Description
Technical field:
This utility model relates to solar lighting technical field, is the relative all-weather solar controller for road lamp of a kind of practicality.
Background technology:
Existing solar street lamp controller, the commonly used charging modes such as PWM pulsewidth modulation, MPPT MPPT maximum power point tracking, electrode automatic identification technology, anti-overcharge, overdischarge road design, constant current, constant voltage circuit, and the man machine interface etc. of every regulation, increase control power consumption, fault rate and cost of investment the most on the contrary.And relative round-the-clock illuminating effect cannot be realized.
Summary of the invention:
The technical solution of the utility model: according to the VF value of LED chip, is magnitude of voltage during its luminous quantity maximum；And light efficiency the highest be under a voltage section.
It is first depending on the unlatching voltage drop value that time at dusk, photovoltaic battery panel provides, makes field effect transistor after of short duration time delay, open LED light source.
LED light source has been designed with the technical scheme of natural regulation and control: both according to the VF value of the series connection progression≤LED chip of the charging upper limit voltage/LED light source of accumulator, thus having ensured that continuous sunny sky upper limit running voltage will not surpass, LED chip is operated in the voltage section that light efficiency is the highest.Progression in parallel≤LED chip the power of the series connection progression/LED light source of the Upper Bound Power/LED light source according to LED light source design, thus ensured that continuous sunny sky Upper Bound Power will not surpass.
Utilize the slope of LED chip VA characteristic curve, steadily reduce luminous flux.Initial voltage is the highest, and electric current is the biggest, and pressure drop is the fastest, and progressively reaches unanimity with initial voltage situation time low, it is achieved the pressure drop process of regulation and control naturally.Fall power illumination also complies with human-based management requirement the most after midnight, and has ensured that continuous 30 overcast and rainy batteries are only put, it is achieved thereby that the effect of the most round-the-clock illumination of solar street light.
At dawn, according to the boost value that early morning, photovoltaic battery panel provided, field effect transistor is made to close LED light source after of short duration time delay.
Implementation:
According to electrical schematic diagram designing printed circuit board, part lived by dotted line frame, respectively photovoltaic battery panel, LED light source and accumulator and pad thereof.Use Zener diode in parallel with the pad of photovoltaic battery panel, limit charging superpressure.Schottky diode is used to seal in charge circuit, it is to avoid accumulator recoils.Use capacitor delay circuit to trigger small-power field effect transistor, prevent switching process from flashing.Use, adjust biasing resistor driving high-power FET entrance degree of depth saturation region, it is achieved high effect is run.
This utility model is the relative all-weather solar controller for road lamp of a kind of practicality, it is to be made up of Zener diode, Schottky diode, resistance, capacitor, field effect transistor, it is characterized in that: after it uses photo field effect pipe to open LED light source, continue with the pressure drop of accumulator, naturally the lighting process of this street lamp is regulated and controled, to light-operated shutoff.
Accompanying drawing illustrates:
Accompanying drawing 1 is the circuit diagram of the relative all-weather solar controller for road lamp of a kind of practicality of this utility model.
Wherein 1, Schottky diode, 2, resistance R1,3, resistance R2,4, LED light source, 5, accumulator, 6, photovoltaic battery panel, 7, Zener diode, 8, resistance R2,9, capacitor, 10, field effect transistor G1,11, resistance R4,12, field effect transistor G2.
Detailed description of the invention:
This is the embodiment of relative all-weather solar controller for road lamp practical for a 50W.
Accompanying drawing 1 is circuit diagram, first by the photovoltaic battery panel (6) of rated voltage 18V rated power 60W, in parallel with the Zener diode of 14V/10W (7), then by the Schottky diode (1) of 20V/5A, the accumulator (5) of 12V/45AH is charged.The control signal that photovoltaic battery panel provides is by biasing resistor R1 (2), resistance R3 (8) and the adjustment of delay capacitor (9), by 20V/1W field effect transistor G1 (10), adjustment through biasing resistor R2 (3), R4 (11) drives high-power FET (12) to enter degree of depth saturation region, it is achieved high effect is run.Make LED light source (4) both end voltage be about 13V, use 5730/0.5W chip 100,25 and 4 strings to constitute 50WLED light source.Constitute the relative all-weather solar street lamp of practicality, suitable vast city, township road road solar street light universal.
