Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1 to Figure 3, an embodiment of the present utility model, a kind of columnar polyhedron matrix L ED light source, it comprises the substrate 2 being mounted with LED luminescence chip 1, the shell 4 being arranged at the light guide component 3 above described LED luminescence chip 1 and described light guide component 3 can being fixedly mounted on described substrate 2; Described LED luminescence chip 1 is made up of multiple LED chip 11 array; Described light guide component 3 is made up of multiple light-guiding pillar unit 31 array; Described LED chip 11 and described light-guiding pillar unit 31 one_to_one corresponding; Described light-guiding pillar unit 31 is in the inverted cone shape cylinder increased gradually from bottom to top; The end face of described light guide component 3 is by the seamless spliced luminous flat formed of end face of multiple described light-guiding pillar unit 31.Its operation principle is, the light that LED chip 11 sends by penetrating from end face after the multiple total reflection of side after the bottom surface refraction of light-guiding pillar unit 31, thus obtains at the end face of light guide component 3 the uniformly light-emitting plane that has certain rising angle; When LED luminescence chip 1 is made up of the LED chip 11 of multiple color, the light that LED chip 11 sends, by penetrating from end face after the complete colour mixture of side multiple total reflection after the bottom surface refraction of light-guiding pillar unit 31, obtains at the end face of light guide component 3 luminous flat that has the uniform color mixture of certain rising angle; Visible, the utility model is by the setting of above-mentioned light-guiding pillar unit 31, the hot spot that LED luminescence chip 1 can either be made to cast out reaches the uniform effect of colour mixture, can carry out collection optically focused again to the light of the larger angle that LED luminescence chip 1 casts out, and increases the brightness of hot spot.In addition, because LED chip 11 adopts arranged in arrays, there is certain spacing in every two LED chip 11, makes there is good heat-dissipating space between chip, thus obtain higher light efficiency rate, extends the service life of LED chip 11.

In order to improve the utilization rate of light source, the bottom surface of described light guide component 3 is close on described LED luminescence chip 1, and also namely the bottom surface of light-guiding pillar unit 31 is close in LED chip 11.It should be noted that, the base area of light-guiding pillar unit 31 should be greater than the light-emitting area of LED chip 11, to guarantee that the bottom surface of light-guiding pillar unit 31 covers in LED chip 11 completely, the light that LED chip 11 is sent farthest by light-guiding pillar unit 31 pinching, to reach the utilization rate of higher light source.

Owing to considering the end face seamless spliced luminous flat that form of the end face of light guide component 3 by multiple described light-guiding pillar unit 31, therefore, seamless spliced between the end face conveniently realizing light-guiding pillar unit 31, the cross section of described light-guiding pillar unit 31 is preferably square, rectangle, equilateral triangle or regular hexagon.Wherein, the application example when cross section that Figure 4 shows that light-guiding pillar unit is square or rectangular; The application example when cross section that Figure 5 shows that light-guiding pillar unit is equilateral triangle; The application example when cross section that Figure 6 shows that light-guiding pillar unit is regular hexagon.Certainly, the cross section of light-guiding pillar unit also can be other regular polygon.

Preferably, described LED chip 11 is monochromatic LED chip or multi-colored led chip, to meet the need of market.

On the basis of above-described embodiment, the end face of described light guide component 3 is also coated with light-passing board (not indicating in figure), and this light-passing board affects for reducing rising angle further and preventing extraneous dust from entering lamp interior the hot spot effect that LED luminescence chip 1 casts out.

The molding mode of described light guide component 3 comprises as follows:

The first detailed description of the invention: described light guide component 3 and light-passing board are by optical glass or optical-grade plastic integrated injection molding.Thus, light guide component 3 adopts integral structure, during assembling, directly can be located on LED luminescence chip 1 by whole light guide component 3, just can realize the quick position of light guide component 3 without the need to support component, make whole assembling process convenient, accurate.But for the light guide component 3 of integral type, its structure is comparatively complicated, produce and replacement cost higher, whole light guide component 3 must be changed during replacing.

The second detailed description of the invention: described light guide component 3 is split-type structural, light-guiding pillar unit 31 described in each is respectively by optical glass or optical-grade plastic injection mo(u)lding.Further, the inside of described shell 4 is provided with the Turbogrid plates (not indicating in figure) can located for light-guiding pillar unit 31 grafting described in each.Thus, light guide component 3 adopts split-type structural, and the structure of single light-guiding pillar unit 31 is comparatively simple, produce and replacement cost lower, without the need to whole light guide component 3 is changed during replacing.But because light-guiding pillar unit 31 is independently, during assembling, need to use support component (Turbogrid plates) to carry out dress and spell and location, thus easily occur rigging error, efficiency of assembling is lower.

Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
