Abstract
A solar energy automatic light modulation drive circuit mainly comprises a rectifier filter circuit, a drive circuit and an output circuit; the rectifier filter circuit is connected with the drive circuit and simultaneously connected with a timing IC power supply circuit; the timing IC power supply circuit is respectively connected with the drive circuit and a current detection circuit through an automatic conversion power circuit; the output circuit is connected with the current detection circuit; the solar energy automatic light modulation drive circuit can be widely applied in corridor lamp usage and office night lighting usage; when night comes and people start to be active, the lamps are bright enough to satisfy daily activity requirement of people without affecting illumination; when night is out after four hours, people start to rest, brightness can be lowered, and illumination condition can be only satisfied.
Description
Technical field
The utility model relates to lighting electronic application circuit field, is specifically related to a kind of solar energy drive circuit with an automatic light meter.
Background technology
Solar energy illuminating light source, has the remarkable advantages such as energy-saving and environmental protection and life-span length.Along with global awareness of saving energy is day by day rooted in the hearts of the people, under the overall situation of global energy high flow rate, people the focus of paying close attention to focus on solar energy this " illuminate following technology " and the lighting field revolution for the third time that brings thus on.According to statistics, with solar lighting, replace whole incandescent lamps or part fluorescent lamp, China just can save 1/3 electric consumption on lighting amount every year, this is equivalent to save the annual energy output of Three Gorges Projects, not only can alleviate the nervous situation of China's power requirement, can also reduce Coal-fired capacity (more than 70% energy output of China is to rely on coal-fired acquisition at present), reduce the pollution to environment.Existing solar energy illuminating light source can not be realized according to mankind's activity rule brightness is regulated, especially work as the dead of night, people do not need so large brightness in rest, as long as it is just passable to meet lighting condition, but this function can not be realized in current solar energy illuminating light source.
Utility model content
The utility model provides a kind of solar energy drive circuit with an automatic light meter, the problem that can not regulate to solve brightness that prior art exists.
The utility model is mainly comprised of current rectifying and wave filtering circuit, drive circuit and output circuit, when solving technical scheme that its technical problem adopts and be current rectifying and wave filtering circuit and be connected with drive circuit, be connected with timing IC power supply circuits, regularly IC power supply circuits are connected with current detection circuit with drive circuit respectively through automatic transfer power circuit, and output circuit is connected with current detection circuit.
Above-mentioned current detection circuit comprises total power current detection circuit and half-power current detection circuit.
The operation principle of the utility model device is direct current 12V provides operating voltage through current rectifying and wave filtering circuit for drive circuit, through the three-terminal voltage-stabilizing circuit in IC power supply circuits regularly, provide operating voltage for the drive IC in timing IC power supply circuits simultaneously, automatically transfer power circuit conversion IC work, output output high level drives triode, relay obtains electric, the normal closure of making war, normally closed point disconnects, the normal closed total power testing circuit that connects of making war, power work is in full power state work, after setting-up time, conversion IC output, output low level, triode is closed, relay power-off, normal battle disconnects, normally closed closed, the normally closed closed half-power testing circuit that connects, power supply is converted to the work of half-power state.
Compared with prior art; the utility model is widely used in corridor lamp use and cubicle night lighting is used; when the evening draws on; people are in active stage; the brightness enough bright people's of meeting daily routines does not affect illumination; after after four hours, in the dead of night, people do not need so large brightness in rest, as long as it is just passable to meet lighting condition.
