Abstract: An illumination apparatus which comprises a timing module, a control module and a first power conversion module and can be automatically adjusted with time is provided. The timing module sets the time into N sessions, and generates an ith timing signal according to the ith session corresponding to the current time, wherein i and N are natural numbers and i?N. The control module reads the ith timing signal from the timing module, and outputs an ith control signal. The first power conversion module, coupled to an AC power supply, the control module and a first light source, converts the AC power supply signal into a DC power signal and outputs the DC power signal to the control module, and outputs an ith DC driving signal to drive the first light source to emit light of the ith situation after receiving the ith control signal.

Abstract: A current limiting device includes a constant current source circuit constructed and arranged to be connected to a direct current input voltage source and to regulate electrical current and a resonance source circuit receiving current from the constant current source circuit. The resonance source circuit is constructed and arranged to be electrically connected with an electro-luminescent (EL) lamp so that the EL lamp receives alternating current. The constant current source circuit and the resonance source circuit are constructed and arranged such that when current flows from the constant current source circuit to the resonance source circuit and to the EL lamp, a maximum peak current received by a user contacting an output of the device or contacting the EL lamp is less than about 0.7 mA.
