Problems solved by technology
However, this heat dissipation method is passive. Usually, a hole connecting the inside and outside is provided on the lamp holder, and then it is carried out by the air's own cooling and heating characteristics. The heat dissipation and convection speed are slow, so the heat dissipation effect is also very limited, especially for more The larger the lamp, the worse the heat dissipation effect, which greatly affects the use effect and service life of the lamp

Embodiment Construction
[0026] Best practice:
[0027] Refer to attached figure 1 , LED lighting fan heat dissipation device, including lamp cap 1, partition 2, fan 3, fixed plate 4 and heat dissipation tube 5 for installing lamp beads; wherein partition 2 and fixed plate 4 are made of plastic, and heat dissipation tube 5 It is made of aluminum metal.
[0028] The upper cover 1 of the lamp cap is a conical structure, specifically a pyramidal structure with an isosceles trapezoidal cross-section. There are a plurality of elongated through holes 11 evenly distributed on the conical slope, and the length of each elongated through hole 11 is The direction is consistent with the direction of the generatrix of the cone, and they are distributed along the direction of the generatrix of the cone. Lamp cap loam cake 1 connects lamp cap 7.
[0029] The cross-section of the partition 2 is H-shaped, and consists of an upper edge 21, a lower edge 22, and an annular plate 23 in the middle. The annular plate 23 ...

The invention relates to a cooling device for an LED lamp, in particular to an LED lamp with a fan cooling device. The LED lamp with the fan cooling device is structurally characterized in that the lamp comprises a lamp base upper cover, a fan, a fixing plate, a cooling cylinder, a lamp bead panel and a lampshade, wherein the fan is used for providing power for air convection, and a U-shaped cooing air channel is formed by the cooling cylinder and the lamp bead panel; airflow enters an inner cavity of the cooling cylinder from an annular hole in the inner side of the fan, then is blocked by the disc-shaped lamp bead panel so as to turn by 180 degrees to be guided into a strip-shaped air return space and finally is guided to the outside through an annular hole in the outer side. The LED lamp with the fan cooling device has the advantages that the U-shaped cooling air channel closely surrounds the cooling cylinder and makes full contact with a heating source, heated air is effectively taken away under the action of strong convection airflow provided by the fan, and the cooling effect is good. According to the LED lamp with the fan cooling device, the minitype fan is installed in the LED lamp, in this way, large air convection is provided for the LED lamps, and a good cooling effect is achieved through the cooling cylinder; a basis is provided for further improvement of the light-emitting effect of the LED lamp.
Description
technical field [0001] The invention relates to a heat dissipation device for an LED lamp, in particular to an LED lamp with a fan heat dissipation device. Background technique [0002] In the prior art, an LED lamp includes a lamp holder, a lamp bead column, a lamp driving circuit, a lamp holder and a light bulb. The lamp holder is connected to a power supply and connected to the lamp holder. Connect to the power supply, and the other end is connected to the lamp bead board on the lamp bead post; the lamp bead post is located above the lamp holder and is fixedly connected with the lamp holder. Airtight connection. [0003] The lamp holder is used as the heat sink of the lamp, and it generally has cooling channels to facilitate the convection exchange of air in the lamp. However, this heat dissipation method is passive. Usually, a hole connecting the inside and outside is provided on the lamp holder, and then it is carried out by the air's own cooling and heating character...
