Abstract
The utility model provides a surface-mounted LED lamp bead with double gold threads. The surface-mounted LED lamp bead with double gold threads comprises a support, a chip, a first gold thread, a second gold thread, and colloid. The support is formed by environment-friendly high-temperature nylon engineering plastics and copper by using injection molding technology. The support is coated with insulating glue and the chip is bonded on the insulating glue. One end of the first gold thread is connected with the chip, while the other end of the first gold thread is connected with the positive pole of the support. One end of the second gold thread is connected with the chip, while the other end of the second gold thread is connected with the negative pole of the support. The colloid is pasted on the support. The chip, the first gold thread, the second gold thread, and the insulating glue are all wrapped in the colloid. The beneficial effect of the surface-mounted LED lamp bead with double gold threads is that the surface-mounted LED lamp bead with double gold threads has advantages of a simple structure, a benefit to production and manufacture, and saving cost.
Description
Technical field
The utility model relates to photoelectric field, relates in particular to the bonded LED lamp pearl with two gold threads.
Background technology
LED lamp pearl is used for luminous, is used in a large number in the middle of the LED light fixture, and present LED lamp pearl complex structure is unfavorable for manufacturing.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of bonded LED lamp pearl with two gold threads.
The utility model provides a kind of bonded LED lamp pearl with two gold threads, comprises support, chip, the first gold thread, the second gold thread, colloid, and described support is by environmental protection high-temperature nylon engineering plastics and copper injection mo(u)lding; Scribble insulating cement on described support, described chip attach is on described insulating cement, described the first gold thread one end is connected with chip, the described first gold thread other end is connected with the positive pole of support, described the second gold thread one end is connected with chip, the described second gold thread other end is connected with the negative pole of support, and described colloid sticks on described support, and described chip, described the first gold thread, described the second gold thread and described insulating cement all are wrapped in inside by described colloid.
As further improvement of the utility model, described insulating cement height is less than described chip height.
As further improvement of the utility model, described insulating cement height is greater than 1/3 of chip height, and described insulating cement height is less than 2/3 of chip height.
As further improvement of the utility model, described rack surface is coated with silver.
As further improvement of the utility model, described colloid is silica gel.
The beneficial effects of the utility model are: the bonded LED lamp pearl with two gold threads of the present utility model is simple in structure, is beneficial to the manufacturing, saves cost.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
As shown in Figure 1, the utility model discloses a kind of bonded LED lamp pearl with two gold threads, comprise support 1, chip 5, the first gold thread 3, colloid 2, described support 1 is by environmental protection high-temperature nylon engineering plastics and copper injection mo(u)lding; Scribble insulating cement 6 on described support 1, described chip 5 is bonded on described insulating cement 6, described the first gold thread 3 one ends are connected with chip 5, described first gold thread 3 other ends are connected with the positive pole of support 1, described the second gold thread 7 one ends are connected with chip 5, described second gold thread 7 other ends are connected with the negative pole of support 1, and described colloid 2 sticks on described support 1, and described chip 5, described the first gold thread 3, described the second gold thread 7 and described insulating cement 6 all are wrapped in inside by described colloid 2.
Described insulating cement 6 height are less than described chip 5 height.This guarantor's high-temperature nylon is called again PPA, and PPA has good injection molding, can carry out simultaneously after goods that processing is as bonding in ultra-sonic welded, twice injection moulding, sticker, laser marking, hot riveting, cutting thread, plating and machine work.
Described insulating cement 6 height are greater than 1/3 of chip 5 height, and described insulating cement 6 height are less than 2/3 of chip 5 height, this insulating cement 6 can bond chip 5 and fix, and by being arranged so that in the situation that use minimum insulating cement 6 of insulating cement 6 and chip 5 height ratio, can be more firm chip 5 is fixed.
By colloid 2, chip 5, the first gold thread 3, the second gold thread 7 and insulating cement 6 are encapsulated on support 1.
This first gold thread 3 and the second gold thread 7 play the effect of conduction, and under the voltage effect, this chip 5 can be luminous.Described support 1 surface is coated with silver.Described colloid 2 is silica gel.
LED lamp pearl of the present utility model is simple in structure, is beneficial to the manufacturing, saves cost.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
