Example Embodiment

[0029] Example 1

[0030] Such as figure 1 As shown, an LED lamp includes a lampshade 1, a power box 2 and an LED light-emitting assembly. The LED light-emitting assembly includes an aluminum substrate 3, LED lamp beads (not shown in the figure), and a lens 4. The lampshade 1 is in the shape of a truncated cone with a lower opening, and the lampshade 1 is provided with circular and uniformly distributed elongated heat dissipation holes 5, and the length of the heat dissipation holes 5 is along the bus bar of the lampshade 1, and the heat is uniformly distributed in a circular shape. Holes 5 constitute a heat dissipation hole group;

[0031] It also includes a dust-proof diversion cover sheet 6 whose shape is adapted to the shape of the heat dissipation hole 5; the upper end of the dust-proof diversion cover sheet 6 is connected to the upper end of the heat dissipation hole 5, and the lower end is connected to the heat dissipation hole The lower end of 5 is connected, the circumfer...

[0039] Example 2

[0040] Such as Figure 5 As shown, the whole of the lampshade 1 is in the shape of a cone with a lower opening, the four sides of the lampshade are in an isosceles trapezoid shape, and the upper and lower bottom surfaces are rectangular with rounded corners;

[0041] The elongated heat dissipation holes 5 are uniformly distributed and arranged on the side of the lampshade in a rectangular shape, and the length direction of the heat dissipation holes 5 is along the bus bar of the lampshade 1, and the heat dissipation holes 5 uniformly distributed in a rectangle form a heat dissipation hole group;

[0042] The power supply box 2 is in the shape of a cube with a lower opening. The power supply box 2 is provided with elongated diversion and heat dissipation holes 21 on the circumferential surface, and the diversion and heat dissipation holes 21 uniformly distributed in a rectangular shape constitute a diversion and heat dissipation hole group.

Example Embodiment

[0043] Example 3

[0044] Such as Image 6 As shown, there are four lampshades 1 and two adjacent lampshades 1 are arranged up and down along the axis of the lampshade;

[0045] The lower lampshade 1 is embedded in the upper lampshade 1. The top plate of the lower lampshade 1 is attached to the top plate of the upper lampshade 1 and the diameter of the top plate of the lower lampshade 1 is smaller than the diameter of the top plate of the upper lampshade 1. The upper and lower lampshades 1 There is a heat dissipation gap 8 between the circumferential wall panels.

[0046] The lower end of the upper lampshade 1 is located above the lower end of the lower lampshade 1.

[0047] The heat dissipation method of LED lamps is as follows: LED lamp beads generate a lot of heat when they are working, which are conducted to the lower opening cylindrical lampshade 1 through the aluminum substrate. The lampshade 1 is arranged with multiple large-diameter heat dissipation holes, and the heat dissip...

Abstract

The invention discloses an LED (Light Emitting Diode) lamp. The LED lamp comprises a lamp cover, a power supply box, an LED light emitting assembly and dustproof diversion cover sheets, wherein the lamp cover is in a cone-frustum shape in which a downward opening is formed, and multiple heat dissipation holes are formed in the side surface of the lamp cover and are distributed along the periphery of the lamp cover to form a heat dissipation hole group; the dustproof diversion cover sheets are positioned right ahead the heat dissipation holes and are adapted to the heat dissipation holes in shapes, the upper ends of the dustproof diversion cover sheets are connected with the upper ends of the heat dissipation holes, the lower ends of the dustproof diversion cover sheets are connected with the lower ends of the heat dissipation holes, and two diversion gaps are formed in two sides of space between each dust proof diversion cover and the lamp cover. By adopting the structure, hot air can smoothly flow from the diversion gaps in the lamp cover, heat on the surface of the lamp cover can be rapidly emitted, and the heat dissipation effect is good; the heat dissipation holes are shielded by the dustproof diversion cover sheets, thus the LED lamp has the functions of shading and dust prevention, and the whole appearance is attractive.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to an LED lighting fixture. Background technique [0002] At present, traditional lamps such as industrial and mining lamps, floodlights, tunnel lamps, stadium lamps and the like in the prior art are all equipped with a sunshade. The traditional shading cover has the function of reflecting light to enhance the brightness of light and protecting the lamp from dust. With the development of LED chip technology and packaging technology, LED lamp beads have become a new generation of light source; after using LED illuminants, the light emitted by LED It is directional and weakens the light-gathering effect of the lampshade, but the LED light source requires a good heat dissipation effect to ensure its service life and reduce light decay. The LED light source works in the hood, the heat is accumulated in the hood, and the air does not form convection, which is easy to produce a...
