Abstract
A light-emitting diode packaging structure capable of shortening the light outlet angle comprises a reflection cup body, a light-emitting diode and a packaging body. The reflection cup body is provided with at least one first electric connection portion and a second electric connection portion, and a coarsening microstructure is formed on the reflection lateral wall. The light-emitting diode is arranged in the reflection cup body and forms electric connection with the electric connection portion and the second electric connection portion. The packaging body is arranged on the reflection cup body and wraps the light-emitting diode, and the surface roughness of the reflection lateral wall is over 4.5mum. The reflection cup body is in the square groove shape, and the formation face of the coarsening microstructure is set on the four reflection lateral walls according to the wanted produced light shape. The light-emitting diode packaging structure has the advantages of shortening the light outlet angle, shortening the light outlet angle in the specific direction and improving color temperature evenness of a lighting module.
Description
Technical field
The utility model relates to a kind of reflective side walls in the reflection cup and is formed with the alligatoring micro-structural; And then the direct of travel that changes light dwindles rising angle; And can promote the design of the illuminating module colour temperature uniformity, particularly a kind of package structure for LED that dwindles rising angle.
Background technology
Light-emitting diode technological increasingly mature, it is applied in the life and is seen everywhere, and generally is used on the indicating device and display unit of information, communication and consumption electronic products; Yet light-emitting diode is supported by necessity that encapsulating structure gives electricity, light and heat, so optical design is for the important ring of encapsulating structure, how more effectively to go out photoconduction, and rising angle and direction all are the emphasis in the design.
Moreover; With the fluorescent material of first kind of different color and luster of photochromic utilization inspire second kind photochromic; And then be mixed into the third photochromic mixed light application very generally, and for example adopt blue light-emitting diode to add the yttrium-aluminium-garnet yellow fluorescent powder, utilize blue-light excited yellow fluorescent powder to produce white light; But because the thickness of phosphor powder layer and the uniformity are difficult to control, still can cause colour temperature to disperse uneven phenomenon behind the mixed light at present.
The utility model content
The utility model technical problem underlying to be solved is; Overcome the above-mentioned defective that prior art exists; And a kind of package structure for LED that dwindles rising angle is provided; It has the effect that rising angle is dwindled, and also has the effect that the specific direction rising angle is dwindled, and has the effect that promotes the illuminating module colour temperature uniformity.
The utility model solves the technical scheme that its technical problem adopted:
A kind of package structure for LED that dwindles rising angle includes: a reflection cup is provided with first electrical junction and second electrical junction at least, and is formed with the alligatoring micro-structural in reflective side walls; One light-emitting diode is arranged at this reflection cup inside, and constitutes electric connection with this first electrical junction and second electrical junction; And a packaging body, be arranged at this reflection cup and this light-emitting diode is coated.
In addition, the surface roughness of this reflective side walls reaches more than the 4.5 μ m.
The aforesaid package structure for LED that dwindles rising angle, wherein reflecting cup is square groove shape, and the light shape that produces according to the institute desire and set the formation face of alligatoring micro-structural in its four reflective side walls.
The beneficial effect of the utility model is that it has the effect that rising angle is dwindled, and has the effect that the specific direction rising angle is dwindled, and also has the effect that promotes the illuminating module colour temperature uniformity.

Embodiment
At first; See also Fig. 1～shown in Figure 4; The utility model includes: a reflection cup 10a, 10b are provided with first electrical junction 11 and second electrical junction 12 at least, and are formed with the alligatoring micro-structural in reflective side walls 13; Shown in Fig. 3, Fig. 3 A, it is above for preferable that the surface roughness of this reflective side walls 13 reaches 4.5 μ m; One light-emitting diode 20 is arranged at this reflection cup 10a, 10b inside, and constitutes electric connection with this first electrical junction 11 and second electrical junction 12; And a packaging body 30, be arranged at this reflection cup 10a, 10b and this light-emitting diode 20 is coated.
Yet; If this reflection cup 10b is Fig. 2～square groove shape shown in Figure 4; The light shape that then produces according to institute's desire is set the formation face of alligatoring micro-structural in its four reflective side walls 13, and then satisfies different light shape demands, has the effect that the specific direction rising angle is dwindled.。
Based on said structure, the utility model is formed with the alligatoring micro-structural in the reflective side walls 13 of reflection cup 10a, 10b, and then destroys the scattering of light situation, and the direct of travel that changes light dwindles rising angle; Be with, have the effect that rising angle is dwindled.The person if be applied to use the illuminating module of fluorescent material, then has the effect that promotes the illuminating module colour temperature uniformity in addition.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
In sum; The utility model is on structural design, use practicality and cost benefit; It is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, has novelty, creativeness, practicality; The regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
