Abstract
The invention provides a drive and control circuit for preventing high-voltage thunder strike damage to a light-emitting diode (LED) light source. The drive and control circuit for preventing high-voltage thunder strike damage to the LED light source comprises a power circuit and a load which are electrically connected. A power output end is electrically connected with non-polar capacitors which has a larger capacity than an LED particle distributed capacitor. By means of the drive and control circuit for preventing high-voltage thunder strike damage to the LED light source, high-voltage surge during thunder strike can be suppressed effectively, and the LED light source is protected from damage.
Description
Technical field
The present invention relates to electronic technology field, refer to especially a kind of Drive and Control Circuit that prevents LED light source high pressure broken by lightning.
Background technology
Up to the present, the outdoor LED lighting is under the thunder and lightning environment, and spoilage is very high, and it has seriously perplexed applying of LED illumination, has become the problem that needs solution too impatient to wait.
Summary of the invention
The present invention proposes a kind of Drive and Control Circuit that prevents LED light source high pressure broken by lightning, and it can effectively suppress the high voltage surge of thunderstorm hour, and the protection LED light source is not damaged.
Technical scheme of the present invention is achieved in that
A kind of Drive and Control Circuit that prevents LED light source high pressure broken by lightning comprises power circuit and the load of electric connection, is electrically connected with capacity greater than the polarity free capacitor of LED distribution of particles electric capacity at power output end.
Preferably, described polarity free capacitor is provided with two, is arranged at respectively power supply and exports two ends between earth terminal.
Preferably, described polarity free capacitor is provided with two, between two outputs that is located at power supply, between output and earth terminal that one is located at power supply.
The present invention is by being electrically connected capacity greater than the polarity free capacitor of LED distribution of particles electric capacity at output, therefore the distributed capacitance of LED particle is little with respect to the capacitance of the distribution polarity free capacitor that increases, internal resistance is large with respect to the polarity free capacitor that increases, make high pressure when thunderbolt surge current to be formed on main loop with the polarity free capacitor that increases, therefore directly utilize this polarity free capacitor bypass high pressure release earth terminal or output; The electric current that the surge current that makes high pressure be struck by lightning only has less LED light source to bear flows through, thereby has protected LED light source not to be subjected to the high pressure broken by lightning.
