<p>The present invention relates to a driving device (1, 2, N) for an illuminating device, the illuminating device comprising a plurality of sub illuminating units (D12, D22, DN2), the driving device comprises a plurality of sub driving modules (L1, C1; L2, C2; LN, CN) in series connected to an input voltage source to distributively store energy from the input voltage source, each of the sub driving modules (L1, C1; L2, C2; LN, CN) being allocated to and electrically connected with one sub illuminating unit (D12, D22, DN2), so as to release the stored energy of a sub driving module (L1, C1; L2, C2; LN, CN) to the sub illuminating unit (D12, D22, DN2) allocated thereto. According to the present invention, an LED lamp having a small volume can be realized, and the layout of the LED lamp on the circuit board is easier and safer.</p> |
