Embodiment
With concrete embodiment the present invention is done explanation further below.
See also Fig. 1, the illuminating module 10 that first embodiment of the invention provides comprises 8 luminescence unit D11, D21, D31, D41, D12, D22, D32, the D42 that matrix form is arranged.At this, these 8 luminescence units are arranged into 4 row, 2 row.Luminescence unit D11, D21, D31, D41 are sequentially arranged in 4 row of first row; Luminescence unit D12, D22, D32, D42 are sequentially arranged in 4 row of secondary series.Said luminescence unit can be light-emitting diode, laser diode or bulb.
The positive pole of 4 luminescence unit D11 of first row, D21, D31, D41 links together and forms the positive pole of illuminating module 10, and the negative pole of 4 luminescence unit D12 of secondary series, D22, D32, D42 links together and forms the negative pole of illuminating module 10.And the luminescence unit D22 of the luminescence unit D11 of the first row odd-numbered line, the negative pole of D31 and secondary series even number line, the positive pole of D42 electrically connect; The luminescence unit D12 of the luminescence unit D21 of the first row even number line, the negative pole of D41 and secondary series odd-numbered line, the positive pole of D32 electrically connect.
When between the positive and negative electrode of illuminating module 10, applying corresponding driving voltage or drive current, all luminescence units in the illuminating module 10 will operate as normal and are luminous.
If one of them luminescence unit, open circuit and damage like D11, the electric current of the D11 that flows through will change by the luminescence unit D31 that flows through, and makes luminescence unit D22, the D42 still can operate as normal.In addition, the operate as normal of luminescence unit D21, D41, D12, D32 can not receive the influence that D11 opens circuit.
If one of them luminescence unit damages like the D11 short circuit, the positive and negative end of luminescence unit D31 will be similar to by the lead short circuit so, thereby can not be normally luminous.But luminescence unit D22, D42 still can operate as normal.Simultaneously, luminescence unit D21, D41, D12, D32 also can operate as normal and can not receive the influence of D11 short circuit.
As stated, no matter luminescence unit D11 opens circuit or short circuit, can not influence the luminescence unit D21 that is adjacent and the operate as normal of D12.Therefore, this arrangement mode of luminescence unit helps solving when a luminescence unit damage, with its all can not be normally luminous with the luminescence unit of delegation or same row and cause the problem of blanking bar.
Further, illuminating module can comprise that also resistance unit is in order to the electric current of control through each luminescence unit.As shown in Figure 2; The illuminating module 20 of second embodiment of the invention further comprises a resistance unit 21; This resistance unit 21 is connected in series with whole illuminating module 10, crosses the electric current of each luminescence unit in the illuminating module 10 in order to control flows, thereby controls the luminous intensity of illuminating module.
