<p>An LED driving apparatus, an LED lamp and an LED driving method. The LED driving apparatus includes a wireless receiving module (100) and an LED driving module (140) which are communicatively connected via a digital interface (124); the wireless receiving module (100) comprises a main control module (101) and a wake-up module (102) which are connected to each other; the wake-up module (102) sends out a sleep/wake-up control signal so as to enable the main control module (101) to work in a sleep mode and a wake-up mode at a predefined time interval; the main control module (101), in the wake-up mode, views whether a control instruction is received, if so, a digital control signal is generated and sent to the LED driving module (140); and the LED driving module (140) includes a latching unit, and the LED driving module (140) generates a driving current and/or voltage for supply to an LED lamp group (150). The driving apparatus enables the wireless receiving module to be in the sleep mode for a long time, and only switches between the sleep mode and the wake-up mode at the predefined time interval. When the wireless receiving module is in the sleep mode, the high temperature generated by the LED lamp group will not affect the life of the wireless receiving module, thereby improving the life of the LED driving apparatus.</p> |
