Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 1, accompanying drawing 3 ~ 5, a kind of intelligent Fog-proof light, this Fog-proof light 1 is mounted on street lamp bracket, it comprises radiating subassembly 14, the LED group 12 be arranged on radiating subassembly 14, the reflection shield 13 covered in LED group 12, the convex lens 11 that are connected with the uncovered portion of reflection shield 13, the face that described convex lens 11 contact with extraneous air is plane, its reverse side is convex surface, is coated with one deck film plating layer 111 on the surface of this convex surface; Described Fog-proof light 1 also connects an intelligent drive circuit 4; Described intelligent drive circuit 4 main circuit is made up of inductance coil L1, electric capacity C1, diode D1, diode D5 and switching tube Q1, described electric capacity C1, diode D5 connect, described inductance coil L1, diode D1 connect, in parallel after two circuit connected in series, connecting valve pipe Q1 after in parallel; The circuit of electric capacity C1, switch Q1, diode D2, diode D4 and inductance coil L2 composition is output stage, and described electric capacity C1, diode D2 connect, in parallel with diode D4 after series connection, and the two ends after parallel connection are connecting valve pipe Q1, inductance coil L2 respectively.
Please refer to accompanying drawing 1, described Fog-proof light 1 is electrically connected control box drive unit 3, and this control box drive unit 3 is electrically connected a solar cell photovoltaic plate 2, is provided with lithium battery in described control box drive unit 3, solar cell photovoltaic plate 2 pairs of lithium cell chargings.
Please refer to accompanying drawing 5, described film plating layer 111 is translucent yellow film plating layer 111, Intelligent dimming circuit adopts PWM dimming mode, and LED sends strong white light, does not produce colour cast, Intelligent dimming circuit energy-saving effect comparatively shows, gold-tinted is utilized easily to penetrate principle, the strong white light that LED sends, after plating yellow rete, penetration power is strengthened, and can see road surface clearly very clearly.Can remove inert gas injecting in Fog-proof light 1 from, decrease this technique, the cost of inert gas is higher than coating process, therefore, adopts plated film that cost can be made to reduce.Also be connected with PWM integrated manipulator in the circuit of described intelligent drive circuit 4, its model is HV931.Be connected with commutating voltage circuit in the circuit of described intelligent drive circuit 4, be composed in series by diode D1, inductance coil L1, switching tube Q1, resistance Rs1.
Please refer to accompanying drawing 2, be the utility model Fog-proof light intelligent drive circuit figure, main circuit is the non-isolated constant current output circuit of a single-stage single-switch.The circuit be made up of L1, C1, D1, D5 and Q1 is input stage, works in discontinuous conduction mode, and the circuit be made up of C1, Q1, D2, D4 and L2 is output stage, under being operated in continuous conduction mode.Two-stage shares a power switch pipe Q1, and electric capacity C1 is equivalent to load to input stage, is equivalent to dc source to output stage.System step-down ratio is the product of two-stage step-down ratio, does not need transformer just can realize lower voltage like this export by mains-supplied.During switch Q1 conducting, input stage current path: in commutating voltage → D1 → L1 → Q1 → Rs1, L1, electric current linearly increases, output stage Buck circuital current path is: C1 → Q1 → Rs2 → LED → L2, C1 provides energy; When Q1 turns off, the energy in input stage current path: L1 → C1 → D5 → D1, L1 forwards in C1, and because D1 exists, L1 electric current can not be reverse, and it is interrupted that L1 electric current reduces to 0 after-current; Output stage current path: L2 → D4 → LED, because optimum configurations is different, in L2, electric current not only can not become 0, and fluctuation is relatively little.
Circuit working is under peak-current mode, and oscillator makes GATE export high level, and Q1 admittance is led to; CS1 and CS2 terminal is the reverse input end of two voltage comparators of HV9931 inside respectively, the input in the same way of two comparators is chip internal ground connection, circuit detects input current and output current by CS1 and CS2 terminal simultaneously, CS1 is input current signal detection terminal, CS2 output current signal detection terminal, as long as these two terminals are with having the voltage ratio on a terminal low, GATE terminal is with regard to output low level, and Q1 just turns off.VDD is the reference voltage output pin of chip, the peak inrush current in Rs1, Rcs1 and Rref1 programmable L1, Rs2, Rcs2 and Rref2 programmable output current.Can think within the cycle of alternating current dutycycle and switch lock constant, therefore input current peak envelope line is sinusoidal wave, and average current be sine wave, can real auspicious PFC.
C2 is input capacitance, and as high frequency bypass, if with bulky capacitor, circuit loses power factor emendation function.RT correspond to internal oscillator, has two kinds of connections, sets constant operation respectively frequently and the constant turn-off time, and what adopt in figure is the connection of constant turn-off time.PWMD pin is digital dimming signal input pin, and when this pin is high level, circuit normally works, GATE pin output low level all the time when this pin is low level, and switching tube Q1 breaks, and drive circuit does not work.
When ambient light is the poorest, the PWM dutycycle of the utility model light modulation letter close to 100% time make that LED is the brightest meets illumination requirement; Automatically can change the dutycycle of the PWM of dim signal when ambient lighting changes according to the power of exterior light photograph, make LED corresponding dark, but illumination meet the demands; In addition, suitably brightness can be reduced when people is fewer at dead of night.
Realize this requirement and will have a good light intensity sensor.Photo resistance poor linearity, frequency response is low, and phototriode is highly sensitive, but temperature characterisitic and poor linearity system select TLS2561 as photoelectricity intensity sensor.Light intensity signal, close to the reaction of human eye to brightness, directly can be changed into data signal and export, have the I2C interface of programmable Interrupt function and standard, can be connected with single-chip microcomputer easily by TLS2561.PIC16C62 single-chip microcomputer selected by single-chip microcomputer, this single-chip microcomputer stable performance, exports, can realize I2C bus communication easily with PWM.Light intensity sensor TLS2561 converts optical signal to data signal and is sent to single-chip microcomputer, produces the pwm signal of light modulation through single-chip microcomputer process, and light modulation PWM signal delivers to the PWMD end of HV9931, to realize PWM intelligent dimming.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
