Abstract

The utility model relates to an LED (Light Emitting Diode) lamp, in particular to a full color LED lamp which is used for an LED display screen; the full color LED lamp comprises a red LED wafer, a green LED wafer, a blue LED wafer, a bracket and a reflective cup, wherein four pads are distributed on the bracket, the LED wafers are arranged on the pad and the reflective cup is arranged on the bracket so as to form the full color LED lamp. Aiming at the defect that the light of the LED wafers in the LED bracket structure of the prior art cannot be emitted well, the full color LED lamp of the utility model utilizes the bracket which is provided with four arcs; the LED wafers can be focused at the centre of the cup bottom of the reflective cup, thereby being more useful for focusing light so as to improve the light emitting effect.

Description

A kind of all-colour LED lamp

Technical field:

The utility model relates to a kind of LED display light source, particularly a kind of all-colour LED lamp that is used for LED display.

Background technology:

Along with developing rapidly of LED display, show present LED screen further, show that low gray scale picture effect is not ideal, the contrast of picture does not reach the defective of requirement yet.Existing 3528 all-colour LED lamps are by the isosceles triangle support, the red, green, blue wafer, and glue, gold thread, silver slurry structure forms, and each wafer is formed the pixel of each LED lamp; What adopted the bottom is round bottom, Gu brilliant position is Chinese character pin-shaped, outward appearance is the surface brush China ink.But there is certain drawback in this display mode, because Chinese character pin-shaped display mode sees from the left and right sides angle of display screen, can only see two kinds of colors, and the bright dipping mode of round bottom is not very good, an outward appearance surface brush China ink, and after the lamp pearl was made screen, contrast was bad.

Fine definition and high-contrast are the developing direction of display screen.4 led supports that led light source of the prior art adopts usually (please with reference to accompanying drawing 1 and accompanying drawing 2); The present made light source of 4 led supports all comprises a reflector, 4 pads that are fixedly mounted on the reflector bottom; Four pads are in the reflector rectangular distribution in bottom; Insulated part between four pads is " ten " font, and four pads are separately positioned on one jiao.During use, three LED wafers are separately positioned on the pad, are electrically connected with the 4th pad again.Because reflector 1 inside on the led support of the prior art is truncated cone-shaped and because result's restriction of led support of the prior art, make LED wafer 2 luminous can not well ejaculations, use to receive certain limitation.

Summary of the invention:

The purpose of the utility model is to overcome the deficiency of prior art and a kind of all-colour LED lamp that is used for LED display of inventing.

The purpose of the utility model can be passed through following measure and realized:

A kind of all-colour LED lamp of the utility model comprises redness, green, each a slice of blue led wafer, is distributed with support and reflector of four pads, and the LED wafer is installed on the pad, and reflector is rack-mount, forms the all-colour LED lamp.

Described three LED wafers are installed on the same pad, and the lead-out wire of each LED wafer is electrically connected with the another one pad respectively; The pad of the described LED of being equipped with wafer is arranged on the centre position of reflector bottom.

The pad of the described LED of being equipped with wafer is " " " type, mutually insulated between each pad.

Described three LED wafers are line style to be arranged, and is arranged on middle, reflector bottom.

Described reflector bottom is curved, seamlessly transits to circular rim of a cup, is fixedly connected on the support that is distributed with pad.

A kind of all-colour LED lamp of the utility model to led support structure of the prior art, makes the luminous defective that can not fine ejaculation of LED wafer; Adopting support is four arcs; The LED wafer can concentrate on center at the bottom of the reflector cup simultaneously, helps optically focused more, light effect thereby improve.

The specific embodiment:

For setting forth the design concept of the utility model, will combine the accompanying drawing and the specific embodiment that the utility model is done further explanation below.

A kind of all-colour LED lamp of the utility model comprises redness, green, blue led wafer 2 each a slice, is distributed with support and reflector 1 of four pads 4, and LED wafer 2 is installed on the pad 4, and reflector 1 is rack-mount, forms the all-colour LED lamp.

With reference to Fig. 3, Fig. 4, Fig. 5, three LED wafers 2 are installed on the same pad 4, and the lead-out wire 3 of each LED wafer 2 is electrically connected with another one pad 2 respectively;

The pad 4 that LED wafer 2 is installed is arranged on the centre position of reflector 1 bottom.

The pad 4 that LED wafer 2 is installed is " " " type, mutually insulated between each pad 2.

Three LED wafers 2 are line style to be arranged, and is arranged on middle, reflector 1 bottom.

Reflector 1 bottom is curved, seamlessly transits to circular rim of a cup, is fixedly connected on the support that is distributed with pad 2.

Among Fig. 1, Fig. 2; The present made light source of 4 led supports all comprises a reflector 1 and four 4, four pads 4 of pad that are fixedly mounted on reflector 1 bottom in the rectangular distribution in reflector 1 bottom, and the insulated part between four pads 4 is " ten " font; Four pads 4 are separately positioned on one jiao; During use, three LED wafers 2 are separately positioned on the pad 4, are connected with the 4th pad through gold thread 3 again.Reflector 1 inside on the led support of the prior art is truncated cone-shaped.Because the result of led support of the prior art restriction, make LED wafer 2 luminous can not well ejaculations, use to receive certain limitation.

When implementing the all-colour LED lamp of the utility model; In the middle of three LED wafers 2 can be welded on simultaneously on pad 4, and concentrate on center at the bottom of 1 glass of the reflector, help optically focused more; Improve luminous intensity, improve product and be used in contrast and color developing effect on the display screen.Make reflector 1 bottom curved, rim of a cup is rounded, and the cup end to rim of a cup is for seamlessly transitting.The support that uses is four arcs, and LED wafer 2 can concentrate on center at the bottom of 1 glass of the reflector simultaneously, helps optically focused more, light effect thereby improve.

More than a kind of all-colour LED lamp that the utility model provided has been carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously; For one of ordinary skill in the art, according to the thought of the utility model, the present inventive concept of the utility model can change; And all ins and outs can use equal replacement, and part all can change on the specific embodiment and range of application.In sum, this description should not be construed as the restriction to the utility model.
