120 w solar street light prices1

Solar garden light LED lighting system, in addition to saving energy and reducing consumption, also has a maintenance-free features, its working principle is simple, using the light born v effect principle made of solar cells, solar panels during the day to receive solar radiation and translated into electricity output,

LED lighting system of solar garden light in addition to saving energy and reducing consumption, also has the characteristics of free maintenance, and its working principle is simple. Using the photovoltaic effect principle of solar cells in the day to receive solar radiation energy, and convert it into electricity and stored in the storage battery by the controller. In the evening, when the intensity of illumination gradually reduced to about 10 lux and solar panels of the open circuit voltage is 4. When the voltage is about 5 v, controller detects the voltage value, after the battery to discharge lamp holder. Battery discharge after 10 hours, controller, battery discharge, street lighting. Solar battery charging and discharging controller automatic control, lighting control, manual control and time control to open the lamp, and through the time close the lamp. For battery charging and for electrical power supply control device has a battery charging and discharging protection and electrical time control function. When battery voltage up to 14, the solar cell by controller for battery charging. In 5 v, the controller output pulse; Medium voltage charging, when the battery voltage to 15. In 3 v, controller stop to recharge the battery. The controller can prevent overcharge. When the battery voltage drop to 13 v, restore charge controller. In the evening, solar battery voltage is lower than 4. When the voltage is 7 v, the controller open, automatic timing controller. According to the position of switch controller, determine the closing time of street lamp, can be in 3 - open time Adjustment between 3 ~ 10 hours. When the battery voltage up to 10. When the voltage is 5 v, the controller will shut off the power and close the electrical appliances. When voltage protection is insufficient, indicator light will be green, indicator light will protect the battery in an hour. Solar garden light, jschindo。 com) Should reasonable use light energy to prevent glare. Its light irradiation should follow the required point of view, and fell on the road in a particular mode. Uniform light distribution, road surface bright, glare. In order to reduce the glare, light can be distributed control over the maximum intensity.
