ABSTRACT:
An improved light emitting diode display includes a printed circuit board, a reflector and one or more LED chips. The printed circuit board serves as a base to fix the LED chips and the reflector has an appropriate thickness, contains one or more bowl-like reflective surfaces each with a corresponding passing hole located at such position as close to the bowl-like reflective surface as possible. The bowl-like reflective surface are just big enough to hold one LED chip, with the LED electrode connecting wire extending out of the bowl-like reflective surface and passing through the passing hole to be fixed to the printed circuit board. The small size of the reflective surface permits increased convergency and intensity of the reflective light emitted by the LED chips.
