Abstract
The utility model provides a novel solar energy timed light circuit with electric quantity control. The circuit is made into a CMOS integrated circuit, and connects with a few external devices to realize functions of solar light charging, light-induced control, discharge current control, timing control, etc. Based on a conventional solar light, an electric quantity control function is added in the circuit. When battery power of a product is low, the circuit reduces discharge current to achieve a purpose of ensuring a lighting time. The circuit is simple with few external devices, and the circuit is low in cost. The circuit can be heavily applied in various lighting products.
Description
Technical field
The utility model relates to the illuminating product of solar recharging.Like solar street light, solar energy garden lamp, solar lawn lamp etc.
Background technology
Not similar in the market, as to guarantee lighting hours solar energy illuminating product related circuit with the utility model.Solar energy illuminating product all is to charge the battery through solar panels daytime; Battery discharge illumination in evening; Unavoidably have the situation of weather conditions difference, cloudy day and sleety weather, the electric weight that daytime, the solar panels accumulators filled is seldom; If do not take appropriate measures, the time of illumination in the evening just falls short of.For outdoor lighting product functional, in most use occasions, would rather brightness low slightly, also must guarantee must bright lamp in certain period.So present solar energy illuminating product all has this respect defective.
Summary of the invention
In order to overcome above problem, the utility model provides a kind of circuit brand-new, can guarantee lighting time under suitable condition through the brightness that reduces lamp.
The utility model solves the scheme that its technical problem adopted: the utility model makes a CMOS integrated circuit, is used on the solar energy illuminating product.In the process of illuminating product work; When electric circuit inspection when the electric weight of battery has dropped to the magnitude of voltage of setting; Internal control through the utility model (detailed description see after face " embodiment "); Trigger internal circuit and reduce output current, thereby reach the purpose that guarantees lighting time, satisfies the basic function of use of product.The utility model has made the CMOS integrated circuit, and function all is to accomplish at IC interior, and control is accurate, and outward element is few, and is convenient for production, and consistency of product, stable very good.
The beneficial effect of the utility model is:
1, increased electric weight Detection & Controling function,, the lighting time of assurances needs, satisfied the basic function of use of product in the not enough situation decline low-light level of electric weight.
2, make the CMOS integrated circuit, control is accurate, and the simple outward element of circuit is few, and stability, the consistency of product are very good.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further
Accompanying drawing 1 is the inside frame principle figure of the utility model
Accompanying drawing 2 is utilization circuit diagrams of the utility model
Accompanying drawing 3 is outline drawings of the utility model encapsulating products with accompanying drawing 4
Embodiment
Accompanying drawing 1 is the inside frame principle figure of the utility model
Accompanying drawing 2 is utilization circuit diagrams of the utility model
In conjunction with accompanying drawing 1 and accompanying drawing 2, the practical implementation principle of the utility model is explained as follows:
In the accompanying drawing 2, B+ connects battery positive voltage, and S+ connects the solar panels positive pole; B-connects battery terminal negative, and S-connects the solar panels negative pole, and CDS is external photo resistance; R2 is external CDS divider resistance, and R is external constant-current discharge electric current adjustment resistance, and D1 is external load LED.
After inserting solar energy illuminating product; Daytime, solar panels S+ voltage exceeded cell voltage B+; The inner comparison circuit of the utility model triggers charging control circuit and opens, and solar panels charge a battery, when storage battery is full of the protection magnitude of voltage that reaches setting; Overcharge circuit and turn-off charging control circuit, reach the purpose that the protection storage battery is not overcharged damage.When solar panels S+ was not higher than storage battery B+, comparator can turn-off charging control circuit, avoided the storage battery reverse leakage.
Daytime, light was strong, and photo resistance CDS resistance is little, and the voltage of CDS and R2 dividing potential drop is high, and the photosensitive control circuit of the utility model triggers timing control circuit, and timing control circuit triggers control logic circuit, came the big efferent duct of breaking circuit, the load LED outage lamp that do not work; When dusk light deepening; It is big that photo resistance CDS resistance becomes, and the voltage step-down of CDS and R2 dividing potential drop is when partial pressure value is hanged down the set point that arrives the utility model; Photosensitive control circuit triggers timing control circuit; Timing control circuit triggers control logic circuit, the big efferent duct of open circuit, the discharging current that load LED sets according to the constant-current control circuit bright lamp of switching on;
The utility model is regulated the size of current of constant-current discharge through external R.
The MODE pin of the utility model is regularly the constant current mode control pin, and is unsettled respectively when the MODE pin, meet B+ and meet B-and connect method for three kinds, with three kinds of different timing constant current modes are provided.
Load LED switches in the process of bright lamp, and the electric weight of storage battery (being presented as the voltage of storage battery) slowly descends.If accumulator electric-quantity is sufficient, the utility model will be worked according to the timing constant current mode that the MODE pin is set, and turn off the light until regularly finishing LED; If accumulator electric-quantity is not enough; When battery tension drops to the magnitude of voltage of the utility model setting in the process of the bright lamp work of LED; Voltage detecting and control circuit will trigger the constant-current discharge circuit; Make the constant-current discharge circuit turn the discharge duty ratio down, be adjusted into the 1/3-1/6 of regular picture electric current to discharging current, little current discharge just is enough to guarantee that product accomplishes needed lighting hours. with the basic function of use (the situation downward modulation low-light level that electric weight is not enough guarantees the time) of reaching product.
Accompanying drawing 3 is outline drawings that the integrated circuit of the utility model is made SOP-8 or DIP-8 encapsulating products
Accompanying drawing 4 is outline drawings that the integrated circuit of the utility model is made the COB encapsulating products
The utility model is novel unique, and function is practical, and with low cost, market prospects are good, will be widely used in the various battery-driven illuminating products.
