Abstract: A timer may include a power plug, an AC/DC transforming circuit, a relay circuit, a recharging circuit, and a control circuit that includes a relay output, a key input, and an LCD output. The timer may further include a 2.4V battery and a main body. In one embodiment, the key input includes a plurality of buttons. By pressing one or more of these buttons, signals can be transmitted into the key input of the control circuit. The timer may further include an LCD display and the information displayed thereon is transmitted from the LCD output of the control circuit. The power plug can be connected to an AC power source to bring in the power to the AC/DC transforming circuit to generate a 12V DC current that can be transmitted to the recharging circuit to charge the 2.4V battery, as well as providing power to the relay circuit.

Abstract: An intelligent lighting apparatus may have a rechargeable battery, a power processing unit, a power managing unit, a detecting module, and a light source. In one embodiment, the power managing unit is configured to detect a power outage, and when the power outage occurs, the power managing unit can switch the power source to rechargeable battery to continue providing electrical power to the light source. The endurance depends on the capacity of the battery and the power consumption of the light source. In another embodiment, the light source is a regular light bulb. In a further embodiment, the light source is an LED light bulb. In still a further embodiment, the rechargeable battery is a lithium battery. In an exemplary embodiment, the power managing unit in the present invention is configured to enable the light source to be controlled by wall switches even during the power outage.
