Abstract

The invention relates to a LED lamp cover and relative assemble structure, which comprises a cover head and a assemble part, which are connected as a whole. Wherein, the cover head has a concave part to match the LED lamp to be transparent, whose inner surface and the bottom have layered wave arc surface that expanding from inner to outer; the assemble part is a projection extending from the edge of cover head to outer in square shape, and it has boss and cut at the edges, while the boss is matched with the cut. The inventive wave arc surface can reflect the light of LED lamp for several times to improve the brightness of LED lamp; and the assemble part can parallel arrange several lamp covers. The invention has simple structure and easy installment.

Description

A kind of LED lampshade

Technical field:

Invention relates to the lampshade technical field, refers in particular to a kind of LED lampshade.

Technical background:

Originally the light-emitting device of commonly using is to adopt incandescent lamp as illuminator, and the deficiency of its existence has: big energy-consuming, heating is severe, service life is short, luminance is lower, and volume is big, and difficult assembling is controlled.Occur to adopt the LED lamp as illuminator subsequently, it has solved the problem that incandescent lamp exists admirably, uses also extensively thereupon, as is applied to flashlight, mini light night, Illuminous decorations, luminescent candle etc.Yet the LED lamp that uses adds lampshade mostly when installing and using at present, only relies on the transparent outer cover cooperation irradiation that the LED lamp itself has, and its emitted light is unsatisfactory, luminance shortage.Thereby seek the problem that lampshade that a kind of cooperated with LED lamp uses has become the concern of manufacturer, improve economy and the practicality of LED with this.

Summary of the invention:

The objective of the invention is to overcome the defective of prior art, a kind of LED lampshade is provided.

For achieving the above object, the present invention includes capouch part and assembled part that transparent material is made, both are connected as a single entity, capouch partly has an inner fovea part to cooperate printing opacity with the LED lamp, the interior perimeter surface of inner fovea part and the bottom surface waveform cambered surface that forms mutual superposition wherein, and the waveform cambered surface of interior perimeter surface was widened by interior being gradually outward, and the interior perimeter surface of inner fovea part is divided into several parts by several by the interior groove that extends outward; Assembled part is the body flange that is extended outward by capouch part periphery, and it is square, and forms projection and breach successively on the edge, and shape, the size of projection and breach match, and the projection that is in the surrounding on the opposite side is corresponding with breach.

The interior perimeter surface of described capouch part inner fovea part is divided into ten halves by several grooves, and the angle of adjacent two grooves is 30 °; And projection on the assembled part surrounding and breach are trapezoidal, the big end of projection outwardly, and the big end of breach is inwardly, projection on each limit and breach number sum are even number.

Adopt such structure, repeatedly reflection can take place in the light that the LED lamp sends on the waveform cambered surface of lampshade inner fovea part, thereby has improved the brightness of illumination of LED lamp, strengthens the practicality of LED lamp.

Another advantage of the present invention is a plurality of lampshades to be made up mutually side by side by the assembled part on the lampshade, and simple in structure, easy to assembly, can satisfy multiple occasion and use.

Description of drawings:

Accompanying drawing 1 is a front view of the present invention;

Accompanying drawing 2 is the sectional structure chart of lampshade part;

Accompanying drawing 3 is the front view of lampshade part;

Accompanying drawing 4 is the present invention's two individual assembling schematic diagrames;

Accompanying drawing 5 is a plurality of body assembling of the present invention schematic diagram.

The specific embodiment:

See shown in the accompanying drawing 1～5, the present invention includes capouch part 10 and assembled part 20 that transparent material is made, both are connected as a single entity, capouch part 10 has an inner fovea part 11 to cooperate printing opacity with the LED lamp, the interior perimeter surface of inner fovea part 11 and the bottom surface waveform cambered surface 111 that forms mutual superposition wherein, and the waveform cambered surface 111 of interior perimeter surface was widened by interior being gradually outward.Assembled part 20 is the body flanges that extended outward by capouch part 10 peripheries, it is square, and on the edge, form projection 21 and breach 22 successively, shape, the size of projection 21 and breach 22 match, the projection 21 that is in the surrounding on the opposite side is corresponding with breach 22, and projection 21 on each limit and breach 22 number sums are even number, and projection 21 and breach 22 are trapezoidal in the present embodiment, the big end of projection 21 outwardly, and the big end of breach 22 is inwardly.

The interior perimeter surface of capouch part 10 inner fovea parts 11 is divided into ten halves by several grooves 112, the angle of adjacent two grooves 112 is 30 °, perimeter surface extended outwardly in groove 112 was carried over by the interior end, the interlaced formation of stack line netted (shown in Figure 3) of groove 112 and waveform cambered surface 111.

The waveform cambered surface 111 that the interior perimeter surface of inner fovea part 11 and bottom surface are designed to mutual superposition, each cambered surface 111 all constitutes a convex mirror.During use, when the light that the LED lamp sends is mapped on the different cambered surfaces 111, refraction has taken place not only, but also can take place repeatedly to reflect, so that the interlaced ejaculation of several light, bigger at the bottom of the angle, wider, brightness is also more sufficient.

Shown in accompanying drawing 4,5, the present invention can mutually combine two or more individualities by assembled part 20, at this moment embedding in the breach 22 in conjunction with the limit of another individualities just of one of them individuality in conjunction with the projection on the limit 21, so that have at least a projection 21 to be embedded on another individuality on each individuality.It is to be convenient to better location assembling and jam is connected that projection 21 and breach 22 are trapezoidal, thereby realizes the combination side by side mutually of a plurality of lampshades, easy to assembly fast.

Certainly, the embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
