Description

A kind of LED lamp of scalable irradiating angle

Technical field

The utility model relates to the technical field of LED lamp, particularly a kind of LED lamp of scalable irradiating angle.

Background technology

LED is the abbreviation of Light Emitting Diode, is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.The LED lamp has following advantage than traditional fluorescent lamp: energy-conservation, the life-span is long, applicability good (, can make Any shape) because of the volume of single LEDs is little, and the response time is short, environmental protection, no poisonous metal, discarded object easy recovery etc.; So more and more users is brought into use the illumination of LED lamp.

In existing application, very simply the LED lamp is fixed on the lamp socket often, can not regulate the distance and the irradiating angle of LED lamp source according to actual needs.Though the LED desk lamp of scalable irradiating angle is arranged, put shared space based on desk lamp, and the limitation on the itself height, determined that desk is its maximum stage.

Some LED lamp then is to realize multi-angle illumination through the LED lamp is made special shape, more complicated on the technology not only, and cost is than higher, and height and the intensity that can't regulate light source, and the place applicability is not strong.

In view of this, the inventor improves existing LED lamp, and this case produces thus.

The utility model content

The purpose of the utility model is to provide a kind of LED lamp of scalable irradiating angle, realizes the adjusting of LED lamp three-dimensional perspective through simple annexation, not only can regulate the height and the irradiating angle of light source, can also regulate exposure intensity.

To achieve these goals, the technical scheme taked of the utility model is:

A kind of LED lamp of scalable irradiating angle comprises base, screw mandrel, and slide bar, connecting rod and lamp socket, screw mandrel are installed on the base, and the two ends of slide bar connect screw mandrel and connecting rod respectively, and lamp socket is articulated on the connecting rod, and a slide bar switch also is housed on the slide bar; Slide bar is slidingly installed on the screw mandrel, and does 360 degree around screw mandrel and rotate, and lamp socket is done 360 degree around connecting rod and rotated.

As preferably, slide bar is fixed on the center of connecting rod.

As preferably, the lamp socket on the connecting rod is positioned at the left and right sides of slide bar, is left-right symmetric and distributes.

As preferably, three LED lamps are installed on the lamp socket.

As preferably, the quantity of lamp socket is two or four.

As preferably, connecting rod is an expansion link.

Adopt after the such scheme, the utility model has the following advantages at least:

One, the installation site is unrestricted, can be installed on ceiling, the wall or ground.

Two, the light source height is unrestricted, can reach suitable height through regulating the position of slide bar on screw mandrel.

Three, irradiating angle is unrestricted, can realize the illumination at light source no dead angle on level and vertical plane through rotation slide bar and lamp socket.

Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be described in further detail.

The specific embodiment

To shown in Figure 6, a kind of LED lamp of scalable irradiating angle comprises base 1 like Fig. 1, screw mandrel 2, slide bar 3, connecting rod 4 and lamp socket 5; Base 1 can be fixedly mounted on ceiling, wall or the ground.Screw mandrel 2 is installed on the base 1, can select the length of screw mandrel 2 according to the actual requirements; The two ends of slide bar 3 connect screw mandrel 2 and connecting rod 4 respectively, draw electric wire 7 from base 1 and penetrate the slide bar 3, are connected to lamp socket 5.

As shown in Figure 2, the preferred left-right symmetric of the quantity of lamp socket 5 on connecting rod 4, slide bar 3 is fixed on the center of connecting rod 4, on the lamp socket 5 three common LED lamp 6 can be installed, and also can the LED lamp socket 5 of other number of types be installed through conversion lamp socket 5.First embodiment of the utility model is that with the difference of second embodiment quantity of lamp socket 5 is different, and to shown in Figure 3, in first embodiment, the quantity of lamp socket 5 is 2 like Fig. 1; To shown in Figure 6, in a second embodiment, the quantity of lamp socket 5 is 4 like Fig. 4.

After unclamping slide bar switch 31, slide bar 3 can slide on screw mandrel 2, also can do 360 degree around screw mandrel 2 and rotate; Lamp socket 5 also can be done 360 degree around connecting rod 4 and rotate; And the design of connecting rod 4 employing expansion links, through the length of adjusting connecting rod 4, thus the position of adjustment lamp socket 5.Like this; Such as when base 1 is installed on the indoor ceiling; The user not only can according to the needs of oneself select to let light source near or away from oneself, can also select the direction of illumination of light sources through rotation slide bar 3, further; Can also pass through the rotation of lamp socket 5 on connecting rod 4, select the luminous position of LED lamp.

The lighting angle of the utility model not only can be selected 360 degree illuminations at horizontal level and upright position, can also regulate on the height through screw mandrel 2 to change, and has realized the angle Selection on the three-dimensional, good illumination effect, and the installation site is not limited.

Such scheme is the wherein binomial embodiment of the utility model, and the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
