Background technology

LED is owing to little, the advantages such as power consumption is low, long service life of its volume, to become the development trend of lighting source.For existing LED illuminating lamp, its illuminator generally all is to be distributed on the plane matrix, and illumination is confined on the direction, and illumination zone is little, can't realize effective lighting for height with the approaching scope of light source.In addition, existing LED illuminating lamp, its illuminator all are circular, no matter adopt which kind of mode to arrange, how intensively arrange, and the slit is all arranged between the adjacent illuminator, and the existence in this slit has caused the discontinuity of led light source, has reduced the luminous efficiency of light source.

The utility model content

The utility model technical problem to be solved provides a kind of luminous efficiency height, the wide seamless light source of sphere great power LED of illumination range.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: the seamless light source of a kind of sphere great power LED; Comprise heat sink and be distributed in the illuminator on the heat sink; Described heat sink is the arc of sphere, hemispherical or compound bending; It is made up of a slice fin, or is made up of two above fin butt joints; Illuminator is a hexahedron structure, and in its six faces, two bottom surfaces are rectangle up and down, and at least two adjacent sides are the inclined plane; The one side relative with this side fits on the illuminator adjacent with another of the side that illuminator tilts.

Described illuminator is through resin and heat sink bonding.

Described illuminator is made up of the resin-encapsulated body and the luminescence chip that are hexahedron structure, and luminescence chip is arranged in the resin-encapsulated body, and links to each other with the wiring pin at resin-encapsulated body two ends.

Two adjacent sides are the inclined plane on the said illuminator, and two other lateral vertical is in the last bottom surface of illuminator.

Four sides are the inclined plane on the said illuminator.

The inclination angle of the inclined side of said illuminator is 10 °-30 °.

Described heat sink is provided with louvre.

The beneficial effect of the utility model is: led light source adopts the sphere design, has effectively improved illumination range.This light source forms with the high power spot light encapsulation of single glass 1 chip with special shape or single glass of polycrystalline sheet.On the illumination meaning, with the massive plate light source relatively, this sphere light source good use optical principle, can reduce light and disturb, directly promote light efficiency.The sphere light source makes light can invest a plurality of directions, effectively improves illumination range, under the light conditioned reflex, also can bring into play its normal light efficiency, and can obtain stronger illuminance in place far away, in illumination range, produces uniform lighting effect.The structure of illuminator and set-up mode have been realized the slitless connection of adjacent illuminator, and the seamless light source that is constituted has significantly improved luminous efficiency, and the light source of equal-wattage, its light efficiency are compared with LED lamp in the past and improved more than 20%.And this light source also can be brought into play its normal light efficiency under the light conditioned reflex.

The specific embodiment

As shown in the figure; The seamless light source of a kind of sphere great power LED comprises heat sink 1 and is distributed in the illuminator 2 on the heat sink 1 that described heat sink 1 is the arc of sphere, hemispherical or compound bending; It is made up of a slice fin, or is made up of two above fin butt joints.As shown in Figure 3, heat sink 1 is the spherical structure that two hemisphere constitute, and a hemisphere also can only be set process semiglobe, and the quantity of splicing fin is decided according to the processing needs.Shown in Figure 2ly be the arcuate structure of compound bending, the heat sink 1 of this embodiment can only be made up of a slice fin.Described heat sink 1 is provided with louvre 6.Illuminator 2 is a hexahedron structure, and in its six faces, two bottom surfaces are rectangle up and down, and at least two adjacent sides are the inclined plane.The inclination angle of the inclined side of illuminator 2 is 10 °-30 °.The inclined plane that is provided with is in order illuminator 2 to be spliced into the arcuate structure of needed sphere or compound bending.When mounted, the one side relative with this side fits on the illuminator adjacent with another of the side that tilts of illuminator.A kind of set-up mode does, two adjacent sides are the inclined plane on the illuminator 2, and two other lateral vertical is in the last bottom surface of illuminator.During installation, the vertical side on the illuminator adjacent with another of the inclined side on illuminator is fitted.Another kind of set-up mode is as shown in Figure 4, and four sides are the inclined plane on the illuminator 2.Described illuminator 2 is through resin and heat sink 1 bonding, the space of corner in the time of when boning, can adopting resin to fill up splicing.

As shown in Figure 4, illuminator 2 is made up of resin-encapsulated body that is hexahedron structure 3 and luminescence chip 4, and luminescence chip 4 is arranged in the resin-encapsulated body 3, and links to each other with the wiring pin 5 at resin-encapsulated body 3 two ends.

In the utility model, the light that each illuminator produces gets into the resin-encapsulated body of adjacent illuminator through superrefraction at the interface place of illuminator, and each illuminator is auxiliary each other, has significantly improved the luminous efficiency of light source.The inclined plane of illuminator has 10 °-30 ° inclination angle, and the seamless light source of forming with the inclined plane butt joint of this angle has more satisfactory light transmission angle and luminous cambered surface, thereby the luminous efficiency of light source and illumination range all are improved.The optimum angle of inclination on illuminator inclined plane is 15 °-20 °.The light source of present technique scheme, throw light is concentrated, and irradiation distance is far away, still can obtain stronger illuminance on ground far away.Through test, adopt the light source of present technique scheme, to compare with led light source with constant power, luminous efficiency has improved more than 20%, and under the light conditioned reflex, also can bring into play its normal light efficiency.The spherical light source of the utility model can be applicable to various illumination street light fittings flexibly, is particularly useful for the large-scale light source of high-power illumination, the luminescence chip power 1-3W of each illuminator, and luminous efficiency is high, and energy-saving effect is more obvious.
