Resistance balance circuit

Abstract

A resistor balancing circuit is provided with at least two electronic element which are arrayed in a row matrix, and are connected in parallel to form a row matrix structure; an input end provided at one end of the row matrix structure for providing a conducting current for each electronic element in the row matrix structure; and an output end which is arranged on the row matrix structure catercorner with the input end for educing the conducting current for each electronic element in the row matrix structure, wherein, the length of the conducting current, which passes through each electronic element, from the input end to the output end is equal to each other. Because in the resistor balancing circuit of the invention, the input end for providing the conducting current for each electronicelement in the matrix array structure and the output end for educing the conducting current for each electronic element in the matrix array structure are catercorner arranged, the length of the conducting current, which passes through each electronic element, from the input end to the output end is equal to each other, further, electronic elements mounted on each branch of the matrix array structure acquires same conducting current.

Description

technical field [0001] The present invention relates to a resistance balancing circuit, in particular to a resistance that is arranged in a row matrix or a column matrix as a connection structure for electrically connecting at least two electronic components to ensure the uniformity of the conduction current flowing through the electronic components balanced circuit. Background technique [0002] Because light emitting diodes (Light Emitting Diode; LED) have the advantages of high efficiency, long life, and unbreakable advantages that cannot be compared with traditional light sources, they are widely used, such as traffic lights, car lights, table lamps, street lights, billboards and LCD LEDs can be seen in light source equipment such as display backlight modules. [0003] The light source equipment using LED as lighting needs to use a large number of LEDs, thus forming such as figure 1 The LED array structure 1 shown, but due to the difference in the characteristics of ...

Problems solved by technology

However, in order to achieve the uniformity of conduction current, multiple parallel LEDs 140 in the LED package 14 are adjacently arranged, so it is not easy to dissipate heat, and the red, green, and blue color mixing results are easily affected because the multiple LEDs 140 are in parallel structure; , the LED array 15 formed by connecting multiple LED packages 14 in series also has the aforementioned Figure 1 shows the circuit resistance imbalance problem of the LED array structure

[0006] Therefore, how to solve the problem of uneven brightness caused by the unbalanced line resistance of the existing LED array structure, and at the same time overcome the problems of high cost and complicated manufacturing process (process) The problem is actually an urgent problem to be solved when using the LED array structure as the light source equipment
