LED package structure of LED display

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to FIG.
1, wherein an LED lamp 1 constructed in accordance with the present invention is shown, the LED lamp 1 comprises two metallic leads 10 and 11.
One of the metallic leads, for example lead 10, has reflector means 12 integrally formed thereon by means of, for example a pressing technique.
The reflector means 12 comprises a bowl-shaped concave reflecting surface 121, preferably a portion of a paraboloid in which defines a focus point F (see FIG.
11) along an optical axis extending from the center L (see FIG.
11) thereof.
A stand member 13 is formed on the center L of the reflecting surface 12 and extending toward the focus point F to have a top end thereof on a location substantially coincident with the focus point F.
Both the reflecting surface 12 and the stand member 13 may be formed simultaneously at the same pressing process.
An LED die 14 is mounted on the top end of the stand member 13.
The LED die 14 has a connector pad (not shown) mounted thereon for the electrical connection with a conductive lead 15 to another frame 11.
The structure is then encased by a resin enclosure 16 with only the metallic frames 10 and 11 partially projecting out of the enclosure 16.
The structure has the advantage of positioning the LED die 14 at the focus point F of the reflector means 12 by mounting the LED die 14 on the stand member 13 so that the reflecting surface 121 can extend further toward the position of the center L thereof to provide a more efficient reflecting surface and increasing the luminance of the LED lamp 1.
This structure is also applicable to a dot matrix LED display which is disposed on a PCB base.
Conventionally, the dot matrix LED display has a rivet extending out therefrom, such as that 94 shown in FIG.
9, just for electric connecting to a mother board of the display system.
These rivets are for connecting purpose only.
In accordance with an aspect of the present invention, the rivets will be modified to serve as LED die supporting means
