Abstract

The utility model discloses a light emitting diode (LED) lamp capable of adjusting direction of light rays, which comprises a lamp holder and a shell which is provided with circuits, and further comprises a plurality of LED components which are connected with the shell through universal pipes, wherein each LED component comprises a lamp shell, a transparent plate, an LED luminescent plate and a ring-shaped gland, one end of the lamp shell is connected with the shell through the universal pipes, the transparent plate is covered on an opening which is arranged on the other end of the lamp shell, the LED luminescent plate is arranged on one side of the lamp shell close to the transparent plate, and the ring-shaped gland is distributed around the transparent plate, and is used to limit the transparent plate on the edge of the lamp shell. The LED components can rotate in any direction through the universal pipes, can illuminate toward different directions simultaneously, can be positioned and connected with each other through clamp hooks and clamp slots which are matched with each other, and can rotate toward a same direction at the same time. Each LED component has uniform light ray effect through a reflection cup.

Description

The adjustable LED light fixture of a kind of radiation direction

Technical field

The utility model relates to illumination application, more particularly, relates to the adjustable LED light fixture of a kind of radiation direction.

Background technology

Traditional lighting field use the light source such as incandescent lamp, fluorescent lamp as illuminator, not only power consumption is large, heat is high, light efficiency is low, easy fragmentation and have ultraviolet ray pollute, environment is worked the mischief, under the environment of global resources anxiety, be eliminated gradually

LED is a kind of semiconductor that can be visible ray by electric energy conversion, its basic principle of luminosity is in carrier recombination process, to emit excess energy in semiconductor, cause photo emissions and electric energy is converted into luminous energy, more existing incandescent lamp, gas-discharge lamp are compared, there is principle of luminosity advanced person, without plurality of advantages such as mercury pollution, along with improving constantly of technology, technological level, the illumination scheme using LED as light source increasing field progressively replaces conventional light source scheme.

As the application number Chinese disclosure of the invention that is 200910037231.9 the radiator structure of a kind of LED, comprise the radiator of being made by hot good conductor, and at least one is arranged on the LED on described radiator.It is on radiator, to be provided with one or one or more groove, two pins of LED are electrically connected in the described groove of rear insertion by conducting connecting part, and be fixedly clamped or undertaken fasteningly by metal or nonmetal sieve silk by groove, LED pin and radiator keep insulation isolation.But the irradiation position of the LED of this patent is fixed, can not free adjustment.

Granted publication number is the LED lamp that the patent documentation of CN202392636U discloses a kind of adjustable direction of illumination, comprise support, lamp socket, lamp body and lampshade, described support upper end fixed lamp-socket, lamp socket upside fixed lamp body, described lamp body one side is provided with lampshade, and described lampshade lower end is fixed on support in the mode being flexibly connected by fixed bar.Its advantage is that the position that can pass through adjustment lampshade changes direction of illumination, easy to use.Although but the LED lamp of this patent documentation can change direction of illumination, changes direction form single, applicability is not strong.

Utility model content

The utility model, for the problems referred to above, has proposed the adjustable LED light fixture of a kind of radiation direction.Solve LED radiation direction single, can not freely regulated problem.

The technical scheme that the utility model is taked is as follows:

The adjustable LED light fixture of a kind of radiation direction, comprises lamp socket and settles the housing of circuit, and also comprise some LED assemblies that are connected with described housing by Universal pipe, each LED assembly comprises:

Lamp housing, one end of this lamp housing is connected with described housing by Universal pipe;

Light-passing board, covers on the opening of the described lamp housing other end;

LED luminous plaque, is positioned at the side of lamp housing near light-passing board;

Annular gland, around described light-passing board edge distribution, for light-passing board being limited to the edge of described lamp housing.

When use, can turn to any direction by the each LED assembly of Universal pipe, meet different user demands, as in library, regulate each LED assembly, light-passing board is towards different positions, make the good reading light of all having of these positions, facilitate each reader's reading.

As preferably, described lamp housing is square.The lamp housing of square is easy to process, and each lamp housing combine also more attractive in appearance, location also more for convenience.

As preferably, in described lamp housing, be also provided with reflector, the bottom centre position of reflector is provided with through hole, and described LED luminous plaque is positioned at through hole.Can make LED light more even by reflector.

As preferably, described lamp housing sidewall is provided with louvre.

As preferably, that end that described lamp housing is connected with Universal pipe is provided with louvre.

As preferably, the quantity of described LED assembly is 4, and on each lamp housing, is equipped with a snap fit and draw-in groove for fixing with other lamp housings.The cooperation of snap fit and draw-in groove can be located each LED assembly accurately, can, simultaneously to an angle rotation, can rotate separately again, has strengthened the applicability of light fixture.

As preferably, on the lamp housing of each LED assembly, be equipped with a gauge tap, control opening and closing of the interior LED luminous plaque of this lamp housing.

The beneficial effects of the utility model are: some LED assemblies can rotate to any direction by Universal pipe, can irradiate to different orientation simultaneously; By the snap fit and the draw-in groove that cooperatively interact, between LED assembly, can mutually locate and connect, can rotate to a direction simultaneously; By reflector, make each LED assembly all there is uniform light effects.
