Abstract

The invention discloses a single-lamp intelligent illumination circuit. The circuit is mainly formed by a sensor portion, a control circuit and an LED lamp bead array. The sensor portion comprises a human body infrared induction module and an environment brightness induction module and realizes intelligent induction to an environment. The control circuit portion comprises an LED driving circuit, an on-off control circuit and a light modulation control circuit and is used to realize on and off and brightness adjusting control of an LED lamp. The on-off control circuit achieves a main switch effect and can control lightening and quenching of the LED lamp bead array according to indoor light. The light modulation control circuit collects information transmitted by the human body infrared induction module and carries out linear dimming on the LED lamp so as to realize two state switching of LED lamp bead 100% brightness and LED lamp bead 15% brightness. The sensor portion is connected to the on-off control circuit and the light modulation control circuit and then controls on and off and brightness adjusting of the LED lamp bead array through the LED driving circuit. By using the circuit of the invention, single-lamp intelligent adjusting can be realized and operation cost is saved.

Description

technical field [0001] The invention relates to the lighting field, in particular to a single-lamp intelligent lighting circuit. Background technique [0002] Green light source LED is widely used in the fields of electronic display, indoor lighting and landscape lighting because of its advantages of high efficiency, energy saving, long life, environmental protection and pollution-free, small size, safety and reliability; the luminous efficiency of incandescent lamps and halogen tungsten lamps is only 15lm / W, fluorescent lamps are 70 lm / W, sodium lamps are 120 lm / W, and most of the remaining power consumption becomes heat consumption. LED has reached 150 lm / W, under the same lighting effect, [0003] The power consumption of LED is only about one-tenth of that of incandescent lamps and one-half of that of fluorescent lamps, but the price of LED lamps is relatively high. Only by adopting more energy-saving usage methods can the cost performance of LED lamps be improved. ...
