Abstract

The utility model provides an LED support. According to the LED support, because metal plates included by the support are bent for many times, the distance of moisture penetration from the outside through the metal plates is increased and the rate is reduced, so that a functional failure caused by a ''blind point'' phenomenon of the product can be prevented. Moreover, an LED surface-mounted module that is manufactured by utilizing the LED support as well as an LED display screen manufactured by the LED surface-mounted module are also provided by the utility model. Waterproof, moistureproof and dustproof problems can be solved well and the thickness of the LED surface-mounted module can be increased according to the demand of the customer; and consistency can be maintained after a mask is pasted.

Description

A kind of LED display, LED surface-mount module and support thereof

Technical field

The utility model relates to the LED technical field, relates in particular to a kind of led support.

Background technology

Along with the development of lighting technology nowadays; Shortcoming is replaced by the LED lamp conventional incandescent just gradually because highly energy-consuming, photoelectric conversion rate be low etc., compares with traditional incandescent lamp, and the LED light fixture has that power consumption is low, spotlight effect good, reaction speed is fast; Power can withstand shocks; Advantage such as long service life, environmental protection, and the led support indispensable assembly that is LED, its importance is self-evident.

Yet in the use of reality, particularly under out of doors the environment, suffer that very easily moisture infiltrates, make product " blind point " occur, cause functional inefficacy.And thickness of product has influence on it when increasing and mounts, and makes waterproof, protection against the tide, the dustproof effect of product weaken, and has reduced the life-span of product, has also influenced the demand that increases product thickness according to client's wish.

Summary of the invention

The purpose of the utility model provides a kind of LED support, solves the problem that traditional LED support is in use infiltrated by moisture easily.

For realizing that above-mentioned purpose the utility model provides following technical scheme:

A kind of support of LED Surface Mount product comprises metallic plate and a reflection of being used separately as positive and negative electrode more than two; Said metallic plate bending respectively repeatedly forms solid brilliant section, bending linkage section and bonding wire section; Wherein, said solid brilliant section places the inside of said reflection, and the bonding wire section exposes outside outward.

Further, said each bending of two metallic plates four times forms three bending linkage sections, in said reflection, is oppositely arranged, and end view is " protruding " font.

Further, the said first bending linkage section exposes to said reflection.

Further, said two metallic plates and reflection are injection molded into one.

A kind of LED surface-mount module comprises LED wafer and said led support, and said LED wafer is fixed on the said solid brilliant section.

Further, the inner glue of filling of said reflection.

Further, said glue is epoxy resin or silicones.

A kind of LED display comprises screen body and casing, and said screen body comprises a plurality of described LED surface-mount modules.

Further, embedding has marine glue between said each adjacent LED surface-mount module, marine glue sealing exposed metal pin part.

Further, the LED surface-mount module of said screen body also is provided with face shield outward.

The beneficial effect of the utility model is:

Because the metallic plate of led support has been taked the method for a plurality of bendings, make moisture infiltrate and elongated along the distance of metallic plate arrival led chip by the junction of said metallic plate and said reflection, permeating speed is slack-off; Anti-permeability is better; Avoid product to produce " blind point " because of moisture infiltrates, caused functional inefficacy, and mounting in the process at product; Even said LED surface-mount module increases certain thickness according to customer requirement; Still can guarantee that said metallic plate exposes to said reflection outer body and can made it be unlikely to as prior art, partly to be exposed in the air by the sealing fully of embedding marine glue institute, both satisfy client's demand; Also play good waterproof, protection against the tide, dustproof effect; And the increase of thickness can also provide enough space mounting plastic cement face shields, guarantees the display screen surface consistency, reaches effect elegant in appearance.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

Embodiment 1

As shown in Figure 5; The LED support that the utility model provides has a reflection 2, a pair of mutual opposed metallic plate 1 (also can be two or three pairs of, according to the LED wafer of required setting what and decide); Reflection 2 has an opening; Like Fig. 7 and shown in Figure 8, described opening 8 is square (also can be circle), described pair of metal plate 1 each bending four times; Form bonding wire section 3, first bending section 4, second bending section 5, the 3rd bending section 6, solid brilliant section 7; Wherein first bending section 4 exposes to said reflection 2, and " protruding " font, said pair of metal plate 1 is injection molded into one with said reflection 2 in described pair of metal plate 1 mutual opposed lateral side view formation.

Obviously,, be not limited to four times to the bending times of metallic plate 1, the amount doesn't matter, can obtain the better effect of impermeable effect with respect to prior art.

Embodiment 2

This embodiment provides a kind of LED table dress module, and is as shown in Figure 6, is on the led support basis that embodiment 1 provides; On its described solid brilliant section 7, install led chip 9; And with epoxy resin 10 embeddings (also can use the silicones embedding), in led chip is wrapped in, with respect to Fig. 1 and prior art shown in Figure 2; The LED table dress module that present embodiment provided is because adopted the led support of embodiment 1; Make moisture extend along the distance of metallic plate 1 infiltration, speed is slack-off, and anti-permeability is better.

Embodiment 3

This embodiment provides a kind of LED display, and is as shown in Figure 9, is on the LED table dress module basis that embodiment 2 provides; Described LED table dress module is welded on the wiring board 11, and in embedding between each LED table dress module marine glue, described first bending section 4 is sealed in the marine glue 12; Play waterproof, protection against the tide, dustproof effect; Cover the plastic cement face shield at last, with respect to Fig. 3 and prior art shown in Figure 4, even the LED display that present embodiment provided is after LED table dress module thickness increases; Its first bending section 4 that exposes still can be sealed by marine glue; Make it can satisfy the demand of client, enough space mounting plastic cement face shields can also be provided, guarantee the display screen surface consistency thickness.

Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the utility model person of ordinary skill in the field; Under the prerequisite that does not break away from the utility model design; Can also make some being equal to substitutes or obvious modification, and performance or purposes are identical, all should be regarded as belonging to the protection range of the utility model.
