A set of perfect system of solar energy lawn lamp contains: light source, control device, battery, solar energy battery components and light body.
When on the day the sun in the solar cells, solar cells to turn light energy into electrical energy and through control circuit to electrical energy stored in the battery.
After dawn, and power in a battery by control circuit for lawn lamp LED light source power supply.
The next morning at daybreak, battery to suspend the lighting power supply, lawn lamp, solar battery for battery charging, cycle, cycle operation.
Solar energy lawn lamp parts control device is composed of MCU, sensors, through optical signal collection and discriminant part of manipulation of light source on and off.
The lamp body first and the decoration of the effect of system protection, ensure the normal working of the system.
In the light source, control device, battery is the key of the resolution lawn lamp system function.
Solar cells that convert solar energy into electricity, is more useful have monocrystalline silicon, polycrystalline silicon and amorphous silicon solar cells.
Monocrystalline silicon solar cell function parameter is stable, more suitable for rainy day, the sun is not very enough south area utilization.
Polycrystalline silicon solar cell production process is relatively short, lower than single crystal silicon, suitable for eastern and western area in the sun, sunshine is good enough to use.
Amorphous silicon solar cells on the sun light conditions is lower, is suitable for the local use in the outdoor sunlight lack.
Solar cells work voltage of battery voltage of 1.
5 times, talents to ensure to normal battery charging.
Such as to 3.
6 v battery charging demand with 4.
0 ~ 5.
4 v solar cells;
To 6 v battery charging demand with 8 ~ 9 v solar cells;
For 12 v battery charging needs 15 ~ 18 v solar cells.
solar street lamp
waterproof function for charging and discharging controller to phenomenon to drench, be affected with damp be affected with damp, shorting circuit board burn out of control devices,
, serious corrosion cause circuit board is metamorphic, cannot repair again.
Water ways mainly have two aspects: one is from the top of the light pole reserved Kong Shun solar battery components and light lead into the lamp pole;
From the gaps in the doors of light pole;
Coupled with the warehouse temperature is higher, the humidity inside the warehouse, cause the damage of the controller.
Therefore, completes the rainproof, avoid the controller be affected with damp be affected with damp, damaged, also cannot be ignored.
If you are a led street light manufacturers fan, you definitely want to enjoy the best possible. The that you choose plays a major role with the kind of experience you have when using it.
With comprehensive knowledge on solar light,why not visit the highly recommended site SRS Solar Street Light
to get a full appreciation of the best ?
