Specific embodiment

It please refers to shown in Fig. 1, it to include micro- that show the particular circuit configurations of the preferred embodiment of the utility model Processor circuit 50, and be electrically connected with the microprocessor circuit 50 microwave detection circuit 10, light detection circuit 20, Power-switching circuit 30, LED drive circuit 40, the LED drive circuit 40 are connected with LED 41.The specific structure of each circuit and Function is as follows:

The microwave detection circuit 10: its induction part uses Microwave Detecting Technology, by the Doppler effect of microwave, It is exactly that detector persistently emits microwave, and receives the microwave signal being reflected back.It is primary to penetrate letter when the target in detecting area is mobile Number a frequency difference is had between the signal of reflection, then pass through microprocessor to determine whether there is detection to export, examined using microwave Survey principle realize be because microwave signal has certain penetration power, will not blocking and can not visit because of reading lamp lampshade It surveys.It cannot achieve if using traditional PIR detection technique, and the detection zone size of microwave is proper, if Using AIR detection technique, detection zone is too small, and induction is insensitive, can not meet the requirement of inductive effects.

The light detection circuit 20: the illuminance (brightness) of environment, the strong and weak letter of light are detected by light-sensitive element Number it is supplied to microprocessor circuit 50, microprocessor circuit 50 determines whether to light light bulb according to the signal of ambient brightness, real Existing induction on daytime not bright light, when evening dark, incude ability bright light.

The power-switching circuit 30: light bulb can be met in automobile battery voltage range (about 9 by power-switching circuit 30 ~16V) in can work, and the Working mould under reading lamp power switch different conditions is realized by the variation of detection power supply Formula:

A, power supply OFF: light bulb closed state, induction will not bright lights

B, power source ON: light bulb inductive mode incudes bright light, then incudes primary light-off

C, DOOR AUTO: the light on and off of light bulb is automatically controlled by car door, is not controlled by induction.

The LED drive circuit 40:LED driving circuit 40 is mainly the signal for receiving microprocessor circuit 50, to control LED's 41 lights and extinguishes, and guarantees that the brightness of the LED 41 in different electrical power voltage is all one by constant current drive mode Sample, while also preferably ensure that 41 service life of LED.

The microprocessor circuit 50: microprocessor circuit 50 is the core of entire light bulb.Mainly pass through processing microwave Signal, light detection signal and detection power state signal, accurately identify effectively in conjunction with the algorithm of decision logic and detection Induction movement, avoids the malfunction caused by other movements other than waving to incude.Signal is detected in conjunction with light to control LED 41 Lamp is lighted, while controlling the power supply and microwave analog signal of Microwave Detector, reduces the stand-by power consumption of product.
