Chongqing solar street lamps factory

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 light born v effect principle of solar cells, solar panels during the day to receive solar radiation and translated into electricity output,

solar garden light LED lighting system has the characteristics of saving energy and reducing consumption, and free maintenance. 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 output. Solar panels are stored in the storage battery by the controller. In the evening, when the illumination was gradually reduced to about 10 lux, solar panels open circuit voltage is 4. When the voltage is about 5 v, controller detects the voltage value, the battery to discharge lamp cap. 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 give a battery of electric power supply control device has the function of the charge and discharge and control electric time. When the battery voltage to 14, solar battery through the controller to recharge the battery. 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. Control can prevent overcharge. When the battery voltage drop to 13 v, restore charge controller. In the evening, solar battery voltage is lower than 4. In 7 v, when the controller opens, the controller will automatically give light timing. According to the position of controller toggle switch, the lights determine the closing time. Boot time can be adjusted between 3 to 3 ~ 10 hours. When the battery voltage up to 10. When the 5 v, the controller will shut off the power and close the electrical appliances. Under-voltage protection, indicator light will be green, 1 hour after the indicator light will protect the battery. Solar garden light, jschindo。 com) Should reasonable use of light energy to prevent glare. It should light irradiation in the desired Angle, and landed on the road in a particular pattern. Uniform light distribution, road surface bright, glare. In order to reduce the glare, can be in more than the maximum intensity of light distribution control.
