Benefits of technology

[0006]The primary object of the present invention is to provide a three-dimensional miniaturized power supply such that by constructing at least two independent circuit boards in a three-dimensional spatial form, an area and a volume of the power supply can be miniaturized that it can be emplaced in a container at a bottom end of an LED illumination module.

Problems solved by technology

As the dangerous low voltage primary side circuit B along with its electronic elements, and the safe low voltage secondary side circuit C along with its electronic elements are all constructed on the surface of the single circuit board A, the area and a volume of the circuit board A will be large and therefore, it will be difficult to emplace the circuit board A of that power supply into a container with a smaller space.

Abstract

A three-dimensional miniaturized power supply is composed of at least two of a first circuit board and a second circuit board which are assembled in a chamber of a container in a three-dimensional spatial form, wherein an insulation spacing, which is in compliance with an ITE safety regulation, is provided between a circuit of the first circuit board and a circuit of the second circuit board, allowing an area and a volume of the power supply to be miniaturized, such that the power supply can be emplaced in a small container.

Description

BACKGROUND OF THE INVENTION[0001]a) Field of the Invention[0002]The present invention relates to a three-dimensional miniaturized power supply, and more particularly to a power supply wherein a primary side circuit is installed on an independent circuit board, a secondary side circuit is installed on another independent circuit board, and the two circuit boards are assembled in a three-dimensional form, such that an entire volume of the circuit boards after being assembled can be diminished to be emplaced in a chamber of a container; and at a same time, a space which is in compliance with an ITE (Information Technology Equipment) insulation spacing regulation is provided between the primary side circuit and the secondary side circuit.[0003]b) Description of the Prior Art[0004]A circuit board A of a conventional power supply is shown in FIG. 13, wherein the circuit board A can be in a rectangular or a round shape, with its dangerous low voltage primary side circuit B and a safe low v...
