Below the content of each width of cloth accompanying drawing expression of the utility model specification and the mark among the figure are made brief description:
Fig. 1 connects block diagram for the utility model module;
Fig. 2 is the utility model circuit theory diagrams;
Embodiment
Referring to Fig. 1 as can be known, the utility model is a kind of power control system of controlling led array and/or mains lighting supply, and it mainly is made up of first detecting module 10, second detecting module 20 and control module 30.
First detecting module 10 has the infrared acquisition function, form by infrared acquisition Fresnel Lenses, sensing element and signal processing circuit, the Infrared wavelength that the infrared acquisition Fresnel Lenses is surveyed is 9.64-9.67 μ m, sensing element is pyroelectricity unit D1 spare or light-sensitive element, and signal processing circuit is made up of signal first order amplifying circuit A1 and bandpass filtering and second level amplifying circuit and is constituted.
Second detecting module 20 has the ultraviolet detection function, form by ultraviolet detection Fresnel Lenses, sensing element and signal processing circuit, sensing element is pyroelectricity unit D2 spare or light-sensitive element, and signal processing circuit is made up of signal first order amplifying circuit A2 and bandpass filtering and second level amplifying circuit and is constituted.
The power control system operation principle:
One, when power supply place opening, the control system operation principle
When no human body moved, infrared Fresnel Lenses can't obtain the infrared light of specified wavelength, and pyroelectricity element D1 is in resting state, and power contact T often opens, and promptly under the situation that does not have human body to move, power supply does not provide illumination.
When human body moves, the infrared acquisition Fresnel Lenses obtains the human body infrared light and is gathering after the enhancing on the pyroelectricity element D1, pyroelectricity element D1 receives the human body infrared radiation, and the temperature of pyroelectricity element D1 changes, and loses charge balance and outwards emits electric charge; Through amplifying circuit A1 first order processing and amplifying, and after bandpass filtering and the amplifying circuit second level processing and amplifying, B sends high level signal to triple gate, the state of control power contact T.
Two kinds of possibility situations are arranged this moment:
1, when if the ultraviolet detection Fresnel Lenses detects ultraviolet light, external environment is in the state in daytime, the ultraviolet detection Fresnel Lenses gathers on the pyroelectricity element D2 after the ultraviolet light that obtains is strengthened, pyroelectricity element D2 closes under the irradiation in ultraviolet and discharges electric charge, sends high level signal to triple gate B after subsequent conditioning circuit is handled.At this moment, triple gate B does not produce control signal when receiving the high level signal that the high level signal that first detecting module 10 sends and second detecting module 20 send, and power contact T often opens.
2, when not detecting ultraviolet light as if the ultraviolet detection Fresnel Lenses, external environment is in the state at night, second detecting module 20 does not send high level signal, at this moment, the high level signal control power contact T closure that the triple gate signal sends according to first detecting module 10, led array gets.
Two, when power supply place closed condition, the control system operation principle
Be under the closure state at power contact T, if human body leaves the investigative range of first detecting module 10, the infrared acquisition Fresnel Lenses can't obtain the human body infrared light, and first detecting module 10 does not produce high level signal, triple gate B control power contact T often opens, and led array must not.
Be under the closure state at power contact T, if when the ultraviolet detection Fresnel Lenses detected ultraviolet light, second detecting module 20 sent high level signal, this moment, no matter whether second detecting module 20 sent high level signal, triple gate B control power contact T often opens, and led array must not.
