Abstract
An ellipse LED with diode feet lined along the shorter axial direction and a display screen display module are provided. A metal bracket, a metal concave ring and a diode core which are connected with the cathode diode foot; a metal anode is connected with the anode diode foot. The outer shell of the diode body is an ellipse transparent rubber body. The two diode feet are lined along the shorter axial direction of the ellipse sectional surface. The LED is laid on the LED display screen printed circuit board in such a way that the shorter axial direction of the LED ellipse section is accorded with the height direction H of the printed circuit board, which saves welding areas of the printed circuit board and welding materials. The effects are more obvious when the number of LED is large. Besides, the sizes of the display screen and the printed circuit board can be reduced. The two diode feet are lined along the shorter axial direction so that the LED, which can be declining along the longer axial direction, can be set straight by hand or with a straightening board. Then the light emitting axes of the LED can be vertical to the printed circuit board. The utility model is convenient and labor-saving with not inner stress. Thus the utility model is in particular fit for light concentration LED and outdoor LED display screen.
Description
(1) technical field: the utility model relates to a kind of light-emitting diode and the display screen display module that is used for LED display, belongs to display unit and parts.
(2) background technology: see Fig. 5 and Fig. 6, the existing light-emitting diode N that is used for LED display, anode pin 2a and negative electrode pin 2b are arranged in major axis (X) direction of the oval cross section of transparent colloid 1.5.See Fig. 7, major axis (X) direction that this light-emitting diode N arranges is consistent with the Width B of LED display printed board 3N.This structure has following defective: 1. because major axis (X) direction is the major axis of oval cross section, thus, the pad distributed areas are big in the printed board 3N solder side.When 2. generally being welded in two pin two a and 2b in the printed board, tend to make some light-emitting diode to produce tilt phenomenon (seeing shown in Fig. 5 dotted line) along major axis (X) direction with wave-soldering.Thus, two pin height (Z) direction weld lengths are inconsistent, influence the brightness of light-emitting axis Z direction.Therefore, often need to pull or utilize correcting plate to remove to set upright oval transparent colloid 1.5 with hand after welding, the light-emitting axis Z that makes each light-emitting diode is perpendicular to printed board.But because two pins are arranged in major axis (X) direction, and welded extremely in printed board, can't make the light-emitting diode of inclination pull, set upright along major axis (X) direction, and easily make light-emitting diode produce internal stress, fracture easily, influence the photoelectric characteristic and the life-span of pipe, or pin is fractureed, need manually remove to replace welding pipe.
(3) summary of the invention:
Oval light-emitting diode and display screen display module that the pin that the utility model provides is arranged along minor axis, be exactly to solve the existing arrangement of oval light-emitting diode in printed board, cause pad distributed areas major axis (X) direction big and that be difficult to oval cross section to pull, set upright the problem of the light-emitting diode of inclination, and make light-emitting axis all perpendicular to printed board.Its technical scheme is as follows:
The oval light-emitting diode that pin is arranged along minor axis, be made up of body 1 and pin two, be provided with the metallic support 1.1 that links to each other with negative electrode pin 2b in the body, the metallic support top is the recessed cup 1.2 of metal, place tube core 1.3 in the recessed cup, be provided with the metal anode 1.4 that links to each other with anode pin 2a in the body; The body shell is oval body transparent colloid 1.5; The major axis of oval cross section is a directions X, and minor axis is the Y direction, it is characterized in that anode pin 2a and negative electrode pin 2b arrange along short-axis direction.
With the made display screen display module of above-mentioned light-emitting diode, comprise light-emitting diode, printed board, electronic devices and components, it is characterized in that light-emitting diode arranges as follows in the printed board of display screen display module: the anode pin 2a of light-emitting diode is consistent with the short transverse H of display module printed board (3M) service position with the minor axis Y direction that negative electrode pin 2b is arranged.
The utility model beneficial effect:
I. see Fig. 1, see Fig. 4, whole light-emitting diodes of LED display are selected M for use, and two pins that are arranged in minor axis (Y) direction are arranged as a line along printed board height H direction, and this layout can be saved the distributed areas of solder side pad, save scolder.Especially the display screen that light-emitting diode quantity is big is more outstanding.If arrange the display screen of the light-emitting diode of equal number, the printed board size can reduce.Ii. two pins are arranged in minor axis (Y) direction, can pull, set upright the light-emitting diode of inclination along major axis (X) direction, and the light-emitting axis that makes light-emitting diode is all perpendicular to printed board, and do not produce internal stress, and are laborsaving, convenient.This light-emitting diode is the light-focusing type light-emitting diode, and the LED display of being made by it is specially adapted to outdoor display screen.
