Abstract

The utility model discloses a three-in-one full-color piranha LED lamp which comprises a packaging body and four pins, wherein a bracket is packaged in the packaging body, R, G and B chips are fixedly attached on the bracket, and the chips are electrically connected with the pins. The full-color LED lamp can replace a paster-type LED lamp and a traditional three-in-one full-color LED light source, is applicable to a high-definition display screen and capable of obtaining better lighting effect, has more beautiful appearance, and is convenient for batch production.

Description

A kind of three-in-one full-color Piranha LED lamp

Technical field

The utility model relates to a kind of photoelectric display device, particularly a kind of three-in-one full-color Piranha LED lamp of RGB that adopts.

Background technology

At present, surface mount LED uses flexible design, has shown in the market at LED and has occupied certain share, and accelerated development trend is arranged.The three-in-one full-color display that uses on the market admittedly with three kinds of light emitting sources of RGB, is put glue generally by the synthetic window of pcb board and plastic closure on the pcb board then in the window that pcb board and plastic closure synthesize.This adopting surface mounted LED is non-watertight can only be in interior use, and because the surface of its plastic closure is smooth, adds upper surface and need brush printing ink, thereby causes the excessive luminosity of angle of the light that three kinds of light sources of RGB send lower; In addition, the silk-screen black ink makes the product colour uniformity of producing relatively poor, and needs the hand picking aberration, cause complex manufacturing, and cost is than higher.

Another LED that is used for outdoor serial display screen adopt 2 redness, 1 green, 1 blueness (2R, 1G, 2B) totally 4 LED lamp be combined as full-color spot light, the All colour light source of this Three kinds of hors d'oeuvres one uses the quantity of LED more, the combination cost is higher, and manufacturing process is loaded down with trivial details, only be suitable for LED display, can not be used for the little high definition LED display screen of pixel than the elephant vegetarian refreshments.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide that a kind of illumination effect is good, the simple three-in-one full-color Piranha LED lamp of production technology.

The utility model is to address the above problem the technical scheme that is adopted to be:

A kind of three-in-one full-color Piranha LED lamp comprises packaging body and four pins, is packaged with support in the described packaging body, and admittedly with R, G, three kinds of chips of B, described chip and described pin are electrically connected on the described support.

Further, described rack surface is a bowl cup-shaped, at the bottom of described chip invests bowl admittedly.

Further, described packaging body profile is oval or circular.

The beneficial effects of the utility model are: three kinds of chips are invested on the same support admittedly, can replace the All colour light source of adopting surface mounted LED and Three kinds of hors d'oeuvres one, illumination effect is good, is applicable to the high-definition display screen than small pixel, not only simplified production technology, and can save production cost; In addition, adopt bowl-shape support, thereby the lighting angle that can reduce light source has increased luminosity, make LED have good illumination effect, with its profile be designed to ellipse or circular can make light emitting source solve human body from positive 15 degree with below 30 degree produce the problem of blind area blank when watching outdoor display screen, and then make from each angle and watch display screen all to have preferable effect.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cutaway view of the inner bowl cup of the utility model support;

Fig. 3 is the structural representation of embodiment one of the present utility model;

Fig. 4 is the structural representation of embodiment two of the present utility model.

The specific embodiment

Referring to figs. 1 through Fig. 2, three-in-one full-color Piranha LED lamp of the present utility model comprises packaging body 1 and four pins 2, is packaged with support 3 in the described packaging body 1, and admittedly with R, G, three kinds of chips of B, described chip and described pin 2 are electrically connected on the described support 3.Change traditional red, green, blue Three kinds of hors d'oeuvres one and form the structure of All colour light source, three kinds of led chips are attached on the same support 3, make it to be more suitable for being used on the outdoor display screen of higher pixel point, not only make the all-colour LED light source have good illumination effect, and can conservation and cost, simplify production technology.

As preferred implementation, described support 3 surfaces are a bowl cup-shaped, at the bottom of described chip invests bowl admittedly 31.The rack surface punch die is become the bowl cup, form a reflector, then solid three kinds of light emitting sources of attached RGB at the bottom of cup by the little bowl end 31 and big the rim of a bowl 32.The effect of reflector is to collect the light that chip sides is sent, and makes it to launch in the deflection of expectation, makes the light source of support 3 the insides to reflect by the wall of cup of support 3 like this, thereby luminous intensity is increased.

Described packaging body 1 profile is oval or circular.Thereby the shape of packaging body 1 mould grain can design the brightness that improves light emitting source according to different angles, is preferably ellipse herein.Oval profile makes light increase the angle of departure of light when the packaging body surface is penetrated, corresponding visual angle will increase, solved human body from positive 15 degree with below 30 degree produce the problem of blind area blank when watching outdoor display screen, thereby make the effect of watching from each angle preferable, and contour structures better appearance.

With reference to Fig. 3, be the structural representation of the utility model embodiment one, described pin 2 is the direct insertion pin that exposes.The pin that exposes of described support 3 is more suitable for doing direct insertion application, can help doing waterproof effect tactic pattern preferably.

Fig. 4 is the structural representation of the utility model embodiment two, and described pin 2 also can be the SMD pin of clubfoot.Pin 2 clubfoots are become the application of the adopting surface mounted LED of SMD alternative existing P CB plate and plastic closure, and volume is little, is convenient to miniaturization production, need not ink for screen printing, can simplify production process, save production cost.

In addition, described packaging body 1 is the transparent epoxy resin packaging body.Before epoxy resin is also uncured, insert the support 3 of solid three kinds of light emitting sources of attached good RGB, just formed a three-in-one full-color Piranha LED lamp, can protect inside chip etc. not to be subjected to extraneous the erosion.Packaging body 1 surface is a transparent part entirely, can reflect light source comprehensively, improves the light outgoing efficient of chip, uses lower cost just can reach good illumination effect.

In a word, the utility model has solved the problem that the adopting surface mounted LED colour consistency is relatively poor, need hand picking aberration, complex manufacturing, and alternative traditional Three kinds of hors d'oeuvres one All colour light source, be applicable to the outdoor display screen that pixel is littler, has good illumination effect, can save production cost, be conducive to practical and popularization on a large scale.
