Description

A kind of LED lampshade

Technical field

This utility model relates to lampshade, specifically a kind of LED lampshade.

Background technology

LED is often to use the illuminations arrived in the modern times.And lampshade is group indispensable in LED Become part.The lamp bead of LED can be played a protective role by lampshade, extends the service life of LED. Current lampshade is often that the installation cavity in full-closed structure, i.e. lampshade has full-closed structure, LED Lamp bead installs installation cavity.LED use process in, LED can be because the temperature of installation cavity be too high Cause damage.Meanwhile, because the lamp holder of LED has different size, therefore need to be equipped with the lamp of sizes Cover, this makes the suitability of lampshade not quite, and easily increases production cost.

Utility model content

The purpose of this utility model is the deficiency overcoming above prior art to exist, it is provided that a kind of structure Simply, heat radiation easy for installation, easy and the LED lampshade of wide adaptability.

In order to achieve the above object, this utility model by the following technical solutions: a kind of LED lampshade, Including drain pan and outer housing, one end of described drain pan is connected with the opening of outer housing, and described drain pan and outer housing Form the installation cavity for mounted LED lamp；The other end of described drain pan is provided with the joint being connected with lamp holder, This joint is stepped；Described drain pan is provided with the first through hole communicated with installation cavity；The closing of described outer housing End is provided with the second through hole communicated with installation cavity.

Preferably, described drain pan is provided with the Os Draconis of cylindrical shape, and these Os Draconis are positioned at installation cavity.

Preferably, one end of described Os Draconis is provided with breach.

Preferably, described first through hole has two groups, the installation cavity between described Os Draconis and outer housing with wherein One group of first through hole communicates, and this organizes the first through hole and is positioned at one end of drain pan；And another is organized the first through hole and is positioned at The other end of drain pan, another is organized the first through hole and communicates with the installation cavity in Os Draconis simultaneously.

Preferably, described in two groups, the first through hole is respectively provided with multiple；And multiple first through holes often organized are all the end of in The circumference of shell is uniformly distributed.

Preferably, described first through hole is strip.

Preferably, one end of described drain pan is connected with the opening of outer housing by screw thread.

Preferably, described second through hole has multiple, and the most rounded；Multiple described second through holes are positioned at The blind end end face of outer housing, and multiple described second through hole is uniformly distributed relative to the circumference of outer housing.

This utility model, relative to prior art, has such advantages as and effect:

1, this LED lampshade mainly has drain pan and outer housing to constitute, and at drain pan and is covered with outward the most respectively First through hole and the second through hole；Then the first through hole and the second through hole produce cross-ventilation and form dissipating of lampshade Heat structure, thus can effectively reduce the temperature in installation cavity, thus ensure that the safety in utilization of LED, Also ensure that the service life of LED.

2, the drain pan in this LED lampshade is provided with joint, and this joint is stepped, then joint can be with The lamp holder of different model (i.e. different size) is connected, thus expands the suitability of lampshade, to reduce Production cost.

Detailed description of the invention

For ease of it will be appreciated by those skilled in the art that below in conjunction with the accompanying drawings and embodiment this utility model made into The detailed description of one step.

As shown in Figures 1 to 5, this LED lampshade, including drain pan 1 and outer housing 2, described drain pan 1 One end be connected with the opening of outer housing 2, and described drain pan 1 and outer housing 2 are formed for mounted LED lamp Installation cavity 3；The other end of described drain pan 1 is provided with the joint 5 being connected with lamp holder 4, and this joint 5 is in rank Scalariform；Described drain pan 1 is provided with the first through hole 6 communicated with installation cavity 3；The blind end of described outer housing 2 sets There is the second through hole 7 communicated with installation cavity 3.First through hole 6 and the second through hole 7 all communicate with installation cavity 3, Then the first through hole 6 also communicates with the second through hole 7, thus the first through hole 6 and the second through hole 7 are easily formed Convection current, therefore can effectively ensure that the heat radiation in installation cavity 3.

Described drain pan 1 is provided with the Os Draconis 8 of cylindrical shape, and these Os Draconis 8 are positioned at installation cavity 3.General, LED Lamp bead in lamp is fixed on substrate, and substrate is a flexible rectangular thin plate, and substrate bending is wound in Dragon Os Draconis, i.e. lamp bead can be installed in installation cavity 3 by substrate；And the design of Os Draconis 8 ensure that lamp bead Stability after installation, improves the reliability of LED work.One end of described Os Draconis 8 is provided with breach 9.The setting of breach 9 can be fixed in the installation of more convenient substrate, i.e. facilitates the installation of lamp bead.

Described first through hole 6 has two groups, installation cavity between described Os Draconis 8 and outer housing 23 with wherein One group of first through hole 6 communicates, and this organizes the first through hole 6 and is positioned at one end of drain pan 1, such as Fig. 1,2 and 4 institutes Showing, this organizes the first through hole 6 and is positioned at the upper end of drain pan 1, and multiple first through holes 6 of this group are along drain pan 1 Central shaft even circumferential distribution.And another is organized the first through hole 6 and is positioned at the other end of drain pan 1, as Fig. 1, Shown in 2 and Fig. 4, the first through hole 6 of this group is positioned at the lower end of drain pan 1, and at joint 5, simultaneously Another is organized the first through hole 6 and communicates with the installation cavity 3 in Os Draconis 8.This two group of first through hole 6 is all with second Through hole 7 communicates, then form two groups of convection current, one of which convection current installation cavity 3 outside Os Draconis 8, the most logical Cross the installation cavity 3 between Os Draconis 8 and outer housing 2, thus can effectively drain the heat of lamp bead；And another group is right Stream installation cavity 3 in Os Draconis 8, thus can effectively drain the heat of other electronic components, thus can be more It is effectively accomplished the effect of heat radiation.

Described in two groups, the first through hole 6 is respectively provided with multiple；And multiple first through holes 6 often organized are all in drain pan 1 Circumference be uniformly distributed.Described first through hole 6 is in strip.This structure can effectively ensure that the stream of air Logical, and ensure that lampshade has certain aesthetic.

One end of described drain pan 1 is connected with the opening of outer housing 2 by screw thread.The connected mode of this screw thread Simple and reliable, convenient installation.

As it is shown on figure 3, described second through hole 7 has multiple, and the most rounded；Multiple described second leads to Hole 7 is positioned at the blind end end face of outer housing 2, and multiple described second through hole 7 is relative to the axis of outer housing 2 Even circumferential is distributed.The smoothness during circulation of this structural gap, and there is certain aesthetic.

Above-mentioned detailed description of the invention is preferred embodiment of the present utility model, can not enter this utility model Row limits, other any change made without departing from the technical solution of the utility model or other equivalence Substitute mode, within being included in protection domain of the present utility model.
