Description

Face array light splitting piece and adopt the LED lamp of this face array light splitting piece

Technical field

The utility model relates to a kind of array light splitting piece and adopts the LED lamp of this face array light splitting piece.

Background technology

Light emitting diode relies on its excellent performance just progressively to move towards household and commercial lighting, uses very extensive.There are problems such as brightness is little in single light emitting diode in the application of illumination.The LED integrated lamp tube then can overcome the problem of luminance shortage, so the LED integrated lamp tube also more and more is welcomed by the general public.

The LED integrated lamp tube of prior art comprises housing and LED integrated chip circuit block, LED integrated chip circuit block is by printed circuit board (PCB) and a plurality of light emitting diodes provided thereon, LED integrated chip circuit block is located in the housing, described housing is made up of base and transparency cover, LED integrated chip circuit block is located at base and transparency cover cooperates in the cavity that forms, and light emitting diode is towards transparency cover.

The LED integrated lamp tube of this kind structure, because its light is directly by the hyaline test outgoing, can cause light comparatively dazzling, and the formed multi beam light of a plurality of light emitting diodes can cause inhomogeneously, shadow occurs, influences illuminating effect, although prior art has proposed some leaded light components and has solved this problem, but for the spot light of face array, it reached goes out light effect and still can produce shadow, and even light effect is undesirable.

The utility model content

At the shortcoming of prior art, the purpose of this utility model provides the LED lamp that a kind of bright dipping is even, avoid producing the face array light splitting piece of shadow and adopt this face array light splitting piece.

For achieving the above object, the technical solution of the utility model is: a kind of array light splitting piece, it comprises photic zone and is located at first beam splitter layer on the photic zone, is equipped with the array structure that is groove, tongue or its combination of periodically arranging on the first beam splitter layer surface.

Simultaneously, the utility model also provides a kind of array light splitting piece, wherein, comprise that photic zone reaches first beam splitter layer and second beam splitter layer of being located at successively on the photic zone, be equipped with the array structure that is groove, tongue or its combination of periodically arranging on the surface of first beam splitter layer and second beam splitter layer, and the angle of the array structure length direction of two beam splitter layers is 80 °～100 °.

Further, the angle of the array structure length direction of two beam splitter layers is 90 °.

Further, the array structure of first beam splitter layer and second beam splitter layer lays respectively at the lower surface of first beam splitter layer and second beam splitter layer.

The width of this groove or tongue is 0.2-5mm; The height of this groove or tongue is 0.2-5mm; The spacing of adjacent slot is 0.2-5mm.This light splitting piece is strip, square shape, toroidal, elliptical shape or polygon-shaped.

Simultaneously, the utility model also provides a kind of LED lamp that adopts this face array light splitting piece, it comprises lampshade, be located at the circuit board in the lampshade and be located at a plurality of led chips that are the face array arrangement on the circuit board, wherein, on the lampshade exiting surface, be provided with the face array light splitting piece that the spot light of a plurality of led chips is converted to area source, this face array light splitting piece comprises that photic zone reaches first beam splitter layer and second beam splitter layer of being located at successively on the photic zone, be equipped with on the surface of first beam splitter layer and second beam splitter layer and be the groove of periodically arranging, the array structure of tongue or its combination, and the angle of the array structure length direction of two beam splitter layers is 80 °～100 °.

In the utility model, by the double-layer separate photosphere, the spot light of face array can be effectively converted into uniform surface light source, spot light for the face array, compared with the structure of individual layer beam splitter layer, the individual layer beam splitter layer can only be from a direction as laterally sparing light, and for light source longitudinally, its even light effect is not good, and this programme can be effectively with horizontal, light source all carries out effectively even light longitudinally.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.

The utility model discloses a kind of array light splitting piece, it comprises photic zone and is located at first beam splitter layer on the photic zone, is equipped with the array structure that is groove, tongue or its combination of periodically arranging on the first beam splitter layer surface.

Further, as Fig. 1, Fig. 2 and shown in Figure 3, the utility model discloses a kind of array light splitting piece, wherein, comprise that photic zone 1 reaches first beam splitter layer 2 and second beam splitter layer of being located at successively on the photic zone 13, be equipped with the array structure that is groove, tongue or its combination of periodically arranging on the surface of first beam splitter layer 2 and second beam splitter layer 3, and the angle of the array structure length direction of two beam splitter layers is 80 °～100 °.When light this first beam splitter layer 2 of process and second beam splitter layer 3, be the refraction and the diffraction of the array structure 4 of groove, tongue or its combination of periodically arranging, light can evenly emit from second beam splitter layer 3.

Further, in order to reach best even light effect, the angle of array structure 4 length directions of two beam splitter layers is 90 °.
