Description

A kind of dual-colored LED structure

Technical field

The utility model relates to a kind of LED, and the dual-colored LED knot of two kinds of colors can be simultaneously emitted by more particularly, to one kind Structure.

Background technique

LED is the novel product for nowadays being used to replace the lighting apparatus of incandescent lamp and other old-fashioned high energy consumptions in the market, It is not only small in size, but also energy consumption polar region, while also having better color and luminous intensity adaptability, can satisfy society now The requirement of meeting diversification.In existing LED, mainly 2835 and 5,050 two kind of specification it is most commonly used, but double In the LED of color, carried out using two LED chips it is luminous, but when these LED shine, it may occur that the problem of colour contamination.Needle For the use environment and requirement of some LED, the phenomenon that needing LED to reduce colour contamination as far as possible when luminous.And existing LED Structure in, can not effectively solve the above problems.

Utility model content

The technical issues of the utility model solves is to provide a kind of dual-colored LED structure, effectively reduces dual-colored LED when luminous Colour contamination phenomenon.

The technical solution of the utility model is:

A kind of dual-colored LED structure, wherein including plastic seat, pad, luminescence chip, stitch and barrier wall, the plastic seat Interior to be equipped with groove, middle section is equipped with barrier wall in the groove, and the barrier wall two sides are respectively equipped with pad, the barrier wall LED chip is connected separately on the pad of two sides, the barrier wall is made of white light light blocking material；The height of the barrier wall is big In 0.9mm.

Dual-colored LED structure as described above, wherein the barrier wall is the string configuration with trapezoidal cross-section, Bottom width is 0.44mm, top width 0.16mm, height 0.95mm.

Dual-colored LED structure as described above, wherein the edge of the pad is equipped with the stairstepping knot of part perpendicular to the sag Structure.

Dual-colored LED structure as described above, wherein the stitch through the plastic seat bottom is equipped with below the pad.

Dual-colored LED structure as described above, wherein the stitch is tabular stitch identical with the bonding pad area.

It is learnt by described above, compared with prior art, can reach following effect really:

The dual-colored LED structure of the utility model, design have novel barrier wall construction, are set by the barrier wall of height Meter changes the illumination path range that light issues after LED shines, meanwhile, white light light blocking material is used, is preferably completely cut off The light transmission possibility of barrier wall.In addition, the utility model additionally uses stepped pad peripheral structure, effectively prevent welding It is easy the problem of short circuit, and also further improves the ability of bend resistance.

Specific embodiment

For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention Specific embodiment of the present utility model.

A kind of dual-colored LED structure of the utility model, in preferred embodiment, please refer to Fig.1 to Fig.3 shown in, it is described Dual-colored LED structure includes plastic seat 1, pad 3, luminescence chip, stitch 4 and barrier wall 2, is equipped with groove, institute in the plastic seat 1 It states middle section in groove and is equipped with barrier wall 2,2 two sides of barrier wall are respectively equipped with pad 3, the weldering of 2 two sides of barrier wall LED chip is connected separately on disk 3, the barrier wall 2 is made of white light light blocking material；The height of the barrier wall 2 is greater than 0.9mm.The dual-colored LED structure of the utility model separates two LED chips using barrier wall 2 in the groove in plastic seat 1, The height of the barrier wall 2 reaches 0.9mm or more, so that inclined Sidewall angles become smaller, optical path direction of illumination is more vertical；In addition It is made of white light light blocking material, can more effectively obstruct the light of two LED chips, reduce the generation of colour contamination problem.

The dual-colored LED structure of the utility model as described above, in preferred embodiment, the barrier wall 2 be with The string configuration of trapezoidal cross-section, bottom width 0.44mm, top width 0.16mm, height 0.95mm. The dual-colored LED structure of the utility model, the formation trapezoidal cross-section structure of different size of 2 top and bottom of barrier wall are high Degree is set as 0.95mm, has the plastics holder structure of more big height for a kind of more existing LED, so that trapezoidal side wall inclines Gradient increases, and changes the luminous optical path of LED, preferably can prevent optical path from intersecting, reduce colour contamination.

The dual-colored LED structure of the utility model as described above, in preferred embodiment, the edge of the pad 3 is set There is the ladder-type structure 5 of part perpendicular to the sag.In 1 groove of plastic seat of the dual-colored LED structure of the utility model, bottom surface is covered There is pad 3, and the periphery of the pad 3 all has stepped structure, it is disconnected that the structure of the step type can effectively reduce bending It splits, and also can preferably avoid the problem that solder shorts.

The dual-colored LED structure of the utility model as described above in preferred embodiment, is equipped with below the pad 3 Stitch 4 through 1 bottom of plastic seat, forms the structure for extending vertically through 1 bottom of plastic seat.4 energy of stitch as described above It is enough to be directly connected to pad 3, it prevents the case where leading to poor contact because of situations such as bending, meanwhile, this vertical structure can subtract Few 1 bottom thickness of plastic seat.

The dual-colored LED structure of the utility model as described above, in preferred embodiment, the stitch 4 be with it is described The identical tabular stitch 4 of 3 area of pad.The area of the stitch 4 is corresponding with the area of the pad 3, then pad 3 can be more The problems such as more fully connecting with stitch 4 well, preventing fracture, directly can also be produced LED chip by the stitch 4 of large area Raw heat directly conducts, and significantly reduces the heating temperature of LED at runtime.

The dual-colored LED structure of the utility model, design have novel barrier wall construction, are set by the barrier wall of height Meter changes the illumination path range that light issues after LED shines, meanwhile, white light light blocking material is used, is preferably completely cut off The light transmission possibility of barrier wall.In addition, the utility model additionally uses stepped 3 peripheral structure of pad, effectively prevent welding The problem for being easy short circuit is connect, and also further improves the ability of bend resistance.Secondly it there are also the design of stitch vertical structure, reaches To better reduced thickness and heat dissipation effect.

The above descriptions are merely exemplary embodiments of the present utility model, the model being not intended to limit the utility model It encloses.Any those skilled in the art, made equivalent change under the premise of not departing from the conceptions and principles of the utility model Change and modify, should belong to the range of the utility model protection.
