Detailed Description

The invention is further illustrated by the following figures and examples.

As shown in fig. 1 and 2, the present invention provides an LED lamp 10 including: the LED lamp comprises a substrate 110 with an LED lamp bead 111 integrated on the surface, a shell 120 connected with the substrate 110, a control board 130 electrically connected with the LED lamp bead 111, and a lampshade 140 connected with the substrate 110. The substrate 110 has a through hole 112 in the middle, and a plurality of heat sinks 121 are connected to the outer surface of the housing 120 to increase the heat dissipation area.

The lamp housing 140 includes a connection plate 142, a plurality of reflective cups 141 connected to the connection plate 142, and a heat sink 150 connected to the connection plate 142. The heat sink 150 is formed by stacking a plurality of layers of mesh sheets. The light reflecting cups 141 correspondingly contain the LED lamp beads 111 one by one, and light emitting holes 1421 corresponding to the light reflecting cups 141 one by one are formed at the joints of the connecting plates 142 and the light reflecting cups 141. A lens is further clamped in the light exit 1421.

A pipe 1422 is connected between the connection plate 142 and the base plate 110, and the pipe 1422 may be a circular pipe, a square pipe, or an oval pipe, preferably a circular pipe. One end of the pipe 1422 passes through the connection plate 142, and the other end of the pipe 1422 passes through the through hole 112 of the base plate 110. The opening at the end of the duct 1422 connected to the connection plate 142 is larger than the opening at the end of the duct 1422 connected to the base plate 110. The connection surface of the pipe 1422 and the connection plate 142 is coated with heat conductive silicone, and the connection surface of the pipe 1422 and the substrate 110 is also coated with heat conductive silicone. The radiator 150 is disposed in the duct 1422, and an edge of each layer of mesh of the radiator 150 is connected to an inner wall of the duct 1422. And the mesh piece is connected the face with pipeline 1422 inner wall and is scribbled heat conduction silica gel. The heat sink 150 has a height equal to the length of the duct 1422.

When the LED lamp 10 is operated, a large amount of heat is accumulated in the LED lamp 10, and the lamp cover 140 and the substrate 110 are designed to be air permeable. The circulation of the hot air in the LED lamp 10 with the outside air is promoted, and particularly, the upward flow of the hot air is facilitated, so that the heat in the LED lamp 10 is dissipated more quickly. The duct 1422 in the middle of the connection plate 142 of the lamp housing 140 may increase a heat dissipation area and better transfer heat, and the heat sink 150 may further increase the heat dissipation area to improve the heat dissipation effect of the lamp housing 140 and the substrate 110, thereby improving the heat dissipation efficiency.
