Abstract
The invention provides a solar night timing lamp circuit. The circuit mainly comprises a charging circuit (6), a switch control circuit (8), a time control circuit (7), a boost control circuit (9), a solar cell (10), an external resistor (11), an external inductor (12), an external capacitor (13), a light-emitting diode (14) and a rechargeable battery (15), wherein when a product is started to illuminate, the time control circuit (7) starts timing after obtaining a trigger signal and output a signal after a predetermined period of time, so the overall night lamp circuit stops illuminating. An overall integrated circuit adopts a CMOS process and has less peripheral elements and very little power consumption, so the efficiency of the integrated circuit is effectively improved.
Description
Technical field
The present invention relates to various use solar panels charges to rechargeable battery and realizes the automatic product of illumination at night.As solar lawn lamp, Christmas lamp, garden lamp, doorplate lamp, traffic lights, outdoor LED lamp string etc.
Background technology
There is not solar product in the market with the similar timing working of the present invention.Solar product impinges upon solar panel charging by available light energy is provided, and it is more to charge when fine light is strong, and overcast and rainy light secretly then charges seldom.The automatic illuminating product of solar energy in the market, automatically light when darkness light is very dark, at day extinguished automatically by second day, as the electricity that fills is not enough, can not continue to work until daybreak in second day, and the discharge limit of the rechargeable battery of then working is (as solar lawn lamp, rechargeable battery discharges into 0.8--1.0V) just can turn-off, and in fact, the automatic illuminating product of this class solar energy every night only need be from darkness, and the functional requirement of product was just satisfied in continuous operation in 6 hours.This series products in the market because be not to get on to control lighting the time of lamp from the time, but by charging how much decide lighting the time of lamp, just caused the charging bright lamp that still discharges after midnight for a long time, the waste electric energy; Charging is few because of proxima luce (prox. luc) electric weight savings in the battery after a little while, and can not satisfy the most basic time requirement of the bright lamp work of circuit.In order to solve the problem of this respect, like product in the market all is by strengthening solar panels (cost rising), increase charge power and guarantee the product groundwork every day time with reduction discharge power (promptly reduce the brightness of lamp, the performance of product descends).
Summary of the invention
In order to overcome above problem, the invention provides a kind of solar energy night lamp circuit of brand-new band time control, new circuit has solved the problem of solar energy lamp at night discharge time uncontrollable (fill more and put more, fill less less and put).
The present invention solves the scheme that its technical problem adopts: on original solar energy night lamp circuit basis, add RC duration of oscillation control circuit.When the same day, the black light line was dark, product starts and begins illumination, time control circuit obtains picking up counting after the triggering signal, during to the time span set, the time control circuit output signal makes whole night lamp circuit lighting-off luminous, comes this off state of holding circuit and only keep minimum discharge, to daybreak next day, product enters charged state.Because lighting hours is controlled, can strengthen the discharge power of entire product, increased the brightness of lamp.The present invention is integrated together the charging circuit of entire product, start-up control circuit, booster driving circuit and time control circuit, make the CMOS integrated circuit, can effectively reduce product cost, electric energy is utilized effectively, and consistency of product, stability get a promotion.
The invention has the beneficial effects as follows:
1, effectively utilized the rechargeable energy of solar panels.
2, product need not strengthen solar panel in order to guard against undercharge not enough problem of lighting time, effectively reduces product cost.
3, the brightness of illumination of product improves, and has promoted the performance of product.
4, make the CMOS integrated circuit, stability, the uniformity of product are improved.
