Abstract
The utility model provides a patch light emitting diode, comprising a pedestal, a reflection rubber cup, a light emitting diode chip and a colloid. The utility model is characterized that the reflection rubber cup is positioned on the pedestal; the light emitting diode is positioned in the inside of the reflection rubber cup; the colloid is filled in the reflection rubber cup; the light emitting diode chip electrode is connected with the electrode of the pedestal; what's more, the mouth surface of the reflection rubber cup is curved; the colloid is arranged as curved surface colloid lens on the light emitting diode chip. The utility model has the advantages that the mouth surface of the reflection rubber cup of the light emitting diode is curved and the colloid is arranged as curved surface colloid lens on the light emitting diode chip.
Description
[technical field]
The utility model relates to a kind of light-emitting diode, relates in particular to a kind of paster type light emitting type.
[background technology]
At present, in the packaging technology of paster type light emitting type product, establish the package cavity of depression on the support of being everlasting, establish led chip in the package cavity, again toward the interior embedding colloid of package cavity, colloid will irritate flat in the package cavity.Described package cavity can not go out whole photoconductions fully for flat mouthful of plastic cement package cavity, and light emission rate is lower.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of paster type light emitting type, its light extraction efficiency height.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of paster type light emitting type is provided, comprises support, reflection glue cup, light-emitting diode chip for backlight unit and colloid; Described reflection glue cup is located on the support, and light-emitting diode chip for backlight unit is installed in the reflection glue cup, and the colloid can is in reflection glue cup; Described light-emitting diode chip for backlight unit electrode is connected with electrode on the support; Wherein, the rim of a cup surface of described reflection glue cup is curved surface under the surface tension effects of colloid, and described colloid is curved surface colloid lens above light-emitting diode chip for backlight unit.
The rim of a cup of described paster type light emitting type is provided with toroidal lens.
Compared with prior art, the rim of a cup surface of the utility model paster type light emitting type reflection glue cup is curved surface, and colloid of can forms the colloid lens of curved surface in it above light-emitting diode chip for backlight unit.
In addition, the toroidal lens above rim of a cup can increase substantially the luminous efficiency of paster type light emitting type.
[description of drawings]
Fig. 1 is the schematic perspective view of the utility model one preferred embodiment.
[embodiment]
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, it is a preferred embodiment of the utility model paster type light emitting type, it comprises support 1, reflection glue cup 2, light-emitting diode chip for backlight unit 3 and colloid (not indicating among the figure), described reflection glue cup 2 is located on the support 1, light-emitting diode chip for backlight unit 3 is installed in the reflection glue cup 2, and the colloid can is in reflection glue cup 2.
Described support 1 is rectangular structure, and its two ends are provided with two electrodes 10.The groove that described reflection glue cup 2 forms for the mediad lower recess of support 1, bottom center in reflection glue cup 2 is provided with a light source region 20, described light-emitting diode chip for backlight unit 3 is installed on the light source region 20, and by ultra-sonic welded, the electrode 30 of light-emitting diode chip for backlight unit 3 is connected on the electrode 10 on the support 1.
The positive side of described reflection glue cup 2 is parallel with trailing flank, left surface and right flank are the inclined-plane from the slightly past reflection glue of the upper surface 12 cup 2 centers inclination of support 1, the bottom surface is the plane, rim of a cup 22 surfaces of described reflection glue cup 2 are for being the curved surface of profile of tooth, after in reflection glue cup 2, filling colloid, thinner because of rim of a cup 22 surfaces, under the surface tension effects of colloid, form toothed surface.So colloid forms the colloid lens of several tooth surfaces above light-emitting diode chip for backlight unit 3.The tooth surface lens 4 that are sticked on rim of a cup 22, described toroidal lens 4 is identical with the profile of tooth on rim of a cup 22 surfaces.
The highest principle of light emission rate of the light that sends according to focus on the optical axis in the convex lens, under the optical effect of toroidal lens 4, add several tooth surface colloid lens, the light that can fully light-emitting diode chip for backlight unit 3 on toroidal lens 4 optical axises be sent emits, and can improve the luminous efficiency of paster type light emitting type.
The surface of reflection glue cup 2 rims of a cup 22 of above-mentioned paster type light emitting type is tooth surface, colloid of can forms the colloid lens of several tooth surfaces in it above light-emitting diode chip for backlight unit 3, and above rim of a cup 22, paste tooth surface lens 4, can increase substantially the luminous efficiency of paster type light emitting type.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
