The utility model is for the occasion that does not need the long-time continuous highlight illumination on the present market for underground garage etc., realized a kind of infrared-sensing type LED sectional dimming power supply, the luminous efficiency of LED own is just high a lot of than common fluorescent lamp, the utility model adopts the infrared induction sectional dimming simultaneously, when the personnel of having sensed or vehicle enter, the LED fluorescent lamp is transferred to high-high brightness, when nobody, automatically lower brightness is transferred in the brightness of LED fluorescent lamp, thereby is realized energy-conservation effect.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Embodiment
A kind of infrared-sensing type LED dimming power source mainly comprises: Infrared Detectors 102, infrared signal Check processing and delay control circuit 103, LED power supply dimming controlling module 104, LED electric power driving module 105, power supply processing module 106 as shown in Figure 1.
Among Fig. 1 101 is expression infrared heat sources, the temperature of human body or the vehicle itself that travels all temperature than surrounding environment is high, thereby will send the infrared ray that stronger human eye cannot be seen, in close LED lamp certain limit of the present utility model, the infrared ray that personnel or the vehicle that travels send will be detected by Infrared Detectors 102, and Infrared Detectors 102 is converted to voltage signal with the infrared signal that detects and sends infrared signal Check processing and delay control circuit 103 to.
Infrared signal Check processing and delay control circuit 103 adopt general BISS0001 control chip, the input of BISS0001 chip has the window selection device, mainly process for the voltage signal that changes, when the signal of sending here when Infrared Detectors 102 does not have to change (such as being parked in for a long time car motionless in the garage) or changes very little (such as toy etc.), the BISS0001 chip is output not, when only having the signal intensity of sending here when Infrared Detectors 102 to acquire a certain degree Δ V, one section control signal of BISS0001 chip output, control LED power supply dimming controlling module 104.When continuous variable signal during greater than voltage Δ V, the BISS0001 chip signal output exists always, and after variable signal finished, output signal continued time-delay Δ T and finishes after the time.The time Δ T of the voltage Δ V of BISS0001 chip input window and the time-delay of output control signal determines by BISS0001 chip and peripheral capacitance-resistance thereof.
LED power supply dimming controlling module 104 mainly contains resistance and metal-oxide-semiconductor forms, and is used for controlling LED electric power driving module 105 and carries out light modulation.Because LED does not need stepless dimming in the application scenario of the present utility model, therefore do not need complicated PWM dimming mode, but by controlling the turn-on and turn-off of metal-oxide-semiconductor, the feedback resistance that changes 105 li of LED electric power driving modules comes the regulation output electric current to carry out light modulation.
LED electric power driving module 105 is used for output LED supply current, and it receives the output signal of LED power supply dimming controlling module (104), according to the turn-on and turn-off of metal-oxide-semiconductor, changes feedback resistance, thereby the regulation output electric current reaches the purpose of light modulation.
Power supply processing module 106 mainly obtains the 5V DC power supply from the alternating current 220V power supply by measures such as step-down rectifiers, can work to guarantee Infrared Detectors 102, infrared signal Check processing and delay control circuit 103, LED power supply dimming controlling module 104.
In sum, the course of work of the present utility model is: when having personnel or vehicle to enter, Infrared Detectors 102 detects infrared signal, control LED power supply dimming controlling module 104 after infrared signal Check processing and delay control circuit 103 processing, thereby control LED electric power driving module 105, the brightest state (i.e. 100% electric current output) is transferred in LED output, when personnel leave or vehicle motionless after, the variable signal of Infrared Detectors 102 disappears, infrared signal Check processing and delay control circuit 103 stop output at continuation output Δ T after the time, thereby control LED electric power driving module 105 is transferred to LED output glimmer state (namely 20% electric current is exported) after the Δ T time, thereby reaches both emergency lightings by energy-conservation effect.
