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
[0025] Best embodiment:
[0026] Reference attached figure 1 , LED lamp fan heat dissipation device, including lamp cap upper cover 1, partition 2, fan 3, fixing plate 4 and heat sink 5 with lamp beads; wherein partition 2 and fixing plate 4 are made of plastic material, and heat sink 5 It is made of aluminum metal.
[0027] The lamp cap upper cover 1 is a conical structure, specifically a vertebral structure with an isosceles trapezoid in 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 The direction is consistent with the generatrix direction of the cone, and they are distributed along the generatrix direction of the cone. The lamp cap 1 is connected to the lamp cap 7.
[0028] The partition plate 2 has an H-shaped cross-section and is composed of an upper peripheral edge 21, a lower peripheral edge 22, and a middle annular plate 23. The annular plate 23 has a circular ring...

The invention relates to a heat dissipation device for an LED lamp, in particular to a fan heat dissipation device for an LED lamp. The key points of its structure are that it includes a lamp cap upper cover, a fan, a fixing plate, and a heat dissipation cylinder for installing lamp beads; the heat dissipation cylinder is a hollow annular cylinder Shaped structure, with lamp beads installed on the outer peripheral surface; the middle of the fixed plate is a hollow cylindrical member, and the heat dissipation cylinder is fixedly installed under the fixed plate, and the inner cavity of the heat dissipation cylinder corresponds to the inner cavity of the cylindrical member. Connected, the fan is installed in the cylindrical member of the fixing plate, the air outlet is facing the inner cavity of the cooling tube, the upper cover of the lamp head is connected above the fixing plate, and the cooling tube is covered with a lampshade, and the lampshade is connected under the fixing plate. The advantage is that the micro fan is used in the LED lamp, so as to provide greater air convection for the LED lamp, so that the heat dissipation cylinder can obtain a good heat dissipation effect; further providing a basis for increasing the luminous effect of the LED lamp.
Description
Technical field [0001] The invention relates to a heat dissipation device for an LED lamp, in particular to a heat dissipation device for an LED lamp fan. Background technique [0002] In the prior art, an LED lamp includes a lamp holder, a lamp bead pole, a lamp drive circuit, a lamp holder, and a bulb. The lamp holder is connected to a power source and connected to the lamp holder. The lamp drive circuit is placed in the inner cavity of the lamp holder from below. Connect the power supply, and the other end is connected to the lamp bead board on the lamp bead column; the lamp bead column is located above the lamp holder and is fixedly connected to the lamp holder. The bulb is a transparent or opaque shell that covers the lamp bead holder and is connected to the lamp holder Airtight connection. [0003] As the radiator of the lamp, the lamp holder generally has a heat dissipation channel to facilitate the convective exchange of air in the lamp. However, this kind of heat dissipa...
