A kind of LED pendent lamps of double lampshade
The present invention relates to LED lamp field, more particularly to a kind of LED pendent lamps of double lampshade.
Different from common incandescent lamp, LED is to rely on the electronics in heterojunction semiconductor to pass through energy caused by potential barrier
Move more direct luminous.Because luminescence process does not produce heat, energy conversion efficiency overlong service life, is LED close to absolutely
The developing direction of lighting engineering from now on.
In view of the energy saving of LED lamp, increasing lighting apparatus employs LED light source.In fact, LED lamp is not only
Good energy saving property, and it is in light weight, will be light than traditional incandescent lamp and fluorescent lamp, incandescent lamp and fluorescent lamp employ glass material more
Matter, security is also be not as high as LED lamp.Due to weight and safety problem, regulation is cumbersome for traditional incandescent lamp and fluorescent lamp,
Mostly fixed light fixture.For example, traditional pendent lamp, lampshade is mostly fixed structure, it is difficult to changes the scope of illumination, poor practicability.
The content of the invention
The present invention solves the technical problem of a kind of LED pendent lamps of double lampshade are provided, change the structure of lampshade, realize
The change of illumination range.
In order to solve the above technical problems, one aspect of the present invention is：A kind of LED of double lampshade is provided to hang
Lamp, including：Furred ceiling fixed plate, controller, the first lampshade and LED post, the controller are arranged on furred ceiling fixed plate bottom, institute
State LED post and be arranged on controller bottom, first lampshade is arranged on outside LED post, and the LED pendent lamps of the double lampshade are also
Including the second lampshade, second lampshade is set in above the first lampshade, the top of the furred ceiling fixed plate and the second lampshade it
Between be provided with several damping telescopic bars and be connected.
In a preferred embodiment of the present invention, several LED lamps are provided with the LED post.
In a preferred embodiment of the present invention, the top of first lampshade is connected with the bottom of controller.
In a preferred embodiment of the present invention, the damping telescopic bar is hydraulic damping expansion link.
In a preferred embodiment of the present invention, second lampshade is more than the size of the first lampshade, second lampshade
It is coaxially set with the first lampshade.
In a preferred embodiment of the present invention, the inner surface setting of second lampshade and the first lampshade has reflective painting
The beneficial effects of the invention are as follows：A kind of LED pendent lamps for double lampshade that the present invention points out, at the top of room, profit
With damping telescopic bar, the height of the second lampshade can be adjusted manually, so as to change the illumination range of LED post, optically focused is carried out and carries
High brightness or astigmatism expansion range of exposures, easy to adjust, using flexible, good energy saving property are applied widely.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, make required in being described below to embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other
Accompanying drawing, wherein：
Fig. 1 is a kind of structural representation of the preferred embodiment of LED pendent lamps one of double lampshade of the present invention.
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only the part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area
All other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model that the present invention protects
Referring to Fig. 1, the embodiment of the present invention includes：
A kind of LED pendent lamps of double lampshade, including：Furred ceiling fixed plate 1, controller 2, the first lampshade 6 and LED post 3, it is described
Controller 2 is arranged on the bottom of furred ceiling fixed plate 1, and furred ceiling fixed plate 1 is fixed on the top in room.
The LED post 3 is arranged on the bottom of controller 2, and first lampshade 6 is arranged on outside LED post 3, described double
The LED pendent lamps of lampshade also include the second lampshade 7, and second lampshade 7 is set in the top of the first lampshade 6, the furred ceiling fixed plate 1
Several damping telescopic bars 5 are provided between the top of the second lampshade 7 to be connected.The damping telescopic bar 5 is stretched for hydraulic damping
Contracting bar, under manpower effect, damping telescopic bar 5 is stretched, so as to drive moving up and down for the second lampshade 7.
Several LED lamps 4 are provided with the LED post 3, LED lamp 4 is arranged on the surrounding of LED post 3, LED lamp 4
Good energy saving property, luminous efficiency is high, and the radiance sent reflex to outside by the first lampshade 6 and the second lampshade 7.
The top of first lampshade 6 is connected with the bottom of controller 2, the position of the first lampshade 6 be it is changeless,
Second lampshade 7 is more than the size of the first lampshade 6, and second lampshade 7 is coaxially set with the first lampshade 6,
Therefore when the second lampshade 7 moves down, the radiance that the bottom of the second lampshade 7 can be sent to LED lamp 4 reflect, and reduce
The scope of illumination, there is certain optically focused to improve brightness.
The inner surface setting of the lampshade 6 of second lampshade 7 and first has reflecting coating, improves reflective efficiency, increases lamp
The brightness of tool.
In summary, the LED pendent lamps for a kind of double lampshade that the present invention points out, at the top of room, by promoting second
Lampshade 7 changes the scope of illumination, and easy to adjust, use is more flexible, and structure is novel, good decorating effect.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, it is included within the scope of the present invention.
