Abstract

The utility model discloses an LED bracket. The LED bracket comprises a plastic base and a plurality of conductive pins, wherein the plastic base is provided with a packaging cavity; the plurality of conductive pins are embedded and formed in the plastic base; and the bending direction of welding terminals of the conductive pins exposed out of the plastic base is opposite to the opening direction of the packaging cavity. Accordingly, the welding terminals of the conductive pins extend out of the plastic base in a bending manner, and the bending direction of the welding terminals is opposite to the opening direction of the packaging cavity, a simple structure is achieved, and both the height and the size of the packaging cavity of the product can be adjusted in a space. As the height of the packaging cavity is reduced, and the internal space of the packaging cavity is enlarged, a wafer larger than a traditional one can be packaged on the client side, accordingly, the illumination effect of an LED is effectively enhanced (the luminous flux is increased by more than 15 percent in comparison with a traditional bracket), and the brightness of a display or a display screen can be greatly improved.

Description

Led support

Technical field

The utility model relates to the LED art, refers in particular to a kind ofly can strengthen led support light efficiency and that be applied to display or display screen.

Background technology

Advantages such as light-emitting diode display integrates microelectric technique, computer technology, information processing, and is bright in luster with it, that dynamic range is wide, brightness is high, the life-span is long, working stability is reliable become the display media of new generation of tool advantage.Continuous progress along with large scale integrated circuit and computer technology, light-emitting diode display emerges rapidly, at present, light-emitting diode display has been widely used in large-scale square, commercial advertisement, stadiums, information propagation, news briefing, securities trading etc., can satisfy the needs of varying environment.

As shown in Figure 1, be the concrete structure of the led support of existing display, its include plastic cement seat 10 ' and conductive pin 20 '.Up package cavity 11 of this plastic cement seat 10 ' have opening '.This conductive pin 20 ' produced by insert molding in plastic cement seat 10 ' in, this conductive pin 20 ' welding ends 21 ' through bending extend plastic cement seat 10 ' outside, this welding ends 21 ' wrap direction and package cavity 11 ' opening direction identical, i.e. this welding ends 21 ' bending up.During use, with component package such as led chip and this package cavity 11 ' in, welding ends 21 ' with external circuit is electrically connected gets final product then.

Above-mentioned existing display led supporting structure, though can offer the effect of user's packaged LED, really has progressive, but when using, reality but finds still to have many deficiencies on himself structure and the serviceability, cause existing display led support in practical application, fail to reach best result of use and task performance, now its shortcoming is summarized as follows: because this package cavity 11 ' opening direction and conductive pin 20 ' welding ends 21 ' wrap direction identical, i.e. this package cavity 11 ' towards upper shed, this welding ends 21 ' bending equally up, and the problem of considering to beat the gold thread arc-height, usually the height of package cavity is more than the 0.5mm, the inner chamber width can only accomplish 0.40 (wafer that can't encapsulate bigger one-level as: width is the wafer of 14u), and light efficiency generally can only be accomplished 1300 lumens when this structure was used in reality.

The utility model content

In view of this, the utility model is at the disappearance of prior art existence, and its main purpose provides a kind of led support, its can effectively solve existing led support lumen value when luminous low the problem of LED illumination effect difference.

For achieving the above object, the utility model adopts following technical scheme:

A kind of led support, include plastic cement seat and plural conductive pin, this plastic cement seat has a package cavity, and this plural conductive pin produced by insert molding is in the plastic cement seat, and the wrap direction of the welding ends that is exposed to the plastic cement seat of described conductive pin is opposite with the opening direction of this package cavity.

As a kind of preferred version, described welding ends includes first bending part and second bending part, the wrap direction of this first bending part is opposite with the opening direction of this package cavity, this second bending part is coated on outside the plastic cement seat to a side bending, and this second bending part extending laterally out from first bending part.

As a kind of preferred version, described package cavity is towards upper shed, to should the bending down of first bending part.

As a kind of preferred version, the wrap direction of described second bending part is vertical with the wrap direction of first bending part.

As a kind of preferred version, described insulating base extends laterally limited step, and this limited step is positioned at the top of second bending part.

The utility model compared with prior art has tangible advantage and beneficial effect, particularly, and as shown from the above technical solution:

One, by the welding ends bending of conductive pin is extended outside the plastic cement seat, and utilize the wrap direction of this welding ends opposite with the opening direction of this package cavity, simple in structure, make this product package cavity height and size that adjustable space arranged, and the height by reducing package cavity and increase its inner space, can make the client encapsulation wafer bigger than tradition, thereby effectively strengthen the illumination effect (than the traditional lumen value of support raising more than 15%) of LED, the brightness that can improve display or display screen greatly.

Two, utilize the wrap direction of this welding ends opposite, also can make this product when installing and using, avoid stopping of outer member and disturb, further effectively strengthen the illumination effect of LED, the brightness that improves display with the opening direction of this package cavity.

Three, be provided with limited step by top in second bending part, utilize this limited step that the welding ends of this conductive pin is effectively located, be more convenient for the welding ends of this conductive pin is welded on the external circuit, and make that welding is more firm, promoted the reliability that this product uses.

For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:
