixedly connected to the lower middle of the fixed rod 11 , and a support rod 13 arranged in the upper middle of the fixed rod 11 . The fixing rod 11 , the lamp holder 12 and the supporting rod 13 together form a "cross"-shaped structure. A nu...

Abstract

The invention relates to a light-emitting diode lamp which comprises a lamp bracket and a lamp body arranged at one side of the lamp bracket, wherein the lamp body comprises a plurality of light-emitting diode modules and a lamp shade covering the light-emitting diode modules in, wherein the lamp shade is shaped as a cylinder, the lamp body also comprises a first radiator which is accommodated into the lamp shade and is attached by the light-emitting diode modules, and a second radiator which is arranged outside the lamp shade and supports against two opposite ends of the first radiator. Compared with the prior art, the light-emitting diode lamp is provided with the second radiator positioned outside the lamp shade, which can radiate head in the lamp shade into surrounding air so as to reduce the temperature in the lamp shade and ensure stable work of light-emitting diodes.

Description

technical field [0001] The invention relates to a lighting device, in particular to a light emitting diode lamp. 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 accumulates in the lampshade. The air with these hea...
