Description of the Invention: [Technical Field] The present invention relates to a light-emitting module, and more particularly to a light-emitting diode light-emitting module. [Previous Technology Broadcasting] [0002] A Light Emitting Diode (LED) is a semiconductor element that converts current into light of a specific wavelength range. The light-emitting diode is widely used in the field of illumination because of its high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life. [0003] In an illumination device having a plurality of light-emitting diodes, the light-emitting diodes are generally connected in series to form one branch, and then a plurality of identical light-emitting diode branches are connected in parallel to an external power source. The external power source is used to supply a driving voltage or a driving current to the light emitting diodes to cause the plurality of light emitting diodes to emit light. However, if one of the light-emitting diodes of the lighting device fails and is disconnected, the other light-emitting diodes of the branch will also be extinguished without passing current. Therefore, a strip-shaped non-light-emitting area, called a dark strip, will be formed in the illumination device. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a light-emitting module in which other light-emitting units can still operate normally after one light-emitting unit is damaged. [0005] A lighting module is composed of a plurality of light emitting units arranged in a matrix. The light-emitting units are arranged in m rows and n columns, wherein m and n are each an integer greater than one. The positive poles of all the light-emitting units in the first column are electrically connected together to form the positive pole of the light-emitting module, and the negative poles of all the light-emitting units in the last column are electrically connected to 099122916. Form No. 1010101 Page 4/18 pages 0992040385-0 201204165 [0006] Ο [0007] Ο [0008] [0009] 099122916 Connected to form the negative pole of the light-emitting module. The dipoles of all the odd-numbered rows of the light-emitting elements in the ... are electrically connected to the positive electrode of the illuminating unit with the even-numbered illuminating unit; the illuminating unit of all the even-numbered rows in the column and the illuminating unit of the odd-numbered rows in the column The positive electrode is electrically connected, wherein i is an integer less than n. A light-emitting device includes a power supply and a plurality of the light-emitting modules arranged in a matrix. The same-line lighting modules are connected in series to form a series branch. The "news" of each row of the turn-up groups are connected in parallel between the positive and negative electrodes of the power supply. Compared with the prior art, the present invention uses the negative poles of the light-emitting units of the odd-numbered rows in each column and the even-number of the lower-column The positive electrode of the row of the Wei unit is electrically connected, and the anode of the light-emitting unit of the even-numbered row in each column is electrically connected to the anode of the odd-numbered row of the light-emitting unit of the next row to form a staggered connection circuit structure. If one of the light-emitting units fails or is short-circuited or disconnected, it does not affect the normal illumination of the adjacent light-emitting unit, so that the light-emitting module of the present invention does not have a regional dark band, thereby improving The present invention will be further described in detail with reference to the specific embodiments. Referring to FIG. 1, a lighting module 1A according to a first embodiment of the present invention includes eight illuminations arranged in a matrix. Units D11, D21, D31, D41, D12, D22, D32, D42. Here, the eight light-emitting units are arranged in four rows and two columns. The light-emitting units D11, D21, D31, and D41 are sequentially arranged. Listed in the 4 rows of the first column; the light-emitting units D12, D22, D32, D42 are sequentially arranged in 4 rows of the second column. The light-emitting unit may be a light-emitting diode, a laser diode or a form number AQ101 5 pages / total 18 I 0992040385-0 201204165 light bulbs. [0010] The positive poles of the four light-emitting units D11, D21' D31, D41 of the first column are connected together to form the positive pole of the light-emitting module 10, and the fourth column The negative electrodes of the light emitting units D12, D22, D32, and D42 are connected together to form a negative electrode of the first module 1〇, and the negative electrodes of the first row of the odd-numbered rows of the light-emitting units D11 and D3i and the second row of the even-numbered rows of light-emitting units are The anode of D42 is electrically connected; the cathodes of the light-emitting units D21 and D41 of the first row of even rows are electrically connected to the anodes of the light-emitting units D12 and D32 of the second row of odd rows. [0011] When a corresponding driving voltage 戍 driving current is applied between the positive and negative electrodes of the light emitting module 1 ,, all the light-receiving elements in the light-emitting module 10 will normally operate to emit light. [0012] If one of the light-emitting units 'such as D11 is broken and the current flowing through d 11 will flow through the light-emitting unit D31, the light-emitting units D22 and D42 can still operate normally. In addition, the normal operation of the 'light-emitting units D21, M1, D12, D32 is not affected by the Dll break: the way. [0013] If one of the light-emitting units 'such as D l 1 is short-circuited and damaged 43⁄4, then the light-emitting unit: :.;: The positive and negative ends of D31 will be similar to being short-circuited by the wires, so that the light cannot be normally emitted. However, the light-emitting units D22 and D42 can still work normally. At the same time, the light-emitting units D21, D41, D12, and D32 can also operate normally without being affected by the short circuit of D11. As described above, regardless of whether the light-emitting unit D11 is turned off or short-circuited, the normal operation of the light-emitting units D21 and D12 adjacent thereto is not affected. Therefore, the arrangement of the light-emitting unit is advantageous for solving the problem that when one light-emitting unit is damaged, the light-emitting unit in the same row or the same column cannot be normally illuminated and made 099122916 Form No. A0101 Page 6 / 18 Page 0992040385-0 201204165 A problem with dark bands.

When the resistance unit is connected, the recording, and the other end are connected together to form the positive electrode of the light-emitting module 3〇. [0017] It can be understood that the above-mentioned resistor unit can also be disposed at the negative end of the light-emitting module as long as it can effectively adjust the current passing through the light-emitting unit. [0018] It can be understood that the number of rows of the light-emitting unit is arranged. The number of columns is not limited by the above embodiments. The light-emitting module 4A shown in Fig. 4 includes light-emitting units arranged in a matrix, and the light-emitting units are arranged in m rows and n columns. The anodes of the first row of light-emitting units are connected together to form a positive electrode of the light-emitting module 4〇; the negative electrodes of the light-emitting units of the last column are connected together to form a negative electrode of the light-emitting module 40. In the present embodiment, the symbol of j) ij is used to indicate the light-emitting unit in the i-th row and the j-th column, where i is an integer not greater than !, and j is an integer smaller than n. The electrical connection relationship of the light-emitting unit is as follows.
