The first and second sub-lines are connected to the LED elements, so that sufficient current can be supplied to the LED elements in each closed loop, so that all the LED elements can maintain sufficient and uniform even at a current of about 3 mA mA. brightness. Since the LED elements of the planar light-emitting device or the planar backlight module are arranged differently, in the case of the keyboard backlight module, since the button elements are also arranged in a matrix, the electrical insulating plate of the double-panel embodiment is in the first matrix main line. Each closed loop is formed with a component combination perforation corresponding to the position of the button component, which can be conveniently used in the keyboard as a backlight module; and if used in a backlight device such as a steam or locomotive instrument panel, the double-sided circuit board is used. The first and second matrix shapes can be changed to the double-sided line points along with the position of the LED elements, and in summary, the parallel lighting circuit and the board provided by the present invention do improve the unevenness of the parallel type lighting device. The lack of brightness still has the advantage of low power consumption of the parallel lighting circuit.

The closed-loop circuit (4) is for the electrical connection of the LED components, that is, the circuit of the towel is electrically connected with the pin of the LED component, and the plurality of second sub-circuits are electrically connected with the other components of the LED component; The first and second matrix main lines are connected to the power line on the connecting piece, and when the DC power is turned into the power line, a uniform current can be formed in the first and second matrix main lines, and each closed ring The circuit provides a plurality of first and t-th sub-wires 4 connected to the LED elements, so that sufficient current can be supplied to the LED elements in each of the closed % channels, so that all of the LED elements can be maintained at a current of about 3 mA or so. Sufficient and uniform brightness. [Embodiment] Referring to the first figure, the parallel light-emitting circuit (1〇) of the present invention includes: a plurality of LED elements (11), each of which has two electrodes; in the embodiment, each LED The component is a wafer type LED component; a DC power terminal block (12) includes two power terminals for connection with an external DC power source; one of the two power terminals is a positive potential power terminal, and the other is a low potential power terminal. a plurality of first lines (13), one end of each of the first lines (13) is connected to one of the electrodes of the corresponding LED element (11), and the other end is commonly connected to one of the power sources of the DC power terminal block (12) a terminal; in the embodiment, the first line is connected to a positive potential power terminal; and the plurality of first lines (14) 'one second line (14) is connected at one end to the other electrode of the corresponding LED element (11), and The other end is connected to the other power supply terminal of the DC power terminal block (12), so that all the LED elements (11) phase, the power supply line (24) (25) on the M366176 k are connected, and the single LED component is connected to the present. Create a double-sided circuit board (20 ), the positive and negative potential pins respectively pass through two lines to their corresponding first and second matrix main lines. If the line widths of the first and first matrix main lines (22) are added, the design can be further designed. When the first and second sub-lines (222) (223) are wide, a more uniform current can be formed in the first and second matrix main lines, and the first and second sub-lines are provided by the closed loops. By connecting to the LED elements, sufficient current is supplied to the LED elements in each closed loop, so that all of the LED elements maintain sufficient and uniform brightness even at a current of about 3 mA. Since the LED elements of the planar light-emitting device or the planar backlight module are arranged differently, in the case of the keyboard backlight module, since the button elements are also arranged in a matrix, the electrically insulating plate of the double-panel embodiment is in the first matrix main line. Each closed loop is formed with a component combination perforation corresponding to the position of the button component, which can be conveniently used in the keyboard as a backlight module; and if used in a backlight device such as a steam or locomotive instrument panel, the double-sided circuit board is used. The first and first matrix shapes can be shaped as the LED elements are placed. In summary, the parallel light-emitting circuit and the double-sided circuit board provided by the present invention do not have the disadvantage of improving the uneven light-emitting luminance of the parallel light-emitting device, and still have the advantages of low power consumption of the parallel light-emitting circuit.
