Description

Each is to the uniformity solid-state illumination

Technical field

The utility model is relevant a kind of solid luminescent assembly, particularly relevant a kind of package structure for LED.

Background technology

After Edison had invented bulb, illumination produced tremendous influence and variation for the mankind's life.Also therefore, human demand for illumination impels illumination that lasting improvement and research and development are arranged after Edison.At present, light emitting diode is likely the leading role of follow-on green energy conservation illumination, because light emitting diode has many advantages, such as solid-state light emitting source, preferable tolerance is arranged, can be crashproof.Compared to traditional lamp source,, on transporting and using, must crashproofly avoid broken owing to all use glass as Transparent lamp shade.In addition, the energy resource consumption of light emitting diode also is minimum in the light source of at present all solid-state illumination, also is the most business-like.

Because the light emitting diode in the present commercial use, the design of its encapsulating structure lets light emitting diode that very high directive property is arranged.In many application facet, this is an advantage.But in general traditional illumination, this has many problems.Owing to begin from the bulb of candle and Edison invention, all till now lightings all are respectively to uniform transmitting illuminant, though needed illumination have only one of them or some towards.But people have been accustomed to using such light source, and are directed against the light fixture of such light source design illumination.When light emitting diode need be applied in traditional lighting, will consider how to solve the problem of high directivity.

Seeing also Fig. 1, is to show to use the lampshade of traditional bulb lamp to cover the light-emitting diode structure sketch map at present.A plurality of light emitting diodes 30 are positioned on the printed circuit board (PCB) 20, and transmitting illuminant, and the external form of lampshade 10 mainly is the appearance structure of the traditional bulb lamp of imitation.Lampshade 10 can be a material transparent or the cloudy surface printing opacity, can be PMMA, acryl, PC, PE, PVC etc. basically.Light emitting diode 30 can be the monochromatic light light emitting diode of different color lights such as gallium nitride, GaAs, AlGaInP or the white light emitting diode behind the mixed light.

In Fig. 1, be example with one of them light emitting diode emitted light beams 32, launch through the light beam 32 ' that only can produce translation after the lampshade 10, the direction between these two light beams 32 and 32 ' does not change basically.This expression adds the lighting angle that upper lamp shade 10 can't change light emitting diode 30, so the illumination of whole light fixture still has high directive property.

Because the light source of this high directivity is the encapsulating structure that comes from light emitting diode, be a kind of mode so revise the encapsulating structure of light emitting diode.But; Because the volume of light emitting diode is minimum, the change encapsulating structure has the problem of other application end, and for example several light emitting diodes are arranged in together; In the middle of shine the other side mutually light beam not only can be absorbed by light emitting diode, also can reduce the life-span of light emitting diode and the brightness of use.Therefore, on encapsulating structure, revise, be not necessarily a desirable mode.

The specific embodiment

For demand that meets the industry interests and the purpose that reaches the utility model; The utility model provide each to inhomogeneity solid-state illumination; It comprises provide one have a light beam of a first direction the solid luminescent source; And one Transparent lamp shade cover this solid luminescent source, this Transparent lamp shade tool inner surface has a plurality of micro-structurals, and this light beam is scattered out with non-this first direction.

Above-mentioned solid luminescent source is a light emitting diode.

The shape of above-mentioned Transparent lamp shade is near the external form of bulb lamp.

Above-mentioned a plurality of micro-structurals are distribution symmetrically on this Transparent lamp shade.

Above-mentioned a plurality of micro-structurals are to be bulge-structure, and its relief structure can be pyramid or taper shape.

Above-mentioned a plurality of micro-structurals are to be sunk structure, and wherein sunk structure can be pyramid or taper shape.

The utility model is a kind of solid-state illumination in this direction of inquiring into.In order to understand the utility model up hill and dale, detailed step and composition thereof will be proposed in following description.Apparently, the execution of the utility model is not defined in the specific details that the solid-state illumination those skilled in the art are had the knack of.On the other hand, well-known composition or step are not described in the details, with the restriction of avoiding causing the utility model unnecessary.The preferred embodiment meeting of the utility model is described in detail as follows, yet except these were described in detail, the utility model can also be implemented among other the embodiment widely, and the scope of the utility model constrained not, and it is as the criterion with claim afterwards.

A kind of settling mode of the utility model sees also Fig. 2, is on application end, just adds some protruding micro-structurals 12 in the inside of lampshade 10.When the light beam 34 of light emitting diode is transmitted into one of them protruding micro-structural 12, will produce the folded light beam 34 ' of wide-angle, in the equivalence zone that can the light beam of light emitting diode partly be refracted to other.In Fig. 2, lampshade 10 can be ignored and not remember for the translation effect that light beam produces, because the emphasis of the utility model is to be whether light beam has an opportunity to produce the refract light of wide-angle through lampshade 10.Protruding micro-structural 12 can be pyramid or taper shape.

Certainly, can in lampshade 10, design protruding micro-structural 12, also can design the micro-structural 12 ' that depression is gone, as shown in Figure 3.Convexity and the micro-structural that caves in, the light beam that only need let light emitting diode produce can produce the equivalent refract light of going up wide-angle and get final product.Certainly, also can protruding micro-structural with depression all be distributed in the inboard of lampshade 10.The micro-structural 12 of depression can be pyramid or taper shape.

No matter be the micro-structural of convexity or the micro-structural of depression, the surface distributed at lampshade 10 sees also Fig. 4, for each distributes to even (Omni-directional), can provide each to uniform deflecting light beams.The part emission light beam of light emitting diode can directly pass lampshade 10 and shine out; And emission light beam partly can produce the deflecting light beams of wide-angle through the micro-structural 12 of lampshade 10; And then simulate the light source that is similar to the traditional lighting light fixture, reduced of the influence of the high directivity of light emitting diode for the illumination application end.

See also Fig. 5, except adding some protruding micro-structurals 12 or the depression micro-structural 12 ' of going, also can be designed to the micro-structural 13 of ring-type, can produce the refract light of wide-angle equally.
