Abstract
A micro-power-consumption light-controlled LED (light emitting diode) infrared lamp is a practical device which is integrated by a constant-current capacitor element, infrared LEDs, a light dependent resistor and a silicon-controlled rectifier resistor-capacitor element. An anode of a bridge rectifier is connected with a silicon-controlled rectifier, a cathode of the silicon-controlled rectifier is connected with a cathode of the bridge rectifier by a plurality of infrared LEDs connected in series, a control electrode of the silicon-controlled rectifier is connected with a pull-up resistor R2 and a pull-down light dependent resistor Rz through a resistor of hundred kilo-ohms. The silicon-controlled rectifier is turned on when the resistors are in the light, power-consumption current is about thirty microamperes the silicon-controlled rectifier is turned off when the resistors are in the dark, the LEDs are lighted, and the power-consumption current is about twenty milliampheres. The micro-power-consumption light-controlled LED infrared lamp is compact in structure, safe and stable, efficient and energy-saving.
Description
Technical field
The utility model relates to a kind of infrared illuminator, little power consumption light-operated LED infrared lamp that especially suitable watch-dog uses.
Background technology
At present, be used for that infrared illuminator that watch-dog uses is most to adopt manually control,, adopt himself power consumption of light-operated infrared illuminator product also bigger than normal though have in case forget and close then become altar lamp.The current energy-saving low-carbon of advocating, requirement provides a kind of product of little power consumption.
Summary of the invention
In order to overcome the deficiency of existing product, the utility model provides a kind of little power consumption light-operated LED infrared lamp.
The utility model solves the technical scheme that its technical problem adopted: adopt the electric capacity constant flow element, the utility unit that infrared LED luminous tube, photo resistance, controllable silicon Resistor-Capacitor Unit integrate, the anodal controllable silicon that connects of bridge rectification; The controllable silicon negative pole connects bridge rectification negative pole through some series connection infrared LEDs, and the SCR control utmost point connects pull-up resistor R2 and drop-down photo resistance Rz through 100k Ω resistance, and controllable silicon ends during bright resistance; The about 30uA of static current of lcd; Controllable silicon conducting during resistance in the dark, LED lights, and structure is simple and direct; Safety and stability, energy-efficient.
The beneficial effect of the utility model: light source and control circuit are one, and be simple in structure, and the monitoring power consumption is 30 microamperes, and power savings is obvious.
